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.

摘要

虽然已经在动物身上研究了右心室高压时的右冠状动脉阶段性血流情况，但尚无关于人类受试者的报道。我们使用经食管多普勒超声心动图观察了一名因房间隔缺损继发右心室高压患者手术前后的右冠状动脉血流情况。手术前，右冠状动脉和左冠状动脉的血流主要在舒张期。手术后右心室高压的逆转导致右冠状动脉血流模式发生改变，收缩期血流增加了一倍。
