Coronary sinus (CS) is a landmark for cardiac intervention. Before catheter ablation of paroxysmal supraventricular tachycardia, coronary sinus is used to obtain recordings from the left atrium and ventricle. Despite asymptomatic, anomalies of coronary sinus may become an obstacle for electrophysiological catheterization. Here, we described a case of successful ablation of paroxysmal supraventr...
