Changes in heart size have been studied by means of intra ventricular gages, serial roentgenography and cinefluoiographic angiocardiography. Evidence is presented that the area of the cardiac silhouette and the area and diameter of the left ventricle all diminish in response to thoracotomy and during recovery return toward the pre-operative dimensions. Since fundamental concepts of cardiac func...

Tricuspid atresia is one of the less common forms of congenital heart disease. The results of palliative surgery in 72 children are presented. Cardiac catheterization and angiocardiography are essential for precise definition of the anomaly. There is a 20% incidence of obstruction at atrial septal level. Closed atrial septostomy is of value in such cases in infancy. In most there is a reduced p...

A unique case of dissecting aneurysm of the aorta is presented. The dissection spread via a ductus arteriosus to the pulmonary artery andformed a re-entry window at the junction of the main and left pulmonary arteries. Cardiac catheterization and angiocardiography confirmed the presence and approximate site of thefistula. Surgery under cardiopulmonary bypass was effective in closing it. The pat...

Interruption of the aortic arch is a rare and usually lethal cardiac malformation. We report a rare case of a patient with IAA distal to the left subclavian artery associated with double outlet right ventricle, subaortic VSD and patent DA who survived to adulthood. In this patient, the complete diagnosis was made by cardiac catheterization and angiocardiography. We discuss the probable mechanis...

Accurate clinical assessment of the severity of mitral regurgitation is often difficult, and left ventricular cine-angiocardiography is probably the most commonly used method of estimating it. It is therefore important to try to determine the accuracy of this method and to identify as far as possible any causes of error. We have attempted to do this in a series of 137 patients submitted to oper...

A computerized fluoroscopic apparatus developed by members of the University of Wisconsin Medical Physics Section was used for 12 months to perform intravenous video arteriography. In previous papers, the apparatus was described and its use was illustrated for performing time subtraction intravenous video arteriography of the extracranial carotid arteries, the arteries of the abdomen and extrem...

A case, the sixth, ofdouble outlet left ventricle is reported, the diagnosis being made by cardiac catheterization and angiocardiography. Though the existence of such a malformation has been questioned on embryologicalgrounds, double outlet left ventricle must now be regarded as a recognized cardiac anomaly. The embryological significance of this case is discussed and it is suggested that the m...

Two cases of primary malignant cardiac neoplasms are presented. The first, an angiosarcoma of the right atrium, developed in a 44-year-old housewife, who survived 23 days from the time of presentation; diagnosis was made at necropsy. The second, an embryonal rhabdomyosarcoma of the right ventricle, developed in a 17-year-old student; diagnosis was made by angiocardiography. He underwent surgery...

A patient who had had trauma to the right shoulder and upper chest complained of a right supraclavicular mass. Examination revealed a cystic tumor made larger by performance of the Valsalva maneuver. Angiocardiography demonstrated that there was partial stenosis of the terminal end of the right innominate vein. This and the Valsalva manenvnr were responsible for the filling of a right persisten...
