This study will investigate CardiaMend, an FDA cleared (K210331) pericardial reconstruction matrix used in combination with amiodarone, an FDA approved antiarrhythmic drug, as a prevention of POAF.~This is a single-center, prospective, pilot study, enrolling adult subjects undergoing isolated cardiac arterial bypass surgery or isolated valve surgery, via complete median sternotomy.~CardiaMend should be used according to the Instructions for Use with the exception that device hydration is performed with 3 ampules of amiodarone (150mg/3ml) instead of room temperature saline. For best results, the device should be fixed in place using a continuous or interrupted stitch (approximately 1 stitch per cm) to approximate the edge of the pericardial defect. The closed defect should not put pressure on the underlying structures. A non-absorbable monofilament suture is preferred such as 5-0 or 4-0 prolene. A small edge may be left open for drain placement and a small slit for LIMA in case of CABG.~Patients will have continuous EKG until discharge. If clinically indicated, patients will receive a monitor for home monitoring per standard of care.
The purpose of this study is to evaluate the combination of CardiaMend, with the addition of amiodarone in the prevention of postoperative atrial fibrillation (POAF) in patients undergoing isolated cardiac arterial bypass grafting (CABG) or valve surgery.
