Summary
Coronary artery anomalies, such as an ectopic left circumflex artery, can be associated with atherosclerosis. Early detection during coronary angiography is crucial for appropriate treatment and management.
Area of Science:
- Cardiology
- Anatomical Variations
- Interventional Cardiology
Background:
- The left circumflex artery (LCx) typically arises from the left coronary sinus.
- Anatomic variations of the LCx are common, but arising as a proximal branch of the right coronary artery (RCA) is rare.
- Coronary artery anomalies can be associated with atherosclerotic disease.
Observation:
- Two cases of ectopic left circumflex coronary artery are presented.
- Case 1: A 64-year-old male with risk factors for cardiovascular disease presented with chest pain and had an ectopic LCx from the right coronary sinus with stenosis in the RCA and LCx.
- Case 2: A 67-year-old male with hypertension and diabetes presented with chest pain and had an ectopic LCx from the proximal RCA with stenosis in the LAD, RCA, and LCx.
Findings:
- Coronary angiography revealed ectopic left circumflex coronary artery in both patients.
- Both patients had coexisting atherosclerotic coronary artery disease requiring intervention.
- Patients successfully underwent revascularization procedures based on established guidelines.
Implications:
- Coronary artery anomalies should be considered during coronary angiography, especially in cases of atherosclerotic disease.
- Recognition of these variations is essential for accurate diagnosis and treatment planning.
- Anomalous coronary artery origins may influence the development and presentation of coronary atherosclerosis.

01:21Coronary Circulation
8.7K
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.

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.

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,...

01:14The Aorta
3.8K
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...

The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...
