Advantage of Pulsatility in Left Ventricular Reverse Remodeling and Aortic Insufficiency Prevention During Left Ventricular Assist Device Treatment.
BACKGROUND A continuous flow (CF) left ventricular assist device (LVAD) has various advantages over a pulsatile flow (PF) LVAD, but the extent of preventing aortic insufficiency (AI) by each type of LVAD remains controversial. METHODSANDRESULTS Of 86 patients with non-ischemic cardiomyopathy who underwent LVAD implantation between 2006 and 2015, 20 propensity score-matched patients with PF LV...
متن کاملAortic Insufficiency with Left Ventricular Dysfunction
Seventeen patients, ages 14-74 years, with severe, isolated aortic insufficiency and reduced ejection fraction (0.25-0.49) underwent aortic valve replacement between January 1973 and July 1977. Three had coronary artery disease and also underwent coronary bypass surgery. By New York Heart Association criteria, one patient was functional class IV, seven were class III, seven were class II and tw...
متن کاملNovel Left Ventricular Assist System
We propose a Novel Left Ventricular Assist System (Novel LVAS) as a bridge to cardiac transplantation and to functional heart recovery in advanced heart failure. This report regards the principles that led to its development. It is our hope that the design of a high-peak-output pump of smaller size will lead to improved functional capacity, when compared with currently available left ventricula...
متن کاملPrevalence, significance, and management of aortic insufficiency in continuous flow left ventricular assist device recipients.
BACKGROUND Aortic insufficiency (AI) is increasingly recognized as a complication of continuous flow left ventricular assist device support; however, its long-term prevalence, clinical significance, and efficacy of potential interventions are not well known. METHODS AND RESULTS We studied the prevalence and management of AI in 232 patients with continuous flow left ventricular assist device a...
متن کاملThe development of aortic insufficiency in left ventricular assist device-supported patients.
BACKGROUND Aortic insufficiency (AI) following left ventricular assist device (LVAD) placement can affect device performance. The aim of this study was to examine AI development following LVAD implantation. METHODS AND RESULTS Echocardiograms (n=315) from 78 subjects undergoing HeartMate-XVE (n=25 [32%]) or HeartMate-II (n=53 [68%]) implantations from 2004 to 2008 were reviewed. Studies were ...
