Meta-Analysis Review
Safety and feasibility of rotational atherectomy (RA) versus conventional stenting in patients with chronic total occlusion (CTO) lesions: a systematic review and meta-analysis.
BACKGROUND AND AIM
Interventional cardiologists face challenges in managing chronic total occlusion (CTO) lesions, with conflicting results when comparing rotational atherectomy (RA) to conventional PCI. This meta-analysis aims to provide a critical evaluation of the safety and feasibility of RA in CTO lesions.
METHODS
PubMed, Scopus, Web of Science, Ovid, and Cochrane central library until April 2023 were searched for relevant studies. MACE was our primary outcomes, other outcomes were all cause of death, cardiac death, MI, and TVR. Also, we reported angiographic outcomes as technical success, procedural success, and procedural complications in a random effect model. The pooled data was analyzed using odds ratio (OR) with its 95% CI using STATA 17 MP.
RESULTS
Seven studies comprising 5494 patients with a mean follow-up of 43.1 months were included in this meta-analysis. Our pooled analysis showed that RA was comparable to PCI to decrease the incidence of MACE (OR = 0.98, 95% CI [0.74 to 1.3], p = 0.9). Moreover, there was no significant difference between RA and conventional PCI in terms of other clinical or angiographic outcomes.
CONCLUSION
Our study showed that RA had comparable clinical and angiographic outcomes as conventional PCI in CTO lesions, which offer interventional cardiologists an expanded perspective when addressing calcified lesions.

We aimed to describe the clinical characteristics and outcomes of patients who underwent atherectomy at the time of percutaneous coronary intervention in centers with on-site surgical centers (SCs) versus nonsurgical centers (NSCs). Patients treated with coronary atherectomy between January 1, 2006, to December 31, 2019, from the British Cardiovascular Society Intervention (BCIS) registry were included. Primary outcomes were in-hospital all-cause mortality and major adverse cardiovascular and cerebrovascular events. A total of 20,833 patients were treated with coronary atherectomy, of which 7,983 (38%) were performed at NSC. The proportion of coronary atherectomies performed in NSC increased from 12.5% in 2006 to 42% in 2019. Compared with patients treated at SC, patients treated in NSC were older (mean age 75.1 ± SD years vs 74.2 ± SD, p <0.001), but had comparable prevalence of hypertension (NSC 73.9% vs SC 72.8%, p = 0.085), diabetes mellitus (NSC 32.2% vs SC 31.6%, p = 0.43) and renal disease (NSC 6.0% vs SC 6.0%, p = 0.99). Intracoronary imaging was used more often in NSC than SC (22.3% vs 19.4%, p <0.001). After adjustment, the odds of in-hospital mortality (odds ratios [OR] 0.76, 95% confidence intervals [CI] 0.50 to 1.16), major adverse cardiovascular and cerebrovascular events (OR 0.80, 95% CI 0.53 to 1.21), emergency coronary artery bypass graft (OR 0.49, 95% CI 0.15 to 1.57), major bleeding (OR 0.67, 95% CI 0.36 to 1.24) and coronary perforation (OR 1.07, 95% CI 0.97 to 1.43) in NSC were comparable with SC. In conclusion, coronary atherectomy in hospitals with off-site surgical cover has become more frequent, with no association with poorer outcomes, compared with hospitals with on-site surgical cover.

Combined therapy with rotational atherectomy and drug coated balloon for superficial femoral artery in-stent restenosis: safety, efficacy, and two-year results of a single center experience.
BACKGROUND
The primary patency rate of superficial femoral artery (SFA) after percutaneous transluminal angioplasty (PTA) has improved with the use of self-expanding stents. However, occurrence of in-stent restenosis (ISR) still represents a frequent problem. Despite different studies have assessed the role of atherectomy and drug coated balloons (DCBs), no long-term data exist about combined use. The aim of this study was to evaluate safety and efficacy of combined treatment with Jetstream (Boston Scientific Corp., Marlborough, MA, USA) atherectomy and DCB for SFA intrastent restenosis (ISR) at 2-year follow-up.
METHODS
30 patients treated with PTA from November 2018 to September 2019 at Montevergine Clinic (Mercogliano, Avellino, Italy) were included in this analysis. All patients underwent PTA of SFA-ISR with Jetstream Atherectomy System followed by paclitaxel eluting balloon treatment. Patients were evaluated at 30 days, and every 3 months up to 24.
RESULTS
Technical and procedural success was achieved in every patient. No in-hospital major adverse cardiac and cerebrovascular events occurred. No acute and sub-acute(in-hospital) procedure related complications occurred. During follow-up, 1 patient died due to stroke. Primary patency rate at 12 months was 93.4%. Primary patency rate at 24 months was 83.4%. Secondary patency rate at 24 months was 96.7%. One minor amputation, planned before treatment, was performed in the first 30 days.
CONCLUSIONS
Our data suggest that combined therapy with Rotational Atherectomy and DCBs for SFA-ISR represents a safe and effective procedure with a high rate of primary patency at 2-year follow-up.

Meta-Analysis Review
PURPOSE
Infrapopliteal lesions are generally complex to treat due to small vessel diameter, long lesion length, multilevel disease, and severe calcification. Therefore, different vessel preparation devices have been developed to contribute to better peri- and postprocedural outcomes. This systematic review aims to compare different vessel preparation techniques prior to plain old balloon angioplasty (POBA) or drug-coated balloon (DCB) angioplasty with POBA or DCB alone in infrapopliteal arterial disease.
METHODS
Medline, EMBASE, and Cochrane databases were searched for studies published between 2000 and 2022 assessing the value of adjunctive vessel preparation in infrapopliteal arterial disease. The primary outcomes were 12-month primary patency and limb salvage.
RESULTS
A total of 1685 patients with 1913 lesions were included in 11 POBA studies. Methodological quality was assessed as poor to moderate in these studies. Only 2 studies with 144 patients assessed vessel preparation in conjunction with DCB angioplasty. These randomized trials were assessed as high quality and found no significant benefit of adjunctive atherectomy to DCB angioplasty. The pooled Kaplan-Meier estimates of 12-month primary patency and limb salvage in the POBA studies were 67.8% and 80.9% for POBA, 62.1% and 86.4% for scoring balloons, 67.9% and 79.6% for mechanical atherectomy (MA), and 79.7% and 82.6% for laser atherectomy, respectively. Within the pooled data only scoring balloons and MA demonstrated significantly improved 12-month limb salvage compared to POBA.
CONCLUSIONS
Different forms of adjunctive vessel preparation demonstrate similar 12-month outcomes compared to POBA and DCB angioplasty alone in infrapopliteal disease, with the exception of improved 12-month limb salvage in scoring balloons and MA. However, since the included studies were heterogeneous and assessed as poor to moderate methodological quality, selection bias may have played an important role. Main conclusion is that this systematic review found no additional value of standard use of vessel preparation.
CLINICAL IMPACT
Infrapopliteal arterial disease is associated with chronic limb-threatening ischemia (CLTI) and generally complex to treat due to small vessel diameter, long lesion length, multilevel disease and severe calcification. A wide range of vessel preparation devices have been developed to contribute to improved peri- and postprocedural outcomes in these complex lesions. This systematic review aims to compare different vessel preparation techniques prior to plain old balloon angioplasty (POBA) or drug coated balloon (DCB) angioplasty with POBA or DCB angioplasty alone in infrapopliteal arterial disease. Different forms of adjunctive vessel preparation demonstrate similar 12-month outcomes compared to POBA and DCB angioplasty alone in infrapopliteal disease, with the exception of improved 12-month limb salvage in scoring balloons and mechanical atherectomy (MA). However, since the included studies were heterogeneous and assessed as poor to moderate methodological quality, selection bias may have played an important role. Main conclusion is that this systematic review found no additional value of standard use of vessel preparation.

BACKGROUND
Rotational atherectomy (RA) during percutaneous coronary intervention may cause transient bradycardia or a higher-degree heart block. Traditionally, some operators use prophylactic transvenous pacing wire (TPW) to avoid haemodynamic complications associated with bradycardia.
OBJECTIVE
We sought to establish the frequency of bail-out need for emergency TPW insertion in patients undergoing RA that have received no upfront TPW insertion.
METHODS
We performed a single-centre retrospective study of all patients undergoing RA between October 2009 and October 2022. Patient characteristics, procedural variables, and in-hospital complications were registered.
RESULTS
A total of 331 patients who underwent RA procedure were analysed. No patients underwent prophylactic TPW insertion. The mean age was 73.3 ± 9.1 years, 71.6% ( = 237) were male, while nearly half of the patients were diabetic [ = 158 (47.7%)]. The right coronary artery was the most common target for RA (40.8%), followed by the left anterior descending (34.1%), left circumflex (14.8%), and left main stem artery (10.3%). Altogether 20 (6%) patients required intraprocedural atropine therapy. Emergency TPW insertion was needed in one (0.3%) patient only. Eight (2.4%) patients died, although only one (0.3%) was adjudicated as being possibly related to RA-induced bradycardia. Five patients (1.5%) had ventricular fibrillation arrest, while nine (2.7%) required cardiopulmonary resuscitation. Six (1.8%) procedures were complicated by coronary perforation, two (0.6%) were complicated by tamponade, while 17 (5.1%) patients experienced vascular access complications.
CONCLUSIONS
Bail-out transvenous temporary pacing is very rarely required during RA. A standby temporary pacing strategy seems reasonable and may avoid unnecessary TPW complications compared with routine use.

Although rotational atherectomy (RA) and intravascular lithotripsy (IVL) have been proved to be effective for calcified de novo coronary lesions, their use in patients with in-stent restenosis (ISR) is still controversial. No comparison of these techniques in patients with ISR has been published so far. We sought to evaluate safety and feasibility of RA and IVL in patients with calcified ISR. Furthermore, we aimed to compare in-hospital and 1-year clinical outcomes between both groups. This is a retrospective single-center study evaluating patients with calcified ISR treated with RA (between 2012 and 2021) and IVL (between 2019 and 2021). Inhospital and 1-year clinical outcomes were compared between IVL and RA patients. In total, 28 patients with ISR who underwent RA were compared with 24 ISR subjects after IVL. The procedural success rate was 100% in both the groups. Quantitative coronary analysis demonstrated a similar degree of stenosis prior (66.4 ± 11.4 vs 68.8 ± 19.7, p = nonsignificant [NS]), and after the procedure (21.5 ± 20.5 vs 22.8 ± 12.1, p = NS) with no difference in acute luminal gain (1.34 ± 0.60 vs 1.38 ± 0.59, p = NS). There was one in-hospital major adverse cardiovascular event in the RA group. At 1-year follow-up, no difference was observed with respect to major adverse cardiovascular event rate (14.3% vs 16.7%, p = NS) and target vessel revascularization (7.1% vs 12.5%, p = NS). In conclusion, RA and IVL are safe and feasible techniques for calcified ISR yielding comparable results at 1-year follow-up. Further clinical studies are warranted to confirm our findings and shed more light on patient and lesion characteristics associated with the best outcomes.

EuroIntervention : Journal of EuroPCR... Jan 2024Percutaneous coronary intervention (PCI) of calcified lesions remains challenging for interventionalists. (Randomized Controlled Trial)
Randomized Controlled Trial
BACKGROUND
Percutaneous coronary intervention (PCI) of calcified lesions remains challenging for interventionalists.
AIMS
We aimed to investigate whether combining rotational atherectomy (RA) with cutting balloon angioplasty (RA+CBA) results in more optimal stent expansion compared with RA followed by non-compliant balloon angioplasty (RA+NCBA).
METHODS
ROTA-CUT is a prospective, multicentre, randomised trial of 60 patients with coronary artery disease undergoing PCI of moderately or severely calcified lesions with drug-eluting stent implantation. Patients were randomised 1:1 to either RA+CBA or RA+NCBA. The primary endpoint was the minimum stent area on intravascular ultrasound (IVUS). Secondary endpoints included minimum lumen area and stent expansion assessed by IVUS and acute lumen gain, final residual diameter stenosis and minimum lumen diameter assessed by angiography. Clinical endpoints were obtained at 30 days.
RESULTS
The mean age was 71.1±9.4 years, and 22% were women. The procedural details of RA were similar between groups, as were procedure duration and contrast use. Minimum stent area was similar with RA+CBA versus RA+NCBA (6.7±1.7 mm vs 6.9±1.8 mm; p=0.685). Furthermore, there were no significant differences regarding the other IVUS and angiographic endpoints. Procedural complications were rare, and 30-day clinical events included 2 myocardial infarctions and 1 target vessel revascularisation in the RA+CBA group and 1 myocardial infarction in the RA+NCBA group.
CONCLUSIONS
Combining RA with CBA resulted in a similar minimum stent area compared with RA followed by NCBA in patients undergoing PCI of moderately or severely calcified lesions. RA followed by CBA was safe with rare procedural complications and few clinical adverse events at 30 days.

Randomized Controlled Trial
BACKGROUND
Rotational atherectomy (RA) may cause bradyarrhythmias and transitory atrioventricular block when performed in the right coronary artery (RCA) or a dominant circumflex (CX) coronary artery. However, there are no studies of a solution that can prevent coronary flow deterioration and bradycardia complications that may occur during RA. We aimed to create an alternative rota-flush solution to minimize the risk of bradycardia and complete atrioventricular block (AVB) that can occur during RA.
MATERIALS AND METHODS
The study comprised 60 patients who were randomly divided into two groups: 30 received rotaphylline (= 240 mg aminophylline, 10,000 U unfractionated heparin, and 2000 mcg nitroglycerin to 1000 mL saline), and 30 received the traditional rota-flush (= 10,000 U unfractionated heparin, 2000 mcg nitroglycerin, and 1000 mL saline). The incidence of bradycardia or high-grade AVB (HAVB) during RA, coronary slow-flow phenomenon or no-reflow phenomenon, and coronary spasm were the primary endpoints of the study. Procedure success and RA-related procedural complications were secondary endpoints.
RESULTS
The use of rotaphylline was an independent predictor of bradycardia and HAVB after accounting for all other factors (OR: 0.47, 95% CI: 0.24-0.79, p < 0.001). Lesion length (OR: 2.17, 95% CI: 1.24-3.04, p < 0.001), burr-to-artery ratio (OR: 0.59, 95% CI: 0.39-1.68, p < 0.001), and total run duration (OR: 0.79, 95% CI: 0.35-1.43, p < 0.001) were additional independent predictors.
CONCLUSION
Bradycardia and the development of HAVB may be avoided by rotaphylline intracoronary infusion during RA applied to the RCA and dominant CX lesions. Multicenter studies including sizable patient populations should be conducted to validate the present findings.

INTRODUCTION
Coronary artery calcification remains a challenge in percutaneous coronary interventions, due to the higher risk of suboptimal result with subsequent poor clinical outcomes. Intravascular lithotripsy is a novel way of treating severe coronary calcification as it has the ability to modify calcium both circumferentially as well as transmurally, facilitating stent expansion and apposition. We conducted a systematic overview of the published literature on intravascular lithotripsy (IVL) assessing the efficacy and feasibility of IVL in treating severe coronary calcification.
EVIDENCE ACQUISITION
Of the retrieved publications, 62 met our inclusion criteria and were included. A total of 1389 patients (1414 lesions) with significant coronary calcification or under-expanded stents underwent IVL.
EVIDENCE SYNTHESIS
The mean age was 72.03 years (74.7% male). There was a significant improvement in acute and sustained vessel patency, with mean minimal lumen diameter of 2.78±0.46 mm, resulting in acute gain of 1.72±0.51 mm. The acute procedural success rate was 78.2 to 100% with in-hospital complication rate of 5.6 to 7.0%. The majority of the studies reported 30-day MACE, which was between 2.2 to 7.8%.
CONCLUSIONS
The recent studies have highlighted that the use of IVL with adjuvant intracoronary imaging has revolutionized the way of treating heavily calcified, non-dilatable coronary lesions and is likely to succeed the conventional ways of treating these complex lesions. We need further studies to gauge the long-term efficacy and safety of IVL against techniques currently available for calcium modification including conventional balloons, cutting or scoring balloons, rotational atherectomy and laser atherectomy.
