To make the device, researchers first convert medical images of a patient\u2019s heart into a 3D computer model, then 3D-printed with polymer-based ink to produce a soft, flexible shell shaped like the patient\u2019s heart. The team can use this method to print a patient\u2019s aorta. The researchers have also developed sleeves that wrap around the printed heart and aorta and can be controlled to mimic the patient\u2019s blood-pumping ability.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter\"><img  decoding=\"async\"  src=\"data:image\/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABAQMAAAAl21bKAAAAA1BMVEUAAP+KeNJXAAAAAXRSTlMAQObYZgAAAAlwSFlzAAAOxAAADsQBlSsOGwAAAApJREFUCNdjYAAAAAIAAeIhvDMAAAAASUVORK5CYII=\"  alt=\"\"  class=\" pk-lazyload\"  data-pk-sizes=\"auto\"  data-pk-src=\"https:\/\/lh5.googleusercontent.com\/VXliI3p7LXWu1j9Zp8WhT5K0WvIJ2zrJjGulwppr3_Vw5flWgQUH2_idnZq4A9yHjQgIQTsSdpOAiWSJH0-_ipfCOQXNCutlUQlYAWagygDRGMAQlvdHblBxmLnSq-sfA1hzr6tnOC6-0qyxOITdJcc\" ><figcaption class=\"wp-element-caption\">Researchers showcase the custom 3D-printed \u201crobotic\u201d heart. (Melanie Gonick\/MIT, 2023)<\/figcaption><\/figure>\n<\/div>\n\n\n<p>Researchers could accurately match heart-pumping pressures and flows previously recorded for each patient in their respective printed hearts to test whether the custom robotic heart worked. The device could create a printed heart and aorta model, allowing doctors to implant various valve designs to determine which design provides the best function and fit for that patient. The models could also be used to test therapies for different types of heart disease.<\/p>\n\n\n\n<p>The researchers created custom replicas of actual patients\u2019 hearts using medical scans from 15 patients with aortic stenosis. The researchers demonstrated that each model heart could accurately recreate the same heart-pumping pressures and flows that had previously been measured in each patient. The valves were implanted in the printed aortas modeled after each patient to see if the printed heart and vessel responded similarly.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Patient-specific, 3D-printed, soft-robotic hearts\" width=\"1200\" height=\"675\" src=\"https:\/\/www.youtube.com\/embed\/52qNGqBbTQA?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe>\n<\/div><figcaption class=\"wp-element-caption\">(Massachusetts Institute of Technology\/YouTube, 2023)<\/figcaption><\/figure>\n\n\n\n<p>According to <a href=\"https:\/\/ttdd.mit.edu\/people\/luca-rosalia\" target=\"_blank\" rel=\"noopener\" title=\"\">Luca Rosalia<\/a>, a graduate student in the <a href=\"https:\/\/hst.mit.edu\/\" target=\"_blank\" rel=\"noopener\" title=\"\">MIT-Harvard Program in Health Sciences and Technology<\/a>, all hearts are unique. \u201cThe advantage of our system is that we can recreate not just the form of a patient\u2019s heart but also its function in both physiology and disease,\u201d Rosalia explained.<\/p>\n\n\n\n<p>The study was recently published in the journal <a href=\"https:\/\/www.science.org\/doi\/10.1126\/scirobotics.ade2184\" target=\"_blank\" rel=\"noopener\" title=\"\">Science Robotics<\/a>.<\/p>\n\n\n\n<h1 id=\"references\" class=\"wp-block-heading\">References<\/h1>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Chu, J.
