The TATEGIRI technique: adaptation of a longitudinal aortotomy for totally endoscopic aortic valve replacement.

ABSTRACT:

Background

Endoscopic aortic valve replacement (TE‑AVR) is hindered by restricted visualization and instrument maneuverability. We describe TATEGIRI (Japanese: "vertical cut"), a longitudinal aortotomy adapted for the endoscopic setting.

Methods

Between August 2023 and August 2024, 28 consecutive patients (23 sternotomies and five MICS) underwent AVR using the TATEGIRIapproach. Perioperative variables, procedural feasibility, and early outcomes were prospectively assessed.

Results

The median cardiopulmonary bypass time was 142 min and the aortic cross-clamp time was 97 min. Valve size distribution was 19 mm in one patient (3.6%), 23 mm in eight (28.6%), 25 mm in seven (25%), 27 mm in five (17.9%), and 29 mm in one (3.6%). The mean prosthesis diameter was 24.5 ± 3.1 mm
