It was the first time the technique has been used in catheter ablation, where the organ's innerlining is ablated or "burned" to treat irregular heartbeats.
When gluten hits the gut in someone with celiac disease, it sets off an immune reaction which kills off the cells forming the innerlining of the small intestine.
For certain heart conditions, antibiotics are recommended about one hour before invasive medical procedures to prevent a condition called infective endocarditis, which is a potentially life-threatening bacterial infection of the innerlining or valve within the heart.
