OBJECTIVES This study sought to develop a novel approach to optimizing continuous-flow left ventricular assist device (CF-LVAD) function and diagnosing device malfunctions. BACKGROUND In CF-LVAD patients, the dynamic interaction of device speed, left and right ventricular decompression, and valve function can be assessed during an echocardiography-monitored speed ramp test. METHODS We devised a unique ramp test protocol to be routinely used at the time of discharge for speed optimization… CONTINUE READING
