Study Purpose: This study looks at how video game-based exercises can help people recover better after open heart surgery. The focus is on improving lung function and independence in daily activities.

The second group will also do video game exercises with "Breathing Labs Breathing Games" in the hospital and Xbox games at home. Exercises are twice daily in the hospital and three times a week after discharge. Tests will be done before surgery and after 12 weeks to measure changes in strength, activity, and quality of life.
