Complicaciones del implante de marcapaso definitivo: ?Un evento operador dependiente? Análisis de 743 pacientes consecutivosKeywords: pacemakers, complications, electrical stimulation, argentina. Abstract: the complications of permanent pacemaker implant, are found among 6%-9% of patients. different factors are related. objectives: we evaluated the complications related with pacemaker implants and which are the independent risk factors associated with them. methods: descriptive analysis, type case-controls, retrospective and prospective, including 743 consecutive patients, between january 2007 and april 2008. results: age: 73.83 ± 12 years, 63.9% male. 43% of the patients had some degree of structural cardiopathy. there were no deaths related to pacemaker implants. implant procedure-related complications were observed in 57 patients (7.67%), requiring a surgical intervention in 34 patients (4.57%). the most serious complications included one device-related infective endocarditis (0.13%), the entire device system was extracted, and one pneumothorax following subclavian vein puncture with insertion of a chest tube. in the multivariate analysis, low level of operator experience and preimplant heart failure were independent predictors for complications. conclusions: in this consecutive series of patients with permanent pacemaker implant, there was a low rate of complications, similar to the reported international series. a low level of operator experience and preimplant heart failure were related.
