The U.S. Food and Drug Administration requires manufacturers to track replacement heart valves and maintain patient records. Before you leave the hospital, the staff will provide you with a temporary patient identification card. This will be replaced with a permanent card once you return home. You should keep this card with you to provide healthcare providers with information about your mechanical heart valve. If you move or your contact information changes, ATS Medical should be notified so records can be updated. You can contact us at 1-763-553-7736. All of the information provided to ATS Medical is kept confidential.
