Successful use of venovenous snare to fix the wire in a collateral vein for proper placement of the left ventricular lead during cardiac resynchronization therapy: a case report.

We have used the snare technique, with the use of a snare prepared from a coronary guidewire. Use of such an indigenous snare has not been described before in the literature. The hardware used in this case is routinely used for coronary angioplasty procedures in all catheterization labs. The importance of our case is that no special hardware like dedicated snare was required to negotiate the LV lead at its desired location.
