Catheter ablation of the atrioventricular node slow pathway sans fluoroscopy in a patient with situs inversus totalis

Situs inversus, also known as situs transversus or situs oppositus, is a rare congenital anomaly with an incidence of ∼0.01% in the general population.1 It is classified as either partial or total.1 Situs inversus totalis is the most common form of congenital visceral ectopia and it is caused by visceral malrotation during the embryonic stage.1 In these individuals, there is complete transposition (right-to-left reversal) of the heart and the abdominal organs, whereas the relationship between the viscera is preserved.
