概括

过导管大动脉置换 (TAVR) 后的救助失败 (FTR) 在高死亡率的中心更高. 改善FTR可以减少TAVR后死亡率的差异,并改善患者的治疗结果.

科学领域:

心血管医学心血管医学
医疗保健服务研究医疗服务研究

背景情况:

跨导管大动脉置换 (TAVR) 的结果在医疗机构之间有很大差异.
无法救援 (FTR),即无法预防并发症后的死亡,是这种变化的潜在驱动因素.

研究的目的:

调查医院特定的FTR率与TAVR后死亡率之间的关联.
确定改善TAVR过程和患者结果的机会.

主要方法:

从STS/ACCTVT注册表 (2011-2016) 中分析了61,804例输性TAVR病例.
使用观察到预期的手术死亡率比率计算医院FTR率.
多变量后勤回归以评估FTR与医院死亡率的关联.

主要成果:

在高死亡率 (5.6%) 的医院,TAVR后的死亡率明显高于低死亡率 (1.8%) 的医院.
风险调整后的并发症率在医院死亡率三分之一之间显示出极小的差异.
调整后的FTR率在高和中死亡率的医院 (14.6%和9.5%) 与低死亡率的中心 (5.4%) 相比明显更差.
在高死亡率中心观察到更高的FTR率,包括转换为开放手术,中风和心脏骤停等并发症.

结论:

跨中心存在TAVR死亡率的显著差异,并不能完全通过并发症率来解释.
在高死亡率中心的患者,由于FTR,死亡风险不成比例地增加.
专注于TAVR后的护理过程对于解决FTR和减少死亡率变化至关重要.

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...

Aortic Regurgitation I: Introduction

Aortic Regurgitation I: Introduction

IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

Aortic Regurgitation IV: Nursing Management

Aortic Regurgitation IV: Nursing Management

A nurse managing a patient with aortic regurgitation begins with a comprehensive assessment, including a review of the patient's medical history, family history, and lifestyle factors. During the cardiac examination, the nurse listens for heart sounds and checks for signs of valve abnormalities. The nurse also observes for symptoms such as dyspnea, orthopnea, and paroxysmal nocturnal dyspnea and assesses the patient's endurance and daily activity tolerance.Based on the findings, the nurse...
