Abstract

<p><b><i>Background: </i></b>The aim of this single-center study was to report the midterm clinical outcomes and hemodynamic performance of the St Jude Medical Epic porcine bioprosthesis, a tricomposite glutaraldehyde-preserved porcine bioprosthesis, in mitral position. </p><p><b><i>Methods and Results: </i></b>Between January 2011 and March 2017, 117 patients (62 men, 55 women; mean age, 66.7±12.8 years) who underwent mitral valve replacement (MVR) with the Epic valve were retrospectively analyzed for early and mid-term morbidity and mortality. The mean follow-up period was 2.6±1.7 years. Three operative deaths occurred, and the operative mortality rate was 2.6%. Sixteen patients died during the follow-up period. On Kaplan-Meier analysis, freedom from all-cause death and major adverse cardiovascular and cerebrovascular events at 5-year follow-up were 80.9% and 54.8%, respectively. There were 6 reoperations: 2 for structural valve deterioration (SVD), 2 for prosthetic valve endocarditis, and 2 for thrombosis. Freedom from valve-related reoperation and SVD at 5 years were 89.0% and 93.1%, respectively. On multivariate analysis, age ≥71 years (HR, 6.78; 95% CI: 2.12–25.2, P<0.01), and NYHA functional class ≥III (HR, 3.20; 95% CI: 1.03–10.4, P=0.04) were independent predictors for all-cause death. Mean mitral pressure gradient at 1 year and 2 years were 5.1±1.9 mmHg and 4.5±1.4 mmHg, respectively. </p><p><b><i>Conclusions: </i></b>Mid-term clinical results and durability of the Epic valve in the mitral position are satisfactory. </p>
