Percutaneous closure of patent foramen ovale in a patient with situs viscerum inversus.

We describe the case of a patient with situs viscerum inversus totalis in whom we performed percutaneous closure of a patent foramen ovale. This case report may represent a further contribution to illustrate instrumental and interventional issues to consider in patients with situs viscerum inversus; it is also an example in which a background in embryology and congenital heart disease may aid cardiologists for the well-tolerated and effective diagnosis and treatment of adult patients with cardiac anomalies.
