The HeartMate II is an axial-flow left ventricular assist device that is approved for the treatment of advanced heart failure as a bridge to transplant or destination therapy. Despite the success of this device, right ventricular failure remains a persistent problem in most studies. Right ventricular dysfunction is usually defined as the need for right heart mechanical support or the persistent requirement for inotropes to support right heart function beyond 14 days. Over 21 months, 45 patients with end-stage heart disease underwent placement of the HeartMate II at our institution. This continuous cohort of patients underwent a retrospective review to evaluate the incidence of right heart failure. The perioperative survival was 91% with no incidents of mechanical support for the right ventricle and no requirements for inotropes beyond 14 days. This survival was consistent to beyond 1 year at the time of the study, and 18% of patients underwent heart transplant with 100% survival.

Significant hepatotoxicity due to allopurinol seems to be rare. Only 6 such cases have been recorded in the literature. The clinical and histopathologic findings of allopurinol-induced liver injury are variable in the previously reported cases. Described herein is another patient with allopurinol hepatotoxicity. Of interest is the similar histopathology between the present case and the two previously reported cases of allopurinol-induced granulomatous hepatitis; thus this is the third such recorded case. Allopurinol should be suspected when liver abnormalities occur following use of this drug.
