We report a case of effective trans catheter repositioning of an ICD lead that was displaced during a trans venous extraction procedure of another malfunctioning ICD lead. This original technique was effective also in screwing-in the active fixation tip of the lead. Skilled operators could take into account this technique to avoid the re-opening of the device pocket, when dealing with specific situations at high risk of infection. ventricular ejection fraction. No other relevant comorbidities were known.The patient presented to our attention with two leads: the abandoned dual-coil lead and the single-coil malfunctioning lead (Kainox RV-S 75, Biotronik, Berlin, Germany), that was targeted for TLE ( Figure 1A). The indication for TLE raised after evidence of significantly decreased shock impedance, from the chronic values around 65 Ohm, to 29 Ohm. Lead dwelling time was twelve years and a procedure of TLE with concomitant new system implantation was planned under general anesthesia.Fibrous adherences in the venous tree were very robust. Singlesheath mechanical dilatation from left subclavian venous entry side in superior vena cava, right atrium (RA) and ventricle (RV) was really challenging. During dilatation, the lead was broken in several points and its remaining extravascular portion was minimal. We decided to cross over to an internal transjugular approach. A deflectable diagnostic catheter was advanced from the left femoral vein and used to grasp the lead in the RA; at this point, the lead was completely intravascular and was then exteriorized from the right internal jugular vein, using two Lasso catheters to catch its externalized cables [1,2].
Case PresentationA 74-years-old male patient was referred to our Institution for transvenous extraction (TLE) of a malfunctioning defibrillator (ICD) lead. Patient's clinical history reported a previous episode of aborted sudden cardiac death, occurred two years after an anterior acute myocardial infarction and a subsequent surgical revascularization. After resuscitation, the patient underwent coronary angiography, which showed no possibility offurther percutaneous or surgical revascularization. A single-chamber ICD system was implanted. Three years later, the occurrence of inappropriate shocks revealed a lead malfunction, unsuccessfully treated with extraction: the lead was abandoned and a new one was implanted. In the follow-up, the patient presented appropriate ICD shocks, despite a 50% left
005Given the long duration of the procedure and the infection risks, we decided to perform the new system implantation at this point, using the same subclavian venous access and left prepectoral pocket. A new single-coil ICD lead with active fixation mechanism was implanted; its tip was screwed-in to the distal portion of the interventricular septum ( Figure 1B). The new lead was then connected to a new single-chamber ICD and the pocket was closed and sutured. Then we proceeded to complete the TLE procedure.The mechanical dilatation from right internal jugular vein w...
