Charcteristic pathological finding in carcinoid hea disease is:
When there is cardiac involvement of the carcinoid syndrome it can lead to endocardial fibrosis (mainly right ventricle), pulmonic and tricuspid valve thickening. Ref: Robbin's Basic Pathology, 7th Edition, Page 587; Harrison's Principles of Internal Medicine, 16th Edition, Page 1413.
Fibrous endocardial thickening of Right ventricle, Tricuspid valve & Pulmonary valve
Endocardial thickening of Tricuspid valve with severe Tricuspid Stenosis
Collagen rich, elastic deposits in endocardium of right ventricle and Pulmonary valve
