Total pulmonary vein diameter is a strong predictor of atrial fibrillation after coronary artery bypass graft surgery.
OBJECTIVE
Recent studies have shown that the pulmonary veins are important in atrial fibrillation (AF). This study evaluated the relationship between total pulmonary vein diameter and postoperative AF in on-pump coronary artery bypass graft (CABG) patients.


METHODS
Our study enrolled 149 patients undergoing on-pump CABG. The primary endpoint was defined as postoperative new-onset in-hospital AF. All patients underwent preoperative non-contrast tomography to measure pulmonary vein diameter.


RESULTS
The patients who developed AF had significantly greater total pulmonary vein diameters than those who remained in sinus rhythm. Logistic multivariate regression analysis revealed that only total pulmonary vein diameter was an independent predictor of the development of new-onset AF.


CONCLUSIONS
To our knowledge, this is the first report of an association between total pulmonary vein diameter and the development postoperative AF. The identification of high-risk patients using pulmonary vein diameters should facilitate preventive measures.
