概括

本案例研究展示了一种新的技术,用于防止冠状动脉阻塞在跨导管大动脉置换 (TAVR) 期间. 生物假体或本地大动脉贝故意撕裂以防止阳性冠状动脉阻塞 (BASILICA) 技术成功修改了四大动脉.

科学领域:

干预心脏病学干预心脏病学
结构性心脏病是什么
心脏外科手术心脏外科手术

背景情况:

冠状动脉阻塞是通过导管的大动脉置换 (TAVR) 的罕见但严重并发症.
四柱动脉由于改变了解剖结构,为TAVR带来了独特的挑战.
可能需要修改说明书以防止冠状动脉阻塞.

研究的目的:

描述使用生物假体或本地大动脉贝故意撕裂以防止在TAVR之前患有四柱性大动脉的患者中预防Iatrogenic冠状动脉阻塞 (BASILICA) 技术的可行性和结果.
在TAVR手术过程中展示一种用于管理复杂的大动脉解剖学的新方法.

主要方法:

一名38岁的男性患者因四柱主动脉引起严重的主动脉吐,接受了手术前分析.
生物假体或本地大动脉贝故意撕裂以防止阳性冠状动脉阻塞 (BASILICA) 技术用于双片修改,将本地门转换为六片片.
随后进行了透气管大动脉置换 (TAVR).

主要成果:

在TAVR之前,使用BASILICA技术进行了双重传单修改,并成功完成了.
患者很好地忍受了联合手术,干预后症状明显改善.
随访的胸前回声图证实了生物假体大动脉的正常功能,没有冠状动脉阻塞的迹象.

结论:

在TAVR之前,BASILICA技术是复杂的大动脉解剖学,如四门等复杂的大动脉修改的可行选择.
完整的手术前规划和先进的手术内成像指导对于成功应用这种技术至关重要.
这种方法可以有效地预防阴性冠状动脉阻塞,并在具有挑战性的病例中允许成功的TAVR.

Aortic Regurgitation III: Medical Management

Aortic Regurgitation III: Medical Management

Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...
