Helios Cardio Inc.80 enrolled

Overview

The goal of this clinical trial is to is to test the safety of a new way to deliver a commonly used drug (amiodarone) used in heart surgery by placing a patch containing the drug directly on the heart instead of in an IV (vein). Participating subjects must be 20-85 year old males or females. Up to 80 participants having cardiac surgery at the University of Louisville will be involved in this study. The main questions this study aims to answer are: 1. Is the patch safe? 2. Does the patch lower the rate of atrial fibrillation (irregular heart rhythm) after cardiac surgery? Researchers will compare up to 3 different doses of the amiodarone patches (low, medium and high) to the usual treatment (Standard of Care) to see if there are differences (increases or decreases) in heart rhythms after cardiac surgery across study groups. Participants will be placed in one of 4 study groups: * Standard of Care (20 participants) * Low dose patch (20 participants) * Medium dose patch (20 participants) * High dose patch (20 participants) Participants will be monitored closely by their doctor(s) during the study and would: * Agree to participate after having their doctor, or a member of the team, explain the study in detail and allowing them to ask any questions they would like. * Sign an Informed Consent Form which will describe the study and tests in full. * Agree to have their doctor and his/her research team record your medical information, draw blood, and perform electrocardiograms, or EKGs (quick, painless test that measures the electrical activity of the heart) and echocardiograms (image of heart) to monitor their heart. * Agree to receive training on the portable EKG recorder and to use it at home approximately 30 days and 6 months after their surgery to monitor their heart. * Agree to return to the hospital approximately 30 days and 6 months after their surgery for a study visit. Participant involvement will be approximately 7 months total.

The purpose of this study is to determine the safety of a drug-device treatment for the prevention of postoperative atrial fibrillation following open heart surgery. Approximately a quarter of patients will develop atrial fibrillation after open heart surgery. Atrial fibrillation is a type of irregular heart rhythm or arrhythmia, in which the heart does not pump effectively. This can lead to problems such as stroke, palpitations (an abnormal heart rhythm that can feel like your heart is racing or pounding) and prolonged hospital stays. The goal of this study is to determine if the application of a medication (amiodarone) containing patch on the surface of the heart at the time of surgery is safe, which may lead to a treatment to lower the rate of atrial fibrillation in patients undergoing open heart surgery. The study drug-device is not yet FDA approved.
