Why the study?
How do different annuloplasty rings affect mitral annular strains in a normal beating ovine heart?
How do different annuloplasty rings affect mitral annular strains in a normal beating ovine heart?
In a healthy ovine model, annuloplasty rings induce compressive strains predominantly in the lateral annular region, with strain profiles depending on specific ring design rather than just the degree of septal-lateral downsizing.
No takes yet. Share an insight, caveat, or question.
Ring-specific strain patterns in ovine annuloplasty leave open optimal human ring selection; hypothesis-generating pending clinical validation.
Bothe et al. (2012) studied this question.
