Clinical utility of routine use of continuous transesophageal echocardiography monitoring during transvenous lead extraction procedure

摘要: Background Data on the use of transesophageal echocardiography (TEE) during transvenous lead extraction (TLE) procedures are scarce. Objective The purpose this study was to assess routine TEE extraction. Methods From January 2009 2014, TLE 241 leads in 168 patients (mean age 70 ± 13 years, 129 male, left ventricular ejection fraction 37% 13%) performed. Indication for dysfunction (56.5%), upgrade (27.0%), infection (13%), or other (3.1%). techniques combined a mechanical approach amended by laser technique if required. Extraction were performed with under general anesthesia continuous invasive arterial blood pressure and monitoring. Results possible all except 1 patient. images different projections acquired stored before immediately after each lead. complete 236 (97.9%); 4 distal tips (1.7%) remained situ, dual-coil implantable cardioverter-defibrillator electrode (0.4%) could not be removed. New findings observed 7 161 cases (4.3%): pericardial effusion (mild [2.5%] severe [0.6%]) worsening tricuspid valve insufficiency (2 [1.2%]). only case occurred laceration superior vena cava, which required immediate rescue surgery (0.6%, confidence interval 0.01–3.3). In cases, did entail diagnostic therapeutic measures. Conclusion produced necessitating measures 0.6% suggesting limited utility monitoring TLE.
