Twenty cases of corrected transposition of the great vessels of the bulbo-ventricular inversion type, either lone or combined with other intracardiac anomalies, were analysed. Rhythm and/or atrio-ventricular conduction disturbances were common to all groups of cases. QRS pattern changes were found to be related both to ventricular inversion and to ventricular hypertrophy. Isolated corrected tra...

The physician dealing with congenital cardiac disease is not unlikely to be confronted with cases in which there is an abnormal relation between the great vessels (transposition). In analysing such a case, he attempts to determine whether or not there is some obstruction to pulmonary flow, and furthermore whether or not two ventricles are present, and, if so, which artery arises from which vent...

A 39-year-old man was referred for echocardiography because of dyspnoea, chest pain and murmur. Main finding was a globular morphology of left ventricle with apical hypertrophy and a seemingly cleft mitral valve with mild mitral regurgitation. Trans-oesophageal echocardiography confirmed the ventricular hypertrophy and regurgitation but showed the aortic valve to lie anteriorly and to the left ...

SINCE the incidence of transposition of the great vessels is approximately one in 20,000 live births, and since many of the infants affected have short lives, the prevalence of the condition is not such that the practitioner will see many cases. Still, the interest of the physician in these patients should transcend the pragmatic aspects of the minor public-health problem presented by care of t...
