Comparing High-Density Electroanatomical Mapping and MRI: a step forward in myocardial characterization in non-ischemic cardiomyopathy

Dr. Francis Marchlinski highlights new research comparing high‑density electroanatomical mapping with cardiac MRI in non‑ischemic cardiomyopathy. He explains how omnipolar mapping more accurately reflects MRI‑defined scar patterns—especially in deeper layers—and why this technology may offer a valuable alternative when MRI is limited or unavailable. A concise look at emerging tools reshaping arrhythmic risk assessment.
