Right Ventricular Dysfunction and Pulmonary Vascular Elastance Coupling in Candidates for Advanced Heart Failure Therapies

Purpose Acute and chronic right ventricular (RV) dysfunction are common complications experienced by patients with advanced heart failure, particularly after receiving mechanical circulatory support. An elevated right atrial pressure to pulmonary artery wedge pressure ratio (RAP:PAWP) or a reduced pulmonary artery (PA) pulsatility index (PAPI) may identify patients at risk of RV dysfunction. We examined the relationship of these markers to RV...
