概括

先天性心脏缺陷 (CHD) 与胎盘问题有关. 小胎盘和婴儿出生小的妊娠年龄 (SGA) 是更常见的怀孕与胎儿心脏病,表明胎盘功能受损.

科学领域:

周围生理学周围生理学
胎儿医学胎儿医学
心脏病学心脏病学

背景情况:

先天性心脏缺陷 (CHD) 是最常见的先天性形.
被诊断患有心血管疾病的胎儿具有较高的风险,比妊娠年龄小 (SGA),这表明胎盘功能受损.
在孤立的心脏病怀孕中,研究胎儿心脏发育和胎盘健康之间的相互作用至关重要.

研究的目的:

为了检查胎儿心脏异常和胎盘特征之间的关系,在怀孕中复杂的孤立的CHD.
确定特定类型的冠状动脉疾病是否与特定的胎盘发现或胎儿生长限制有关.

主要方法:

在高等推中心进行了一项回顾性队列研究.
确定了2009年至2020年期间怀疑胎儿心血管疾病的单独怀孕.
确认的心血管疾病病例被分类,并分析了出生体重,胎盘体重和出生体重/胎盘体重比例.

主要成果:

这项研究分析了302个被证实患有心血管疾病的胎儿.
在孤立的冠状动脉疾病病例中观察到SGA新生儿 (20.4%) 和小胎盘 (低于第10百分位,28.4%) 的显著发病率.
特定的冠状动脉疾病类型,如单和左侧病变,显示出更高的胎盘异常率.

结论:

胎儿心血管疾病的怀孕表明,小胎盘,SGA和孕前的患病率增加.
改变胎儿心脏-胎盘血动力学可能导致胎盘发育受损,导致胎儿生长受限.
在受胎儿心脏病影响的怀孕中,建议加强对胎盘功能障碍和胎儿生长的监测.

Fetal Circulation

Fetal Circulation

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...

Imbalances in Cardiac Output

Imbalances in Cardiac Output

The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...

Teratogenicity

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
