Title : Rotational atherectomy for the management of bifurcation lesions: a pilot randomized study

Abstract

BACKGROUND: Coronary bifurcation lesions are often seen in interventional practice and result in challenges in management. In spite of defined techniques side branch compromise is still the most important problem. Currently standard strategy recommended is a 1-stent technique: plain old balloon angioplasty (POBA) and provisional stenting. Published non-randomized data showed in up to 26% the indication for RA was to preserve side branch. Randomized comparison of rotational atherectomy and provisional stenting (RAPS) with standard strategy (SS) for the treatment of bifurcation lesion (BL) is needed.

METHODS: We conducted a single center prospective randomized pilot study of consecutive patients from our Institution. Consecutive patients with BL have been screened. We compared RAPS vs SS. Lesions must be located only in the main vessel (BLMV). Primary endpoint was need for side-branch treatment.

RESULTS: 148 pt were included: 74 patients (95 RA) were enrolled in the RAPS group and 74 patients were included in the SS group. BL most treated was proximal LAD. Primary endpoint was lower in RA+: 1.1% vs 31.2% (p < 0.001) in RAPS vs SS. TVF were 13.1% and 24.8% (p = 0.04) in RAPS and SS respectively. Primary endpoint and TVF were higher if BL<70º in comparison with BL ?70º (p= 0.03 and p = 0.02) in both groups.

CONCLUSIONS: Need for SB treatment and TVF were lower in RAPS approach than in SS. BL<70º increases SB compromise and TVF rates. SS was associated with a 4.92 times greater risk of SB compromise than RAPS in BL <70º. This data reinforce the perception of an overall clinical relevance RAPS approach for SB patency.
