CONGENITAL CORRECTED TRANSPOSITION OF GREAT VESSELS WITHOUT CARDIAC ANOMALIES

The clinical, angiocardiographic, vectorcardiographic and phonocardiographic findings in a fifty-four year old man with uncomplicated corrected transposition of the great vessels are presented. A soft, grade 2 6 precordial systolic murmur was present, and the second heart sound at the base appeared single on auscultation but was normally and narrowly split on phonocardiogram. The P-R interval was prolonged and paroxysmal nodal tachycardia frequently occurred. The patient never manifested any evidence of heart failure and the inverted ventricles functioned well with their reversed pressure and volume loads. Sixteen well documented cases of uncomplicated corrected transposition have been reported in the American literature, and the available clinical data on seven of these cases are reviewed. The present patient is the only one in the older age group with complete antemortem documentation of all cardiovascular parameters. © 1969.
