Physiological evaluation of the provisional side-branch intervention strategy for bifurcation lesions using instantaneous wave-free ratio.

ABSTRACT:

Background

The provisional side-branch intervention strategy remains the gold standard approach for repair of coronary bifurcation lesions. We performed this study to evaluate the clinical and functional outcomes of using the instantaneous wave-free ratio (iFR) for physiological assessment in provisional side-branch repair of bifurcation lesions.

Methods

Fifty patients with coronary bifurcation lesions were equally divided into two groups: (I) an iFR-guided side-branch intervention group and (II) a conventional group, in which the operator selected a different interventional method. After the procedure, we performed a six-month follow-up for postoperative ejection fraction (EF) and clinical cardiac outcomes.

Results

Our results showed that the iFR measurement procedur
