Abstract (2. Language): 
Objective: The aim of this study is to investigate the effecti-veness of unipolar radiofrequency ablation in patients with persistent atrial fibrillation undergoing mitral valve replace-ment. Method: Our study consists of 22 patients, who performed mitral valve replacement with associated left atrial ablation in our clinic between January 2010 and January 2012. Pos-toperative early and mid-term follow-up of the patients were retrospectively evaluated with 12-lead electrocardiog-raphic recordings. The patients were followed up during 6-month period. Results: After cardiopulmonary bypass, 14 (63.6%) patients maintained normal sinus rhythm, 8 patients including one patient with a temporary pace support has AF on time recei-ved to the intensive care unit. In the early period, one pati-ent died due to low flow, and prolonged intubation. At the end of the first month, 15 (71.4 %) patients were in sinus rhythm, and 6 patients (28.6%) were with atrial fibrillation persisted. Followed by the tenth postoperative atrial fibrilla-tion in a patient was implanted permanent pace. At follow-up 6th month, there was recurrent atrial fibrilla-tion.Conclusion: The success achieved with the unipolar radiofrequency left atrial ablation was found to be consis-tent with the findings of the literature. In our study, patient age and pulmonary hypertension was evaluated as predicti-ve of ongoing postoperative AF.

Özet Abstract Amaç: Bu çalışmanın amacı mtiral kapak replasmanı uygula-nan persistan atriyal fibrilasyonlu (AF) hastalarda unipolar radyofrekans ablasyon etkinliğinin araştırılmasıdır. Yöntem: Çalışmamıza, Ocak 2010- Ocak 2012 tarihleri ara-sında kliniğimizde mitral kapak replasmanı uygulanan ve beraberinde sol atriyal ablasyon uygulanan 22 hasta dahil edildi. Hastaların postoperatif ve orta dönem kontrol 12 derivasyonlu EKG kayıtları geriye dönük olarak değerlendiril-di. Hastaların operasyon sonrası 6 ay boyunca takip edilmesi planlandı. Bulgular: Kardiyopulmoner bypass çıkışında 14 (%63,6) hastada normal sinüs ritmi sağlandı, 1 hasta geçici pace desteğinde olmak üzere 8 (36,3) hasta AF ile yoğun bakıma alındı. Erken dönemde 1 hasta düşük debi ve uzamış entü-basyon nedeniyle kaybedildi. 1.ay sonunda 15 hasta (%71,4) sinüs ritminde, 6 hastada (% 28,6) atriyal fibrilasyon devam etmekteydi. Atriyal fibrilasyon ile takip edilen bir hastaya postoperatif 10. ayında kalıcı pace implante edildi. 6.ay sonunda tekrarlayan atriyal fibrilasyon olmadı. Sonuç: Sol atriyal unipolar radyofrekans ablasyon tedavisin-de elde edilen başarı literatür bulguları ile uyumlu olarak bulundu. Çalışmamız sonucunda, hasta yaşı ve pulmoner hipertansiyon postoperatif devam eden AF için prediktif olarak değerlendirilmiştir.
