Surgical feasibility of ascending aorta manipulation after transcatheter aortic valve implantation: a computed tomography theoretical analysis.

ABSTRACT:

Aims

The expansion of TAVI will involve an increase in the frequency of emergent or late cardiac surgery after THV implantation. This study was designed to investigate the anatomical feasibility of surgical cross-clamp and aortotomy after TAVI through a post-TAVI CT-scan assessment.

Methods and results

We retrospectively analysed 117 CTs acquired after TAVI procedures with high stent prostheses in three high-volume centres between October 2008 and May 2017. The mean distance observed between the innominate artery and the top of the transcatheter heart valve was 45±11 mm, being <30 mm in 8/117 (6.8%) patients and <20 mm in none. The mean distance between the sinotubular junction and the first free site for aortotomy was 22±7 mm (>20 mm in 78/117 [66.7%] cases). A total of 56/
