Phasic coronary flow velocity in the left and right coronary artery was recorded in a patient with microvascular angina. Coronary flow velocity during anginal attack was characterized by diminished systolic forward velocity, the appearance of systolic flow reversal, increase in diastolic flow velocity and its rapid deceleration. It was also accompanied with abnormal coronary flow reserve. These findings completely recovered at follow‐up examination. A subgroup of patients with microvascular angina may show unique and reversible coronary flow abnormalities during chest pain. Cathet. Cardiovasc. Intervent. 50:63–67, 2000. © 2000 Wiley‐Liss, Inc.
