EFFECTS OF ACUTE ISCHEMIC MITRAL REGURGITATION ON THREE DIMENSIONAL MITRAL LEAFLET EDGE GEOMETRY

摘要

Background:Improved quantitative understanding of in-vivo leaflet geometry in ischemic mitral regurgitation (IMR) is needed to improve reparative techniques, yet few data are available due to current imaging limitations. Using marker technology we tested the hypotheses that IMR: (1) Occurs chiefly during early-systole; (2) Affects primarily the valve region contiguous with the myocardial ischemic insu and, (3) Results in systolic leaflet edge restriction.
