QT dispersion in patients with arrhythmogenic right ventricular dysplasia. (1/272)

AIMS: Arrhythmogenic right ventricular dysplasia is a rarely diagnosed cardiomyopathy, but a frequent cause of ventricular arrhythmia and sudden cardiac death. QT interval dispersion, measured as an interlead variability of QT, is a marker of dispersion of ventricular repolarization and, hence, of electrical instability. The present study was conducted to assess the occurrence of QT dispersion and its modulation during treatment with sotalol. Methods Twenty-five patients with the diagnosis of arrhythmogenic right ventricular dysplasia were studied retrospectively. Fourteen patients were considered low risk for malignant ventricular arrhythmia and sudden cardiac death, and 11 high risk due to documented sustained ventricular arrhythmia, cardiac arrest, or sudden cardiac death. Twenty five healthy volunteers served as control subjects. RESULTS: Dispersion of repolarization was significantly higher in patients than in control subjects (QTd and JTd: P<0.05). Dispersion of repolarization was equal in patients both with and without malignant arrhythmias. There was no significant change in dispersion after treatment with sotalol. Adjacent QT dispersion between leads V3-V4, V4-V5 and V5-V6, respectively, was higher in patients than in control subjects (P<0. 05), while no differences were seen in leads V1-V2 and V2-V3. CONCLUSION: QT interval dispersion is increased in patients with arrhythmogenic right ventricular dysplasia. However, the degree of dispersion is not related to the severity of symptoms, nor is it influenced by treatment with sotalol.  (+info)

Signal-averaged electrocardiogram in patients with arrhythmogenic right ventricular cardiomyopathy and ventricular arrhythmias. (2/272)

OBJECTIVE: The aim of the study was to assess the prevalence, sensitivity, specificity and predictive value of the signal-averaged ECG in patients with arrhythmogenic right ventricular cardiomyopathy and different forms of ventricular arrhythmias. METHODS: The signal averaged ECG in 138 patients and 146 healthy subjects (control group), using a three bandpass filter system (25-250, 40-250, 80-250 Hz), was considered abnormal when at least two parameters were abnormal at each filter setting. Patients were divided into three groups according to the extent of the right ventricular enlargement (mild, moderate, extensive), and into five groups according to the type of ventricular arrhythmia. RESULTS: The signal averaged ECG was abnormal in 57% of the patients and in 4% of the healthy subjects. The sensitivity was 57%, specificity 95% and positive predictive value 92%. The signal averaged ECG was abnormal in 94.4% of patients with the extensive form of the disease, in 77.7% of patients with the moderate form and in 31.8% of patients with the minor form, demonstrating good correlation with the extent of the disease. According to the type of ventricular arrhythmia, a higher correlation was found between signal averaged ECG abnormality and sustained ventricular tachycardia with superior axis (94.4%, P<0. 02); the correlation for the other arrhythmias varied from 16.6% to 55.8%. CONCLUSION: There is a closer correlation between the signal averaged ECG and extent of disease than with the presence of ventricular arrhythmias. The signal averaged ECG is not helpful in diagnosing minor forms of the disease, but since it is a non-invasive method, it may be useful in evaluating progression of the disease.  (+info)

The locus of a novel gene responsible for arrhythmogenic right-ventricular dysplasia characterized by early onset and high penetrance maps to chromosome 10p12-p14. (3/272)

Arrhythmogenic right-ventricular dysplasia (ARVD), a cardiomyopathy inherited as an autosomal-dominant disease, is characterized by fibro-fatty infiltration of the right-ventricular myocardium. Four loci for ARVD have been mapped in the Italian population, and recently the first locus was mapped in inhabitants of North America. None of the genes have been identified. We have now identified another North American family with early onset of ARVD and high penetrance. All of the children with the disease haplotype had pathological or clinical evidence of the disease at age <10 years. The family spans five generations, having 10 living and 2 dead affected individuals, with ARVD segregating as an autosomal-dominant disorder. Genetic linkage analysis excluded known loci, and a novel locus was identified on chromosome 10p12-p14. A peak two-point LOD score of 3.92 was obtained with marker D10S1664, at a recombination fraction of 0. Additional genotyping and haplotype analysis identified a shared region of 10.6 cM between marker D10S547 and D10S1653. Thus, a novel gene responsible for ARVD resides on the short arm of chromosome 10. This disease is intriguing, since it initiates exclusively in the right ventricle and exhibits pathological features of apoptosis. Chromosomal localization of the ARVD gene is the first step in identification of the genetic defect and the unraveling of the molecular basis responsible for the pathogenesis of the disease.  (+info)

Arrhythmogenic right ventricular dysplasia/cardiomyopathy: need for an international registry. Study Group on Arrhythmogenic Right Ventricular Dysplasia/Cardiomyopathy of the Working Groups on Myocardial and Pericardial Disease and Arrhythmias of the European Society of Cardiology and of the Scientific Council on Cardiomyopathies of the World Heart Federation. (4/272)

Arrhythmogenic right ventricular (RV) dysplasia/cardiomyopathy (ARVD/C) is a heart muscle disease characterized by peculiar RV involvement and electrical instability that precipitates ventricular arrhythmias and sudden death. The purpose of the present consensus report of the Study Group on ARVD/C of the Working Groups on Myocardial and Pericardial Disease and Arrhythmias of the European Society of Cardiology and of the Scientific Council on Cardiomyopathies of the World Heart Federation is to review the considerable progress in our understanding of the etiopathogenesis, morbid anatomy, and clinical presentation of ARVD/C since it first was described in 1977. The present article focuses on important but still unanswered issues, mostly regarding risk stratification, clinical outcome, and management of affected patients. Because ARVD/C is relatively uncommon and any one center may have experience with only a few patients, an international registry is being established to accumulate information and enhance the numbers of patients that can be analyzed and thus answer pending questions. The registry also will facilitate pathological, molecular, and genetics research on the causes and pathogenesis of the ARVD/C. Furthermore, availability of an international database will enhance awareness of this largely unrecognized condition among the medical community. Physicians are encouraged to enroll patients in the International Registry of ARVD/C.  (+info)

Arrhythmogenic right ventricular cardiomyopathy with an initial manifestation of severe left ventricular impairment and normal contraction of the right ventricle. (5/272)

A case of arrhythmogenic right ventricular cardiomyopathy (ARVC) with an initial manifestation of severe impairment of the left ventricle (LV) and normal contraction of the right ventricle (RV) is presented. A 43-year-old man was admitted to hospital because of congestive heart failure following a common cold. The LV function was diffusely and severely hypokinetic. Coronary arteriogram revealed normal vessels. An endomyocardial biopsy specimen obtained from the RV septum revealed mild infiltration of lymphocytes with focal myocytes necrosis and so healing myocarditis was suspected. The specimen did not include any fatty replacement of myocytes. Since then, the patient suffered from recurrent congestive heart failure as well as nonsustained ventricular tachycardia and required frequent hospitalization. Progressive impairment, dilation, and thinning of both ventricles were observed on serial echocardiographic examinations. Although the RV gradually enlarged and became impaired, severe dilatation and impairment of the LV has always been predominant in the patient's clinical course. After medical follow-up for 10 years, he died suddenly of ventricular fibrillation and pump failure. The autopsy revealed extensive fibrofatty replacement of myocytes in both the ventricles, extending from the outer layer to the inner layer of myocardium in the RV and to the middle layer in the LV. These features were compatible with arrhythmogenic right ventricular cardiomyopathy or perimyocarditis, although only the rightsided bundle of the interventricular septum was completely replaced by fatty tissue, which can not be explained as a sequel of perimyocarditis. Moreover, apoptosis was present in the myocyte nuclei of the myocardial layers bordering the area of fatty replacement. Therefore, myocarditis may have triggered or accelerated the process of apoptosis leading to ARVC.  (+info)

Arrhythmogenic right ventricular dysplasia. An illustrated review highlighting developments in the diagnosis and management of this potentially fatal condition. (6/272)

Arrhythmogenic right ventricular dysplasia is an inherited, progressive condition. Characterised by fatty infiltration of the right ventricle, it frequently results in life threatening cardiac arrhythmias, and is one of the important causes of sudden cardiac death in the young. There are characteristic electrocardiographic and echocardiographic features that all physicians need to be aware of if we are to reduce these occurrences of premature death. Diagnosis with magnetic resonance imaging is discussed along with current treatment options.  (+info)

Left ventricular aneurysm without coronary artery disease, incidence and clinical features: clinical analysis of 11 cases. (7/272)

OBJECTIVE: To examine the incidence, underlying disease and clinical features of left ventricular aneurysm (LVA) not related to coronary artery occlusion. METHODS: Retrospective review of consecutive patients who underwent both left ventriculography and coronary angiography. PATIENTS: LVA was confirmed in 11 of 2,348 consecutive patients (0.47%). RESULTS: The location of LVA was mainly in the apical region (81.8%). In five of the 11 patients (45.5%), the underlying heart disease was hypertrophic cardiomyopathy (HCM), including 4 patients of dilated phase and one patient of midventricular type. The serial ECG changes from left ventricular hypertrophy to abnormal Q wave and endomyocardial biopsy were useful for the differential diagnosis of these cases against myocardial infarction. The underlying disease of the remaining patients was: myocarditis (2 patients), arrhythmogenic right ventricular dysplasia (1 patient), Chagas' disease (1 patient), glycogen storage disease (1 patient), and sarcoidosis (1 patient). Ventricular tachycardia appeared in 9 of 11 cases (81.8%) including 2 patients with sustained ventricular tachycardia. CONCLUSION: LVA formation without coronary artery disease was a rare phenomenon. The underlying disease was varied but the incidence of hypertrophic cardiomyopathy in the dilated phase was comparatively high. Ventricular tachycardia was a significant complication in these patients.  (+info)

No detection of enteroviral genome in the myocardium of patients with arrhythmogenic right ventricular cardiomyopathy. (8/272)

AIMS: Despite the evidence of familial occurrence, chromosomal gene mapping, and apoptosis as a mechanism of myocyte death, the aetiopathogenesis of arrhythmogenic right ventricular cardiomyopathy (ARVC) remains speculative. Because of the frequent histological finding of focal inflammatory infiltrates, the hypothesis of an infective myocarditis aetiology has been put forward. The aim of this investigation was to test this hypothesis. The presence of enteroviruses was investigated by a highly sensitive and specific molecular technique. METHODS: Endomyocardial tissue samples from 20 patients with ARVC (11 male, nine female; mean age, 40 years; SD, 16) and 20 control subjects with other cardiac diseases were analysed using reverse transcription and nested polymerase chain reaction (PCR). Myocardial samples obtained from four patients with enteroviral myocarditis and coxsackie B3 virus infected cells were used as positive controls. RESULTS: Endomyocardial biopsy was diagnostic for ARVC in all patients: myocardial atrophy was seen, with less than 45% residual myocytes. Foci of inflammatory infiltrates were seen in four biopsies, and the cells were identified by immunohistochemistry as mainly T cells. All samples, from both patients with ARVC and subjects with other cardiac diseases, were negative for enteroviral genome by means of nested PCR. CONCLUSION: These findings indicate that enteroviruses are not involved in the aetio-pathogenesis of ARVC. Future molecular studies should investigate the presence of other infective agents, as well as their possible role in triggering apoptosis.  (+info)

TY - JOUR. T1 - Arrhythmogenic right ventricular dysplasia/cardiomyopathy - Three decades of progress. AU - Calkins, Hugh. PY - 2015. Y1 - 2015. N2 - Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is a rare, inherited cardiomyopathy characterized by ventricular arrhythmias, sudden cardiac death, and right ventricular dysfunction. Since the first major description of this disease, much has been learned about ARVD/C. One of the main breakthroughs was the discovery that mutations in desmosomal proteins are the most frequent genetic basis of ARVD/C. Today, genetic testing plays an important role in both the diagnosis of ARVD/C and cascade family screening. Much has also been learned concerning the optimal approaches to diagnosis. The 2010 Task Force Diagnostic criteria for ARVD/C represent the standard for diagnosis today. We have also learned much about the importance of proband status and the 24-h PVC count to assess sudden death risk, and the importance of exercise both in the ...
The disease was first described by Giovanni Maria Lancisi in 1736, who in his book De Motu Cordis et Aneurysmatibus reported a family with disease recurrence in four generations: the affected members presented with palpitations, heart failure, dilation and aneurysms of the RV and sudden death [9].. Dalla Volta et al. in 1961 reported a patient with auricularization of the RV pressure curve, emphasizing the peculiar hemodynamic picture of this non-ischemic heart muscle disease with RV behaving like an atrium [10]. However, we had to wait until the 80s to find the first clinical and pathologic series of patients with ARVC/D reported by Drs Marcus, Nava and Thiene [1-3].. Marcus et al. in 1982 reported the disease in adults, first emphasizing the origin of arrhythmias from the RV and the histopathological substrate consisting of fibro-fatty replacement of the RV free wall, accounting for epsilon wave and ventricular arrhythmias of RV origin with left bundle branch block (LBBB) morphology ...
We read with interest the paper by Marcus et al. (1) published in the May 14, 2013 issue of the Journal. The authors brought to light the complex nature of clinical genetics in arrhythmogenic right ventricular cardiomyopathy (ARVC) patients. Overall, this paper provides an important review of the current state of clinical genetic testing for this rare condition. We applaud the authors for their confirmation of the Heart Rhythm Society/European Heart Rhythm Association guidelines (2) in recommending genetic counseling when ordering genetic testing in this and other cardiomyopathies.. The Johns Hopkins arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) program was established in 1999 with 3 goals: 1) to educate patients and physicians about ARVD/C; 2) to evaluate and manage patients with known or suspected ARVD/C; and 3) to contribute to the body of literature regarding this condition. The program has facilitated the clinical evaluation of over 1,140 patients and follows over 250 ...

̣̣̣̺ Arrhythmogenic right ventricular dysplasia (ARVD), also called arrhythmogenic right ventricular cardiomyopathy (ARVC) or arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C), is an inherited heart disease.Wikipedia ARVD is caused by genetic defects of the parts of heart muscle (also called myocardium or cardiac muscle) known as desmosomes, areas on the surface of heart muscle cells which link the cells together. The desmosomes are composed of several proteins, and many of those proteins can have harmful mutations. The disease is a type of nonischemic cardiomyopathy that involves primarily the right ventricle. It is characterized by hypokinetic areas involving the free wall of the right ventricle, with fibrofatty replacement of the right ventricular myocardium, with associated arrhythmias originating in the right ventricle. ARVD can be found in association with diffuse palmoplantar keratoderma, and woolly hair, in a autosomal recessive condition called Naxos disease, ...
Also known as arrhythmogenic right ventricular cardiomyopathy. ARVD stands for Arrhythmogenic Right Ventricular Dysplasia. Arrhythmogenic means causing an arrhythmia. The right ventricle is the chamber of the heart that is affected and dysplasia means there is an abnormality of the structure. The right ventricle is dilated and contracts poorly. As a result, the ability of the heart to pump blood is usually weakened. Patients with ARVD often have arrhythmias (abnormal heart rhythms), which can increase the risk of sudden cardiac arrest or death.. ARVD is a specific type of cardiomyopathy (a disorder of the cardiac muscle).. Simply put, ARVD is a genetic, progressive heart condition in which the muscle of the right ventricle is replaced by fat and fibrosis, which causes abnormal heart rhythms. ARVD is estimated to affect one in 5,000 people. The disease can affect both men and women. Although it is a relatively uncommon cause of sudden cardiac death, it accounts for up to one fifth of sudden ...

Arrhythmogenic right ventricular (RV) dysplasia/cardiomyopathy (ARVD/C) is an inherited cardiomyopathy characterized histologically by fibro-fatty myocardial replacement of the RV and clinically by ventricular arrhythmias and RV dysfunction (1,2). Patients with ARVD/C typically present in their mid-teens to mid-forties with symptomatic ventricular tachycardia (VT) of a left bundle branch block morphology (3). Sudden cardiac death may be the first manifestation of the disease (3-5). Clinical diagnosis is based on diagnostic criteria proposed by the International Task Force of the European Society of Cardiology and International Society and Federation of Cardiology that take into account arrhythmic, electrocardiographic, structural, and histopathologic abnormalities, as well as family history (6).. Arrhythmogenic RV dysplasia/cardiomyopathy is a genetic disorder transmitted with reduced penetrance and variable expressivity. To date, 6 genes have been identified with mutations causing ARVD/C. Both ...

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited heart muscle disease that may result in arrhythmia, heart failure, and sudden death. The hallmark pathological findings are progressive myocyte loss and fibrofatty replacement, with a predilection for the right ventricle. A number of genetic studies have identified mutations in various components of the cardiac desmosome that have important roles in the pathogenesis of ARVC. Disruption of desmosomal function by defective proteins might lead to death of myocytes under mechanical stress. The myocardial injury may be accompanied by inflammation. Since regeneration of cardiac myocytes is limited, repair by fibrofatty replacement occurs. Several studies have implicated that desmosome dysfunction results in the delocalization and nuclear translocation of plakoglobin. As a result, competition between plakoglobin and beta-catenin will lead to the inhibition of Wnt/beta-catenin signaling, resulting in a shift from a myocyte fate ...

Transvenous pacemaker or implantable cardio-verter defibrillator (ICD) implantation procedures are usually performed under local anesthetic, and prilocaine is the most common agent to be used. The data regarding methemoglobinemia after cardiac device implantation are scarce. Thus, presently described is the case of a 47-year-old female patient with arrhythmogenic right ventricular cardiomyopathy/dysplasia who underwent ICD implantation for secondary prophylaxis and developed cyanosis as a result of prilocaine-associated methemoglobinemia. Prilocaine was administered during the procedure. To our knowledge, this is the second case in the literature presenting methemoglobinemia due to local anesthetic after transvenous cardiac device implantation. ...

Aims: Differentiation between early-phase arrhythmogenic right ventricular cardiomyopathy (ARVC) and right ventricular outflow tract (RVOT)-ventricular tachycardia (VT) can be challenging, and correct diagnosis is important. We compared electrocardiogram (ECG) parameters and morphological right ventricular (RV) abnormalities and investigated if ECG and cardiac imaging can help to discriminate early-phase ARVC from RVOT-VT patients. Methods and results: We included 44 consecutive RVOT-VT (47+14 years) and 121 ARVC patients (42+17 years). Of the ARVC patients, 77 had definite ARVC and 44 had early-phase ARVC disease. All underwent clinical examination, ECG, and Holter monitoring. Frequency of premature ventricular complexes (PVC) was expressed as percent per total beats/24 h (%PVC), and PVC configuration was recorded. By echocardiography, we assessed indexed RV basal diameter (RVD), indexed RVOT diameter, and RV and left ventricular (LV) function. RV mechanical dispersion (RVMD), reflecting RV ...
Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited myocardial disease characterized by fibrofatty replacement and ventricular arrhythmias. ARVC is believed to be a disease of the young, with most cases being diagnosed before the age of 40 years. We report here a case of newly diagnosed ARVC in an octogenarian associated with a pathogenic variant in the plakophilin 2 gene (PKP2). An 80-year-old Japanese man was referred for sustained ventricular tachycardia. His baseline electrocardiogram showed negative T waves in V1-V4. Right ventriculography showed right ventricular aneurysm. Because this case met three major criteria, ARVC was diagnosed. He was successfully treated with radiofrequency ablation and oral amiodarone. Genetic analysis identified an insertion mutation in exon 8 of PKP2 (1725_1728dupGATG), which caused a frameshift and premature termination of translation (R577DfsX5). To the best of our knowledge, this is the first report of newly diagnosed ARVC in an octogenarian

The differences between ARVD patients and normals were large for the filtered QRS duration (FQRSd) (146.2±18.9 vs. 91.8±4.1ms, P,000001), the late potential duration (LPd) (83.5±23.3 ms vs. 23.6±4.6ms, P, 0.00001), the LPd/ FQRSd ratio (53.9± 10.1% vs. 25.8±5.1%, P ,0.00001), the filtered QRS amplitude (234.0±61.1μV vs. 429±942 fiV, P ,0001), and the root mean square voltage of the signals in the terminal 40 and 50 ms of the FQRS (RMS40 and RMS50) (18.4± 10.0μV vs. 118.4±49.8p.V, P,0.0005 and 27.9± 19.2μV vs. 217.0±66.3fiV, P,0000002). RMS50 ,40μV discriminated best between ARVD and normals (81% sensitivity and 100% specificity). The right-sided predominance of the abnormalities in ARVD was demonstrated by the significantly longer FQRSd and LPd, and the higher ratio LPd/FQRSd in right than in left precordial leads. The ...
Arrhythmogenic Right Ventricular Dysplasia is when the muscle tissue in the right ventricle of the heart dies and is replaced with fat and/or fibrous tissue thus disrupting the electrical signals of the heart and causes arrhythmias. This is the forum for discussing anything related to this health condition
Author(s): Scheinman, Melvin; Hoffmayer, KS; Scheinman, MM | Abstract: Ventricular arrhythmias in patients with ARVD/C are common. Differentiation between idiopathic VT and ARVD is of utmost importance. Baseline sinus rhythm electrocardiography as well as electrocar- diographic differences during ventricular arrhythmias (VT o
Right ventricular dysplasia is characterized by an abnormality in the development of part of the right ventricular musculature. Patients with right ventricular dysplasia may present with ventricular tachycardia, supraventricular arrhythmias, right-heart failure or asymptomatic cardiomegaly. Twenty-two adult patients with right ventricular dysplasia who had recurrent ventricular tachycardia were seen during a 7-year period. The male/female ratio was 2.7:1. The mean age at the time of hospitalization was 39 years. All but one of the patients had ventricular tachycardia of a left bundle branch block configuration. With few exceptions, the T waves were inverted over the right precordial leads. The heart was usually enlarged and the pulmonary vasculature was usually normal. In six patients who had two-dimensional echocardiograms, all showed increased right ventricular diastolic dimensions. All patients had right ventricular angiography; the diagnosis of right ventricular dysplasia was substantiated ...
Background: The Ser358Leu mutation in TMEM43, encoding an inner nuclear membrane protein, has been implicated in arrhythmogenic right ventricular cardiomyopathy (ARVC). The pathogenetic mechanisms of this mutation are poorly understood. Methods: To determine the frequency of TMEM43 mutations as a cause of ARVC, we screened 11 ARVC families for mutations in TMEM43 and five desmosomal genes previously implicated in the disease. Functional studies were performed in COS-7 cells transfected with wildtype, mutant, and 1:2 wildtype:mutant TMEM43 to determine the effect of the Ser358Leu mutation on the stability and cellular localization of TMEM43 and other nuclear envelope and desmosomal proteins, assessed by solubility assays and immunofluorescence imaging. mRNA expression was assessed of genes potentially affected by dysfunction of the nuclear lamina. Results: Three novel mutations in previously documented desmosomal genes, but no mutations in TMEM43, were identified. COS-7 cells transfected with ...
AIMS: Recent immunohistochemical studies observed the loss of plakoglobin (PG) from the intercalated disc (ID) as a hallmark of arrhythmogenic right ventricular cardiomyopathy (ARVC), suggesting a final common pathway for this disease. However, the underlying molecular processes are poorly understood. METHODS AND RESULTS: We have identified novel mutations in the desmosomal cadherin desmocollin 2 (DSC2 R203C, L229X, T275M, and G371fsX378). The two missense mutations (DSC2 R203C and T275M) have been functionally characterized, together with a previously reported frameshift variant (DSC2 A897fsX900), to examine their pathogenic potential towards PGs functions at the ID. The three mutant proteins were transiently expressed in various cellular systems and assayed for expression, processing, localization, and binding to other desmosomal components in comparison to wild-type DSC2a protein. The two missense mutations showed defects in proteolytic cleavage, a process which is required for the functional
Definition, Etiology, PathogenesisTop. Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a genetic disease involving mainly the right ventricle. It is caused by the gradual replacement of myocardial fibers by fatty and fibrous tissue, particularly in the right ventricular inflow, outflow, and apex, which leads to a propensity to ventricular arrhythmias and sudden cardiac death. Morphologic and functional changes can also occur in the left ventricle (LV), producing a phenotype similar to dilated cardiomyopathy. Causes: Gene mutations, which are usually autosomal dominant.. Clinical Features and Natural HistoryTop. 1. History: ARVC usually presents in young adult men. The first symptom is a brief loss of consciousness caused by ventricular arrhythmia. Sudden cardiac death may occur.. 2. Risk factors of sudden cardiac death include a young age, history of syncope, cardiac arrest or hemodynamically significant ventricular tachycardia, LV involvement, significant right ventricular damage, ...
ARVC or arrhythmogenic right ventricular cardiomyopathy is a rare illness. The occurrence of the same makes it impossible for an individual to recover completely.
Conclusions and implications Acute ventricular cardiomyopathy is a common complication of severe sepsis and is difficult to diagnose using standard invasive cardiac output devices commonly used within critical care areas. Trans thoracic echocardiography presents a point of care diagnostic modality that allows rapid, repeatable, reliable assessment of independent ventricular function. Low cardiac output states seen with acute dilated right ventricular cardiomyopathy appear to show little benefit from fluid boluses and poor response to standard pharmacological strategies for septic shock. In the two patients requiring invasive ventilation, death followed within 72 h of diagnosis of right ventricular cardiomyopathy. Surveillance scanning for a impaired and/or dilated right ventricle may allow earlier detection and exploration of alternative treatment strategies. Respiratory failure in severe septic shock associated with right ventricular cardiomyopathy appears to confer a significant increased ...
Arrhythmogenic right ventricular dysplasia (or ARVD) is a disease of the heart muscle. In this disease, fatty fibrous tissue replaces normal heart muscle. This interrupts normal electrical signals in the heart and may cause irregular and potentially life-threatening heart rhythms. The heart also becomes weaker over time leading to heart failure.
Studying arrhythmogenic right ventricular dysplasia with patient-specific iPSCs. Modelling genetic disorders using induced pluripotent stem cells (iPSCs) is an emerging tool for researchers; however cells derived from iPSCs, such as cardiomyocytes (CMs), have not yet been qualified as useful models of adult disease phenotypes. Now researchers from the group of Huei-Sheng Vincent Chen at the Sanford-Burnham Medical Research Institute, California, USA have studied the inherited heart disease arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) (Calkins and Marcus) an inherited heart disease characterized by pathological fatty infiltration and cardiomyocyte loss in the right ventricle. From patient-specific mutation bearing fibroblasts they generated iPSCs and subsequently iPSC-CMs; finding that induction of adult-like metabolism has a critical role in establishing an adult-onset disease model (Kim et al).. Using fibroblasts taken from a patient with clinical ARVD/C and a homozygous ...
Arrhythmogenic right ventricular dysplasia (ARVD) is a hereditary cardiomyopathy that causes sudden death in the young. We found a line of mice with inherited right ventricular dysplasia (RVD) caused by a mutation of the gene laminin receptor 1 (Lamr1). This locus contained an intron-processed retroposon that was transcribed in the mice with RVD. Introduction of a mutated Lamr1 gene into normal mice by breeding or by direct injection caused susceptibility to RVD, which was similar to that seen in the RVD mice. An in vitro study of cardiomyocytes expressing the product of mutated Lamr1 showed early cell death accompanied by alteration of the chromatin architecture. We found that heterochromatin protein 1 (HP1) bound specifically to mutant LAMR1. HP1 is a dynamic regulator of heterochromatin sites, suggesting that mutant LAMR1 impairs a crucial process of transcriptional regulation. Indeed, mutant LAMR1 caused specific changes to gene expression in cardiomyocytes, as detected by gene chip analysis. Thus,
Arrhythmogenic cardiomyopathy (AC) is a hereditary disorder characterized by degeneration of cardiac myocytes and their subsequent replacement by fat and fibrous tissue primarily in the right ventricle. Our study aimed to systematically evaluate the impact of significant demographic, clinical, electrocardiographic, and echocardiographic factors in arrhythmic events in AC patients. MEDLINE and Cochrane library databases were manually searched without year or language restriction or any other limits until July 31, 2017. A pooled odds ratio with 95% confidence intervals was calculated for each of the risk factors. Our search retrieved 26 studies (n = 2680 patients, mean age: 37.9 years old, males: 51.9%) which were included in the quantitative synthesis. The most reliable predicting factors/parameters are the following: (1) male gender, (2) presyncope, (3) left ventricular dysfunction, (4) T-wave inversions in inferior leads, (5) proband status, (6) late potentials, (7) syncope, (8) inducibility at ...
Myocyte death occurs in many inherited and acquired cardiomyopathies, including arrhythmogenic cardiomyopathy (ACM), a genetic heart disease plagued by the prevalence of sudden cardiac death. Individuals with ACM and harboring pathogenic desmosomal variants, such as desmoglein-2 (DSG2), often show myocyte necrosis with progression to exercise-associated heart failure. Here, we showed that homozygous Dsg2 mutant mice (Dsg2mut/mut), a model of ACM, die prematurely during swimming and display myocardial dysfunction and necrosis. We detected calcium (Ca2+) overload in Dsg2mut/mut hearts, which induced calpain-1 (CAPN1) activation, association of CAPN1 with mitochondria, and CAPN1-induced cleavage of mitochondrial-bound apoptosis-inducing factor (AIF). Cleaved AIF translocated to the myocyte nucleus triggering large-scale DNA fragmentation and cell death, an effect potentiated by mitochondrial-driven AIF oxidation. Posttranslational oxidation of AIF cysteine residues was due, in part, to a depleted ...
Mutations in the gene for desmoplakin (DSP) may cause arrhythmogenic right ventricular cardiomyopathy (ARVC) and Carvajal syndrome (CS). Desmoplakin is part of all desmosomes, which are abundantly expressed in both myocardial and epidermal tissue and serve as intercellular mechanical junctions. This study aimed to investigate protein expression in myocardial and epidermal tissue of ARVC and CS patients carrying DSP mutations in order to elucidate potential molecular disease mechanisms. Genetic investigations identified three ARVC patients carrying different heterozygous DSP mutations in addition to a homozygous DSP mutation in a CS patient. The protein expression of DSP in mutation carriers was evaluated in biopsies from myocardial and epidermal tissue by immunohistochemistry. Keratinocyte cultures were established from skin biopsies of mutation carriers and characterized by reverse transcriptase polymerase chain reaction, western blotting, and protein mass spectrometry. The results showed that ...
BACKGROUND: Previous studies suggested that electrical abnormalities precede overt structural disease in arrhythmogenic right ventricular cardiomyopathy (ARVC). Abnormal RV deformation has been reported in early ARVC without structural abnormalities. The pathophysiological mechanisms underlying these abnormalities remain unknown. OBJECTIVES: The authors used imaging and computer simulation to differentiate electrical from mechanical ... read more tissue substrates among ARVC clinical stages. METHODS: ARVC desmosomal mutation carriers (n = 84) were evaluated by electrocardiography (ECG), Holter monitoring, late-enhancement cardiac magnetic resonance imaging, and echocardiographic RV deformation imaging. Subjects were categorized based on the presence of 2010 International Task Force criteria: 1) subclinical stage (n = 21); 2) electrical stage (n = 15); and 3) structural stage (n = 48). Late enhancement was not present in any subclinical or electrical stage subjects. RESULTS: Three distinctive ...
Boxer cardiomyopathy (also known as Boxer arrhythmogenic right ventricular cardiomyopathy) is a disease of the myocardium primarily affecting Boxer dogs. It is characterized by the development of ventricular tachyarrhythmias, resulting in syncope and sudden cardiac death. Myocardial failure and congestive heart failure are uncommon manifestations of the disease. Boxer cardiomyopathy shares striking similarities to a human myocardial disease called arrhythmogenic right ventricular cardiomyopathy (ARVC). On histopathology, the disease is characterized by the progressive replacement of ventricular myocardium (primarily right ventricular myocardium) with fatty or fibro-fatty tissue. Clinically, the disease is characterized by the development of ventricular tachyarrhythmias, including ventricular tachycardia and ventricular fibrillation. Affected dogs are at risk of syncope and sudden cardiac death. Boxer cardiomyopathy is a genetic disease inherited in an autosomal dominant pattern. The ...

The patient received a single-chamber implantable cardioverter-defibrillator (ICD), which was implanted without complications.. The patient was advised to limit physical exertion and was prescribed beta-blockers (bisoprolol 2.5 mg daily) in addition to his usual medication.. He remained asymptomatic and tolerated the ICD well. Genetic study and electrocardiographic and echocardiographic monitoring have been recommended for his offspring.1,2. DiscussionEpidemiology. There are limited epidemiologic data on ARVD. Its prevalence in the general population is between 1/2000 and 1/5000, with males being affected more often than females (3:1). Its incidence ranges between 1/1000 and 1/50 000, with considerable geographic variability.3-5. In most cases (80%) ARVD is diagnosed before the age of 40. Worldwide, it is identified as the cause of sudden cardiac death in young adults in 5-11% of cases. In a study in northern Italy it was the leading cause (22.4%) of sudden death in young athletes.6. ARVD should ...
Fifteen patients with right ventricular tachycardia without evidence of coronary artery disease or dilated or hypertrophic cardiomyopathy were evaluated, by means of electrophysiologic study and right ventricular endomyocardial biopsy. Six cases were
Our data showed that female sex was a risk factor of HF-related clinical deterioration and death in ARVC. HF is an important determinant of clinical prognosis in ARVC patients. In the previous study of the natural history of 130 cases with ARVC, Hulot et al. (35) reported that 24 patients died during the follow-up period and that 59% of these deaths were related to progressive HF. In our study, the incidences of HF death and heart transplantation due to HF were significantly higher in female than in male patients. Furthermore, female sex was an independent predictor of HF-related death or heart transplantation.. One possible mechanism for the sex-based differences is related to the reaction to volume overload and influence of thoracic size. Fitzpatrick et al. (36) analyzed a series of 266 LV assist device recipients and found that a biventricular assist device was required more commonly for female patients (p = 0.001) and for those with smaller BSA (p = 0.003). Ochiai et al. (37) also reported ...
A 46-year-old white woman presented to the emergency department with hemodynamically stable sustained ventricular tachycardia (VT). She was chemically cardioverted with lidocaine. Her electrocardiogram, showing sinus rhythm, was unremarkable, and serial cardiac enzyme tests excluded myocardial infarction. A signal-averaged electrocardiogram was abnormal, with a filtered QRS duration of 187 milliseconds. Echocardiography showed normal left and right ventricular systolic function but revealed diastolic dysfunction of the left ventricle. Electrophysiologic testing revealed easily inducible sustained VT of 4 distinct morphologies. A diagnosis of possible arrhythmogenic right ventricular dysplasia was made based on the signal-averaged electrocardiographic and electrophysiologic findings. Cardiac magnetic resonance imaging showed no evidence of arrhythmogenic right ventricular dysplasia, however. An endomyocardial biopsy revealed noncaseating granulomas consistent with sarcoidosis. This case ...
Variant summary: PKP2 c.14delG (p.Gly5AlafsX34) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Truncations downstream of this position have been classified as pathogenic by our laboratory (e.g., p.Arg79X and p.Gln133X). The variant was absent in 30714 control chromosomes. c.14delG has been reported in the literature in one individual affected with Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C). To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. One clinical diagnostic laboratory has submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation and classified the variant as pathogenic. Another clinical diagnostic laboratory has submitted assessment for this variant to ClinVar before 2014 without evidence ...

A case of sudden and unexpected death during physical aggression with trauma is reported. Injury caused only the fracture of the nasal bone and no important findings from autopsy could justify death. Only histological examination shows focal fibro-fatty infiltrates in the right ventricular myocardium. The relationship is discussed between emotional stress and death in subjects not suffering from clear arrhythmogenic right ventricular cardiomyopathy (ARVC) but with histopathological focal evidence. According to the authors, histological findings are however important, because they can explain arrhythmias by a re-entrant mechanism. The highest caution is suggested in the evaluation of emotional deaths like this, because the relationship between emotional stress and arrhythmias cannot be proved but only suspected, and can be accepted when a chronological link between the 2 events is present.. ...

Appropriate and Inappropriate Implantable Cardioverter Defibrillators Therapies in Arrhythmogenic Right Ventricular Cardiomyopathy/Dysplasia Patients
Introduction -. Abnormalities of desmosomes, more specifically mutations in the desmoplakin (DSP) gene, have been shown to cause not only arrhythmogenic right ventricular cardiomyopathy (ARVC) but also sick sinus syndrome (SSS) as well. Although various ARVC overlap syndromes have been described, its association with sinus node dysfunction is not documented. In this report, we describe an autosomal dominant missense mutation in the DSP gene in a proband with sick sinus syndrome and features of ARVC on cardiac MRI.. Clinical case -. A 70 year old man presented with a recurrent episodes of syncope, that were historically suggestive of an arrhythmic etiology. He had a history of systemic hypertension which was under adequate control with ACE inhibitors. His 2D Echocardiogram (ECHO) revealed a structurally normal heart. During his evaluation of syncope, his baseline electrocardiogram (ECG), head up tilt test, brain imaging, and electroencephalography were non-contributory. Cardiac MRI(CMR) ...

This gene encodes a secreted ligand of the TGF-beta (transforming growth factor-beta) superfamily of proteins. Ligands of this family bind various TGF-beta receptors leading to recruitment and activation of SMAD family transcription factors that regulate gene expression. The encoded preproprotein is proteolytically processed to generate a latency-associated peptide (LAP) and a mature peptide, and is found in either a latent form composed of a mature peptide homodimer, a LAP homodimer, and a latent TGF-beta binding protein, or in an active form consisting solely of the mature peptide homodimer. The mature peptide may also form heterodimers with other TGF-beta family members. This protein is involved in embryogenesis and cell differentiation, and may play a role in wound healing. Mutations in this gene are a cause of aortic aneurysms and dissections, as well as familial arrhythmogenic right ventricular dysplasia 1. [provided by RefSeq, Aug 2016 ...

Desmosomes are macromolecular, dynamic and adaptable complexes that connect intermediate filaments of neighboring cells in a variety of tissues, generating a large mechanically resilient structure. The importance of maintaining desmosome homeostasis for tissue integrity and optimal organ function has been revealed through the identification of desmosome-associated disorders and mechanistic studies into desmosome regulation. This thesis focuses on inherited skin and heart conditions linked to mutations in desmosomal genes or in genes believed to be implicated in desmosome regulation. Part of this thesis is focused on the molecular analysis and identification of novel desmosomal mutations in patients clinically diagnosed with Arrhythmogenic Right Ventricular Cardiomyopathy, and the genetic diagnosis of patients with hypotrichosis, hypotrichosis and PPK or acral peeling skin syndrome. Patients were analysed using a number of different genetic techniques including custom capture array, HaloPlex ...
Ca2+ release from the sarcoplasmic reticulum mediated by the cardiac ryanodine receptor (RyR2) is a fundamental event in cardiac muscle contraction. RyR2 mutations suggested to cause defective Ca2+ channel function have recently been identified in catecholaminergic polymorphic ventricular tachycardia (CPVT) and arrhythmogenic right ventricular dysplasia (ARVD) affected individuals. We report expression of three CPVT-linked human RyR2 (hRyR2) mutations (S2246L, N4104K, and R4497C) in HL-1 cardiomyocytes displaying correct targeting to the endoplasmic reticulum. N4104K also localized to the Golgi apparatus. Phenotypic characteristics including intracellular Ca2+ handling, proliferation, viability, RyR2:FKBP12.6 interaction, and beat rate in resting HL-1 cells expressing mutant hRyR2 were indistinguishable from wild-type (WT) hRyR2. However, Ca2+ release was augmented in cells expressing mutant hRyR2 after RyR activation (caffeine and 4-chloro-m-cresol) or. ...

Background There are still ambiguities existing in regard to left ventricular non-compaction (LVNC) diagnostic imaging. The aim of our study was to analyze diagnostic potential of late gadolinium enhancement (LGE) and ventricle geometry in patients with LVNC and controls. Methods Data on cardiac magnetic resonance imaging (CMR) studies for LVNC were reassessed from the hospitals database (3.75 years; n=1975 exams). Matching sample of controls included cases with no structural heart disease, hypertrophic or dilative cardiomyopathy, arrhythmogenic right ventricular dysplasia or subacute myocarditis. Eccentricity of the left ventricle was measured at end diastole in the region with pronounced NC and maximal to minimal ratio (MaxMinEDDR) was calculated. Results Study included 255 patients referred for CMR, 100 (39.2%) with LVNC (prevalence in the studied period 5.01%) and 155 (60.8%) controls. Existing LGE had sensitivity of 52.5% (95%-CI:42.3-62.5), specificity of 80.4% (95%-CI:73.2-86.5) for ...
Definition of arrhythmogenic right ventricular. Provided by Stedmans medical dictionary and Drugs.com. Includes medical terms and definitions.
Genetic testing for up to 105 genes that cause inherited cardiomyopathy, including arrhythmogenic right ventricular cardiomyopathy (ARVC), dilated cardiomyopathy (DCM), hypertrophic cardiomyopathy (HCM), left ventricular noncompaction (LVNC), and some syndromic causes of cardiomyopathy.
Patients with heart failure can roughly be divided into two groups: those with ventricular dysfunction due to ischaemia and those with a non-ischaemic heart disease. Most of the different forms of cardiomyopathy in the last group can have a distinct cause like hypertension or a valvular heart disease. However in an important subset of these no such cause is identified thereby obtaining the classification idiopathic cardiomyopathy. The familial character of these different forms of idiopathic cardiomyopathy has been recognized in many studies.. Four categories of disease are distinghuised and the basis of haemodynamical and morphological characteristics: hypertrophic cardiomyopathy (HCM), dilated cardiomyopathy (DCM), restrictive cardiomyopathy (RCM) and arrhythmogenic right ventricular cardiomyopathy (ARVC).. HCM is characterised by (usually asymmetric) left ventricular hypertrophy. In myocardial biopsies, myofibrillar disarray and myocyte hypertrophy is seen. Arrhythmias and premature sudden ...
Background: Epicardial catheter ablation has been shown to be an effective strategy for treating ventricular arrhythmias (VA). We investigated the efficacy and safety from a tertiary referral center in Taiwan. Methods: From 2010 to 2016, patients undergoing epicardial ablation for VAs were consecutively enrolled. The clinical characteristics, disease entity, electrophysiological studies, and ablation outcome were extracted for further analysis. Results: A total of 80 patients were eligible, including 34 patients for arrhythmogenic right ventricular cardiomyopathy (ARVC), 16 for Brugada syndrome (BrS), 13 for idiopathic VAs, 11 for idiopathic dilated cardiomyopathy (IDCM), 2 for ischemic cardiomyopathy, and 4 for other nonischemic cardiomyopathies (NICM ...
Purpose T wave inversion (TWI) is the electrical hallmark of cardiac conditions such as hypertrophic cardiomyopathy (HCM) or arrhythmogenic right ventricular cardiomyopathy (ARVC), which may be the substrate for sudden cardiac death in the young athlete. Such repolarization anomalies can feature on the ECG of an apparently healthy athlete and pose major diagnostic dilemmas in sports cardiology, as regular, prolonged high intensity, physical activity is associated with such repolarization changes. Athletes themselves are reluctant to detrain during the season, which makes interpreting any reversible effects of exercise on the ECG more difficult. This study aimed to investigate the effect of detraining on TWI in athletes. ...
Amongst adult cats, myocardial disease (cardiomyopathy) is the most common form of heart disease. Hypertrophic cardiomyopathy (HCM) is identified in over 60% of cardiomyopathic cats, with the rest attributable to dilated cardiomyopathy, restrictive cardiomyopathy (endomyocardial or myocardial), arrhythmogenic right ventricular cardiomyopathy, and unclassified cardiomyopathy.. The criteria by which each form of cardiomyopathy is defined are based on echocardiographically-derived parameters; however, there is some overlap between categories, which results in controversy over the classification of some individuals. Of greater importance for these individuals is correct identification of the type of functional abnormality (e.g., systolic dysfunction, diastolic dysfunction, or both), as this has direct implications for patient management.. While pathophysiology of the feline cardiomyopathies differs, affected cats are at risk for the same three adverse sequelae: congestive failure, thromboembolic ...
Figure caption and citation for the preceding image starts]: Sustained (monomorphic) ventricular tachycardia From the collection of Prof Sei Iwai; used with permission [Citation ends]. VT is defined as a wide complex tachycardia (QRS 120 milliseconds or greater) that originates from one of the ventricles, and is not due to aberrant conduction (e.g., from bundle branch block), at a rate of 100 bpm or greater. Idiopathic VT occurs in the absence of apparent structural heart disease (e.g., prior MI, active ischemia, cardiomyopathy, valvular disease, arrhythmogenic right ventricular cardiomyopathy, left ventricular noncompaction, or other disorders of the myocardium), known channelopathy (e.g., long QT syndrome, Brugada syndrome, catecholaminergic polymorphic VT, short QT syndrome), drug toxicity, or electrolyte imbalance. VT can be described as monomorphic or polymorphic. Torsades de pointes is a polymorphic VT with a characteristic twisting morphology occurring in the setting of QT interval ...

Mutations in the DES gene coding for the intermediate filament protein desmin may cause skeletal and cardiac myopathies, which are frequently characterized by cytoplasmic aggregates of desmin and associated proteins at the cellular level. By atomic force microscopy, we demonstrated filament formation defects of desmin mutants, associated with arrhythmogenic right ventricular cardiomyopathy. To understand the pathogenesis of this disease, it is essential to analyze desmin filament structures under conditions in which both healthy and mutant desmin are expressed at equimolar levels mimicking an in vivo situation. Here, we applied dual color photoactivation localization microscopy using photoactivatable fluorescent proteins genetically fused to desmin and characterized the heterozygous status in living cells lacking endogenous desmin. In addition, we applied fluorescence resonance energy transfer to unravel short distance structural patterns of desmin mutants in filaments. For the first time, we ...
