Key result
In vivo evaluation of the 25-mm St. Jude aortic valve within 48 hours post-surgery demonstrated a low mean gradient of 3.3 mmHg and an effective valve area comparable to the geometric area.
Why the study?
What are the hemodynamic flow characteristics of the St. Jude prosthetic aortic valve in vitro and in vivo?
What are the hemodynamic flow characteristics of the St. Jude prosthetic aortic valve in vitro and in vivo?
The St. Jude prosthetic aortic valve provides excellent hemodynamic performance with low gradients, low turbulence, and optimal effective valve area.
No takes yet. Share an insight, caveat, or question.
Supports early hemodynamic assessment after mechanical aortic valve replacement; leaves open durability and outcome questions for prospective evaluation.
Yoganathan et al. (1982) studied Aortic valve replacement (n=6). St. Jude cardiac prosthetic aortic valve was evaluated on Valve gradient and effective valve area. In vivo evaluation of the 25-mm St. Jude aortic valve within 48 hours post-surgery demonstrated a low mean gradient of 3.3 mmHg and an effective valve area comparable to the geometric area.
