Cardiomyopathy, Hypertrophic
A form of CARDIAC MUSCLE disease, characterized by left and/or right ventricular hypertrophy (HYPERTROPHY, LEFT VENTRICULAR; HYPERTROPHY, RIGHT VENTRICULAR), frequent asymmetrical involvement of the HEART SEPTUM, and normal or reduced left ventricular volume. Risk factors include HYPERTENSION; AORTIC STENOSIS; and gene MUTATION; (FAMILIAL HYPERTROPHIC CARDIOMYOPATHY).
Hypertrophy, Left Ventricular
Enlargement of the LEFT VENTRICLE of the heart. This increase in ventricular mass is attributed to sustained abnormal pressure or volume loads and is a contributor to cardiovascular morbidity and mortality.
Cardiomyopathy, Dilated
A form of CARDIAC MUSCLE disease that is characterized by ventricular dilation, VENTRICULAR DYSFUNCTION, and HEART FAILURE. Risk factors include SMOKING; ALCOHOL DRINKING; HYPERTENSION; INFECTION; PREGNANCY; and mutations in the LMNA gene encoding LAMIN TYPE A, a NUCLEAR LAMINA protein.
Gadolinium
Gadolinium. An element of the rare earth family of metals. It has the atomic symbol Gd, atomic number 64, and atomic weight 157.25. Its oxide is used in the control rods of some nuclear reactors.
Death, Sudden, Cardiac
Unexpected rapid natural death due to cardiovascular collapse within one hour of initial symptoms. It is usually caused by the worsening of existing heart diseases. The sudden onset of symptoms, such as CHEST PAIN and CARDIAC ARRHYTHMIAS, particularly VENTRICULAR TACHYCARDIA, can lead to the loss of consciousness and cardiac arrest followed by biological death. (from Braunwald's Heart Disease: A Textbook of Cardiovascular Medicine, 7th ed., 2005)
Magnetic Resonance Imaging, Cine
A type of imaging technique used primarily in the field of cardiology. By coordinating the fast gradient-echo MRI sequence with retrospective ECG-gating, numerous short time frames evenly spaced in the cardiac cycle are produced. These images are laced together in a cinematic display so that wall motion of the ventricles, valve motion, and blood flow patterns in the heart and great vessels can be visualized.
Cardiomyopathy, Hypertrophic, Familial
An autosomal dominant inherited form of HYPERTROPHIC CARDIOMYOPATHY. It results from any of more than 50 mutations involving genes encoding contractile proteins such as VENTRICULAR MYOSINS; cardiac TROPONIN T; ALPHA-TROPOMYOSIN.
Fatty Acids
Organic, monobasic acids derived from hydrocarbons by the equivalent of oxidation of a methyl group to an alcohol, aldehyde, and then acid. Fatty acids are saturated and unsaturated (FATTY ACIDS, UNSATURATED). (Grant & Hackh's Chemical Dictionary, 5th ed)
Fatty Acids, Omega-3
A group of fatty acids, often of marine origin, which have the first unsaturated bond in the third position from the omega carbon. These fatty acids are believed to reduce serum triglycerides, prevent insulin resistance, improve lipid profile, prolong bleeding times, reduce platelet counts, and decrease platelet adhesiveness.
Feminine Hygiene Products
Personal care items for women.
Dietary Supplements
Products in capsule, tablet or liquid form that provide dietary ingredients, and that are intended to be taken by mouth to increase the intake of nutrients. Dietary supplements can include macronutrients, such as proteins, carbohydrates, and fats; and/or MICRONUTRIENTS, such as VITAMINS; MINERALS; and PHYTOCHEMICALS.
RNA Caps
Nucleic acid structures found on the 5' end of eukaryotic cellular and viral messenger RNA and some heterogeneous nuclear RNAs. These structures, which are positively charged, protect the above specified RNAs at their termini against attack by phosphatases and other nucleases and promote mRNA function at the level of initiation of translation. Analogs of the RNA caps (RNA CAP ANALOGS), which lack the positive charge, inhibit the initiation of protein synthesis.
Vitamin D
A vitamin that includes both CHOLECALCIFEROLS and ERGOCALCIFEROLS, which have the common effect of preventing or curing RICKETS in animals. It can also be viewed as a hormone since it can be formed in SKIN by action of ULTRAVIOLET RAYS upon the precursors, 7-dehydrocholesterol and ERGOSTEROL, and acts on VITAMIN D RECEPTORS to regulate CALCIUM in opposition to PARATHYROID HORMONE.
Vitamin E
A generic descriptor for all TOCOPHEROLS and TOCOTRIENOLS that exhibit ALPHA-TOCOPHEROL activity. By virtue of the phenolic hydrogen on the 2H-1-benzopyran-6-ol nucleus, these compounds exhibit varying degree of antioxidant activity, depending on the site and number of methyl groups and the type of ISOPRENOIDS.
Heart Defects, Congenital
Developmental abnormalities involving structures of the heart. These defects are present at birth but may be discovered later in life.
Cardiac Care Facilities
Institutions specializing in the care of patients with heart disorders.
Eisenmenger Complex
A condition associated with VENTRICULAR SEPTAL DEFECT and other congenital heart defects that allow the mixing of pulmonary and systemic circulation, increase blood flow into the lung, and subsequent responses to low oxygen in blood. This complex is characterized by progressive PULMONARY HYPERTENSION; HYPERTROPHY of the RIGHT VENTRICLE; CYANOSIS; and ERYTHROCYTOSIS.
Transposition of Great Vessels
A congenital cardiovascular malformation in which the AORTA arises entirely from the RIGHT VENTRICLE, and the PULMONARY ARTERY arises from the LEFT VENTRICLE. Consequently, the pulmonary and the systemic circulations are parallel and not sequential, so that the venous return from the peripheral circulation is re-circulated by the right ventricle via aorta to the systemic circulation without being oxygenated in the lungs. This is a potentially lethal form of heart disease in newborns and infants.
Ductus Arteriosus, Patent
A congenital heart defect characterized by the persistent opening of fetal DUCTUS ARTERIOSUS that connects the PULMONARY ARTERY to the descending aorta (AORTA, DESCENDING) allowing unoxygenated blood to bypass the lung and flow to the PLACENTA. Normally, the ductus is closed shortly after birth.
Ductus Arteriosus
A fetal blood vessel connecting the pulmonary artery with the descending aorta.
Atlases as Topic
Collections of illustrative plates, charts, etc., usually with explanatory captions.
Aortic Valve Stenosis
A pathological constriction that can occur above (supravalvular stenosis), below (subvalvular stenosis), or at the AORTIC VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA.
Aortic Valve
The valve between the left ventricle and the ascending aorta which prevents backflow into the left ventricle.
Calcinosis
Pathologic deposition of calcium salts in tissues.
Urology
A surgical specialty concerned with the study, diagnosis, and treatment of diseases of the urinary tract in both sexes, and the genital tract in the male. Common urological problems include urinary obstruction, URINARY INCONTINENCE, infections, and UROGENITAL NEOPLASMS.
Cardiac Catheterization
Procedures in which placement of CARDIAC CATHETERS is performed for therapeutic or diagnostic procedures.
Heart Block
Impaired conduction of cardiac impulse that can occur anywhere along the conduction pathway, such as between the SINOATRIAL NODE and the right atrium (SA block) or between atria and ventricles (AV block). Heart blocks can be classified by the duration, frequency, or completeness of conduction block. Reversibility depends on the degree of structural or functional defects.

Pathological features of hypertrophic obstructive cardiomyopathy (HOCM) in the elderly. (1/45)

The pathological findings and available clinical data in 15 necropsy cases of HOCM, aged over 61 years, are reported. Three patients were in the eighth decade and 4 in the ninth; 8 were women. Five presented as sudden death, 2 died in congestive cardiac failure, and 7 died of unrelated conditions and HOCM was an apparently incidental postmortem finding. Compared with cases under 60 years, the hearts of the elderly patients were heavier and less likely to show typical asymmetrical hypertrophy, the free wall of the left ventricle also being thickened in two-thirds of the cases over 60 years. Most of the elderly cases showed a distinctive band of fibrous thickening over the upper part of the interventricular septum. This lesion had a "mirror image" relation to the lower part of the aortic surface of the anterior mitral cusp, with the histological features of a friction lesion. It appears to be a morphological expression of the systolic contact of anterior mitral cusp and interventricular septum seen on cineangiography and thus diagnostic of HOCM. Once formed, the fibrous band appears to persist even if the obstructive element disappears. It is, therefore, a valuable diagnostic feature indicating a diagnosis of HOCM in an age group where the morphology is usually not the classical asymmetrical form and in which this diagnosis is usually not considered.  (+info)

Subaortic stenosis diagnosed in the course of a twins pregnancy: a controversial management. (2/45)

Fixed subaortic stenosis, commonly associated with other congenital cardiac defects, is the cause of 10 per cent of cases of congenital obstruction of the left ventricular outflow. Corrective surgery is frequently a successful treatment, recommendations being based on the transaortic gradient in Europe while in the USA the most prevalent opinion is surgical repair independently of the gradient. We present a case of adult clinical onset of a fixed subaortic stenosis during pregnancy, in which hemodynamic changes are significant, that was medically treated and followed in the outpatient clinic of our hospital, and review the state of the art of the management and surgical indications of this condition.  (+info)

Ultrastructural features of degenerated cardiac muscle cells in patients with cardiac hypertrophy. (3/45)

Degenerated cardiac muscle cells were present in hypertrophied ventricular muscle obtained at operation from 12 (38%) of 32 patients with asymmetric septal hypertrophy (hypertrophic cardiomyopathy) or aortic valvular disease. Degenerated cells demonstrated a wide variety of ultrastructural alterations. Mildly altered cells were normal-sized or hypertrophied and showed focal changes, including preferential loss of thick (myosin) filaments, streaming and clumping of Z band material, and proliferation of the tubules of sarcoplasmic reticulum. Moderately and severely degenerated cells were normal-sized or atrophic and showed additional changes, including extensive myofibrillar lysis and loss of T tubules. The appearance of the most severely degenerated cells usually reflected the cytoplasmic organelle (sarcoplasmic reticulum, glycogen, or mitochondria) which underwent proliferation and filled the myofibril-free areas of these cells. Moderately and severely degenerated cells were present in areas of fibrosis, had thickened basement membranes, and had lost their intercellular connections. These observations suggest that degenerated cardiac muscle cells have poor contractile function and may be responsible for impaired cardiac performance in some patients with chronic ventricular hypertrophy.  (+info)

Neurally-mediated increase in calcineurin activity regulates cardiac contractile function in absence of hypertrophy. (4/45)

OBJECTIVE: The calcineurin pathway has been involved in the development of cardiac hypertrophy, yet it remains unknown whether calcineurin activity can be regulated in myocardium independently from hypertrophy and cardiac load. METHODS: To test that hypothesis, we measured calcineurin activity in a rat model of infrarenal aortic constriction (IR), which affects neurohormonal pathways without increasing cardiac afterload. RESULTS: In this model, there was no change in arterial pressure over the 4-week experimental period, and the left ventricle/body weight ratio did not increase. At 2 weeks after IR, calcineurin activity was increased 1.8-fold (P<0.05) and remained elevated at 4 weeks (1.7-fold, P<0.05). Similarly, the cardiac activity of calcium calmodulin kinase II (CaMKII) was increased significantly after IR, which confirms a regulation of Ca(2+)-dependent enzymes in this model. In cardiac myocytes, the increased activity of calcineurin was accompanied by a significant decrease in L-type Ca(2+) channel activity (I(Ca)) and contraction velocity (-dL/dt). Cardiac denervation prevented the activation of calcineurin after IR, which demonstrates that a neurohormonal mechanism is responsible for the changes in enzymatic activity. In addition, cardiac denervation suppressed the effects of IR on I(Ca) and -dL/dt, which shows that calcineurin activation is related to altered contractility. However, action potential duration, the densities of inward rectifier K(+) currents (I(K1)), and outward K(+) currents (I(to) and I(K)) were not altered in IR myocytes. CONCLUSIONS: Calcineurin can be activated in the heart through a neural stimulus, which induces alterations in Ca(2+) currents and contractility. These effects occur in the absence of myocyte hypertrophy, electrophysiological changes in action potential, and K(+) channel currents.  (+info)

Rheologic genesis of discrete subvalvular aortic stenosis: a Doppler echocardiographic study. (5/45)

To determine whether morphologic structures or abnormal flow patterns predispose to pathologic proliferation of subvalvular tissue, 26 patients (mean age 19.8 +/- 10.3 years) were studied greater than or equal to 6 months after operation for isolated discrete subvalvular aortic stenosis. The aortic root diameter and the mitral-aortic separation were measured with sector echocardiography. Flow patterns in the left ventricular outflow tract of these patients and control subjects were evaluated with a color flow mapping system optimized for the detection of turbulence. All control subjects had laminar flow throughout systole in the left ventricular outflow tract. By contrast, turbulence originating well below the site where the shelf had previously been resected was observed in 20 (77%) of the 26 patients. In 16 of these 20 patients turbulence was caused by a ridge, which in 13 patients could be identified as the offshoot of a ventricular band. In four patients the turbulence was caused by malalignment of the muscular and membranous septum, resulting in protrusion of the muscular septum into the outflow tract. Except for the latter four patients, the aortic root diameter was 84 +/- 10% of values predicted by body surface area, with values in six patients falling below the third percentile (p less than 0.01). The mitral-aortic separation was 9.7 +/- 3.5 mm, values in 21 patients falling above the 97th percentile (p less than 0.001). These data support the theory that discrete subvalvular aortic stenosis may be caused by a chronic flow disturbance, preferably in a small and long outflow tract. Left ventricular bands, if reaching the outflow tract, may be a factor.(ABSTRACT TRUNCATED AT 250 WORDS)  (+info)

Echocardiographic assessment of subvalvular aortic stenosis before and after operation. (6/45)

The development of two-dimensional and Doppler echocardiography has provided a noninvasive technique for the diagnosis and serial assessment of patients with subvalvular aortic stenosis. The clinical records and echocardiographic data were reviewed of all patients with subaortic stenosis diagnosed between 1983 and 1991. Of the 77 patients identified (45 male and 32 female), 28 had isolated subaortic stenosis and 49 had associated cardiac lesions. The most frequently encountered associated lesions were ventricular septal defect (n = 19) and coarctation of the aorta/interrupted aortic arch (n = 14). Serial echocardiographic studies, performed in 38 of the 77 patients, documented significant progression of the left ventricular outflow tract gradient in 25 patients (66%) and development of aortic regurgitation in 25 patients (66%). Surgical resection was performed in 36 patients. The preoperative outflow tract peak gradient was 62.9 +/- 31 mm Hg (range 0 to 153), whereas the immediate postoperative gradient was 14.4 +/- 14 mm Hg (range 0 to 67). The two patients with a significant residual gradient (37 and 67 mm Hg, respectively) in the immediate postoperative period had severe subaortic stenosis preoperatively with marked left ventricular hypertrophy and intracavitary gradient. The immediate postoperative echocardiograms demonstrated no worsening of aortic regurgitation in any patient and regression of regurgitation in one patient from mild to none. Intermediate-term follow-up studies were available for review in 13 postoperative patients at a mean of 4 years postoperatively. In 2(15%) of these 13 patients, subaortic stenosis recurred; however, the degree of aortic regurgitation did not increase in any patient.(ABSTRACT TRUNCATED AT 250 WORDS)  (+info)

Left subclavian artery to descending aorta bypass for coarctation physiology after descending aortic repair. (7/45)

Stenosis of the aorta observed after descending aorta replacement for traumatic aortic injury was managed by a placement of a bypass between the left subclavian artery and the distal descending aorta with success.  (+info)

Subaortic stenosis caused by an unusual fibrous blood-filled cyst of the left ventricle with outflow tract obstruction associated with a ventricular septal defect. (8/45)

A large blood-filled cyst formed from a fibrous tissue tag of a right ventricular septal aneurysm was successfully resected. This cyst, which was causing subaortic stenosis, was attached to the margin of the closed ventricular septal defect and not to the mitral valve itself nor the papillary muscle of the left ventricle.  (+info)

Fate of patients with fixed subaortic stenosis after surgical removal. | HeartFate of patients with fixed subaortic stenosis after surgical removal. | Heart
Thirty-nine consecutive patients, aged 5 to 57 years, were followed for two to 15 years with serial haemodynamic studies after removal of fixed subaortic stenosis, which was never a membrane. Two late deaths occurred, one sudden and one in congestive failure. Of 37 survivors, 25 were asymptomatic and could be classified as good or excellent if judged by well-being. Seven were symptomatic, two having had reoperation for fixed subaortic stenosis, and four needed long-term pacing. Evaluation, including the effect of isoprenaline, showed important dynamic obstruction in 17, five of whom redeveloped fixed obstruction. Seven had congestive features without outflow gradients, and 14 had neither congestion nor outflow obstruction. Complete assessment therefore confirmed that only 14 (36%) were haemodynamically satisfactory; two of them had permanent pacing, and four had had aortic valve surgery. Fixed subaortic stenosis should be removed early, when diagnosed, and completely before secondary ...

Recurrence of SAS during follow-up was defined as the new echocardiographic appearance of previously undetected lesions or Doppler gradients, or as significant progression of a residual lesion, causing a significant LVOT gradient (,20 mm Hg). Nonprogressive echogenic residual lesions were not included.. SAS recurred in 15 patients (20%), at a rate of 3.8 cases per 100 patient-years of follow-up (including re-recurrence). Multivariate hazard analysis demonstrated a strong independent influence of the preoperative gradient on recurrence per patient-year of follow up (p , 10−4). Inclusion of an age-gradient interaction variable did not influence outcome in this model, but lower patient age was also an independent predictor of recurrence (p = 0.002). A tunnel-type lesion was five times more likely than a discrete lesion to recur after transaortic resection: Five of seven patients with this type of obstruction (71.4%) had at least one recurrence versus only 10 (14.7%, p = 0.003) of 68 patients with ...

OBJECTIVE--To compare the incidence and prognosis of subaortic stenosis associated with a ventricular septal defect and to define the morphological basis of subaortic stenosis. DESIGN--Presentation and follow up data on 202 patients with subaortic stenosis seen at the Royal Liverpool Childrens Hospital between 1 January 1960 and 31 December 1991 were reviewed. Survivors were traced to assess their current clinical state. Necropsy specimens of 291 patients with lesions associated with subaortic stenosis were also examined. RESULTS--In the clinical study; 65 (32.1%) of the 202 patients with subaortic stenosis had a ventricular septal defect (excluding an atrioventricular septal defect). 32 of these patients had a short segment (fibromuscular) subaortic stenosis. 33 had subaortic stenosis produced by deviation of muscular components of the outflow tracts. In 17 patients (51.5%) this was caused by posterior deviation or extension of structures into the left ventricular outflow tract, resulting in ...

Aortic/Subaortic StenosisAortic/Subaortic Stenosis
PROGNOSIS: Mild subaortic stenosis is of no consequence to an individual dog and it is usually recommended that the dos not be bred. Moderate or severe subaortic stenosis may cause symptoms and may increase the risk of sudden death. Depending on the exact degree of severity, treatment may be required, and other measures (such as limiting activity) may be recommended to minimize the amount of work done by the heart. There is no cure for subaortic stenosis. Since it is thought to be of genetic origin it is often recommended that dogs with subaortic stenosis not be bred to avoid passing the disease along to future generations.. TREATMENT/PROCEDURE: If the disease is mild, treatment is not required. However, subaortic stenosis can get worse as a growing dog reaches its adult age and body size. Therefore, dogs with moderate or severe subaortic stenosis, may require medication. The most common form of treatment is a medication given orally called βeta blockers, which reduce the intensity of the ...

In this study, we have analyzed data on a large cohort of patients with relatively long postoperative follow-up of up to 20.7 years (median 8.2 years) to determine independent predictors of reoperation for recurrent discrete subaortic stenosis after successful primary resection. The present study used reoperation rather than recurrence as a concrete clinically relevant outcome. Earlier studies, which report recurrence rates ranging from 0% to 55%, are difficult to compare, because they use different criteria for recurrence of DSS or, often, report no specific criteria at all (7,9-12). Nonetheless, when looking at recurrence as a secondary outcome, we identified independent predictors similar to those identified for reoperation.. Although some previous studies have suggested that performing myomectomy during first surgery reduces the incidence of recurrence (9,17-19), other authors have questioned this finding (7,20). In the present study, patients who underwent myomectomy showed a trend toward ...

Subaortic Membrane and the Unsimplified Bernoulli Equation : Anesthesia & AnalgesiaSubaortic Membrane and the Unsimplified Bernoulli Equation : Anesthesia & Analgesia
Using this EOA, the indexed size for this patient is 0.6 cm2/m2, which is under the upper limit for acceptable size and consistent with that of PPM.5. This case also illustrates the discrete nature of these subaortic membranes and their ability to regrow6 (Fig. 2A); our patient had regrowth within 8 years. Subaortic membranes can present as membranous (approximately 5%) and tunnel-type (approximately 15%), further divided into short-segment and long-segment tunnels.6. Concern for PPM is an aspect of this case that makes the determination of the elevated gradients difficult to interpret. We were fortunate to have the TEE from her previous operation to assist in understanding the performance of this patients mechanical prosthesis. Based on the indexed valve area of 0.6 cm2/m2, the size is below a valve size of 0.65 cm2/m2, consistent with that of severe PPM.5 The historical peak gradient does not discount PPM as a cause of elevated gradients, but it confirms that the valve function has not ...

Risk factors for reoperation after relief of congenital subaortic stenosis - Zurich Open Repository and ArchiveRisk factors for reoperation after relief of congenital subaortic stenosis - Zurich Open Repository and Archive
BACKGROUND: Congenital subaortic stenosis entails a lesion spectrum, ranging from an isolated obstructive membrane, to complex tunnel narrowing of the left outflow associated with other cardiac defects. We review our experience with this anomaly, and analyze risk factors leading to restenosis requiring reoperation. METHODS: From 1994 to 2006, 58 children (median age 4.3 years, range 7 days-13.7 years) underwent primary relief of subaortic stenosis. Patients were divided into simple lesions (n=43) or complex stenosis (n=15) associated with other major cardiac defects. Age, pre- and postoperative gradient over the left outflow, associated aortic or mitral valve insufficiency, chromosomal anomalies, arteria lusoria, and operative technique (membrane resection (22) vs associated myectomy (34) vs Konno (2)) were analyzed as risk factors for reoperation (Kaplan-Meier, Cox regression). RESULTS: There was no operative mortality. Median follow-up spanned 2.7 years (range 0.1-10), with one late death at 4 ...

Dr. Bansal responded: Nice question!. Excellent - physiology at work! in subaortic stenosis, it is basically the muscular component of left ventricular outflow tract which is narrow. With increased preload - greater blood in lv - this stretches the muscle and allows for easier exit through the lvot and softer sound of murmur.

If the narrowing is severe, open heart surgery may be necessary to remove the excess tissue. This can be a challenging operation. It is usually possible to significantly improve the narrowing, but it is not usually possible to remove it completely. Valves, including the aortic valve, can be damaged during the surgery. The tissue that is removed at surgery can grow back over time, so it is important that patients with subaortic stenosis continue to to be monitored regularly in outpatients. All heart operations carry some risk of death or major complications such as permanent brain damage, kidney damage or pneumonia. For subaortic stenosis the risk of dying at operation is small (about 1 in 100) and the risk of brain damage is also small (around 1 in 100). There is also a small risk (around 1 in 50) of the hearts electrical system being damaged; if this happens the heart rate will be much slower than normal and a further procedure will be required to implant a pacemaker to make the heart beat ...

Methods: Retrospective review of medical records of dogs diagnosed with severe, uncomplicated SAS (pressure gradient [PG] ≥80mmHg) between 1999 and 2011. Results: Fifty dogs met the inclusion criteria. Twenty-seven dogs were treated with a beta blocker and 23 received no treatment. Median age at diagnosis was significantly greater in the untreated group (1.2 versus ...

Angiographic Anatomy of the Left Ventricle and Mitral Valve in Idiopathic Hypertrophic Subaortic Stenosis | CirculationAngiographic Anatomy of the Left Ventricle and Mitral Valve in Idiopathic Hypertrophic Subaortic Stenosis | Circulation
The angiographic features of the left ventricle were examined in patients with idiopathic hypertrophic subaortic stenosis who had clinical and hemodynamic evidence of obstruction. Of 36 combined hemodynamic and angiographic studies considered to be technically satisfactory, 33 showed a characteristic combination of abnormalities. In the frontal projection in systole, a linear radiolucent area extended across the left ventricular outflow tract 2 to 2.5 cm below the aortic annulus, at a level corresponding to the site of intraventricular pressure change. In the left oblique and lateral projections, the mitral leaflets did not swing posteriorly in a normal fashion, but projected into the outflow tract during mid and late systole. The radiolucent line, seen in the frontal views, was considered to represent contact of the leading edge of the leaflet with the hypertrophied muscular interventricular septum. The jet of mitral regurgitation, when present, was seen immediately below the anterior mitral ...

On the Question of Obstruction in Idiopathic Hypertrophic Subaortic Stenosis | Annals of Internal Medicine | American College...On the Question of Obstruction in Idiopathic Hypertrophic Subaortic Stenosis | Annals of Internal Medicine | American College...
Only 10 years have elapsed since the concept of functional obstruction to left ventricular ejection was introduced to clinical medicine (1), and in the interim the features of obstructive cardiomyopathy, or idiopathic hypertrophic subaortic stenosis, have become generally recognized. It seems certain that the increasingly frequent recognition of this disease has resulted largely from wider application of left heart catheterization techniques; nevertheless, while the diagnosis initially was based on hemodynamic features peculiar to this disease, it has become possible with increasing experience to recognize and assess the severity of this lesion on clinical grounds alone (2).. Work originating in a ...

PY - 2003/11. Y1 - 2003/11. N2 - Background. Aortic stenosis (AS) is encountered in approximately 5% of children with heart disease. The indications for surgery and the surgical techniques for AS are well established. This report focuses on the early and long-term outcomes in children with AS over a 40-year period. Methods. Included in this study were 508 patients ranging in ages from 1 day to 19 years, who were operated on for AS between 1960 and 2002 . Eighty-one percent (414 of 508) of the patients had left ventricular outflow tract obstruction (LVOTO) at a single level: 40 supravalvar, 242 valvar (critical AS in 85 neonates and young infants and in 157 older children), and 132 subvalvar. Nineteen percent (94 of 508) of the patients had LVOTO at more than one level. Associated congenital cardiac defects ...

A lot has been going on since the last update. It has been extremely tough, because lost two puppies, Cabot and Jack. Cabot passed away at 5 weeks without any warning signs in my arms and was sent to EVIRA to be autopsied. While waiting for the results we rushed everyone else to the sauna cottage for a few very nervous days, writing up every time the pups ate, peed and pooped. We had no idea of what could have taken Cabot away from us. After a phone call from EVIRA, it didnt take our concerns away, but we were able to breathe and move the puppies back into their cottage and out door area. Cabot had passed away from SAS (subaortic stenosis). It IS quite a common disease in Newfoundlands, but something we had never encountered before. After calling up several cardiologists, we were able to book a doppler ultrasound appointment for the rest of the puppies a week away (age 6 weeks) at Animagi Jyv skyl , a three hour drive away.. Having to drive Annina & Dave (who had been looking after the puppies ...

To the Editor:. We read with great interest the article by Maron et al1 reporting hypertrophic cardiomyopathy (HCM) as a predominantly obstructive disease. The authors describe in their carefully conducted study a cohort of 320 patients, 70% of whom present with either resting or provocable obstruction of the left ventricular outflow tract.. Our own data from a cohort of 186 unrelated HCM patients confirm that distribution: 65% of our patients presented with significant left ventricular outflow tract gradient either at rest or on exercise.2 We assume that the patients examined by Maron et al were also familially unrelated. However, HCM is an autosomal dominant heritable disorder with a 50% chance of transmission to the offspring. To make a reliable estimation for the prevalence of obstruction in HCM, it would be reasonable to also include other affected family members into this estimation. The wide spectrum of clinical expression is a well-known phenomenon of HCM and is sometimes particularly ...

Idiopathic hypertrophic subaortic stenosis (IHSS). also called hypertrophic obstructive cardiomyopathy (HOCM), is a genetic form of hypertrophic cardiomyopathy (HCM) Characterized by marked hypertrophy of the interventricular septum:. Reduces the diameter of the left ventricular outflow tract, leading to outflow tract obstruction. Overtime it leads to:. LVH and increased diastolic filling pressure. It is the most common (Mendelian) genetic heart disease, occurring at rate of approximately 1 in 500. Autosomal dominant pattern of inheritance with variable penetrance leading to a high degree of phenotypic heterogeneity, which makes genetic testing implausible Monogenic disease where in 1 of the 13 genes lead to a single amino acid change in proteins that compose the sarcomere complex Presents after puberty (Average in mid-20s, but increasingly seen in 40-50s).

What is Aortic Stenosis in PugsWhat is Aortic Stenosis in Pugs
The aorta is the largest artery in the body. It is the main blood vessel that serves as a passageway for oxygen-filled blood to pass from the left side of the heart to be distributed throughout the entire body. Aortic stenosis may be due to the malformation of the aorta or a defect in the left ventricle.

Case report: A 28-year-old male presented with grade III to IV dyspnea with previous history of infective endocarditis. Preoperative transthoracic echocardiogram (TTE) showed calcified BAV with severe aortic valve regurgitation and stenosis, severe tricuspid regurgitation, and pulmonary artery hypertension along with ruptured SOVA arising from right coronary sinus and draining into the right ventricle. Intraoperative TEE confirmed the TTE findings and in addition showed the presence of two jets arising from the SOVA draining into right ventricle, a subaortic membrane, and a perforation in the aortic cusp opening into left ventricle. The ruptured SOVA was repaired using single patch technique and aortic valve was replaced. The completeness of the repair was checked using TEE to exclude failure of closure of additional opening if any and the patient was discharged from hospital after 7 days of uneventful postoperative course ...

A to Z: Aortic StenosisA to Z: Aortic Stenosis
The aorta, the bodys largest blood vessel, starts from the left ventricle of the heart and carries oxygen-rich blood to the body. Blood flows from the left ventricle into the aorta through the aortic valve, one of the four valves in the heart.. In aortic stenosis, the aortic valve is narrow. This decreases the amount of blood flowing into the aorta and out to the rest of the body. Aortic stenosis is most common in adults over 50, but can be present at birth (congenital).. Aortic stenosis makes the heart work harder to pump blood to the body. Over time, this added stress can weaken the heart and lead to life-threatening heart problems.. Aortic stenosis can be identified before birth, allowing babies born with severe cases to be treated right away. Babies with aortic stenosis can have trouble gaining weight, problems with feeding, and serious breathing problems that develop soon after birth. Older children also may have a heart murmur. These children may be sent for an echocardiogram, a type of ...

So it is with interest that I noticed a new experimental technology introduced to our group yesterday which is about to begin clinical trials at our institution. This device uses a minimally invasive, percutaneous pericardial approach that applies a device that squeezes together the left ventricular walls beneath the mitral leaflets and maintains this force by way of a subvalvular cord passed through the heart walls and held on place by two epicardial pads on the outside surface of the heart. It is hoped that this technology would improve mitral valve closure while limiting the progressive dilation of the left ventricle ...
