Short-term follow-up results of percutaneous mitral balloon valvuloplasty: A single-center experience

Öz

Objective: We sought to analyze short-term clinical, echocardiographic, and hemodynamic consequences of percutaneous mitral balloon valvuloplasty (PMBV) in the treatment of rheumatic mitral stenosis (MS) in our clinic. Methods: We retrospectively reviewed 53 patients (49 females, 5 males; mean age 38±11 years) who underwent PMBV for moderate or severe MS between January 2010 and October 2014. Procedural success was defined as the reaching a mitral valve area (MVA) >1.5 cm2 and absence of grade 3 mitral regurgitation. Results: We were able to perform PMBV in 48 of 53 patients (91%) and all the procedures that were completed were successful. PMBV couldn\'t be performed in 3 patients due to inability to pass the mitral valve, 1 patient due to membranous obstructive vena cava and 1 patient due inability to perform septostomi. Two patients who underwent successful PMBV became symptomatic after an average of 14 months follow-up and mitral valve replacement was performed due to moderate-to-severe MS. Patients were followed for an average of 13 ± 8 months and atrial fibrillation development or embolic complications were not observed. Conclusion: Percutaneous mitral balloon valvuloplasty procedure is a safe and effective treatment approach with high success and low complication rates in experienced centers.

Öz

Amaç: Bu çalışmada kliniğimizdeki romatizmal mitral darlıklı (MD) erişkin hastalara uygulanan perkütan mitral balon valvüloplastinin (PMBV) erken dönem klinik, ekokardiyografik ve hemodinamik sonuçlarını değerlendirmeyi amaçladık. Yöntemler: Kliniğimizde Ocak 2010-Ekim 2014 tarihleri arasında orta ya da ciddi MD nedeniyle PMBV uygulanan 53 hasta (49 kadın, 5 erkek; ortalama yaş 38±11 yıl) geriye dönük olarak değerlendirildi. İşlem başarısı, işlem sonrası mitral kapak alanının (MKA) >1,5 cm2 olması ve 3. derece mitral yetersizlik (MY) olmaması olarak kabul edildi. Bulgular: Toplam 53 hastadan 48\'inde (%91) PMBV işlemi uygulanabildi ve tamamlanabilen tüm işlemler başarılı oldu. Hastalardan 3\'üne kapak geçilememesi, 1\'ine membranöz obstrüktif vena kava, 1\'ine de septostomi yapılamaması nedeniyle PMBV uygulanamadı. Başarılı PMBV uygulanan 2 hastaya ortalama 14 ay sonra semptomatik orta-ciddi MD nedeniyle mitral kapak replasmanı yapıldı. Ortalama 13±8 ay boyunca izlenen hastalarda atrial fibrilasyon gelişmesi veya embolik komplikasyonlar izlenmedi. Sonuç: Perkütan mitral balon valvüloplasti işlemi deneyimli merkezlerde yüksek başarı ve düşük komplikasyon oranları ile etkin ve güvenli bir tedavi yaklaşımıdır.
