Summary
A rare solitary coronary ostium anomaly, with the left anterior descending artery anterior to the pulmonary artery, is presented. Cardiac computed tomography (CCT) aided in precise anatomical visualization.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Medical Imaging
Background:
- Coronary anomalies are uncommon cardiovascular conditions.
- A solitary coronary ostium without other congenital defects is exceptionally rare.
- Accurate anatomical depiction of coronary anomalies can be challenging with standard angiography.
Observation:
- A case report details a patient presenting with acute myocardial infarction.
- Coronary angiography revealed a single coronary ostium arising from the right sinus of Valsalva.
- The left anterior descending artery coursed ventral to the pulmonary artery, and the circumflex artery ran retroaortically.
Findings:
- This specific coronary anomaly, though theoretically described, is unprecedented in clinical reporting.
- Cardiac computed tomography (CCT) provided superior 3D visualization of the complex coronary anatomy.
- CCT demonstrated added value over conventional coronary angiography for detailed anatomical assessment.
Implications:
- This case expands the understanding of rare coronary artery anomalies.
- Highlights the diagnostic utility of CCT in complex congenital coronary variations.
- Emphasizes the importance of advanced imaging for surgical and interventional planning.

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...

01:22Mitral Stenosis I: Introduction
Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...
01:20Mitral Regurgitation I: Introduction
Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...
01:15Aortic Regurgitation I: Introduction
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...
01:16Chambers of the Heart
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.

01:16Heart Valves
The human heart is a complex organ with an intricate system of valves that regulate blood flow. There are two main types of valves: atrioventricular (AV) valves and semilunar valves.
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
