As hospitalists, we focus on the stroke risk, and we find that the ACC/AHA guidelines do not recommend bridging for this patient’s type of aortic valve. Either is an acceptable form of bridging anticoagulation for patients at intermediate or high risk of thromboembolism, but for patients with low thromboembolism risk, the potential bleeding complications of bridging outweigh the possible thromboembolism prevention.
