[Morphologic consideration of heart failure (author's transl)].
The left ventricle in left heart failure can be elliptical, spherical or funnel shaped. There is no firm correlation between the different shapes and the hemodynamics. Left ventricular failure results in dilatation, deformation and loss of funnel function of the left atrium. In more advanced stages of left ventricular failure the pulmonary veins become coiled, dilated and narrow stepwise instead of the normal harmonic narrowing to the periphery. The pulmonary parenchyma exhibits fibrosis and septal siderosis at that stage. Heart failure cells can be observed frequently. In later stages, when pulmonary arteries and the right ventricle is involved, secondary global heart failure develops. Right ventricular failure may lead to necrosis of liver cells with jaundice and elevated levels of liver specific enzyms. Primary global failure has no hemodynamic consequences on the pulmonary circulation, as long as left and right ventricular failure are of equal severity. If one form prevails, the clinical picture will be that of left or right ventricular failure respectively.
