Why the study?
The study was conducted to estimate the impact of the organisational model of transvenous lead extraction on procedural effectiveness and safety.
Does the organisational model (including cardiac surgery backup and TEE monitoring) improve the effectiveness and safety of transvenous lead extraction?
Does the organisational model (including cardiac surgery backup and TEE monitoring) improve the effectiveness and safety of transvenous lead extraction?
Continuous TEE monitoring and close cooperation with a cardiac surgery team improve procedural success and prevent mortality from major complications during transvenous lead extraction.
Close cardiac surgery cooperation and TEE monitoring may enhance TLE safety and success; supports guidelines but leaves open need for prospective confirmation.
OBJECTIVES: To estimate the impact of the organisational model of transvenous lead extraction (TLE) on effectiveness and safety of procedures. DESIGN: Post hoc analysis of patient data entered prospectively into a computer database. SETTING: Data of all patients undergoing TLE in three centres in Poland between 2006 and 2021 were analysed. PARTICIPANTS: 3462 patients including: 985 patients undergoing TLE in a hybrid room (HR), with cardiac surgeon (CS) as co-operator, under general anaesthesia (GA), with arterial line (AL) and with transoesophageal echocardiography (TEE) monitoring (group 1), 68 patients-TLE in HR with CS, under GA, without TEE (group 2), 406 patients-TLE in operating theatre (OT) using 'arm-C' X-ray machine with CS under GA and with TEE (group 3), 154 patients-TLE in OT with CS under GA, without TEE (group 4), 113 patients-TLE in OT with anaesthesia team, using the 'arm-C' X-ray machine, without CS (group 5), 122 patients-TLE in electrophysiology lab (EPL), with CS under intravenous analgesia without TEE and AL (group 6), 1614 patients-TLE in EPL, without CS, under intravenous analgesia without TEE and AL (group 7). KEY OUTCOME MEASURE: Effectiveness and safety of TLE depending on organisational model. RESULTS: The rate of major complications (MC) was higher in OT/HR than in EPL (2.66% vs 1.38%), but all MCs were treated successfully and there was no MC-related death. The use of TEE during TLE increased probability of complete procedural succemss achieving about 1.5 times (OR=1.482; p<0.034) and were connected with reduction of minor complications occurrence (OR=0.751; p=0.046). CONCLUSIONS: The most important condition to avoid death due to MC is close co-operation with cardiac surgery team, which permits for urgent rescue cardiac surgery. Continuous TEE monitoring plays predominant role in immediate decision on rescue sternotomy and improves the effectiveness of procedure.
