Nonsurgical closure of a patent foramen ovale in a patient with carcinoid heart disease and severe hypoxia from interatrial shunting

We report the percutaneous transcatheter closure of a patent foramen ovale using an Amplatzer septal occluder in a rare patient with carcinoid heart disease involving both the right and left heart who presented with severe hypoxemia secondary to intra-atrial shunting. We believe this is the first report of this technique being utilized in a patient with carcinoid heart disease and it may represent an alternative to surgical closure in these patients at high risk for surgical complications.
