The Effect of Patient Prosthesis Mismatch on Functional Mitral Regurgitation in Patients with Mechanical Aortic Valve Replacement

Abstract

Introduction: The aim of this study was to investigate the effects of patient prosthesis mismatch on functional mitral regurgitation after mechanical aortic valve replacement. Patients and Methods: Total 59 patients were enrolled. All the echocardiographic assessments were performed by a single cardiologist. The patients were divided into two subgroups as per the presence of patient prosthesis mismatch. Group 1 comprised patients with mismatch, and group 2 included those without mismatch. Results: There were no significant differences between the two groups in terms of postoperative mitral regurgitation development, postoperative left ventricular mass regression, postoperative pulmonary arterial pressure, and postoperative functional capacity. Conclusion: Patient prosthesis mismatch is not a predictive factor for the development of functional mitral regurgitation after mechanical aortic valve replacement.

Mekanik Aort Kapak Replasmanı Yapılan Hastalarda Hasta Kapak Uyumsuzluğunun Fonksiyonel Mitral Yetmezliğine Etkileri

Abstract

Giriş: Bu çalışmanın amacı, hasta protez uyumsuzluğunun mekanik aort kapak replasmanı sonrası fonksiyonel mitral yetersizliği üzerine etkilerini araştırmaktır. Hastalar ve Yöntem: Çalışmaya 59 hasta dahil edildi. Tüm ekokardiyografik değerlendirmeler tek bir kardiyolog tarafından yapıldı. Hastalar, hasta kapak uyumsuzluğunun varlığına göre iki alt gruba ayrıldı. Grup 1, uyumsuzluğu olan hastalardan oluşurken, kalan hastalar uyumsuzluğu olmayan grup 2’yi oluşturdu. Bulgular: Postoperatif mitral yetmezlik gelişimi, postoperatif sol ventrikül kitle regresyonu, postoperatif pulmoner arter basıncı ve postoperatif fonksiyonel kapasite açısından iki grup arasında anlamlı fark yoktu. Sonuç: Hasta protez uyumsuzluğu, fonksiyonel mitral yetmezlik gelişimi için mekanik aort kapak replasmanı sonrası öngörücü bir faktör değildir.
