Rapid biplane angiocardiography in the tetralogy of Fallot

Functional Diagnosis of Patent Ductus Arteriosus Studied by Cineangiocardiography in Fifty-three Cases

The hemodynamic alterations revealed by cineangiocardiography in 53 cases of patent ductus arteriosus made possible the correct angiocardiographic diagnosis in 90 per cent of the cases. The most constant functional sign is "blanching of the pulmonary artery," which is seen during diastole and consists of a decrease in density of the pulmonary artery and its branches. This phenomenon has been analyzed by projecting the cineangiocardiograms frame by frame and measuring angiographic density and diameter at the same points of the pulmonary artery. The curves obtained were correlated with each other and plotted against time. The findings were correlated with clinical, surgical, and pathologic information. The hemodynamics of the shunt in patent ductus arteriosus are discussed and a theoretical explanation is offered.

Atypical tetralogy of Fallot: a noncyanotic form with increased lung vascularity; report of four cases

Only recently has the association of pulmonic stenosis with increased pulmonary blood flow been recognized. Four symptomatic infant cases are described in which the clinical diagnosis was large interventricular septal defect. Hemodynamic study showed the presence of associated pulmonic stenosis. Features suggesting that there is an overriding aorta in these patients, and that they, therefore, form an atypical group within the tetralogy of Fallot, are presented. The diagnosis has been confirmed in one case at autopsy. Their differentiation from clinically similar malformations as well as the surgical problem they pose is discussed.
