Anita Rayner, Associate Policy Director, FDA: In the cardiovascular area, FDA (Food and Drug Administration) recently approved a pacemaker that can treat some of the symptoms of moderate-to-severe congestive heart failure. In some heart failure patients, the left and right ventricles don't contract simultaneously as they should. This device corrects that condition by providing specially-timed electrical impulses to the ventricles. It's called the "InSync Biventricular Cardiac Pacing System", and it's made by Medtronic Inc. of Minneapolis. The system includes a pulse generator implanted in the patient's chest, which is connected to three lead wires that deliver the electrical impulses. One lead goes to the right atrium, the other two are placed in each of the ventricles, where they stimulate those chambers to beat simultaneously. Even though this device may relieve some of the symptoms of congestive heart failure, it's not been shown to be useful in all heart failure patients. It should be used only in patients with moderate-to-severe symptoms of congestive heart failure whose ventricles are not contracting simultaneously and aren't likely to improve with additional drug therapy. And it shouldn't be used in patients whose congestive heart failure is reversible.
