Background: Infective endocarditis (IE) after transcatheter aortic valve implantation (TAVI) is a rare complication with high morbidity and mortality. Methods: Of 630 consecutive patients undergoing TAVI, 6 (0.95%) presented IE. Results: Four patients were men, mean age was 81.3 ± 2.2 years and all the patients were symptomatic. Left ventricular ejection fraction (LVEF) was 56.8 ± 5.3%. The procedure was successful in all the patients and one presented moderate regurgitation. Two patients required definitive pacemaker and the lead had to be reimplanted 24 hours later in 1 patient. Time to IE was 63.5 ± 73.3 days (median 35 days). A Gram-positive coccus was isolated in four cases. One patient presented a vegetation on transesophageal echocardiography . One patient died within 30 days. During follow-up of 23 ± 22 months none of the patients presented new events or hospitalizations. On Doppler echocardiography, LVEF was 55.9 ± 4.6%, mean trans-aortic gradient was 8.2 ± 1.8 mm Hg and peak systolic velocity was 1.8 ± 0.2 m/s. One patient had moderate regurgitation. Conclusions: In this series of patients, IE after TAVI was uncommon and had a favorable course with antibiotic treatment.
