It is the most common cause of regurgitation in dogs. Other causes of megaesophagus include myasthenia gravis, lead poisoning, and Addison's disease. [143] Gastric dilatation volvulus, commonly known as bloat, is a serious condition in which the stomach swells with air (gastric dilatation), sometimes twisting on itself (volvulus). Deep-chested ...
Pimobendan is indicated for the management of the signs of mild, moderate, or severe congestive heart failure in dogs due to clinical myxomatous mitral valve disease (MMVD) or dilated cardiomyopathy (DCM); [1] [7] and for use with concurrent therapy for congestive heart failure (e.g.,furosemide, etc.) as appropriate on a case-by-case basis.

Aortic regurgitation (AR), also known as aortic insufficiency (AI), is the leaking of the aortic valve of the heart that causes blood to flow in the reverse direction during ventricular diastole, from the aorta into the left ventricle. As a consequence, the cardiac muscle is forced to work harder than normal.
Aortic valve repair or aortic valve reconstruction is the reconstruction of both form and function of a dysfunctional aortic valve. Most frequently it is used for the treatment of aortic regurgitation. [1] It can also become necessary for the treatment of aortic aneurysm, less frequently for congenital aortic stenosis.
Just like aortic stenosis, treatment for aortic regurgitation is replacement of the valve after symptoms and left ventricular dysfunction develops. SUMMARY All right, as a quick recap…. Aortic stenosis happens if the aortic valve doesn’t open all the way, and aortic valve regurgitation happens if the valve doesn’t close all the way.
Aortic valve replacement is a cardiac surgery procedure whereby a failing aortic valve is replaced with an artificial heart valve. The aortic valve may need to be replaced because of aortic regurgitation (back flow), or if the valve is narrowed by stenosis .
Canine subvalvular aortic stenosis (SAS) is an abnormal, congenital heart murmur caused by subaortic stenosis (SAS). This genetic trait is polygenic , and in some cases asymptomatic. An animal with SAS may offspring and show no symptoms of the stenosis until multiple generations which is why it is advised not to breed an animal diagnosed with SAS.
Treatment of an infected dog is difficult, involving an attempt to poison the healthy worm with arsenic compounds without killing the weakened dog, and may not succeed. Prevention is recommended via the use of heartworm prophylactics , which contain a compound that kills the larvae immediately upon infection without harming the dog.
