Study Title: Surgical Ablation Versus No Surgical Ablation for Patients with Persistent or Longstanding Persistent Atrial Fibrillation Undergoing Mitral Valve Surgery

Current Status: Enrollment Complete.

Study overview

The purpose of the research is to determine whether surgical atrial fibrillation ablation performed during scheduled mitral valve surgery (surgery to repair a heart valve, a part of the heart which helps control the flow of blood) is better than mitral valve surgery by itself without the surgical ablation. Surgical ablation of atrial fibrillation is a technique used by surgeons to create scars in atrial heart tissue that block electrical signals that may be causing the heart to beat irregularly. People who have mitral valve disease requiring surgery and atrial fibrillation may take part in this research study.

Study Title: Surgical Interventions for Moderate Ischemic Mitral Regurgitation

Current Status: Enrollment Complete.

Study Overview

The purpose of the research is to determine whether repairing a mitral valve (a heart valve which helps control the flow of blood) with moderate leakage (regurgitation), at the time of planned coronary artery bypass graft (CABG) surgery, will improve health outcomes of those who receive it compared to those who have the bypass alone. People who have coronary artery heart disease, requiring a CABG surgery, and have leakage (regurgitation) of the mitral valve may take part in this research study.

Study Title: Evaluation of Outcomes Following Mitral Valve Repair/Replacement in Severe Chronic Ischemic Mitral Regurgitation

Current Status: Enrollment Complete

Study Overview

The purpose of this research is to determine whether it is better to repair or replace the mitral valve (a heart valve which helps control the flow of blood) of patients with severe mitral valve leakage (regurgitation) from coronary artery disease. People who have mitral valve leakage (regurgitation), which may be severe, may take part in this research study.

Study Title: RATE CONTROL VERSUS RHYTHM CONTROL FOR POSTOPERATIVE ATRIAL FIBRILLATION

Current Status: Open to Enrollment

Study Overview

The purpose of the research is to compare two strategies for treating atrial fibrillation or atrial flutter, both of which are referred to as AF, after cardiac surgery. AF is when the upper chambers of your heart (atria) experiences disorganized electrical activity which causes your heart beat to be irregular. AF is the most common complication after cardiac surgery. The two treatment strategies to be used in this study are called rhythm control and rate control. The rhythm control strategy will attempt to bring your heart beat back to a regular rhythm using treatments known and approved to control heart rhythm. The rate control strategy will attempt to bring your heart rate to less than 100 beats per minute at rest using medications known and approved to control heart rate. Both strategies are commonly used to treat AF. This research seeks to determine whether rhythm control is better than rate control in patients with AF after cardiac surgery. People who are undergoing cardiac surgery to treat coronary artery disease (a narrowing of the small blood vessels that supply blood and oxygen to the heart), and possibly a disease of one or more of your heart valves may take part in this research study.
