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 Penetrating aortic ulcer is a rare entity with a poor prognosis within the spectrum of acute aortic syndrome. Even rarer are the cases located in the ascending aorta. This case demonstrates the importance of ancillary imaging methods for correct diagnosis and choice of the most appropriate management of this atypical presentation of the disease.
ABSTRACT Background The radial approach for cardiac catheterization and coronary angioplasty is well established. The prevalence of radial artery occlusion and its determining factors still raises debate. The objective of this study was to analyze the incidence of radial artery occlusion after cardiac procedures using the radial approach, comparing hemostasis done by elastic compression dressing or hemostatic wristband. Methods A randomized clinical trial comparing the incidence of radial artery occlusion as established by palpation and vascular Doppler, upon discharge and […]
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 Background The anomalous origin of coronary arteries is uncommon in patients undergoing coronary angiography. In some cases, in their course, they may be subjected to extrinsic compression, which results in myocardial ischemia. The present study aimed to report the prevalence, clinical features and prognostic impact of the anomalous origin of the right coronary artery from the left sinus of Valsalva. Methods We tracked down the medical records of the procedures performed in an interventional cardiology service, between 1999 and […]
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 The anomalous origin of the left coronary artery from the pulmonary artery, or Bland-White-Garland syndrome, is a rare congenital coronary anomaly that results in altered myocardial perfusion and left-right shunt. Ninety percent of patients with this syndrome die within the first year of life if the condition is left untreated. Diagnosis of this abnormality in adulthood is even rarer. We describe the cardiac catheterization and coronary computed tomography angiography findings of a recently diagnosed 27-year-old patient who underwent surgical […]
