Class IIb Guidelines
1. Administration of heparin may be considered during the first trimester and last month of pregnancy for patients with AF and risk factors for thromboembolism. Unfractionated heparin may be administered either by continuous intravenous infusion in a dose sufficient to prolong the activated partial thromboplastin time to 1.5 to 2 times the control value or by intermittent subcutaneous injection in a dose of 10 000 to 20 000 units every 12 h, adjusted to prolong the mid-interval (6 h after injection) activated partial thromboplastin time to 1.5 times control. (Level of Evidence: B)

2. Despite the limited data available, subcutaneous administration of low molecular weight heparin may be considered during the first trimester and last month of pregnancy for patients with AF and risk factors for thromboembolism. (Level of Evidence: C)

Administration of an oral anticoagulant may be considered during the second trimester for pregnant patients with AF at high thromboembolic risk. (Level of Evidence: C)

 ACC / AHA 2008 guidelines for diagnosis and management of atrial fibrillation: Class IIb Recommendation 3 for pregnant patients with acute myocardial infarction should be: CLASS I CLASS IIa CLASS IIb CLASS III 4.
