TI  - Atrial fibrillation: prevalence after minimally invasive direct and standard 
      coronary artery bypass.
PG  - 1491-5
AB  - BACKGROUND: This study identified and compared the prevalence of new-onset atrial 
      fibrillation (AFIB) following standard coronary artery bypass grafting (SCABG) 
      with cardiopulmonary bypass (CPB) and minimally invasive direct vision coronary 
      artery bypass grafting (MIDCAB) without CPB. A further comparison was made 
      between AFIB prevalence in SCABG and MIDCAB subjects with two or fewer bypasses. 
      METHODS: This is a retrospective, comparative survey. Patients with new-onset 
      AFIB who underwent SCABG or MIDCAB alone were identified electronically using a 
      triangulated method (International Classification of Diseases, 9th revision, 
      Clinical Modification [ICD-9 CM] code; clinical database word search; and 
      pharmacy database drug search). RESULTS: The total sample (n = 814; 94 MIDCAB, 
      720 SCABG) exhibited a trend toward lower AFIB prevalence in MIDCAB (23.4%) 
      versus SCABG (33.1%) subjects (p = 0.059). AFIB prevalence in the SCABG subset 
      with two or less vessel bypasses (n = 98; n = 18 single vessel, n = 80 double 
      vessels) and MIDCAB subjects (n = 94; n = 90 single vessels, n = 4 double 
      vessels) was almost identical (SCABG subset 24.5% versus MIDCAB 23.4%, p = 
      0.860). Slightly more than half (56.9%) of new-onset AFIB subjects were 
      identified by ICD-9 CM codes, with the remainder by word search (37.7%) or 
      procainamide query (5.4%). CONCLUSIONS: In this sample, the number of vessels 
      bypassed seemed to have a greater influence on AFIB prevalence than the 
      application of CPB or the surgical approach. Retrospective identification of AFIB 
      cases by ICD-9 CM code grossly underestimated AFIB prevalence.
