Key result
SURD valves linked to improved hemodynamics and less prosthesis mismatch vs stented valves in small annuli.
Why the study?
Aortic valve replacement in patients with severe aortic disease and a small aortic annulus remains clinically challenging and the optimal valve substitute is controversial.
Do sutureless valves perform well in patients with severe aortic disease and a small aortic annulus?
Do sutureless valves perform well in patients with severe aortic disease and a small aortic annulus?
Sutureless valves are highlighted as a potential solution for the clinical challenge of aortic valve replacement in patients with a small aortic annulus.
May support SURD preference in small-annulus AVR; leaves open need for randomized confirmation.
Aortic valve replacement (AVR) in patients with severe aortic disease and a small aortic annulus (SAA) represents a clinical challenge, especially in the setting of aortic stenosis. The optimal valvular substitute for treating these patients remains controversial.

Fiore et al. (2020) conducted an editorial in Severe aortic disease with small aortic annulus (SAA). Sutureless and rapid deployment (SURD) valves vs. Stented valves or TAVI was evaluated. Sutureless and rapid deployment (SURD) aortic prostheses are associated with improved hemodynamic performance and a lower incidence of patient-prosthesis mismatch compared to stented valves in patients with a small aortic annulus.
