    Sometimes in such a condition the cavity is found dilated. But this condition usually ends in sudden death. The question is raised as to whether such patches are not the result of gummata. [Dr. Fagge gives the following as possible additional causes:— 1. It may result from a primary process of chronic inflammation, a myocarditis, arising in the cardiac mus- cular tissue spontaneously or from rheumatism, or perhaps in consequence of a blow or fall on the chest. 2. The formation of thrombi in the cavities of the heart may give rise to an inflammatory change in the wall of the part of the heart to which they adhere; the ultimate result of this may be the formation of a fibroid patch. 3. Interference with the blood supply of the cardiac wall due to embolism, thrombosis, or atheroma of a branch of the coronary artery. It is probable, however, that syphilis is by far the most usual cause.—Eds.] Congenital Heart Disease. Is believed to arise from intra-uterine disease, not from arrest of development, I. The most common condition is as follows :— a. Before the septum of the ventricle is perfected, endocarditis of the pulmonary valve takes place, and causes various degrees of oblitera- tion of the pulmonary artery. b. The blood being prevented from flowing through the pulmonary artery, will pass from the right ventricle to the left over the top of the incom- plete septum, and will prevent its closure.
