Posteriyor mitral liflet prolapsusunun Fundaro anüloplasti ile onarımı: Sütür anüloplasti teknikleri cerraha yardımcı olabilir mi?

Abstract

Amaç Fundaro anuloplasti, inferior miyokard enfarktüsü nedeniyle oluşan mitral yetmezlikte lifletlerin asimetrik bağlanması için geliştirilmiş bir posteriyor liflet onarım tekniğidir. Çalışmamızda fundaro anuloplasti tekniğinin operatif ve orta dönem sonuçlarımızı paylaşmayı amaçladık. Gereç ve Yöntemler Tip 3b mitral yetersizliği nedeniyle Fundaro anuloplasti uygulanan 30 hasta çalışmaya dahil edildi. Bu hasta grubundan 20 hastaya KABG ile birlikte Fundaro anuloplasti uygulandı, geri kalan 10 hastaya kombine işlemler uygulandı. Hastaların takiplerinde fizik muayene, elektrokardiyografi ve transtorasik ekokardiyografi yapıldı. Bulgular Çalışmaya alınan hastaların ortalama takip süresi 35,8±20,3 aydı (min:1 max:59). İntraoperatif yapılan TEE verilerine göre 24 (%80) hastada MY saptanmadı. Hastaların ameliyat sonrası ortalama takip süresi 35,8±20,3 aydı. İzlemde 23 (%76,7) hastada tekrarlayan MY izlenmedi. Postoperatif erken dönemde 2 (%6,7) hastada mortalite gelişti. Fonksiyonel kapasitelerinde anlamlı iyileşme gözlendi(p<0.001). Ortalama sol ventrikül diyastol sonu çapı, sol ventrikül sistol sonu çapı, sol atriyum çapı ve pulmoner arter basıncındaki düzelmeler ameliyat öncesi değerlere göre istatistiksel olarak anlamlı bulundu (p=0,001, p=0,001, p=0,007 ve p) = 0.001, sırasıyla). Sonuç Fundaro anuloplasti daha kısa XCL süresinde yapılabilmesi nedeniyle avantajlıdır. İskemiye bağlı mitral kapak yetmezliği olan hastalarda bu teknik ile onarım sonrası düşük nüks oranı ve ventriküler yeniden şekillenme üzerinde olumlu etkiler elde edilebilmektedir.

Correction of posterior mitral leaflet prolapse with Fundaro annuloplasty: Can suture annuloplasty techniques be helpful for surgeon?

Abstract

Aim Fundaro annuloplasty is a posterior leaflet repair technique developed for asymmetric tethering of mitral leaflets due to inferior myocardial infarction. ". In our study, we aimed to share our the operative and mid-term results of the fundaro annuloplasty technique. Material and Methods 30 patients who underwent Fundaro annuloplasty for type 3b mitral regurgitation were included in the study. Fundaro annuloplasty with CABG was performed in 20 patients from this patient group, the remaining 10 patients underwent combined procedures. During the flollow-ups of the patients, physical examination, electrocardiography and transthoracic echocardiography were performed. Results The mean follow-up period of the patients included in the study was 35.8±20.3 months (min:1 max:59). According to the TEE datas performed intraoperatively, MR was not detected in 24 (80%) patients. The mean postoperative follow-up period of the patients was 35.8±20.3 months. During the follow-up period, recurrent MR was not observed in 23 (76.7%) patients. Mortality developed in 2 (6.7%) patients in the early postoperative period. Significant improvement was observed in their functional capacities(p<0.001). Improvements in mean left ventricular end-diastolic diameter, left ventricular end-systolic diameter, left atrial diameter, and pulmonary artery pressure were found to be statistically significant when compared with preoperative values (p=0.001, p=0.001, p=0.007 and p=0.001, respectively). Conclusion Fundaro annuloplasty is an advantageous because it can be performed in shorter XCL time. Low recurrence rate after repair and positive effects on ventricular remodeling can be achieved with this technique in patient with mitral valve insufficiency due to ischemia.
