Background: The use of the distal radial access for invasive coronary procedures has been rapidly adopted by the medical community, but with no evaluation of efficacy and safety outcomes of this approach. The objective was to evaluate the rate of radial artery occlusion involved in this technique, using Doppler ultrasound. Methods: This was an obse...

Background: In high-expertise transradial (TR) centers, the radiation exposure to patients during coronary angiography (CAG) is equivalent to transfemoral use. However, there is no definitive information during TR-CAG regarding the use of a single, dedicated catheter to impart less radiation exposure to patients. Objective: We compare the radiat...

Importance It is unknown whether angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin II receptor blockers (ARBs) have a positive, neutral, or negative effect on clinical outcomes in patients with coronavirus disease 2019 (COVID-19). Objective To determine whether discontinuation compared with continuation of ACEIs or ARBs changed the n...

Objectives. To compare severe complications related to radial access and those related to femoral access using vascular closure devices for patients undergoing primary percutaneous coronary intervention (PCI). Background. Femoral artery access is still used for acute myocardial infarction management; studies comparing state-of-the-art radial and fe...

Background: Takotsubo syndrome (TTS) is an acquired form of cardiomyopathy. National Brazilian data on this condition are scarce. The Takotsubo Multicenter Registry (REMUTA) is the first to include multicenter data on this condition in Brazil. Objective: To describe the clinical characteristics, prognosis, in-hospital treatment, in-hospital mort...

Objectives: To report clinical, angiographic characteristics, outcomes, and predictors of unsuccessful procedures in patients who underwent chronic total occlusion (CTO) percutaneous coronary interventions (PCI) in Latin America. Background: CTO PCI has been increasingly performed worldwide, but there is a lack of information in this region. Me...

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 w...

A 69-year-old man underwent percutaneous coronary intervention of a left anterior descending coronary artery (LAD) diagonal bifurcation lesion with 2 platinum-chromium everolimus-eluting stents with the culotte technique in September 2014. Dual-antiplatelet therapy was maintained for 1 year. In March 2016 (18 months later), while only on aspirin, t...

Introduction: The recently described distal puncture of the left radial artery through the anatomical snuffbox (radial fossa) can be considered a refinement of the original technique. Its potential benefit is greater comfort to patients and operators, as well as maintenance of blood flow through the superficial palmar arch, in case of radial artery...

O implante percutâneo de bioprótese aórtica é a terapia estabelecida em pacientes com estenose aórtica grave. Houve um progressivo aperfeiçoamento na tecnologia dos dispositivos que, associada a maior experiência dos operadores, resultou em procedimentos mais seguros e com melhores resultados. O primeiro dispositivo de segunda geração aprovado no B...

Transcatheter aortic valve implantation is a well-established therapy in patients with severe aortic stenosis. There has been a progressive improvement in device technology associated with increased experience of the interventionists, resulting in safer procedures with better outcomes. The first second-generation device approved in Brazil, Lotus™ V...

Background: Studies demonstrate that radial artery access reduces the risk of vascular and bleeding complications associated to percutaneous coronary intervention. Our objective was to evaluate in-hospital results of the transradial approach in elderly patients undergoing percutaneous coronary intervention. Methods: Prospective registry including...

Thirty-seven-year-old female, previously diagnosed with mitral valve stenosis due to rheumatic fever, who had successfully undergone percutaneous mitral valvotomy in 1996, 2000 and 2005. Forty-one months after the third procedure, in addition to episodes of paroxystic atrial fibrillation, the patient had dyspnea after ordinary exertion. Echocardiog...

BACKGROUND: Percutaneous coronary intervention in saphenous vein grafts remain a major challenge due to the high complication rates associated to the procedure. The new balloon-expandable MGuardTM stent was developed with an ultra-thin mesh sleeve attached to its outer surface, designed to reduce distal embolization during the procedure. Our object...

BACKGROUND: Percutaneous coronary intervention (PCI)related bleeding is a frequent complication whose prognosis is often neglected. Several studies have shown the adverse clinical impact of bleeding, especially increased short and long-term mortality rates. The purpose of this study was to evaluate predictors and clinical impact of this complicatio...
