Introduction: Echocardiography is essential for diagnosing and assessing the severity of perioperative structural and functional heart disease. Yet, educational opportunities to better understand echocardiography-based cardiac anatomy remain limited by the two-dimensional display, lack of anatomic details, variability of heart models, and costs and global access of training.
Methods: We performed micro computed tomography of human heart specimens not suitable for orthotopic transplantation. We created high-resolution computational 3D models of different human hearts, sliced them in the different recommended American Society of Echocardiography views, and 3D printed them using different materials.
Results: We scanned, 3D modeled, and 3D printed a variety of human hearts both healthy and diseased. We have made the models available in the cardiac operating rooms and routinely use them for teaching anesthesia residents and cardiothoracic anesthesia fellows about basic and advanced echocardiographic views, cardiopulmonary bypass cannulation strategies, and valvular pathology and planned interventions.
Conclusion: We have generated a library of 3D printed hearts to display the recommended echocardiographic views as a unique educational tool designed to safely accelerate the understanding of absolute and relative human cardiac anatomy and pathology, especially related to gaining advanced appreciation of clinically employed perioperative echocardiography.

Department of Internal Medicine, Erasmus MC Cardiovascular Institute, University Medical Center Rotterdam, Rotterdam, The Netherlands.
Purpose Of Review: The purpose of this review is to provide an overview of the current status of lipid-lowering therapy utilization and lipid goal attainment in women. We focus on lipid-lowering therapy in individuals with and without established atherosclerotic cardiovascular disease, as well as familial hypercholesterolemia. Additionally, this review aims to explore the underlying mechanisms driving these sex differences and to identify existing knowledge gaps in this area.

Swine are increasingly utilized in cardiovascular research due to their anatomical and physiological similarities to humans, particularly for studying diastolic dysfunction. While MRI offers excellent structural imaging, echocardiography provides superior real-time assessment of diastolic parameters. To address the lack of standardized methods and reduce variability across studies, we present a comprehensive guide for performing echocardiography in Yorkshire pigs, detailing anatomical considerations, equipment requirements, and technical approaches.

Artificial intelligence (AI) offers promising solutions for many steps of the cardiac imaging workflow, from patient and test selection through image acquisition, reconstruction, and interpretation, extending to prognostication and reporting. Despite the development of many cardiac imaging AI algorithms, AI tools are at various stages of development and face challenges for clinical implementation. This scientific statement, endorsed by several societies in the field, provides an overview of the current landscape and challenges of AI applications in cardiac CT and MRI.

Background: Some adult transplant surgeons consider transplant to be contraindicated in patients receiving palliative care (PC). Little is known about pediatric transplant surgeons' attitudes toward PC. We sought to ascertain pediatric kidney transplant surgeons' perspectives regarding the routine integration of PC for children with chronic kidney disease.
