  • Title: Impact of pulmonary vein isolation on left bundle branch block following tachycardia-induced cardiomyopathy in a patient with persistent atrial fibrillation.
    Author: Senoo K, Otsuka T, Suzuki S, Sagara K, Yamashita T.
    Journal: Intern Med; 2014; 53(7):721-4. PubMed ID: 24694484.
    Abstract:
    A 61-year-old man was referred to our hospital with exertional dyspnea. Electrocardiography showed atrial fibrillation (AF) with a heart rate of 116 bpm and left bundle branch block (LBBB). Chest radiography demonstrated pulmonary congestion and cardiomegaly with a cardiothoracic ratio of 57%. Transthoracic echocardiography revealed a severely reduced left ventricular systolic function (ejection fraction: 32%), suggesting tachycardia-induced cardiomyopathy (TIC) due to AF. Following treatment for congestive heart failure and complete isolation of each pulmonary vein, the LBBB disappeared, with a complete recovery of the cardiac systolic function. This report describes a case of transient reversible LBBB associated with systolic dysfunction treated with catheter ablation.
