Ablation of Atrial Fibrillation in a Patient with Dilated Cardiomyopathy

Gustavo Maid, Raúl Perez Etchepare, Sebastían Maldonado, Rodolfo Pizarro



This presentation describes a patient of 57 years, hospitalized for progressive congestive heart failure. The electrocardiogram showed atrial fibrillation of high ventricular response and the echocardiogram revealed dilated cardiomyopathy with severe impairment of the left ventricular function and severe mitral regurgitation without organic valvular compromise. Coronary artery disease was ruled out. Radiofrequency ablation was presented as the best alternative for his condition.

The patient recovered sinus rhythm, with which he remains since last 2 years, with asymptomatic evolution and improvement of all echocardiographic parameters.



Invasive treatment of atrial fibrillation in patients with dilated cardiomyopathy with suspicion of tachycardiomyopathy represents a difficult and controversial decision.
