The surgical management of truncus arteriosus poses a constant challenge
for the cardiac team treating the patient. A correct diagnosis, surgical
therapy and postoperative management are crucial for the survival of the
patient. Almost 30% of the patients show an abnormal number of leaflets
in the truncal valve, the majority being quadricuspid valves.
Additionally, around 25% of the patients show some degree of truncal
valve incompetence. We demonstrate an effective way to reconstruct
incompetent, quadricuspid valves with good postoperative outcome.
