Mitral Valve Area, AP/commissural dimensions, and MAC
The mean MVA was 4.7 +/- 1.19cm2 on TEE vs 4.9 +/- 1.63 on MDCT (p= 0.73). Both AP diameter (29.7 +/- 5.5mm vs 31 +/- 5.07mm, P=0.4) and commissural diameter (37.01 +/- 6.5mm vs 38.77 +/- 4.91mm, P= 0.3) were similar between TEE and MDCT. Degree of MAC was also similar in 91% with MAC underestimated on TEE in 2 patients (Table II).
