ASYMMETRIC HYPERTROPHIC OBSTRUCTIVE CARDIOMYOPATHY

37-year-old female with a history of hypertrophic cardiomyopathy presented to the ER with pleuritic chest pain
CXR showed cardiomegaly with evidence of left ventricular enlargement and left atrial enlargement.

CTA showed no evidence of PE but confirmed the presence of LAE and LVH with asymmetric septal thickening and relative sparing of the apex.

An echocardiogram confirmed the presence of an obstructive cardiomyopathy with systolic anterior motion of the mitral valve and late systolic mitral regurgitation. The left atrium was enlarged and the right atrium was mildly enlarged. The ejection fraction was normal and estimated to be between 64%. There was a resting gradient across the outflow tract of 40-68 mmHg. LV mass index was 156g/sq m

Image a and b are in systole and show systolic anterior motion of the mitral valve into the LVOT (green arrowhead). In diastole the anterior leaflet is open (d green arrowhead)
Note also the relative thickness of the septal wall (red line) compared to the free wall (white line).

MRI confirmed the findings of the echo showing asymmetric septal hypertrophy, systolic anterior motion of the mitral valve with mitral regurgitation. The LA was 5.2cms, septal wall in diastole was 27.6mms and free wall was 16.8 mms. LV cavity size in diastole was normal. RA and RV were normal. EF was 70% and LV mass was 130g/ sq. m
