Variant angina associated with isolated myocardial bridging： evaluation using intravascular ultrasound and quantitative coronary angiography

Variant angina, first described by Prinzmetal et a in 1959. is hypothesized to be caused by transient coronary＇ vasospasm at the site of an atherosclerotic plaque and leading to repetitive episodes of transmural myocardial ischemia. Myocardial bridging, a congenital coronary abnormality, is defined...

Description
Summary:Variant angina, first described by Prinzmetal et a in 1959. is hypothesized to be caused by transient coronary＇ vasospasm at the site of an atherosclerotic plaque and leading to repetitive episodes of transmural myocardial ischemia. Myocardial bridging, a congenital coronary abnormality, is defined as a segment of a major epicardial coronary after, running intramurally through the myocardium.2 The association of variant angina and isolated myocardial bridging is very uncommon. A review of the literature reveals only one case report）ndicating a causal relationship between the two diseases.We present an additional case who experienced Prinzmetal variant angina related to isolated myocardial bridging of the left anterior descending coronary artery （LAD）, which was evaluated with intravascular ultrasound and quantitative coronary angiography.
