Percutaneous transeptal mitral valve endocarditis debulking with AngioVac aspiration system.

Vacuum assisted aspiration with the AngioVac system has been well described for; right sided endocarditis, venous thrombus, lead related infection/thrombus aspiration and right sided cardiac mass evacuation. Percutaneous transeptal debulking with AngioVac for mitral valve endocarditis (MVE) in the inoperable or high surgical risk patient has not been well defined. A significant proportion of high/prohibitive surgical risk patients with left sided infective endocarditis (IE) are not offered valve surgery as patients in the acute active phase of IE have a high surgical mortality. Nonetheless, sequala of acute IE ie stroke, sepsis or hemodynamic instability in itself is associated with high morbidity and mortality without surgical treatment. A case report of an inoperable patient with methicillin sensitive staphylococcus aureus MVE who was offered MV vegetation debulking with the AngioVac Gen3 C 180 MV system is described. Preprocedural planning with attention to; optimal transeptal height puncture, use of sentinel cerebral protection device to decrease risk of procedure related cerebral embolism and venous extracorporeal membrane cannula, rather than arterial cannula for reinfusion, is described to avoid large bore arterial access related vascular complications. Further studies in a randomized manner are warranted to test these procedural techniques and determine outcomes of percutaneous aspiration of left sided IE with the AngioVac system in this highrisk inoperable cohort of patients.
