Anomalous left coronary artery in a calf
Journal of the American Veterinary Medical Association
|September 1, 1978
Insights
A rare congenital heart defect, anomalous left coronary artery from the pulmonary artery, was found in a calf. This condition caused endocardial fibrosis and mitral valve issues, impacting the heart's function.
Area of Science:
- Veterinary Cardiology
- Congenital Heart Disease
- Comparative Pathology
Background:
- Congenital heart anomalies are critical in veterinary medicine, affecting animal health and welfare.
- The coronary arteries supply blood to the heart muscle; abnormalities can lead to severe cardiac dysfunction.
- Anomalous origin of the coronary arteries is a recognized, though uncommon, group of congenital defects.
Observation:
- A 4-month-old Hereford calf presented with a unique cardiac abnormality.
- The left coronary artery originated abnormally from the pulmonary artery.
- The right coronary artery exhibited a typical origin from the aorta.
Findings:
- Histopathological examination revealed endocardial fibrosis in the left atrium and left ventricle.
- The mitral valve was observed to be dilated and thickened, indicative of valvular pathology.
- The anomalous coronary artery origin is the primary suspected cause of the observed cardiac changes.
Implications:
- This case highlights the importance of recognizing and diagnosing congenital coronary artery anomalies in veterinary patients.
- Understanding such anomalies aids in comparative cardiology research between species.
- Early diagnosis and management strategies for similar conditions can improve outcomes in affected animals.
Abstract:
An anomalous left coronary artery was seen arising from an ostium in the pulmonary artery in a 4-month-old Hereford calf. Endocardial fibrosis was found in the left atrium and left ventricle. The mitral valve was dilated and thickened. A normal right coronary artery originated from the aorta.

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,...
01:25Abdominal 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.

01:12Arteries of the Upper Limbs
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...
01:20Arteries of Lower Limbs
The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular artery,...

Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...
