Pericardial effusion is a condition in which an abnormally large amount of fluid collects in the pericardial sac that surrounds the cat's heart (pericardium). A secondary condition, referred to as cardiac tamponade, results from this retention of fluid, as the swelling of fluid applies pressure on the beating heart, compressing it and restricting its ability to pump blood.
The pressure inside the heart increases, and since the right atrium and ventricles normally have the lowest cardiac filling pressures, they are the most affected by cardiac tamponade. With the elevated pressure inside the cat's heart, the heart has a lower cardiac output, leading to right-sided congestive heart failure. Fluid retention throughout the body typically follows ascites, swelling of the limbs, and weakness or collapse.
Dogs and cats are both susceptible to pericardial effusion. If you would like to learn more about it affects dogs, please visit this page in the PetMD health library.
Your veterinarian will perform a complete physical exam on your cat, including a blood chemical profile, a complete blood count, a urinalysis, and an electrolyte panel, in order to rule out underlying systemic diseases like cancer or infection. You will need to give a thorough history of your cat's health, onset of symptoms, and possible incidents that might have precipitated this condition.
Blood tests can help to diagnose disorder that has caused fluid buildup in the pericardial sac. If infection or cancer is the cause of the pericardial effusion, a pericardial fluid analysis can be done to identify the origin of the cancer, or the type of infection. Radiograph and echocardiograph imaging are crucial for correct diagnosis of pericardial effusion. An echocardiograph is even more sensitive than a radiograph for diagnosis of pericardial effusion. An electrocardiogram, which measures the electrical conductance of the heart, sometimes shows a distinct pattern if the cat is suffering from cardiac tamponade.
If the cat is diagnosed with cardiac tamponade, immediate pericardiocentesis (drawing the fluid out of the pericardial sac with a needle) is essential; however, this is rarely needed in cats.
Cats in respiratory distress will be stabilized with the use of administered oxygen and an oxygen cage. Some animals may need their pericardium surgically removed (pericardiectomy), if there is persistent effusion.
If symptoms of pericardial effusion should reoccur in your cat, contact your veterinarian immediately. If your pet has undergone a pericardiectomy, check the surgical incision every day to make sure it is clean, and that it is healing properly. There is always a risk of infection when the skin has been operated on.
If there is any itching, swelling, redness, or oozing at the surgical site, contact your veterinarian immediately for advisement.
