ABSTRACT
Objective To summarize the ablation methods,and to provide experience reference for the treatment of pulmonary since cusp(PSC)-derived ventricular arrhythmia(VA)with ablation. Methods A retrospective analysis of the clinical data of 19 patients undergoing catheter ablation for PSC-derived VA in Cardiac Intervention Therapy Center,The Second Xiangya Hospital of Central South University between January 2013 and March 2016 was conducted. Results Among the 19 patients,PSC-derived VA originated from the lower regions of the pulmonary sinuses,generating from the right,left,and anterior sinuses of the PSC were identified in 5,7,and 7 patients,respectively. Twelve patients with PSC-derived VAs originating from the right and anterior sinuses underwent successful reversed U-curve catheter ablation,while the other 7 patients with arrhythmias originating from the left sinus underwent successful ablation with the conventional method(non-reversed U-curve catheter ablation). All the patients were followed-up for 6 to 31 months,and no recurrence of VA or complications were recorded. Conclusions Reversed U-curve catheter ablation is suitable for VA originating from the right and anterior PSCs,while conventional ablation can be used for those originating from the left PSCs.
