Right ventricular global work efficiency: A reliable non-invasive estimate of right ventricular contractility.

ABSTRACT:

Background

Right ventricular (RV) myocardial work (RVMW) recently emerged as a non-invasive alternative for the assessment of RV contractility. However, none of the prior studies assessed its variations under different haemodynamic conditions. We aimed to evaluate the variations of the components of RVMW in heart failure (HF) patients with pulmonary hypertension (PH) undergoing a reversibility test.

Methods

Consecutive HF patients with reduced ejection fraction who underwent right heart catheterization and echocardiography at our institution were prospectively enrolled. Patients with PH and augmented pulmonary vascular resistance who achieved normalization of pulmonary pressures after the reversibility test using vasodilators underwent a second echocardiographic assessment u
