Myocardial Work by Speckle-Tracking Echocardiography in Heart Transplant Recipients: Association Between Global Work Efficiency and Coronary Allograft Vasculopathy.

Coronary allograft vasculopathy (CAV) is a leading cause of morbidity and mortality after heart transplantation. CAV is often diagnosed in later stages or during routine screening in asymptomatic subjects. Myocardial work (MW), calculated using left ventricular global longitudinal strain (LV-GLS) and systemic blood pressure, may be associated with the presence of CAV and outperform conventional echocardiographic parameters.

Prediction of right ventricular failure after left ventricular assist device implantation: role of vasodilator challenge.

Aims: Pulmonary artery pulsatility index (PAPi) is an indicator of right ventricular (RV) function and an independent predictor of right ventricular failure (RVF) following left ventricular assist device (LVAD) implantation. Administration of vasodilator challenge during right heart catheterization (RHC) could reduce RV workload allowing a better assessment of its functional reserve.

Methods And Results: Patients undergoing LVAD implantation at our Institution between May 2013 and August 2021 were enrolled.

Heartmate II axial-flow left ventricular assist system: management, clinical review and personal experience.

Objectives: The excellent results with left ventricular assist devices (LVADs) have revolutionized the treatment options for end-stage heart failure. The use of pulsatile devices is associated with significant comorbidity and limited durability. The axial-flow HeartMate II LVAD represents the new generation of devices.

Fulminant myocarditis during HIV seroconversion: recovery with temporary left ventricular mechanical assistance.

A 32-year-old male was admitted to our intensive care unit for low cardiac output syndrome. Echocardiography was suggestive of extensive hypokinesia and the ejection fraction was 0.22.
