概括

在无支架门中,门内透导管大动脉植入 (ViV-TAVI) 是具有挑战性的. 由于并发症风险增加,仔细选择患者至关重要,尽管结果可以被接受.

科学领域:

心血管医学心血管医学
干预心脏病学干预心脏病学
心脏外科手术心脏外科手术

背景情况:

过导管大动脉植入 (TAVI) 是外科置换的一种不那么侵入性的替代方案.
门内TAVI (ViV-TAVI) 是需要重复主动脉手术的患者的一个选择.
无支架门中的ViV-TAVI与支架门相比,存在独特的挑战.

研究的目的:

为了评估ViV-TAVI的结果,特别是在先前植入无支架的大动脉的患者中.
确定与这种具有挑战性的ViV-TAVI程序子集相关的潜在并发症和成功率.

主要方法:

在2018年1月至2023年12月期间,对15名在无支架门中接受ViV-TAVI治疗的患者进行了回顾性分析.
主要终点:30天和随访死亡率.
二级终点:门学术研究联盟 (VARC) -3技术成功,设备成功和早期安全.

主要成果:

该研究包括15名患者 (平均年龄为78.1岁),中位数STS-PROM为4.30.
常见的症状是严重的大动脉吐 (53.3%) 和狭窄 (33.3%).
30天死亡率为6.7% (1名患者),平均随访2.9年期间有4例死亡. 在VARC-3的技术成功率为87.6%,设备成功率为80%,早期安全率为73.3%.

结论:

无支架门中的ViV-TAVI与程序风险增加有关,需要对患者进行细致的选择.
尽管面临挑战,但可以实现可接受的技术和早期安全结果.
需要进行更大规模的研究来验证这些发现,并完善患者选择标准.

Mitral Stenosis III: Medical Management

Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage.
