Summary
A rare coronary artery variant, a "split" right coronary artery (RCA) with a "split" posterior descending artery, was incidentally found in an 87-year-old man. This finding highlights the importance of recognizing anatomical variations during imaging.
Area of Science:
- Cardiovascular Imaging
- Anatomical Variations
- Radiology
Background:
- Coronary artery anomalies are uncommon but significant findings in cardiovascular imaging.
- Accurate identification of coronary artery variants is crucial for interpreting diagnostic scans and surgical planning.
Observation:
- Coronary CT angiography in an 87-year-old male incidentally revealed a unique anatomical variation.
- The right coronary artery (RCA) exhibited a distinct "split" morphology.
- Further examination showed the posterior descending artery also presented a "split" feature.
Findings:
- The observed anomaly is characterized as a "split" right coronary artery (RCA) with a "split" posterior descending artery.
- Morphological details of this rare variant were documented.
- Key differentiations were made between this "split" RCA and other anomalies like "dual" or "duplicated" RCA.
Implications:
- Recognition of this "split" RCA variant is essential for radiologists and cardiologists.
- Understanding such anomalies aids in avoiding misinterpretation during coronary CT angiography.
- This case contributes to the literature on coronary artery anatomical variations.

01:21Coronary Circulation
3.0K
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...

01:10The Arch of Aorta
771
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.

01:15Thoracic 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,...

01:25Abdominal 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.

01:18Physiology of the Heart: The Cardiac Cycle
3.0K
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...
