Chronic pulmonary insufficiency following transannular patch repair of tetralogy of Fallot may mandate restoration of a competent pulmonary valve. Pulmonary valve leaflets that are preserved at initial surgery may grow and develop normal morphology and subsequent valve repair may be possible. We reviewed our experience with native pulmonary valve restitution following transannular patch repair (2001-15). The cohort included 9 patients with a median age of 18.7 (range 10.6-31.3) years. Operative technique involved reapproximation of the anterior commissure of the pulmonary valve. Median length of stay was 3 days, and there were no deaths. At median follow-up of 2.0 (0.4-13.5) years, pulmonary insufficiency was graded as ≤mild (n = 4), mild-moderate or moderate (n = 4) and moderate-severe (n = 1); pulmonary stenosis was ≤mild (n = 8) and moderate (n = 1), with median peak gradient of 21 (16-64) mmHg. No patient required reintervention. At reoperation to treat pulmonary insufficiency in repaired TOF, if residual leaflets are found with favourable anatomy, restitution of the native valve should be considered. This valve-preserving technique avoids the certain failure of a bioprosthesis and is associated with favourable early outcomes. The viability of this option may influence surgeons to leave the pulmonary leaflets in situ at the time of initial repair.
