Mitral valve repair is an open heart procedure to treat narrowing or leakage of the mitral valve. The mitral valve is the inflow valve for the left side of the heart. Blood flows from the lungs, where it picks up oxygen, and into the heart through the mitral valve. When open, the mitral valve permits oxygenated blood to flow into the heart's main pumping chamber called the left ventricle.

A pacemaker is basically made up of two parts - a generator and the leads. The pacemaker generator constantly monitors your heart for the electrical signals, which keep the heart beating. If a signal is not found within the programmed amount of time (specified by your doctor) the pacemaker will send an electrical impulse to make your heart beat. The generator also houses the pacemaker's battery, which in normal circumstances needs to be replaced every 3-6 years.

This is a procedure which uses radio waves to silence an abnormal area in the heart's electrical system, which is usually found during an electrophysiology study.
