Big endothelin-1 as a clinical marker for ventricular tachyarrhythmias in patients with post-infarction left ventricular aneurysm.

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.

Assessment of myocardial viability by cardiac MRI.

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.

Differences in Biomarkers Pattern Between Severe Isolated Right and Left Ventricular Dysfunction After Cardiac Surgery.

The role of natriuretic peptides in the management, outcomes and prognosis of sepsis and septic shock.

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...

Imaging Strategies for Evaluating Low-Flow, Low-Gradient Aortic Stenosis with Reduced and Preserved Left Ventricular Ejection Fraction.

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.

Fractional Flow Reserve Guided PCI in Patients With and Without Left Ventricular Hypertrophy: a DANAMI-3-PRIMULTI Sub-study.

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.

Right Ventricular Abnormalities on Cardiovascular Magnetic Resonance Imaging in Patients With Sarcoidosis.

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.

Assessment of right ventricular function in advanced heart failure with nonischemic dilated cardiomyopathy: insights of right ventricular elastance.

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 dysfunction in neurologically deceased organ donors: An observational study in a tertiary-care organ donor referral centre.

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."

Usefulness of strain imaging echocardiography in arrhythmogenic right ventricular cardiomyopathy: clinical perspective.

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 ...

Asymptomatic Degenerative Mitral Regurgitation: A Review.

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.

Extracorporeal Membrane Oxygenation for Takotsubo Cardiomyopathy That Developed after Mitral Valve Replacement.

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...

Risk Stratification of Acute Pulmonary Embolism Based on the Clot Volume and Right Ventricular Dysfunction on CT Pulmonary Angiography.

To test the feasibility of clot volume and right ventricular dysfunction for risk stratification of acute pulmonary embolism (APE) patients.

Assessment and Acute Management of Decompensated Heart Valves in the Intensive Care Unit - a Current Review.

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...

Calcifications of left ventricular outflow tract in patients with severe aortic stenosis: Another topic of discussion for the heart team!

Reoperative mitral valve surgery via sternotomy or right thoracotomy: A propensity-matched analysis.

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.

Not all mitral stenosis are due to valve disease.

Analysis of left ventricular diastolic energy loss in patients with aortic stenosis with preserved ejection fraction by using vector flow mapping.

Feature tracking for assessment of diastolic function by cardiovascular magnetic resonance imaging.

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...

Baseline Right Ventricular Dysfunction Predicts Worse Outcomes in Patients Undergoing Cardiac Resynchronization Therapy (CRT) Implantation.

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.

Combined Tricuspid and Mitral Versus Isolated Mitral Valve Repair for Severe Mitral and Tricuspid Regurgitation: An Analysis From the TriValve and TRAMI Registries.

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.

Transapical mitral valve-in-ring procedure with a novel self-expandable transcatheter heart valve: first- and last-in-man report.

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.

Effect of Baseline Left Ventricular Ejection Fraction on 2-Year Outcomes After Transcatheter Aortic Valve Replacement: Analysis of the PARTNER 2 Trials.

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.

Degenerative Mitral Valve Repair Restores Life Expectancy.

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.
