Midterm results of aortic valve replacement with cryopreserved homografts

Amaç: Çalışmada kriyoprezerve homogreftler ile kapak replasman sonuçlarının orta dönem sonuçları incelenmiştir. Hastalar ve Yöntemler: Kriyopreserve homogreft ile 40 olguda aort kapak replasmanı yapıldı. Endikasyonlar; 20 olguda aort kapak endokarditi, 6 olguda truncus arteriosus ve 14 olguda aort kapak tamir prosedürü sonrası reoperasyonlardı. Kapak çapları 10-27mm idi. Tüm olgularda kök replasman tekniği kullanıldı. Bulgular: Operasyon sonrası 30 günlük mortalite oranı %12,5'ti. Geç dönemde 4 olgu kaybedildi. Sadece 1 olguda mortalite kardiyak nedenlere bağlıydı. Toplam mortalite oranı %22,5'ti. 33 olgu ortalama 67±26 aylık süreçte izlendi. Endokardite bağlı aort anevrizması nedeni ile 2 olgu tekrar ameliyat edildi. Replasman sonrası transvalvular gradiyentlerde istatistiksel anlamlı düşüş gözlendi (p

Kriyopreserve homogreft ile aort kapak replasmanı orta dönem sonuçları

Objective: The aim of this study was to analyze the midterm clinical results of aortic valve replacement with cryopreserved homografts. Materials and Methods: Aortic valve replacement was performed in 40 patients with cryopreserved homograft. The indications were aortic valve endocarditis in 20 patients (50%), truncus arteriosus in 6 patients (15%), and re-stenosis or regurtitation after aortic valve reconstruction in 14 (35%) patients. The valve sizes ranged from 10 to 27mm. A full root replacement technique was used for homograft replacement in all patients. Results: The 30-day postoperative mortality rate was 12.5% (5 patients). There were four late deaths. Only one of them was related to cardiac events. Overall mortality was 22.5%. Thirty-three patients were followed up for 67±26 months. Two patients needed reoperation due to aortic aneurysm caused by endocarditis. The mean transvalvular gradient significantly decreased after valve replacement (p
