Angled views in cineangiocardiography of congenital heart disease.
Simple and compound sagittally angled views of the heart obtained cineangiocardiographically with a parallelographic U-arm device were evaluated clinically in 132 patients with congenital heart disease. The principle advantage of the apparatus was the case with which axial and oblique projections were obtained without repositioning of the patient, although rotation and angulation of the image intensifier-X-ray tube unit resulted in some increase in scattered radiation. Certain angled views, particularly the 40 degree cranial and the compound 25 degrees cranial/70 degrees left oblique projections, were better than standard frontal and lateral views for visualization of pulmonary arteries in the mediastinum, in ventricular septal defects and anomalies of the left ventricular outflow tract.
