Key result
CT-guided aortic valve neocuspidization with CABG achieves a ~12-mmHg peak transvalvular gradient with trace insufficiency.
Why the study?
The original Ozaki technique requires sizing and trimming neovalve cusps during aortic cross-clamp, which prolongs ischaemic time compared with standard aortic valve replacement.

Preoperative CT planning enables pre-bypass leaflet sizing in Ozaki-CABG; leaves open whether ischemic time or durability improves versus standard technique.
The original Ozaki technique involves sizing and trimming the neovalve cusps during cross-clamp. It leads to prolongation of the ischaemic time, as compared to standard aortic valve replacement. We use preoperative computed tomography scanning of the patient's aortic root to develop personalized templates for each leaflet. With this method, autopericardial implants are prepared before the initiation of the bypass. It permits maximally adopting the procedure to the patient's individual anatomy and to shorten the cross-clamp time. We present a case of a computed tomography-guided aortic valve neocuspidization and concomitant coronary artery bypass grafting with excellent short-term results. We discuss the feasibility and technical details of the novel technique.

Todurov et al. (2022) conducted a case report in Severe bicuspid aortic stenosis and three-vessel coronary artery disease (n=1). Computed tomography-guided aortic valve neocuspidization (AVNeo) with concomitant coronary artery bypass grafting (CABG) was evaluated on Postoperative transvalvular peak/mean pressure gradient and valve competence at 1 month. CT-guided aortic valve neocuspidization with concomitant CABG achieved a 108-min cross-clamp time and a 12/7 mmHg transvalvular gradient with trace insufficiency at 1 month.
