Cardiac catheterization and angiocardiography studies are reported in two patients with syphilitic aortic aneurysms, both of which compromised the pulmonary circulation. In the first instance the right main pulmonary artery was compressed and pulmonary hypertension proximal to the compression resulted. In the second patient the aneurysm ruptured into the pulmonary artery producing an aortic-pul...

An unsuspected metastasis of liposarcoma of the heart was detected on a computed tomographic (CT) examination of the chest. Further CT study with i.v. contrast administration gave excellent delineation of the tumor. Compared with two-dimensional echocardiography and angiocardiography, CT was best at showing the myocardial and intrapericardial extension of the tumor, but did not show movement of...

Nuclear angiocardiography with a gamma camera, a pinhole collimator, and 99mTc pertechnetate was performed on 43 children aged 3 years or less, including 10 neonates. Twenty-six children had congenital heart disease, which was confirmed at cardiac catheterization; the rest had no structural cardiac anomaly. Use of the pinhole collimator allowed magnification of cardiac images, with enhancement ...

Aneurysm of the membranous portion of the interventricular septum is considered to be a rare congenital anomaly, and to date only a few publications have documented ante-mortem diagnoses. Taussig (1960) reviewed the published reports and was able to find 80 cases diagnosed at necropsy. Steinberg (1957), using angiocardiographic studies, reported the first living patient with this defect. Two re...
