AtriCure Enrolls First Patient in Randomized Multi-Center Trial Evaluating Post-Operative Afib
This study will evaluate the effects of excluding the LAA in cardiac surgery patients at high risk of developing post-operative Afib
Postoperative Afib occurs in up to 30% of patients undergoing cardiac surgery.(1) Research has shown that specific risk factors predict patients at greatest risk.(2) POAF is associated with increased complications, increased reoperations and longer hospital length of stay.(3) The ATLAS study will compare the clinical impact of patients at highest risk of developing POAF to two randomized treatment arms: surgical left atrial appendage (LAA) exclusion (using AtriClip LAA Exclusion Systems) and patients with POAF and no surgical LAA exclusion. In addition, the study will evaluate healthcare resource utilization between the two groups.
“This is a very important study that will help us evaluate how left atrial appendage management can improve care for cardiac surgery patients,” said Michael Carrel, President and Chief Executive Officer of AtriCure. “Studies have shown that the incidence of POAF in patients undergoing cardiac surgery remains high in spite of numerous attempts to drive this complication of surgery down. This study will help us determine if a better care path exists for these at-risk patients with the ultimate goal of improving patient care and decreasing healthcare costs.(1)”
This observational study will evaluate the thromboembolic and hemorrhagic events of subjects diagnosed with POAF (AtriClip vs. no AtriClip) through 365 days post index procedure. The study will enroll up to 2,000 patients at 20 sites who are scheduled for cardiac surgery with specific risk factors for developing new onset POAF as well as significant risk factors for bleeding on commonly prescribed medications to decrease the risk of Afib-related stroke.
“Clinical equipoise exists between effective LAA exclusion at the time
of cardiac surgery vs prophylactic anti-coagulation of POAF in patients
at elevated risk of major bleeding.” said Dr. Basel Ramlawi, Chairman
Heart and Vascular Center,
"It is an honor and privilege for our team at Pinnacle to be part of
this highly important trial and enroll the first patient,” said
