OBJECTIVES: Ebstein anomaly is a congenital defect characterized by a lack of delamination and apical displacement of the tricuspid valve, tricuspid insufficiency, right atrial enlargement, and ventricular dysfunction. To analyze the results and evolution of the different surgical strategies, data were collected from 45 patients operated on during 1990-2018. Twenty-six patients were included with a median age at initial surgery of 11.3 years (range: 13 days-18.6 years). METHOD: Procedures were plastic 10 patients (38%), cone technique reconstruction 11 (42%), and replacement 5 (19%)...

OBJECTIVE: Clinical practice guidelines suggest performing an electrocardiogram (EKG) in patients with chest pain within the first 10 minutes in the emergency department, warning about subdiagnosis in women. Possible differences based on sex were analyzed. METHOD: An observational and retrospective study in an Emergency Department, with adult patients admitted to the Chest Pain Unit in 2021. RESULTS: There were 1,469 patients, of whom 774 were men (52...

OBJECTIVE: To describe the initial experience of cardiac contractility modulation (CCM) implantation in Latin America. METHOD: We present the first two cases in Latin America of patients with heart failure with reduced left ventricular ejection fraction (LVEF) not candidates for cardiac resynchronization therapy in whom a CCM device was implanted. Results. RESULTS: In both patients we described improvement of the 6-minute walk test, functional class according to the NYHA and LVEF...

OBJECTIVE: To evaluate the efficacy of a cardiac rehabilitation program (CRP) in improving adherence to non-pharmacological secondary prevention in patients with acute coronary syndrome (ACS). METHOD: Retrospective study of patients with ACS referred to CRP in a tertiary hospital from 2018 to 2021. Pre-post differences in adherence to physical activity, Mediterranean diet, smoking, and motivation to change were analyzed. Age, sex, and baseline motivation were analyzed in predicting change in adherence...

Aneurysms are clinical entities that can develop and affect human aorta; and although in most cases they have an asymptomatic course, these pathological dilatations can lead to a lethal outcome when rupture occurs, thus the establishment of predictors is crucial for death prevention. Essential events that take place in the vessel wall have been identified and described, such as inflammation, proteolysis, smooth muscle cell apoptosis, angiogenesis, and vascular remodeling. Porcine and ovine models have been useful for the development and evaluation of endovascular devices of the aorta...

BACKGROUND: The decision to close patent ductus arteriosus should always be individualized and taken together with the child's family once the risks and benefits of both choices have been exposed. OBJECTIVE: This study aims to report the experience and outcomes in patients undergoing endovascular closure of small to medium-size PDA with a Nit-Occlud® device in a tertiary referral hospital in Colombia. METHODS: Longitudinal descriptive study, which included all patients under 18 years of age who underwent percutaneous ductal closure with Nit-Occlud® device between January 1, 2011, and February 1, 2023...

BACKGROUND: Different pathogens can cause dilated cardiomyopathy, one of them is Trypanosoma cruzi protozoan. T.cruzi-chronic infection causes chronic Chagasic cardiomyopathy and affects the sinus node and the conduction systembelow the bundle of His; besides, it shows excellent arrhythmogenic potential because of ventricular arrhythmias. Knowingthe clinical characteristics and performing serological tests to diagnose chronic Chagasic cardiomyopathy is essential. The serological diagnosis for searching the antibodies is based on the phase, which can be a predictor for the development of dilated cardiomyopathy...

Atrial fibrillation (AF) is the most prevalent arrhythmia and is related with significant morbidity, mortality and costs. In spite of relevant advances in the prevention of embolic events and rhythm control, little has been done to reduce its prevalence, progression and impact, since it increases with ageing as well as with common risk factors such as alcohol intake, tobacco use and stress as well as with arterial hypertension, diabetes mellitus, heart failure, sleep apnea, kidney failure, chronic pulmonary obstructive disease, ischemic heart disease and stroke, among other important comorbidities...

BACKGROUND: Aneurysms and diverticula of the left ventricle are rare entities in childhood, with a prevalence of less than 0.1%. Described since 1886, as a severe and potentially fatal disease if not corrected, mainly due to the presence of associated anomalies and the risk of rupture. OBJETIVE: Present other management options for ventricular diverticula, different from surgical options, using alternative materials that are not used very often in daily practice...

OBJECTIVE: Analyze sex hormone's influence during Chagas´ Disease. METHODS: Male and female BALB/c mice were divided into six groups, four experimental (sham, orchiectomized, orchiectomized and supplemented with estradiol, orchiectomized supplemented with testosterone, oophorectomized, oophorectomized and supplemented with estradiol, and oophorectomized and supplemented with testosterone), and two control (healthy and intraperitoneally with T. cruzi strain NINOA infected)...

This review provides an overview of the efficacy and safety of renal sympathetic denervation as a therapeutic approach for resistant hypertension. While the initial enthusiasm was sparked by the results of early clinical trials, it was dampened by the findings of the Symplicity HTN-3 study. However, recent advances in catheter technology and more refined patient selection criteria have yielded more promising results. Subsequent studies, such as SPYRAL HTN-OFF MED and RADIANCE II, demonstrated significant reductions in blood pressure, even in patients with mild to moderate hypertension...

Chronic thromboembolic pulmonary hypertension (CTEPH) is a subtype of pulmonary hypertension characterized by the obstruction of pulmonary arteries secondary to chronic thromboembolism. Pulmonary thromboendarterectomy surgery (PTE) is the main treatment for patients with CTEPH, as it removes the chronic thrombi from the pulmonary arteries. Pulmonary reperfusion syndrome is a common complication of the surgery, which involves the development of pulmonary edema in the area where blood perfusion improves after the surgery...
