ICD 10 DORSAL COLUMN STIMULATOR TRIAL

Successful implantation of a high-frequency SCS device in a patient with a prior ICD has been reported with close cardiac monitoring during the trial period and at time of implantation.

At no point in the trial were any artifact interactions noted between the implanted SCS and an implanted Medtronic cardiac device (implantable pulse generator or ICD), indicating that patients can safely have dual Medtronic devices implanted and operational. No statistically significant differences were observed between the control and treatment arms in ventricular tachycardia/ventricular fibrillation episodes or rate of nonsustained ventricular tachycardia and premature ventricular complexes among 19 control and 33 treated patients that had concomitant ICDs and had reported device data available for analysis. Seventy-six percent (50 of 66) had an ICD at the baseline visit.

The results of this trial suggest that high thoracic SCS is safe and feasible in patients with an implanted defibrillator.Īnother study looked at a potential change in left ventricular end-systolic volume index from baseline to six months of SCS therapy in the treatment arm compared with the control arm, as measured by echocardiography.

The leads were placed at T1–3 with a frequency of 50 Hz and 200-ms pulse width, which are similar to the parameters used in chronic pain conditions. No deaths or device-device interactions were noted during the six-month period in the 17 SCS-treated patients. There were no reported instances of SCS directly impacting ICD/PPM function, including detection of arrhythmias and delivering therapies.Ī recent prospective, multicenter pilot trial was performed to evaluate the safety and effectiveness of an SCS system for the treatment of systolic heart failure. In-depth testing was performed intraoperatively including arrhythmia induction attempts to test detection and termination by the ICD under the supervision of cardiac electrophysiology specialists. Lead polarity of the cardiac devices was not specified. A recent prospective double-blind randomized controlled trial (RCT) pilot study demonstrated no interference between patients with an ICD followed by SCS implantation for the treatment of systolic heart failure in nine patients. Engaard reported successful placement in five cases without specification of bipolar or unipolar leads of the ICD. There have been multiple reports of uncomplicated placement of spinal cord stimulators in patients with prior PPM/ICD with bipolar leads without interaction when properly monitored during placement. In contrast, a bipolar pacing lead has both the cathode and anode along the same lead, which results in a much shorter path for the current to travel.Īlternatively, mounting evidence has demonstrated safe simultaneous use of SCS and PPM/ICD technologies. These systems are more commonly used in temporary pacing situations where nodal function is expected to return. A unipolar pacing lead only has one electrode in the heart chamber, and the current flows through the heart and back to the pulse generator through the body and soft tissues. Inhibition of PPM function by SCS has been reported in patients for whom the PPM is set in a unipolar mode. Concern about interference between cardiac devices and SCS is based on reports of pacemaker inhibition noted in prior studies. Both of these devices rely on the detection of electrical cardiac activity, rhythm, and rate to function properly. An ICD also senses the rhythm and rate of the heart, but instead of pacing the rate, it delivers a shock to restore a normal heart rhythm. A pacemaker is able to deliver an electrical current to signal cardiac muscle contraction. The primary functions of a pacemaker are to sense the heart rhythm and rate and to pace the heart. In the past, concern has been expressed regarding potential interference of SCS with these potentially life-preserving technologies.Ī basic understanding of PPM and ICD function is paramount in order to grasp the safety considerations of SCS use in patients with these devices. Candidates for SCS may have concomitant arrhythmias, coronary artery disease, heart failure, or other conditions that necessitate permanent pacemaker (PPM) or implantable cardioverter defibrillator (ICD) placement. Off-label uses include peripheral artery disease and refractory angina.

Spinal cord stimulation (SCS), a treatment growing in popularity, is Food and Drug Administration–approved for use in “failed back surgery syndrome” (FBSS), painful peripheral neuropathy, multiple sclerosis, and complex regional pain syndrome, among other disorders.

Myth: Spinal cord stimulation is an absolute contraindication in patients with a prior permanent pacemaker or implantable cardioverter defibrillator.įact: Spinal cord stimulation can be safely performed in these patients through close collaboration among all parties.
