Abstract

INTRODUCTION: Echocardiographic parameters for predicting cardioversion (CV) outcome and long-term sinus rhythm (SR) maintenance in patients with nonvalvular atrial fibrillation (AF) are not accurately defined. AIMS: The authors aim was to evaluate the role of left atrial appendage (LAA) flow velocity detected by transesophageal echocardiography before CV for prediction of short and long-term (1 year) outcome of CV in patients with nonvalvular AF. METHODS: One hundred and nine patients (66 males, mean age: 57 +/- 13 years) with nonvalvular AF lasting more than 48 hours but less than 1-year duration underwent transthoracic and transesophageal echocardiography before either electrical or pharmacological CV attempt. RESULTS: Cardioversion was successful in restoring SR rhythm in 83 (76%) and unsuccessful in patients 26 (24%). Mean LAA peak emptying flow was higher in patients with successful than in those with unsuccessful CV (36.7 +/- 14.7 vs 26.3 +/- 9.2 cm/sec; p <0.01). At multivariate analysis the left LAA emptying velocity > 32 cm/sec was the only independent predictor of CV success. Seventy-four out of the 83 patients with successful CV had a complete follow-up of 1 year. At the end of the 1-year follow-up, 40 of the 74 (54%) patients who underwent successful CV preserved the SR. Mean LAA peak emptying velocity was higher in patients remaining in SR for 1 year than in those with AF relapse (40.3 +/- 15.6 vs 32.2 +/- 12.2 cm/sec cm/sec; p <0.001). On multivariate analysis, only the mean LAA peak emptying velocity > 39 cm/sec and the use of preventive antiarrhythmic drug treatment predicted the continuous preservation of SR during 1 year. CONCLUSION: In patients with nonvalvular AF, measurement of precardioversion LAA flow velocity profile by transesophageal echo cardiography provides valuable information for prediction of both short and long-term success of CV.
