Heart failure and congestive heart failure are medical syndromes in which a dog exhibits signs related to a complex interaction between a failing heart and the blood vessels. In heart failure, the blood flow is insufficient to supply organs with enough oxygenated blood for proper function. Depending on the degree of severity, signs of heart ...

It is not uncommon for young puppies, especially large breed dogs, to develop an innocent heart murmur. The murmur may first appear at 6 to 8 weeks of age, and usually goes away by age 4 to 5 months. This type of murmur is benign. A heart murmur that does not fit the criteria of seven S’s (see box) should be considered pathologic. A heart murmur th...
Generally, all murmurs in adult dogs are indicative of structural heart disease. The cause of a murmur can often be determined or strongly suspected based on auscultation and the signalment of the patient. Left apical systolic heart murmurs:Left apical systolic heart murmurs indicate mitral regurgitation. The most common cause of mitral regurgitati...
Kittens can also have innocent flow heart murmurs. It is important not to squeeze the chest too hard which might create a murmur. As with puppies, a heart murmur that is grade III or higher, continuous, still present at 6 months, heard best on the right, or that it is getting worse should be evaluated.
A new onset of heart murmur in adult cats should be evaluated. Left sided systolic heart murmur is the most common. Hypertrophic cardiomyopathy (HCM) is the most likely cause; other possibilities include other cardiomyopathy and a physiologic heart murmur caused by dynamic right ventricular outflow tract obstruction (DRVOTO).
Should all heart murmurs undergo comprehensive evaluation? Not necessarily. It requires consideration of the animal’s use. In some cases, sufficient information can be obtained from the physical examination to educate clients and provide guidance without further evaluation. On the other hand, breeding animals should be screened more aggressively fo...
Murmur intensity is a poor index of the severity of mitral regurgitation in dogs, except in the case of a soft (grades 1–2) murmur. A soft murmur is almost always associated with mild mitral regurgitation. However, a loud murmur is not necessarily associated with severe disease or left heart failure.
Congestive heart failure (left-sided) in dogs is known as subaortic stenosis (SAS). This condition distresses the heart’s left side, with the opening in the middle of the left ventricle and an aorta that is too narrow, resulting in the harder, overworked left ventricle forcing the blood through this abnormally narrow area to flow into the aorta.

Apr 6, 2018 · In dogs and cats, the fluid is retained in specific parts of the body, depending on the side of the heart that is diseased. If the left side of the heart is diseased (e.g. mitral valve disease, most dilated cardiomyopathies , hypertrophic cardiomyopathy, and most common congenital cardiac defects), fluid is mostly retained in the lungs or within the pleural cavity (the chest space around the ...
