Abstract
BackgroundSeverely calcified coronary lesions with reduced left ventricular (LV) function result in worse outcomes. Atherectomy is used in treating such lesions when technically feasible. However, there is limited data examining the safety and efficacy of atherectomy without hemodynamic support in treating severely calcified coronary lesions in patients with reduced left ventricular ejection fraction (LVEF).ObjectiveTo evaluate the clinical outcomes of atherectomy in patient with reduced LVEF.MethodsWe searched PubMed, Cochrane CENTRAL Register and ClinicalTrials.gov (inception through July 21, 2021) for studies evaluating the outcomes of atherectomy in patients with severe LV dysfunction. We used random-effect model to calculate risk ratio (RR) with 95% confidence interval (CI). The endpoints were in-hospital and long term all-cause mortality, cardiac death, myocardial infarction (MI), and target vessel revascularization (TVR).ResultsA total of 7 studies consisting of 2,238 unique patients were included in the analysis. The median follow-up duration was 22.4 months. The risk of in-hospital all-cause mortality using atherectomy in patients with severely reduced LVEF compared to the patients with moderate reduced or preserved LVEF was [2.4vs.0.5%; RR:5.28; 95%CI 1.65–16.84; P = 0.005], the risk of long term all-cause mortality was [21 vs. 8.8%; RR of 2.84; 95% CI 1.16–6.95; P = 0.02]. In-hospital TVR risk was 2.0 vs. 0.6% (RR: 4.15; 95% CI 4.15–15.67; P = 0.04) and long-term TVR was [6.0 vs. 9.9%; RR of 0.75; 95% CI 0.39–1.42; P = 0.37]. In-hospital MI was [7.1 vs. 5.4%; RR 1.63; 95% CI 0.91–2.93; P = 0.10], long-term MI was [7.5 vs. 5.7; RR 1.74; 95%CI 0.95–3.18; P = 0.07).ConclusionOur meta-analysis suggested that the patients with severely reduced LVEF when using atherectomy devices experienced higher risk of clinical outcomes in the terms of all-cause mortality and cardiac mortality. As we know that the patients with severely reduced LVEF are inherently at increased risk of adverse clinical outcomes, this information should be considered hypothesis generating and utilized while discussing the risks and benefits of atherectomy in such high risk patients. Future studies should focus on the comparison of outcomes of different atherectomy devices in such patients. Adjusting for the inherent mortality risk posed by left ventricular dysfunction may be a strategy while designing a study.

Is crossability of the classic crown with the glide assist superior to the micro crown in the Diamondback 360® coronary orbital atherectomy system? Cardiovasc Interv Ther 2020; 35:361-370. [PMID: 31939066 DOI: 10.1007/s12928-020-00640-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2019] [Accepted: 12/31/2019] [Indexed: 10/25/2022]
Abstract
The Diamondback 360® coronary orbital atherectomy system (OAS) can safely debulk calcified lesions by pullback of the crown, if the crown is advanced to the distal of the lesion. The aim of this study was to compare crossability with two types of crown in OAS. Thirty-six consecutive severely calcified lesions in 33 patients who underwent percutaneous coronary intervention with the coronary OAS were included. The micro crown was used in 18 consecutive lesions from April 2018 to February 2019, and the classic crown with the glide assist was used in 18 consecutive lesions from March 2019 to August 2019. Good crossability was defined as the ability to cross the lesion before orbital atherectomy or to cross the lesion with a first session of orbital atherectomy. We also tried to elucidate whether the crown could cross the lesion without using the glide assist in 13 consecutive lesions at the end of the classic crown cases. Good crossability was more often observed in cases with the classic crown (17 of 18 lesions, 94%) than the micro crown (6 of 18 lesions, 33%) (P < 0.001). In 13 consecutive lesions at the end of the classic crown cases, the crown could cross the lesion in 4 lesions (31%) without use of the glide assist or orbital atherectomy, and in 11 lesions (85%) with only use of the glide assist (P = 0.005). The classic crown with the glide assist is superior to the micro crown in terms of crossability for severely calcified lesions.

Abstract
Successful percutaneous coronary intervention (PCI) can be challenging in the presence of heavily calcified lesions. Severely calcified lesions are associated with worse clinical outcomes. Recognition of calcification is important before stenting to ensure adequate stent expansion can be attained. Orbital atherectomy is a safe and effective method to ablate calcified plaque. Lesion preparation through plaque modification with orbital atherectomy before stent implantation can help to optimize the results of PCI in these complex lesions.
