In‑hospital outcomes of rotational versus orbital atherectomy during percutaneous coronary intervention: a meta‑analysis

Orbital atherectomy for treatment of calcified coronary artery lesions. First experiences in Poland: Short-term outcomes of the Lower-Silesia Orbital Atherectomy Registry (LOAR)

“…The elliptical orbital movement allows for continuous flow of saline and blood during treatment and produces small particle sizes during pulverization. This specific mechanism of action might result in greater plaque modification with a coincidental decrease in the periprocedural slow/no-flow phenomenon rate, yet it might also increase the dissection rate [3,8,9]. The results of our study partially support earlier findings.…”

First experience with orbital atherectomy in calcified unprotected left main percutaneous coronary intervention

“…Our case series, among the first in the literature [ 4 , 5 ] showed that the OA system can be a safe and effective debulking device in cases of high-risk LM lesions. Therefore, considering that subjects with calcified LM lesions are often under-represented in randomized clinical trials [ 10 – 12 ] and portend higher prognostic risk, there is a strong need for large, multicenter, randomized studies comparing the safety and efficiency of OA to other advanced lesion preparation methods (RA and S-IVL) in terms of LM diseases. Additionally, an initial preprocedural and intraprocedural accurate calcification assessment in intravascular imaging is necessary for adequate evaluation of orbital atherectomy efficiency in terms of LM disease.…”

Intravascular Lithotripsy as a Novel Treatment Method for Calcified Unprotected Left Main Diseases—Comparison to Rotational Atherectomy—Short-Term Outcomes

“…Presumably, the data obtained from intravascular imaging, including the IVUS and/or OCT analyses, would provide valuable and precise information regarding the nature of the calcium burden and evidence of calcium modification, along with a comparison of the acute luminal gain achieved by RA compared with S-IVL. The relationship between this data and different mechanisms of plaque modification using both devices [ 47 , 48 , 49 ] could result in the evaluation of new criteria for optimal subjects who qualify for the primary Left Main Rotablation or/and S-IVL; therefore, we strongly believe that future studies which foreground this issue are of urgent clinical need.…”
