Summary
Anomalous aortic origin of coronary arteries is rare but can cause sudden death or complications during cardiac procedures. Early detection through imaging techniques like echocardiography and CT angiography is crucial for patient management.
Area of Science:
- Cardiovascular Imaging
- Congenital Heart Disease
- Interventional Cardiology
Context:
- Anomalous aortic origin of the coronary arteries (AAOCA) affects 0.02-5.7% of the population.
- AAOCA can lead to sudden cardiac death, especially with interarterial or intramural pathways.
- These anomalies pose risks during interventions on cardiac structures.
Purpose:
- To identify patients with anomalous aortic origin of coronary arteries using imaging modalities.
- To evaluate the effectiveness of transthoracic color Doppler echocardiography (TTE), CT multislice angiography, and coronary angiography in detecting AAOCA.
Summary:
- Fifteen patients with AAOCA were identified.
- Transthoracic color Doppler echocardiography (TTE) raised suspicion in 12 patients; CT multislice angiography was diagnostic in 3.
- The circumflex artery was most frequently involved (12/15), with other cases involving right and anterior descending coronary arteries with interarterial courses.
Impact:
- Underdiagnosis of AAOCA by TTE can occur due to visualization challenges, particularly with age.
- Accurate detection of AAOCA is vital for preventing sudden death.
- Identifying AAOCA is critical for mitigating complications during interventional procedures.

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.

01:21Coronary Circulation
2.9K
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...

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

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.

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,...

The aorta is the largest artery in the human body. It originates from the left ventricle of the heart and extends down to the abdomen, where it splits into two smaller arteries. Structurally, it can be divided into four main parts: the ascending aorta, the aortic arch, the thoracic aorta, and the abdominal aorta.
The average diameter of the aorta is approximately 2-3 cm, but the size can vary depending on the section of the aorta and the individual's age, sex, and body size. The aorta is...
