Clinical features of single ventricle with congenitally corrected transposition

Univentricular heart in adults: report of nine cases with review of the literature

Nine patients with univentricular heart 17 years of age or older were followed up for a mean duration of 13 years (range 5 to 26 years). Five patients had type A and four patients had type C univentricular heart. Pulmonary stenosis was present in eight of nine patients. Palliative shunt surgery was performed in seven patients, ventricular septation was performed in one patient, and no surgical intervention was performed in one patient. Eight patients were in New York Heart Association functional class II and one patient was in New York Heart Association functional class III. Long term follow-up of these patients suggests that a selected group of adults with univentricular heart may achieve a relatively long survival and good functional class with conservative management.

Corrected transposition of the great vessels: a vectorcardiographic study

The vectorcardiograms (VCGs) of two groups of patients with corrected transposition of the great vessels (CTGV) were studied; the first, group A, included 17 patients with CTGV in "situs solitus,", characterized by leftward orientation of the cardiac apex; the second group, group B, with three patients, presented CTGV in "situs solitus" and apex to the right. All cases had one or more associated defects: ventricular septal defect, atrial septal defect, pulmonic stenosis or tricuspid insufficiency.

The differential diagnosis of levo-transposed or malposed aorta. An angiocardiographic study

The levo-transposed aorta has previously been considered diagnostic of corrected transposition of the great arteries and hence ventricular inversion in situs solitus. Increasing experience with conotruncal abnormalities has shown that an abnormally leftward aorta may be found in patients with normally related ventricles (D-ventricular loop) and hemodynamically complete transposition of the great arteries; anatomically corrected L-malposition of the great arteries; and rarely in patients with D-ventricular loop, double outlet right and left ventricles. Thus the levo-positioned aorta should suggest a wider spectrum of cardiovascular abnormalities than previously thought. The specific angiocardiographic features of levo-transposition, anatomically corrected malpositions, and D-ventricular loop with levo-transposed aorta are presented in detail; and their differential diagnosis from the very uncommon D-loop, double outlet right and left ventricles with an L-malposed aorta is considered. The role of selective biplane angiocardiography in the assessment of these conotruncal abnormalities is stressed.
