Purpose Medium- and long-term data for the outcomes of balloon pulmonary valvuloplasty (BPV) as a treatment for isolated pulmonary valve stenosis (PS) are lacking.
Methods Patients with valvular PS who underwent BPV between 1997 and 2017 were identified from the cardiac database. Echocardiographic reports, procedural information and clinic letters were reviewed.
Results 72 patients were identified. The average length of follow-up was 8.4 years. Freedom of reintervention following BPV was 82% and 80% at 5- and 10 years respectively. 83% of reinterventions were due to residual severe PS. At both medium- and long-term follow up the incidence of moderate pulmonary regurgitation (PR) was significantly increased (p<0.05).
Conclusion BPV is a safe and effective procedure for treating severe PS. PR is a common outcome of BPV but is well tolerated.
