Introduction to Alternative TAVI Access

Transcatheter aortic valve implantation (TAVI) remains the primary intervention for severe aortic stenosis in high-risk surgical patients. While the transfemoral (TF) route serves as the clinical standard, some patients require alternative access due to severe peripheral artery disease. A recent case study explored the rare use of transapical TAVI LV aneurysm access in a patient with complex comorbidities. This procedure traditionally carries significant risk, yet successful outcomes are possible with careful planning.

The patient presented with severe bicuspid aortic stenosis and advanced ischemic cardiomyopathy. Furthermore, they suffered from chronic obstructive pulmonary disease (COPD) and significant peripheral vascular disease. Initially, the medical team attempted transfemoral access, but the procedure failed due to vascular challenges. Consequently, they turned to the transapical (TA) approach, despite the presence of a left ventricular (LV) apical aneurysm.

Feasibility of Transapical TAVI LV Aneurysm Access

Surgeons traditionally avoid the TA approach in patients with LV aneurysms. They often fear that the fibrosed, thin myocardial tissue might lead to a rupture or uncontrollable bleeding. However, this pioneering case demonstrates that such risks are manageable. Specifically, the team successfully implanted a 29 mm Edwards Sapien S3 Ultra valve directly through the aneurysm. Postoperative recovery remained stable, and the patient showed only trivial paravalvular regurgitation.

Moreover, this clinical milestone suggests that clinicians should not automatically rule out TA access in the presence of an aneurysm. If no other vascular routes are possible, the TA approach offers a viable solution for life-saving valve replacement. Therefore, the perceived fragility of the aneurysm wall may be overestimated in certain high-risk populations.

Frequently Asked Questions

Why is the transapical route usually avoided in LV aneurysm?

Clinicians often avoid this route because fibrosed myocardial tissue in an aneurysm is perceived as thin and friable. This creates a higher theoretical risk of rupture and surgical bleeding during the procedure.

When should clinicians consider transapical TAVI?

Doctors should consider the transapical approach when standard transfemoral access is impossible. This typically occurs in patients with severe peripheral artery disease, extreme vessel tortuosity, or inadequate vessel diameter.

Is the presence of an LV aneurysm a strict contraindication for TA TAVI?

No, as this case demonstrates, successful valve implantation is possible even with a fibrosed LV aneurysm. While it requires expertise, the presence of an aneurysm should not preclude a patient from receiving TAVI when other routes fail.
