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)
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)
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.
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)
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)
Dilated cardiomyopathy (DCM) is a myocardial disease, characterized by ventricular dilatation and impaired systolic function, that in more than 30% of cases has a familial or genetic origin. Given its age-dependent penetrance, DCM frequently manifests in adults by signs or symptoms of heart failure, arrhythmias or sudden death. The predominant mode of(More)
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)
The initial experience with percutaneous transluminal coronary angioplasty (PTCA) at Santa Cruz Hospital is presented. Between May and November 1984, ten patients with single significant (> 75%) coronary artery obstructions, 8 of the left anterior descending (LAD), 1 of the circumflex (Cx) and one of the right coronary artery (RCA), underwent coronary(More)
AIM To evaluate the morbidity and mortality after heart transplantation in the patients treated at Santa Cruz Hospital. METHODS Between February 1986 and December 2000, 113 patients underwent orthotopic heart transplantation at Santa Cruz Hospital. Actuarial survival rates at 12 months, 5 and 10 years after surgery were calculated (Kaplan-Meier analysis).(More)
