[Corrected transposition of great vessels in adult age]

Two adult cases of corrected transposition of the great arteries are presented. One of the two males had associated ventricular septal defect, the other one presented as an isolated anomaly. The characteristic clinical features are: loud second heart sound with audible pulmonic component of the left sternal border in the absence of pulmonary hypertension. Abnormal precordial impulse upon palpation. Chest X-ray shows absence of pulmonic segment and of the aortic knob with the contour of the ascending aorta to the left of the mediastinum. Ecg anomalies may be multiple; typically anomalous septal Q-waves are consistently absent. Corrected transposition is well tolerated even into adulthood. Prognosis is dominated by assiciated anomalies.
