Concomitant valve procedures in patients undergoing continuous flow left ventricular assist device implantation: A single center experience.
OBJECTIVE Long term support with continuous flow left ventricular assist devices (CF LVADs) has improved the outcomes of patients with end stage heart failure. However, valve disease management in patients who undergo CF LVAD implantation remains controversial. The aim of this study was to assess our single center experience with patients who underwent a concomitant valve procedure during implantation of a CF LVAD. METHODS From November 2003 through March 2016, 526 patients underwent primary CF LVAD implantation with a HeartMate II (St Jude Inc, St Paul, Minn; n 403) or HeartWare (Medtronic, Minneapolis, Minn; n 123) device at our center. Of those, 91 underwent a concomitant valve procedure during implantation (CF LVAD+valve procedure group) whereas 435 did not (CF LVAD only group) We compared preoperative characteristics and short term and mid term survival rates between these groups. RESULTS The concomitant valve procedures performed included 13 tricuspid valve repairs, 19 aortic valve repairs or replacements, 30 mitral valve repairs or replacements, and 29 double valve repairs or replacements. Survival rates at 1 month, 6 months, 12 months, and 24 months were 90.3% 81.4% 74.9% and 67.4% respectively, for the CF LVAD only group and 89.0% 75.8% 70.3% and 65.9% respectively, for the CF LVAD+valve procedure group (P .55) The results of Cox regression multivariable modeling showed that performing a concomitant valve procedure was not an independent predictor of mortality (hazard ratio, 1.29; 95% confidence interval, 0.96 1.74; P .08) CONCLUSIONS In our experience, performing a concomitant valve procedure during CF LVAD implantation was not associated with an increased mortality rate. The decision to perform a concomitant valve procedure should be made primarily on the basis of clinical indications for the procedure.
