Summary
The Dogue de Bordeaux breed shows a high prevalence of aortic stenosis, characterized by a smaller aortic annulus and decreased aortoseptal angle. These findings suggest a breed predisposition to this cardiac condition.
Area of Science:
- Veterinary Cardiology
- Canine Health
- Cardiac Imaging
Background:
- Aortic stenosis is a significant cardiac condition in dogs.
- Understanding breed-specific predispositions is crucial for early detection.
Purpose of the Study:
- To determine the occurrence of aortic stenosis in Dogue de Bordeaux dogs in Denmark.
- To establish echocardiographic reference values for this breed.
Main Methods:
- Fifty-three Dogue de Bordeaux dogs underwent cardiac auscultation and echocardiography.
- Aortic stenosis was diagnosed by a peak aortic velocity exceeding 2.5 m/s via subcostal view.
Main Results:
- A cardiac murmur was detected in 72% of dogs.
- Aortic stenosis was identified in 17% of the dogs.
- Dogue de Bordeaux exhibited a smaller aortic annulus and decreased aortoseptal angle compared to normal values.
Conclusions:
- The Dogue de Bordeaux breed appears highly predisposed to aortic stenosis.
- A small aortic annulus and reduced aortoseptal angle may be key etiological factors.

01:22Aortic Regurgitation II: Clinical Features and Diagnostic Tests
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...
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...
01:14The 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...

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...
01:30Aneurysm I: Introduction
An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...
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,...
