Abstract

Although phasic right coronary artery blood flow in right ventricular hypertension has been studied in animals, reports on human subjects are not available. We observed right coronary artery blood flow before and after operation in a patient with right ventricular hypertension secondary to atrial septal defect using transesophageal Doppler echocardiography. Prior to surgery, blood flow was predominantly diastolic in both right and left coronary arteries. Reversal of right ventricular hypertension after surgery resulted in a change in the pattern of right coronary flow, with doubling of flow during systole.
