The investigators are presently using Exparel, a slow released local anesthestic, in patients
undergoing minimally invasive cardiac surgery. The primary objective of this study is to
assess the efficacy of EXPAREL when delivered into the thoracotomy and chest tube sites to
provide prolonged postoperative analgesia in patients undergoing minimally invasive cardiac
surgery. Efficacy will be assessed by: the effectiveness of analgesia as measured by the
subject's overall postoperative pain scores and postsurgical analgesic use.
