◽️doesn’t inactivate functional clotting factors
◽️prothrombin half life: 72h
◽️Ergo INR effect 24-36 hr
🛑 teratogenic
For "Valvular afib": Warfarin & LMWH
◽️rheumatic MS
◽️mechanical or mitral valve
◽️mitral valve repair

◽️💊 interactions
◽️BMI ⚖️
◽️ pharmacokinetic profiles vary 👇

NOAC advantages:
◽️lower bleeding risk
◽️no lab monitoring 💉
◽️not dependent on vit K

Warfarin advantages:
◽️ok in renal impairment
◽️easily reversable

@mirvatalasnag @venkmurthy @fischman_david @DrToniyaSingh @DrMarthaGulati @VietHeartPA @Regadenoson
LA appendage: source of embolization and thrombus formation due to:
◽️intense fibrosis and inflammation
◽️pectinate muscle

Consider for:
◽️↓plts, coagulopathy
◽️recurrent bleeding
◽️intolerance of AC
◽️high risk or prior falls

@cardiojaydoc02 @mark_kaeppler
Various ways to exclude the LAA👇

◽️WATCHMAN (preferred @HopkinsMedicine)
◽️AMPLATZER Cardiac Plug
◽️Surgical removal
