Early outcomes of the sutureless aortic valves versus conventional stented bioprosthetic valves

Amaç: Bu çalışmada, konvansiyonel stentli biyoprotez kapaklara kıyasla, dikişsiz aort kapakların erken dönem sonuçları karşılaştırıldı.Ça lış ma pla nı: Ekim 2009 - Mayıs 2014 tarihleri arasında 46 hasta (22 erkek, 24 kadın; ort. yaş 74.74±7.35 yıl; dağılım 56 to 87 yıl) çalışmaya dahil edildi. Grup 1'de konvansiyonel stentli biyoprotez kapak ile 25 hasta ve grup 2'de dikişsiz aort kapağı ile 21 hasta olmak üzere, hastalar iki gruba ayrıldı.Bul gu lar: Ameliyat sonrası maksimum aortik gradyan dikişsiz grupta 20.1±5.5 mmHg ve stentli grupta 28.7±13.9 mmHg idi (p=0.038). Ameliyat sonrası ortalama gradyan dikişsiz grupta 10.3±3.4 mmHg ve stentli grupta 15.1±8.4 mmHg idi (p=0.052). Dikişsiz grupta hastane mortalitesi gözlenmedi; ancak stentli grupta hastane yatışı sırasında beş hasta kaybedildi (p=0.054).So nuç: Dikişsiz aort kapak replasmanı, kısa iskemi süresi ile mükemmel hemodinamik koşullar sağlayan, yeni bir cerrahi tedavi yöntemidir.

Konvansiyonel stentli biyoprotez kapaklara kıyasla dikişsiz aort kapaklarının erken dönem sonuçları

Background: In this study, we compared the early outcomes of sutureless aortic valves versus conventional stented bioprosthetic valves.Methods: Between October 2009 and May 2014, 46 patients (22 males, 24 females; mean age 74.74±7.35 years; range 56 to 87 years) were included. The patients were divided into two groups including 25 patients with conventional stented bioprosthetic valves in group 1 and 21 patients with sutureless aortic valves in group 2.Results: The maximum postoperative aortic gradient was 20.1±5.5 mmHg for the sutureless group and 28.7±13.9 mmHg for the stented group (p=0.038). The mean postoperative gradient was 10.3±3.4 mmHg for the sutureless group and 15.1±8.4 mmHg for the stented group (p=0.052). No in-hospital mortality was seen in the sutureless group; however, five patients in the stented group died during the hospital stay (p=0.054).Conclusion: Sutureless aortic valve replacement is a novel surgical treatment modality, yielding excellent hemodynamic conditions with a short ischemic time.
