Key result
Intraoperative hybrid stent placement allows delivery of larger, stronger stents for pulmonary vein stenosis.
Why the study?
Pulmonary vein stenosis is often progressive and severe with common restenosis after surgical and percutaneous angioplasty, necessitating multiple reinterventions.
Describes a collaborative intraoperative hybrid stent placement technique for pulmonary vein stenosis to allow delivery of larger, stronger stents and potentially reduce restenosis.
May support hybrid stenting for larger devices in pulmonary vein stenosis; hypothesis-generating and requires prospective validation.
Pulmonary vein stenosis (PVS) is often progressive and severe. Surgical and percutaneous angioplasty are acutely successful; however, restenosis is common and many patients require multiple reinterventions. We perform intraoperative "hybrid" stent placement to deliver larger, stronger stents. Hybrid stent placement is well described for pulmonary arterial stenosis (PAS). The PAS data demonstrate that smaller stents are associated with rapid in-stent restenosis. Data from PVS in adults demonstrate superior outcomes with larger stents. Hybrid stent placement requires a strong collaborative effort between congenital heart surgeons and interventional cardiologists.

Shell et al. (2015) studied Pulmonary vein stenosis (PVS). Intraoperative hybrid stent placement was evaluated. Intraoperative hybrid stent placement allows for the delivery of larger, stronger stents to treat pulmonary vein stenosis, requiring collaboration between surgeons and interventional cardiologists.
