Twee gevallen van peritoneopericardiale hernia diafragmatica bij de kat

Peritoneopericardial diaphragmatic hernia (PPDH) is a common incidental finding in cats during echocardiography or at thoracic radiographs. Two cases of PPDH in cats with clinical signs are discussed. The first cat was presented with inspiratory dyspnea secondary to herniation of omentum, pylorus, liver and gallbladder within the pericardial space. The presentation of the second case was more exceptional. The cat was presented with intermittent tachycardia. During the surgical correction of the PPDH, the myocardium of the left ventricle was damaged. The cat was euthanized. Histopathologic results of the heart, diaphragm and liver showed that the epicard and the capsule of the liver could not be differentiated and formed a tightly connective tissue layer
