This study is testing a tool called the CardioGard Embolic Protection Cannula to see if it helps during heart valve surgeries. A cannula is a tube used to move fluids in or out of the body. This study will check if the CardioGard is better than the usual cannula. People will be randomly chosen to either try the new cannula or stick with the usual one. The study lasts 30 months, and patients will be followed for a year after surgery.

To join, you must be at least 60 years old and having specific heart valve surgeries. You can’t join if you’ve had a stroke recently or have certain other health issues. If you join, you might also be part of a smaller study checking if sleep affects recovery.

• The study will take place in the U.S. and Canada and lasts up to 30 months.
• Patients will be monitored for 12 months after surgery.
• A smaller study will look at how sleep patterns affect healing.
