Persistence of the oval hole foramen ovale persistence after birth is located in interarterial septum and favors the mixing papilloma inner eyelid the arterial with venous papilloma inner eyelid eventually causing death by hypoxia.
In the structure of all valves, especially in the atrioventricular ones, can be found congenital hematic cyst with the diameter to an inch. Pericardium injuries Dystrophic lesions of the pericardium is of less importance in mammals, while in birds they produce irreversible changes sometimes incompatible with life.
Serous atrophy of the pericardium occurs in older animals, in the chronic wasting disease. papilloma inner eyelid
