A Prospective Study Using Intra-Pericardial Amiodarone for the Prevention of Postoperative Atrial Fibrillation (POAF) in Patients Undergoing Cardiac Arterial Bypass Grafting and/or Valve Surgery

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 cardiac arterial bypass grafting (CABG) or valve surgery.

Detailed Description

This study involves using CardiaMend, an FDA cleared (K210331) pericardial reconstruction matrix with the addition of amiodarone, an FDA approved antiarrhythmic drug, as a prevention of post operative atrial fibrillation. This is a single-center, prospective randomized study enrolling adult subjects undergoing isolated cardiac arterial bypass or valve surgery, via complete median sternotomy. CardiaMend will be used according to the Instructions for Use, and then patted dry to facilitate implantation. Four ampules of amiodarone (150mg/3ml; 12cc total volume) will be drawn into a syringe. 2cc will be dripped over the right atrium and a small CardiaMend patch placed to cover this area. Another 2cc will be used over the left atrium and covered with the CardiaMend. The anterior pericardial space will be closed without putting pressure on the underlying structures using the CardiaMend attached to the native pericardium utilizing running 4-0 monofilament suture. A small edge may be left open for drain placement and a small slit for the Left Internal Mammary Artery (LIMA) in case of CABG. The remaining 8 cc of amiodarone will be instilled to the closed pericardial space. Patients will have continuous electrocardiogram (EKG) until discharge. If clinically indicated, patients will receive a monitor for home monitoring per standard of care.

Inclusion Criteria: - Subject aged 20-85 years old. - Patients able to provide written informed consent, understand, and be willing to comply with study-related procedures. - Participants who are scheduled to undergo open-chest cardiac surgery via complete median sternotomy. Includes: - Coronary artery bypass graft (CABG) and/or valve repair/replacement procedures (aortic, mitral, or tricuspid) - Isolated ascending aortic aneurysm replacement/repair - Note: Left atrial appendage (LAA) procedures are allowed if CABG and/or valve repair or replacement is the qualifying surgical procedure, but is not a qualifying surgical procedure on its own. - In sinus rhythm at the time of office visit and prior electrocardiogram (EKG) (note: continuous EKG monitoring for 48 hours is not required). Exclusion Criteria: - Subject unable to give voluntary written informed consent, is unlikely to cooperate or is legally incompetent, including subjects who are institutionalized by court or official order, or in a dependency relationship with, testing center or investigator. - Any condition which could interfere with the subject's ability to comply with the study. - Ongoing participation in an interventional clinical study or during the preceding 30 days. - Female subjects who are pregnant, breastfeeding, were pregnant within the last three months, or are planning to become pregnant during the course of the study. - Active skin or deep infection at the site of implantation. - History of chronic wounds or wound-healing disorders. - Known connective tissue diseases (e.g. Ehlers-Danlos syndrome, Epidermolysis bullosa, Marfan syndrome, Osteogenesis imperfecta). - Immune-suppressed subjects, immune-deficiency subjects (properly managed diabetes mellitus is not an exclusion criterion). - Concomitant oral or IV systemic corticosteroid therapy and/or other constant anti-inflammatory therapies. - Patients already receiving amiodarone as a treatment for atrial fibrillation or ventricular arrhythmias. - Disease of the left pleura, previous intervention in the left pleural space, or chest deformity. - Subjects with end-stage chronic-renal disease / dialysis. - STS (Society of Thoracic Surgeons Score) risk score >5.5% for 30 day mortality.
