Why the study?
Variable coronary sinus anatomy and procedure complexity during CRT can lead to lead implantation failure or require surgical coronary sinus lead placement.
Does implantation of a coronary sinus lead without a delivery system using a diagnostic catheter and stiff wire allow successful LV lead placement in patients undergoing CRT?
Does implantation of a coronary sinus lead without a delivery system using a diagnostic catheter and stiff wire allow successful LV lead placement in patients undergoing CRT?
Implantation of a coronary sinus lead without a delivery system using a diagnostic catheter and stiff wire is a feasible alternative technique for difficult LV lead placements in CRT.
Small case series supports surgical CRT lead placement in complex anatomy; leaves open need for prospective validation.
