Mitral Valve Coaptation Reserve Index: A Model to Localize Individual Resistance to Mitral Regurgitation Caused by Annular Dilation
Authors' conclusion
Quantification and indexing of mitral coaptation reserve along the closure line are feasible. Indexing and mathematical simulation of progressive annular dilatation consistently showed that indexed coaptation reserve was lowest in the A2-to-P2 region.
Study context
- Population
- Patients with normally functioning mitral valves undergoing cardiac surgery
- Participants
- 25 patients
- Outcome
- Leaflet coaptation (reserve) along the closure line per segment (A1-P1, A2-P2, A3-P3), and the indexed CRI after simulated progressive annular dilation
