Variability exists regarding the timing and duration of anticoagulation after surgical ablation for atrial fibrillation and bioprosthetic mitral valve replacement (MVR). We report a case in which a patient developed a massive left atrial (LA) thrombus after MVR and left-sided radiofrequency ablation (LRFA). Despite acutely elevated gradients across the bioprosthetic valve, the patient remained asymptomatic and hemodynamically stable; thus, a multidisciplinary, patient-centered discussion was had and the patient was treated successfully with oral anticoagulation.
关于房颤外科消融和生物瓣二尖瓣置换（MVR）后抗凝的时机和持续时间存在差异。我们报告了一例 MVR 和左侧射频消融（LRFA）后患者发生左心房（LA）巨大血栓的病例。尽管生物瓣跨瓣压差急剧升高，但患者仍无症状且血流动力学稳定；因此，进行了多学科、以患者为中心的讨论，并成功地采用口服抗凝治疗对患者进行了治疗。
