Background: With advancements in stent designs and lesion preparation techniques, complex lesions are being increasingly treated using percutaneous approach1. Even with advent of new emerging technologies, the importance of RA cannot be undermined as a first line technique for treating complex calcified lesions1-3.

Objectives: We looked at several aspects including technique, success rate and safety of Rotawireas a standalone wire for Rotational Atherectomy (RA).

Material and Methods: Patients undergoing RA were prospectively assigned to stand alone Rotawire strategy (strategy-A) vs the contemporary technique using workhorse wire and exchanges over a microcatheter (strategy-B). Success rate, wiring fluoro times and complication rate of both strategies were compared.

Results: Twenty-six patients underwent RA from January 2018 to 2020. Strategy-A was selected for 12 and strategy-B for 14 patients, as per operators’ discretion. Baseline and procedural characteristics were similar in both groups. Strategy-A was successful in 11 (91.67%) and strategy-B in 14 (100%) of patients (P=0.29). The wire handling fluoro time was significantly lower for strategy-A vs B(36.83 ± 4.80 vs 96.36 ± 24.51 seconds, P value 0.01), however the total procedural fluoro time was not statistically different (17.75 ± 4.78 vs 19.57 ± 3.58 minutes, P value 0.29). Slow flow was the only complication (A=8.3% vs B=7.1%, P value 0.91), treated successfully with final TIMI-III flow in all patients. The microcatheter usage (8.3% vs 100%, P=0.01) and number of PTCA wires usage (1.08 ± 0.29 vs 2.0± 0,P=0.01), was significantly lower for strategy-A. There was no MACCE at 01 month.

Conclusion: By using proper technique, the Rotawire can be used as a standalone wire for RA assisted interventions. Larger studies can validate it further.
