The relationship between abnormal echocardiographic septal motion and myocardial perfusion in patients with significant obstruction of the left anterior descending artery.

Abstract

authors have further suggested that AESM implies not only a critical left anterior descending lesion, but that the lesion is proximal to the first septal perforator branch.10 13 Despite the usefulness of coronary angiography in defin- ing the presence of significant obstruction of the major cor- onary arteries, the procedure does not allow visualization of small vessels and therefore does not provide complete information concerning resting myocardial perfusion.
