Johns Hopkins University researchers have successfully created three-dimensional (3D) personalized virtual simulations of the human heart, in order to accurately identify where cardiac specialists should electrically destroy cardiac tissue to stop potentially fatal irregular and rapid heartbeats in patients with scarring in the heart.

The results of the research suggest  a significant amount of the uncertainty around this type of procedure can be removed, the treatment can be standardized, and the variability of outcomes can be decreased.

The researchers used magnetic resonance imaging (MRI) images to create personalized heart models of 21 people who previously had successful cardiac ablation procedures for infarct-related ventricular tachycardia between 2006 and 2017.

The 3D modeling of these patients correctly identified and predicted the locations where physicians ablated heart tissue.

Johns Hopkins University researcher Jonathan Chrispin says the new technique "can help us achieve our overarching goal of improving quality of life for patients suffering from treatment-resistant ventricular tachycardia."
