Predictors of failure in the reverse wire technique for complex coronary bifurcation lesions.

ABSTRACT:

Background

The reverse wire technique (RWT), with a guidewire shaped in a swan-neck configuration, is used to address challenging side branch (SB) wiring in complex coronary bifurcation lesions (CBLs). However, its success is not guaranteed.

Aims

This study aimed to identify factors associated with RWT failure and to assess the feasibility of the balloon blocking technique (BBT) in the distal main vessel (MV) as an alternative.

Methods

Thirty-two consecutive complex CBLs with difficult SB wiring were retrospectively analysed. Patients were divided into two groups: those with successful RWT (RWT-S, n=17) and those who underwent BBT, either after RWT failure or as a primary approach (RWT-F/BBT, n=15). Risk factors for RWT failure were examined.

Results

The succes
