Pericardial Reconstruction May Help Control Atrial Fibrillation after Coronary Bypass

In Atrial fibrillation (AFib)

By: James Pitt  Aug. 09, 2018

Atrial fibrillation (Afib) is a major risk of coronary bypass surgery (CABG). Incidence estimates vary greatly depending on study methodology, from 5 to 40% of patients. Among 49,264 patients who underwent CABG from 2001-2012 in the Society of Thoracic Surgeons database, 19% had new-onset atrial fibrillation.

Pericardial reconstruction is a promising technique for preventing atrial fibrillation after CABG. In a retrospective study of 222 patients, Boyd et. al (2010) concluded that pericardial reconstruction with an extracellular matrix (ECM) implant reduced the relative risk of Afib by 54%.

To examine the need for atrial fibrillation prevention after CABG, Dexur analysts examined atrial fibrillation incidence in CABG patients; and atrial fibrillation readmission rates after CABG. The sample included Medicare-eligible inpatients at 23 Ohio hospitals from 2013-2016.

The highest incidence of Afib in CABG patients was 43.94%, at The Christ Hospital (Cincinnati, OH). The lowest incidence was 21.71%, at Springfield Regional Medical Center. Note that these incidence rates include patients who had AFib before the procedure.

The highest 30-day readmission rate was at Trinity Medical Center West (Steubenville, OH), where 15.04% of CABG discharges were readmitted with atrial fibrillation within 30 days. The lowest 30-day atrial fibrillation readmission rate was 3.97%, at Aultman Hospital (Canton, OH).
