Beebe Healthcare’s cardiovascular team was the first in Delaware or Maryland to utilize the WATCHMAN FLX Pro implant Feb. 7. The WATCHMAN FLX Pro is a left atrial appendage closure device used to treat patients who have been diagnosed with non-valvular atrial fibrillation. Also known as AFib, this heart rhythm disorder increases risk for stroke and requires that many patients rely on anticoagulation medications long-term.
