This study compares two treatments for persistent atrial fibrillation (AF) that lasts more than 7 days but less than 2 years: electrical cardioversion (a shock to reset your heart rhythm) versus catheter ablation (using radio waves to fix the heart's electrical pathways). It aims to find which option works better for patients like you.

Boston, MassachusettsAges 60 years+ - NCT06146751Recruiting
Improved MRI to detect blood clots in the heart
This trial tests a new type of MRI with a special dye (ferumoxytol) to better find blood clots in the heart.
