ABSTRACT Background When it is not suitable to use the radial access in invasive coronary procedures, the ulnar technique is a feasible and safe alternative. The objective of the present study was to characterize the relevance of the ulnar technique in the daily practice of a center that adopts the radial strategy as the first option. Methods The sample was extracted from a single-center prospective registry, from May 2008 to October 2018, including all patients undergoing invasive coronary procedures in […]
ABSTRACT Background Race is a risk factor for coronary events that shows conflicting data and still has been scarcely studied in the Brazilian population. The present study aimed to assess the influence of race on the development of coronary artery disease, therapeutic outcomes, and major adverse events. Methods Data from the Central Nacional de Intervenções Cardiovasculares (CENIC) were retrospectively analyzed from June 2006 to March 2016, comparing profiles and results of interventions according to race. Results Mixed ethnic ancestry individuals […]
ABSTRACT The finding of ST segment elevation in the electrocardiogram identifies many patients with acute myocardial infarction, but presents low sensibility. Recently, some new electrocardiogram patterns have been described for the early identification of myocardial infarction. We report a case of a 53-year-old male patient who presented with an anterior myocardial infarction and an unusual electrocardiographic pattern. The electrocardiogram presented a slightly widened QRS complex, slow progression of the R wave in the anterior wall, and an ascending ST segment […]
ABSTRACT Background Chronic total occlusion is the subtype of lesions with the lowest procedural success rates, as well as the most common cause of incomplete revascularization and coronary artery bypass grafting. Their recanalization requires advanced techniques, dedicated materials, skilled operators and, usually, double arterial access, which makes the procedure more complex, increasing the chance of complications. Our goal is to characterize the most frequent complications in percutaneous treatment of chronic total occlusions in contemporary practice. Methods We searched the PubMed/MEDLINE […]
ABSTRACT Background Coronary chronic total occlusion is present in approximately one third of patients with coronary artery disease, and its management is challenging. Brazilian reports on percutaneous coronary intervention in this scenario are scarce. The objective of this study was to present contemporary data on percutaneous coronary intervention in chronic total occlusions. Methods We analyzed the clinical, angiographic and procedural characteristics of all coronary interventions in chronic total occlusions of the Central Nacional de Intervenções Cardio vasculares (CENIC) performed between […]
ABSTRACT Background Temporal trends in the female population submitted to percutaneous coronary intervention were evaluated as to clinical, angiographic and procedural aspects, based on analysis of 10-year results of a national registry. The objective of this study was to compare the in-hospital results and clinical outcomes by grouping the sample into three different time frames. Methods The database used was the Central Nacional de Intervenções Cardiovasculares (CENIC). A total of 59,931 women undergoing percutaneous coronary intervention between 2006 and 2016 […]
ABSTRACT Background Bifurcation lesions remain a challenge and little is known about the characteristics and outcomes of percutaneous coronary intervention over the last decade with the increasing use of drug-eluting stents. The objective of this study was to identify the patient profile and the in-hospital outcomes as well as the predictors of in-hospital death over time. Methods An observational, retrospective study that evaluated patients undergoing percutaneous coronary intervention for bifurcation lesions between 2006 and 2016. Patients were divided into three […]
Historically, chronic total occlusions (CTO) comprise the subgroup of the most difficult lesions to be treated by percutaneous techniques. CTO is one of the most important predictors of the need for coronary artery bypass grafting, of incomplete revascularization, and low success rates in attempts for percutaneous recanalization. In addition, CTO has been considered one of the factors associated with higher mortality rates in ST-segment or non-ST-segment elevation myocardial infarction patients. Many obstacles are faced when trying to perform target-vessel recanalization […]
ABSTRACT Coronary artery anomalies are congenital changes in their origin, course, and/or structure. Intercoronary communication is a very rare subset with uni- or bidirectional blood flow between two or more coronary arteries. We present the case of a 70-year-old male patient with acute coronary syndrome, and his coronary angiography incidentally showed a surprising and very rare communication between the left circumflex and right coronary arteries.
