Abstract

ackground: The aim of the current study was to compare hemodynamic performances of the Carbomedics® and On- X® mechanical bileaflet heart valves in the early postoperative period in patients undergoing mitral valve replacement (MVR).Methods: Thirty patients who underwent MVR operations were randomly divided into two groups. Carbomedics® and On-X® mechanical bileaflet mitral valves were implanted in the first group (n=15) and the second group (n=15) of patients, respectively. Hemodynamic measurements were done by echocardiography in the preoperative period and three months after the operation.Results: There were no statistically significant differences between the two groups regarding pre- and postoperative changes that occured in left ventricular end diastolic diameter, left ventricular end sistolic diameter, left atrium diameter, pulmonary artery pressure, ejection fraction and fractional shortening (p>0.05). However, performance index in the Carbomedics® group was higher than that in the On-X® group (0.96±0.15 vs 0.73±0.10) and the difference was statistically significant (p 0.05).Conclusions: When echocardiographic data of the On-X® and Carbomedics® mitral mechanical heart valves were compared in the early postoperative period, similar hemodynamic performances were found. We propose that the On-X® heart valve, which has been introduced into clinical use more recently than Carbomedics®, can be used safely in MVR operations.

Özet

Amaç: Bu çalışmanın amacı, mitral kapak replasmanı (MVR) ameliyatı yapılmış hastalarda Carbomedics® ve On-X® marka mekanik bileaflet kalp kapaklarının hemodinamik performanslarının ameliyat sonrası erken dönemde karşılaştırılmasıdır.Çalışma planı: Mitral kapak replasmanı ameliyatı yapılan 30 hasta rasgele olarak iki ayrı gruba ayrıldı. İlk gruptaki hastalara (n=15) Carbomedics®, diğer gruptaki hastalara da (n=15) On-X® marka mekanik bileaflet mitral kalp kapağı takıldı. Ameliyat öncesi dönemde ve ameliyattan üç ay sonra ekokardiyografi ile hemodinamik ölçümler yapıldı.Bulgular: Sol ventrikül diyastol sonu çapı, sol ventrikül sistol sonu çapı, sol atrium çapı, pulmoner arter basıncı, ejeksiyon fraksiyonu ve fraksiyonel kısalma için ameliyat öncesi ve sonrası dönem arasında gelişen değişiklik açısından iki grup karşılaştırıldığında istatistiksel olarak anlamlı fark yoktu (p>0.05). Ameliyat sonrası dönemde ise, Carbomedics ® grubuna ait performans indeksi değeri On-X® grubuna göre daha yüksekti (0.96±0.15'e karşın 0.73±0.10) ve fark istatistiksel olarak anlamlı bulundu (p 0.05).Sonuç: On-X® ve Carbomedics® mekanik mitral bileaflet kalp kapaklarının ameliyat sonrası erken dönemde benzer hemodinamik performanslara sahip olduğu görüldü. Carbomedics® ile kıyaslandığında klinik kullanıma yeni girmiş olan On-X® mekanik kalp kapağının, MVR ameliyatlarında güvenle kullanılabileceği düşüncesindeyiz.
