The purpose of this research study is to test the function of a subjects implantable cardioverter defibrillator (ICD) function throughout the duration of their heart surgery. ICD function can be altered during some types of heart surgery such as those when a pump (ventricular assist device - VAD) is implanted. The investigators would like to study the mechanism of device and ICD malfunction.
ICD function is typically measured prior to and after surgery. For the study, the investigators will measure ICD lead function multiple times throughout the surgery as well, to determine if and when device malfunction occurs. ICD lead function is measured noninvasively through a specialized computer the same way it is checked in the clinic. In addition, the investigators will test ICD function as they usually do following surgery.

observational study to assess potential changes that may occur in the RV ICD lead function during LVAD implantation and what mechanism may cause those changes in RV ICD lead function
Time frame: RV ICD lead function will be measured throughout LVAD placement , at 1 week post LVAD placement, and 3 months post LVAD placement Description:
