In early 2020 Food and Drug Administration (FDA) approved Micra AV - a new type of leadless pacemaker with atrioventricular synchrony, to treat patients with atrio-ventricular (AV) blocks. We describe one of the first in Poland case of a patient who was implanted with Micra AV pacemaker.
A 38-year-old female patient was admitted to the clinic due to the 29-seconds event of a complete AV block without an escape rhythm and was implanted with a dual chamber pacemaker without any complications. After several months she was admitted again with suspicion of ventricular perforation by the pacemaker electrode and underwent a replacement procedure of both pacemaker's leads. Nevertheless, one week later the patient developed a fever with significantly elevated inflammatory markers. The blood cultures were negative but in the transesophageal echocardiography features of cardiac device-related infective endocarditis were observed. Empirical antibiotic therapy was administered, and the device was removed. The Heart Team qualified the patient for the implantation of a MicraTM AV leadless pacemaker. The procedure was performed without any complications and the device was implanted to the right ventricle. All parameters were correct, and the patient was discharged.
Micra AV may be a feasible and safe option for young patients with paroxysmal AV block after device-related complications.
描述波兰首例植入 Micra AV 起搏器的患者。
一名 38 岁女性患者因完全性房室传导阻滞伴无逸搏节律的 29 秒事件而就诊，并成功植入双腔起搏器，未出现任何并发症。几个月后，患者因怀疑起搏器电极穿孔再次入院，并进行了起搏器导线更换手术。然而，1 周后，患者出现发热，炎症标志物显著升高。血培养阴性，但经食管超声心动图检查发现与心脏器械相关的感染性心内膜炎的特征。给予经验性抗生素治疗，并移除了器械。心脏团队评估患者适合植入 MicraTM AV 无导线起搏器。手术过程顺利，无并发症，将起搏器植入右心室。所有参数均正常，患者出院。
对于因器械相关并发症而发生阵发性房室传导阻滞的年轻患者，Micra AV 可能是一种可行且安全的选择。
