- 干预心脏病学 干预心脏病学
- 结构性心脏病 结构性心脏病
- 心脏外科手术 心脏外科手术
背景情况:
- 额头环状化 (MAC) 对退行性额头回 (DMR) 中的跨导管干预提出了重大挑战.
- 小额门孔区域 (MVOA) 进一步复杂化了MAC的DMR的治疗选择.
研究的目的:
- 报告第一个 mitra transcatheter 边缘到边缘修复 (TEER) 的病例,该病例发生在患有严重的 DMR,严重的 MAC 和轻微的 MVOA 的患者身上.
- 突出了在TEER期间管理MAC相关挑战的新"步行"技术的实用性.
主要方法:
- 一名患有严重的DMR,严重的MAC和3.8厘米2的MVOA的患者使用爱德华兹帕斯卡系统进行了TEER.
- "行走"技术,涉及独立的小册子扣操作,被用来解决MAC相关的困难.

242
Mitral regurgitation (MR) is characterized by retrograde blood circulation from the left ventricle into the left atrium due to inadequate mitral valve closure. The severity of the condition, symptoms, and underlying cause determine treatment strategies.Monitoring and Pharmacological TreatmentPatients with mild to moderate MR typically do not need immediate intervention but regular monitoring to assess progression and guide treatment. Patients with mild MR should have an echocardiogram every 3-5...

215
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. Timely...
