Journal of Transcatheter Interventions

The Revista Brasileira de Cardiologia Invasiva(RBCI) celebrates 26 years in 2018, and will go through a reformulation, changing its title to Journal of Transcatheter Interventions (JOTCI), according to the decision to internationalize it, taken in meetings with the members of the Editorial Board of RBCI and the board of the Sociedade Brasileira de Hemodinâmica e Cardiologia Intervencionista(SBHCI). This reformulation will not be restricted merely to the title, but will include an exclusively electronic presentation and a new website with a […]

ABSTRACT Background: This study aimed to determine the correspondence between the anterior dot sign at the angiography and the malignant interarterial course, defined by the gold standard coronary angiography (angio-CT), in individuals with right coronary artery originating in the contralateral sinus of Valsalva. Methods: This was an observational, retrospective, and single-center study. All individuals who had both coronary angio-CT and invasive coronary angiography (ICA), and a diagnosis of right coronary artery anomaly originating in the contralateral sinus of Valsalva were […]

ABSTRACT Background: Catheter-based radiofrequency renal denervation has emerged as a promising tool for blood pressure control in patients with resistant hypertension. The aim of the present study was to evaluate the feasibility and safety of percutaneous renal sympathetic denervation by radiofrequency ablation using an irrigated-tip catheter in patients with true resistant hypertension. Methods: A saline-irrigated catheter was used for renal sympathetic denervation. The sample consisted of a consecutive series of 11 patients with resistant hypertension based on office blood pressure […]

ABSTRACT Background: The diagnosis of coronary artery disease is challenging because of the considerable variability in its clinical presentation. It also requires a cautious decision between invasive or conservative stratification. We aimed to evaluate the adequacy of coronary angiography indication in patients from the Unified Health System (SUS, in the Portuguese acronym) based on the guidelines for stable coronary disease. Methods: Consecutive patients who underwent coronary angiography between March 2014 and November 2015 were evaluated. Clinical presentation and functional tests […]

ABSTRACT Background: Percutaneous coronary intervention (PCI) in small-caliber arteries corresponds to 30 to 40% of invasive therapeutic procedures and shows high and persistent rates of restenosis, despite the evolution of the devices used. The objective of this study was to evaluate changes in patient outcomes associated with the evolution of this therapeutic modality in Brazil during the last 10 years. Methods: A total of 24,895 patients from the National Center for Cardiovascular Interventions (CENIC) registry were included. These patients were […]

ABSTRACT Background: Percutaneous coronary intervention (PCI) in large vessels has peculiarities that have been little explored in studies. Our objective was to evaluate temporal trends over the last 10 years and in-hospital outcomes for this population. Methods: Using data from the National Center for Cardiovascular Interventions (CENIC), procedures performed between June 2006 and March 2016 were analyzed. The data were divided into three periods (2006-2008, 2009-2011 and 2012-2016). Clinical, angiographic, therapeutic and in-hospital outcome data were considered. Results: The sample […]

ABSTRACT Background: Coronary chronic total occlusion (CTO) is present in approximately 15% of coronary angiographies, and the success rates of percutaneous coronary interventions (PCI) range from 55 to 80%. The radial access has been increasingly used, even in more complex scenarios, such as CTO. The objective was to compare the profile and results of CTO patients undergoing PCI by radial or femoral access, and evaluate the independent predictors of in-hospital mortality. Methods: Data from the CENIC registry on patients submitted […]

ABSTRACT Introduction: Percutaneous coronary intervention (PCI) in patients with multivessel disease is associated with a lower success rate and a higher incidence of complications. The results of this treatment in Brazil are poorly studied. The objective of this study was to analyze the results of PCI performed in patients with multivessel disease, which were registered in the National Center for Cardiovascular Interventions (CENIC) registry. Methods: Complete electronic records of procedures performed in patients with multivessel disease from 2006 to 2016 […]

ABSTRACT Spontaneous coronary dissection is an uncommon cause of acute coronary syndrome that may manifest as unstable angina, acute myocardial infarction, or sudden death. The condition occurs predominantly in women, with approximately one-third of cases reported during or after pregnancy. The etiology is unknown; however, associations with fibromuscular dysplasia and connective tissue diseases have been reported. Here, we describe a case of ST-segment elevation acute myocardial infarction in a puerperal woman due to spontaneous dissection of the left main coronary […]

ABSTRACT The anomalous origin of the left coronary artery from the pulmonary artery, or Bland-White-Garland syndrome, is a rare congenital coronary anomaly that results in altered myocardial perfusion and left-right shunt. Ninety percent of patients with this syndrome die within the first year of life if the condition is left untreated. Diagnosis of this abnormality in adulthood is even rarer. We describe the cardiac catheterization and coronary computed tomography angiography findings of a recently diagnosed 27-year-old patient who underwent surgical […]
