Selectivity in the study of the cardiovascular system.

The principle of selectivity in the roentgenology of the cardiovascular system is now firmly established. The chambers of the heart and certain vascular beds lend themselves admirably to selective catheter or needle study, without the necessity of perfusing large segments of the cardiovascular bed which are irrelevant to a particular study.A technique of percutaneous transfemoral selective ciné coronary arteriography has been developed and applied to clinical subjects. Nevertheless, selectivity has specific limitations, and the use of the selective versus the nonselective approach must be weighed in each case, with the status of the patient as well as the requirements of the diagnostic investigation taken into account in reaching a decision.

Retrograde brachial aortography; its use in the diagnosis of patent ductus arteriosus and coarctation of the aorta in infancy.

Patent ductus arteriosus and coarctation of the aorta are among the commonest causes of congestive heart failure early in life. When medical therapy fails to control heart failure in these cases, surgical division of the ductus or excision of the coarcted segment can be performed. But the recognition of these anomalies in infancy is more difficult than in childhood or adult life. Retrograde thoracic aortography is a technique which permits positive identification. In the presence of patent ductus arteriosus, opacification of the pulmonary arteries from the descending aorta will be clearly shown; if coarctation is present, its position, severity, and the length of the involved segment can usually be demonstrated. Properly employed, retrograde brachial aortography is a relatively safe and effective diagnostic procedure.
