Objective:
We present an older male with severe aortic regurgitation scheduled for transcatheter aortic valve replacement (TAVR). Preoperative imaging identified a giant eccentric abdominal aortic aneurysm at high risk of rupture. This risk was mitigated by a single-stage combined procedure of TAVR and endovascular aneurysm repair.
Key Steps:
Two 8-F sheaths were respectively inserted into the bilateral femoral arteries. We then sequentially dilated the right femoral artery access using 14-F, 18-F, and 20-F introducer sheaths. The self-expanding stent system Endurant II was inserted and released. Coronary angiography assessed the degree of coronary artery stenosis. A 20-F sheath was inserted into the right femoral artery, and then we deployed the Evolut Pro + prosthetic valve.
Potential Pitfalls:
Potential pitfalls include the following: paravalvular leakage, valve displacement or detachment, and rupture of aneurysms.
Take-Home Message:
For surgical high-risk patients with concurrent abdominal aortic aneurysm and severe aortic valve disease, the simultaneous implementation of TAVR and endovascular aneurysm repair may represent a viable therapeutic option.
