ABSTRACT Background Same-day discharge for percutaneous coronary interventions is an attractive and safe strategy. Observational and randomized data show equivalent results as compared to overnight observation. In addition, it ensues great savings for the healthcare system. Nevertheless, in Brazil, this approach is underused. The objective of this study was to describe the characteristics and outcomes of patients undergoing percutaneous coronary intervention with same-day discharge. Methods A single-center study with patients who underwent selected procedures, uneventful, discharged on the same day. […]

ABSTRACT The volume of complex coronary interventions has grown in Brazil and worldwide. Since they are performed in patients at increasingly higher risks, new techniques have been developed when interventional cardiologists are faced with uncommon situations, such as no safe arterial access for the procedure. We report a case of a patient with severe peripheral artery disease and occluded right femoral artery, in whom a single access (left femoral artery) was used for positioning the Impella™ and the guidewire for […]

ABSTRACT Penetrating injuries to the heart are usually devastating and few patients survive the initial trauma. The most frequent penetrating injuries are caused by projectile injuries and less commonly by melee weapons. Most of these injuries involve chamber free walls and a small percentage can affect the interventricular septum. We report a case in which an emergency surgical procedure was successful in controlling cardiac tamponade, and repairing a right ventricular laceration caused by multiple stab wounds. Subsequently, a successful interventional […]

Abstract Aortic stenosis is the most prevalent valve disease in developed countries and has high morbidity and mortality after the onset of symptoms. The prevalence of severe aortic stenosis in elderly patients (>75 years) is approximately 3.4%. The transcatheter aortic valve replacement has been employed for approximately 20 years and had robust outcomes published. However, it is a challenging procedure when performed on a patient in cardiogenic shock, caused by severe deterioration of left ventricular function, a condition aggravated in […]

ABSTRACT Chronic total occlusion recanalization still represents the last frontier in percutaneous coronary intervention. Retrograde recanalization is one of the most significant amendments of the technique, and has recently become an essential complement to the classical antegrade approach. It has a high success rate with a low complication profile, despite frequent utilization in the most complex patients. Since its initial description, important iterations have occurred and made the technique safer, faster and more successful.

Abstract Left main coronary artery bifurcation represents one of the most challenging settings for the interventional cardiologists. The conventional stents are designed and shaped to restore tubular geometry, while the left main coronary artery bifurcation is far more complex with different diameters and non-tubular cross-sections. In relevant patients, two stent strategy is preferred over provisional T-stenting. The double-kissing crush has been the preferred double stent technique. We present a case in which the double-kissing approach was used in left main […]

Abstract 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 observational, retrospective study involving patients undergoing invasive diagnostic or therapeutic coronary procedures via distal radial access, with assessment of the radial artery patency by Doppler […]

Transradial access (TRA) offers important advantages over transfemoral approachs, including early patient ambulation, improved patient comfort, less vascular complications, lower health care costs, and reduced adverse cardiovascular events, including mortality. Nevertheless, complications of TRA still exist, and radial artery occlusion (RAO) occurred in up to 30% of cases, in a prospective vascular ultrasound study. Due to dual blood supply to the hand, RAO is usually asymptomatic and unnoticeable, although sometimes it may be associated with distal ischemia, paresthesia, pain at […]

ABSTRACT Prinzmetal angina is described as episodes of chest pain that occur at rest, associated with electrocardiographic changes in the ST-segment, which may or may not evolve to ischemia, and are not caused by coronary artery disease, having more recently been related to a coronary vasospasm. This diagnosis becomes especially challenging in patients who have already undergone previous percutaneous coronary procedures. We report a case of a patient diagnosed with Prinzmetal angina with a recent percutaneous coronary intervention due to […]

Abstract The prevalence of cerebrovascular complications after cardiac catheterization is low. These include stroke, transient ischemic attack, and amaurosis fugax. Cortical blindness is a rare, bilateral clinical condition of largely ischemic etiology, characterized by damage to the cerebral cortex, which manifests with acute reduction of visual acuity. Usually, neuro-ophthalmic complications of cardiac catheterization are correlated with embolic phenomena or migraine. We report a case of transient cortical blindness during coronary and aortocoronary bypass graft angiography.
