Background The Tetralogy of Fallot (TOF) is a frequent cardiopathy in our days, corresponding to 7% of the congenital cardiopathies. However it is acknowledged that one of the main causes of reintervention in these patients is the presence right ventricular failure secondary to pulmonary valve insufficiency (IP) leading the patient to intolerance to exercise, ventricular tachycardia and sudden death. The aim of our investigation is describing our experience of those patients subjected to (TOF) correction who have required a pulmonary valve replacement.
