Conservative Management of Left Ventricular Pseudoaneurysm After Transfemoral Transcatheter Aortic Valve Implantation.

Left ventricular pseudoaneurysm is a rare complication, most commonly occurring after myocardial infarction or cardiac surgery. It carries a high risk of spontaneous rupture and may lead to ventricular arrhythmias, heart failure, or thromboembolism. Cases of left ventricular pseudoaneurysm following transcatheter aortic valve implantation (TAVI) are extremely rare, with most requiring emergency surgical intervention. We present a case of a patient who developed ventricular arrhythmia following transfemoral TAVI. Approximately one week after the procedure, the patient presented to the emergency department with ventricular tachycardia and was treated with amiodarone. A diagnosis of left ventricular pseudoaneurysm was established; however, the patient refused surgical treatment. Instead, an implantable cardioverter-defibrillator was placed, and the patient was managed with medical follow-up. The six-month follow-up period was uneventful.
