Transcatheter correction of sinus venosus defect in a patient with a challenging anatomical configuration: From bench testing to clinical success.

We report successful transcatheter correction of a sinus venosus defect in a 72-year-old woman with anomalous pulmonary venous return in a challenging anatomical configuration. The procedure was facilitated by hands-on simulation training on a newly developed, perfused, 3D-printed model.
