Objective: The aim of the study was to assess the long-term results of a selective policy toward pulmonary valve replacement in adult patients with repaired tetralogy of Fallot and severe pulmonary regurgitation. Methods: Sixty-seven patients with tetralogy of Fallot were followed up from 15 ± 3 years until 27 ± 3 years after surgery. Results: Twenty-two patients had mild-to-moderate pulmonary regurgitation. No significant changes occurred in the follow-up period. Of 45 patients with severe pulmonary regurgitation and severe right ventricular dilatation, 28 (62%) remained free of symptoms and did not undergo pulmonary valve replacement. No changes in right ventricular size or exercise capacity were found. In 3 (11%) of 28 patients, QRS duration increased to more than 180 ms. Seventeen patients had symptoms and underwent pulmonary valve replacement: 9 (54%) of 17 patients improved clinically and echocardiographically, and QRS duration shortened postoperatively. Right ventricular dimensions did not regress despite pulmonary valve replacement in 8 patients. Conclusion: Refraining from pulmonary valve replacement in asymptomatic patients led to no measurable deterioration in 25 (89%) of 28 patients. Referring symptomatic patients for pulmonary valve replacement led to an improvement in 9 (53%) of 17 patients. In 11 (24%) of 45, a selective approach led to questionable or unsatisfactory results.
