Congenitally corrected transposition of the great arteries associated with total situs inversus in an asymptomatic patient

Corrected transposition of the great arteries (c-TGA) is a complex and unusual abnormality occurring in less than 1 percent of people with congenital heart disease. This condition involves atrioventricular discordance and ventriculoarterial discordance (double discordance). Associated anomalies occur in up to 98% in some series and consist of VSD (75% of cases), pulmonary or subpulmonary stenosis (75% of cases) and systemic (tricuspid) valve anomalies (Ebstein-like in 30% of cases). Only 1-10% of individuals with c-TGA have no associated defects.
We report a case of an asymptomatic 46-year-old man with c-TGA with situs inversus totalis. He was referred by a general practitioner because of abnormal auscultation findings (Heart sounds were noted to be louder over the right precordium with the point of maximal impulse on the right side of the chest and 2/6-degree systolic murmur on the right sternal border). Follow-up was decided because of the patient was being asymptomatic.
