ABSTRACT The disease caused by COVID-2019 has caused an impact on worldwide realities, including care of patients at clinics and hospitals. The medical societies have recommended patients in stable clinical conditions to stay at home, in order to reduce exposure of healthcare teams and patients. Elective cardiac catheterization procedures should be postponed; however, if performed, some measures must be taken, such as minimizing the number of staff in the room, testing patients for COVID-19 and using appropriate personal protection equipment.

ABSTRACT Transcatheter aortic valve replacement is indicated as an alternative to conventional surgical treatment for elderly patients with low, moderate, and high surgical risk, or as the best therapeutic strategy for patients considered inoperable. The transfemoral vascular access is the preferred route for replacement. However, in a small portion of the population, this access is not possible for anatomical reasons. Access through the brachiocephalic trunk may be an option in specific cases. Nevertheless, data on feasibility and safety of this […]

ABSTRACT Background The outbreak of coronavirus disease 2019 (COVID-19), a disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was characterized as a pandemic by the World Health Organization, with high fatality rate. The number of registered cases has skyrocketed, as well as the number of deaths. Half of the patients with COVID-19 have chronic conditions, especially cardiovascular and cerebrovascular diseases, followed by diabetes mellitus, increasing their morbidity and mortality. Several studies have demonstrated this correlation, however a […]

ABSTRACT An octogenarian female patient, admitted for heart failure secondary to severe aortic stenosis decompensated by atrial fibrillation, with a high ventricular response. When clinically compensated, she was discharged on oral anticoagulation with a direct-acting anticoagulant, for outpatient scheduling of a transcatheter implantation of aortic valve bioprosthesis. She was readmitted early due to low digestive bleeding secondary to locally advanced stenosing colon cancer. After discussion with the Heart Team and the oncology team, a transcatheter implantation of aortic valve bioprosthesis […]

The severe acute respiratory syndrome coronavirus (SARS-CoV-2), identified in December 2019, in Wuhan, China, is an enveloped, single-stranded RNA genome betacoronavirus that causes pneumonia and severe respiratory failure, which characterize the coronavirus disease 2019 (COVID-19). – This disease was considered a pandemic by the World Health Organization (WHO) and, currently, more than 7.5 million people in the world have already been affected. Due to the high transmission rate of the disease, which requires healthcare assistance and hospitalization, with the possibility […]

ABSTRACT Patent foramen ovale is associated with the occurrence of cryptogenic ischemic stroke, and its occlusion decreases the recurrence rate. Percutaneous occlusion is safe and effective, and can be performed by different types of occluders. The choice of the device must consider the anatomy of the interatrial septum and the foramen ovale, the availability of the device and the team’s experience. Usually, dedicated devices are preferred. However, in the presence of a lipomatous hypertrophy of the septum, due to its […]

ABSTRACT Since the advent of balloon angioplasty in 1977, countless tools and techniques have been introduced and broadened the application of percutaneous coronary intervention in unprecedented anatomic settings. Heavily calcified coronary lesions traditionally continue to pose a challenge for percutaneous coronary intervention, since they are difficult to dilate adequately and/or there is inability to deliver and deploy drug eluting stents appropriately. Poor stent deployment is associated with increased procedural complications and suboptimal long-term outcomes. Thanks to the introduction of dedicated […]

ABSTRACT Background Percutaneous treatment for atrial septal defects is utilized worldwide as first-line therapy. Its use is restricted to atrial septal defects localized within the confines of the oval fossa. All other atrial septal communications are, traditionally, submitted to surgery. Sinus venosus atrial septal defect is the second most frequent type of atrial septal defects. The diameters are usually large and thus prone to right heart overload. Besides that, it is difficult to be diagnosed by transthoracic echocardiography, and often […]

ABSTRACT Transcatheter aortic valve implantation is one of the main treatment strategies for severe symptomatic aortic valve stenosis. The expansion of indications for low surgical risk patients has been based on recent studies. In this scenario, a younger population with bicuspid aortic valves is expected to be more frequently submitted to transcatheter valve replacement, given this anatomic profile is generally associated with larger aortic rings. There is no consensus on the best technique to use on these cases. We describe […]

ABSTRACT Despite the well-known benefits of transradial access, critically-ill patients presenting with cardiogenic shock are usually submitted to coronary angiography and percutaneous coronary intervention via classic transfemoral access, mainly due to difficult puncture of radial artery in the setting of hemodynamic instability. We report a challenging case of anterior ST-segment elevation myocardial infarction, complicated by cardiogenic shock, requiring primary percutaneous coronary intervention of ostial left anterior descending artery with two-stents technique, safely and successfully performed via right distal transradial access.
