Common arterial trunk (TAC) is a rare complex congenital heart defect
with an incidence of 6-10/100,000 live births 1.
Children born with TAC require surgery at a very young age. Operative
outcome in neonates is good and it is recommended to perform surgical
correction before heart failure, or any organ insufficiency develops2, 3. One of the most common challenges that may arise
when performing surgery on these patients is the repair of an abnormal
and severely regurgitant truncal valve (TV), which occurs in about 25%
of patients with TAC 4. There have been reports of TV
having two to six leaflets 5, 6. Among the abnormal
TV, the quadricuspid truncal valve is the most common one5. If the valve is severely regurgitant repair cannot
be avoided when performing surgical correction. Tricuspidalization of
the valve is a reproducible and safe alternative when treating this
condition with good outcomes 7, 8. Here we explain
step-by-step, a simple way to perform this procedure.
