The Effect of an Azygos Vein Coil on Defibrillation Threshold

Washington University School of Medicine·interventional·Posted Nov 26, 2008·Updated Sep 28, 2018

In Brief

A clinical study evaluating Standard configuration vs. azygos coil for Heart Failure. Completed, enrolled 32 participants across 1 site.

Detailed Summary

When implantable cardiac defibrillators are implanted (ICDs), the defibrillation threshold (DFT), of the amount of energy required to effectively terminate life-threatening arrhythmias is determined. The device is then programmed to discharge a larger amount of energy in order to provide a safety margin. In some patients, the DFT is so high, that an adequate safety margin is not programmable. Placement of a defibrillation lead in the azygos vein has been found to be helpful in these patients. This goal of this trial is to attempt to quantify the average reduction in the DFT (if any) that results from the addition of the azygos lead.
