Abstract

This report is a description of a rare case oftransient ST-segment elevation during cryoballoon application for paroxysmal atrial fibrillation (PAF). A 74-year-oldmale with symptomatic PAF was referred to the center forablation. During cryoablation of the left superior pulmonaryvein (188 seconds, -48°C), ST-segment elevation in theanterolateral leads was observed suddenly, though without any significant complaint. Upon the increase in the STsegment, the cryoapplication was immediately terminated.Coronary artery angiography was performed less than 5minutes after balloon deflation and demonstrated coronaryslow flow with a corrected Thrombolysis In Myocardial Infarction (TIMI) frame count of 48.4 (normal range: 21±3)in the left anterior descending artery (LAD). There was nosignificant flow-limiting lesion, coronary vasospasm, thromboembolus, or air embolus in any coronary vessel. The TIMIframe count for the right coronary artery and the circumflexartery was normal. The ST-segment elevation gradually returned to the baseline in 14 minutes without any intervention. A control TIMI frame count of the LAD was 22. A decision was made not to repeat the cryoapplication in this veinbecause there was both an entrance and an exit block. Theother 3 pulmonary veins were then isolated uneventfully.The patient was discharged from the hospital the next daywithout symptoms or unusual electrocardiogram activity.

Özet

Burada, paroksismal atriyum fibrilasyonu (PAF) için kriyobalon uygulaması esnasında geçici ST segment yükselmesi yaşayan nadir bir olguyu sunduk. Şikayete yol açan PAF’lı 74 yaşındaki erkek hasta, ablasyon için merkezimize yönlendirildi. Sol üst pulmoner venin (188 saniye, -48°C’de) kriyobalon ile ablasyonu sırasında, herhangi bir ciddi yakınma olmaksızın anterolateral derivasyonlarda ST segment yükselmesi geliştiği gözlendi. ST segment yükselmesinin artması üzerine kriyobalon uygulaması derhal sonlandırıldı. Balonun indirilmesinin ardından 5 dakikadan daha kısa bir sürede koroner arter anjiyografisi yapıldı ve sol ön inen arterde (LAD) 48.4 (normal aralık 21±3) düzeltilmiş Thrombolysis In Myocardial Infarction (TIMI) kare sayısı ile koroner yavaş akım (KYA) gösterildi. Herhangi bir koroner arterde akımı kısıtlayıcı ciddi lezyon, koroner vazospazmı, trombo-emboli ya da hava embolisi mevcut değildi. Sağ koroner arter ve sirkumfleks arterin TIMI kare sayıları normaldi. Herhangi bir girişime gerek kalmaksızın ST segment yükselmesi 14 dakika içerisinde tedricen başlangıç haline döndü. Sol ön inen arterin kontrol TIMI kare sayısı 22 ölçüldü. Giriş ve çıkış bloğu zaten sağlandığından bu vene tekrar kriyobalon uygulaması yapılmadı. Diğer üç ven olaysız bir şekilde izole edildi. Hasta ertesi gün belirti ve elektrokardiyogram değişikliği olmadan hastaneden taburcu edildi.
