The Watchman procedure is a one-time, minimally invasive heart implant that reduces
stroke risk in patients with non-valvular atrial fibrillation (AFib) as an alternative to long-
term blood thinners. A parachute-shaped device is inserted via a catheter through the
femoral vein into the heart's left atrial appendage (LAA) to seal it off, preventing clots
from forming and escaping. 

Key Details About the Procedure:
– Purpose: To permanently close off the left atrial appendage (LAA), where 90%
of stroke-causing clots originate in patients with AFib.
– Candidates:
 Individuals with AFib not caused by heart valve issues who need an alternative to blood
thinners due to bleeding risks or intolerance
.
– Procedure Details: Performed under general anesthesia, usually taking 1–2
hours, followed by a one-night hospital stay.
– Recovery: Most patients can return to normal activities within a few days.
– Post-Op Care: Patients typically continue blood thinners for about 45 days until
a follow-up confirms the LAA is completely sealed, after which they may
transition to aspirin only.
