Endocarditis of amplatzer^® occluder devices after percutaneous closure of a mitral paravalvular leak

Abstract

Symptomatic paravalvular leaks (PVL) are a relatively uncommon, but potentially significant postoperative complication of valve replacement surgery. Percutaneous repair of PVLs has become an increasingly utilized approach in patients whose comorbidities obviate surgical repair. We present an interesting case of a gentleman who underwent successful repair of a mitral PVL with Amplatzer devices following initial aortic and mitral valve replacements for bacterial endocarditis. He later developed fungal endocarditis that ultimately required re-operation to remove the devices and replace his mitral and aortic valves. This complication of closure devices, although reportedly rare, should be considered when contemplating a percutaneous approach. © 2012 Wiley Periodicals, Inc.

Late infective endocarditis of an Amplatzer atrial septal device twelve years after implantation

“…prezentujú nárast IE spôsobenej Staphylococcus aureus počas dvoch dekád z 2 % (1990) na 25 % (2009) [16]. Kazuistiky zamerané na IE okluzorov prezentujú hubovú endokarditídu v dvoch prípadoch, zatiaľ čo v iných siedmich prípadoch považujú za etiologického činiteľa baktérie [8,9,[17][18][19][20][21][22][23]. Tri práce prezentujú pozitivitu hemokultúr na Staphylococcus aureus [9,[21][22].…”

“…Omnoho viac autorov však poukazuje na nutnosť chirurgickej intervencie pri IE implantovaných materiálov. [18,19,[21][22][23]. Vo všeobecnosti približne polovica pacientov s IE vyžaduje chirurgickú intervenciu [26].…”
