ABSTRACT
Objective: There is limited evidence on feasibility and safety of only heparin rota-flush(OHRF)solution in rotational atherectomy (RA). We compared the safety and efficacy of OHRF solution with alternative rotaflush (ARF) solution in patients who underwent RA. Methods: A total of 48 patients who underwent RA were enrolled in the study. In 25 patients OHRF solution and in 23 patients ARF solution was utilized. The study end points were procedural success rateandrota-related adverse cardiovascular event (RRAE) including slow flow, no reflow, bradycardia, and hemodynamic instability. Results: Procedural success was achieved in all patients in both the OHRF and ARF groups. There was no statistically significant difference in RRAE between the two groups(32.0% vs. 34.7%, p ¼ 0.83). Conclusion: OHRF solution appears a more simplistic solution while performing rotablation as compared to ARF solution. Side effects such as hypotension and bradycardia can be circumvented with OHRF solution during rotablation
