title: Pathomorphology and pathogenic role of myocardial bridges in sudden cardiac death.
abstract: Pathognomonic incidence of myocardial bridges during obstructive hypertrophic cardiomyopathy, hypertension, and ischemic heart disease was established. Myocardial bridges were predominantly found in the median segments of major coronary arteries with prevailence of bridge-like obstructions in the anterior interventricular branch of the left coronary artery. Typical changes in cardiac angioarchitectonics indicating pronounced inadequacy of coronary blood flow were determined depending on the segmentary directionality of bridge obstruction. The data attest to pronounced pathogenetic role of myocardial bridges in sudden cardiac death.
