Kartagener syndrome with rare constellation of situs inversus, mesocardia, and congenitally corrected transposition of great arteries

Kartagener syndrome (KS) is a rare autosomal recessive condition with a triad of situs inversus, bronchiectasis, and sinusitis. In majority of cases, the heart is structurally normal; however, rarely intracardiac anomalies can be seen in patients with KS such atrial or ventricular septal defects and pulmonary stenosis. We present a rare coexistence of situs inversus, mesocardia, and corrected transposition of great arteries in a young adolescent male with KS diagnosed on computed tomography angiography.
