Key result
Contrast enhanced cross sectional echocardiography successfully assessed the importance of collateral blood flow in the myocardium of two patients with anteroseptal myocardial infarction.
Why the study?
Can contrast enhanced cross sectional echocardiography assess collateral blood flow in patients with prior myocardial infarction?

Can contrast enhanced cross sectional echocardiography assess collateral blood flow in patients with prior myocardial infarction?
Contrast enhanced cross sectional echocardiography is a feasible method for assessing the importance of collateral blood flow in the myocardium.

May facilitate real-time collateral perfusion assessment post-MI; leaves open validation against angiography in larger studies.
Contrast enhanced cross sectional echocardiography is a new method for the real-time evaluation of regional myocardial perfusion. Two patients with a history of anteroseptal myocardial infarction and echocardiographically detected septal dyskinesia were examined by this new method. The first patient had two severe stenoses of the left anterior descending coronary artery and normal echocontrast opacification of the interventricular septum caused by collaterals from the right coronary artery. The second patient had good patency of left anterior descending coronary artery and no septal opacification. Thus contrast enhanced cross sectional echocardiography can be used to assess the importance of collateral blood flow in the myocardium.

Widimský et al. (1988) conducted a case report in Anteroseptal myocardial infarction and septal dyskinesia (n=2). Contrast enhanced cross sectional echocardiography was evaluated on Evaluation of regional myocardial perfusion and collateral blood flow. Contrast enhanced cross sectional echocardiography successfully assessed the importance of collateral blood flow in the myocardium of two patients with anteroseptal myocardial infarction.
