Background: Transcatheter aortic valve implantation (TAVI) is a well-established treatment for symptomatic patients with aortic stenosis. Yet, the impact of sex differences and public vs. private procedural setting on TAVI outcomes remain uncertain., Methods: The RIBAC-NT (Brazilian Registry for Evaluation of Transcatheter Aortic Valve Replacement Outcomes) dataset included 3194 TAVI patients from 2009 to 2021. This retrospective analysis explored disparities in baseline characteristics, procedural and in-hospital outcomes stratifying patients by sex and procedural setting. Temporal trends were also investigated., Results: We included 1551 (49 %) female and 1643 (51 %) male patients. Women were older (83 [78-87] vs. 81 [75-85] years; p < 0.01) but had a lower prevalence of diabetes mellitus (30.2 % vs. 36.3 %, p < 0.01) and coronary artery disease (39.0 % vs. 52.2 %, p < 0.01). However, women had a 3-fold higher higher risk of life-threatening bleeding (6.1 % vs. 2.4 %, p < 0.01). Women presented higher procedural and in-hospital mortality rates (4.4 % vs. 2.5 % and 7.7 % vs. 4.5 %, all p < 0.01, respectively). Although public hospitals presented ~2-fold higher procedural mortality rate compared with private settings (5.0 % vs. 2.7 %, p < 0.01), after multivariable analysis procedural setting was not independently associated with in-hospital mortality., Conclusions: Women had higher procedural and in-hospital mortality rates after TAVI as compared with men, while facing higher life-threatening bleeding and adverse events rates. Although public hospitals exhibited higher mortality rates than private centers, procedural setting was not independently associated with in-hospital mortality., Competing Interests: Declaration of competing interest Dr. de Brito has served as proctor for Edwards LifeSciences and Medtronic.

Introduction and Objectives: Acute kidney injury (AKI) is frequently observed after transcatheter aortic valve implantation (TAVI) and is associated with higher mortality. However, the impact of AKI on long-term outcomes remains controversial. Therefore, we sought to evaluate the impact of AKI on short- and long-term outcomes following TAVI using the Valve Academic Research Consortium 2 criteria., Methods: Consecutive patients (n = 794) with severe aortic stenosis who underwent TAVI were included in a multicenter Brazilian registry. Logistic regression analysis was used to identify predictors of AKI. Four-year outcomes were determined as Kaplan-Meier survival curves, and an adjusted landmark analysis was used to test the impact of AKI on mortality among survivors at 12 months., Results: The incidence of AKI after TAVI was 18%. Independent predictors of AKI were age, diabetes mellitus, major or life-threatening bleeding and valve malpositioning. Acute kidney injury was independently associated with higher risk of all-cause death (adjusted HR, 2.8; 95%CI, 2.0-3.9; P < .001) and cardiovascular mortality (adjusted HR, 2.9; 95%CI, 1.9-4.4; P < .001) over the entire follow-up period. However, when considering only survivors at 12 months, there was no difference in both clinical endpoints (adjusted HR, 1.2; 95%CI, 0.5-2.4; P = .71, and HR, 0.7; 95%CI, 0.2-2.1; P = .57, respectively)., Conclusions: Acute kidney injury is a frequent complication after TAVI. Older age, diabetes, major or life-threatening bleeding, and valve malpositioning were independent predictors of AKI. Acute kidney injury is associated with worse short- and long-term outcomes. However, the major impact of AKI on mortality is limited to the first year after TAVI., (Copyright © 2017 Sociedad Española de Cardiología. Published by Elsevier España, S.L.U. All rights reserved.)

Penetrating aortic atherosclerotic ulcer is an underdiagnosed condition that presents high rates of morbidity and mortality. We report two cases of patients with severe chest pain, with no ischemic features, who underwent chest angiotomography and showed an ulceration of the aortic wall, with contrast penetration into the middle layer. Due to the failure of the medical treatment, the patients underwent percutaneous aortic stent implantation with complete resolution of symptoms.

Obstructions of the upper venous system may be due to spontaneous thrombosis or the presence of hemodialysis or chemotherapy catheters, or even the presence of extrinsic compression due to intra-thoracic tumors. The use of endoprosthesis for the treatment of these obstructions has become common practice, and its indications include situations of risk for pulmonary embolism, superior vena cava syndrome, and loss of vascular access. Within this context, the use of intracardiac ultrasound may be useful in evaluating the extension and severity of the obstructive lesion, besides providing important information about the mural and intraluminal morphology of the venous system. The authors report the case of a patient with superior vena cava syndrome caused by thrombosis at the entry pathway of the right atrium, besides discussing the subject by means of literature review.

We report the case of a female patient with obstructive lesions in the right and left carotid, right renal, left subclavian and left common iliac arteries which were percutaneously treated.

Objective: To determine the prevalence of renal artery stenosis (RAS) in patients who have undergone cineangiocoronariography., Methods: Prospective study of cineangiocoronariography and aortography examinations conducted between January 2002 and February 2004 on 1,656 hypertensive and normotensive patients who underwent the examinations to confirm the diagnosis of obstructive coronary artery disease or valve disease., Results: The average age of the 1,656 patients was 61.6 +/- 11.8 years. Eight hundred and ninety-one (53.8%) were male, 169 (10.2%) were diabetic and 1,054 (63.8%) presented obstructive coronary artery disease. Renal stenosis greater than 50% was observed in 228 (13.8%) patients, and 25 (1.5%) had bilateral stenosis. Obstructive coronary artery disease was defined as stenosis greater than or equal to 50% of the vessel lumen, in one, two or three main arteries, classified as single, double or triple vessels, respectively. Quantification was conducted using visual analysis of the angiography. Comparison of the groups with and without renal artery obstruction > or = 50%, revealed significant statistical differences in relation to gender, age, diabetes mellitus, blood pressure and left ventricular function. However, no statistical difference was noted in relation to the occurrence of coronary artery obstructions > or = 50%. Nevertheless, renal artery obstructions > or = 70%, revealed significant differences in relation to blood pressure, coronary artery obstructions > or = 50% and left ventricular function, which were all higher in the renal artery obstruction group., Conclusion: The prevalence of RAS found in our study was comparable to that reported by major medical literature case studies. RAS is associated with systemic hypertension (SH), end-stage renal disease (ESRD) and its sequelae, emphasizing how important it is that we are aware of possible candidates for angiographic diagnosis of this disease.

We report the case of a 16-year-old pregnant patient with severe aortic stenosis and pulmonary congestion clinically uncontrolled, in whom percutaneous balloon aortic valvuloplasty was used as the first choice of treatment in an emergency procedure. The clinical findings, pathophysiology, diagnostic features, and indications for percutaneous treatment are reported. Severe congenital aortic stenosis is rare in children and young individuals. Bicuspid aortic valve occurs in 3% to 6% of patients with congenital heart disease; when associated with commissural fusion, significant stenosis may be present in childhood. The association of severe congenital aortic stenosis and pregnancy is difficult to control clinically, carrying a high risk of maternal and fetal mortality, mainly when manifested with symptoms of pulmonary congestion 1,2.
