Insights
This rare case details an unusually long left main coronary artery with septal perforators. The coronary arteries were clear of plaques, highlighting a unique anatomical variation.
Area of Science:
- Cardiology
- Human Anatomy
- Medical Imaging
Background:
- The left main coronary artery (LMCA) is a critical vessel supplying blood to the heart.
- Anatomical variations in coronary arteries can impact surgical and diagnostic procedures.
- Septal perforators typically arise distal to the LMCA bifurcation.
Observation:
- A case presenting an exceptionally elongated LMCA measuring 58 mm was identified.
- Multiple septal perforator arteries were observed originating directly from this elongated LMCA, proximal to its bifurcation.
- The remaining coronary arteries were free from atherosclerotic plaques.
Findings:
- The presence of both first and second septal perforator arteries arising from a significantly elongated LMCA is documented.
- This anatomical configuration represents a rare variation in coronary artery branching patterns.
- Absence of coronary artery disease in the observed vessels.
Implications:
- This finding expands the understanding of LMCA anatomical variability.
- Awareness of such variations is crucial for accurate interpretation of cardiac imaging and interventions.
- Further research may explore the clinical significance and prevalence of this rare LMCA anatomy.
Abstract:
We report a case of a very long left main coronary artery (58 mm) with septal perforators before bifurcation. The coronary arteries were seen clear of plaques. To the best of our knowledge, this case is very rare because of the existence of the first and second septal perforator arteries originating from a very long left main coronary artery.

01:21Coronary Circulation
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...

01:15Thoracic Aorta
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,...
01:10The Arch of Aorta
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.

01:18Physiology of the Heart: The Cardiac Cycle
The cardiac cycle describes the events from one heartbeat to the next. It includes three main phases: diastole, atrial systole, and ventricular systole, all driven by changes in chamber pressures and the function of heart valves.
Diastole: The Relaxation Phase
During diastole, all four heart chambers relax. The atrioventricular (AV) valves open, and the semilunar valves close. This phase sees the lowest chamber pressures, promoting ventricular filling. Venous blood enters the heart through the...

01:25Abdominal Aorta
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.

01:14The Aorta
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...
