Summary
This study details two congenital heart malformations featuring common arterial trunk and pulmonary atresia. Autopsy revealed specific anatomical details of the great arteries and associated pulmonary hypoplasia.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Pathology
Background:
- Congenital heart defects represent a significant cause of mortality and morbidity.
- Common arterial trunk (CAT) and pulmonary atresia are rare but severe cardiac malformations.
Purpose of the Study:
- To describe the detailed pathological findings in two cases of congenital heart malformation with common arterial trunk and pulmonary atresia.
Main Methods:
- Autopsy examination of two hearts with congenital malformations.
- Detailed gross pathological description and dissection of cardiac structures.
Main Results:
- Both cases presented with common arterial trunk and pulmonary atresia, usual atrial arrangement, and concordant atrioventricular connections.
- Variations in the origin of the common arterial trunk from the ventricles were noted.
- Hypoplastic but patent pulmonary arteries originated from the common trunk, with a dimple near the atretic segment.
Conclusions:
- Congenital heart malformations with common arterial trunk and pulmonary atresia exhibit specific anatomical variations.
- Detailed pathological examination is crucial for understanding these complex defects.

01:19Overview of Pulmonary Circulation
973
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...

01:15Thoracic Aorta
396
The thoracic section of the aorta begins at the T5 vertebra and extends to the T12 level at the diaphragm, initially progressing through the mediastinum to the left of the spinal column. Throughout its course in the thoracic segment, the thoracic aorta emits various offshoots known collectively as visceral and parietal branches. The branches that predominantly supply blood to visceral organs are termed visceral branches and include bronchial, pericardial, esophageal, and mediastinal arteries,...

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...

01:15Overview of Systemic and Pulmonary Circulation
3.5K
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.

01:21Coronary 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...

Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.
