Abstract Background Alcohol septal ablation (ASA) is an alternative to surgical myectomy for patients with symptomatic hypertrophic obstructive cardiomyopathy (HOCM) and significant left ventricular (LV) outflow tract (LVOT) obstruction. Although widely studied worldwide, data on ASA outcomes in Brazil are still limited. Objective To assess the safety and effectiveness of ASA in symptomatic HOCM patients receiving optimal medical therapy using current techniques across multiple centers in Brazil. Methods Patients with HOCM and angina (classified by the Canadian Cardiovascular Society [CCS]) […]

Abstract Background Previous studies have shown that women with coronary artery disease (CAD) are less likely to undergo angiography and have less favorable outcomes after percutaneous coronary intervention (PCI). Objectives Assess the outcomes of women with acute coronary syndrome (ACS) and stable CAD (lesion>50%) treated with contemporary PCI using DES. Methods Observational, longitudinal cohort study with prospective follow-up included all female patients ≥ 18 years admitted at a tertiary public cardiovascular center in Brazil from January 2019 to December 2020. […]

Abstract Infective endocarditis in the pediatric population is a rare condition that may or may not be associated with a congenital heart disease. Current treatment modalities are based on long-term antibiotic therapy and surgical resection as the first option for cases of persistent vegetation. We present a case of successful percutaneous retrieval of a vegetation in a patent ductus arteriosus, that extended to the pulmonary artery trunk in a pediatric patient. This is the first report in the literature on […]

Dear Editor, I have read with interest the study titled “The Predictive Value of the Inflammatory Prognostic Index for Detecting No-Reflow in ST-Elevation Myocardial Infarction Patients”, published in your journal. I would like to contribute to the study by providing some insights. […]

Abstract Background: Early reperfusion therapy is acknowledged as the most effective approach for reducing case fatality rates in patients with ST-segment elevation myocardial infarction (STEMI). Objective: Estimate the clinical and economic consequences of delaying reperfusion in patients with STEMI. Methods: This retrospective cohort study evaluated mortality rates and the total expenses incurred by delaying reperfusion therapy among 2622 individuals with STEMI. Costs of in-hospital care and lost productivity due to death or disability were estimated from the perspective of the […]

Abstract Background Women, in comparison to men, experience worse outcomes after acute coronary syndrome (ACS). However, whether the female sex per se is an independent predictor of such adverse events remains unclear. Objective This study aims to assess the association between the female sex and in-hospital mortality after ST-elevation myocardial infarction (STEMI). Methods We conducted a retrospective cohort study by enrolling consecutive STEMI patients admitted to a tertiary hospital from January 2018 to February 2019. All patients were treated per […]
