Anatomy of the crista supraventricularis: Its importance for understanding right ventricular function, right ventricular infarction and related conditions

摘要: During careful studies of the human cardiac conduction sy stem anatomy crista supraventricularis is an inescapable concomitant demonstration. For purpose this report observations from about 1,000 hearts were combined with special additional 75 (50 adults, 25 infants), 30 dogs and 5 chickens. The similar in canine hearts. Avian differ mammal that they contain only a muscular right atrioventricular valve which replaces supraventricularis. In addition to dividing inflow outflow pathways ventricle, crucially located join interventricular septum left ventricle much ventricular free wall, thereby playing important role emptying closing tricuspid valve. On basis these observations, function examined relative systole, infarction, various electrophysiologic problems, performance surgery new questions imaging.
