We present the use of pulmonary vasodilators in three adult patients with unrepaired tetralogy of Fallot, pulmonary atresia, aortopulmonary collaterals, and segmental pulmonary arterial hypertension. Patients improved by 1–2 NYHA classes with modest exercise-tolerance increase, and remained stable without side effects during 2.5, 10, and 14 years. Literature review revealed five studies with pulmonary vasodilators in heterogeneous, mostly repaired patient populations.
