Abstract

The Jarvik 2000 bridge to transplant investigational device exemption study was a multicentered, prospective study of 150 UNOS status I patients implanted with the Jarvik 2000 between 2005 and 2012. During the study period, there were numerous modifications of the system that included converting from pin to cone bearings. Results were analyzed for three cohorts: total (n = 150), pin (n = 128), and cone (n = 22). Baseline demographics included age (52 ± 13), gender (79% male), size (BSA 1.98), and etiology (37% idiopathic dilated cardiomyopathy; 43% Ischemic). Seventy percent of patients were either INTERMACS 1 or 2. The primary endpoint - defined as successful transplantation or listing at 180 days (prespecified at 65%; 95% lower CI: 57%) - was successfully achieved for the total cohort (67.3%; 95% CI: 59.5%-74.3%; p = 0.006). In subgroup analysis of the more contemporary, cone-bearing group, the primary endpoint was met in 91% (95% CI: 72%-97.5%; p = 0.001). Compared with pin patients, cone-bearing patients had less hemolysis as well as decreased end-organ dysfunction. Functional and quality of life scores improved after implantation independent type of bearing. In conclusion, despite a particularly sick patient population, the Jarvik 2000 was shown to be effective in supporting the advanced HF patient.
