[Malformations of the heart and endocardiosis in swine].

The authors describe in 321 of 170,000 examined slaughter pigs certain cardiac malformations which were associated with endocardiosis of the mitral valve. Aortic stenosis was associated with endocardiosis of the aortic valve. It is assumed that in certain breeds of swine a congenital predisposition for impairment of the collagen metabolism may support the development of endocardiosis.
