Published: November 2021

IntroducciÓn: Los defectos cardíacos congénitos constituyen el 30% de todas las anomalías congénitas. La prevalencia es de 8/1,000 recién nacidos vivos, sin predominio de género. Para una planificación quirúrgica óptima es esencial una evaluación precisa de la anatomía en los defectos cardíacos congénitos. Las modalidades de imagen como el ecocardiograma, la angiografía por cateterismo cardíaco, la tomografía computarizada (TC) o la resonancia magnética (RM) se utilizan de forma regular para el diagnóstico de las cardiopatías congénitas. Estos métodos pueden proporcionar reconstrucciones virtuales en reconstrucción volumétrica o 3D, pero no réplicas táctiles reales de la anatomía cardíaca.

Objetivo: Realizar modelos de corazón impresos en 3D con la finalidad de proporcionar réplicas táctiles 3D reales de la anatomía cardíaca para visualizar de forma detallada todas las perspectivas posibles de las estructuras extracardíacas o intracardíacas.

MÉtodos: Los datos de la imagen se obtuvieron en formato DICOM, se editaron en el paquete de software "3D slicer 4.3" y se exportaron para la impresión en formato de archivo (.stl).

Resultados Y Conclusiones: Con la impresión 3D se puede evaluar de forma detallada la anatomía intracardíaca y extracardíaca con modelos cardíacos en tiempo real. Esta técnica es de gran utilidad, sobre todo en los defectos cardíacos congénitos complejos, ya que permite hacer una planificación precisa del procedimiento quirúrgico.

Introduction: Congenital heart disease makes up for 30% of all congenital anomalies. The prevalence is 8/1,000 live newborns, without predominance of gender. Imaging methods such as echocardiography, angiography, computed tomography or magnetic resonance imaging must be routinely used in congenital heart disease. The mentioned methods can provide virtual reconstructions in volumetric reconstruction or in three dimensional (3D), but only 3D-printed heart models can provide real 3D tactile replicas of cardiac anatomy.

Objective: To make 3D printed heart models in order to provide real 3D tactile replicas of the cardiac anatomy that allow a detailed visualization from all possible perspectives, either of extracardiac or intracardiac structures.

Methods: This information is useful for surgical decision making, especially in patients with complex cardiac defects. DICOM, edited in a software package “3D slicer 4.3” and exported for printing in file format (.stl).

Results And Conclusions: With 3D printing, the intracardiac and extracardiac anatomy can be evaluated in detail with real-scale cardiac models of the patient, avoiding unexpected findings. This technique is very useful especially in complex congenital heart defects, since it allows precise planning of the surgical procedure.

Imaging Approach to Pulmonary Hypertension.

Radiol Clin North Am

March 2025

Department of Radiology and Biomedical Imaging, University of California San Francisco, M-391 Box 0628, 505 Parnassus Avenue, San Francisco, CA 94143, USA.

Pulmonary hypertension is a rare but important clinical problem that presents a sometimes challenging diagnostic dilemma. The diagnosis of pulmonary hypertension relies on a combination of clinical testing and radiologic imaging, with chest computed tomography (CT) often serving as the primary imaging modality for comprehensive evaluation of the chest. Chest CT can be used to evaluate for causes of pulmonary hypertension including chronic lung disease, pulmonary artery obstruction, and congenital heart disease.

Mixed reality for preoperative planning and intraoperative assistance of surgical correction of complex congenital heart defects.

J Thorac Cardiovasc Surg

January 2025

Division of Cardiology, The Hospital for Sick Children, Toronto, ON, Canada; Center for Image Guided Innovation and Therapeutic Intervention, The Hospital for Sick Children, Toronto, ON, Canada.

Objectives: Mixed reality (MixR) is an innovative visualization tool that presents virtual elements in a real-world environment, enabling real-time interaction between the user and the combined digital/physical reality. We aimed to explore the feasibility of MixR in enhancing preoperative planning and intraoperative guidance for the correction of various complex congenital heart defects (CHDs).

Methods: Patients underwent cardiac computed tomography or cardiac magnetic resonance and segmentation of digital imaging and communications in medicine (DICOM) images was performed.

Reaching competency in congenital heart surgery (CHS) requires lengthy and rigorous training. Due to patient safety, time limitations, and procedural complexity, the intraoperative setting is not ideal for technical practice. Surgical simulation using synthetic, biological, or virtual models is an increasingly valuable educational tool for technical training and assessment.

Endoscopic Mitral Surgery in Noonan Syndrome-Case Report and Considerations.

J Clin Med

Department of Surgery IV, George Emil Palade University of Medicine, Pharmacy, Science and Technology of Targu Mures, 38 Gheorghe Marinescu Street, 540139 Targu Mures, Romania.

: Totally endoscopic techniques have become increasingly popular in cardiac surgery, with minimally invasive mitral valve repair emerging as an effective alternative to median sternotomy. This approach could be particularly advantageous for patients with Noonan syndrome, who often present with structural thoracic anomalies and other comorbidities like bleeding disorders. Endoscopic mitral valve surgery is rapidly establishing itself as the new standard of care for mitral valve operations, demonstrating both safety and efficacy.
