Infective Endocarditis after Transcatheter Aortic Valve Implantation

Résumé fourni par la source

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.
