Abstract

Objective: The aim of the study is to find out the efficacy of radiofrequency catheter atrial ablation (RF) simultaneously done with mitral valve replacement (MVR) surgery in patients having rheumatic mitral valve disease with chronic atrial fibrillation and to evaluate the short-term postoperative results. Methods: Seventeen patients underwent MVR surgery, and intraoperative RF were done simultaneously to eight of these patients whereas remaining nine of them were assigned to control group. Patients were assessed preoperatively, at time of discharge, and 1th, 6th and 12th months controls. Atrial and ventricular functions were evaluated with echocardiography, serum atrial natriuretic peptide (ANP) levels were investigated and electrocardiograms were recorded in all patients. Results: Demographically there were no significant differences between two groups. Radiofrequency ablation group had longer aortic cross-clamping and cardiopulmonary bypass times. Sinus rhythm was established in seven patients of RF group at postoperative 12th month. However, all patients of this group experienced sinus rhythm at postoperative sixth month whereas 'atrial kick' was detected in five of them. Significantly increased ejection fraction, decreased pulmonary artery pressure and decreased left atrial diameter were observed in RF group compared to control group. Serum ANP levels were found to be significantly decreased as compared to preoperative periods in both groups. Conclusion: Although RF ablation has higher costs, this technique is efficient and useful to restore the sinus rhythm and to recover the atrial functions back in patients having rheumatic mitral valve disease.

Özet

Amaç: Kronik atriyal fibrilasyonu olan romatizmal mitral kapak hastalarında mekanik mitral kapak replasmanı (MKR) uygularken eş zamanlı atriyal radyofrekans ablasyon (RF) yapılmasının sonuçları ve hastanın prognozuna olan etkileri incelendi. Yöntemler: On yedi hastaya mitral kapak hastalığı nedeniyle MKR uygulandı. Hastaların sekizine operasyon sırasında eş zamanlı RF uygulanırken kalan dokuz hasta kontrol grubunu oluşturdu. Hastalar pre- ve postoperatif dönemdeki verileri incelendi, 1., 6. ve 12. aylarda kontrolleri yapılıp her iki grup birbirleri ile karşılaştırıldı. Atriyal ve ventriküler fonksiyonlar, elektrokardiyografik (EKG) ve ekokardiyografik veriler, serum atriyal natriüretik peptid (ANP) düzeyleri değerlendirildi. Bulgular: Her iki grup arasında demografik veriler açısından anlamlı fark yoktu. Radyofrekans ablasyon uygulanan hasta grubunda aortik kros-klemp zamanı ve kardiyopulmoner baypas zamanı daha uzundu. Postoperatif dönemde idrar ''output'' düzeyi, diüretik ihtiyacı, kanamaya bağlı reoperasyon oranı, perikardiyal effüzyon varlığı, yoğun bakım ve hastanede kalış süresi her iki grup arasında anlamlı fark yoktu. Postoperatif 6. ve 12. ay değerlendirmelerinde RF uygulanan tüm hastalarda EKG'de sinüs ritmi izlendi. Fakat bu hastaların yalnızca beşinde ''atrial kick'' mevcuttu. Ejeksiyon fraksiyonunda artma, pulmoner arter basıncında normale dönme ve sol atriyal çapta azalma RF grubunda diğer gruba oranla anlamlı olarak daha sık gözlendi. Her iki grupta da serum ANP düzeyleri preoperatif dönemle karşılaştırıldığında anlamlı olarak düşük bulundu. Sonuç: Atriyal radyofrekans ablasyonun maliyeti daha fazla olmasına rağmen bu teknik, romatizmal kökenli mitral kapak hastalarında MKR sonrası sinüs ritminin ve atriyal fonksiyonların geri dönmesinde etkili ve yararlı bir yöntemdir.
