A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.

Extracorporeal Membrane Oxygenation
Process that is gone through in order for a device to receive approval by a government regulatory agency. This includes any required preclinical or clinical testing, review, submission, and evaluation of the applications and test results, and post-marketing surveillance. It is not restricted to FDA.
A group of diseases in which the dominant feature is the involvement of the CARDIAC MUSCLE itself. Cardiomyopathies are classified according to their predominant pathophysiological features (DILATED CARDIOMYOPATHY; HYPERTROPHIC CARDIOMYOPATHY; RESTRICTIVE CARDIOMYOPATHY) or their etiological/pathological factors (CARDIOMYOPATHY, ALCOHOLIC; ENDOCARDIAL FIBROELASTOSIS).
Ventricular Dysfunction, Right
A condition in which the RIGHT VENTRICLE of the heart was functionally impaired. This condition usually leads to HEART FAILURE or MYOCARDIAL INFARCTION, and other cardiovascular complications. Diagnosis is made by measuring the diminished ejection fraction and a depressed level of motility of the right ventricular wall.
Heart Defects, Congenital
Intra-Aortic Balloon Pumping
Counterpulsation in which a pumping unit synchronized with the patient's electrocardiogram rapidly fills a balloon in the aorta with helium or carbon dioxide in early diastole and evacuates the balloon at the onset of systole. As the balloon inflates, it raises aortic diastolic pressure, and as it deflates, it lowers aortic systolic pressure. The result is a decrease in left ventricular work and increased myocardial and peripheral perfusion.
Ventricular Dysfunction, Left
A condition in which the LEFT VENTRICLE of the heart was functionally impaired. This condition usually leads to HEART FAILURE; MYOCARDIAL INFARCTION; and other cardiovascular complications. Diagnosis is made by measuring the diminished ejection fraction and a depressed level of motility of the left ventricular wall.
Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
Compassionate Use Trials
Providing an investigational therapy to a patient who is not eligible to receive that therapy in a clinical trial, but who has a serious or life-threatening illness for which other treatments are not available. Compassionate use trials allow patients to receive promising but not yet fully studied or approved therapies when no other treatment option exists. Also called expanded access trial.
Devices in which blood and oxygen are separated by a semipermeable membrane, generally of Teflon or polypropylene, across which gas exchange occurs. The membrane may be arranged as a series of parallel plates or as a number of hollow fibers; in the latter arrangement, the blood may flow inside the fibers, which are surrounded by gas, or the blood may flow outside the fibers and the gas inside the fibers. (Dorland, 28th ed)
Cardiac Output, Low
A state of subnormal or depressed cardiac output at rest or during stress. It is a characteristic of CARDIOVASCULAR DISEASES, including congenital, valvular, rheumatic, hypertensive, coronary, and cardiomyopathic. The serious form of low cardiac output is characterized by marked reduction in STROKE VOLUME, and systemic vasoconstriction resulting in cold, pale, and sometimes cyanotic extremities.
Devices intended to replace non-functioning organs. They may be temporary or permanent. Since they are intended always to function as the natural organs they are replacing, they should be differentiated from PROSTHESES AND IMPLANTS and specific types of prostheses which, though also replacements for body parts, are frequently cosmetic (EYE, ARTIFICIAL) as well as functional (ARTIFICIAL LIMBS).
Ventricular Function, Right
A disorder of cardiac function caused by insufficient blood flow to the muscle tissue of the heart. The decreased blood flow may be due to narrowing of the coronary arteries (CORONARY ARTERY DISEASE), to obstruction by a thrombus (CORONARY THROMBOSIS), or less commonly, to diffuse narrowing of arterioles and other small vessels within the heart. Severe interruption of the blood supply to the myocardial tissue may result in necrosis of cardiac muscle (MYOCARDIAL INFARCTION).
Prostheses and Implants
Artificial substitutes for body parts, and materials inserted into tissue for functional, cosmetic, or therapeutic purposes. Prostheses can be functional, as in the case of artificial arms and legs, or cosmetic, as in the case of an artificial eye. Implants, all surgically inserted or grafted into the body, tend to be used therapeutically. IMPLANTS, EXPERIMENTAL is available for those used experimentally.
Equipment and Supplies
Recovery of Function
A technique for assisting the circulation by decreasing the afterload of the left ventricle and augmenting the diastolic pressure. It may be achieved by intra-aortic balloon, or by implanting a special pumping device in the chest, or externally by applying a negative pressure to the lower extremities during cardiac systole.

A class of statistical procedures for estimating the survival function (function of time, starting with a population 100% well at a given time and providing the percentage of the population still well at later times). The survival analysis is then used for making inferences about the effects of treatments, prognostic factors, exposures, and other covariates on the function.
Durable Medical Equipment
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.
Inflammatory processes of the muscular walls of the heart (MYOCARDIUM) which result in injury to the cardiac muscle cells (MYOCYTES, CARDIAC). Manifestations range from subclinical to sudden death (DEATH, SUDDEN). Myocarditis in association with cardiac dysfunction is classified as inflammatory CARDIOMYOPATHY usually caused by INFECTION, autoimmune diseases, or responses to toxic substances. Myocarditis is also a common cause of DILATED CARDIOMYOPATHY and other cardiomyopathies.
The pressure within a CARDIAC VENTRICLE. Ventricular pressure waveforms can be measured in the beating heart by catheterization or estimated using imaging techniques (e.g., DOPPLER ECHOCARDIOGRAPHY). The information is useful in evaluating the function of the MYOCARDIUM; CARDIAC VALVES; and PERICARDIUM, particularly with simultaneous measurement of other (e.g., aortic or atrial) pressures.
Septal Occluder Device
Foramen Ovale, Patent
A nonparametric method of compiling LIFE TABLES or survival tables. It combines calculated probabilities of survival and estimates to allow for observations occurring beyond a measurement threshold, which are assumed to occur randomly. Time intervals are defined as ending each time an event occurs and are therefore unequal. (From Last, A Dictionary of Epidemiology, 1995)

Predictive Value of Tests
In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.

Reproducibility of Results
The statistical reproducibility of measurements (often in a clinical context), including the testing of instrumentation or techniques to obtain reproducible results. The concept includes reproducibility of physiological measurements, which may be used to develop rules to assess probability or prognosis, or response to a stimulus; reproducibility of occurrence of a condition; and reproducibility of experimental results.
Placement of a balloon-tipped catheter into the pulmonary artery through the antecubital, subclavian, and sometimes the femoral vein. It is used to measure pulmonary artery pressure and pulmonary artery wedge pressure which reflects left atrial pressure and left ventricular end-diastolic pressure. The catheter is threaded into the right atrium, the balloon is inflated and the catheter follows the blood flow through the tricuspid valve into the right ventricle and out into the pulmonary artery.
Studies in which subsets of a defined population are identified. These groups may or may not be exposed to factors hypothesized to influence the probability of the occurrence of a particular disease or other outcome. Cohorts are defined populations which, as a whole, are followed in an attempt to determine distinguishing subgroup characteristics.
Central Venous Pressure
An abnormally rapid ventricular rhythm usually in excess of 150 beats per minute. It is generated within the ventricle below the BUNDLE OF HIS, either as autonomic impulse formation or reentrant impulse conduction. Depending on the etiology, onset of ventricular tachycardia can be paroxysmal (sudden) or nonparoxysmal, its wide QRS complexes can be uniform or polymorphic, and the ventricular beating may be independent of the atrial beating (AV dissociation).
Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care.

Intrauterine Devices, Copper
A potentially lethal cardiac arrhythmia that is characterized by uncoordinated extremely rapid firing of electrical impulses (400-600/min) in HEART VENTRICLES. Such asynchronous ventricular quivering or fibrillation prevents any effective cardiac output and results in unconsciousness (SYNCOPE). It is one of the major electrocardiographic patterns seen with CARDIAC ARREST.

Age as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or the effect of a circumstance. It is used with human or animal concepts but should be differentiated from AGING, a physiological process, and TIME FACTORS which refers only to the passage of time.
Heart Septal Defects, Atrial
Developmental abnormalities in any portion of the ATRIAL SEPTUM resulting in abnormal communications between the two upper chambers of the heart. Classification of atrial septal defects is based on location of the communication and types of incomplete fusion of atrial septa with the ENDOCARDIAL CUSHIONS in the fetal heart. They include ostium primum, ostium secundum, sinus venosus, and coronary sinus defects.

Rheumatic Heart Disease
A class of statistical methods applicable to a large set of probability distributions used to test for correlation, location, independence, etc. In most nonparametric statistical tests, the original scores or observations are replaced by another variable containing less information. An important class of nonparametric tests employs the ordinal properties of the data. Another class of tests uses information about whether an observation is above or below some fixed value such as the median, and a third class is based on the frequency of the occurrence of runs in the data.

Copulsation balloon for right ventricular assistance: preliminary trials. (1/805)BACKGROUND: Options for management of acute right ventricular (RV) failure are limited. This report describes preliminary testing of a temporary RV assist device that acts by direct compression of the RV. The system comprises a pancake-shaped silicone balloon (5 cm diameter) connected to a drive console that delivers a 65-mL pneumatic pulse during cardiac systole. METHODS AND RESULTS: Initial in vivo tests were performed on 6 pigs (weight, 41+/-4 kg). RV wall motion and stroke volume were monitored via transesophageal echocardiography. Acute RV failure was created by graded right coronary ligation, which yielded a 63% reduction in RV stroke volume (39.9+/-8.2 to 14.7+/-1.9 mL; P<0.002). We secured the balloon over the RV free wall by attaching it to the edges of the opened pericardium. The sternum was then reapproximated, and data were collected with the device off and on (every beat). Device placement had no deleterious effect on RV function. Balloon activation returned RV stroke volumes to normal (37.8+/-9.2 mL) and increased mean pulmonary artery pressures from 13+/-2 to 16+/-3 mm Hg (P<0.01). RV compression did not induce or exacerbate tricuspid regurgitation. Mean aortic pressure improved from postinfarction levels but did not return to normal. CONCLUSIONS: We conclude that the pulmonary circulation can be supported in the short term via cardiac compression and that balloon copulsation techniques for short-term RV failure should be tested in long-term models.

Improved survival rates support left ventricular assist device implantation early after myocardial infarction. (2/805)OBJECTIVES: Implantation of left ventricular assist devices (LVADs) early after acute myocardial infarction (MI) has traditionally been thought to be associated with high mortality rates due to technical limitations and severe end-organ dysfunction. At some experienced centers, doctors have refrained from earlier operation after MI to allow for a period of hemodynamic and end-organ stabilization. METHODS: We retrospectively investigated the effect of preoperative MI on the survival rates of 25 patients who received a Thermocardiosystems Incorporated LVAD either <2 weeks (Early) (n = 15) or >2 weeks (Late) (n = 10) after MI. Outcome variables included perioperative right ventricular assistance (and right-sided circulatory failure), hemodynamic indexes, percent transplanted or explanted, and mortality. RESULTS: No statistically significant differences were demonstrated between demographic, perioperative or hemodynamic variables between the Early and Late groups. Patients in the Early group demonstrated a lower rate of perioperative mechanical right ventricular assistance, but had a higher rate of perioperative inhaled nitric oxide use. In addition, 67% of patients in the Early group survived to transplantation and 7% to explantation, findings comparable to those in the Late group (60% and 0% respectively). CONCLUSIONS: This clinical experience suggests that patients may have comparable outcomes whether implanted early or late after acute MI. These data therefore support the early identification and timely application of this modality in post-MI LVAD candidates, as this strategy may also reveal a subgroup of patients for whom post-MI temporary LVAD insertion may allow for full ventricular recovery.

Children may survive severe myocarditis with prolonged use of biventricular assist devices. (3/805)The outcome of acute myocarditis with cardiogenic shock is poor. In some children in whom aggressive medical treatment fails, artificial replacement of heart function may offer lifesaving support until the myocardium has recovered. Four previously healthy children (three boys aged 4, 6, and 1 years; one girl aged 5) developed acute myocarditis with ventricular failure and multiorgan dysfunction caused by low cardiac output. Biventricular assist devices (BVAD) were implanted for prolonged support. In three children cardiac function improved and after up to 21 days mechanical support could be withdrawn. They had full recovery of heart function. In the fourth patient there was no myocardial recovery after a period of 20 days. He underwent orthotopic heart transplantation with an uneventful postoperative course. Prolonged circulatory support with BVAD is an effective method for bridging until cardiac recovery or transplantation in children. (+info)
Decreased expression of tumor necrosis factor-alpha in failing human myocardium after mechanical circulatory support : A potential mechanism for cardiac recovery. (4/805)BACKGROUND: An increasing number of observations in patients with end-stage heart failure suggest that chronic ventricular unloading by mechanical circulatory support may lead to recovery of cardiac function. Tumor necrosis factor-alpha (TNF-alpha) is a proinflammatory cytokine capable of producing pulmonary edema, dilated cardiomyopathy, and death. TNF-alpha is produced in the myocardium in response to volume overload; however, the effects of normalizing ventricular loading conditions on myocardial TNF-alpha expression are not known. We hypothesize that chronic ventricular unloading by the placement of a left ventricular assist device (LVAD) may eliminate the stress responsible for persistent TNF-alpha expression in human failing myocardium. METHODS AND RESULTS: Myocardial tissue was obtained from normal hearts and from paired samples of 8 patients with nonischemic end-stage cardiomyopathy at the time of LVAD implantation and removal. Tissue sections were stained for TNF-alpha, and quantitative analysis of the stained area was performed. We found that TNF-alpha content decreased significantly after LVAD support. Furthermore, the magnitude of the changes did not correlate with the length of LVAD support, although greater reductions in myocardial TNF-alpha content were found in patients who were successfully weaned off the LVAD who did not require transplantation. CONCLUSIONS: These data show for the first time that chronic mechanical circulatory assistance decreases TNF-alpha content in failing myocardium; furthermore, we suggest that the magnitude of the change may predict which patients will recover cardiac function.

Surgical management of the patient with an implanted cardiac device: implications of electromagnetic interference. (5/805)OBJECTIVE: To identify the sources of electromagnetic interference (EMI) that may alter the performance of implanted cardiac devices and develop strategies to minimize their effects on patient hemodynamic status. SUMMARY BACKGROUND DATA: Since the development of the sensing demand pacemaker, EMI in the clinical setting has concerned physicians treating patients with such devices. Implanted cardiovertor defibrillators (ICDs) and ventricular assist devices (VADs) can also be affected by EMI. METHODS: All known sources of interference to pacemakers, ICDs, and VADs were evaluated and preventative strategies were devised. RESULTS: All devices should be thoroughly evaluated before and after surgery to make sure that its function has not been permanently damaged or changed. If electrocautery is to be used, pacemakers should be placed in a triggered or asynchronous mode; ICDs should have arrhythmia detection suspended before surgery. If defibrillation is to be used, the current flow between the paddles should be kept as far away from and perpendicular to the lead system as possible. Both pacemakers and ICDs should be properly shielded if magnetic resonance imaging, positron emission tomography, or radiation therapy is to be used. The effect of EMI on VADs depends on the model. Magnetic resonance imaging adversely affects all VADs except the Abiomed VAD, and therefore its use should be avoided in this population of patients. CONCLUSIONS: The patient with an implanted cardiac device can safely undergo surgery as long as certain precautions are taken. (+info)
Extracorporeal life support to left ventricular assist device bridge to heart transplant: A strategy to optimize survival and resource utilization. (6/805)BACKGROUND: The use of extracorporeal life support (extracorporeal membrane oxygenation [ECMO]) as a direct bridge to heart transplant in adult patients is associated with poor survival. Similarly, the use of an implantable left ventricular assist device (LVAD) to salvage patients with cardiac arrest, severe hemodynamic instability, and multiorgan failure results in poor outcome. The use of LVAD implant in patients who present with cardiogenic shock who have not been evaluated for transplantation or who have sustained a recent myocardial infarction also raises concerns. ECMO may provide reasonable short-term support to patients with severe hemodynamic instability, permit recovery of multiorgan injury, and allow time to complete a transplant evaluation before long-term circulatory support with an implantable LVAD is instituted. After acquisition of the HeartMate LVAD (Thermo Cardiosystems, Inc), we began using ECMO as a bridge to an implantable LVAD and, subsequently, to transplantation in selected high-risk patients. METHODS AND RESULTS: From October 1, 1996, through September 30, 1998, 32 adult patients who presented with refractory cardiogenic shock (cardiac index <2.0 L. min(-1). m(-2), with systolic blood pressure <100 mm Hg and pulmonary capillary wedge pressure >/=24 mm Hg and dependent on >/=2 inotropes with or without intra-aortic balloon pump) were evaluated and accepted as candidates for mechanical assistance as a bridge to transplant. Of the 32 patients, 14 (group I) had a cardiac arrest or severe hemodynamic instability (systolic blood pressure 3 mg/dL or oliguria; international normalized ratio >1.5 or transaminases >5 times normal or total bilirubin >3 mg/dL; and needing mechanical ventilation). Group I patients were placed on ECMO support; 7 underwent subsequent LVAD implant and 1 was bridged directly to transplant. Six patients in group I survived to transplant hospitalization discharge. The remaining 18 patients (group II) underwent LVAD implant without ECMO support; 12 survived to transplant hospitalization discharge and 2 remained alive with ongoing LVAD support and awaited transplant. One-year actuarial survival from the initiation of circulatory support was 43% in group I and 75% in group II. One-year actuarial survival from the time of LVAD implant in group I, conditional on surviving ECMO, was 71% (P=NS compared with group II). CONCLUSIONS: In appropriately selected high-risk patients, the rate of LVAD survival after initial ECMO support was not significantly different from the survival rate after LVAD support alone. An initial period of resuscitation with ECMO is an effective strategy to salvage patients with extreme hemodynamic instability and multiorgan injury. Use of LVAD resources is improved by avoiding LVAD implant in a very-high-risk cohort of patients who do not survive ECMO. (+info)
Quantitative changes in T-cell populations after left ventricular assist device implantation: relationship to T-cell apoptosis and soluble CD95. (7/805)BACKGROUND: Left ventricular assist devices (LVADs) are currently being evaluated as permanent therapy for end-stage heart failure. Because life-threatening infections limit successful long-term device implantation, we investigated the relationship between quantitative T-cell defects in LVAD recipients and CD95-mediated T-cell apoptosis. METHODS AND RESULTS: Immunological studies were performed in NYHA class IV patients awaiting cardiac transplantation who received either a TCI Heartmate left ventricular assist device (LVAD) or medical management. Fluorochrome-labeled Mabs were used in T-cell phenotypic analyses. T-cell apoptosis was measured by annexin V binding of T cells cultured in medium for 24 hours. Circulating serum levels of soluble CD95 were measured by ELISA. LVAD recipients had a relative lymphopenia and reduction in CD4 T-cell levels compared with NYHA class IV heart failure controls. These observations were confirmed in a longitudinal study in LVAD recipients, which showed that device implantation was accompanied by progressive and sustained reductions in circulating CD4 T-cell levels. These abnormalities in LVAD recipients were accompanied by increased levels of circulating soluble CD95 and by excessive CD4 and CD8 T-cell apoptosis. Susceptibility to induction of apoptosis was >2-fold greater for CD4 T cells than for CD8 T cells. CONCLUSIONS: These results suggest that the reduction in CD4 T-cell levels accompanying LVAD implantation is a consequence of an augmented pathway of CD95-mediated apoptosis. The clinical consequences of these abnormalities may include increased prevalence of systemic infections. (+info)
Myocardial gene expression of regulators of myocyte apoptosis and myocyte calcium homeostasis during hemodynamic unloading by ventricular assist devices in patients with end-stage heart failure. (8/805)BACKGROUND: In patients with end-stage heart failure, characterized by an increased susceptibility to cardiomyocyte apoptosis and a labile cardiomyocyte calcium homeostasis, a ventricular assist device (VAD) is implanted for bridging to cardiac transplantation and results in myocardial unloading. Although phenotype changes in the failing heart are assumed to result from hemodynamic overload, the reversibility of these changes under unloading is unknown. METHODS AND RESULTS: By use of quantitative reverse-transcription polymerase chain reaction, mRNA expression analyses were performed on left ventricular specimens obtained from 10 nonfailing donor hearts (from 8 patients with dilated cardiomyopathy and 2 patients with coronary heart disease) at the time of VAD implantation and 36 to 169 days later during VAD removal with subsequent cardiac transplantation. In terminally failing hearts before VAD support, left ventricular mRNA analyses revealed increased Pro-ANP, reduced antiapoptotic Bcl-x(L) and antiapoptotic Fas isoform FasExo6Del, and a decreased ratio of sarcoplasmic reticulum Ca(2+)-ATPase per sarcolemmal Na(+)-Ca(2+) exchanger in comparison with nonfailing ventricles. After VAD unloading, ventricular transcription of Pro-ANP was immediately normalized, and apoptotic DNA fragmentation was attenuated. In patients with dilated cardiomyopathy, mRNAs of Bcl-x(L) and FasExo6Del/Fas were enhanced depending on time on VAD. The Bcl-x(L) mRNA level correlated positively with that of the Bcl-x(L) protein. Transcription of sarcoplasmic reticulum Ca(2+)-ATPase/Na(+)-Ca(2+) exchanger demonstrated recovery in only 4 of 10 patients. CONCLUSIONS: Mechanical support of the failing heart induces a time-dependent change in myocardial gene expression compatible with a decreased susceptibility to apoptosis. (+info)

Twenty-three patients (16%) developed late RHF during waiting period. Of ...
Continuous-flow left ventricular assist device outflow graft stenting: by Chelsey T. Wood, MFA, Elizabeth J. Maynes, MD et al.
Introduction: Stenosis in the continuous-flow left ventricular assist device (CF-LVAD) outflow graft can be caused by various mechanical and anatomical factors. Increasingly, percutaneous management has been utilized to re-establish adequate CF-LVAD flow. We sought to evaluate indications for such interventions and their outcomes. Methods: An electronic search was performed to identify all studies in the English literature reporting CF-LVAD outflow graft stenting for various etiologies. Twenty-one studies consisting of 26 patients were included in the analysis. Results: Median patient age was 59 years [45.8-67.0] and 65.4% (17/26) were male. 58.3% (14/24) of patients had HeartWare HVAD, 37.5% (9/24) had HeartMate II LVAD, and 4.2% (1/24) had HeartMate III LVAS. Median time from device placement to outflow graft stenting was 24.0 months [7.8-30.4]. 76.9% of patients (20/26) presented with heart failure. 34.6% (9/26) had outflow graft thrombosis, 34.6% (9/26) stenosis, 11.5% (3/26) kinking, 11.5% (3/26)

BACKGROUND New generation continuous-flow left ventricular assist devices (LVADs) utilise centrifugal pumps. Data concerning their effect on patient haemodynamics, ventricular function and tissue perfusion is limited. We aimed to document these parameters following HeartWare centrifugal continuous-flow LVAD (HVAD) implantation and to assess the impact of post-operative right heart failure (RHF). METHODS We reviewed 53 consecutive patients (mean age 49.5 ± 14.1 yrs) with HVAD implanted in the left ventricle, at St. Vincents Hospital, Sydney, between January 2007 and August 2012. Available paired right heart catheterisation (n=35) and echocardiography (n=39) data was reviewed to assess response of invasive haemodynamics and ventricular function to LVAD support. RESULTS A total of 28 patients (53%) were implanted from interim mechanical circulatory support.

Management of patients with end-stage heart disease treated with an implantable left ventricular assist device in a...
This thesis describes the management of patients treated with mechanical circulatory support devices for short- or long-term use. Twenty-four patients suffering from postcardiotomy heart failure were treated with a minimally invasive axial flow pump. The device was effective in unloading the failing left ventricle and in maintaining an adequate systemic circulation. The principles of perioperative monitoring, and pharmacological therapy are outlined. The pump was also used as an alternative to the heart-lung machine in conjunction with coronary artery bypass surgery. Together with a short-acting β-blocker, esmolol, the heart was decompressed and heart motion was reduced, facilitating bypass surgery on the beating heart. The anesthesiological considerations using this method are described.. An implantable left ventricular assist device was used as a bridge to heart transplantation in 10 patients. We were interested in assessing the possibility to establish such a treatment program at a ...

Background: In this study, we aimed to investigate frequency, patterns, etiologies, and costs of unplanned readmissions after left ventricular assist device implantation.. Methods: Between April 2012 and September 2016, 99 unplanned readmissions of a total of 50 consecutive bridge-to-transplant patients (45 males, 5 females; mean age 46.9±10.3 years; range, 19 to 67 years) who were successfully discharged after left ventricular assist device implantation were retrospectively analyzed. Patient demographic data, hemodynamic measurements before implantation, and readmissions after discharge were recorded. Hospitalizations due to major problems which were unable to be managed in routine outpatient clinic were accepted as unplanned readmissions. Survival analysis was performed.. Results: The readmission rate was 1.7 per year after discharge. Survival of patients who were readmitted within the first 90 days was found to be significantly lower than those without early readmission. The most common ...

TY - JOUR. T1 - Current Axial-Flow Devices-the HeartMate II and Jarvik 2000 Left Ventricular Assist Devices. AU - John, Ranjit. PY - 2008/9/1. Y1 - 2008/9/1. N2 - The increased applicability and excellent results with left ventricular assist devices (LVADs) have revolutionized the treatment options available for patients with end-stage heart failure. Until recently, most patients who have undergone LVAD implantation have been supported by pulsatile devices. Unfortunately, the use of the latter devices is associated with significant comorbidity, primarily as a result of their large size and limited durability. The HeartMate II and the Jarvik 2000 pumps, both of which incorporate axial-flow and rotary pump technology represent the next generation of devices. The clinical use of these newer axial-flow pumps have resulted in superior outcomes, including significantly reduced complication rates with improved durability. However, as with all new technology, axial-flow LVADs have also introduced a ...

Differential gene expression and genomic patient stratification following left ventricular assist device support | JACC:...
Although heart transplantation is an effective interventional therapy for end-stage heart failure (HF), donor hearts are consistently in limited supply. Hence, patients who experience clinical deterioration before transplant availability are frequently given mechanical circulatory support in the form of a left ventricular assist device (LVAD), employed as a bridge to transplant. To date, the utility, efficacy, and safety of LVAD support as a bridge to transplant has been widely recognized (1,2). Importantly, LVAD support, similar to all drugs that exert beneficial effects on mortality in patients with HF, also favorably impacts the left ventricular (LV) remodeling process (3-6). Recent evidence has demonstrated that unloading the LV in patients with end-stage HF by LVAD support can lead toward reverse remodeling of myocardial structure and function (6-15). Studies of LVAD-mediated reverse remodeling have described changes such as decreased myocyte size (8,12,14), increased myocyte ...
Preoperative predictors of survival in patients with Thoratec ventricular assist devices as a bridge to heart transplantation....
Approximately two-thirds of patients implanted with ventricular assist devices recover sufficiently to requalify for heart transplantation, and the other one-third die of complications that are often secondary to delayed ventricular assist device implantation and subsequent end-organ failure. To determine whether any preoperative predictors of survival exist, univariate statistics and multivariate stepwise logistic regression analysis were performed on pre-ventricular assist device demographics, hemodynamics, and blood chemistry in 186 patients receiving Thoratec ventricular assist devices (Thoratec Laboratories Corp., Berkeley, Calif.) while awaiting transplantation. The duration of circulatory support averaged 19.6 days (maximum, 226 days). One hundred thirty-seven patients (74%) received biventricular support, 47 received isolated left ventricular assist devices, and two received right ventricular assist devices. The average blood flow was 5.0 +/- 0.9 L/min. One hundred eighteen patients (63%)

Background: A continuous flow left ventricular assist device (c-LVAD) provides a better clinical outcome for patients with severe heart failure than pulsatile flow LVAD (p-LAVD). However, the frequency of cerebrovascular events, crucial complications, is largely unknown, especially in patients with systemic infection. We examined the prevalence of stroke related to systemic infection in patients with these 2 LVAD types.. Methods: We reviewed 114 consecutive patients (c-LVAD group: n=47, 66.6 patient-years; p-LVAD group: n=67 patients, 63.5 patient-years) who received LVAD support at Osaka University Hospital from 2005-2012. Cerebrovascular complications were defined as a neurological deficit concomitant with a coinciding lesion shown by computed tomography. Anticoagulation was given according to the manufacturers recommendation. Stroke frequency was compared between the groups.. Results: During LVAD support, 8 patients (c-LVAD, 1; p-LVAD, 7) died from stroke. As for cerebral infarctions, 10 ...
Statement Regarding the Pre and Post Market Assessment of Durable, Implantable Ventricular Assist Devices in the United States:...
The incorporation of complex medical device technologies into clinical practice is governed by critical oversight of the US Food and Drug Administration. This regulatory process requires a judicious balance between assuring safety and efficacy, while providing efficient review to facilitate access to innovative therapies. Recent contrasting views of the regulatory process have emphasized the difficulties in obtaining an optimal balance. Mechanical circulatory support has evolved to become an important therapy for patients with advanced heart failure with the advent of more durable, implantable ventricular assist devices. The regulatory oversight of these new technologies has been difficult owing to the complexities of these devices, associated adverse event profile, and severity of illness of the intended patient population. Maintaining a regulatory environment to foster efficient introduction of safe and effective technologies is critical to the success of ventricular assist device therapy and ...

Echocardiographic Identification of Elevated Filling Pressures in LVAD Patients | JACC: Journal of the American College of...
Mechanical circulatory support systems, such as continuous-flow left ventricular assist devices (CF-LVADs), are being increasingly used as destination therapy or bridge to heart transplantation in patients with end-stage heart failure. The rate of implantation has nearly doubled since 2010, with ,5,000 devices placed in the last 2 years in the United States alone (2). Despite survival improvement with these devices, the clinical course of the patient is punctuated by a number of adverse events, including residual heart failure, which frequently warrants additional investigations.. Inadequate left ventricular (LV) unloading, often as a consequence of suboptimal left ventricular assist device (LVAD) parameters or comorbidities, is central to the worsening symptoms; some of these events can be treated with simple but effective options (e.g., optimize the device settings, use diuretics). However, other causes, such as right ventricular (RV) failure, can present with heart failure-like symptoms ...

Ventricular assist device therapy and heart transplantation: Benefits, drawbacks, and outlook
End-stage heart failure is associated with significant morbidity and mortality. Heart transplantation has the potential to offer a return to daily activities for critically ill patients and is the gold standard therapy. However, heart transplantations are decreasing yearly with a historic low in Germany in 2017. By striking contrast, both waiting list numbers and waiting time have increased owing to a lack of acceptable donor organs. Ventricular assist devices (VAD) represent a reasonable therapeutic alternative for patients on heart transplantation waiting lists. Patients ineligible for transplantation may undergo VAD implantation as a destination therapy. However, the necessity for life-long anticoagulation must be weighed against bleeding complications in potential VAD candidates. VAD-dependent patients also face risks of driveline infections, in addition to restricted activities of daily living owing to limited battery capacities. Given Germanys low transplantation rate, VAD implantation ...

Video: Left Ventricular Assist Device - Merck Manuals Consumer Version
The heart is a beating muscle that pumps blood to the lungs and body through the circulatory system. Inside the heart are four chambers that are responsible for collecting blood and then redistributing it to the body. The top two chambers are called the right and left atria, and the larger chambers on the bottom are called the right and left ventricles. The left ventricle is responsible for pumping 3 to 6 liters of blood to the entire body every minute. However, disease can sometimes cause failure of the left ventricle to pump enough blood to keep the body functioning normally. In this case, a machine called a left ventricular assist device, or LVAD, can help the heart perform its work. A left ventricular assist device is a mechanical pump-type apparatus that is surgically implanted in the body. It helps maintain the pumping ability of a heart that cannot effectively work on its own. Many of the new LVADs are implanted directly into the left ventricle and propel blood through a tube that is ...
Design of a right ventricular mock circulation loop as a test bench for right ventricular assist devices : Biomedical...
AbstractRight heart failure (RHF), e.g. due to pulmonary hypertension (PH), is a serious health issue with growing occurrence and high mortality rate. Limited efficacy of medication in advanced stages of the disease constitutes the need for mechanical circulatory support of the right ventricle (RV). An essential contribution to the process of developing right ventricular assist devices (RVADs) is the in vitro test bench, which simulates the hemodynamic behavior of the native circulatory system. To model healthy and diseased arterial-pulmonary hemodynamics in adults (mild and severe PH and RHF), a right heart mock circulation loop (MCL) was developed. Incorporating an anatomically shaped silicone RV and a silicone atrium, it not only enables investigations of hemodynamic values but also suction events or the handling of minimal invasive RVADs in an anatomical test environment. Ventricular pressure-volume loops of all simulated conditions as well as pressure and volume waveforms were recorded and compared

AmSECT : Blogs : Bleeding and thrombosis associated with ventricular assist device therapy
Click on the title to purchase the article.. Summary:. Over the past decade, continuous-flow rotary pumps have dramatically improved survival for patients with advanced systolic heart failure. Bleeding and thrombosis, however, continue to be the Achilles heel of left ventricular assist device (LVAD) therapy. There is a dynamic and complex interaction between the patient and pump. The net effect of a variety of hematologic derangements, such as hemolysis, high-molecular-weight von Willebrand degradation, platelet activation and diminished pulsatility, is poorly understood. A combination of these factors mediates the common adverse events of gastrointestinal bleeding, device thrombosis and stroke. In this review we incorporate information from translational investigations in LVAD patients to understand how continuous-flow pumps activate the coagulation system and platelets predisposing to thrombosis, while, in parallel, degrade high-molecular-weight von Willebrand factor and trigger abnormal ...

Over the last several decades, doctors and researchers have developed a new generation of devices to mechanically assist blood circulation. Some of these devices replace the function of the left ventricle, which is weakened in heart failure patients. Others supplement it rather than replace it. Assist devices are therefore markedly different from their total artificial heart predecessors.. The Jarvik 2000® Ventricular Assist Device is sometimes called a booster pump. Implanted inside the intact biological heart, it aids the left ventricle in ejecting blood. The flow produced by the Jarvik 2000 is synchronized with the heartbeat so that the blood moves in natural pulses. Most heart failure patients retain enough heart function to make this kind of support more reliable and effective - not to mention more comfortable - than that of a total artificial heart or device that produces the total output of a ...
Genomic blood test predicts survival rates after surgery for advanced heart failure - David Geffen School of Medicine - Los...
Mechanical circulatory support devices, such as ventricular assist devices and temporary total artificial hearts, can be surgically implanted in people with advanced heart failure to help the hearts pumping function.. But people with advanced heart failure often also suffer from multi-organ dysfunction syndrome, which can lead to death after a device is implanted and is associated with atypical white blood cell activity. When patients and doctors are considering a mechanical assist device, current clinical methods used to predict treatment results have limitations: They do not perform well in very sick patients and they do not use molecular information. That lack of precision in predicting treatment outcomes can complicate the shared decision-making process between patients and their doctors.. Dr. Mario Deng, the studys principal investigator, was also a co-developer of an FDA-approved molecular blood test called AlloMap, which is used to diagnose organ rejection in heart transplant ...

All patients had excellent resolution of the ischemia and salvage of the extremity. Half of the procedures were done at the bedside with the remainder performed in the operating room. No long-term infections or ischemic sequelae resulted from the procedures in the nine patients available for long-term follow-up. The use of femorofemoral bypass grafting is, therefore, recommended in patients with severe ...
Optimization of Transcutaneous Energy Transmission Systems Suitable for Left Ventricular Assist Devices | Journal of Medical...
Transcutaneous energy transmission systems (TETS) wirelessly transmit power through the skin. TETS is particularly desirable for ventricular assist devices (VAD), which currently require cables through the skin to power the implanted pump. Current implantable TETS systems are not optimized for high power VAD applications. Optimizing the inductive link of the TET system is a multi-parameter problem. Most current techniques to optimize the design simplify the problem by combining parameters leading to sub-optimal solutions. In this paper we present an optimization method using a genetic algorithm to handle a larger set of parameters, which leads to a more optimal design.. ...

New Trends in High Risk Ventricular Tachycardia Catheter Ablation | Journal of Cardiovascular Disease Research
Abstract:. Ventricular tachycardia (VT) is one of the major causes of sudden cardiac death (SCD). In general, VT could be managed with antiarrhythmic drugs (AADs) therapy, catheter ablation and implantable cardioverter defibrillators (ICD). While the AADs therapy and catheter ablation have been shown to reduce the recurrence of VT, only the ICD therapy is effective in aborting SCD. The recently published VANISH trial reveals that VT catheter ablation significantly decreases the rate of death, VT storm and appropriate ICD shock comparing with an escalation of AADs therapy for ischemic cardiomyopathy (ICM). However, the mapping strategies and feasibility of VT catheter ablation are often limited by the hemodynamically intolerant VT. Substrate modification strategy and percutaneous left ventricular assist device (pLVAD) are often used to overcome the hemodynamic intolerance. So far there are no large-scale randomized clinical trials comparing different mapping strategies in the setting of ...
Artificial heart - Wikipedia
Patients who have some remaining heart function but who can no longer live normally may be candidates for ventricular assist devices (VAD), which do not replace the human heart but complement it by taking up much of the function. The first Left Ventricular Assist Device (LVAD) system was created by Domingo Liotta at Baylor College of Medicine in Houston in 1962.. Another VAD, the Kantrowitz CardioVad, designed by Adrian Kantrowitz boosts the native heart by taking up over 50% of its function. Additionally, the VAD can help patients on the wait list for a heart transplant. In a young person, this device could delay the need for a transplant by 10-15 years, or even allow the heart to recover, in which case the VAD can be removed. The artificial heart is powered by a battery that needs to be changed several times while still working. The first heart assist device was approved by the FDA in 1994, and two more received approval in 1998. While the original assist devices emulated the ...

Impact of Preoperative Atrial Fibrillation on Postoperative Thromboemb by Linnea Xuereb, Pauline H. Go et al.
BACKGROUND: The incidence of atrial fibrillation (AF) among patients undergoing left ventricular assist device (LVAD) implantation is high. However, the impact of AF on clinical outcomes has not been clarified. We reviewed our 9-year experience of continuous flow (CF) LVADs to determine the impact of preoperative AF on stroke, device thrombosis, and survival. METHODS: Between March 2006 and May 2015, 231 patients underwent implantation of 240 CF LVADs, 127 (52.9%) as bridge to transplantation and 113 (47.1%) as destination therapy. Effect of AF on postoperative outcomes was assessed by using Kaplan-Meier survival and Cox proportional hazard regression. RESULTS: There were 78 patients (32.5%) with preoperative AF with a mean age of 55.7 ± 11.4 years. A similar incidence of stroke was found in patients with and without AF, 12.8% versus 16.0%, respectively (p = 0.803). Survival was similar, with 1-, 6-, 12-, and 24-month survivals of 96.2%, 91.7%, 84.5%, and 69.2%, respectively, for AF patients, versus 93

In the 1970s, technologies for mechanical circulatory support emerged as an alternative to prolong the life of patients who need to replace the native organ. Until now, there are not enough organs available to be transplanted, so the main purpose of these devices is to provide survival to patients. According to American researchers however, mechanical circulatory support was developed as a therapy for end-stage heart failure when heart transplantation was not yet a useful treatment modality (because the introduction of cyclosporine, which has enabled the increasing success of heart transplantation, has occurred only in the 1980s). That means that the mechanical circulatory support was preceding to heart transplantation. In fact, since the first heart-lung machine used in open-heart surgeries, the use of artificial devices changed the death concept (now considered as brain death), which made possible to replace human hearts. More than change the life and death concept, howev. er, the wider ...

ECMO for Adult Heart Disease: The Importance of a Team Approach - American College of Cardiology
Introduction. The use of veno-veno extracorporeal membrane oxygenation (ECMO)* for profound respiratory failure has been shown to improve survival when compared to conventional ventilator management strategies.1 Despite significant increases in utilization, survival for these complex, if not catastrophic, problems has only improved slightly over the years. Similarly, when used to provide both pulmonary and cardiac support, veno-arterial ECMO can be a useful and potentially life-saving therapeutic modality.2 Unfortunately, given the circumstances, randomized trials and standard practices are difficult to obtain. Nevertheless, there is an increasing amount of literature demonstrating the value of extracorporeal support in the setting of high-risk percutaneous coronary intervention (PCI), particularly when associated with acute cardiogenic shock.3. Background. Conceptually, ECMO is quite simple. Venous drainage is obtained either through the large peripheral veins (femoral, internal jugular, ...

Low Frequency Of Canonical Human Leukocyte Antigen Alloimmunization In Heart Transplantation Candidates With Ventricular Assist...
Purpose: Screening for anti-HLA antibodies in heart transplantation candidates is complicated by transfusions as well as by the presence of ventricular assist devices (VADs), which have been shown to be an independent risk factor for developing anti-human leukocyte antigen (HLA) antibodies. As a result, these patients require frequent antibody screens to monitor for the development of anti-HLA antibodies following these sensitizing events. The goal of this study is to define the frequency of HLA alloimmunization in patients that have received VADs.. *Methods: We performed a retrospective analysis of heart transplantation candidates at our center who received a VAD from 1/2015-10/2018, had at least one negative antibody screen pre-VAD (median of 13 days pre-VAD), and were screened at least once post-VAD (first screen performed at a median of 26 days post-VAD). Patients were screened an average of four times post-VAD, and screens after transplantation were not included.. *Results: Of the 52 ...
Frontiers | The TIDE-Algorithm for the Weaning of Patients With Cardiogenic Shock and Temporarily Mechanical Left Ventricular...
Objectives: Mechanical circulatory support (MCS) is often required to stabilize therapy-refractory cardiogenic shock patients. Left ventricular (LV) unloading by mechanical ventricular support (MVS) via percutaneous devices, such as with Impella® axial pumps, alone or in combination with extracorporeal life support (ECLS, ECMELLA approach), has emerged as a potential clinical breakthrough in the field. While the weaning from MCS is essentially based on the evaluation of circulatory stability of patients, weaning from MVS holds a higher complexity, being dependent on bi-ventricular function and its adaption to load. As a result of this, weaning from MVS is mostly performed in the absence of established algorithms. MVS via Impella is applied in several cardiogenic shock etiologies, such as acute myocardial infarction (support over days) or acute fulminant myocarditis (prolonged support over weeks, PROPELLA). The time point of weaning from Impella in these cohorts of patients remains unclear. We here
