[4 proposals for ventricular remodelling in the surgical treatment of dilated myocardiopathy].

Four surgical procedures are proposed to achieve an efficient remodelling of the ventricles with a low injury to heart muscle, for the treatment of the dilated cardiomyopathy. Those procedures are based the partial ventriculectomy technique of Batista an on the new conception of the macroscopical myocardium structure of the ventricles evidenced in the second half of the present century.

Epidemiologic evidence of transmission of donor-related bacterial infection through a transplanted heart.

This study describes a patient who had fulminant infectious myocarditis as a result of methicillin-resistant Staphylococcus aureus after receiving a heart transplant from an infected donor. There was complete concordance of typing results between donor and recipient strains that were different from the 20 isolates with which they were compared. Molecular epidemiologic study provided compelling evidence that a transplanted organ can transmit a bacterial infection from the donor to the recipient.

Spectrum of alcohol-induced myocardial damage detected by indium-111-labeled monoclonal antimyosin antibodies.

Objectives: We sought to determine the prevalence, intensity and evolving changes of myocardial damage detected by myocardial uptake of antimyosin antibodies in patients with alcohol-induced dilated cardiomyopathy, alcohol addicts attending a detoxification unit and healthy subjects with short-term alcohol consumption.

Background: Evidence of alcohol-induced myocardial damage may be provided by myocardial uptake of indium-111-labeled monoclonal antimyosin antibodies. The spectrum of such damage in patients who are heavy drinkers (> 100 g for > 10 years), with or without cardiomyopathy, and the impact of short-term alcohol ingestion on antimyosin antibody uptake have not been adequately explored.

[Atypical coarctation. Repair with Dacron graft and aortic sarcoma].

A patient with a localized severe stenosis of his lower thoracic aorta is described. He presented a coarctation like syndrome with hypertension, pulseless legs and left ventricular failure. At surgery a biopsy of the lesion and bypass graft were performed.

[Bilateral pulmonary thromboendarterectomy in chronic pulmonary thromboembolism. A case report and review of the literature].

A 39-years-old male patient with chronic venous insufficiency, deep venous thrombosis and recurrent pulmonary embolism in the past medical history. After syncopal event was diagnosed of bilateral chronic pulmonary embolism, pulmonary hypertension and right ventricular failure. Fibrinolytic treatment was no effective therapeutic modality.

Indium-111-monoclonal antimyosin antibody studies after the first year of heart transplantation. Identification of risk groups for developing rejection during long-term follow-up and clinical implications.

The long-term clinical course and results of biopsies in 21 patients studied with monoclonal antimyosin antibodies more than 12 months after heart transplantation according to the presence and degree of antimyosin-antibody uptake is described. Eighteen men and three women aged 20-52 years (39 +/- 9 years) were studied with antimyosin antibodies 12-40 months (mean, 22 +/- 9 months) after heart transplantation, and followed for a mean of 18 months (10-28 months). The number of biopsies performed during follow-up was 102.

Dopamine treatment of locally procured donor hearts: relevance on postoperative cardiac histology and function.

Unlabelled: Administration of catecholamines can lead to myocyte damage. Dopamine treatment is often used in potential cardiac donors to attain hemodynamic stability. Donor hearts exposed to dopamine are rejected or selected for transplantation without clearly defined criteria.

Patterns of evolution of myocyte damage after human heart transplantation detected by indium-111 monoclonal antimyosin.

The indium-111 labeled Fab fragment of antimyosin monoclonal antibody was used to study cardiac rejection and the time course of myocyte damage after transplantation. Fifty-three studies were performed in 21 patients, 17 men and 4 women, aged 19 to 54 years (mean 37 +/- 8), from 7 to 40 months after transplantation. Repeat studies were available in 8, and 10 were studied after the first year of transplantation.
