Abstract

Background - We aimed to determine the incidence, predictors, clinical characteristics, management, and outcomes of infective endocarditis (IE) after transcatheter aortic valve implantation (TAVI). Methods and Results - This multicenter registry included 53 patients (mean age, 79±8 years; men, 57%) who suffered IE after TAVI of 7944 patients after a mean follow-up of 1.1±1.2 years (incidence, 0.67%, 0.50% within the first year after TAVI). Mean time from TAVI was 6 months (interquartile range, 1-14 months). Orotracheal intubation (hazard ratio, 3.87; 95% confidence interval, 1.55-9.64; P=0.004) and the self-expandable CoreValve system (hazard ratio, 3.12; 95% confidence interval, 1.37-7.14; P=0.007) were associated with IE (multivariate analysis including 3067 patients with individual data). The most frequent causal microorganisms were coagulase-negative staphylococci (24%), followed by Staphylococcus aureus (21%) and enterococci (21%). Vegetations were present in 77% of patients (transcatheter valve leaflets, 39%; stent frame, 17%; mitral valve, 21%). At least 1 complication of IE occurred in 87% of patients (heart failure in 68%). However, only 11% of patients underwent valve intervention (valve explantation and valve-in-valve procedure in 4 and 2 patients, respectively). The mortality rate in hospital was 47.2% and increased to 66% at the 1-year follow-up. IE complications such as heart failure (P=0.037) and septic shock (P=0.002) were associated with increased in-hospital mortality. Conclusions - The incidence of IE at 1 year after TAVI was 0.50%, and the risk increased with the use of orotracheal intubation and a self-expandable valve system. Staphylococci and enterococci were the most common agents. Although most patients presented at least 1 complication of IE, valve intervention was performed in a minority of patients, and nearly half of the patients died during the hospitalization period.
