3D virtual heart helps identify potential defibrillator implant patients

Researchers from Johns Hopkins University have developed a non-invasive method to determine a patient’s risk of cardiac arrhythmia and the appropriateness of a defibrillator implant using a 3D virtual heart assessment tool, according to results of a study published online in the journal Nature Communications.

The personalized virtual heart, which was created using pre-implant MRI scans, can predict the risk of sudden cardiac death using a new digital approach that yields more accurate assessments than current blood-pumping measurements, said study co-author and biomedical engineering professor Natalia Trayanova, PhD.

"Our virtual heart test significantly outperformed several existing clinical metrics in predicting future arrhythmic events," she said in a university press release. "This non-invasive and personalized virtual heart-risk assessment could help prevent sudden cardiac deaths and allow patients who are not at risk to avoid unnecessary defibrillator implantations."

A total of 16 cardiology practices from 12 states settled with the DOJ to resolve allegations they overbilled Medicare for imaging agents used to diagnose cardiovascular disease. 

CCTA is being utilized more and more for the diagnosis and management of suspected coronary artery disease. An international group of specialists shared their perspective on this ongoing trend.

The new technology shows early potential to make a significant impact on imaging workflows and patient care.
