Key result
Direct Dacron bypass graft puncture with MANTA closure enables successful TAVI in severe peripheral disease.
Why the study?
Complex vascular anatomies due to peripheral artery disease or previous aorto-femoral bypass surgery pose challenges for TAVI access and closure.
Case Report (n=1)
Demonstrates the feasibility of utilizing a MANTA vascular closure device following TAVI performed via direct puncture of a Dacron aorto-femoral bypass graft in patients with complex vascular anatomy.
Direct graft puncture may enable TAVI in complex bypass anatomy; hypothesis-generating and should not yet change practice.
Transfemoral Aortic Valve Implantation (TAVI) has emerged as a standard treatment option for patients with symptomatic severe aortic stenosis. However, complex vascular anatomies due to peripheral artery disease or previous aorto-femoral bypass surgery can pose significant challenges for both access and subsequent closure of the access site. In this report, we describe a case of TAVI performed via direct puncture of an aorto-femoral Dacron bypass graft and demonstrate the feasibility of vascular closure using a MANTA (Teleflex) device, an anchored collagen-plug vascular closure device.

Shakya et al. (2026) conducted a case report in Severe aortic stenosis and severe peripheral vascular disease (n=1). TAVI via direct puncture of an aorto-femoral Dacron bypass graft and MANTA closure was evaluated on Feasibility of vascular closure. TAVI performed via direct puncture of an aorto-femoral Dacron bypass graft with subsequent MANTA vascular closure is feasible in a patient with severe peripheral vascular disease.
