Most cases of<unk>  have been identified postmortem in necropsy. A cross-sectional view of the heart muscle will show a greatly reduced right ventricle size. In necropsy, it is typical for the heart and lungs to be weighed with a higher weight indicating a build up of blood in the lungs: pulmonary congestion. The weight of the lungs is therefore expected to be within normal limits to rule out pulmonary congestion (900-1,280g). The weight of the liver was also part of diagnosis with a significantly greater weight than what is in normal limits (1,440-1,680g) indicative of vein distention. In a clinical setting,<unk>  claims that the presence of isolated right ventricular failure clearly came first with the presence of left ventricular hypertrophy coming secondary indicates the presence of his syndrome. This is especially considered when the heart failure is not due to a weakness in the myocardium but instead stenosis of the myocardial wall. Fluoroscopy to view the blood flow in the heart has also been deemed a reliable tool. It would be expected for the left ventricle and right atrium to be enlarged with the other two chambers appearing "normal". However, it was typical to only confirm the presence of<unk>  in the setting of autopsy.
