Heart on the right side: A rare case report of dextrocardia with situs solitus, L-TGA (levo-transposition of the great arteries) and single ventricle physiology

Dextrocardia is a rare congenital anomaly characterized by the positioning of the heart towards the right side of the chest. The prevalence of dextrocardia with situs solitus is 1 in 30000 live births and 1 in 900000 in the adult population. We report the case of a 20-year-old male who presented with fever, shortness of breath, and an episode of epistaxis. He was found to have dengue IgM and Scrub typhus antibody positivity along with low hemoglobin, platelets, and total leucocyte count. Imaging studies revealed dextrocardia with situs solitus, single ventricle physiology, levo-transposition of great arteries (L-TGA), and moderate pulmonary stenosis. This case focuses on the importance of recognizing congenital heart diseases (CHDs) in patients with dextrocardia along with situs solitus. The patient had associated CHD with L-TGA, which is an uncommon type of CHD so this case report highlights the importance of careful evaluation of patients with suspected CHD and emphasizes the need for multidisciplinary management for the best outcomes.
