Regional mitral valve tenting area (MVTa [tenting distribution]) plotted as a function of intercommissural (IC) position, expressed as a percentage of the distance traveled from the anterior commissure (AC). The positions of the AC and posterior commissure (PC) are, respectively, 0% and 100%. (A) Mean data (with SEM) for the normal cohort and ischemic mitral regurgitation (IMR) cohorts with either inferior or anterior infarcts. Note the shifting of the maximum tenting area toward PC with anterior infarct location. (B–E) Data for selected individual IMR patients are displayed. Note the variability in the extent and location of leaflet tenting. (Black line = normal; dark gray line = inferior; light gray line = anterior.)
