Echocardiographic Ramp test for continuous-flow left ventricular assist devices: do loading conditions matter?

Abstract

OBJECTIVES This study investigated whether continuous AI and/or elevated mean arterial pressure (MAP) were associated with false positive results for flow obstruction in echocardiographic ramp speed tests in patients with a continuous-flow left ventricular assist device. BACKGROUND Failure to reduce the left ventricular end-diastolic diameter (LVEDD) with… (More)
