Abstract
graphic criteria: 1) pre-VAD implantation, 2) post-implantation, 3) longterm follow-up (238 184 days). Post-operative RV dysfunction was medically managed. Results: A significant improvement in TR resulted following VAD implantation (p 0.005) and was sustained long-term (p 0.005). Improvements in RV function were not immediately apparent, but improved significantly long-term following continuous flow VAD implantation (p 0.01). Significant improvements in mean pulmonary artery pressure (28 9 vs. 26 6 mmHg, p 0.01) and right ventricular stroke work index (5.9 3.3 vs 7.0 3.5 gm-m/m2/beat, p 0.05) were evident post-VAD implantation. 91% of patients were discharged (ICU LOS 8.4 7.4 days; hospital LOS 29 17 days). Conclusions: TR may be managed non-operatively during continuous flow VAD implantation. Severity of functional TR and RV dysfunction appear to improve following continuous flow VAD implantation.
