          Abstract

          RESUMEN Introducción y objetivos: La fuga paravalvular (FPV) moderada o grave tras el implante percutáneo de válvula aórtica (TAVI) se ha asociado a peores resultados. La calcificación de la válvula aórtica constituye un importante factor predictivo de FPV. ACURATE neo (Boston Scientific Corporation, Estados Unidos) es una válvula cardiaca transcatéter autoexpandible para el tratamiento de la estenosis aórtica degenerativa. Se evaluó la presencia de FPV tras el implante de ACURATE neo y neo2, así como el papel de la calcificación de la válvula aórtica. Métodos: Se analizaron pacientes intervenidos de TAVI con ACURATE neo y neo2 de un hospital terciario de alto volumen. Todas las tomografías computarizadas cardiacas se analizaron con el software 3Mensio Structural Heart (Pie Medical Imaging, Países Bajos). El volumen de calcio aórtico se cuantificó mediante tomografía computarizada cardiaca con contraste. Se registró prospectivamente la evolución clínica y ecocardiográfica a 30 días. Resultados: Se incluyeron 165 pacientes intervenidos de TAVI con ACURATE (neo = 87; neo2 = 78). La mediana de edad fue de 82 años, el 65% eran mujeres y la mediana de EuroSCORE II fue de 4,7 [rango intercuartílico, 2,4-6,1]. Los pacientes del grupo con neo presentaban una mayor cantidad de calcio total aórtico (320 frente a 200 mm3; p = 0,0305). No se hallaron diferencias significativas entre los grupos en cuanto a los resultados clínicos tanto durante el ingreso como a los 30 días. A los 30 días, la tasa de FPV ≥ leve (61 frente a 34%; p < 0,001) y de FPV ≥ moderada (15,9 frente a 5,4%, p = 0,0365) fue más alta en el grupo con neo. Tras el emparejamiento por puntuación de propensión ajustado por la cantidad total de calcio aórtico, neo2 se relacionó con un menor riesgo de FPV ≥ leve (odds ratio [OR] = 0,35; intervalo de confianza del 95% [IC95%], 0,18-0,69; p = 0,003) y de FPV ≥ moderada (OR = 0,16; IC95%, 0,03-0,74; p = 0,019). Conclusiones: El TAVI con ACURATE neo2, en comparación con neo, se asocia a un menor riesgo de cualquier grado de FPV y a un menor riesgo de FPV ≥ moderada. Tras el ajuste por volumen de calcio aórtico, ACURATE neo2 se asocia a un menor riesgo de FPV.

          ABSTRACT Introduction and objectives: Moderate or severe paravalvular leak (PVL) following transcatheter aortic valve implantation (TAVI) has been associated with worse outcomes. Aortic valve (AV) calcification is a strong predictor of PVL. ACURATE neo (Boston Scientific Corporation, United States) is a self-expanding transcatheter heart valve to treat degenerative aortic stenosis. We evaluated PVL after ACURATE neo and neo2 implantation, and the role of AV calcification. Methods: We analyzed patients referred for TAVI with ACURATE neo and neo2 from a large volume tertiary center. All cardiac computed tomography scans were analyzed using 3Mensio Structural Heart software (Pie Medical Imaging, The Netherlands). The volume of AV calcium was quantified using contrast-enhanced cardiac computed tomography series. The 30-day clinical and echocardiographic data were prospectively recorded. Results: We included 165 patients referred for TAVI with ACURATE (neo = 87; neo2 = 78). Median age was 82 years-old, 65% were women with a median EuroSCORE II of 4.7 [IQR, 2.4-6.1]. Patients in the neo group showed a larger amount of total AV calcium (320 mm3 vs 200 mm3; P =.0305). We found no significant inter-group differences regarding clinical outcomes both in-hospital or at 30-days. At 30-days, the rate of PVL ≥ mild (61% vs 34%; P <.001) and ≥ moderate (15.9% vs 5.4%; P =.0365) were higher in the neo group. After propensity score matching adjusted by the total amount of AV calcium, neo2 was associated with a lower risk of PVL ≥ mild (OR, 0.35, 95%CI, 0.18-0.69; P =.003), and ≥ moderate (OR, 0.16; 95%CI, 0.03-0.74; P =.019). Conclusions: TAVI with ACURATE neo2 vs neo is associated with a lower risk of any degree of PVL and a reduced risk of PVL ≥ moderate. After adjusting for AV calcium volume, ACURATE neo2 was still associated with a lower risk of PVL.

          2020 ACC/AHA Guideline for the Management of Patients With Valvular Heart Disease: Executive Summary: A Report of the American College of Cardiology/American Heart Association Joint Committee on Clinical Practice Guidelines

          This executive summary of the valvular heart disease guideline provides recommendations for clinicians to diagnose and manage valvular heart disease as well as supporting documentation to encourage their use. A comprehensive literature search was conducted from January 1, 2010, to March 1, 2020, encompassing studies, reviews, and other evidence conducted on human subjects that were published in English from PubMed, EMBASE, Cochrane, Agency for Healthcare Research and Quality Reports, and other selected database relevant to this guideline. Many recommendations from the earlier valvular heart disease guidelines have been updated with new evidence and provides newer options for diagnosis and treatment of valvular heart disease. This summary includes only the recommendations from the full guideline which focus on diagnostic work-up, the timing and choice of surgical and catheter interventions, and recommendations for medical therapy. The reader is referred to the full guideline for graphical flow charts, text, and tables with additional details about the rationale for and implementation of each recommendation, and the evidence tables detailing the data considered in developing these guidelines.

            Valve Academic Research Consortium 3: Updated Endpoint Definitions for Aortic Valve Clinical Research

            The Valve Academic Research Consortium (VARC), founded in 2010, was intended to (i) identify appropriate clinical endpoints and (ii) standardize definitions of these endpoints for transcatheter and surgical aortic valve clinical trials. Rapid evolution of the field, including the emergence of new complications, expanding clinical indications, and novel therapy strategies have mandated further refinement and expansion of these definitions to ensure clinical relevance. This document provides an update of the most appropriate clinical endpoint definitions to be used in the conduct of transcatheter and surgical aortic valve clinical research.
