Key result
Small (19 mm) bileaflet and pericardial aortic valve prostheses showed no significant differences in resting hemodynamics, with 46% of bioprostheses showing non-significant central regurgitation.
Why the study?
Do small (19 mm) bileaflet aortic valve prostheses differ from pericardial bioprostheses in resting hemodynamics among patients with small aortic roots?
Observational (n=43)
Do small (19 mm) bileaflet aortic valve prostheses differ from pericardial bioprostheses in resting hemodynamics among patients with small aortic roots?
Both 19 mm bileaflet and pericardial prostheses demonstrate satisfactory resting hemodynamics and are suitable for implantation in small aortic roots.
No takes yet. Share an insight, caveat, or question.
Comparable resting hemodynamics favor neither prosthesis in small roots; leaves open durability and exercise data.
González‐Juanatey et al. (1995) conducted an observational in Aortic valve replacement with small aortic root (n=43). 19 mm bileaflet aortic valve prostheses vs. 19 mm pericardial aortic valve prostheses was evaluated on Peak or mean transvalvular pressure drop and effective valve area. Small (19 mm) bileaflet and pericardial aortic valve prostheses showed no significant differences in resting hemodynamics, with 46% of bioprostheses showing non-significant central regurgitation.
