Brief Summary
It is hypothesized that it is both safe and feasible to use an interventional approach to LV lead placement (placing the LV lead guided by acute hemodynamic measurements), and that the LV lead can be placed in a position that is superior to the initial empiric lateral wall LV lead location in less than 30 minutes without significant risk to patients. The time from RV capture to LV activation correlates with the optimal pacing site based on stroke volume \& dP/dt measurements.

Intervention
EXPERIMENTALTen patients undergoing LV lead placement for either initial CRT device implant or revision of an existing system at Lancaster General Hospital who meet the inclusion and exclusion criteria will be screened and approached for enrollment in this safety and feasibility study. Study participants may have ischemic or non-ischemic cardiomyopathy; results for ischemic and non-ischemic patients will be analyzed separately. Any device system from any manufacturer may be used; the choice of device and leads will be at the implanting physician's discretion. Post implant procedures will be the same as those for any CRT implant. Outpatient follow-up other than the 1-month follow-up will be per the implanting physician's usual practice.
Interventions
The physician will obtain right femoral arterial access and advance the pressure/conductance catheter to the LV utilizing the retrograde approach. Baseline dP/dt and stroke volume will be recorded in the patient's presenting rhythm. The dP/dt and stroke volume will be measured during biventricular pacing. Hemodynamic measurements will be made with the tip of the pacing lead in the distal vessel, followed by repeat measurements with the lead positioned in the mid and proximal portions of the initially selected vein. The pacing and hemodynamic measurements will be repeated with the CS lead positioned in two additional veins (if possible). The pressure/conductance catheter will be removed from the left ventricle after 30 minutes, regardless of the number of pacing sites identified/tested. The physician will make the choice of the LV lead placement based on the information gathered up to that point.
Eligibility Criteria
You may qualify if:
- Ischemic or non-ischemic cardiomyopathy
- Patient meets all current criteria for CRT (NYHA Class III-IV heart failure, QRS ≥ 120 ms, LVEF ≤ 35%, optimal medical therapy).
- Patient willing/able to sign study informed consent and HIPAA authorization.
You may not qualify if:
- Patient does not meet current criteria for CRT implant
- Mechanical aortic valve
- Left ventricular thrombus
- Aortic stenosis
- No palpable femoral pulse
- Extensive atherosclerotic disease of the aorta
- Serum creatinine \> 2.5
- Patient not willing/able to sign study informed consent/HIPAA authorization.
