Atrioventricular (AV) valve dysplasia is a developmental malformation of the mitral or tricuspid valve in the heart. Signs include exercise intolerance, accumulation of fluid in the abdomen, weight loss, and stunted growth. Difficulty breathing or collapse may occur if congestive heart failure develops. Treatment of AV valve dysplasia is focused on managing signs of congestive heart failure and/or disturbances in heart rhythm, generally using medications.

Endocarditis is an infection of a heart valve, most often affecting the mitral or aortic valve. It can arise any time that bacteria enter the bloodstream, though it is more common when the heart valve has already been damaged for some other reason. The clinical signs of endocarditis are often nonspecific in the early stages, but may progress to include signs of heart failure later in the course of the disease. The diagnosis and treatment of endocarditis can present a challenge, requiring multiple tests and prolonged courses of antibiotic therapy.

Congestive Heart Failure in Dogs
La insuficiencia cardiaca es la incapacidad del corazón para mantener un aporte de sangre suficiente para satisfacer las necesidades del organismo. Una insuficiencia cardiaca suele reflejar un fallo del músculo cardiaco (insuficiencia miocárdica), que puede afectar al ventrículo izquierdo o al derecho.

Aortic stenosis is a heart disease that is present at birth. Cats affected with aortic stenosis have a narrowing at the aortic valve of the heart. The clinical signs of aortic stenosis vary depending on how severe the stenosis is; some cats remain asymptomatic throughout their life, while other cats begin showing clinical signs at an early age and can experience sudden death. The treatment of aortic stenosis depends upon the severity of the condition.

Pulmonary hypertension means that the peak blood pressure in the arteries of the lungs is much higher than normal. Several abnormalities can lead to high blood pressure in the arteries of the lungs and many of the underlying reasons involve the heart. There are many signs of pulmonary hypertension including exercise intolerance, difficulty breathing with or without exertion/exercise, rapid breathing, coughing, spitting up blood from the lungs, fainting, and more. There are many potential causes of pulmonary hypertension. Several medications are available to treat your cat. Activity may need to be restricted. It is essential to monitor cats with pulmonary hypertension for worsening of clinical signs. Periodic physical examinations, blood pressure monitoring, and ultrasound evaluations of the heart are also important. The long-term prognosis is very guarded for cats with pulmonary hypertension.

Though less common than in dogs, some heart conditions in cats are serious and need to be treated medically. The most common type of heart disease in cats is adult-onset hypertrophic cardiomyopathy. The most common types of congenital heart disease are malformations of a valve, or a septal defect in the wall that divides the right and left sides of the heart. Diagnosis involves X-rays, ECG, and echocardiography. Treatment depends on the cause of the heart disease.

This handout discusses what a heart murmur is, how it is detected, what recommended tests are advised to determine the underlying cause, and potential treatments or monitoring that should be undertaken when a murmur is detected in your cat.

Cyanosis is a bluish discoloration of the skin and mucous membranes of the body caused by inadequate oxygen levels. Cyanosis is an emergency, and the root cause may be life-threatening and may or may not be reversible. Once back home, homecare instructions must be followed carefully.

Cardiomyopathy is a term used to describe diseases of the heart muscle. In cats, three classes of cardiomyopathy have been described: hypertrophic, dilated, and intermediate or restrictive cardiomyopathy. In the early stages of disease, the cat may not show any signs. Heart disease can be suspected based on clinical signs, chest X-rays, and electrocardiography (ECG). The long-term prognosis for a cat with cardiomyopathy is variable, and depends on the cause of disease.

Pneumothorax is an accumulation of air outside the lungs, but inside the chest wall. The air outside the lung prevents the lungs from inflating normally, and can lead to lung collapse. There are several variations of pneumothorax.
