The Effect of Coronary Arteries diameter on the Incidence of Postoperative Atrial Fibrillation
Predisposing Factors • Hx of AF • COPD • Intubation >24 hr • RCA lesion • High BNP level • Long P Wave • Long cross clamp time • Severe hypotermia • Reaction of anterior epicardial fat pad • Right atrial pacing
Evaluated Factors • Age • DM • HTN • CS • LA volume • RA volume • LV end-diastolic volume • RV end-diastolic volume • PA pressure • LM lesion • LAD lesion • LCx lesion • RCA lesion • Total coronary arteries diameter(TCD) • Ratio of LADd/TCD , RCAd/TCD , LCxd/TCD • Cross clamp time
