- 心血管胚胎学 心血管胚胎学
- 诊断成像诊断成像的使用
背景情况:
- 冠状动脉鼻腔 (CS) 是胎儿心脏中的一个关键静脉结构.
- 了解其早期发育和维度变化对于准确的心脏评估至关重要.
- 以前的研究主要集中在较晚的妊娠年龄.
研究的目的:
- 为了比较第一季度 (FT) 和第二季度 (ST) 的冠状动脉鼻 (CS) 的存在,大小和CS与心房比率 (CS/A).
- 调查胎儿生长参数与CS/心房尺寸之间的关系.
主要方法:
- 追溯分析99个胎儿,第一季度 (FT) 的心脏扫描足够,第二季度 (ST) 的心脏正常.
- 通过单个超声波专家测量CS和心房直径.
- 与FT和ST之间的CS/A比率进行比较,并对双对面直径 (BPD) 相对关系进行线性回归分析.
主要成果:
- 在FT (79.2%) 中,CS的可视化频率比ST (43.8%) 更高.
- 与ST (0.25) 相比,FT (0.43) 的CS/A比率显著更高 (P < .0001).
- 在BPD和CS和心房直径之间发现了积极的相关性,心房显示出更快的生长率.
结论:
- 冠状动脉鼻 (CS) 在头三个月 (FT) 与心房相比显得更突出,可能是由于生长速度的差异.

Development of the Heart
903
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...

Development of Blood Vessels
553
The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...

Overview of Systemic Veins
447
Systemic veins are crucial blood vessels that return deoxygenated blood from various body tissues back to the heart. There are three systemic veins that return deoxygenated blood to the heart, they are as follows.
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the...

Fetal Circulation
883
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

Coronary Circulation
2.5K
The heart, an organ critical to survival, gets nourishment not from the blood it pumps but from a separate circulation system known as coronary circulation. This is the shortest circulation in the body and is responsible for supplying the heart with the nutrients it needs to function effectively.
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...

Cardiovascular System Abnormal Findings II: Auscultation
116
Auscultation, an essential part of a heart examination, is done using a stethoscope. It provides crucial information about heart function and possible heart problems. Due to heart problems, abnormal sounds can be heard during systole or diastole. These sounds include S3 and S4 gallops, opening snaps, systolic clicks, and murmurs.
