Premature ventricular complex (PVC) usually follows a benign course and shows good response to medical therapy. However, high burden of PVC deteriorates cardiac function and is often associated with progression into dilated cardiomyopathy (DCMP). We report a case of a young patient who recovered from DCMP after PVC ablation. The patient complained of palpitations and dyspnea on exertion. Holter examination revealed an isolated PVC burden of 29%. Despite intensive medical therapy for more than a year, symptoms aggravated and PVC burden was not diminished on follow-up Holter examination. Furthermore, the echocardiogram revealed deteriorated systolic function as well as left ventricular enlargement, indicating progression into DCMP. Surface electrocardiogram indicated PVC origin in the left ventricular outflow tract. Detailed mapping at the right ventricle and left ventricle outflow tract with the aid of 3-dimensional mapping system, demonstrated PVC origin from the left ventricular outflow tract area, between the right and left coronary cusps. Radiofrequency ablation successfully abolished all ventricular premature beats. Follow-up Holter examination revealed no PVC, and the echocardiogram showed recovery to normal systolic function and chamber size. In conclusion, ablation of PVC should be considered when it does not respond to medical therapy and is associated with deterioration of cardiac function.
