Coronary Microvascular Spasm as the Underlying Cause of the Angiographic Slow Flow Phenomenon

Coronary Microvascular Spasm as the Underlying Cause of the Angiographic Slow Flow Phenomenon

Slow coronary flow is frequently seen during angiography in patients with angina and unobstructed coronary arteries. However, the pathophysiology of this finding remains largely unclear. We report a case of a 52-year-old woman with slow coronary flow caused by acetylcholine-induced microvascular spa...

Description
Summary:Slow coronary flow is frequently seen during angiography in patients with angina and unobstructed coronary arteries. However, the pathophysiology of this finding remains largely unclear. We report a case of a 52-year-old woman with slow coronary flow caused by acetylcholine-induced microvascular spasm, as confirmed by intracoronary flow measurements. (Level of Difficulty: Beginner.)
