Early coronary sinus reroofing using the left atrial baffle

Surgical correction of unroofed coronary sinus, left superior vena cava, dextrocardia, and situs solitus in a 4-month-old infant consisted of reroofing the coronary sinus by means of a left atrial flap while redirecting the left superior vena cava to the right atrium. Excellent access to the left side of the left atrium was afforded by the associated dextrocardia.
