ABSTRACT Background The angiographic characteristics associated with saphenous vein graft degeneration and the high-risk profile of these patients increase the probability of adverse outcomes during and after percutaneous coronary intervention. This study set out to analyze the clinical and angiographic profile of patients, procedural characteristics, and hospital outcomes of percutaneous coronary intervention performed in saphenous vein grafts, and to investigate predictors of in-hospital mortality in this group. Methods A retrospective, observational study based on records kept by Central Nacional de […]

The Journal of Transcatheter Interventions (JOTCI), a continuation of the Revista Brasileira de Cardiologia Invasiva, has gone through several changes this year, and we hope they will please readers and authors. These modifications demanded time and untiring endeavor of a group of dedicated professionals, including our Managing Editor and expert Edna Rother; our Editorial Secretary, Viviane Zeppelini; the digital design company Cabo Verde; and the diagramming company Rudolf Serviços Gráficos, aiming to adjust our publication to the most current trends […]

ABSTRACT Contrast-induced acute kidney injury is not a rare event after exposure to contrast media, and affects approximately 1 to 2% of patients in general radiological imaging procedures. The incidence of contrast-induced acute kidney injury is even higher among patients undergoing percutaneous coronary intervention, and ranges from 3 to 19% according to the patient’s risk profile. It is associated with increased morbidity, mortality, hospital length-of-stay and healthcare costs. Hence, since there is no targeted treatment after its onset, identifying high […]

ABSTRACT Background The choice of the radial access for performing percutaneous coronary interventions has grown due to evidence of the greater benefits of the technique, such as reduced vascular complications, lower bleeding rates, early ambulation, shorter hospital stay and lower costs. The present study aimed to analyze patients submitted to percutaneous coronary intervention using the radial access in comparison to the femoral artery access in elective cases or in acute coronary syndromes. Methods An observational, single center study based on […]

ABSTRACT Background Individualized use of glycoprotein IIb/IIIa inhibitors during primary percutaneous coronary intervention in scenarios with high thrombotic load or occurrence of coronary flow abnormalities may be considered, despite scarce scientific evidence. Our objective was to compare patients undergoing primary percutaneous coronary intervention treated or not with glycoprotein IIb/IIIa inhibitors during the procedure. Methods A national, multicenter, retrospective study that included consecutive patients undergoing primary percutaneous coronary intervention, treated or not with glycoprotein IIb/IIIa inhibitors, between June 2006 and March […]

ABSTRACT Optical coherence tomography is an intravascular imaging tool that has been increasingly used in the cardiac catheterization laboratory. Since its spatial resolution is approximately ten-fold greater than intracoronary ultrasound, optical coherence tomography assists in the anatomical differential diagnosis of coronary lesions with atypical presentation. In this report, we present a case of a female patient with a history of acute coronary syndrome and, currently, with a complex angiographic lesion, with the aspect of a chronic dissection in the anterior […]

ABSTRACT Background Percutaneous intervention for obstructive lesions of the unprotected left main coronary artery is complex. Choosing the vascular access can be decisive to a successful procedure. The objective of the present study was to describe the characteristics and hospital outcomes of patients with unprotected left main coronary artery disease and compare the radial and femoral access approaches. Methods Clinical and angiographic data, access routes and hospital outcomes of patients that have undergone percutaneous coronary intervention of the unprotected left […]

ABSTRACT Background Manual thromboaspiration during primary percutaneous coronary intervention was very often used in the end of the last decade; however, there was a drop in its recommendation class due to results of recent publications. The objective of this work was to evaluate the use of this technique in Brazil. Methods Based on data from the Central Nacional de Intervenções Cardiovasculares (CENIC) in the period 2008 to 2016, we assessed patients submitted to primary percutaneous coronary intervention and manual thromboaspiration. […]

ABSTRACT Background In ST-segment elevation myocardial infarction, the need for early recanalization of the culprit artery, associated to the difficult access of the general population to medical services that provide such treatment, contribute to increased mortality in such patients. This is the rationale for implementing the LATIN project, acronym for Latin America Telemedicine Infarct Network, in areas characterized by high demographic density and difficult access to healthcare services. The objective of the present study was to analyze the first year […]

ABSTRACT Background As the population ages, the prevalence of diseases has increased, particularly that of coronary artery disease requiring treatment. The objective of this study was to assess the temporal evolution of percutaneous coronary intervention in octogenarians in Brazil. Methods Based on data from the Central Nacional de Intervenções Cardiovasculares (CENIC), we analyzed procedures carried out in patients aged 80 years and over, from June 2006 to March 2016, classified into three time ranges: 2006-2008, 2009-2011 and 2012-2016. We assessed […]
