Between 1976-1979, 14 patients with simple transposition of the great arteries (TGA), ranging in age from 1 month to 2 1/2 years, underwent two-stage anatomic correction. Twenty patients underwent a first-stage operation, with three early deaths (15%). After the first-stage operation the peak systolic left ventricular pressure rose from 38 +/- 6 mm Hg to(More)
In 16 patients, constituting 100% of children followed for up to 7 years after two-stage anatomic correction of complete transposition of the great arteries, clinical and electrocardiographic data, as well as cardiac catheterization data in 12 patients, were analyzed. None of them has had signs or symptoms of coronary or myocardial insufficiency after an(More)
On the basis of angiographic projections, left (n = 43) and right (n = 56) ventricular volume data were obtained in patients with tetralogy of Fallot before and after surgical repair. The postoperative patients were divided into 3 groups according to the degree of an additional volume load secondary to a residual ventricular septal defect or pulmonary(More)
Systolic and diastolic diameters of the right and left pulmonary arteries (RPAD, LPAD), descending thoracic aorta (DTAD), right ventricular infundibulum (RVID), and pulmonary and aortic valve roots at the proximal, commissural and distal levels were estimated from angiocardiograms in 24 infants, children, and adolescents without heart disease, and(More)
Twenty-two patients who underwent anatomic correction of transposition of the great arteries at the arterial level at the age of 8 weeks to 14 years were reinvestigated 1-4.6 years (mean 2.0 years) after operation. A Dacron tube was used to bridge the gap between the proximal pulmonary route and the distal pulmonary artery in four patients and a tube made(More)
Anatomic correction of transposition of the great arteries always entails circumferential anastomoses of the aorta and coronary arteries. Long-term success of this procedure is predicted on adequate growth of these anastomotic sites. To assess the size of these arteries, we performed one or two cardiac catheterization on 25 children from 1 to 53 months(More)
To evaluate the influence of the 2-stage anatomic correction of simple transposition of the great arteries on left ventricular (LV) function, pressure and angiocardiographic volume data were analyzed during resting conditions shortly before banding of the pulmonary trunk (n = 12) and before (n = 17) and after anatomic correction (n = 11), and compared with(More)
Twenty-eight children were reinvestigated by cardiac catheterization and angiography greater than 1 year after anatomic correction of transposition of the great arteries (TGA). Seventeen patients with simple TGA underwent banding of the pulmonary trunk plus or minus systemic to pulmonary artery shunt to prepare the left ventricle for anatomic correction. In(More)
To evaluate the results of the two-stage anatomic correction of simple transposition of the great arteries the size, distensibility, and histologic characteristics of the anatomic pulmonary root, which arises from the anatomic left ventricle and which we termed the functional aortic root after anatomic correction, were determined in seven patients before(More)
On the basis of 21 life-like human casts (the method is described in the first paper of this series) the influence of (a) spatial orientation, (b) cardiac phase, and (c) biplane and single-plane methods of volume calculation on the accuracy of left ventricular (LV) angiocardiographic volume determination was quantitated. The best results are obtained, when(More)
