Las cardiopatías congénitas son las malformaciones presentes al nacimiento más frecuentes, y tienen un impacto muy significativo a nivel clínico de consumo de recursos sanitarios, de estancia y mortalidad hospitalaria (Tabbutt, S.,2012). Ello hace que las cardiopatías congénitas supongan un reto sanitario y, por tanto, su peso en los programas...

In the report by Pumacayo-Cardenas et al1 in this issue of JACC: Case Reports, the authors describe circumferential constriction of the heart at the level of the ventricular cone combined. The authors suggest that this may be the result of an abnormal remodeling of the trabecular layer and incomplete formation of the papillary muscles. (summary)

Background Malformation of the right atrium is a rare cardiac abnormality and is usually reported as isolated malformation in the literature. Case presentation Prenatal giant atrial dilatation in an asymptomatic infant was treated surgically at 18 months of age, due to potential risk of thrombosis and arrhythmias. Post-surgical...

We have been dealing with an unprecedented global health crisis for nearly 2 years now. This started after an outbreak of atypical pneumonia of unknown etiology that was described in late December 2019 in China's Wuhan Province, the etiologic agent causing this pneumonia episode was identified as a novel coronavirus named "Severe Acute...

Cardiac fibromas (CF) are the second most common cardiac tumors in children. They can be aggressive tumors despite their benign histopathologic nature, accounting for the highest mortality rate among primary cardiac tumors. CF usually presents a progressive growth and spontaneous regression is rare. Therefore, a complete surgical excision is...

This is a 7-years single institution study on low-cost cardiac three-dimensional (3D) printing based on the use of free open-source programs and affordable printers and materials. The process of 3D printing is based on several steps (image acquisition, segmentation, mesh optimization, slicing, and three-dimensional printing). The...

Background: Improvements in outcomes for patients with congenital heart disease (CHD) have increased the need for diagnostic and interventional procedures. Cumulative radiation risk is a growing concern. MRI-guided interventions are a promising ionizing radiation-free, alternative approach. Purpose: To assess the feasibility of MRI-guided...

While the clinical gold standard for pressure difference measurements is invasive catheterization, 4D Flow MRI is a promising tool for enabling a non-invasive quantification, by linking highly spatially resolved ve- locity measurements with pressure differences via the incompressible Navier–Stokes equations. In this work we provide a validation...

Dispositivo de control de flujo de sangre en un vaso sanguíneo. La invención describe un dispositivo (1) de control de flujo de sangre en un vaso sanguíneo que comprende una cadena (2) formada por eslabones donde el ángulo máximo de giro entre cada par de eslabones está limitado, donde la cadena (2) tiene una porción proximal (2p) dotada de un...

Three-dimensional (3D) engineered cardiovascular tissues have shown great promise to replace damaged structures. Specifically, tissue engineering vascular grafts (TEVG) have the potential to replace biological and synthetic grafts. We aimed to design an in-vitro patient-specific patch based on a hybrid 3D print combined with vascular smooth...
