Two cases of aneurysm of the anterior mitral valve leaflet associated with transcatheter aortic valve endocarditis: a mere coincidence?

The incidence of transcatheter aortic valve endocarditis (TAVE) is currently unknown. To the best of our knowledge, 2 clinical case reports of TAVE have been published (1 Edwards SAPIEN [Edwards Lifesciences, Irvine, Calif] and 1 Medtronic CoreValve ReValving System [Medtronic CV, Luxembourg Sarl]). [1] and [2] Interestingly, both cases were associated with aneurysm and perforation of the anterior mitral valve leaflet—a link that has not been previously reported. We briefly review the clinical presentations of these cases and discuss the possible implications of endocarditis in the context of transcatheter aortic valve implantation.
