Hybrid epicardial and endocardial catheter ablation in a patient with atrial fibrillation and suspicious left atrial thrombus.

摘要: Patients with a left atrial (LA) thrombus are considered at risk of serious thromboembolic event, and therefore endocardial radiofrequency catheter ablation (RFCA) fibrillation (AF) is contraindicated. However, RFCA AF inevitable in some patients highly symptomatic suspicious LA masses resembling thrombus. A patient was treated who underwent hybrid epi- for drug resistant, symptomatic, paroxysmal that lamellated, thickened, echogenic lesion attached to the anterior wall resistant anticoagulation. During RFCA, contact endocardium minimized using guided by computed tomography merged 3-dimensional electroanatomical mapping (NavX). The has been free without antiarrhythmic drugs 6 months, may be an effective therapy mass. (Circ J 2009; 73: 384 - 387)
