Safety of radiofrequency catheter ablation without coronary angiography in aortic cusp ventricular arrhythmias.


BACKGROUND Ventricular arrhythmias (VAs) originating from the aortic root are common. Coronary angiography is typically recommended before catheter ablation to document proximity of the ablation catheter to the coronary ostia. OBJECTIVE To investigate how often catheter ablation in the aortic root could be guided by phased-array intracardiac… (More)
