Insights
Dual anterior interventricular artery, a rare congenital heart defect (CHD), was observed in a 15-year-old girl. CT angiography revealed two such arteries originating from the aorta and pulmonary artery.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Vascular Anatomy
Background:
- Congenital heart disease (CHD) encompasses a range of conditions affecting heart structure from birth.
- The anterior interventricular artery, typically arising from the left anterior descending artery, supplies the anterior wall of the left ventricle.
- Variations in coronary artery anatomy are uncommon but clinically significant.
Observation:
- A rare case of dual anterior interventricular artery was identified in a 15-year-old female patient.
- Computed tomography angiography (CTA) was utilized for detailed vascular imaging.
- The CTA revealed two distinct anterior interventricular arteries.
Findings:
- One anterior interventricular artery originated from the aorta.
- A second, anomalous anterior interventricular artery originated from the pulmonary artery.
- This dual origin represents a rare anatomical variation of coronary circulation.
Implications:
- This case highlights the importance of advanced imaging in diagnosing rare CHD.
- Understanding such anatomical variations is crucial for surgical planning and risk assessment.
- Further research into the embryological basis and clinical significance of dual anterior interventricular arteries is warranted.
Abstract:
Dual anterior interventricular artery is a rare type of CHD. We reported a fifteen-year-old girl who underwent CT angiography that demonstrated one anterior interventricular artery from aorta and another from pulmonary artery.

01:16Chambers of the Heart
4.6K
The human heart is a complex organ made up of four chambers: the right and left atria and the right and left ventricles. These internal chambers are separated by partitions known as the interatrial and interventricular septa. The exterior of the heart features a groove known as the coronary sulcus that demarcates the atria from the ventricles, while the anterior and posterior interventricular sulci distinguish between the two ventricles.

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.

01:21Coronary Circulation
2.7K
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.

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...

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
