Abstract This consensus of nomenclature and classification for congenital bicuspid aortic valve and its aortopathy is evidence-based and intended for universal use by physicians (both pediatricians and adults), echocardiographers, advanced cardiovascular imaging specialists, interventional cardiologists, cardiovascular surgeons, pathologists, geneticists, and researchers spanning these areas of clinical and basic research. In addition, as long as new key and reference research is available, this international consensus may be subject to change based on evidence-based data1.

The ISCHEMIA trial revisited: setting the record straight on the benefits of coronary bypass surgery and the misinterpretation of a landmark trial.

OBJECTIVES: The ISCHEMIA trial is a landmark study that has been the subject of heated debate within the cardiovascular community. In this analysis of the ISCHEMIA trial, we aim to set the record straight on the benefits of coronary artery bypass grafting (CABG) and the misinterpretation of this landmark trial. We sought to clarify and reorient this misinterpretation. METHODS: We herein analyse the ISCHEMIA trial in detail and describe how its misinterpretation has led to an erroneous guideline recommendation downgrading for prognosis-altering surgical therapy in these at-risk patients. RESULTS: The interim ISCHEMIA trial findings align with previous evidence where CABG reduces the long-term risks of myocardial infarction and mortality in advanced coronary artery disease. The trial outcomes of a significantly lower rate of cardiovascular mortality and a higher rate of non-cardiovascular mortality with the invasive strategy are explained according to landmark evidence. CONCLUSIONS: The ISCHEMIA trial findings are aligned with previous evidence and should not be used to downgrade recommendations in recent guidelines for the indisputable benefits of CABG.

Encuesta multinacional y transversal sobre las controversias del reemplazo de la raíz aórtica con conservación valvular / Multinational and Cross-Sectional Survey on Valve-Sparing Aortic Replacement Controversies

RESUMEN Introducción : El reemplazo de la raíz aórtica con conservación valvular (valve-sparing aortic root replacement, VSAR) se ha consolidado como un procedimiento eficaz para el tratamiento del aneurisma de la raíz aórtica, el síndrome de Marfan, la válvula bicúspide y la disección aórtica. Sin embargo, es necesario llegar a una opinión unánime sobre los aspectos clave del VSAR. Material y métodos : Se realizó una revisión bibliográfica de los debates y controversias más frecuentes del VSAR. A partir de esta información se elaboró una encuesta en línea que se envió a cirujanos con experiencia comprobada en VSAR para conocer su opinión sobre los factores relacionados con los pacientes, los aspectos técnicos, la ecocardiografía, la investigación, la formación y el futuro del VSAR. Resultados : Veinte cirujanos completaron la encuesta. Según 14 de cada 20 encuestados, la fracción de eyección grave se consideró una contraindicación para el llevar a cabo este procedimiento. El límite del diámetro del anillo aórtico para la remodelación fue heterogéneo entre los participantes. Todos ellos consideraron que el VSAR es un procedimiento seguro para los pacientes con síndrome de Marfan y válvula bicúspide. En el caso de disección de tipo A, 11 de cada 20 prefirieron este procedimiento solo para los pacientes jóvenes. En lo que respecta al tamaño del injerto, la altura del triángulo intervalvar (8/20) y el diámetro sinotubular (7/20) fueron los más frecuentes. Los cirujanos informaron una tasa de fracaso del 7% en la conversión al procedimiento de Bentall, y un cambio de estrategia intraoperatoria del 26%. No se consideró que un abordaje mínimamente invasivo mejorara los resultados. La mayoría de los cirujanos coincidieron en que el VSAR lo deben realizar cirujanos con mucha experiencia. Conclusiones : El VSAR ha sido aceptado como una opción terapéutica para el aneurisma de la raíz aórtica, y, aunque todavía no es posible llegar a un consenso definitivo, se presenta la valiosa experiencia de los cirujanos más destacados en este campo.

ABSTRACT Background : The valve-sparing aortic root replacement (VSAR) has been established as a successful procedure for aortic root aneurysms, Marfan's syndrome, bicuspid valves, and aortic dissections. However, there is a need for a consensus opinion regarding key aspects of VSAR. Methods : A literature review was performed regarding the most frequent debates and controversies in VSAR. An online survey was developed based on this information, and sent to surgeons with known expertise in VSAR regarding their opinion on patient-related factors, technical aspects, echocardiography, research, training, and the future of VSAR. Results : Twenty surgeons completed the survey. The reduction of left ventricular ejection fraction was considered a contra indication to VSAR when severe by 14/20 surveyed. The aortic annulus diameter cutoff point for the remodeling was heterogenous among participants. All of them felt that VSAR is safe for the Marfan´s syndrome population and bicuspid valves. For type A dissections, 11/20 preferred this procedure only in young patients. Regarding to graft sizing, the height of the interleaflet triangle (8/20) and the sino-tubular diameter (7/20) were the more frequent considered parameters. Surgeons reported a 7% of failure rate, leading to conversion to Bentall surgery, and a 26% change of strategy intraoperatively. A minimally invasive approach was not considered to improve results. Most of the surgeons agreed that VSAR should be performed by high-experienced surgeons. Conclusions : The VSAR has been accepted as a treatment option for the aortic root´s aneurysms, and even though there is still not possible to reach a final consensus, a valuable experience from the most relevant surgeons in the field is presented.

Standardized definition of structural valve degeneration for surgical and transcatheter bioprosthetic aortic valves

ABSTRACT: Bioprostheses are prone to structural valve degeneration, resulting in limited long-term durability. A significant challenge when comparing the durability of different types of bioprostheses is the lack of a standardized terminology for the definition of a degenerated valve. This issue becomes especially important when we try to compare the degeneration rate of surgically inserted and transcatheter bioprosthetic valves. This document, by the VIVID (Valve-in-Valve International Data), proposes practical and standardized definitions of valve degeneration and provides recommendations for the timing of clinical and imaging follow-up assessments accordingly. Its goal is to improve the quality of research and clinical care for patients with deteriorated bioprostheses by providing objective and strict criteria that can be utilized in future clinical trials. We hope that the adoption of these criteria by both the cardiological and surgical communities will lead to improved comparability and interpretation of durability analyses.
