Characteristics of patients with Wolf Parkinson's White syndrome (WPW) ablation: Single center case series

Abstract

Aim:  Atrioventricular reentrant tachycardia (AVRT) formed by the presence of accessory pathway accounts for about one quarter of paroxysmal supraventricular tachycardias. In our retrospective study, demographic characteristics, etiological factors and complication rates of patients undergoing AVRT ablation were reported in a high-volume center where catheter ablation was performed.

Material and Methods: In our cardiology clinic, between January 2014 and January 2018, 1107 patients who underwent SVT ablation were screened and 232 WPW patients with catheter ablation were included in the study. These patients were evaluated in terms of their demographic characteristics, etiological factors, accessory path localizations, operation success and complication development.

Results: The mean age of the patients was 38 ± 16.1 and the female gender percentage was 37.1. The most common localization was found to be left  accessory origin (53.1%). While the complication rate was 3.3% in all patients, the most common complication was seen as a site of hematoma (2.1%).

Discussion:  Supraventricular tachycardia (SVT) is a group of diseases that can affect all age groups and can impair the quality of life. The second most common of this group is AVRT. Catheter ablation, is the known curative treatment of it. The number of physicians performing ablation treatment and the number of centers in which the procedure is performed increase. Our experience with AVRT ablation was reported with this study.

Wolf Parkinson White sendromu (WPW) ablasyonu yapılan hastaların özellikleri: Tek merkez vaka serisi

Abstract

Amaç: Aksesuar yol varlığı ile oluşan atriyoventriküler reentran taşikardiler (AVRT) paroksismal supraventriküler taşikardilerin yaklaşık dörtte birini oluşturur. Bizim retrospektif çalışmamızın amacı katater ablasyon işlemi yapılan yüksek volümlü bir merkezde, AVRT ablasyon yapılan hastaların demografik özellikleri, etiyolojik faktörler ve komplikasyon oranları hakkında bilgi vermektir.

Gereç ve Yöntemler: Hastanemizin kardiyoloji kliniğinde Ocak 2014 ve Ocak 2018 yılları arasında SVT ablasyonu uygulanan 1107 hasta tarandı ve katater ablasyon yapılmış 232 WPW ’li hasta çalışmaya dahil edildi. Bu hastalar demografik özellikleri, etiyolojik faktörleri, aksesuar yol lokalizasyonları, işlem başarısı ve komplikasyon gelişimi açısından değerlendirilmiştir.

    

Bulgular: Hastaların yaş ortalaması 38 ±16,1 olup ve kadın cinsiyet oranı %37.1 dir. En sık görülen lokalizasyonun sol aksesuar kaynaklı yolak olduğu görüldü(%53,1). Tüm lokalizasyonlar için akut dönemde işlem başarısı %93,1 saptandı. Tüm hastalarda karşılaşılan komplikasyon oranı % 3,3 iken, en sık karşılaşılan komplikasyon girişim yeri hematomu olarak karşımıza çıkmıştır(% 2,1).  

Tartışma: Tüm yaş gruplarını etkileyebilen ve yaşam kalitesini oldukça kötüleştirebilen bir hastalık grubu supraventriküler taşikardiler (SVT) dir. Bu grubun ikinci sıklıkta görülen üyesi AVRT’nin bilinen küratif tedavisi radyofrekans katater (RF) ablasyondur. Ablasyon tedavisi yapan hekim sayısı ve işlemin yapıldığı merkez sayısı giderek artış göstermektedir. Özellikle gelişebilecek komplikasyonlar açısından dikkat çekmek amaçlı AVRT ablasyon tecrübelerimiz bu çalışma ile sunulmuştur.
