New Procedure Can Replace Coumadin in Some Patients with Atrial Fibrillation
North Memorial Health cardiologists will soon offer an innovative one-time procedure that reduces the risk of stroke in non-valvular atrial fibrillation (NVAF) patients who are unable to tolerate long-term warfarin use.
The WATCHMANâ„¢ Implant closes off the left atrial appendage (LAA), preventing blood clots from migrating out of it. The LAA is where over 90 percent of stroke-causing clots originate in patients with atrial fibrillation.
Candidates for the WATCHMANâ„¢ Implant:
- Have non-valvular atrial fibrillation
- Have increased risk for stroke (CHADS > 2 or CHDS2Vasc > 3)
- Are suitable for short-term warfarin use (about 45 days post-procedure)
- Have an appropriate reason to seek a non-pharmacologic alternative to warfarin (high fall risk, recurrent bleeds, etc.).
The hour-long procedure will be performed under general anesthesia in the North Memorial Catheterization Lab. Patients typically stay in the hospital overnight.
