Key result
Novel active-fixation LV lead achieves successful implantation in a very-large-diameter coronary vein.
Why the study?
Placement of a left ventricular lead in an adequate location for CRT can be complex due to challenging coronary vein anatomies, including very-large-diameter veins.
Case Report (n=1)
A novel left ventricular active fixation lead can be successfully implanted in patients with challenging coronary vein anatomies, such as a very-large-diameter coronary vein.
May enable LV pacing in oversized veins; hypothesis-generating, requiring prospective validation before practice change.
Cardiac resynchronization therapy (CRT) has proved to be beneficial for patients with moderate-to-severe heart failure with prolonged QRS duration and reduced left ventricular ejection fraction. Placement of a left ventricular (LV) lead in an adequate location has been shown to increase response to CRT1,2 but can become a complex procedure because of challenging coronary vein anatomies. We report the case of a patient in whom a novel LV lead was successfully implanted in a very-large-diameter coronary vein.

Giannola et al. (2015) conducted a case report in Heart failure with challenging coronary vein anatomy (n=1). Novel left ventricular active fixation lead was evaluated on Successful implantation. A novel left ventricular active fixation lead was successfully implanted in a very-large-diameter coronary vein in a patient with challenging anatomy.
