Abstract

Since Jatene (1976) first published a new approach to surgical correction of transposition of the great arteries (TGA), several centers have been accumulating experience with this method. At present, it is accepted that anatomic correction of TGA is a true alternative to other procedures (Mustard and Senning) [1–4]. One of the disadvantages in simple TGA is the necessity of a preliminary procedure; banding of pulmonary artery to train the left ventricle and subclavian artery to pulmonary artery shunt to increase the reduced pulmonary flow. This approach may require up to four cardiac catheterizations. We became especially interested in obtaining information about changes in pulmonary blood flow. In earlier studies, we could demonstrate changes in pulmonary flow and resistance by digital image processing of routine right ventricular (RV cineangiograms, with estimation of the arrival time (AT) of contrast bolus in the lung periphery [5]. Therefore, it seemed interesting to study the changing lung perfusion in TGA patients undergoing two-stage anatomic correction.
