ABSTRACT
Introducción y objetivos: Los tratamientos actuales de la estenosis aórtica (EAo) grave incluyen el implante percutáneo de válvula aórtica (TAVI) y la cirugía de sustitución valvular aórtica (SVAo). El objetivo es describir la evolución de los pacientes con EAo grave tras la indicación de intervención, las variables que influyen en su pronóstico y los determinantes de un tiempo de espera superior a 2 meses. Métodos: Subanálisis del registro IDEAS (Influencia del Diagnóstico de Estenosis Aórtica Severa) en los pacientes a los que se indicó intervención. Resultados: De 726 pacientes con EAo grave diagnosticada en enero de 2014, se indicó intervención a 300 que son el foco del presente estudio. La media de edad era 74,0 +/- 9,7 años. Se intervino a 258 pacientes (86,0%): 59 con TAVI y 199 con SVAo. Al año, 42 (14,0%) continuaban sin intervención, ya sea por seguir en espera (34) o haber fallecido (8). La mitad de los pacientes que murieron antes del procedimiento fallecieron en los primeros 100 días. El tiempo hasta la intervención fue 2,9 +/- 1,6 meses para el TAVI y 3,5 +/- 0,2 meses para la SVAo (p = 0,03). Los predictores de mortalidad independientes fueron el sexo masculino (HR = 2,6; IC95%, 1,1-6,0), la insuficiencia mitral moderada-grave (HR = 2,6; IC95%, 1,5-4,5), la movilidad reducida (HR = 4,6; IC95%, 1,7-12,6) y la falta de intervención (HR = 2,3; IC95%, 1,02-5,03). Conclusiones: Los pacientes con EAo grave en espera de intervención tienen alto riesgo de mortalidad. Hay indicadores clínicos asociados con peor pronóstico que podrían indicar la necesidad de una intervención precoz
Introduction and objectives: Current therapeutic options for severe aortic stenosis (AS) include transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR). Our aim was to describe the prognosis of patients with severe AS after the decision to perform an intervention, to study the variables influencing their prognosis, and to describe the determinants of waiting time > 2 months. Methods: Subanalysis of the IDEAS (Influence of the Severe Aortic Stenosis Diagnosis) registry in patients indicated for TAVI or SAVR. Results: Of 726 patients with severe AS diagnosed in January 2014, the decision to perform an intervention was made in 300, who were included in the present study. The mean age was 74.0 +/- 9.7 years. A total of 258 (86.0%) underwent an intervention: 59 TAVI and 199 SAVR. At the end of the year, 42 patients (14.0%) with an indication for an intervention did not receive it, either because they remained on the waiting list (34 patients) or died while waiting for the procedure (8 patients). Of the patients who died while on the waiting list, half did so in the first 100 days. The mean waiting time was 2.9 +/- 1.6 for TAVI and 3.5 +/- 0.2 months for SAVR (P = .03). The independent predictors of mortality were male sex (HR, 2.6; 95%CI, 1.1-6.0), moderate-severe mitral regurgitation (HR, 2.6; 95%CI, 1.5-4.5), reduced mobility (HR, 4.6; 95%CI, 1.7-12.6), and non intervention (HR, 2.3; 95%CI, 1.02-5.03). Conclusions: Patients with severe aortic stenosis a waiting therapeutic procedures have a high mortality risk. Some clinical indicators predict a worse prognosis and suggest the need for early intervention

CONCLUSIONS: Patients with severe aortic stenosis awaiting therapeutic procedures have a high mortality risk. Some clinical indicators predict a worse prognosis and suggest the need for early intervention.
