Outflow cannula occlusion is an infrequent complication occurring among recipients of continuous flow left ventricular assist devices. Hereby, we present a case of a 66-year-old man with a HeartMate 3 left ventricular assist device that presented 18 months after implantation and during his admission, evidence of poor left ventricular unloading and forward flow uncovered intrinsic and extrinsic outflow cannula obstruction. The patient’s course was complicated by cardiogenic shock, diffuse alveolar hemorrhage and multiorgan failure. Post-mortem examination suggested foreign body reaction as a potential contributor of outflow graft obstruction at the level of the bend relief.

Abstract OBJECTIVES Tricuspid regurgitation (TR) is common in patients receiving a left ventricular assist device (LVAD). Controversy exists as to whether concomitant tricuspid valve surgery (TVS) is beneficial in currently treated patients. Therefore, our goal was to investigate the effect of TVS concomitant with a LVAD implant. METHODS The European Registry for Patients with Mechanical Circulatory Support was used to identify adult patients. Matched patients with and without concomitant TVS were compared using a propensity score matching strategy. RESULTS In total, 3323 patients underwent LVAD implantation of which 299 (9%) had TVS. After matching, 258 patients without TVS were matched to 258 patients with TVS. In the matched population, hospital deaths, days on inotropic support, temporary right ventricular assist device implants and hospital stay were comparable, whereas stay in the intensive care unit was higher in the TVS cohort (11 vs 15 days; P = 0.026). Late deaths (P = 0.17), cumulative incidence of unexpected hospital readmission (P = 0.15) and right heart failure (P = 0.55) were comparable between patients with and without concomitant TVS. In the matched population, probability of moderate-to-severe TR immediately after surgery was lower in patients with concomitant TVS compared to patients without TVS (33% vs 70%; P = 0.001). Nevertheless, the probability of moderate-to-severe TR decreased more quickly in patients without TVS (P = 0.030), resulting in comparable probabilities of moderate-to-severe TR within 1.5 years of follow-up. CONCLUSIONS In matched patients, TVS concomitant with LVAD implant does not seem to be associated with better clinical outcomes. Concomitant TVS reduced TR significantly early after LVAD implant; however, differences in probability of TR disappeared during the follow-up period.
