Endocarditis infecciosa después de TAVI: aportaciones de la experiencia en un único centro sobre la incidencia y los factores asociados / Infective endocarditis after transcatheter aortic valve implantation: Contributions of a single-centre experience on incidence and associated factors

INTRODUCCIÓN: La endocarditis infecciosa (EI) sobre transcatheter aortic valve implantation (TAVI) es una complicación emergente. Existen datos incompletos y dispares sobre su incidencia. Se aporta la experiencia en nuestro centro sobre incidencia, mortalidad y factores asociados de la EI post-TAVI y se compara con datos de la literatura. MÉTODOS: Estudio retrospectivo observacional de los casos de EI diagnosticados en pacientes que habían recibido TAVI, entre el 1 de junio de 2009 y el 1 de noviembre de 2017, en un centro universitario tras una mediana de seguimiento de 15,3 meses (rango intercuartil [RIC] 9,1-36,2). Se analizaron la incidencia, los datos clínicos, microbiológicos y pronósticos, y los factores asociados a EI post-TAVI. RESULTADOS: Se detectaron 11 pacientes con EI de 200 TAVI. Incidencia global: 5,5% (2,77 casos por 100 años-paciente). La mediana de tiempo hasta la EI post-TAVI fue de 112 días (RIC 36-578), la tasa de mortalidad intrahospitalaria fue del 36,4% y la mortalidad al año, del 54,5%. Todos los microorganismos identificados fueron grampositivos (4 Enterococcus faecalis, 3 Staphylococcus coagulasa negativo). Los pacientes con EI post-TAVI eran significativamente más jóvenes (mediana 78, RIC 73-80, frente a 82, RIC 79-84, p = 0,002), tenían un EuroSCORE mayor (5,1 ± 2,4 frente a 3,2 ± 1,2, p < 0,001) y más frecuentemente antecedentes de neoplasia (18,2% frente al 4,2%, p < 0,03). CONCLUSIONES: En nuestro medio, la incidencia de EI post-TAVI es mayor que la descrita en series multicéntricas, lo que concuerda con la tendencia publicada en la literatura. Conlleva una elevada mortalidad y se asocia con una peor situación clínica basal

INTRODUCTION: Infective endocarditis (IE) after transcatheter aortic valve implantation (TAVI) is an emerging complication. There are incomplete and disparate data on its incidence. We present the experience of a single-centre of incidence, mortality and associated factors of IE after TAVI. METHODS: A retrospective observational study of IE cases in people who received a TAVI, between 06/01/2009 and 11/01/2017, in a university hospital, during a median follow-up period of 15.3months (interquartile range [IQR] 9.1-36.2). Incidence, clinical, microbiological and prognostic data, and factors associated with IE after TAVI were analysed. RESULTS: Eleven patients with IE of 200 TAVI were detected. Global incidence: 5.5% (2.77 cases per 100 patient-year). The median of days from TAVI to IE was 112 (IQR 36-578), the in-hospital mortality rate was 36.4%, and the one-year mortality rate was 54.5%. All the organisms identified were gram-positive (4 Enterococcus faecalis, 3 coagulase-negative Staphylococcus). The patients with IE after TAVI were significantly younger (median 78 years, IQR 73-80, versus 82 years, IQR 79-84, P=.002), they had a higher EuroSCORE (5.1±2.4 versus 3.2 ± 1.2, P < .001), and they more frequently had a history of neoplasia (18.2% versus 4.2%, P < .03). CONCLUSIONS: In our area, IE after TAVI has an incidence greater than that described in multicentre series, this is in line with the trend published in the literature. It leads to high mortality and is associated with a worse baseline clinical situation
