ABSTRACT 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 occlusion. Our goal was to evaluate the safety and feasibility of this new approach. Methods A prospective registry of patients who underwent invasive diagnostic or therapeutic […]

ABSTRACT Background Radial access has been widely used in percutaneous coronary procedures. Occlusion of the radial artery is the most important vascular complication related to the duration of compression time after radial access for cardiac catheterization. The objective of this study was to compare the efficacy and safety of hemostasis for 2 or 3 hours after diagnostic cardiac catheterization via radial approach. Methods A prospective, randomized study with 206 patients recruited after cardiac catheterization using radial access, between November 2014 […]

ABSTRACT The use of iodinated contrast media in coronary procedures may lead to contrast-induced nephropathy – particularly in older adults, diabetic individuals and patients with previous renal disease – and increase morbidity and mortality. There is no specific treatment for this condition; therefore, use of low contrast volumes and previous hydration remain the best prevention strategies. A case of percutaneous coronary intervention without contrast agent administration, involving an elderly female patient with chronic renal insufficiency and stable angina, is described. […]

ABSTRACT Entrapment and breakage of devices used in coronary interventions are rare complications, but have occurred with increasing frequency. Knowledge and mastery of techniques to rescue these materials are of paramount importance to solve these incidents. We report a successful withdrawal of a 0.014” retained guidewire in the coronary artery, by the so-called twin guidewire technique.

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 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 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 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 […]
