Ventricular tachyarrhythmia is the leading cause of death in post-infarction patients. Big endothelin-1 (ET-1) is a potent vasoconstrictor peptide and plays a role in ventricular tachyarrhythmia development. The aim of this study was to investigate the association between the serum concentration of big ET-1 and ventricular tachyarrhythmia in post-infarction left ventricular aneurysm (PI-LVA) patients.
Left ventricular systolic dysfunction because of coronary artery disease is common, and ascertaining which patients will benefit from revascularization can be challenging. Viability testing is an accepted means by which to base this decision, with multiple noninvasive imaging modalities available for this purpose. This review aims to highlight the key role of cardiac magnetic resonance in myocardial viability assessment, with a focus on its unique strengths over other imaging modalities.
To find out if there are any differences in biomarkers between severe isolated right ventricular (RV) dysfunction and severe isolated left ventricular (LV) dysfunction after cardiac surgery using cardiopulmonary bypass.
Sepsis continues to be a leading public health burden in the United States and worldwide. With the increasing use of advanced laboratory technology, there is a renewed interest in the use of biomarkers in sepsis to aid in more precise and targeted decision-making. Natriuretic peptides have been increasingly recognized to play a role outside of heart failure. They are commonly elevated among critically ill patients in the setting of cardiopulmonary dysfunction and may play a role in identifying patients with...
Aortic stenosis (AS) is one of the most common valvular heart diseases, and aortic valve replacement (AVR) provides both symptomatic and survival benefit in symptomatic severe AS patients. The purpose of this review is to discuss low-flow low-gradient AS which is still a challenging diagnostic entity.
To investigate the correlation between fractional flow reserve (FFR) and diameter stenosis in patients with STEMI with and without left ventricular hypertrophy (LVH), and the influence of LVH on complete FFR-guided revascularization versus culprit only, in terms of risk of clinical outcome.
This study aimed to determine the prevalence on cardiac magnetic resonance (CMR) of right ventricular (RV) systolic dysfunction and RV late gadolinium enhancement (LGE), their determinants, and their influences on long-term adverse outcomes in patients with sarcoidosis.
The right ventriculoarterial coupling (R-V/A), a measure of right ventricular systolic dysfunction (RVSD) adaptation/maladaptation to chronic overload, and consequent pulmonary hypertension, has been little investigated in nonischemic dilated cardiomyopathy (NIDCM). We examined the correlates of R-V/A and traditional echocardiographic indices of RVSD, over the spectrum of pulmonary hypertension and tertiles of mean pulmonary artery pressures (PAPm).
Right ventricular RV dysfunction among transplant recipients correlates with transplant outcome, but its frequency in donors is unknown. The purpose of this study was to describe the epidemiology of RV dysfunction in potential heart donors."
Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a rare, but severe disease that predisposes patients to ventricular arrhythmias, heart failure, and increased risk of sudden cardiac death. Because of the broad spectrum of phenotypic expressions, diagnostic assessment is often challenging. Speckle-tracking echocardiography has emerged as an alternative technique enhancing the performance of standard echocardiography in ARVC patients, leading to an early detection of subtle ventricular abnormalities ...
Most patients with severe degenerative mitral regurgitation (DMR) are likely to require surgery, but years can pass until there is a clear indication for it. The timing of mitral valve surgery for asymptomatic patients with severe DMR is controversial, and current guidelines are limited because they are based on nonrandomized studies and expert opinion.
Takotsubo cardiomyopathy is a transient systolic and diastolic left ventricular dysfunction that presents several wall-motion abnormalities, while the coronary artery shows normal findings. Because patients with Takotsubo cardiomyopathy present with symptoms similar to acute coronary syndrome, the initial diagnosis and treatment are often difficult. The condition is often precipitated by acute emotional or physical stress and frequently occurs in postmenopausal women. Takotsubo cardiomyopathy may also occur...
To test the feasibility of clot volume and right ventricular dysfunction for risk stratification of acute pulmonary embolism (APE) patients.
The acute valvular dysfunction is a rapidly growing and critical condition in the intensive care unit with a cardiogenic shock as the most serious clinical entity. There are clearly defined guidelines for the diagnosis and treatment of heart failure and for stable patients with valvular heart disease. However, data regarding acutely valvular decompensated patients are currently limited. In case of secondary organ dysfunction despite optimal medical treatment, various percutaneous interventional procedures s...
There is, as yet, no broad consensus regarding the optimal surgical approach for patients requiring reoperative mitral valve surgery. Consequently, we sought to evaluate the perioperative outcomes for patients undergoing redo mitral surgery via right mini thoracotomy as compared with traditional resternotomy.
To assess the agreement of cardiovascular magnetic resonance imaging (CMRI) feature-tracking (FT) parameters with echocardiography to diagnose diastolic dysfunction; to determine whether a similar parameter to mitral inflow early diastolic velocity to early diastolic tissue velocity ratio (E/e') can increase accuracy of imaging by dividing the phase contrast (PC) mitral inflow E-wave (E) with a CMRI-FT parameter; to compare the agreement between CMRI-FT and PC diastolic function assessment using echocardiog...
Cardiac resynchronization therapy (CRT) has been shown to improve survival in patients with systolic heart failure, wide QRS duration, and left-bundle-branch-block (LBBB). However, CRT outcomes stratified by right ventricular (RV) function at implant have not been well studied.
The aim of this study was to retrospectively compare the characteristics, procedural courses, and outcomes of patients presenting with concomitant mitral regurgitation (MR) and tricuspid regurgitation (TR) in the TriValve (Transcatheter Tricuspid Valve Therapies) and TRAMI (Transcatheter Mitral Valve Interventions) registries.
Interventional therapy of failing surgical mitral valve replacement and repair is an appealing option in patients who are not eligible for redo surgery. We herein report on the first-in-human use of a repositionable, self-expandable transcatheter heart valve with motorized delivery for a transapical mitral valve-in-ring procedure. After implantation, fluoroscopy showed no residual regurgitation and pressure measurements did not reveal any signs of left ventricular outflow tract obstruction.
Impaired left ventricular function is associated with worse prognosis among patients with aortic stenosis treated medically or with surgical aortic valve replacement. It is unclear whether reduced left ventricular ejection fraction (LVEF) is an independent predictor of adverse outcomes after transcatheter aortic valve replacement.
Mitral valve repair (MVr) for severe, degenerative mitral regurgitation (MR) is the gold standard, as medical management carries poor prognosis. However, despite clear benefit of MVr, many eligible patients are untreated. This study investigated whether MVr restores patients to normal life expectancy, at any age of operation, by comparing long-term survival of post-MVr patients to the life expectancy of the general United States (U.S.) population.
