Resistant Ventricular Tachycardia due to Idiopathic Left Ventricular Aneurysm: Successful Treatment with Surgery.

Left ventricular aneurysms (LVAs) are characterized by a wide connection to the left ventricle and paradoxical systolic motions. Although patients with LVAs are usually asymptomatic, some may present with arrhythmias, heart failure, and even cardiac arrest. In this case report, we describe a 62-year-old male patient who presented to our emergency service with complaints of palpitation and shortness of breath of 2 hours' duration. His blood pressure was 84/56 mm Hg, and he was in a confused state. An electrocardiogram revealed ventricular tachycardia (VT) with right bundle branch block and a ventricular rate of 188 bpm. The patient's hemodynamic instability necessitated a direct current cardioversion, which restored the sinus rhythm. During the in-hospital course, he had numerous recurrent VT episodes despite treatment with intravenous amiodarone and magnesium sulfate as well as radiofrequency ablation. Upon consensus with a cardiovascular surgeon's team, urgent surgery was performed due to the resistant VT episodes. The patient's clinical course was uneventful, and he was discharged on the 11th postoperative day. We have been following up the patient for almost 1 year, during which he has not experienced palpitations or associated symptoms. Our case indicates that surgery may be a preferable treatment option for patients with heart failure and resistant VT related to LVAs.
