AngioVac Debulking in Endocarditis Patients with Large, Device-related Vegetations.

As the number and complexity of cardiovascular implantable electronic devices has increased, so too has the incidence of device-related infections. Such a rise requires that the focus be directed toward developing universal standards for infected lead removal. To date, no consensus currently exists regarding the optimal management of patients with large vegetations (diameter > 2 cm). In these individuals, medical therapy is universally ineffective and they are often too ill for surgical extraction; furthermore, transvenous lead extraction (TLE) carries with it a risk of large septic pulmonary emboli. We present a series of five cases in which the AngioVac thrombectomy system (AngioDynamics Inc., Latham, NY, USA) was used as an adjunct to TLE. Debridement of infected leads prior to percutaneous lead extraction was accomplished as either a bridge to or as concomitant therapy with laser lead removal at our institution. This study included three males and two females with an average age of 52 years. The sizes of vegetations removed from leads ranged from 1.5 cm to 3.9 cm in the largest dimension and the average diameter was 2.65 cm ± 1.1 cm. The vegetations were successfully debulked in all five patients. This suggests that TLE performed with assistance from the AngioVac system (AngioDynamics Inc., Latham, NY, USA) is a safe and effective alternative to open surgical lead removal in patients with large lead vegetations.
