Rapid progressive dysfunction of Carpentier-Edwards porcine valve model 6625

Abstract

In 11 cases of 28 recent re-MVR (group A), the same type of PTF of Carpentier-Edwards porcine valves by detaching the two cusps as a mass from the strut without showing calcification (PTF type A) were found. Re-MVR was performed earlier after the onset of PTF (0.9±0.6 months)in these patients including 4 emergency operations than the cases of other type of PTF(p<0.01). Pathologically collagen degradation and cusp detachment from the strut leaving the suture thread at the strut side were detected.
