MCQ : CT-14
Pre Valve in mitral annulus calcification (MAC) assessment in a patient with severe mitral stenosis and previous TAVI:
A and B: mitral annulus measurement
C: simulation of prothese implantation
CT Predictors of LVOT obstruction in Valve in MAC procedure are:
A – aortomitral angle < 110° and LVOT area < 2 cm2
B – aortomitral angle > 110° and LVOT area > 2 cm2
C – aortomitral angle < 110° and LVOT area > 2 cm2
D – aortomitral angle > 110° and LVOT area < 2 cm2
Correct Answer is A : aortomitral angle < 110° and LVOT area < 2 cm2
TEE assessment after valve in MAC, transgastric view, shows normal prosthetic valve function, no regurgitation.
