Surgical Removal of Entrapped Endocardial Leads Without Using Extracorporeal Circulation

Of 267 patients having a tined endocardial lead implanted from 1978 to December 1983, three (1.1%) developed pulse generator pocket infection. Proper treatment of this complication involves removal of the pulse generator, continued external pacing via the implanted lead, pocket drainage and administration of specific antibiotics until the infected area clears. In two patients, the electrode could not be removed by traction. A sternotomy was performed, the pericardium was opened, the endocardial electrode was located by palpation, and a purse string suture (PSS) was prepared around it on the right ventricular wall. A new myocardial electrode with its corresponding generator was then implanted to reestablish pacing. Through the PSS the myocardium was incised, the distal end of the endocardial lead was exteriorized and severed, and the PSS was tied. The remaining lead was withdrawn proximally and the surgical wounds were closed. The results of this procedure have been been excellent, allowing the removal of the entrapped leads, with continuous pacing and without the need for extracorporeal cir culation.

Características clínicas, predictores de mortalidad y resultados Inmediatos y a largo plazo en el tratamiento con angioplastía primaria del infarto agudo al miocardio con supradesnivel del ST complicado con shock cardiogénico

El shock cardiogenico (SC) es la complicacion mas grave del infarto agudo al miocardio (IAM). La mortalidad del SC varia entre un 40-60%. Con el acceso a la angioplastia primaria, el pronosti-co del SC ha mejorado en los ultimos anos, aunque la mortalidad permanece elevada. Nuestro objetivo fue analizar las caracteristicas clinicas, predictores de mor-talidad intrahospitalaria y a largo plazo de los pacientes con IAM complicados con SC en 3 centros hospitalarios con disponibilidad de hemodinamia de urgencia las 24 horas del dia.
