Procedural/clinical success, failure, and complications
The success of TLE was determined through complete procedural and
clinical criteria. Complete procedural success was defined as the
removal of all targeted leads and lead material from the vascular space
without permanently disabling complication or procedure-related
mortality. Clinical success was defined as the removal of all
targeted leads and lead material from the vascular space or retention of
a small portion of the lead (<4 cm) that does not negatively
impact the outcome goals of the procedure. This might be the tip of the
lead or a small part of the lead when the remaining portion does not
increase the risk of perforation, embolic events, the perpetuation of
infection or cause any undesired outcome. “Failure” was defined
as the inability to achieve either complete procedural or clinical
success or the development of any permanently disabling complication or
procedural-related death. Complications were defined as major orminor , according to previously published guidelines1.
