Influences of aortic pressure gradient and ventricular septal thickness with systolic coronary flow in aortic valve stenosis.
This study evaluates flow patterns of the left anterior descending and circumflex coronary arteries by multiplane transesophageal echocardiography in 25 patients with aortic valve stenosis, and assesses the relation between coronary flow characteristics and anatomic and hemodynamic parameters.
