If your veterinarian has suggested a total pericardiectomy, it is because your dog’s heart is not pumping blood through their body efficiently or effectively and other treatments have failed. Your veterinarian will have already drained the excess fluids or prescribed medications to improve the heart’s functionality.
If your dog has been diagnosed with cancer and has metastatic tumors in the area, the heart sac could swell. The prognosis may not be good for dogs with cancer, and the total pericardiectomy will only aid in treating the symptoms of cancer by ridding the heart and sac of tumors. However, cancer may remain, and additional treatment will be necessary.
However, if your veterinarian has recommended a total pericardiectomy as a result of an idiopathic effusion, the chances of your dog’s survival after removing the recurring swelling of the pericardium are high. A total pericardiectomy would improve your dog’s overall health, and a healthy dog should be able to return to a normal life with regular activity once recovery is complete.
