Abstract

Two rare patients are reported with tetralogy of Fallot and congenital aortic valvar stenosis. The anatomic and developmental interrelationship between tetralogy of Fallot and truncus arteriosus is summarized. A study of 100 randomly selected postmortem cases of tetralogy revealed aortic valve pathology in 8%, myxomatous aortic valve leaflets without stenosis in 4%, bicuspid aortic valves without stenosis in 3%, and congenital aortic valvar stenosis in 1%. The frequency of systemic semilunar valve pathology in truncus was much higher (66%): moderate to marked myxomatous change in 44%, mild myxomatous change in 22%, truncal valvar stenosis in 11%, and truncal valvar regurgitation in 15%. Being aware of the tetralogy-truncus interrelationship and knowing that myxomatous aortic valves are prone to premature calcific aortic stenosis and/or regurgitation, physicians should follow the aortic valves of surgically repaired patients with tetralogy of Fallot and truncus arteriosus long term with great care. Timely aortic valvuloplasty or replacement may well prove life-saving in such patients.
