Summary
Simultaneous abdominal aortic aneurysm (AAA) repair and transcatheter aortic valve replacement (TAVR) is an effective option when transfemoral TAVR is challenging. This combined approach avoids higher-risk alternative TAVR methods.
Area of Science:
- Cardiovascular Surgery
- Interventional Cardiology
Background:
- Transcatheter aortic valve replacement (TAVR) is primarily performed via the transfemoral (TF) approach.
- Alternative transapical (TA) or transaortic (TAo) TAVR approaches have higher complication rates.
- Severe aortic stenosis (AS) can coexist with abdominal aortic aneurysm (AAA), posing complex treatment challenges.
Observation:
- A simultaneous approach combining abdominal aortic aneurysm (AAA) replacement and TAVR was performed due to difficulties with standard stent graft implantation and TF-TAVR.
- TAVR was facilitated using artificial vascular grafts during the AAA repair procedure.
Findings:
- Simultaneous AAA replacement and TAVR using a Y-graft prosthesis is a viable strategy when TF-TAVR is anatomically difficult.
- This combined procedure effectively manages both severe aortic stenosis (AS) and abdominal aortic aneurysm (AAA).
Implications:
- This approach avoids the need for higher-risk TA or TAo TAVR procedures.
- It allows for postoperative management without the complicating factor of severe aortic stenosis (AS).
- Simultaneous surgical AAA repair and TAVR offers an effective treatment option for complex cases, potentially becoming more relevant with evolving TAVR indications.
