CTO lesions resisting balloon crossing are located in moderate/severe tortuous coronary arteries contain more moderate/severe calcification burden and carry a higher J-CTO score as compared with balloon crossable CTO lesions. CTO lesions resisting balloon crossing do not constitute a homogenous group. In 25% of the patients, the resisting CTO was caused by stent restenosis and thrombus is an integral component of CTO in addition to calcium and fibrosis. The excimer laser and rotational/orbital atherectomy are among useful debulking technologies capable of creating a "pilot recanalization channel" in the CTO that enables completion of the revasularization...

Arteriotomy closure devices (ACDs) are routinely used for vascular closure during invasive cardiovascular procedures. They decrease time to hemostasis as well as length of stay. Major complications such as arterial ischemia and occlusion can be encountered in a minority of patients. We are describing a series of 3 patients with access site closure using Angio-Seal after coronary angiography who developed intermittent claudication within 2-3 weeks of follow-up. Access site thrombosis/stenosis in the CFA was found in all the three cases...

Coronary chronic total occlusion (CTO) intervention remains one of the most challenging domains in interventional cardiology. Due to the technical challenges involved and potential procedural complications, CTO percutaneous coronary intervention (PCI) attempt and success rates remain less than standard PCI. However, the use of several adjunctive tools such as intravascular ultrasound, optical coherence tomography, rotational atherectomy, orbital atherectomy, excimer laser coronary atherectomy and percutaneous left ventricular assist device may contribute to improved CTO PCI success rates or provide better hemodynamic assessment of CTO lesion (i...

OBJECTIVES: To report adverse event rates after rotational atherectomy (RA) with contemporary drug-eluting stent (DES) implantation and compare RA to cutting balloon (CB) angioplasty and balloon-only angioplasty (BA) in the all-comers ADAPT-DES trial. BACKGROUND: Percutaneous coronary intervention (PCI) of calcified lesions is increasingly common and is associated with a high risk of adverse events. RA can ablate calcified plaque and facilitate stent delivery; however, in conjunction with first-generation DES, RA was not superior to BA alone in regard to adverse events...

Preprocedural lesion length and ankle-brachial indices (ABI) synergistically predict 12-month patency and repeat revacularization in claudicants treated with bare metal nitinol stents for femoropopliteal disease. This predictive length-ABI model will permit broader evidence-based indirect comparisons of newer femoropopliteal approaches such as drug eluting balloon treatment with or without atherectomy. The length-ABI model is a step to supplement and supplant randomized controlled trials with indirect comparisons as the necessary evidence source expediting innovation and optimizing personalized endovascular therapy for infrainguinal obstructive peripheral arterial disease...

BACKGROUND: Target-lesion revascularization (TLR) and loss of patency remain high following treatment of in-stent restenosis (ISR) of the femoropopliteal (FP) artery. Excimer laser atherectomy (ELA) is effective in reducing TLR and improves patency at 6-month and 1-year follow-up when compared with balloon angioplasty (PTA). The long-term sustainability of these early results is unknown. We present a retrospective analysis from our center on the 5-year outcomes of ELA in the treatment of ISR of the FP arteries...

Distal embolization is a common occurrence with peripheral arterial interventions and is more frequent with the use of atherectomy devices. We report the first case of JetStream atherectomy (Boston Scientific, Maple Grove, MN) with the use of the novel WIRION embolic protection system filter. The procedure was performed successfully with no distal embolizations beyond the filter and with no complications in the delivery or retrieval of the filter. The pros and cons of the off label use of this filter with JetStream atherectomy are discussed...

This analysis compared the angiographic outcomes of patients treated with orbital atherectomy for calcified common femoral artery (CFA) and superficial femoral artery (SFA) disease. The ideal revascularization strategy for CFA disease is unknown. Endarterectomy has been considered the standard of care for CFA disease for over 50 years. Endovascular intervention is becoming more commonly used to revascularize the CFA given the advances in technology and the less invasive nature of the procedure. Patient demographics, lesion characteristics, and procedure data for all CONFIRM patients with at least one CFA lesion location ( n=147 patients; n=200 lesions) were compared to patients with at least one SFA lesion location ( n=1508 patients; n=2367 lesions)...

PURPOSE OF REVIEW: Critical limb ischemia (CLI) is associated with significant morbidity, mortality, and increased health care expenses. Revascularization has a central role in the treatment of CLI. Following publication of BASIL (bypass versus angioplasty in severe ischemia of the leg) trial a decade ago, an "endovascular first" approach had gained momentum and the technologies available for endovascular therapy have exponentially increased. Both the development of technology and technique, highlighted in this review, have allowed operators to treat complex infrapopliteal lesions which are central to CLI pathology...
