The effect of open-chest cardiac resuscitation on mitral regurgitant flow: an on-line transesophageal echocardiographic study in dogs.

Introduction: We sought to determine the effect of cardiac massage on a pre-existing regurgitant mitral valve during open-chest cardiopulmonary resuscitation (OCCPR) in an animal experiment.

Methods: Our study included 29 dogs that were used as experimental models. We anesthetized them and inserted a transesophageal echocardiographic (TEE) probe.

Multiple cardiac metastases from a malignant melanoma.

Metastatic tumors in the pericardium or the heart are more common than primary tumors and their incidence has increased during the last decades due to the prolonged survival of patients with cancer and the increased prevalence of the disease in the general population. We present the case of a 36-year-old patient admitted to our hospital due to fatigue, dyspnea, and episodes of dizziness and fainting during the last month. He had a history of a malignant skin melanoma surgically removed 4 years ago.

One-year follow-up of a patient with reversible tricuspid valve stenosis due to lymphomatic mass into the right atrioventricular wall.

We present the case of a 66-year-old man with a history of coronary artery disease and chronic lymphocytic leukemia (CLL) who was admitted to the hospital complaining of chest discomfort and shortness of breath on exertion. The echocardiogram revealed a severe pericardial effusion and a large echogenic mass that infiltrated the lateral wall of the right atrium and ventricle and created a moderate tricuspid valve stenosis. B cell intracardiac non-Hodgkin lymphoma/CLL was diagnosed, and the patient was treated with six courses of CHOP chemotherapy.

Follow-Up of an Unresectable Hemangioma in the Heart.

We present the case of a patient with a hemangioma, a benign heart tumor, that is revealed incidentally during cardiac catheterization. The patient had coexisting coronary artery disease. This rare tumor remained unchanged in size, and the patient has been asymptomatic for a period of 20 years.
