Ruptured type A aortic dissection can present with new-onset AF via left atrial hematoma compression.
Highlights a rare presentation of ruptured type A aortic dissection manifesting as new onset atrial fibrillation due to left atrial compression by a hematoma.
Consider aortic dissection in unexplained new-onset AF; single case leaves prevalence and causality open.
We report this type A aortic dissection in both ascending and descending thoracic aorta presenting with new onset atrial fibrillation. CT images confirmed the final diagnosis. The mechanism may be due to compression of the left atrium by a large haematoma.
