A analysis workforce led by Ida Anna Cappello of the Coronary heart Rhythm Administration Centre of the College Hospital Brussels (VUB) has made vital strides within the area of biomedical engineering by growing revolutionary 3D printed surgical guides for cardiovascular procedures. The workforce’s analysis, performed in shut collaboration with cardiologists and cardiac surgeons, holds the potential to revolutionize surgical accuracy in advanced coronary heart surgical procedures.
The analysis focuses on creating patient-specific, 3D-printed surgical guides to be used in hybrid electrophysiology surgical procedures. These procedures, carried out by electrophysiologists and cardiac surgeons, contain open chest surgical procedures the place precision is paramount. The customized surgical guides, constructed utilizing a affected person’s CT scan and LGE-MRI knowledge, present a transparent visible help that helps surgeons rapidly and precisely find key remedy areas inside the coronary heart, such because the optimum location to construct the bypass vein after narrowed coronary artery or necrotic zones after extended ischemia on account of atherosclerotic plaques.
“Despite advances in medical technology, cardiac surgeons often rely on 2D images to locate the optimal place for bypass grafts implantation. It’s surprising that in 2024, we are still using such outdated methods,” says Cappello. “My research aims to change that, offering a practical, precise tool to improve outcomes for patients.”
Cappello and the workforce developed two kinds of surgical guides:
Bypass surgical procedure information: this mannequin assists surgeons in figuring out the optimum web site for bypass graft placement, considering components such because the vessel diameter and the gap from blockages.
Ventricular tachycardia ablation information: this information helps pinpoint areas of scar tissue, which might trigger life-threatening coronary heart arrhythmias, in order that surgeons can exactly burn or “ablate” the tissue to forestall irregular electrical alerts from inflicting harmful coronary heart rhythms.
“A major highlight of the work is the potential to combine both guides into one surgical tool, allowing for simultaneous treatment of coronary artery disease and arrhythmias during a single procedure. This dual-treatment capability could significantly reduce surgery time and improve recovery outcomes for patients.” Cappello continues.
Cappello performed intensive experiments, together with trials on pig hearts in saline options, to make sure the protection and efficacy of the supplies used for these surgical guides. Her findings have been printed in a number of tutorial journals, and she or he has co-authored 5 papers in beneath two years.
