NT-proBNP as Marker of Ventricular Dilatation and Pulmonary Regurgitation After Surgical Correction of Tetralogy of Fallot: A MRI Validation Study.

The goal of this study is to evaluate whether NT-proBNP plasma levels may help as a screening biomarker for monitoring right ventricular dilatation, pulmonary regurgitation and the onset of heart failure in patients with repaired Tetralogy of Fallot. Our single-centre observational prospective study involved 43 patients (15.1 years, SD = 8) with corrected Tetralogy of Fallot.

3D printed models for planning endovascular stenting in transverse aortic arch hypoplasia.

Objectives: To evaluate whether three-dimensional (3D) printed models can be used to improve interventional simulation and planning in patients with aortic arch hypoplasia.

Background: Stenting of a hypoplastic transverse arch is technically challenging, and complications such as stent migration and partial obstruction of the origin of the head and neck vessels are highly dependent on operator skills and expertise.

Methods: Using magnetic resonance imaging (MRI) data, a 3D model of a repaired aortic coarctation of a 15-year-old boy with hypoplastic aortic arch was printed.
