METHODS: An 83-year-old man with a history of syncope was the focus of this case study. An implantable cardiac monitor (ICM) recorded occasional high-degree atrioventricular block in the patient. Subsequently, the Micra AV was implanted via the left femoral vein, and its settings were adjusted in accordance with data obtained from the ICM. No significant issues regarding pacing threshold or impedance were found during the follow-up examinations post-surgery. Importantly, the patient experienced a noticeable reduction in symptoms compared to before the implantation.
CONCLUSIONS: This case underscores the significance of ICM monitoring in elucidating cardiac events leading to syncope and guiding appropriate treatment. It also highlights the successful outcomes and reliable implantation of the Micra AV for managing high-degree atrioventricular block. This study contributes to the growing body of evidence supporting the adoption of leadless pacemakers as a viable option for patients requiring cardiac pacing, particularly those vulnerable to complications associated with traditional pacemakers. It provides real-world evidence of Micra AV\'s efficacy and safety, further validating its role in clinical practice.
方法:本病例研究的重点是一名83岁有晕厥病史的男性。植入式心脏监护仪(ICM)记录了患者偶尔出现的高度房室传导阻滞。随后,通过左股静脉植入Micra房室,并根据从ICM获得的数据调整其设置。在手术后的随访检查中未发现有关起搏阈值或阻抗的重大问题。重要的是,与植入前相比,患者的症状明显减轻。
结论:该病例强调了ICM监测在阐明导致晕厥的心脏事件和指导适当治疗方面的重要性。它还强调了MicraAV治疗高度房室传导阻滞的成功结果和可靠植入。这项研究有助于越来越多的证据支持采用无引线起搏器作为需要心脏起搏的患者的可行选择。特别是那些容易出现与传统起搏器相关的并发症的人。它提供了MicraAV的疗效和安全性的真实证据,进一步验证其在临床实践中的作用。
