[Dynamics of the interrelationships of functional and morphologic parameters of the left and right ventricle in coarctation and decoarctation of the ascending aorta].
The contractile and ultrastructural parameters of the left and right ventricles were studied in rabbits 3 weeks after ascending aortic coarctation by a third of the baseline diameter. In other rabbits, the same parameters were studied 1, 2, 3, and 4 weeks after recovery of the normal aortic lumen following three weeks of its narrowing. It was found that a rapid recovery of the parameters under study did not occur after decoarctation despite the fact that left ventricular overload was abolished. A fortnight after decoarctation there was a profound increase in the contractility of the two ventricles and three weeks there was a significant enhancement of cardiomyocytic mitochondrial function.
