TLDR
A patient with an anomalous intramyocardial course of the LAD coronary artery, causing angina pectoris, is described and surgical correction of the anomaly may give symptomatic improvement and improved exercise tolerance.Abstract:
A patient with an anomalous intramyocardial course of the LAD coronary artery, causing angina pectoris, is described. The patient had symptomatic relief after an aortocoronary artery bypass operation. Intramural coronary arteries may be clinically significant. In cases where medical management does not provide relief, surgical correction of the anomaly may give symptomatic improvement and improved exercise tolerance.read more

Myocardial bridges: A review
TL;DR: Only during the last few years, since the first angiographic description of myocardial bridges in vivo by Portsmann et al.
Journal ArticleDOI
Myocardial bridges: morphological and functional aspects.
TL;DR: The superficial type of myocardial bridge does not seem to constrict the artery during systole but the deep muscle bridges, by virtue of their relation with the left anterior descending coronary artery, could twist the vessel and thus compromise its diastolic flow and thus result in ischaemia.
Journal ArticleDOI
The effects of a myocardial bridge on coronary atherosclerosis and ischaemia.
TL;DR: Considering the occurrence of myocardial infarction in cases of proximal MB together with previous reports on relationships between MB and coronary ischaemia, it appears that anatomical characteristics such as the location, length, and thickness of the MB have a bearing on the effects of this abnormality.

Isolated myocardial bridges with angiographic milking of the left anterior descending coronary artery: A long-term follow-up study
Yves Juillière,Véronique Berder,C. Suty-Selton,Philippe Buffet,Nicolas Danchin,Francois Cherrie +5 more
TL;DR: The long-term prognosis of isolated myocardial bridges of the left anterior descending coronary artery is good and is independent of the severity of systolic narrowing of internal lumen diameter.
Journal ArticleDOI
Intramural left anterior descending coronary artery: Significance of the depth of the muscular tunnel
TL;DR: The myocardial changes in group 1 heart and their absence in group 2 hearts suggest that the deep, intramural LADA of the group 1 hearts is abnormal rather than a simple anatomic variant of normal.
