Key result
Upper hemisternotomy for the David procedure achieves 1.6% 30-day mortality without conversion to full sternotomy.
Why the study?
Due to its complexity, the David procedure is not routinely performed via an upper mini hemisternotomy.
Observational (n=62)
No
The David procedure can be safely performed via an upper hemisternotomy in selected patients, with low 30-day mortality and no need for conversion to full sternotomy.

May support upper hemisternotomy David procedure in selected patients; leaves open need for comparative trials.
Background: Due to its complexity, the David procedure is not routinely performed via an upper mini hemisternotomy. We present our results with David procedure performed via an upper hemi-sternotomy. Methods: Between Apr 2011 and Dec 2018, 62 patients (55 males, age 48.5±12.1 years) underwent elective aortic valve sparing root replacement (David procedure) via an upper hemisternotomy. Thirty patients (48.4%) underwent additional leaflet repair. Concomitant procedures were: five (8.1%) proximal aortic arch replacements and two (3%) coronary artery bypass grafting (CABG) to the proximal right coronary artery (RCA). Results: There were no intra-operative conversions to full sternotomy. The aortic cross-clamp and cardiopulmonary bypass (CPB) times were 126.4±28.8 and 191.4±39 min, respectively. Five patients (8.1%) were re-opened (via same access) due to post-operative bleeding. The post-operative ventilation time was 0.6±1.0 days. There was one 30-day mortality (1.6%). Conclusions: In carefully selected patients, the David procedure can be performed safely via an upper hemi-sternotomy. Attention to surgical details, especially hemostasis is even more important when choosing this access to prevent perioperative complications.

Beckmann et al. (2021) conducted an observational in Aortic root disease requiring aortic valve sparing root replacement (n=62). Aortic valve sparing aortic root replacement (David procedure) via an upper hemisternotomy was evaluated on 30-day mortality. Aortic valve sparing root replacement (David procedure) via an upper hemisternotomy was performed with no intra-operative conversions to full sternotomy and a 30-day mortality of 1.6%.
