Outcomes From the EXPLANT-TAVR Registry: Time to Change TAVR Informed Consent?

A Case of Ascending Aortic Replacement and Aortic Valve Replacement in a Patient with Giant Pseudoaneurysm of the Ascending Aorta due to Prosthetic Valve Endocarditis after Transcatheter Aortic Valve Replacement Using Evolut PRO

An 82-year-old man who underwent transcatheter aortic valve replacement (TAVR) using a 34-mm Evolut PRO (Medtronic, Minneapolis, MN, USA) for severe aortic stenosis 21 months previously presented with fever. Transesophageal echocardiography showed thickening of the valve leaflets of the transcatheter heart valve and movable structures such as verrucae on the upper edge of the Evolut PRO stent. Contrast-enhanced cardiac computed tomography showed a 72-mm saccular pseudoaneurysm on the dorsal aspect of the ascending aorta at the superior border of the Evolut PRO stent. Because of a suspected infected aortic aneurysm caused by prosthetic valve endocarditis (PVE), we performed aortic valve replacement using 23 mm Avalus (Medtronic, Minneapolis, MN, USA) and ascending aortic replacement using 26 mm Gelweave (Vascutek Terumo Inc, Scotland, UK). The postoperative course was uneventful. This report highlights that patients with PVE after TAVR may develop pseudoaneurysms of the ascending aorta.
