ARROYO, Alonso et al. Implant of a left ventricular pacing electrode by double cannulation of the coronary sinus, snare technique and retrograde access of the posterolateral vein. Rev. Colomb. Cardiol. [online]. 2022, vol.29, n.2, pp.240-243.  Epub 19-Maio-2022. ISSN 0120-5633.  https://doi.org/10.24875/rccar.m22000132.

The percutaneous implantation of a left ventricular pacing electrode through the coronary sinus for cardiac resynchronization has always been a challenge, especially in patients with a complex coronary venous anatomy. This case shows how double cannulation of the coronary sinus using a multisnare catheter allows a left ventricular pacing electrode to be placed through retrograde access to a stenotic posterolateral vein, with a good clinical outcome.
