Abstract

Objectives: We compared Doppler echocardiographic features before and after radiofrequency catheter ablation (RFCA) performed for Wolff-Parkinson-White (WPW) syndrome in patients with and without atrial fibrillation (AF).Study design: Forty patients with WPW syndrome were evaluated in two groups depending on the presence of AF (6 females, 14 males; mean age 33±15 years) and atrioventricular reciprocating tachycardia (AVRT) (8 females, 12 males; mean age 32±18 years). Echocardiographic examination was performed in all the patients 24 hours before and after RFCA. Doppler parameters were recorded including E and A transmitral filling velocities and their velocity-time integrals (VTI), mitral diastolic filling time (mDFT), deceleration time, isovolumic contraction and relaxation times, aortic ejection time (ET) and aortic VTI.Results: The most common localization of the accessory pathway was the left lateral wall (n=9) in patients with AF, compared to one patient in the AVRT group. During programmed electrical stimulation, orthodromic AVRT was induced in all the patients with AVRT; of the AF group, six patients had AF and 14 patients exhibited AVRT that degenerated into AF. The two groups did not differ significantly before and after RFCA with regard to two-dimensional and Doppler echocardiographic parameters (p>0.05). Significant changes observed in both groups after RFCA were as follows: increases in A velocity and A wave VTI (p

Özet

Amaç: Atriyal fibrilasyonu (AF) olan ve olmayan Wolff-Parkinson-White (WPW) sendromlu hastaların, radyofrekans kateter ablasyonu (RFKA) öncesi ve sonrasındaki Doppler ekokardiyografik özellikleri karşılaştırıldı. Çalışma planı: Çalışmada WPW sendromlu 40 hasta AF varlığı (6 kadın, 14 erkek; ort. yaş 33±15) ve atriyoventriküler resiprokan taşikardi (AVRT) varlığına (8 kadın, 12 erkek; ort. yaş 32±18) göre iki grupta değerlendirildi. Tüm hastalarda RFKA işleminden 24 saat önce ve sonrasında ekokardiyografik inceleme yapıldı. Doppler parametreleri olarak, mitral kapağa ait E ve A dalga hızları ile bunların hız zaman integralleri (HZİ), mitral diyastolik doluş zamanı (mDDZ), deselerasyon zamanı, izovolümik kasılma ve gevşeme zamanları, aortik ejeksiyon süresi (EZ) ve aortik HZİ kaydedildi. Bulgular: Atriyal fibrilasyonlu grupta aksesuvar yol en sık sol lateral bölge (n=9) yerleşimliydi; AVRT’li grupta ise bu yerleşim bir hastada görüldü. Programlı elektriksel stimülasyon sırasında AVRT’li tüm hastalarda ortodromik AVRT indüklenirken, AF’li 14 hastada AVRT gelişti ve AF’ye dejenere oldu; diğer altı hastada AF meydana geldi. Gruplar arasında, ikiboyutlu ve Doppler ekokardiyografik parametreleri açısından RFKA öncesi ve sonrası dönemde anlamlı fark görülmedi (p>0.05). Ablasyon sonrasında iki grupta da A dalga hızında ve A dalgasına ait HZİ’de anlamlı artış (p
