Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

Atrial fibrillation (AF) impacts the lives of 30 million people worldwide. Pulmonary vein isolation (PVI) by catheter ablation is effective for paroxysmal AF, but the success rate remains marginal at 60-80%. For persistent AF, defined as continuous AF that sustains longer than 7 days, the success rate is even lower. The low success rate of AF ablation reflects the fact that there is no effective target identified to modify the underlying substrate beyond PVI. Recently, investigators have made an exciting discovery that higher mean CT attenuation values of peri-atrial fat tissue, correlated with inflammatory fat, are associated with higher incidence of recurrence after AF ablation. In this protocol, investigators will investigate the clinical significance of peri-atrial inflammatory fat tissue in AF using ultra-high resolution CT.

A profile link is shown only when the registered name resolves to a person record with a confident, namesake-checked match; ambiguous names stay unlinked.

Sites

1 registered facility, with the per-site recruitment status where the registry publishes one. ClinicalTrials.gov does not publish per-site enrollment counts.

United States

Johns Hopkins Hospital
Baltimore, Maryland, United States

Site investigator names are published by ClinicalTrials.gov only while a study recruits, so completed studies list sites without them.
