Core Tip
Core tip: Thromboembolism represents an important complication following heart valve replacement. This case report shows that although vitamin K antagonist (VKA) treatment represents the elective therapy in patients with left atrial thrombosis without mitral valve dysfunction, it may not be sufficient to avoid thrombogenesis. We also recommend that the discontinuation of VKA during the first three months after mitral valve surgery has to be carefully considered, especially in high thromboembolic risk patients.
