Key result
MANTA closure device successfully enables fully percutaneous nonsurgical axillary TAVR.
A collagen-based vascular closure device (MANTA) can be utilized for fully percutaneous axillary arteriotomy closure during TAVR, potentially avoiding the need for open surgical techniques.
Should not change TAVR access practice; leaves open feasibility of percutaneous axillary closure pending prospective data.
Percutaneous aortic valve replacement is performed predominantly via the transfemoral approach. The transaxillary (subclavian) approach may be utilized if an alternative route access is required. Conventional access and closure for this approach necessitates open surgical techniques. We report a nonsurgical fully percutaneous axillary TAVR using a collagen-based vascular closure device.

Palma et al. (2017) studied this question. The MANTA collagen-based vascular closure device was successfully used to perform a fully percutaneous, nonsurgical axillary transcatheter aortic valve replacement.
