2. Fig. 1
Miniature marker array used. Markers were sutured to the mid-anterior anulus (1), left fibrous trigone (2), anterior commissure (3), left posterior anulus (4), mid-posterior anulus (5), right posterior anulus (6), posterior commissure (7), and right fibrous trigone (8). Markers were also sutured to the midline of the anterior mitral leaflet (markers 9, 10, 11, and 12 to the free edge) and the posterior leaflet (markers 13 to the free edge and 14 ).

A mitral annular plane (bold line) was located by means of the least-squares estimate regression to fit the annular markers. The perpendicular distances (arrows) between the leaflet markers and the mitral annular plane were measured before and during ischemia.
