Patients undergoing WATCHMAN device Implantation

You may qualify if:

  • Age ≥18 years, and
  • CHADS2 ≥1 and/or CHADS-VASc ≥2, and
  • Prior major bleeding (intracranial, gastrointestinal bleeding, intraocular, respiratory, genitourinary, retroperitoneal, pericardial, anemia requiring transfusions, etc.), or contraindications to long-term OAC (HASBLED ≥3, high fall risk, cerebral aneurysm, blood dyscrasias, aortic dissection, etc.), or failure of OAC (stroke/TIA while on OAC)
