Ventricular coupling in constrictive pericarditis.
Because of the close anatomic association, the volume or pressure in one ventricle can directly influence the volume and pressure in the other ventricle. Disease states that reduce pericardial compliance should accentuate this coupling between the ventricles. We examined this hypothesis in six dogs. Constrictive pericarditis was induced by injecting an irritant mixture into the pericardial cavi...
متن کاملConstrictive pericarditis.
A study has been made of 62 patients with constrictive pericarditis. There was considerable variation from the classical description of the disease. It is hoped that the findings may be of use, because both diagnosis and treatment can sometimes cause perplexity. The atiology and mode of onset of constrictive pericarditis will be considered first, since ,these have important effects on the final...
متن کاملConstrictive Pericarditis
T HE essential pathology of constrictive pericarditis is the partial replacement of the epicardium and superficial myocardial layers by inelastic fibrous tissue. This interferes with diastolic filling of the ventricles and is recorded during right ventricular catheterization as a high end-diastolic plateau. In addition, the encasing and infiltrating lesion interferes with contractility and ther...
متن کاملConstrictive pericarditis
Constrictive pericarditis — Constrictive pericarditis is the result of scarring and consequent loss of the normal elasticity of the pericardial sac. Pericardial constriction is typically chronic, but variants include subacute, transient, and occult constriction. Pathologically, this results in chronic inflammation and, frequently, calcification. Grossly, the pericardium is considerably thicker ...
متن کاملConstrictive pericarditis.
The hemodynamic findings in five patients are presented in order to demonstrate the variability in the clinical and physiologic patterns that may be encountered in restrictive disease of the pericardium. The mechanical effects of pericardial encasement previously described were confirmed. Furthermore, it was found that myocardial insufficiency and hypervolemia were not only important causative ...
