OBJECTIVE The results obtained in 43 patients using direct intraoperative radiofrequency catheter ablation, as an alternative to surgical incisions, to perform atrial fibrillation surgery, are presented. METHODS Forty-three patients with ages ranging from 43 to 74 years (x = 59), with chronic atrial fibrillation with an average duration 6+/-5 years were(More)
OBJECTIVES Because the autonomic nervous system is an important determinant in the appearance of atrial fibrillation, we have assessed the role of ventral cardiac denervation for its prevention. METHODS Patients undergoing low-risk coronary artery surgery were enrolled. No routine antiarrhythmic drugs were administered before or after the operation.(More)
BACKGROUND To assess the efficacy of a new catheter for intraoperative radiofrequency ablation. METHODS We operated 35 mitral patients with atrial fibrillation of which 27 had chronic atrial fibrillation with a mean duration of 8 +/- 6 years. Most patients were in functional class III or IV. All patients were operated under cardiopulmonary bypass using(More)
In a series of 41 patients of ASD (ostium secundum type) corrected by surgery, a clinical, radiological, electrocardiographic and echocardiographic follow-up study was performed. Good clinical results were obtained but some abnormalities can persist postoperatively: RV enlargement, dysrhythmias and mitral valve dysfunction.
UNLABELLED Cardiac allograft vasculopathy is the main cause of morbidity and mortality after cardiac transplantation. Intravascular ultrasound (IVUS) is a sensitive imaging technique that provides detailed quantification of coronary atherosclerosis burden and could be a complement to routine angiography. AIM To determine the value of IVUS for detecting(More)
Endomyocardial biopsy is still the principal method for diagnosing cardiac allograft rejection. However, this procedure can be associated, albeit rarely, with potentially serious complications. We describe the case of a patient with extensive anterior myocardial infarction without revascularization, who developed cardiogenic shock and required heart(More)
Radiofrequency ablation is successful in most supraventricular tachyarrhythmias and the first results in percutaneous applications in atrial fibrillation have been published. At present, all the surgical techniques for the treatment of atrial fibrillation use extensive atrial incisions. A case report is presented of a 67 year old woman with chronic atrial(More)
The Ross operation is physiologically the best approach for aortic valve replacement. At the Hospital de Santa Cruz 22 consecutive pulmonary autograft operations have been performed in patients with a mean age of 49 (range 17-65) years. Six patients had mitral valve disease, two had aortic aneurysms and one had a ventricular septal defect. Subcoronary(More)
A low-cost modular compact personal computer-based system for surface precordial mapping (SPM) developed by the authors was used to detect rejection periods, documented by endomyocardial biopsy (EB), in heart transplant patients on cyclosporine A therapy. Data were collected with a matrix of 35 Ag-AgCl electrodes positioned over the precordio with(More)
INTRODUCTION The prognostic value of peak oxygen uptake (peak VO2) in patients with left ventricular systolic dysfunction is currently recognized and accepted. Some studies have shown that other cardiopulmonary exercise test (CPET) parameters have additional value. OBJECTIVES To evaluate whether our population of patients with left ventricular dysfunction(More)
