Pathophysiological and clinical implications of high intramural coronary blood flow velocity in aortic stenosis

We sought to recognize the blood flow velocity (BFV) through the left anterior descending (LAD) coronary artery and its small intramyocardial (IM) branches by transthoracic Doppler-echocardiography in patients with aortic stenosis (AS). Sixty-two patients, aged 74.0 ± 9.6 years, 37 women, with preserved left ventricular (LV) function, apparently free of active ischemic disease, were enrolled and classified into 3 groups according to the mean...
