title: Qualitative radionuclide angiocardiography in the diagnosis of corrected transposition.
abstract: Seven patients with corrected transposition were studied by qualitative radionuclide angiocardiography. In four patients with situs solitus with apex on the left, the pulmonary artery was in a medial and posterior position, to the right of the aorta, with its root attached to the morphological left ventricle positioned on the right. The aorta arose from the ventricle placed on the left and had an anterior position. The ventricle located on the right has a triangular shape. In the case of situs solitus with dextroversion, the pulmonary artery was to the right of the aorta and had a right-to-left direction. The ventricle placed on the right was ovoid. In one single case of situs inversus with levoversion, the pulmonary artery was on the left, emerging from the morphological left ventricle placed on the left, and was ovoid in shape, while the aorta was on the right arising from the morphological right ventricle. In one case of situs inversus with dextrocardia, atrioventricular relationships were the same as in levoversion but the apex was on the right and the morphological left ventricle was triangular. Qualitative radionuclide angiocardiography is a simple and non-invasive method for obtaining morphological data for the precise diagnosis of corrected transposition.
