Congenitally correct transposition of the great arteries (cc-TGA) is an extremely rare congenital cardiac malposition. They are usually detected by echocardiography in the fetal period. This case report describes a 58-year-old female patient who presented with tachycardia. The combination of cc-TGA and isolated levocardia is incidentally diagnosed by transthoracic echocardiography and cardiac magnetic resonance imaging.
