Introduction The prevalence of tricuspid regurgitation (TR) increases with age, concomitant left-side heart disease, and chronic atrial fibrillation. Moderate or severe TR is associated with excess mortality and poor outcomes. The interventional treatment of choice is tricuspid valve repair, with a prosthetic ring capable of reducing the tricuspid annulus diameter, improving valve leaflet coaptation, and correcting regurgitation. Valve replacement is reserved for patients who do not have anatomical conditions for repair. However, an isolated surgical approach to the tricuspid valve […]

Introdução A estenose aórtica degenerativa afeta atualmente 2% a 5% dos adultos com mais de 65 anos, tendo se tornado um problema de saúde pública mundial nas últimas décadas. No Brasil, a prevalência de doença valvar aórtica calcificada aumentou 201,8% de 1990 para 2019, refletindo o envelhecimento da população.O implante valvar aórtico transcateter (TAVI) surgiu como opção para reduzir a mortalidade dos pacientes portadores de estenose aórtica inoperáveis e de alto risco cirúrgico.– Embora diversos estudos clínicos tenham tido importante […]

Introduction Degenerative aortic stenosis, which currently afects 2% to 5% of adults over 65 years of age, has become a public health problem worldwide in recent decades. In Brazil, the prevalence of calcific aortic valve disease increased by 201.8% from 1990 to 2019, reflecting population aging.Transcatheter aortic valve implantation (TAVI) has appeared as an option to reduce mortality in patients with aortic stenosis in whom surgery would be difficult or risky.– Although several clinical studies have played an important role […]

Surgical procedures for replacing body structures through prostheses are perhaps the medical interventions that require great expertise and continuous monitoring, prolonging the lives and health of countless people. This was a theme of the research entitled “ Clinical Features and Survival Analysis of Patients after Mechanical Heart Valve Replacement, with an Emphasis on Prosthetic Valve Thrombosis ” by Tagliari et al. published in volume 119, number 5 of this journal. Among the various contributions the study brings us, some findings […]

Abstract Background: Valvular heart diseases are highly prevalent in the world, and surgical valve replacement has improved patients’ survival. Objectives: To describe clinical and laboratory data of patients undergoing mechanical valve replacement, and to determine the incidence of prosthetic valve thrombosis (PVT). Methods: Retrospective cohort study with a follow-up of up to nine years. The study variables were collected from conventional and electronic medical charts. Statistical calculations were performed using the Jamovi software version 1.2.2.; a p

Abstract Background Conduction disturbances (CD) are the most frequent complication after transcatheter aortic valve replacement (TAVR), and there continues to be a lack of consensus on their management. Objective To assess new CD and permanent pacemaker (PPM) implantation after TAVR and to evaluate the ventricular pacing percentage (VP) up to 1 year of follow-up. Methods Patients who underwent TAVR from October 2014 to November 2019 were enrolled; patients with previous PPM were excluded. Clinical, procedure, ECG, and PPM data were […]

Abstract Background: C-reactive protein (CRP) is an inflammation biomarker that can be a predictor of adverse events in cardiovascular procedures. Its use in the assessment of long-term prognosis of transcatheter aortic valve implantation (TAVI) is still incipient. Objective: To evaluate CRP as a prognostic marker in the first year after TAVI in aortic stenosis (AoS). Methods: CRP was assessed on the first postoperative week in a retrospective cohort of patients with AoS. Pre- and post- CRP levels were correlated with […]

Heart valve disease currently occupies the spotlight in cardiovascular medicine due to recent advances in imaging techniques and emerging therapeutic possibilities, attracting the attention of physicians, researchers, device manufacturers, and investors. Brazil has a prominent international role in the history and technological development of prosthetic heart valves used to treat this disease. The first worldwide implantation of a commercially available porcine valve bioprosthesis occurred in October 1968. About half a century later, in September 2019, passes on the physician and […]

Abstract Background: Balloon post-dilatation (BPD) is often needed for optimizing transcatheter heart valve (THV) implantation, since paravalvular leak (PVL) after transcatheter aortic valve implantation is associated with poor outcome and mortality. Quantitative assessment of PVL severity before and after BPD is mandatory to properly assess PVL, thus improving implantation results and outcomes. Objective: To investigate a quantitative angiographic assessment of aortic regurgitation (AR) by videodensitometry before and after BPD. Methods: Videodensitometric-AR assessments (VD-AR) before and after BPD were analysed in […]
