Non-invasive evaluation of new-onset atrial fibrillation after cardiac surgery: a protocol for the BigMap study.

ABSTRACT:

Aims

New-onset atrial fibrillation (NOAF) is the most common complication after cardiac surgery, occurring in 25-50% of patients. It is associated with post-operative stroke, increased mortality, prolonged hospital length of stay, and higher treatment costs. Previous small observational studies have identified the left atrium as a source of the electrical rotors and foci maintaining NOAF, but confirmation by a large prospective clinical study is still missing. The aim of the proposed study is to investigate whether the source of NOAF lies in the left atrium. The correct identification of NOAF-maintaining structures in cardiac surgical patients might offer potential therapeutic targets for prophylactic perioperative ablation strategies.
