RESUMO
The case of a 62-year-old diabetic and smoker male who was under study in another hospital due to anemia, thrombopenia and hematuria of several months of evolution is presented. The patient was admitted to the coronary unit for an acute extensive transmural myocardial infarction and treated with t-PA. A few hours later the patient presented hematuric urine, a decrease in hemoglobin and platelets and acute renal insufficiency. Hematologic study confirmed the diagnosis of paroxystic nocturnal hemoglobinuria. The evolution of the patient was poor despite intensive medical treatment requiring hemodialysis. The patient presented cardiac tamponade and died. The role of hematologic disease in acute myocardial infarction and the treatment and evolution of the coronary syndrome in the context of the disease are discussed.

Transesophageal echocardiography is a semi-invasive diagnostic technique with a very low incidence of significant complications. Only two deaths related to the procedure have been reported in the literature. We present the case of a 46-year-old man with a right atrial mass, presumably a cardiac myxoma. During attempts at esophageal intubation for a transesophageal echocardiography procedure, the mass fragmented and dislodged, causing massive pulmonary embolism and death. We believe that to avoid this potential complication, great care must be taken in the evaluation of patients with a right intracardiac mass by means of transesophageal echocardiography.

A 56 year-old woman with rheumatoid arthritis was diagnosed with idiopathic dilated cardiomyopathy. She developed progressive heart failure that was refractory to conventional medical management. Heart transplantation was performed bearing in mind the controversy that surrounds its use in patients with a systemic disease. Transplant and rheumatoid arthritis were favorable at 33 month evolution. The immunosuppressive therapy required for the transplant helped the control of her articular disease.

We present a case of coronary artery fistula originating from the proximal left anterior descending coronary artery anterior to a critical atheromatous stenosis, draining into the main trunk of the pulmonary artery and with a third branch draining into the coronary vessel itself, distal to the lesion. The diagnosis was made when we were performing a diagnostic coronary arteriography on a patient with unstable angina. The possible association of the fistula and coronary atherosclerosis is discussed.

Permanent pacemaker implantation is required in a large number of transplantation patients principally because of sinus node dysfunction of the donor atrium. The most suitable mode of pacing in these cases is still subject to controversy. We describe one case of a single lead system of VDD stimulation and sensing of the recipient atrial signal in a 32-year-old patient with posttransplant symptomatic sinus node dysfunction. Physiological adaptation of rate was achieved with recovery of normal receptor sinus node function.

Arrhythmogenic right ventricular dysplasia is a rare disease that usually presents with ventricular arrhythmias and sometimes with heart failure. Rarely symptoms become severe and refractory to conventional therapy. We present the case of a 36-year-old man with this disease who had sustained ventricular arrhythmias and severe right heart failure. Because these symptoms were poorly controlled with medical therapy, cardiac transplantation was finally chosen as definitive treatment. The patient had a favorable course and now leads near-normal life.

We present the case of a young man who developed severe cardiomyopathy eight years after receiving high-dose doxorubicin therapy as treatment for diffuse lymphoblastic lymphoma. He underwent cardiac transplantation and eighteen months later the tumor has not recurred and the patient has no cardiac symptoms.
