Right ventricular myocardium in Fallot's tetralogy: a light microscopic, morphometric and ultrastructural study.

Abstract

Peroperative histomorphometric and ultrastructural evaluation of the RV myocardium in Tetralogy of Fallot reflects the effect of haemodynamic stresses on the right ventricular muscle and correlates with clinical cardiac dysfunction. It may be a useful adjunct in determining the time for surgical intervention and in predicting clinical outcome.
