Atrial Fibrillation Management for Cataract Surgery
Preoperative Assessment and Anticoagulation
- The European Society of Cardiology recommends calculating the CHA₂DS₂-VASc score to determine thromboembolic risk, with males having scores ≥2 or females having scores ≥3 requiring anticoagulation regardless of surgical timing 1, 2
- The American Heart Association suggests assessing current anticoagulation status and ensuring therapeutic dosing, as well as evaluating for hemodynamic stability and adequate rate control 1, 2
Perioperative Anticoagulation Management
- The American College of Cardiology recommends continuing anticoagulation without interruption for cataract surgery, as it is classified as a low-bleeding-risk procedure where the benefits of continued anticoagulation outweigh bleeding risks 1, 2
- For patients on DOACs, the European Heart Journal suggests continuing therapy through the perioperative period without interruption 1, 2
- For patients on warfarin, the American Heart Association recommends maintaining an INR of 2.0-3.0 3, 4
Rate Control Optimization
- The European Society of Cardiology recommends continuing beta-blockers throughout the perioperative period in all patients without contraindication, as withdrawal increases the risk of perioperative atrial fibrillation 1, 2
- The American College of Cardiology suggests using alternative agents, such as diltiazem or verapamil, if LVEF >40% and beta-blockers are contraindicated 1, 2
Postoperative Management
- The American Heart Association recommends maintaining the same anticoagulation strategy postoperatively, continuing anticoagulation indefinitely based on CHA₂DS₂-VASc score, regardless of whether the patient remains in sinus rhythm 1, 2, 5
Risk Factor Optimization
- The European Society of Cardiology suggests optimizing modifiable bleeding risk factors, including controlling hypertension, avoiding NSAIDs perioperatively, correcting any anemia, and not using bleeding risk scores to withhold anticoagulation 1, 2
