Mid-term results of aortic root repair using the reimplantation technique: our single-center experience

Amaç: Bu çalışmada reimplantasyon tekniği kullanılarak kapak koruyucu aort kök replasmanının erken ve orta dönem sonuçları bildirildi.Ça lış ma pla nı: Ocak 2008 - Haziran 2015 tarihleri arasında, tek merkezde tek cerrah tarafından David-V tekniği kullanılarak kapak koruyucu aort kök replasmanı yapılan toplam ardışık 54 hasta (44 erkek, 10 kadın; ort. yaş 58±12.3 yıl; dağılım 26-80 yıl) retrospektif olarak incelendi.Bul gu lar: Hastane içi mortalite oranı %1.9 idi. Medyan takip süresi 57.5 ay idi. Cerrahinin ilk yılında iki hastada şiddetli aort yetmezliği gelişti ve aort kapak replasmanı yapıldı. Bir, beş ve yedinci yılda tahmini sağkalım oranı sırasıyla %96.2±0.03, %96.2±0.03 ve %96.2±0.03 idi. Orta ila şiddetli aort yetmezliği olmaksızın sağkalım oranı bir, beş ve yedinci yılda sırasıyla %96.2±0.03, %96.2±0.03 ve %96.2±0.03 idi. Bir, beş ve yedinci yılda yeniden kapak ameliyatı olmaksızın sağkalım oranı sırasıyla %96.2±0.03, %96.2±0.03 ve %96.2±0.03 idi.So nuç: Kapak koruyucu aort kök reimplantasyon işlemlerimizin erken ve orta dönem sonuçları mükemmeldir.

Reimplantasyon tekniği kullanılarak yapılan aort kök tamirinin orta dönem sonuçları: Tek merkezli çalışma deneyimimiz

Background: This study aims to report early and midterm results of valve-sparing aortic root replacement using the reimplantation technique.Methods: A total of 54 consecutive patients (44 males, 10 females; mean age 58±12.3 years; range 26 to 80 years) who underwent valve-sparing aortic root replacement using the David-V technique performed by a single surgeon at a single center between January 2008 and June 2015 were retrospectively analyzed.Results: The in-hospital mortality rate was %1.9. The median follow-up was 57.5 (range, 29.5 to 77) months. Two patients developed severe aortic insufficiency during the first year following surgery and underwent aortic valve replacement. Estimated survival rates were 96.2±0.03%, 96.2±0.03% and 96.2±0.03% at one, five, and seven years, respectively. Moderate to severe aortic insufficiency-free survival rates were 96.2±0.03%, 96.2±0.03% and 96.2±0.03% at one, five, and seven years, respectively. Survival rates free from valve related re-operation at one, five, and seven years were 96.2±0.03%, 96.2±0.03% and 96.2±0.03% respectively.Conclusion: Our early and mid-term results of the valvesparing root reimplantation procedures for aortic root aneurysms are excellent.
