Surgery is an effective treatment for left ventricular aneurysm (LVA). However, sudden cardiac death caused by malignant ventricular arrhythmia (VA) occurring between 30 days and 5 years postoperation accounts for 29.6% and 36.8% of the total deaths recorded, respectively.1 Radiofrequency ablation is commonly used for treating VA.2 We report a patient with ventricular tachycardia who underwent LVA repair and bipolar radiofrequency ablation with good preliminary efficacy.
A 53-year-old man with a history of diabetes mellitus and myocardial infarction was referred for cardiac surgery for unstable angina. His cardiac function was New York Heart Association grade IV. Coronary angiography showed triple-vessel lesions. Echocardiography revealed paradoxical cardiac movements of the left ventricle in the systolic phase, a left ventricular ejection fraction of 0.32, and a left ventricular end-diastolic diameter of 60 mm. The LVA was located in the apex of the left ventricle without mural thrombosis. Electrocardiography and Holter monitoring confirmed the presence of frequent multifocal VA (67540/24 hours) and paroxysmal ventricular tachycardia. An electrophysiology study using the CARTO system . . . [Full Text of this Article]
