Rate of Thromboembolic and Bleeding Events in Patients Undergoing Concomitant Aortic Valve Surgery with Left Ventricular Assist Device Implantation

Background: Significant aortic regurgitation at the time of left ventricular assist device (LVAD) implantation, requires concomitant valve (AoV) replacement or repair. However, impact AoV surgery on morbidity remains unknown. Therefore, our aim is to determine thromboembolic and bleeding events. Methods: A retrospective IMACS registry study, including patients implanted from 2013 until September 2017. Differences between different modalities were analyzed. Results: In total, 785 (5.1%) out 15.267 (median age 58 IQR 49-66 years, 79% male) underwent 63 54-69 84% male); 386 (49%) received biological prostheses, 71 (9%) mechanical prostheses 328 (42%) repairs. 54 (8%) with experienced a event 1016 no surgery. Only repair was associated an increased rate pump thrombosis (p=0.024). Furthermore, all nonsurgical bleedings. Following multivariable Cox regression, remained independent predictor for events. Conclusions: LVAD undergoing surgery, rates not higher, however both higher. thrombosis.
