The Edwards MIRAtm Heart Valve Prosthesis:. A 2-Year Study

Abstract

These preliminary data suggest good hemodynamic function and a low rate of valve-related complications of the Edwards-MIRA mechanical prosthesis.

Long-term experience with the Sorin Bicarbon and Edwards Mira mechanical valve prostheses in the mitral position

“…Driever et al reported that the mean gradient of the EM valve in the mitral position was acceptably low (between 2.1 and 4.8 mmHg) and similar to that of the SB valve. 20 In the present study, echocardiographic examination confi rmed that both SB and EM valves showed an excellent hemodynamic performance in the mitral position. The function of the 23-mm valve was not evaluated in this study.…”

“…18 The EM valve has only short-term data for comparison with other mechanical valves. 19,20 In the present study, the combined population of SB and EM valves in the mitral position showed an actuarial freedom from death of 85.1% ± 4.8% at 9 years. This result is consistent with other mechanical valves, although our patients were not only a single mitral valve cohort.…”

“…9,19,20 Driever et al acknowledged that the sewing ring's exceptional compressibility enhances coaptation in highly calcifi ed annuli, and that the broad zone of the sewing ringannulus interface and the cushion-like quality of the ring are designed to accommodate even the most fragile tissue. 20 Furthermore, Remadi et al reported that no signifi cant paravalvular leakage was found with this valve in the aortic position. 9 We also found no paravalvular leakage in any patients during the follow-up period.…”
