Core Tip
Core tip: Patients with mechanical prosthetic cardiac valves require life long systemic anticoagulation. Maintaining therapeutic anticoagulation consistently is challenging, given the variable dose requirements with warfarin, especially with dietary changes and drug interactions. We present a case of a patient with fluctuating control of anticoagulation, which led to an unusually large horseshoe thrombus in her left atrium and subsequent cerebrovascular complications. We also provide a review of literature, diagnostic modalities and treatment options.
