The 2014 American College of Cardiology (ACC)/American Heart Association (AHA) guidelines classified this “paradoxical” LF/LG entity as a D3 stage of aortic stenosis, which is defined as an aortic valve area (AVA) of <1.0 cm 2, an indexed AVA of <0.6 cm 2 /m 2, a mean gradient of <40 mm Hg, a LVEF of >50%, and a stroke volume index (SVi) of ...
17 de dic. de 2020 · Stage D1 reflects patients with high-gradient symptomatic AS (V max ≥4.0 m/s, mean gradient ≥40 mm Hg, aortic valve area [AVA] ≤1.0 cm 2 ); Stage D2 reflects low-flow, low-gradient severe AS with reduced LVEF (AVA ≤1.0 cm 2, V max <4.0 m/s or mean gradient <40 mm Hg, LVEF <50%); and Stage D3 reflects low-flow, low-gradient severe AS with normal ...
Supplemental calcium with or without vitamin D is associated with lower survival and greater aortic valve replacement in elderly patients with mild to moderate aortic stenosis. How might this impact on clinical practice?
En pacientes sintomáticos con EA grave (estadio D1, velocidad aórtica ≥4,0 m / seg gradiente de presión medio ≥40 mmHg), la prueba de esfuerzo no debe realizarse debido al riesgo de compromiso hemodinámico grave. (Recomendación 3: Sin beneficio - B-NR).
23 de ago. de 2021 · Aortic stenosis is the most common heart valve disease necessitating surgical or percutaneous intervention. Imaging has a central role for the initial diagnostic work-up, the follow-up and the selection of the optimal timing and type of intervention.
15 de abr. de 2015 · The ACC/AHA guidelines recommend aortic valve replacement (AVR) as a Class IIa (Level of Evidence: C) recommendation in D3 AS patients: "AVR is reasonable in symptomatic patients who have low-flow, low-gradient severe AS who are normotensive and have a LVEF ≥50% if clinical, hemodynamic, and anatomic data support valve obstruction ...
6 de mar. de 2019 · Low flow low gradient (LFLG) severe aortic stenosis (stages D2 and D3) represents an advanced stage in the hemodynamic spectrum of severe AS with poor prognosis and higher surgical morbidity and mortality than normal flow high gradient severe AS [8, 9, 10, 11, 12].
