概括
在低可塑性左心综合征 (HLHS) 中,剩余的左心室 (LV) 不会随着时间的推移显著影响右心室 (RV) 功能或大小. 这一发现是基于连续的心血管磁共振 (CMR) 随访.

- 儿童心脏病学 儿童心脏病学
- 遗传性心脏病研究 遗传性心脏病研究
- 心血管成像 - 心血管成像
背景情况:
- 缺血性左心综合征 (HLHS) 是一种复杂的先天性心脏缺陷.
- 以前的研究表明,左心室 (LV) 的扩大对HLHS患者的右心室 (RV) 功能有潜在的负面影响.
- 在HLHS中LV残留的临床意义需要进一步调查.
研究的目的:
- 评估LV残留物对VR大小和功能在HLHS患者的影响.
- 用心血管磁共振 (CMR) 来分析RV和LV参数的连续变化.
- 为了确定LV残留物的存在是否会影响长期RV性能.
主要方法:
- 在全腔肺连接后的HLHS患者中,对连续CMR检查的回顾性分析.
- 患者被分为具有和没有LV残留的组.
- 测量RV和LV体积,中风体积,射出分数 (RVEF,LVEF) 和终端透气质量.
主要成果:
- 包括90名至少两次CMR扫描的HLHS患者;56人有LV残留物.
- 索引RV体积和质量,以及RVEF,在组之间没有显著差异.

Mitral Stenosis I: Introduction
423
Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...

Mitral Regurgitation I: Introduction
394
Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...

Development of the Heart
2.0K
The development of the human heart, a crucial organ, commences from the mesoderm on the 18th or 19th day after fertilization. This process initiates in the cardiogenic area, a group of mesodermal cells at the embryo's head end, which evolves into elongated strands known as cardiogenic cords. These cords undergo a transformation to form hollow-centered endocardial tubes.
As the embryo undergoes lateral folding, these paired tubes approach each other, merging into a single primitive heart...

Heart Failure II: Pathophysiology
695
Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...
