Fetal Circulation01:14

Fetal Circulation

810
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...

Overview of Systemic and Pulmonary Circulation

3.4K
The systemic and pulmonary circuits are crucial components of the circulatory system, working together to transport blood between the heart, lungs, and the rest of the body. The process begins with pulmonary circulation, where deoxygenated blood is pumped from the right ventricle to the lungs via the pulmonary trunk and arteries. Upon reaching the lungs, the blood becomes oxygenated and returns to the heart, specifically to the left atrium, via the pulmonary veins.
The oxygenated blood is sent...

Overview of Pulmonary Circulation

937
The pulmonary circulation is a vital system in our body that acts as a bridge between the respiratory and cardiovascular systems. It serves as a transport network for deoxygenated blood from the heart to the lungs and then returns oxygen-rich blood back to the heart.
The process begins with the right ventricle of the heart pumping deoxygenated blood into the pulmonary trunk. This large vessel extends about 5 centimeters before splitting into the left and right pulmonary arteries. These arteries...

Coronary Circulation01:21

Coronary Circulation

2.3K
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...

Area of Science:

  • Pediatric Cardiology
  • Neonatology
  • Medical Imaging

Background:

  • Systemic-to-pulmonary collateral arteries (SPCA) can cause elevated pulmonary blood flow in neonates.
  • Early detection and monitoring are vital for managing cardiovascular complications in preterm infants.

Purpose of the Study:

  • To report the detection and natural closure of an SPCA in a preterm infant.
  • To highlight the role of echocardiography in managing elevated pulmonary flow.

Main Methods:

  • Echocardiography was used for serial imaging of the infant's cardiovascular system.
  • The SPCA was identified at 18 days of life.
  • Follow-up echocardiography at 11 months confirmed SPCA closure.

Main Results:

  • An SPCA was successfully detected in a preterm infant.
  • The SPCA showed spontaneous closure by 11 months of age.
  • Echocardiography facilitated monitoring of pulmonary blood flow.

Conclusions:

  • Echocardiography is essential for diagnosing and monitoring SPCA in preterm infants.
  • Timely intervention can be guided by regular echocardiographic assessments.
  • Spontaneous closure of SPCA is possible, underscoring the importance of vigilant follow-up.
