atrial fibrillation ablation
Surgical or catheter-based procedure to eliminate abnormal electrical pathways causing atrial fibrillation.
Full Definition
Atrial fibrillation ablation involves creating strategic lesions in atrial tissue to interrupt the abnormal electrical circuits responsible for atrial fibrillation. The procedure can be performed using radiofrequency energy, cryotherapy, or surgical techniques during open-heart surgery. The goal is to restore normal sinus rhythm and reduce stroke risk associated with atrial fibrillation. Anesthetic considerations include managing anticoagulation, potential for air embolism during left atrial access, and hemodynamic changes associated with rhythm conversion. Post-procedural monitoring focuses on rhythm stability and early detection of complications.
Usage
Usage note: May be abbreviated as AF ablation; distinguish from other cardiac ablation procedures.
