Right Atrial Thrombus as a Complication of Supraventricular Tachycardia Ablation Resolved by Anticoagulation

Abstract

We present the case of a 40‐year‐old man who was found on routine echocardiography to have a right atrioventricular thrombus, 24 hours after succesful supraventricular trachycardia ablation he had undergone. With the patient being asymptomatic, coumarin anticoagulants were started, leading to complete clot resolution two weeks later. In this case, we stress the importance of routine echocardiography to identify thrombotic complications after ablation and we describe the course of a large right atrioventricular thrombus which was successfully treated with Vit K antagonists.

The diagnosis of right heart thrombus by focused cardiac ultrasound in a critically ill patient in compensated shock

“…The two major etiologies of RHT are embolic (due to propagation of a DVT) or in situ (due to stagnant blood flow, as seen in cardiomyopathy and in arrhythmia, such as in atrial fibrillation). However, there are case reports documenting RHT secondary to pacemaker wires [ 38 ], central venous catheters [ 39 ], hemodialysis catheters [ 40 ], and embryological remnants [ 41 ], as a complication of ablation [ 42 ], formed during cardiac arrest with cardiopulmonary resuscitation [ 43 ], and after carbon monoxide poisoning [ 44 ]. With regard to our patient, it is likely that the RHT development was multifactorial.…”

“…Tip B ise hareketsiz ve duvara yapışık olup daha iyi prognozludur (9) . Literatürde, son yıllarda artan kompleks perkütan ablasyon işlemleri sırasında sağ atriyum içerisinde oluşan pıhtı bildirimleri de mevcuttur (10) . Sağ atriyumdaki pıhtı tiplerinin farklı prognostik özelliklerine rağmen, tedavileri halen tartışma konusudur (1,5) .…”
