Meta-Analysis
BACKGROUND
Rotational and orbital coronary atherectomy (CA) are commonly utilized to treat complex calcified coronary lesions. We conducted a meta-analysis to evaluate sex differences in procedural complications and clinical outcomes after CA.
METHODS
PubMed, Google Scholar, and Cochrane databases were searched for all studies comparing sex differences in procedural and clinical outcomes following CA. The outcomes of interest were procedural complications (coronary dissection, stroke, major bleeding, coronary perforation, cardiac tamponade, and slow or no flow in target vessel) and the clinical outcomes (including early mortality, mid-term all-cause mortality, stroke, myocardial infarction, and target vessel revascularization). Pooled risk ratios (RRs) with their corresponding 95% confidence intervals (CIs) were calculated using the Mantel-Haenszel random-effects model.
RESULTS
Six observational studies with 3517 patients (2420 men and 1035 women) were included in this meta-analysis. While there was no significant difference in the early mortality (RR, 1.14; 95% CI, 0.37-3.53; P = 0.83) between men and women, at a mean follow-up of 2.9 years, all-cause mortality was significantly higher in women (RR, 1.29; 95% CI, 1.11-1.49; P = 0.0009). Women had an increased risk of procedure-related stroke (RR, 3.98; 95% CI, 1.06-14.90; P = 0.04), coronary dissection (RR, 2.10; 95% CI, 1.23-3.58; P = 0.006), and bleeding (RR, 2.26; 95% CI, 1.30-3.93; P = 0.004), whereas the rates of coronary perforation, cardiac tamponade, and the risk of slow or no flow in the revascularized artery were similar in both.
CONCLUSION
In our analysis, women undergoing CA are at increased risk of mid-term mortality and procedure-related complications including stroke, coronary dissection, and major bleeding.

Atherectomy Combined with Balloon Angioplasty versus Balloon Angioplasty Alone for de Novo Femoropopliteal Arterial Diseases: A Systematic Review and Meta-analysis of Randomised Controlled Trials.
OBJECTIVE
The efficacy and cost effectiveness of atherectomy for femoropopliteal (FP) arterial diseases have not been determined yet. A systematic review and meta-analysis were performed to compare the efficacy and safety between atherectomy combined with balloon angioplasty (BA) and BA alone for patients with de novo FP steno-occlusive lesions.
METHODS
The Cochrane Library, Medline, and Embase were used to search for studies evaluating outcomes of atherectomy combined with BA compared with BA alone in FP arterial diseases from inception to July 2020. The methodological quality of the included studies was evaluated with the Cochrane Risk of Bias Tool. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework was used to assess the level of evidence for each outcome. The fixed effects model was chosen to combine the data when I < 50%; otherwise, the random effects model was used. Subgroup and sensitivity analyses were performed to further analyse the results.
RESULTS
Four RCTs were included. The meta-analysis showed that atherectomy combined with BA was associated with improved technical success rate (risk ratio [RR] 0.22, 95% confidence interval [CI] 0.13-0.38, p < .001; I = 0; high quality), reduced bailout stenting (RR 0.15, 95% CI 0.07-0.32, p < .001; I = 16%; high quality), and flow limiting dissection (RR 0.24, 95% CI 0.13-0.47, p < .001; I = 0; high quality). No statistically significant difference was found in target lesion revascularisation (TLR), primary patency, mortality, major adverse event (MAE), or ankle brachial index (ABI) after one year follow up.
CONCLUSION
Compared with BA alone, atherectomy combined with BA may not improve primary patency, TLR, mortality rate, or ABI, but may reduce the need for bailout stenting and the incidence of flow limiting dissection and increase the technical success rate in FP arterial diseases. More studies are warranted to further confirm the conclusion.

Meta-Analysis
OBJECTIVES
To compare the safety and efficiency of atherectomy plus drug-coated balloon with drug-coated balloon only for the treatment of femoropopliteal artery lesions.
METHODS
This systematic review and meta-analysis was performed and reported following the requirement of the PRISMA. EMBASE, MEDLINE, and Cochrane library were queried from January 2000 to June 2020 to identify eligible literature. The modified Downs and Black checklist was used to assess the quality of included studies. Outcome measures included bail-out stenting, distal embolization, perforation, hematoma, primary patency at 12 months, target lesion revascularization at 12 months, leg amputation at 12 months, and mortality at 12 months. We used DerSimonian and Laird random-effects model to pool the dichotomous data on risk ratio (RR) with 95% confidence intervals (CIs) from each study to obtain an overall estimate for major outcomes. Subgroup analysis and sensitivity analyses were conducted.
RESULTS
Six studies (two randomized controlled trials and four retrospective cohort studies) with 470 patients were included. Atherectomy plus drug-coated balloon group was associated with lower rates of bail-out stenting (RR: 0.49, 95%CI: 0.34-0.71, < 0.001). There was no significant difference between two groups in terms of distal embolization (RR: 2.06, 95%CI: 0.51-8.38, = 0.31), perforation (RR: 2.04, 95%CI: 0.43-9.71, = 0.37), hematoma (RR: 1.75, 95%CI: 0.43-7.09, = 0.43), primary patency at 12 months (1.09, 95%CI: 0.98-1.21, = 0.12), target lesion revascularization at 12 months (RR: 0.68, 95%CI: 0.41-1.14, = 0.15), leg amputations at 12 months (RR: 0.54, 95%CI: 0.13-2.23, = 0.39), mortality at 12 months (RR: 2.18, 95%CI: 0.71-6.64, = 0.17). Sensitivity analysis had no effect on our findings.
CONCLUSIONS
The combination of atherectomy and drug-coated balloon was safe and effective in the treatment of femoropopliteal artery lesions, with lower incidence of bail-out stenting compared with drug-coated balloon only.

Short term outcomes of rotational atherectomy versus orbital atherectomy in patients undergoing complex percutaneous coronary intervention: a systematic review and meta-analysis.
Coronary artery calcification (CAC) is one of the paramount hurdles for percutaneous coronary intervention (PCI) since it impedes stent delivery and complete expansion. This study intended to evaluate the short-term clinical and procedural outcomes comparing rotational atherectomy (RA) and orbital atherectomy (OA) in patients with heavily calcified coronary lesions undergoing PCI. : This systematic review and meta-analysis included all head-to-head published comparisons of coronary RA versus OA. Procedural endpoints and post-procedural clinical outcomes (30 days/in-hospital), were compared. RevMan 5.3 software was used for data analysis. : Seven retrospective observational investigations with a total of 4623 patients, including 3203 patients in the RA group and 1420 patients in the OA group, were incorporated. Compared with OA, the RA group was associated with a higher incidence of myocardial infarction at short-term follow-up (OR: 1.56, 95% CI: 1.07-2.29, = .02, = 0%). No difference was noted among other short-term post-procedural clinical outcomes including all-cause mortality, target vessel revascularization, or major adverse cardiac events. Among procedural complications, RA was associated with reduced coronary artery dissection and arterial perforation. Increased fluoroscopy time was observed in the RA cohort as compared with OA (MD: 4.78, 95% CI: 2.25-7.30, = .0002, = 80%). : RA was associated with fewer vascular complications, but at a cost of higher incidence of myocardial infarction and higher fluoroscopy time compared with OA, at short term follow-up. OA is a safe and effective alternative for the management of CAC.

Review
The optimal approach to deal with severe coronary artery calcification (CAC) in people with diabetes remains ill-defined. People with diabetes have a significant risk of developing severe vessel calcification and coronary artery disease (CAD). CAD is the leading cause of death in people with diabetes. Individuals with diabetes mainly present with severe multivessel stenosis, diffuse coronary calcification, and severe atherosclerosis, which are poor prognostic factors of revascularization procedures. Studies have shown that the revascularization of arteries in people with diabetes often results in worse outcomes than in people without diabetes. Coronary artery bypass grafting (CABG) has been recommended as the standard of care for people with DM and complex anatomic diseases, including left main CAD. However, percutaneous coronary intervention (PCI) is more acceptable to patients in clinical practice because of decreased trauma and rapid recovery. Severe CAC has traditionally been challenging for PCI and a frequent indication for surgical revascularization. This study aims to determine the effectiveness of orbital atherectomy (OA) in improving PCI outcomes in patients with diabetes and identify possible adverse effects that preclude its use. The study is reported according to PRISMA and analyzed according to Cochrane guidelines on synthesis without meta-analysis. A comprehensive literature search of EMBASE, Scopus, Web of Science, Cochrane Library, CINAHL, and MEDLINE was conducted for studies that utilized OA before PCI in people with diabetes. A reference list of the eligible articles was also screened. A narrative synthesis was done by representing the data on the effect direction plot, followed by vote counting. Eighteen studies were included in the analysis. Success rate/successful stent delivery was >90%, while freedom from angiographic complication and major adverse cardiovascular and cerebrovascular events (MACCE) were both >80% on the effect direction plot for people with diabetes and those without diabetes. People with diabetes had low event rates similar to those without diabetes. OA appears to be a viable treatment approach for people with diabetes. However, RCTs with a longer duration of follow-up are required to establish the appropriate treatment strategy for severe CAC in people with diabetes.

Meta-Analysis Review
PURPOSE
The need for specialty devices to improve the technical outcome of endovascular interventions is dependent on the rate of early failure in such procedures. This meta-analysis assessed procedural outcomes of such interventions to elucidate the rate of early procedural failures and the need for such specialty devices.
MATERIALS AND METHODS
MEDLINE and EMBASE were searched for contemporary studies (2000-2012) reporting procedural or short-term outcomes for revascularization of infrapopliteal atherosclerotic lesions. A random-effects metaanalysis was performed, which included post hoc comparisons among treatment groups.
RESULTS
A total of 42 studies with 52 treatment arms representing 3,660 unique patients were included. Technical success rates were higher with bare metal stents (BMSs; 98.6%) than with atherectomy (92.2%; P < .05) or percutaneous transluminal angioplasty (PTA; 91.2%; P = .01), and higher with drug-eluting stents (DESs) than with PTA (P < .001). DES use had higher primary patency rates than atherectomy (P < .05), BMS use (P < .001), and PTA (P < .01). The 30-day rate of target lesion revascularization was significantly higher with PTA (8.1%) than with BMSs (2.2%; P < .05) and DESs (1.1%; P < .05). Thirty-day rates of major unplanned amputation (range, 1.5%-4.4%) and mortality (range, 0.9%-3.3%) were comparable among treatment groups. Significant heterogeneity among studies was noted for most PTA outcomes. Publication bias was evident for most PTA and DES outcomes.
CONCLUSIONS
Early failure of percutaneous therapies in patients with infrapopliteal atherosclerotic lesions is device- and technique-dependent. Specialty devices designed to reduce technical failure rates may therefore be of benefit in this selected group of patients. Study results are confounded by inconsistent data reporting, heterogeneity of treatment effects, and publication bias.

Meta-Analysis Review
BACKGROUND
In this systematic review and meta-analysis, we aimed to compare drug-coated balloon (DCB) to drug-eluting stent (DES) angioplasty as a primary option in patients with femoropopliteal lesions in terms of primary patency and freedom from clinically driven target lesion revascularization (cdTLR) and major adverse limb events (MALE).
METHODS
A comprehensive literature search was performed using the PubMed and Embase databases. All studies written in English language and reporting data presenting a comparison between patients receiving primary percutaneous balloon angioplasty using the DCB versus primary percutaneous stenting with DES for native femoropopliteal lesions were included in this meta-analysis.
RESULTS
There were 984 patients with 1,078 femoropopliteal lesions, of which procedures with DCB and DES were performed in 514 and 564 lesions, respectively. Overall, majority patients were men with a mean age of 70.9 years, and there were no significant differences between the 2 groups regarding the cardiovascular comorbidities. With regards to the procedural strategy, there was significant heterogeneity in the DCB group. This included adjunctive procedures such as atherectomy besides the angioplasty of the target vessel, which was reported in 1 study as a part of 32.1% of the procedures in the DCB group. Provisional bare metal stents (pBMS) for residual stenosis and dissection were used in 4 studies with a percentage varying from 14.8 to 25.3%. Overall, at 1 year, all outcomes were similar for all the end points; however, where adjunctive procedures were performed (atherectomy + pBMS) in the DCB group, the outcomes were better (primary patency p.001, freedom cdTLR p.001, and freedom form MALE p.002). In studies where no adjunctive procedures were performed in the DCB group, the results favored the DES group for the primary patency (p.026) and freedom from cdTLR (p.044).
CONCLUSIONS
DES seems to be superior in terms of cdTLR and primary patency at 1 year when compared to the procedures performed solely with DCB. For DCB to achieve optimal results, further adjunctive procedures such as pBMS and atherectomy are needed. More studies are needed to confirm the superiority of the primary stenting with DES at the femoropopliteal segment.

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.

Meta-Analysis
AIMS
Optimal endovascular management of intermittent claudication (IC) remains disputed. This systematic review and meta-analysis compares efficacy and safety outcomes for balloon angioplasty (BA), bare-metal stents (BMS), drug-coated balloons (DCB), drug-eluting stents (DES), covered stents, and atherectomy.
METHODS AND RESULTS
Electronic databases were searched for randomized, controlled trials (RCT) from inception through November 2021. Efficacy outcomes were primary patency, target-lesion revascularization (TLR), and quality-of-life (QoL). Safety endpoints were all-cause mortality and major amputation. Outcomes were evaluated at short-term (<1 year), mid-term (1-2 years), and long-term (≥2 years) follow-up. The study was registered on PROSPERO (CRD42021292639). Fifty-one RCTs enrolling 8430 patients/lesions were included. In femoropopliteal disease of low-to-intermediate complexity, DCBs were associated with higher likelihood of primary patency [short-term: odds ratio (OR) 3.21, 95% confidence interval (CI) 2.44-4.24; long-term: OR 2.47, 95% CI 1.93-3.16], lower TLR (short-term: OR 0.33, 95% CI 0.22-0.49; long-term: OR 0.42, 95% CI 0.29-0.60) and similar all-cause mortality risk, compared with BA. Primary stenting using BMS was associated with improved short-to-mid-term patency and TLR, but similar long-term efficacy compared with provisional stenting. Mid-term patency (OR 1.64, 95% CI 0.89-3.03) and TLR (OR 0.50, 95% CI 0.22-1.11) estimates were comparable for DES vs. BMS. Atherectomy, used independently or adjunctively, was not associated with efficacy benefits compared with drug-coated and uncoated angioplasty, or stenting approaches. Paucity and heterogeneity of data precluded pooled analysis for aortoiliac disease and QoL endpoints.
CONCLUSION
Certain devices may provide benefits in femoropopliteal disease, but comparative data in aortoiliac arteries is lacking. Gaps in evidence quantity and quality impede identification of the optimal endovascular approach to IC.

Review
This review is intended to help clinicians and patients understand the present state of peripheral artery disease, appreciate the progression and presentation of critical limb ischemia/chronic limb-threatening ischemia, and make informed decisions regarding inflow and outflow endovascular revascularization and surgical treatment options within the context of current debates in the medical community. A controlled literature search was performed to obtain research on outcomes of critical limb ischemia patients undergoing complete leg revascularization for peripheral artery disease inflow and outflow disease. Data for this review were identified by queries of medical and life science databases, expert referral, and references from relevant papers published between 1997 and 2019, resulting in 48 articles. The literature review herein indicates that endovascular revascularization-including ballooning, stenting, and atherectomy-is an effective peripheral artery disease therapy for both above the knee and below the knee disease, and can safely and effectively treat both inflow and outflow disease. As such, it plays a leading role in the therapy of lower extremity artery disease.
