The aim of this study was to highlight some of the hemodynamic and echocardiographic parameters we observed in patients who recovered.Methods: We conducted a retrospective analysis of 7 patients who received the HeartMate II LVAD (Abbott) at Temple Heart and Vascular Institute and subsequently underwent successful explantation following myocardial recovery. We compared baseline characteristics, echocardiographic data, and hemodynamic data.Results: Baseline characteristics of the cohort were as follows: age 51.6 {\textpm} 12.0 years, 57.1\% male, 42.9\% with nonischemic cardiomyopathy, and mean duration of LVAD support of 10.6 months. Comparison of echocardiographic and hemodynamic data (preimplant vs preexplant) revealed the following: left ventricular ejection fraction (\%) was 12.8 {\textpm} 6.9 vs 52.8 {\textpm} 8.1 (P=0.0001), right atrial pressure (mmHg) was 12.3 {\textpm} 3.4 vs 5.0 {\textpm} 4.0 (P=0.022), mean pulmonary artery pressure (mmHg) was 36.0 {\textpm} 7.8 vs 15.4 {\textpm} 7.1 (P=0.01), cardiac output (L/min) was 3.6 {\textpm} 1.3 vs 5.5 {\textpm} 1.8 (P=0.004), and cardiac index (L/min/m2) was 1.8 {\textpm} 0.5 vs 2.7 {\textpm} 0.7 (P=0.008). Mean LVAD-free survival was 49.1 months. Results were consistent in both ischemic and nonischemic LVAD explants.Conclusion: A potential for LVAD explantation exists in patients with both ischemic and nonischemic cardiomyopathy. Myocardial recovery may be more likely among young patients with nonischemic cardiomyopathy and patients with recently diagnosed ischemic cardiomyopathy.
