Ahmed Mohsen: Low CHA₂DS₂-VA Score Does Not Always Mean No Anticoagulation

Ahmed Mohsen, Associated Professor of Cardiology at Cairo University, shared a post on LinkedIn:

”AF plus CHA₂DS₂-VA Score – 0… yet I prescribed an Oral Anticoagulant!

Can you identify the reason?

There are several situations where patients with Atrial Fibrillation (AF) require anticoagulation regardless of their CHA₂DS₂-VA score

Hypertrophic Cardiomyopathy (HCM)

  • Fontan circulation
  • Systemic right ventricle
  • Intracardiac cardiac repair in congenital heart disease
  • Cyanotic heart disease
  • After AF ablation (for 8 weeks)
  • After cardioversion (for 4 weeks)
  • Mechanical prosthetic valve
  • Moderate or severe mitral stenosis
  • Other indications for anticoagulation (DVT, PE, LV thrombus, etc.)
  • Thyrotoxicosis (in selected recommendations)
  • Cardiac amyloidosis

Remember: A low CHA₂DS₂-VA score does not always mean no anticoagulation!

From Tips and Tricks in Cardiology.”
