Comparative performance analysis of interventional devices for the treatment of ischemic disease in below-the-knee lesions: a systematic review and meta-analysis
AbstractThis meta-analysis aimed to evaluate the device performance of conventional balloon catheters (POBA), drug-coated balloons (DCB), bare-metal stents (BMS), and drug-eluting stents (DES) in below-the-knee (BTK) ischemic lesions with regard to lesion characteristics. Online searches of PubMed, Web of Science, and Cochrane databases (2010 –2019) were conducted for each of the test devices. Primary patency rates (pp) and major amputation rates 1 year after the use of each device were analyzed using a random-effects meta-analysis model. Meta-regression analysis was conducted to test associations between the outcomes a...

Mortality risk after use of a paclitaxel-coated stent in femoropopliteal peripheral artery disease
AbstractAlthough paclitaxel-based devices which demonstrated improved outcomes in the treatment of lower-extremity peripheral artery disease (PAD) have been used worldwide, Katsanos et al. reported a systematic review and summary-level meta-analysis of RCTs in which application of paclitaxel-based devices in the femoropopliteal artery was associated with an increased mortality risk. The purpose of this study was to describe the safety of endovascular therapy (EVT) using paclitaxel-coated stents for femoropopliteal disease by evaluating the mortality risk compared with patients treated with paclitaxel-free devices. A retros...

Optical coherence tomography-guided percutaneous coronary intervention: a review of current clinical applications
AbstractOptical coherence tomography (OCT) is an emerging high-resolution intravascular imaging modality that can provide physicians with critical information, thereby enabling precise characterization of plaque morphology and luminal geometry and facilitating pre-intervention lesion assessment. As OCT has a higher sensitivity for lipid-rich plaque characterization than intravascular ultrasound, vulnerable plaque detection by OCT has thus been investigated. By evaluating both the calcium thickness and arc, OCT can be the ideal method for determining both the indication and endpoint of rotational atherectomy for calcified l...

Difference in basic concept of coronary bifurcation intervention between Korea and Japan. Insight from questionnaire in experts of Korean and Japanese bifurcation clubs
AbstractThe coronary bifurcation intervention varies among countries due to the differences in assessment of lesion severity and treatment devices. We sought to clarify the difference in basic strategy between South Korea and Japan. A total of 19 and 32 experts from Korean (KBC) and Japanese Bifurcation Clubs (JBC), respectively, answered a survey questionnaire concerning their usual procedure of coronary bifurcation intervention. JBC experts performed less two-stent deployment in the left main (LM) bifurcation compared to KBC experts (JBC vs. KBC: median, 1 –10% vs. 21–30%,p <  0.0001) instead of higher perform...

A systematic review and meta-analysis of delayed coronary artery access for coronary angiography with or without percutaneous coronary intervention (PCI) in patients who underwent transcatheter aortic valve replacement (TAVR)
AbstractCoronary artery disease (CAD) and severe aortic valve stenosis frequently coexist. Given the progressive nature of CAD, silent or non-significant CAD may become symptomatic or functionally relevant years after TAVR. However, there is a paucity of data documenting the feasibility of either coronary angiography and/or PCI after TAVR. We systematically searched Medline, Pubmed, Embase, Cochrane database, Google Scholar, Science Direct, Web of Science, and conference abstracts from conception to March 2020 using OvidSP in TAVR patients undergoing coronary angiography with or without PCI at least 6  months after TAVR. ...

Drug-eluting stent thrombosis: current and future perspectives
AbstractOver the past 40  years, the safety and efficacy of percutaneous coronary intervention has dramatically improved by overcoming several challenges. The introduction of drug-eluting stent (DES) in particular was a major breakthrough in interventional cardiology. Compared to bare-metal stents, first-generation DES (G1 -DES) has dramatically reduced the rates of in-stent restenosis and subsequent target lesion revascularization. However, major safety concerns surrounding stent thrombosis (ST) emerged with G1-DES in clinical practice as a result of the high incidences of death, myocardial infarction, and repeat rev asc...

Practical utilization of cardiac computed tomography for the success in complex coronary intervention
AbstractPercutaneous coronary intervention (PCI) for complex lesions is still technically demanding and is associated with less favorable procedural parameters such as lower success rate, longer procedural time, higher contrast volume and unexpected complications. Because the conventional angiographic analysis is limited by the inability to visualize the plaque information and the occluded segment, cardiac computed tomography has evolved as an adjunct to invasive angiography to better characterize coronary lesions to improve success rates of PCI. Adding to routine image reconstructions by coronary computed tomography angio...

Clinical outcomes in nonagenarians undergoing transcatheter aortic valve implantation: a systematic review and meta-analysis
AbstractTo compare the risk of procedural complications and mortality after transcatheter aortic valve implantation (TAVI) in nonagenarians (age  ≥ 90 years) compared to younger patients (<  90 years). Although TAVI could be considered as a treatment option in nonagenarians, several previous studies have shown conflicting outcomes between nonagenarians and younger patients who underwent TAVI. We conducted a comprehensive literature search through PubMed and EMBASE to investigate the clinical outcomes of nonagenarians after TAVI. The outcomes of interest were short- and long-term mortality and procedural compli...
