Congenitally corrected transposition of the great arteries (CCTGA) is a rare cardiac malformation. This anomaly is characterised by atrioventricular as well as ventriculoarterial discordance. Isolated CCTGA may cause no symptoms until adult life. Most CCTGA cases with concomitant cardiac abnormalities are symptomatic and are therefore usually diagnosed in childhood. In the majority of patients, congestive heart failure secondary to right ventricular dysfunction occurring by the fifth or sixth decade enables diagnosis. We present an oligosymptomatic 55-year-old woman with corrected transposition of the great arteries and coexisting stenosis of pulmonary trunk valve and ventricular septum defect.
