概括

血管内透症 (IVL) 在跨导管大动脉置换 (TAVR) 之前,在复杂的双主动脉 (BAV) 中有效地改变了. 这种新的方法改善了假肢扩张和患者的结果,解决了化BAV TAVR中的挑战.

科学领域:

心脏病学心脏病学
干预心脏病学干预心脏病学
医疗器械医疗器械

背景情况:

对于双主动脉 (BAVs),特别是那些严重化的人,通过导管的大动脉置换 (TAVR) 面临着挑战.
这些挑战包括假肢不充分膨胀和膜泄漏,影响手术成功和患者的治疗结果.

研究的目的:

提出一个案例,证明了 intravascular lithotripsy (IVL) 在 TAVR 之前在严重化的 BAV 中进行修饰的新型用途.
突出IVL在复杂的BAV解剖学中促进TAVR的潜力.

主要方法:

一名70岁的男性患者患有严重的大动脉狭窄和严重化的Sievers-0 BAV,呈现出心力衰竭和慢性病.
血管内透术 (IVL) 用于修饰,随后进行气球膜整形和部署26毫米的Evolut PRO+ TAVR假肢.
评估了临床结果,包括假肢扩张和准膜泄漏.

主要成果:

患者在TAVR后经历了很好的临床康复.
没有观察到对膜泄漏,心室功能得到改善.
在复杂的化BAV解剖学中,IVL促进了假肢的最佳扩张.

结论:

血管内透症 (IVL) 是一种可行的选择,用于在经过TAVR的严重化的BAV中进行病变准备.
IVL可以控制骨折,增强门合规性,并可能减少TAVR并发症.
开发用于结构性心脏干预的专用IVL设备是一个尚未满足的需求.

Mitral Stenosis III: Medical Management

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.
