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.

D006973 Hypertension Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more.

D006344 Heart Septal Defects, Atrial Developmental abnormalities in any portion of the ATRIAL SEPTUM resulting in abnormal communications between the two upper chambers of the heart. Classification of atrial septal defects is based on location of the communication and types of incomplete fusion of atrial septa with the ENDOCARDIAL CUSHIONS in the fetal heart. They include ostium primum, ostium secundum, sinus venosus, and coronary sinus defects.
