Summary

Story summary

Johns Hopkins University researchers used virtual heart replicas to guide ablation for ventricular tachycardia.
In a small trial, eight of ten patients remained arrhythmia-free after treatment.
The digital twins enabled precise mapping of dysfunctional heart areas, boosting safety and effectiveness.
Researchers plan larger studies and expansions to atrial fibrillation and cancer care.
The findings were published in the New England Journal of Medicine.
