Dr. Dunnington is the principle investigator in The Stroke Feasibility Study at St. Helena:

The Stroke Feasibility Study, launched by AtriCure, will assess the safety and effectiveness of the AtriClip Left Atrial Appendage Exclusion System in reducing strokes in afib patients who are unable to take anticoagulants.

The AtriClip is applied to the left atrial appendage of the heart during a minimally invasive surgical procedure. The left atrial appendage is the source of more than 90 percent of afib-related blood clots. The Stroke Feasibility Study will determine the effectiveness of the AtriClip in reducing strokes in patients with non-valvular atrial fibrillation.

Learn more about the AtriClip and the Stroke Feasibility Study.
