Aims:
Ideal positioning of left ventricular (LV) pacing lead in cardiac resynchronization therapy (CRT) is technically demanding. This case aims to place LV lead in anterolateral branch of coronary sinus (CS) using collateral route blindly.
Methods And Results:
Externalization via the CS ostium using collaterals retrogrogradely, which was not visible in initial balloon occlusion venography, through one delivery sheath with the support of commonly used micro-guide catheter and subsequent successful LV lead placement in anterolateral branch of CS.
Conclusion:
This innovative retrograde approach for LV pacing lead implantation in anterolateral branch of CS obviated the need for snare technique to capture the distal end of the wire when antegrade route was not successful.
