Left ventricular filling in differentiating restrictive amyloid cardiomyopathy and constrictive pericarditis

摘要: Abstract Left ventricular filling was evaluated with use of digitized left ventriculograms in patients (1) restrictive amyloid cardiomyopathy, (2) constrictive pericarditis, and (3) a normal heart. Restrictive cardiomyopathy (four patients) established by right heart hemodynamic studies postmortem examination; all four had cardiac amyloidosis. Constrictive pericarditis (seven characteristic catheterizatlon data pericardial disease at operation; calcific three noncalcific anatomic changes.
