Axial cineangiography in congenital heart disease. Section II. Specific lesions.

Abstract

The value of axial cineangiography in several forms of congenital heart disease serves as an illustrated supplement to Section I. These techniques visualize defects in the entire ventricular and atrial septum. In persistent atrioventricular (A-V) canal, it is possible to visualize all parts of both septa, status of the A-V valves (two valves versus a common A-V valve), and if a common A-V valve, its degree of override. In tetralogy of Fallot, the bifurcation of the pulmonary trunk, entire ventricular septum and coronary arteries are vividly shown. The presence of true and confluent pulmonary arteries versus systemic or bronchial arteries in pseudotruncus is clearcut. In double outlet right ventricle or in transpositions with or without double outlet right ventricle, the mitral valve-semilunar valve relationships, the left ventricular outflow tract, subpulmonary region and a straddling tricuspid valve are well demonstrated. In asymmetric septal hypertrophy, biventricular angiography may be circumvented.
