[Left Ventricular Pseudoaneurysm after an Apical Approach Transcatheter Aortic Valve Implantation;Report of a Case].

A 79-years-old woman was diagnosed with severe aortic stenosis and referred to our institution for the purpose of an operation. We decided to perform transfemoral transcatheter aortic valve implantation because of her high frailty due to her age and medication of long-term steroid for chronic rheumatoid arthritis. In the operation, left ventricular perforation occurred by the guide wire and cardiac tamponade was detected. We performed pericardial drainage and controlled bleeding through the 5th intercostal thoracotomy and trasncatheter aortic valve implantation was performed after that. Postoperative computed tomography (CT) demonstrated left ventricular pseudoaneurysm in the apex. We performed re-operation because of the enlargement of pseudoaneurysm. The operation was performed through median sternotomy and the pseudoaneurysm was repaired. The patient was discharged after postoperative CT demonstrated the left ventricular wall repaired.
