Pulmonary vein stent implantation effective as first-line therapy for pulmonary vein stenosis
Pulmonary vein stent implantation (PSI) in patients with pulmonary vein stenosis
(PVS) is associated with a reduced risk of re-intervention and should be considered first-line therapy, according to a study.
After conducting a literature search of studies comparing pulmonary vein balloon angioplasty (PBA) and PSI in patients with PVS, 8 observational studies were identified. Of the 768 patients included with severe PVS, 487 patients between the ages of 6 months and 70 years met inclusion criteria and were analyzed.
Re-stenosis requiring re-intervention was needed in 196 of 325 veins of patients treated with PBA and 111 of 443 veins of patients treated with PSI. Pulmonary vein balloon angioplasty was associated with a significantly increased risk of re-stenosis compared with PSI.
Procedure-related complications happened in 7 of 122 patients in the PBA group and 6 of 69 in the PSI group.
No statistically significant differences were found between the groups in safety outcomes.
