BACKGROUND: There is a paucity of data evaluating the effect of performing a concomitant cardiac procedure (CCP) on peri-operative survival in patients undergoing implantation of long-term left ventricular assist devices (LVADs). The objective of this study was to review our single-institutional experience with patients who underwent a CCP during implantation of a long-term continuous-flow LVAD. METHODS: From March 2006 through June 2012, 130 patients underwent implantation of a LVAD. Of these, 76 (58.5%) were implanted as bridge-to-transplant and 54 (41.5%) as destination therapy. The LVAD implantation was isolated in 95 patients and with CCP in 35. This included 19 tricuspid valve repairs, 14 aortic valve repair/replacements, and 2 patent foramen ovale closures. The LVAD only and LVAD+CCP groups were compared regarding pre-operative demographics, peri-operative and midterm survival, and the incidence of post-operative complications. RESULTS: Pre-operative central venous pressure (p = 0.047), moderate to severe tricuspid regurgitation (p = 0.011), cardiopulmonary bypass time (p < 0.0001), cross-clamp time (p < 0.0001), and right ventricular end diastolic diameter (p = 0.039) were higher in the CCP group. Body mass index (p = 0.01) and body surface area (p = 0.037) were higher in the LVAD-only group. Peri-operative and midterm survival at 30 days, 6 months, 1 year, and 2 years was 94%, 87%, 80%, and 73%, respectively, for isolated LVAD implants vs. 97%, 90%, 86%, and 86%, respectively, for LVAD+CCP (p = NS). Survival was similar for LVAD patients with tricuspid valve repairs, with aortic valve repair, and with patent foramen ovale repair (p = NS). Cox proportional hazard models showed a CCP was not an independent predictor of outcome (p = NS). CONCLUSIONS: CCPs performed during implantation of a long-term continuous-flow LVADs does not increase peri-operative or mid-term mortality. In addition, unlike previous reports, there was no additive procedural risk for patients undergoing concomitant aortic valve repair or replacement.
