Does coronary stent placement stabilize a dislodged left ventricular lead during CRT-D implantation?
Coronary stent placement can be a useful and safe technique to stabilize a left ventricular lead in patients with complicated coronary sinus anatomy or lead instability.
May offer bailout stabilization for unstable LV leads in CRT; hypothesis-generating case report requiring prospective validation.
During cardiac resynchronization therapy implantation, left ventricular lead placement involves transvenous placement of leads via the coronary sinus and into a tributary branch. At present, the most widely used method for left ventricular (LV) lead placement involves a transvenous LV lead placement via the coronary sinus into a tributary branch. Lead dislodgement is a common cause for reoperation. We describe a case where a coronary stent was placed to stabilize the lead against the vessel wall.

Agarwal et al. (2018) conducted a case report in Left ventricular lead dislodgement (n=1). Coronary stent placement for LV lead stabilization was evaluated on Left ventricular lead stability. Coronary stent placement successfully stabilized a left ventricular lead in a patient with target vein-lead diameter mismatch, maintaining satisfactory parameters at one-month follow-up.
