This Concept Map, created with IHMC CmapTools, has information related to: heart stuff, severe regurgitation elevated systemic venous pressure right heart failure (most commonly ascites in dogs), common heart diseases cats link, Valvular degeneration Tricuspid severe regurgitation, common heart diseases dogs Valvular degeneration, Valvular degeneration Tricuspid mital and tricuspid, mital and tricuspid most common clinical signs Decreased energy Cough Syncope, Cardiomyopathy CS Weight loss (wks) Affected dogs are lethargic, tire easily, breathe rapidly cough frequently sometimes bringing up bloody sputum. ( Coughing is especially common at night.) A swollen abdomen (called ascites) (Cardiac arrhythmias can cause weakness and collapse.), cardiogenic pulmonary edema (ie, left heart failure) chronic chronic increase in left atrial size and pressure can also result in left atrial rupture and acute cardiac tamponade, often resulting in death., Hypertrophic cardiomyopathy (most common) what is it increase in the thickness of the muscular wall of the heart. This reduces the volume of blood within the heart and also prevents the heart muscle relaxing properly between contractions., chronic increase in left atrial size and pressure can also result in left atrial rupture and acute cardiac tamponade, often resulting in death. most common clinical signs Decreased energy Cough Syncope, common heart diseases dogs Cardiomyopathy, elevated left atrial pressure results in elevated pulmonary capillary pressures if the elevation is high enough (ie, ᡌ mm Hg) cardiogenic pulmonary edema (ie, left heart failure), common heart diseases dogs link with cardiac diseases and CS, nodular thickening of the cardiac valve leaflets or cusps, most severely at their tips what does that do? Insufficiency of an atrioventricular (AV) valve results in turbulent, systolic (ie, during ventricular contraction) flow through the affected valve. This regurgitation of blood into an atrium results in an increase in volume within the atrium and thus to an increase in atrial chamber size. When regurgitation is severe, atrial pressure may also increase., Valvular degeneration Mitral elevated left atrial pressure results in elevated pulmonary capillary pressures, right heart failure (most commonly ascites in dogs) most common clinical signs Decreased energy Cough Syncope, increase in the thickness of the muscular wall of the heart. This reduces the volume of blood within the heart and also prevents the heart muscle relaxing properly between contractions. Most common clinical signs Urination/hiding/vomition/behavior Tachypnea/dyspnea Murmur Gallop heart sounds/arrhythmias, common heart diseases cats Hypertrophic cardiomyopathy (most common), Valvular degeneration what is it nodular thickening of the cardiac valve leaflets or cusps, most severely at their tips, Valvular degeneration Mitral mital and tricuspid
