Percutaneous recanalization of totally occluded pulmonary veins after pulmonary vein isolation-intermediate-term follow-up.
Review mid-term follow-up of percutaneous intervention for post ablation total pulmonary vein occlusion (PVO). ⋯ Recanalization of total PVO can be accomplished with reasonable mid-term patency, improved symptoms, and lung perfusion. Reocclusion is common, but vessel growth is often observed allowing placement of a reasonably sized stent at a second intervention. Staged intervention is often necessary to maintain patency.

Morphology of the patent ductus arteriosus does not preclude successful patent ductus arteriosus stent implantation in high-risk patients undergoing hybrid stage I palliation: recommendations to optimize ductal stent positioning.
To describe patent ductus arteriosus (PDA) stenting regardless of ductal morphology in high risk patients with hypoplast physiology undergoing hybrid stage I palliation (PDA stenting and placement of bilateral pulmonary artery bands). ⋯ Mid- to long-term follow-up indicates that PDA stents remain widely patent regardless of ductal morphology until comprehensive stage II repair.
