Redo aortic valve surgery in a case of dextrocardia with situs inversus totalis

Abstract

Introduction: Dextrocardia is a rare congenital cardiac anomaly where the base-apex axis of the heart is directed to the right side. It may be associated with situs solitus, situs inversus, or situs ambiguous. Such cases are technically challenging when heart surgery is needed.

Presentation of case: We presented a case of a patient with dextrocardia and situs inversus totalis, who had severe aortic bioprosthetic valve degeneration needing a redo aortic valve replacement. Our operative strategy was to change the position of the main surgeon to the left side of the patient to perform most surgical steps.

Discussion: A meticulous pre-operative surgical plan involving the whole team was very important for a smooth intra-operative course and a favourable outcome. Regarding the position of the main surgeon standing on the left side of the patient, we believed this surgical team arrangement added much to the technical ease for the procedure, since the anatomy was opposite to what our minds are used to. Also, computed tomography scan played a crucial role for a proper preoperative anatomical evaluation and surgical planning.

Conclusion: Our approach with the surgeon on the left side provided excellent exposure for redo aortic valve replacement in dextrocardia with situs inversus totalis. This surgical management played an important role for the good result in this technically challenging scenario.
