概括
通过导管更换大动脉之后的传染性内心炎可能会导致危险的上升大动脉虚动脉瘤. 心脏CT对于诊断这种罕见的并发症至关重要,经常被心声回声学遗漏.
科学领域:
- 心脏病学 心脏病学
- 传染性疾病 传染性疾病
- 心血管外科心血管外科
背景情况:
- 通过导管大动脉置换 (TAVR) 后的传染性内心炎 (IE) 是一种不常见但严重的并发症.
- 术后TAVRIE与手术门置换后内心炎相比,可能会带来独特的挑战.
研究的目的:
- 描述患有传染性内心炎的患者在TAVR后因感染上升性大动脉假动脉瘤而复杂的特征和结果.
- 要突出心脏计算机断层扫描 (CT) 在这些情况下的诊断实用性.
主要方法:
- 在2016年1月至2024年10月期间,向第三级心脏中心转诊的TAVR后IE患者的回顾性评估.
- 分析临床数据,成像发现 (特别是心脏CT) 和治疗策略.
主要成果:
- 60名患者中有7名 (11.7%) 患有TAVR后IE,患有假动脉瘤和主动脉炎,主要与自我扩张的透导管心脏 (THV) 相关.
- 在THV稳定弧度形成的假动脉瘤,通常需要手术干预,包括门扩张器和大动脉修复或更换.
- 心脏CT对诊断至关重要,而心声回声扫描对检测这些特定并发症的敏感性较低.
结论:
- 术后TAVRIE可能导致危及生命的上升性大动脉虚动脉瘤,与外科膜内心炎不同.
- 早期怀疑和先进的成像,特别是心脏CT,对于准确的诊断和管理计划至关重要.

Endocarditis II: Clinical Features of Infective Endocarditis
542
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests
559
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

False Memories
485
False memories represent a cognitive distortion in which individuals recall events that did not happen, or remember them in an altered form. This phenomenon highlights the brain's constructive nature in processing and recalling memories, emphasizing that memory is not a perfect representation of past events but rather a dynamic reconstruction influenced by various factors.
One primary source of false memories is misattribution, where individuals incorrectly associate external information...

Endocarditis I: Introduction
518
Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...

The Aorta
3.0K
The aorta is the largest artery in the human body. It originates from the left ventricle of the heart and extends down to the abdomen, where it splits into two smaller arteries. Structurally, it can be divided into four main parts: the ascending aorta, the aortic arch, the thoracic aorta, and the abdominal aorta.
The average diameter of the aorta is approximately 2-3 cm, but the size can vary depending on the section of the aorta and the individual's age, sex, and body size. The aorta is...
