Tumors of the heart and pericardium

Abstract Among 1,082 cases of malignant disease appearing in a series of 11,100 consecutive post-mortem examinations performed at the Cleveland City Hospital during the past twenty years, the heart, including the pericardium, was involved by metastatic tumor in 118 cases, an incidence of 10.9 per cent. Carcinoma of the bronchus and the breast most often invaded the heart and pericardium and accounted for 48 per cent of the cases in this series. The development of congestive failure without other apparent cause, in a patient with malignant disease, was the most important clinical finding pointing to cardiac metastasis.

Catheterization of the Left Side of the Heart in Man

The technic employed in catheterization of the left heart in man is described. A catheter is introduced into the left ulnar artery and passed through the brachial, axillary and subclavian arteries into the arch of the aorta. With the tip of the catheter at the root of the aorta, we have succeeded in entering the left ventricle only in patients with free aortic insufficiency due to syphilis. Failure to pass the aortic valves in normal subjects is discussed.

Cor pulmonale: Observations in fifty autopsy cases

Abstract The observations made in this series of cases entirely support the conclusions of older clinicians and pathologists regarding the relation between chronic emphysema and failure of the right side of the heart. The clinical course and autopsy observations indicate that the right ventricle is burdened in emphysema, presumably by an elevation in pulmonary pressure, and that it undergoes dilatation and hypertrophy and ultimately fails. That increased pulmonary pressure burdens the right ventricle and leads ultimately to death from heart failure is shown clearly by two cases in this series in which an aneurysm at the root of the aorta compressed the main pulmonary artery. In the majority of cases the left ventricle also was hypertrophic, but the cause of this hypertrophy was not apparent. It is suggested that the anatomic relation of the two ventricles is so intimate that hypertrophy of one chamber ultimately involves the other.

Dissecting aneurysm of aorta with hemorrhagic infarction of the spinal cord and complete paraplegia

Abstract A case of dissecting aneurysm of the aorta is presented in which all the intercostal arteries were severed, causing hemorrhagic infarction of the spinal cord and complete motor and sensory paraplegia. To our knowledge it is the first such case reported in which spinal subarachnoid hemorrhage occurred.

Stokes-Adams Attacks Induced by Rectal Stimulation in a Patient with Complete Heart Block

This paper reports a case of complete heart block whose Stokes-Adams attacks were induced by straining at stool and invariably by digital stimulation of the rectum. Electrocardiograms during attacks exhibited high ventricular tachycardia or fibrillation and chaotic heart action.

An improved method for visualizing the coronary arteries at post mortem

Abstract A technique for visualizing the coronary bed of the heart has been described which has certain advantages over previously described methods. It is simple and the entire procedure requires only two hours. The method of dissection preserves the cardiac valves, and the injection mass, which is color fast, does not distort the histologic picture of the myocardium.
