ABSTRACT We present a case report in which a conventional intervention for the correction of atrial septal defect resulted in an exploratory videolaparoscopy and exeresis of an ovarian cyst. Atrial septal defect is one of the primary congenital cardiopathies diagnosed in adults; ovarian cysts present a high prevalence and are frequently asymptomatic. The possible relation between atrial septal defect and ovarian cyst is debated. The femoral venous puncture techniques, guided by anatomic landmarks and by ultrasonography, are analyzed from the […]

ABSTRACT Right coronary artery aneurysms are rare and may result from severe coronary disease, with few cases described in the literature. Mortality is high, and therapy is still controversial. We report the case of a 72-year-old woman with arterial hypertension, and a family history of coronary artery disease, who evolved for 2 months with episodes of palpitations and dyspnea on moderate exertion. During the evaluation, a giant aneurysm was found in the proximal third of the right coronary artery. The […]

ABSTRACT Coronary artery perforation is a rare but potentially lethal complication of percutaneous coronary intervention, mainly due to hemodynamic compromise secondary to cardiac tamponade development. All interventional cardiologists must thus be able to promptly recognize and solve coronary artery perforation. We describe a successfully and conservatively managed type III coronary artery perforation with prolonged balloon inflations, in the absence of covered stents and without compromising the percutaneous coronary intervention result by anticoagulation reversal.

ABSTRACT Coronary arteriovenous fistulas are rare anomalies that connect one or more coronary arteries to a cardiac chamber or other vascular structure. These communications can be occluded using percutaneous treatment, and there are currently several approaches and techniques. We report the case of an adolescent aged 12 years and 10 months, with a large fistula of the right coronary artery draining into the right ventricular cavity, in which the Amplatzer® Vascular Plug II device was used. The technical steps used […]

ABSTRACT The widespread use of bare metal stents as from 1995 led to the appearance of a new entity called in-stent restenosis, and the severe concomitant calcification of the vessels is a challenge for the interventional cardiologist. In this scenario, rotational atherectomy has rised as a therapeutic rescue approach to manage this situation, using trephines to eliminate the underexpanded and non-expandable coronary stents. However, comprehensive data on the long-term efficacy or results of the procedures have not been published yet. […]

ABSTRACT Myocardial infarction is well described in the COVID-19 pandemic and specific protocols should be developed in the context of acute management of this condition. The relation between myocardial injury and death is well established in the literature and is associated with an increased need for invasive ventilation and other complications. Type 2 myocardial infarction and new onset of heart failure have been diagnosed more frequently in the setting of COVID-19. Particular emphasis should be placed on timing for invasive […]

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.

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 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 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 […]
