Literature - the registry enrolled 504 patients (mean age 66.6 6 12.8 years; 65.7% male).Complete procedural success was achieved in 474 patients (94.0%) and clinical success in 492 patients (97.6%).The total number of major and minor complications was 16 (3.2%) and 51 (10%), respectively.Three patients (0.6%) died during the procedure.New york heart association functional class iv and c-reactive protein levels defined before the procedure were independent predictors of any major complication, including death in 30 days in cied infection patients.The time since the last preceding procedure and platelet count before the procedure were independent predictors of any major complication, including death in 30 days in non¿cied infection patients.Literature - complete procedural success was achieved in 474 patients (94.0%) and clinical success in 492 (97.6%).All targeted leads were extracted in 478 patients (94.8%).In 14 patients (2.8%), a small part of the lead (<4 cm) was left in place.Failure of the procedure occurred in 30 patients (6.0%).The crucial cause of procedural and clinical failure was the presence of lead fragments (>4 cm) in 12 patients (2.4%).There were significant differences between cied infection and non¿cied infection patients in achieving clinical success (99.3% vs 96.6%; p 5.02) and complete procedural success (97.4% vs 92.6%; p 5.04).Three patients from the cied infection group underwent gladysz-wa_nha et al lead extraction in patients with and without infections 3 incomplete lead extraction (<4 cm of the lead left in place), which had no negative impact on the course of the infection (figure 2).The most frequent minor complication was venous thrombosis in 19 patients (3.8%), which occurred significantly more often in non¿cied infection patients (5.1% vs 0.7%; p 5.02).Four cases of pericardial effusion with no need for intervention occurred in non¿cied infection patients and none in the cied infection group.Twelve patients died up to 30 days after the procedure, 10 in the cied infection group and 2 in non¿cied infection (p 5.0001).Two patients with non¿cied infection indications for tle with right ventricular lead dysfunction resulting in abnormalities of impedance and capture and 1 patients with isolated pocket erosion with purulent drainage died during the procedure because of superior vena cava injury (n 5 3 [0.6%]).The dwell time of those extracted leads was >10 years.Nine patients (1.8%) died up to 30 days after the procedure because of postoperative management issues of underlying diseases (eg, sepsis or heart failure).The most frequent major complication, excluding death, was pericardial effusion requiring open heart surgery in 10 patients.The frequency of occurrence did not differ between the 2 groups (p 5.16) (table 4).
