Abstract

A 61-year-old woman with a low thromboembolic risk was scheduled to undergo pulmonary vein isolation (PVI) for paroxysmal atrial fibrillation. Transthoracic echocardiography showed no cardiac structural abnormality. Intracardiac echocardiography (ICE) identified a small left atrium mass attached to the atrial septum and the procedure was stopped before the transseptal puncture; the surgically resected tumor was cardiac myxoma. ICE is a reliable imaging modality to exclude left atrial thrombus. However, unusual and unexpected cardiac structures also prevent performing PVI, which pre-procedural transesophageal echocardiography could identify. Imaging options should be further discussed to improve patient care and safety.
