Key result
The use of sutureless aortic valves significantly reduced cross-clamp time (30.1 vs 50.3 minutes) and cardiopulmonary bypass time compared to conventional biological valves in geriatric patients with small aortic roots.

Sutureless aortic valves significantly reduce cross-clamp and cardiopulmonary bypass times compared to conventional valves in geriatric patients with small aortic roots, facilitating minimally invasive approaches without compromising mortality.
Shrestha et al. (2013) conducted a cohort in Aortic valve stenosis with small aortic root (n=120). Sutureless aortic valve (Sorin Perceval S) vs. Conventional stented biological valves was evaluated on Cross-clamp time (minutes) (p=<0.001). The use of sutureless aortic valves significantly reduced cross-clamp time (30.1 vs 50.3 minutes) and cardiopulmonary bypass time compared to conventional biological valves in geriatric patients with small aortic roots.
