: Femoro-popliteal PTA for the treatment of critical limb ischemia is frequently associated with unsatisfactory procedural success rates while directional atherectomy (DCA) has improved success rate since claudicant patients undergoing percutaneous treatment of femoro-popliteal obstructive disease. The aim of this prospective study is to evaluate the safety, efficacy and procedural success of DCA, at one year, in the percutaneous treatment of femoro-popliteal obstructive disease in patients with critical limb ischemia...

BACKGROUND: Heavy coronary artery calcification is responsible for stent underexpansion, which is associated with increased in-stent restenosis. Here we report a case in which optical coherence tomography (OCT) demonstrated that the metal component of an underexpanded stent previously implanted in a heavy calcified lesion had been completely removed after ablation with rotational atherectomy. CASE PRESENTATION: An 83-year-old man with exertional angina was referred to our hospital...

This study aims to evaluate occurrence, size, composition, and clinical significance of embolized debris during superficial femoral artery atherectomy using all commercially available atherectomy devices. Distal athero/thromboembolic events (DATE) are a universal phenomenon in lower extremity atherectomy procedures (LEAPs) due to the sheer volume of atheroma and the thrombus burden in peripheral arterial disease. Some of these events can be clinically significant. We prospectively gathered clinical and histopathological data on all commercially available atherectomy devices by using embolic protection devices (EPD) in every case...

OBJECTIVES: Coronary stent underexpansion is a known risk factor for in-stent restenosis and stent thrombosis. There are limited options once noncompliant balloons have failed to achieve optimal stent expansion. Excimer Laser Coronary Angioplasty with contrast medium injection is one possibility, but not readily available. Rotational atherectomy is an alternative, and has been described in case reports, but concerns exist regarding safety. METHODS: All consecutive patients undergoing rotational atherectomy for symptomatic in-stent restenosis due to stent underexpansion resistant to noncompliant balloon postdilatation between January 2005 and December 2015 were analysed...

OBJECTIVE: We describe a novel approach for the endovascular treatment of femoral artery occlusion as a result of Angio-Seal closure device deployment. BACKGROUND: Angio-Seal is the most commonly used vascular closure device following percutaneous coronary and peripheral catheterizations worldwide. A rare complication of Angio-Seal deployment is an occlusion of the femoral artery leading to limb ischemia requiring revascularization. Given its unique ability to cut both atherosclerotic plaque and the Angio-Seal anchor with a collagen plug at operator-directed planes, TurboHawk/HawkOne atherectomy device can be a fast and effective approach to treat Angio-Seal-associated femoral artery occlusions...

AIMS: We investigated the impact of lesion calcification on angiographic outcomes after Absorb everolimus-eluting bioresorbable vascular scaffold (BVS) implantation in comparison with those after cobalt chromium everolimus-eluting stent (CoCr-EES) implantation. METHODS AND RESULTS: The present post-hoc analysis of the ABSORB Japan randomized trial compared post-procedure and 13-month angiographic outcomes between patients implanted with BVS and CoCr-EES based on the presence or absence of calcification, excluding extremely heavily calcified lesions or lesions requiring rotational atherectomy...

OBJECTIVES: We aimed to illustrate one of the mechanisms of rotational atherectomy burr entrapment in a coronary stent where the burr was rolled up in the stent's struts. METHODS: We report a case where the treatment of a mid right coronary artery (RCA) lesion using a rotational atherectomy device was attempted. During the procedure, the burr suddenly got stuck in a freshly implanted stent in the distal RCA. Despite several attempts and maneuvers, we were unable to pull back the burr...

OBJECTIVES: We evaluated the relationship between gender and angiographic and clinical outcomes in patients with severely calcified lesions who underwent orbital atherectomy. BACKGROUND: Female gender is associated with increased risk of adverse clinical events after percutaneous coronary intervention (PCI). Severe coronary artery calcification increases the complexity of PCI and increases the risk of adverse cardiac events. Orbital atherectomy is effective in plaque modification, which facilitates stent delivery and expansion...

Despite significant advances in treatment of coronary artery disease and improvements in interventional devices and techniques, the subset of obstructive calcified coronary artery disease remains challenging to treat. Percutaneous treatment of these lesions results in increased rates of procedural complications, as well as a higher risk of stent underexpansion and malapposition. This is associated with higher rates of restenosis, target lesion revascularization (TLR), and major adverse cardiac events (MACE)...

Endovascular management of peripheral artery disease was until recently limited to percutaneous balloon angioplasty, atherectomy, stent grafts, and bare-metal stents. These therapies have been valuable, but plagued by high restenosis and revascularization rates. Important progress has been made with the introduction of combination devices, including drug-eluting stents and drug-coated balloons (DCB), designed to combat restenosis by locally delivering anti-proliferative drugs. In particular, promising clinical performance has been seen with the Medtronic IN...

BACKGROUND: This study evaluated the feasibility, safety, and effectiveness of endovascular interventions for common femoral artery (CFA) occlusive disease. METHODS: Using a prospectively maintained multicenter database, we analyzed outcomes in 167 consecutive patients who underwent percutaneous CFA interventions for Rutherford class 3 to class 6 (R3-R6) disease. The standardized treatment approach included primary percutaneous transluminal angioplasty (PTA) only, atherectomy + PTA, and provisional stenting...

Provisional use of rotational atherectomy (RA) is indicated for procedural success in heavily calcified lesions. In the current study, RA use at three high volume percutaneous coronary intervention (PCI) centers between 2005 and 2013 was 1.4%. MACE rate was 17.8% at median follow-up of 22 months. Peripheral vascular disease (PVD), diabetes mellitus (DM), acute coronary syndrome (ACS), and SYNTAX > 23 were found to be independently associated with MACE. With increasing complexity of disease and SYNTAX score, there is usually an increase in severity of calcification and need for atherectomy...

We report a case of percutaneous coronary intervention in a bifurcation lesion involving left circumflex (LCx) artery and 2 major posterolateral (PL) arteries. The target LCx had diffuse long and severely calcified lesion with the acute takeoff angle from the left main. Despite adequate lesion preparation with rotational atherectomy and balloon angioplasty, the stent was not deliverable, even with deep intubation of 7Fr-guiding catheter. Conventional use of guiding extension catheter (GEC) would have required removal of a wire from at least one PL because of the device interference in the GEC...

While rotational atherectomy (RA) is used for complex lesions in percutaneous coronary intervention, there are several contraindications such as unprotected left main stenosis or left ventricular dysfunction. We previously reported that the incidence of in-hospital complications was significantly greater in off-label as compared to on-label use RA. However, the mid-term clinical outcomes between off-label and on-label RA have not been investigated. The purpose of this study was to compare the mid-term clinical outcomes between off-label (n = 156) and on-label RA (n = 94)...

Although performing rotational atherectomy (RA) requires guidewire exchange for the dedicated guidewire, RotaWire guidewire (Boston Scientific) exhibits much lower performance than conventional guidewire. Consequently, there are times when RotaWire cannot be advanced past the lesion independently or using a microcatheter exchange technique, rendering RA impossible. We present a case of a heavily calcified, device-uncrossable, and non-expansible chronic total occlusion lesion successfully revascularized with RA over RG3 guidewire (Asahi Intecc), which has a length of 330 cm, hydrophilic coating, and a 0...
