Hemodynamic performance of the St. Jude Medical Epic Supra aortic stented valve.

Abstract

The results of the six-month echocardiographic follow up indicated that the Epic Supra valve offered excellent hemodynamic performance in the 21, 23 and 25 mm sizes. However, additional data are still required for the 19 and 27 mm valves to characterize their performance. The mean gradients and EOA-values were comparable to those of other supra-annular stented tissue valves. The EOA index indicated an absence of prosthesis-patient mismatch, with values in all subjects at or near 0.85 cm2/m2. The percentage of subjects without aortic insufficiency (AI) at follow up was 92%; only four subjects showed trivial AI.
