SUCCESS AND OUTCOMES
The Heart Rhythm Society 2017 consensus document was used to define procedural success and outcome 10. Complete procedural success was defined as removal of all targeted leads and all lead material from the vascular space, with the absence of any permanently disabling complication or procedure related death. Clinical success was regarded as removal of all targeted leads and lead material from the vascular space with the exception of small portion (<4 cm) retention of the lead that does not negatively impact the outcome goals of the procedure including perforation, embolic events or infection perpetuation, etc. Partial success was defined as clinical success when most of the lead was removed, leaving at the most 4 cm of coil and/or insulation and/or lead tip.
Complications were classified using the 2017 HRS conventional criteria10 and were attributed to the extraction method used at the time the complication was observed. Complications were continuously recorded until hospital discharge. Major complications were those that imposed immediate life threat and included procedure-related death, need for pericardiocentesis, vascular tear, severe tricuspid regurgitation (TR) (defined as either TR requiring intervention, or TR resulting in lifelong disability), stroke or requirement of urgent surgery occurring during the TLE procedure. Complications that did not meet the major complication criteria were classified as minor complications.
All-cause mortality and current patient status were updated from Israel’s national population registry updated on a regular basis.
