Unlabelled:
A 53-year old woman without a previous history of cardiac disease was successfully resuscitated from ventricular fibrillation. Despite a normal two dimensional echocardiogram, tissue Doppler analysis of left ventricular long-axis contraction revealed marked postsystolic contractions in the territory of the left coronary artery suggesting ischemia as the underlying pathogenetic mechanism. This was confirmed by coronary angiography which revealed a high-grade ostial stenosis of the left main stem. After coronary artery bypass surgery, the tissue Doppler findings normalized.
Conclusion:
Assessment of regional long axis function by tissue Doppler echocardiography may yield important additional findings even if two-dimensional echocardiography is apparently normal.
