Objective: Epicardial fat tissue is known to be arrhythmogenic. In this study we aimed to evaluate if this arrhythmogenic effect affects cardioversion (CV) success in patients with atrial fibrillation (AF).

Materials and Method: We studied 100 AF patients treated with CV in order to restore sinus rhythm. Patients were divided into two groups;  Group 1 patients were successfuly restored sinus rhythm and group 2 were failed to restore sinus rhythm. Demographic characteristics of study population, standard 2 dimensional Doppler and tissue Doppler echocardiographic findings were recorded.

Results: There were 94 patients (59.5±14.1, years) in group 1 and 6 patients (59±8.7, years) in group 2. There were no differences between the two groups in terms of patient demographics. Basic echocardiographic parameters suchas left atrial diameter, left ventricular diameter, septal thicness, ejection fraction, and left ventricular mass index were also similar between two groups. Epicardial fat thickness (EFT) was higher in group 2 patients (p=0.002).

Conclusion: Increased epicardial fat thickness found to be related with reduced CV success rates in the AF patients.

Amaç: Epikardiyal yağ dokusunun aritmojenik etkileri bilinmektedir. Bu çalışmada bu aritmojenik etkinin kardiyoversiyon (KV) başarısı üzerine olan etkisinin araştırılması amaçlanmıştır.



Gereç ve Yöntemler: Çalışmaya sinüs
ritminin sağlanması amacıyla KV uygulanan 100 atriyal fibrilasyon (AF) hastası
alınmıştır. Hastalar iki gruba ayrıldı; 
sinüs ritmi sağlanan hastalar grup 1, sağlanamayan hastalar grup 2 olarak
değerlendirildi.  Çalışma popülasyonunun
karakteristik özellikleri, standart 2 boyutlu ekokardiyografik ölçümler ve doku
doppler ölçümleri kaydedildi.



Bulgular:
G
rup
1’de 94 ( ortalama yaş 59,5+-14,1) grup 2’de 6 
(ortalama yaş 59+-8,7) hasta vardı. Temel hasta özellikleri açısından
gruplar arasında fark yoktu. Sol atriyum çapı, sol ventrikül çapları, septal
duvar kalınlıkları, ejeksiyon fraksiyonu ve sol ventrikül kitle indeksi gibi
ekokardiyografik parametreler açısından her iki grup benzerdi. Epikardiyal yağ
kalınlığı (EYK) grup 2 hastalarda daha yüksekti (p=0,002).



Sonuç: Artmış EYK, AF
hastalarında KV başarı oranlarında azalma ile ilişkili bulunmuştur.
