Indications for percutaneous left atrial appendage closure (LAAC). OAC: oral anticoagulation
| Primary indication for percutaneous LAAC |
| Elevated thromboembolic risk (CHA2DS2-VASC > 3) |
| Contraindicated for long-term OAC |
| Potential indications for percutaneous LAAC |
High risk of bleeding with OAC due to:
|
| Presence of thromboembolic phenomena while on therapeutic OAC |
| Chronic OAC intolerance (ie, severe gastrointestinal disease) |
| Employed in high-risk occupations |
| Unwilling to take or comply with OAC |
