概括

在TAVR后永久性起器植入可能导致节奏诱导心肌病 (PICM). 本案例报告详细介绍了通过LOT-CRT升级成功治疗PICM的情况,强调了一种新的治疗方法.

科学领域:

心脏病学心脏病学
心脏电生理学心脏电生理学
心脏衰竭管理的管理

背景情况:

过导管大动脉置换 (TAVR) 是对大动脉狭窄的常见手术.
导电障碍是TAVR后的一个已知的并发症,通常需要永久的起器植入.
在TAVR后,特别是使用无心脏起器 (LP) 后,节奏诱导心肌病 (PICM) 的风险和特征仍未得到充分研究.

研究的目的:

描述TAVR后接受无心脏起器 (LP) 的患者患有心脏衰竭的情况,其次是节奏诱导心肌病变 (PICM).
通过使用新型LOT-CRT升级,报告PICM的成功管理.

主要方法:

一个单一患者病例的回顾性审查.
分析了临床表现,诊断工作和治疗过程.
专注于从无节奏调节到带有His捆 (LOT-CRT) 的心脏再同步治疗 (CRT) 系统的过渡.

主要成果:

一名患者在TAVR和LP植入后6个月出现心力衰竭症状.
诊断评估证实了节奏诱导的心肌病.
患者在LOT-CRT升级后显示出显著的临床改善.

结论:

节奏诱导的心肌病是可能的并发症,即使在TAVR之后使用无心脏起器.
在这种特定患者群体中,LOT-CRT升级可以成为PICM的有效治疗策略.
需要进行进一步的研究,以了解无节奏TAVR后PICM的长期影响和发病率.

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Cardiomyopathy V: Interprofessional Care

Cardiomyopathy V: Interprofessional Care

Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...

Cardiomyopathy II: Dilated Cardiomyopathy

Cardiomyopathy II: Dilated Cardiomyopathy

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

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...
