Characteristic of morphometric parameters of intramural coronary arteries and myocardial bridges in the adult human heart

[Morphology]
Evgeniya Germanovna Dmitrieva;

The characteristics of morphometric parameters of the myocardial bridges and the intramural sections of the branches of the coronary arteries located under them were studied by histological method on 60 preparations of the heart of people of the second period of mature and elderly age who died from causes unrelated to the pathology of the heart and its vessels. Ranges of their individual variability have been established. Correlations between the thickness of the myocardial bridges, the width of the perivascular space and the size of the outer diameter of the intramural artery were revealed. A new definition of myocardial bridges is proposed. The obtained data can be used to optimize surgical tactics during open and endovascular interventions on coronary arteries in the presence of myocardial bridges in patients with coronary heart disease.
