Usefulness of myocardial contrast echocardiography derived coronary flow reserve to accurately determine severity of left anterior descending coronary artery stenosis.
Thirty-five patients underwent quantitative low-power myocardial contrast echocardiography to evaluate the severity of left anterior descending coronary artery stenosis. Coronary flow reserve and myocardial blood flow were able to accurately differentiate among angiographically derived grades of coronary stenosis.
