Abstract

BACKGROUND
Radiofrequecy(RF) catheter ablation is the choice of treatment of refractory supraventricular tachycardia. Althogh catheter ablation is invasive, it is well-known that this procedure is safe. However RF catheter ablation may provoke some adverse conditions. The purpose of this study was to assess functional and morphologic changes shortly after radiofrequency catheter ablation in patients with supraventricular tachycardia by means of two-dimensional echocardiography. METHOD: Echocardiogram underwent 1 day before and within 3 days after RF catheter ablation. Cardiac chamber size, wall thickness, and valve motion in the M-mode were Measured. Left ventricular volume, area, dimension, pericardial effusion and segmental wall motion were measured by means of two-dimensional echocardiography and valve incompetence were also measured with color Doppler echocardiography.
RESULTS
New echocardiographic abnormalities were observed in 4(5.4%) among 73 patients. One mild aortic regurgitation,one increase in severity of tricuspid imcompetence, one increase in severity of mitral regurgitation and one mild pericardial effusion were found.
CONCLUSION
We concluded that echocardiographic changes after radiofrequency ablation are rate and of minor significance.
