BACKGROUND: Correlations between the ACC/AHA coronary lesion classification and clinical outcomes in the contemporary percutaneous coronary intervention (PCI) era are not well established. METHODS: We analyzed clinical characteristics and outcomes according to ACC/AHA lesion classification (A, B1, B2, C) in 13,701 consecutive patients from the Melbourne Interventional Group (MIG) registry. Patients presenting with STEMI, cardiogenic shock and out-of-hospital cardiac arrest were excluded...

Retroperitoneal hemorrhage from iliac artery injury is a potentially serious complication of vascular interventional procedures leading to hemorrhagic shock and death if not diagnosed early and treated promptly. We report a 70-year-old male admitted to our facility with non-ST-elevation myocardial infarction, whose heart catheterization revealed left anterior descending artery (LAD) with 80% proximal, 95% mid and 100% distal disease. The left circumflex and right coronary arteries were 100% occluded proximally and received collaterals from the LAD...

AIMS: Patients undergoing percutaneous coronary intervention (PCI), with a history of coronary artery bypass grafting (CABG), may be at increased risk for mortality and repeat revascularization, compared with patients without prior CABG. In this post-hoc analysis of the ORBIT II trial, safety and efficacy of coronary orbital atherectomy (OA) to modify severe coronary artery calcium, prior to stent placement, was evaluated in subjects based on history of CABG. METHODS AND RESULTS: Comorbidities: diabetes, dyslipidemia, hypertension, and history of myocardial infarction (MI) were more prevalent in the CABG group...

Intravascular ultrasound (IVUS) is mainly used in PCI to treat complex lesions, such as left main bifurcation, chronic total occlusion and calcified lesions. Although IVUS yields useful information such as the presence of napkin-ring calcification, the role of IVUS in rotational atherectomy (RA) is not fully appreciated. Recently, since the deliverability and crossability of IVUS catheters have improved, IVUS should be attempted before RA. Even if the IVUS catheter cannot cross the lesion, IVUS provides information just proximal to the target lesion, which would be useful in the selection of the appropriate guidewire and burr size...

Longitudinal rotational atherectomy of metal struts is well described as bail-out strategy to treat undilatable instent restenosis. Ablation of metal stent struts jailing the ostium of a major side branch in a coronary bifurcation is not described. In the current report, we describe a case of "transverse" rotational atherectomy to treat a failure of culotte stenting in a left main stem bifurcation. We document for the first time in vivo and in man the effect of this strategy using optical coherence tomography...

AIM: The incremental cost of peripheral orbital atherectomy system (OAS) plus balloon angioplasty (BA) versus BA-only for critical limb ischemia was estimated. MATERIALS & METHODS: A deterministic simulation model used clinical and healthcare utilization data from the CALCIUM 360° trial and current cost data. Incremental cost of OAS + BA versus BA-only included differential utilization during the procedure and adverse-event costs at 3, 6 and 12-months. RESULTS: For every 100 procedures, incremental annual costs to the hospital were USD$350,930 lower with OAS + BA compared with BA-only...

The impact of lesion complexity on long-term vascular response to cobalt-chromium everolimus-eluting stent (CoCrEES) remains unclear. We sought to evaluate them using optical coherence tomography (OCT). A total of 47 patients with 58 lesions treated only with CoCrEES and no target-vessel events within 5 years after implantation were prospectively enrolled and underwent 5-year follow-up OCT. Quantitative parameters and qualitative characteristics of the neointima were evaluated using multilevel logistic or linear regression models with random effects at three levels: lesion, cross-section (CS), and strut...

Severe coronary artery calcification (CAC) increases the complexity of percutaneous coronary intervention (PCI) by inhibiting optimal stent expansion, leading to an increased risk of death, myocardial infarction, repeat revascularization, and stent thrombosis. Coronary atherectomy modifies and debulks calcified plaque to facilitate PCI. Although there is no clear consensus, and further studies are needed, the decision to perform atherectomy should be based upon the presence of fluoroscopic CAC or with the use of intravascular imaging...

We present the case of an 81-year-old female with flush occlusion of the superficial femoral artery (SFA) and percutaneous transluminal angioplasty. Initially, the antegrade approach failed due to flush occlusion without stump. Hard, round surfaced, calcific, and eccentric plaque of the ostium of SFA was also present, which involved distal common femoral artery (CFA). Thus, we successfully used a Frontrunner catheter for retrograde reentry at the lower position of the CFA. Various treatment strategies involving Frontrunner and atherectomy devices could make percutaneous procedures possible in femoropopliteal occlusive disease, involving the CFA...

INTRODUCTION: The efficacy of heparin based flush solutions in rotational atherectomy (RA) has not been validated. Recently, a single center study demonstrated the feasibility of an alternative flush solution with 10,000U of unfractionated heparin (UFH) in 1L of normal saline. We aimed to evaluate the safety and efficacy of an alternative flush solution intermittently utilized at our institution. METHODS: We retrospectively identified 150 patients undergoing RA over a three year period...

This paper will discuss the results from the most recent randomized trials and large registries for DCB's and atherectomy, and the drawbacks of these 2 therapeutic options. It will also discuss the results of combination therapy in complex femoropopliteal lesions. Several studies indicate that combining atherectomy and DCB yields better outcomes in complex calcified lesions, but the only randomized pilot study could not demonstrate a benefit of combination therapy in the mid-term follow-up. Larger, randomized studies are needed to define the role of atherectomy followed by DCB angioplasty further...

INTRODUCTION: Conventional therapies for transcatheter treatment of patients with infrainguinal obstructive disease remain compromised by high restenosis rates. Drug-coated balloons (DCB) offer a novel therapeutic alternative targeting the source of neo-intimal hyperplasia, without the need for a permanent endovascular scaffold and their inherent limitations. EVIDENCE ACQUISITION: A systematic research of the medical databases (Pubmed) has been conducted for this up-to-date review...

OBJECTIVE: We assess the angiographic and clinical outcomes of patients with a history of coronary artery bypass graft (CABG) surgery who underwent orbital atherectomy for the treatment of severely calcified coronary lesions. BACKGROUND: The presence of severe coronary artery calcification (CAC) increases the complexity of percutaneous coronary intervention (PCI) and is associated with worse clinical outcomes. Patients with a history of CABG who undergo PCI often have comorbidities and are at higher risk for ischemic complications...

An 83-year-old man presented with recurrent acute coronary syndrome (ACS) at the left main coronary artery (LMCA) complicated with ostial chronic total occlusion (CTO) in the right coronary artery (RCA) (RCA-CTO). At the first LMCA-ACS approximately 1 year earlier, he had undergone LMCA-crossover stenting with a biolimus-eluting stent in the presence of RCA-CTO. At the second LMCA-ACS, we angiographically confirmed severe in-stent restenosis in the distal LMCA, in addition to angled severe stenosis in the just proximal LCx, and performed primary PCI for the LMCA bifurcation lesion under intra-aortic balloon pumping support...
