Case ReportsVery late erosion of Amplatzer septal occluder device presenting as pericardial pain and effusion 8 years after placement.
We report the case of a very late erosion of an Amplatzer septal occluder (ASO) device more than 8 years after implant, presenting without signs of cardiac tamponade. To date, this case represents the longest period between ASO device implantation and clinical presentation following erosion. The overall rate of device erosion remains low, and the majority reported so far has occurred early, but clinicians should remain alert to the possibility of very late erosion in patients with ASO devices.

Recurrent events after percutaneous closure of patent foramen ovale.
To determine the incidence of symptomatic recurrent embolic events after patent foramen ovale (PFO) closure and potential causes for these events. ⋯ The incidence of symptomatic embolic events after PFO closure is low. Most recurrent events are related to coexistent conditions associated with thromboembolic risk rather than residual shunts.

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.

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.
