From 3D Prints to VR Hearts: Medicine reimagined by 3D tech. | Dr.Mahesh Kappanayil | TEDxASM Kochi

Quick Overview

Dr. Mahesh Kappanayil details how leveraging 3D printing and Virtual Reality (VR) technology allowed his team to successfully plan and execute a complex surgery on a young child with an extremely rare congenital heart defect, transforming medical planning from 2D interpretation to immersive 3D collaboration.

Key Points: The presentation focuses on using 3D printing and VR to plan surgery for a child with an extremely rare congenital heart defect involving four chambers, two sets of veins, two arteries, and four valves. The surgeon's team successfully used 3D modeling and 3D printing to create a life-sized replica of the child's heart defect to facilitate planning and execution of the complex surgery. The use of 3D models and VR tools allowed the multidisciplinary surgical team (cardiologists, cardiac surgeons, plastic surgeons, etc.) to clearly understand the 3D anatomy and simulate surgical steps, reducing complication risks. The young patient, who initially struggled to breathe and eat due to the defect, was successfully operated on after the team used the 3D printed model of his rib cage (built using his ninth rib) for planning. The speaker credits the success to the collaboration between medical professionals and young, tech-savvy engineers who developed VR tools for medical visualization, contrasting this with traditional 2D scan interpretation. The speaker highlights the inspiration drawn from the child's tech-enthusiast father, who had already built home automation circuits and later joined the team as a PhD scholar to develop VR tools for medicine.

Context: Dr. Mahesh Kappanayil, a pediatric cardiologist, shares his experience at TEDx ASM Kochi on revolutionizing surgical planning for complex congenital heart defects using cutting-edge technology, primarily 3D printing and Virtual Reality (VR). He recounts a specific case of a 17-year-old patient with a highly complex heart anomaly whose successful operation was contingent on moving beyond traditional 2D medical scans to immersive 3D modeling and collaborative planning.
