Successful Catheter Ablation for Incessant Ventricular Tachycardia in a Patient With Hypertrophic Cardiomyopathy

概要

• 論文の詳細を見る

• A 35-year-old man was referred to Nihon University Hospital because of repetitive ventricular tachycardia (VT) at 180-200beats/min. QRS morphology of the VT was right bundle branch block with a northwest axis. Trans-thoracic echocardiography showed hypertrophic cardiomyopathy. Coronary angiography was normal and left ventriculography showed neither obstruction in the left ventricle (LV) nor any pressure gradients within the LV or between the LV and aorta. Hemodynamic deterioration occurred during VT. Intracardiac mapping showed that the VT originated from the posteroseptal portion of the LV near the apex and Purkinje potentials that preceded the onset of the QRS complex by 58-70 ms were documented. Radiofrequency ablation at these sites terminated the VT, which has not recurred for 25 months.
