概括

心脏窒息是一种罕见的副心脏起器植入的并发症,可以在几年后发生. 心肌输液成像检测出由于心脏起器线压缩而引起的显著缺血,导致成功的再植入.

科学领域:

心脏病学心脏病学
儿童心脏病学儿童心脏病学
医疗成像医学成像

背景情况:

心脏窒息是儿童上心脏起器植入后的罕见但严重的并发症.
它是由节奏电线对心脏结构的压缩造成的,可能导致缺血.
这一案例突出了心脏窒息的延迟呈现,植入后八年.

研究的目的:

报告一例罕见的儿科患者延迟心脏窒息的病例.
为了说明心肌输液成像 (MPI) 在评估心脏起器线压缩的功能意义上的实用性.
强调在长期的起器随访中考虑延迟并发症的重要性.

主要方法:

一份病例报告详细介绍了一名患有心上节拍器植入史的儿科患者.
计算机断层扫描血管造影 (CTA) 用于确定左前下降动脉 (LAD) 的外部压缩.
进行心肌输液成像 (MPI),以评估受影响冠状动脉区域的诱导性缺血症.

主要成果:

计算机断层扫描血管学揭示了心上节奏线对左前下降动脉 (LAD) 的显著外部压缩.
心肌输液成像显示,LAD区域内存在大量可诱导性缺血,表明功能性损害.
患者接受了成功的心脏起器再植入,以缓解压缩.

结论:

用心上节拍器电线进行心脏窒息可能在植入后几年出现.
心肌输液成像是功能性评估心脏起器诱导的冠状动脉压缩的宝贵工具,即使在无症状患者中也是如此.
及时诊断和干预,包括节拍器修复,对于管理这种罕见的并发症至关重要.

Blood Studies for Cardiovascular System I: Cardiac Biomarkers

Blood Studies for Cardiovascular System I: Cardiac Biomarkers

Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...

Acute Coronary Syndrome III: Diagnostic Studies

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

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,...
