Does radiofrequency ablation improve LV size and function in patients with LV dysfunction resulting from frequent unifocal ventricular ectopics?
Frequent ventricular ectopy should be considered as a potentially remediable cause of LV dysfunction, as radiofrequency ablation can lead to normalization of LV size and function.
A case is presented, in which asymptomatic but persistent right ventricular outflow tract (RVOT) ectopics resulted in left ventricular (LV) dilatation and systolic dysfunction. The patient underwent extensive investigation with no other cause for the cardiomyopathy being found. Successful ablation of the RVOT ectopic focus resulted in normalization of LV size and function. This case suggests that frequent ventricular ectopy should be considered as a potentially remediable cause of LV dysfunction.
