Left Atrial Appendage Occlusion (LAAO) – CHA₂DS₂-VASc / HAS-BLED Hybrid Index Enter patient data. Use 1 = yes / 0 = no for binary fields. Age is in years; Sex is M or F.
LAAO CHA₂DS₂-VASc / HAS-BLED Hybrid Index: Explanation and Clinical Context This calculator combines stroke and bleeding risk scores to guide consideration of left atrial appendage occlusion (LAAO). Patients with high CHA₂DS₂-VASc (≥2 in men, ≥3 in women) and high HAS-BLED (≥3) are typical candidates for LAAO, especially when oral anticoagulation (OAC) poses excessive bleeding risk. The tool supports decision-making but does not replace clinical judgment.
Final decisions should integrate patient preferences, anatomy, and contraindications.
