Introduction The optimal approach to the extraction of leads with large vegetations remains uncertain. Methods High-risk patients with lead associated vegetations undergoing device extraction at Vanderbilt Hospital with concomitant use of the Penumbra Aspiration System (Penumbra Inc, Alameda, CA) are described. An 8.5 Fr Agilis NXT (Abbott Inc, St. Paul, MN) was advanced to the right atrium, through which a Penumbra Indigo Cat-8 catheter was advanced. Using intracardiac echocardiography, the Penumbra was positioned directly on the vegetation, suction was applied until adherent, and the Indigo catheter and Agilis sheath were then removed en-bloc and aspirated debris flushed out. This was repeated until debulking was considered successful. Results Eight cases were performed. The median vegetation size was 2 cm. Pathogens were Enterococcus, Staphylococcus, Candida, Cutibacterium, and Enterobacter. In seven of eight cases, aspiration successfully reduced vegetations to less than 1 cm before successful percutaneous cardiac implantable electronic device removal. One patient underwent surgical removal via thoracotomy. There were no acute complications related to the Penumbra catheter. Three patients had CT evidence of small pulmonary emboli postprocedure. The length of stay was 3 to 27 days. One patient died on POD 1 of refractory ventricular tachycardia unrelated to the procedure. One patient died of ongoing sepsis 2 weeks postextraction. Conclusions The Penumbra Indigo Aspiration system can be useful for vegetation debulking before transvenous lead extraction.
