Abstract

Functional assessment of continuous-flow left ventricular assist devices (LVADs) is usually performed with the patient at rest. This study compared echocardiographic indices of contraction and filling pressure with invasive measures in 12 ambulatory LVAD patients undergoing symptom-limited bicycle exercise. Exercise induced an increase in cardiac output, systolic pulmonary artery pressure, and diastolic pulmonary artery pressure. Although no changes in left ventricular dimensions or fractional shortening were seen on echocardiography, systolic mitral annular motion (S') increased significantly (in parallel with cardiac output) and diastolic E/e' ratio decreased (correlating inversely with diastolic pulmonary artery pressure). These findings emphasize the potential role of exercise echocardiography in studying exercise hemodynamics in LVAD patients.
