Early instability requires close initial monitoring after coronary sinus lead placement; leaves open need for dedicated lead designs in severe heart failure.
What are the adverse events associated with the implantation of a transvenous left ventricular pacing system in patients with severe heart failure and left bundle branch block?
Transvenous left ventricular pacing via the coronary sinus is feasible in severe heart failure, though early lead dislodgement and threshold increases are frequent, highlighting the need for specialized leads.
