Acquired Heart Disease

Physiologic Murmur in Dogs

A physiologic murmur is common in large-breed dogs.   This represents mild turbulence within the great vessels and is not the result of structural heart

Systemic Hypertension in Dogs

Systemic Hypertension is a state of high blood pressure within the body. This means that the heart must work very hard to propel blood forward,

Heart Base Tumors in Dogs

Heart Base Tumors are most frequently chemodectomas, which are benign, slow growing tumors of the aortic body chemoreceptors.   These tumors can cause the accumulation

Right Auricular Mass in Dogs

A right atrial/auricular mass is most likely a hemangiosarcoma.   Other tumor types would include chemodectoma or carcinoma.   The prognosis is typically poor; however,

Pericardial Effusion in Dogs

Pericardial Effusion is a condition where there is a fluid accumulation within the pericardial sac.   This causes the pressures outside of the heart to

Dilated Cardiomyopathy in Dogs

Dilated Cardiomyopathy is a primary myocardial disease wherein the heart muscle is damaged and becomes very weak.   The left ventricle dilates and has a

Chronic Valve Disease in Dogs

Myxomatous Mitral Valve Degeneration (i.e. Chronic Valve Disease or Endocardiosis) is a chronic, degenerative disease of the mitral valve (62% of affected patients have only

Sick Sinus Syndrome (SSS) in Dogs

Sick Sinus Syndrome (SSS) is a condition where the sinus node (normal pacemaker of the heart) is diseased and not responding normally to the body’s

Ventricular Premature Complexes in Dogs

Ventricular Premature Complexes or Ventricular Tachycardia is an electrical disturbance, where the ventricular myocardium depolarizes at incorrect times. These may be due to numerous etiologies,

Atrial Premature Complexes in Dogs

Atrial premature complexes are often the result of atrial dilation (left or right); however, additional considerations would be mechanical irritation (perihilar lymph node enlargement, atrial/auricular

Atrial Fibrillation in Dogs

Atrial fibrillation is a condition where the atrium (top chambers of the heart) are no longer allowing organized electrical activity.   Rather, there is a
