Summary
The authors report 12 cases of myocardial bridges over the anterior interventricular artery discovered surgically. In 5 the compressive myocardial bridges were limited; in 7 the intramyocardial course of the anterior ventricular artery was discovered at operation. Comparison of the operative appearances with the angiographic findings affords a basis for anatomico-radiologic correlation. The authors stress the difference in frequency and significance between the compressive myocardial bridge (an indication for surgery) and the intramyocardial anterior interventricular artery discovered by chance during a procedure for coronary revascularization indicated for stenosing atherosclerotic lesions.
Résumé
Les auteurs rapportent 12 cas de ponts myocardiques sur l'artère interventriculaire antérieure, de découverte chirurgicale: 5 ponts myocardiques compressifs limités, 7 artères interventriculaires antérieures de trajet intramyocardique découvert en peropératoire. L'aspect retrouvé en per-opératoire est comparé aux constatations angiographiques permettant d établir une corrélation anatomo-radiologique. Les autres insistent sur la différence de fréquence et de signification existant entre pont myocardique compressif (d'indication chirurgicale) et artère interventriculaire antérieure intramyocardique (de découverte fortuite lors d'un geste de revascularisation coronarienne indiqué pour des lésions athéroscléreuses sténosantes).
