Comparison of relation of systolic flow of the right coronary artery to pulmonary artery pressure in patients with and without pulmonary hypertension.
Systolic flow velocity is relatively predominant over diastolic velocity in the proximal right coronary artery and right ventricular branch in patients with normal systolic pulmonary artery pressure. The amount of systolic flow velocity reduction in the proximal right coronary artery and right ventricular branch is inversely related to the level of pulmonary hypertension.
