title: Heartworm disease in dogs: unusual clinical cases.
abstract: Two unusual cases of heartworm infection are described, including one of spontaneous rupture of cardiac chambers, most likely due to the progressive increase in pressure within the right ventricle caused by Dirofilaria immitis infection. Another case report describes persistent left cranial vena cava, which interfered with the surgical removal of heartworm via the left jugular vein.
