Abstract

Some atypical right atrial flutters present as a double-loop reentry. This kind of arrhythmia usually occurs after a cardiac operation leaving behind a right atrial scar tissue, with one reentry loop turning around the tricuspid valve, and the other around the scar tissue. It is extremely difficult to detect the presence and localization of these reentry loops by conventional electrophysiologic studies. Only three-dimensional mapping techniques provide identification of these reentry loops. Herein, we presented a 55-year-old woman who developed persistent atrial flutter after mitral valve surgery. Conventional electrophysiologic study showed macroreentry in the right atrium, but ablation target could not be determined. With the use of a three-dimensional mapping technique, a double-loop reentry was delineated in the right atrium and ablation of the common isthmus resulted in the disappearance of tachycardia.

Özet

Atipik atriyal flutterlerin bir kısmı çift halkalı re-entri olarak karşımıza çıkmaktadır. Genellikle sağ atriyumda, skar dokusuna yol açan bir kalp ameliyatı sonrası ortaya çıkan bu aritmide, re-entri halkalarından biri triküspid kapak etrafında, diğeri ise skar dokusu etrafında dönmektedir. Aynı istmusu kullanan bu iki halkanın varlığı ve yerleşiminin konvansiyonel elektrofizyolojik yöntemlerle tanınması çok zordur. Bu tip aritmilerin tanınması ancak üçboyutlu haritalama yöntemleriyle mümkün olabilmektedir. Mitral kapak ameliyatı geçiren 55 yaşındaki kadın hastada, ameliyat sonrasında tedaviye dirençli bir atriyal flutter gelişti. Yapılan elektrofizyolojik çalışmada makro-re-entrinin sağ atriyumda yerleştiği görülmesine rağmen ablasyon hedefi belirlenemedi. Üçboyutlu haritalama sistemi rehberliğinde taşikardinin bir çift halkalı re-entri olduğu saptandı ve ortak istmusda iletimin ablasyon ile ortadan kaldırılması ile taşikardi kayboldu.
