Abstract. Physiologically corrected transposition of the great arteries (cTGA), defined by discordant atrioventricular and ventriculoarterial connections, is an uncommon congenital cardiac malformation. It rarely exists without associated cardiac anomalies, the most common of which are ventricular septal defect, pulmonary outflow obstruction, tricuspid valve (systemic) deformity, and rhythm disturbances. Conversely, hypoplasia of the systemic ventricle and systemic inflow or outflow obstructions have seldom been reported, although their recognition may significantly influence surgical repair and the patient's prognosis. We report a case of cTGA with complete heart block, moderate hypoplasia of the systemic ventricle, and severe aortic coarctation that was echocardiographically diagnosed in utero at 30 weeks' gestation because of fetal growth retardation and persistent fetal bradycardia. After delivery the patient underwent epimyocardial pacemaker implantation and aortic coarctation repair at 2 weeks of age. Unfortunately, the patient died on the seventh postoperative day because of systemic ventricular hypertrophy. Although it is well known that fetal echocardiography may reliably diagnose uncommon congenital cardiac malformations, to the best of our knowledge, this paper represents the first reported case of antenatal diagnosis of this complex anomaly.
