[Determination of pulmonary capillary wedge pressure by the sectoral scanning method].

Eighty-seven cases of acute myocardial infarction were examined by sectoral scanning to assess the contractility of all heart chambers. The data, particularly the occlusion pressure of pulmonary capillaries, were compared with those obtained at catheterization of the right compartments of the heart. Mathematical formulas were derived to enable the identification of patients with increased occlusion pressure and quantify its magnitude on the basis of noninvasive echocardiographic studies.
