Management of aortic valve insufficiency in patients supported by long-term continuous flow left ventricular assist devices.

چکیده
Continuous flow (CF) left ventricular assist devices (LVADs) have yielded improved outcomes in patient survival and quality of life compared with first-generation pulsatile pumps; however, they have been associated with an increased incidence of postimplant aortic valve insufficiency (AI), which can have can have serious clinical consequences if not diagnosed and treated expeditiously. We reviewed our experience with AI after LVAD since the start of our CF LVAD program. From March 2006 through July 2011, 94 patients with chronic heart failure underwent implantation of a HeartMate II (HM II) LVAD. Severe AI developed in three patients after CF LVAD implantation. The clinical records of these patients were reviewed to analyze the presenting signs and symptoms of AI, identify the duration of LVAD support when the AI occurred, how the AI was treated, and the outcomes.

Background/Introduction Better understanding of hemodynamic alterations caused by long-term use of continuous-flow left ventricular assist devices (LVAD) is necessary to evaluate their impact onto the native heart and major vessels. In particular, aortic insufficiency is a known complication after LVAD implantation and may be related to alteration of pressure distribution on the leaflets of the...

OBJECTIVES This study sought to assess the effectiveness of a novel percutaneous method to treat left ventricular assist device (LVAD)-associated severe aortic insufficiency (AI) in a series of patients determined to be poor reoperative candidates. BACKGROUND The increased use of continuous-flow LVAD in advanced heart failure has led to marked changes in the management of patients with this c...
متن کاملWhy pulsatility still matters: a review of current knowledge
Continuous-flow left ventricular assist devices (LVAD) have become standard therapy option for patients with advanced heart failure. They offer several advantages over previously used pulsatile-flow LVADs, including improved durability, less surgical trauma, higher energy efficiency, and lower thrombogenicity. These benefits translate into better survival, lower frequency of adverse events, imp...

he advent of cardiopulmonary bypass (CPB) has enabled cardiovascular surgeons to perform complex, life-saving procedures with relative ease while protecting end-organ function. Altering the normal pulsatile blood flow to non-pulsatile continuous flow has raised concerns over potential detrimental hemodynamic and physiologic consequences. Concerns over long-term non-pulsatile flow drove the desi...
