Right ventricular dysfunction and pulmonary valve replacement after correction of tetralogy of Fallot.

Background: Correction of tetralogy of Fallot often leads to pulmonary regurgitation, sometimes warranting pulmonary valve replacement, for which indications and timing to achieve optimal results are not yet clear. This retrospective study describes follow-up and reinterventions in our tetralogy of Fallot population.

Methods: Review of all consecutive patients operated on for tetralogy of Fallot between 1977 and 2000 was conducted.
