T. Itoi et al., Abnormal coronary flow reserve in a 13-year-old girl with an absent left circumflex coronary artery, PEDIAT CARD, 22(2), 2001, pp. 165-166
We measured the coronary flow reserve in a 13-year-old girl with the rare a
nomaly of an absent left circumflex coronary artery. Although the coronary
flow volume of the right coronary artery was at the same level as that of t
he left anterior descending coronary artery, the coronary now reserve of th
e patient's right coronary artery was depressed without stenotic lesion, an
d it was less than the level of -2 standard deviation (SD) of the right cor
onary artery preponderance cases.
