Why the study?
Does the number and diameter of implanted leads increase the risk of venous stenosis in patients undergoing transvenous lead placement?
Does the number and diameter of implanted leads increase the risk of venous stenosis in patients undergoing transvenous lead placement?
The risk of venous stenosis after transvenous lead placement is significantly associated with the number of leads, total lead diameter, and multiple implant procedures.
May warrant caution with multiple leads; leaves open causal prevention via prospective trials.
A significant association exists between venous stenosis and the number of implanted leads and also the sum of the lead diameters. When combined with multiple implant procedures, the incidence of venous stenosis is increased.
