A peritoneopericardial diaphragmatic hernia is an irregular gap between the abdomen and the membrane that surrounds the heart. It typically develops as a congenital defect in dogs. A diaphragmatic hernia can be described as an abnormal hole in the membrane that divides the abdomen and the chest cavity. This results in an opening through which the organs located in the abdomen can extend up into the chest. The most commonly herniated organs are the liver, followed by the small intestine, spleen, and stomach. Most cases have different symptoms, with the defect not showing up in patients affected until after they are dead. Chest x-rays or special contrast x-rays can be used to see whether the intestine or liver has protruded past the membrane and into the pericardium (the sac enveloping the heart. Echocardiography can also be used to diagnose the condition. Good candidates for surgical repair of the hernia are dogs with signs such as vomiting, hepatic encephalopathy (build-up of toxic substances in the brain), or other unpleasant conditions ensuing from the hernia.
Cor Triatriatum Dexter
Cor Triatriatum Dexter is a heart condition that affects dogs, and is the result of a fibrous membrane separating the right atrium into two halves, or two chambers. The membrane that divides the two chambers usually has one or more perforations, allowing communication to take place between the two parts of the atrium. Surgical treatment is the most effective option for this particular condition.
