The Model 3930M family of leads are intended for use in the right ventricle (RV) or for placement in the left bundle branch area as an alternative to right ventricular stimulation sensing, pacing, cardioversion, and defibrillation when a cardiac implantable electronic device is indicated to treat patients who have experienced, or are at significant risk of developing, life-threatening tachyarrhythmias.
This includes adolescent pediatric patients who are at least 30 kg and are also at least 12 years of age, and whose cardiac anatomy is conducive to RV coil placement.
The Model 3930M family of leads are contraindicated for use in the following situations:
Handling the lead – Handle the lead with care at all times. Do not implant the lead if it is damaged. Do not attempt to straighten or realign the helix if the helix is deformed. Return the lead to your Medtronic representative in either event.
Repositioning or removal of an acute lead – Successfully repositioning the lead depends on recreating the angle and advancement of the catheter present at the time of initial helix deployment at implant (relative to the lead helix and endocardium). Proper orientation helps transfer torque to the helix. This increases the likelihood of successfully disengaging the helix from the endocardium. Improper removal of the lead by pulling may result in avulsion of the endocardium.
Extraction or removal of a chronic lead – Proceed with caution if a chronically implanted lead must be removed or extracted. Lead extraction procedures should be consistent with the most recent editions of HRS or EHRA expert consensus statements regarding cardiovascular implantable electrode device lead management and extraction. Market released extraction tools or clinically recognized techniques may be used to help facilitate extraction. When the risk of lead extraction outweighs the benefit, it may be preferable to abandon unused leads and leave in place. Return all removed leads, unused leads, or lead sections to Medtronic for analysis.
Connector compatibility – Although Medtronic lead connectors conform to International Connector Standards, this lead has not been tested for use with non-Medtronic devices. The known potential adverse consequences of using such a combination may include undersensing of cardiac activity, failure to deliver necessary therapy, or an intermittent electrical connection.
Electrophysiologic testing – Electrophysiologic evaluation and testing should be performed at the discretion of the physician taking into consideration the current clinical guidelines.
