| Popis: | The cineangiocardiograms and coronary angiograms of two cases of amyloidosis of the heart were compared to six cases of constrictive pericarditis. Three angiographic differentiating points were seen: (1) right ventricular free wall motion showed diastolic restriction in both disorders, whereas the crista supraventricularis, which moved normally in constrictive pericarditis, demonstrated restriction in amyloidosis; (2) ventricles in cases of constrictive pericarditis showed subtle further expansion during atrial systole after initial rapid filling (atrial kick), while in both cases of amyloidosis there was no motion during atrial systole; (3) pericardial thickening in constrictive pericarditis was demonstrated by failure of the distal coronary arteries to reach the surface of the cardiac image. In amyloidosis, the distal coronary arteries normally reached the periphery of the image. All three signs may be useful in differentiation, but the first is the easiest to evaluate. The right anterior oblique or posteroanterior view is the recommended projection. |
