Stimulation of the left ventricle through the coronary sinus with a newly developed ‘over the wire’ lead system — early experiences with lead handling and positioning
Why the study?
Does a newly developed 'over the wire' lead system provide acceptable sensing and pacing thresholds for left ventricular stimulation via the coronary sinus in patients with congestive heart failure?
Population
15 patients with congestive heart failure (6 males, 9 females, mean age 53 +/- 9 years).

Implication
May support early CS lead feasibility in HF; leaves open long-term performance in larger cohorts.

Population
15 patients with congestive heart failure (6 males, 9 females, mean age 53 +/- 9 years).
I
Intervention
Stimulation of the left ventricle using a newly designed guiding catheter and an 'over the wire' pacing lead via the coronary sinus (OTW-CV lead).
O
Outcome
Access time to coronary sinus, R wave amplitudes, pacing impedance, and pacing thresholds at apical, mid-ventricular and basal positions.surrogate
The new 'over the wire' lead system provides uncomplicated access to the coronary sinus with acceptable left ventricular sensing and pacing thresholds for chronic use in cardiac rhythm management.
