A physiologic murmur is quite common in cats.   This is usually the result of a dynamic right ventricular outflow tract obstruction (dRVO).   This condition is created when the muscle of the right ventricular outflow tract squeezes and narrows the exit to the right...

Pulmonary arterial hypertension is a state of high blood pressure within the lung (pulmonary) circulation.   This condition can be due to heartworm disease and embolic disease (clots into the lungs); however, some cases are considered idiopathic (cause unknown).  ...

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, which increases oxygen demands and can cause changes to the myocytes (muscle cells).   In veterinary medicine, this...

An aortic thromboembolism is a blood clot that has developed within the heart.   It typically lodges at the distal aorta, often termed a “saddle thrombus”, which supplies the rear limbs with blood.   This condition makes the affected limbs painful, cold to touch, and...

Restrictive Cardiomyopathy is a primary myocardial disease wherein the heart muscle is damaged. The myocardium becomes infiltrated with fibrous scar tissue that prevents normal function (failure of both squeezing and relaxation).   This is a non-curable and...

Dilated Cardiomyopathy is a primary myocardial disease wherein the heart muscle is damaged and becomes very weak.   In cats, this is usually idiopathic, but can develop secondary to nutritional deficiencies (specifically Taurine deficiency).   The left ventricle...
