ABSTRACT Valve-in-valve procedures are likely to become increasingly frequent with the aging of the population and the increasing number of surgical bioprostheses implanted. More than 50% of these implanted valves have small diameters, which hinders the good expansion of transcatheter devices, leading to higher final gradients. Therefore, post-dilation is required to optimize implantation of the new device. Compliant balloons have limitations and a higher potential to rupture when used for this purpose. We describe a case of a valve-in-valve procedure […]

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 […]

The attempt to identify patients who are more likely to present events, whether or not related to interventions, is a long search preceding the era of catheters.1.2 In 1977, for example, some of the most important predictors of adverse events related to coronary artery disease (CAD) were defined, such as the number of coronary vessels or territories involved, and the extent of myocardium at risk. The prognostic capacity of these variables was demonstrated to increase with the incorporation of other […]

ABSTRACT Percutaneous left atrial appendage closure is an invasive option for cardioembolic event prevention and it is indicated for patients presenting non-valvular atrial fibrillation and oral anticoagulation therapy failure or contraindication. There is limited data addressing the technical success of percutaneous left atrial appendage closure in patients with complex anatomy and history of previous atrial septal defect repair surgery. We report a case of left atrial appendage closure performed with the LAmbre™ device (LifeTech Scientific, Shenzhen, China) in a patient […]

Description of rare diseases, special patients or situations, and innovative diagnostic or therapeutic approaches comprise the objectives of the Case Reports published in the Journal of Transcatheter Interventions (JOTCI). Considering the manuscripts submitted after the reformulation of the journal, this type of article accounts for approximately 40% of materials received by the editorial production. However, how can we confront the traditional literature with the reality and current speed of some social media, such as Twitter, which enable immediate and unrestricted […]

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.

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 […]
