Complications of any mechanical prosthesis include thrombus or pannus formation. In our case report we demonstrate that prosthetic aortic valve regurgitation due to pannus formation may be intermittent and non-cyclic in pattern and therefore not obvious at the time of original clinical examination. Under these conditions and as transesophageal echocardiography cannot be repeated promptly, transthoracic 2-D and Doppler echocardiography should be available at any time when symptoms occur and present the method of choice for acute patient evaluation. Thrombolysis seems to be the first treatment of choice in case of thrombus formation and re-do surgery in case of pannus formation.
任何机械假体的并发症都包括血栓或血管翳形成。在我们的病例报告中，我们证明了由于血管翳形成导致的人工主动脉瓣反流可能是间歇性的且无周期性模式，因此在最初的临床检查时并不明显。在这些情况下，由于不能及时重复经食管超声心动图检查，当出现症状时，应随时进行经胸二维和多普勒超声心动图检查，这是急性患者评估的首选方法。对于血栓形成，溶栓似乎是首选的治疗方法；对于血管翳形成，则需再次手术。
