Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is being done to learn the effects of the Pulmonary Vein Isolation in patients that are at high risk to developing, but do not have a documented history of atrial fibrillation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients with a dilated left atrium (left upper chamber of the heart) that undergo mitral valve surgery may be at risk for the development of atrial fibrillation after surgery.

Atrial fibrillation (also known as "A-Fib" or AF) is an abnormal heart rhythm which may cause symptoms such as pounding sensations in your chest, dizziness, fatigue, chest pain and/or shortness of breath. AF patients are at a higher risk of developing a stroke.

Participants who sign informed consent will be randomized into one of two groups by chance (as in the flip of a coin).

Approximately 77 patients will undergo their mitral valve operation along with Pulmonary Vein Isolation (a treatment group) and 77 patients who do not undergo Pulmonary Vein Isolation at the time of their mitral valve surgery (a control group).

The treatment group will undergo operation for mitral valve disease with an additional procedure called Pulmonary Vein Isolation using a device that delivers radiofrequency energy to the heart muscle in order to create scar tissue to block electrical impulses that can trigger episodes of AF.

The control group of patients will undergo operation for mitral valve disease without the additional Pulmonary Vein Isolation.
