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...

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...

BACKGROUND: The usage of rotational atherectomy (RA) is growing in the current percutaneous coronary intervention (PCI) because of the expansion of PCI indication to more complex lesions. However, the complications after RA have been linked to procedure-related morbidity and mortality. The purpose of this study was to investigate the incidence and determinants of complications in RA using a large nationwide registration system in Japan (J-PCI). METHODS AND RESULTS: The primary composite outcome of this study was defined as the occurrence of in-hospital death, cardiac tamponade, and emergent surgery after RA...

OBJECTIVES: The aim of this study was to compare outcomes of bailout and planned rotational atherectomy (RA) in the treatment of calcified coronary lesions. BACKGROUND: Current guidelines recommend RA as a bailout procedure for calcified or fibrotic lesions that cannot be adequately dilated before stenting. Nonetheless, planned RA is sometimes performed in certain challenging anatomies. METHODS: Data of patients treated with RA between 2002 and 2014 at a single-center registry were retrospectively analyzed...

AIMS: The aim of this multicentre study was to investigate the in-hospital and midterm outcomes of rotational atherectomy (RA) followed by metallic stent implantation. METHODS AND RESULTS: Between 2002 and 2013, 1,176 de novo lesions with calcified coronary lesions treated by RA and metallic stent implantation at nine institutions were assessed. Patients with ST-segment elevation myocardial infarction (STEMI) within 30 days, cardiogenic shock before the procedure, lesions with thrombus, and in-stent restenosis were excluded from the current analysis...

OBJECTIVES: To study the long-term outcomes of rotational atherectomy (RA) for chronic total occlusion (CTO) percutaneous coronary intervention (PCI). BACKGROUND: There is little evidence on the incidence, procedural results and long-term outcomes of RA for CTO PCI. METHODS: This registry included data from consecutive patients undergoing CTO PCI at four specialized centers. Major adverse cardiac events (MACE: cardiac death, target-vessel myocardial infarction and ischemia-driven target-vessel revascularization) on follow-up were the primary endpoint...

BACKGROUND: Percutaneous coronary intervention (PCI) procedures are increasingly performed on complex tortuous and heavily calcified coronary lesions. The GuideLiner® catheter (Vascular Solutions, Inc. Minneapolis, MN) is a rapid exchange guide catheter extension system. There is paucity of data about the efficacy of this device in complex PCI. Therefore, we aim to report the indications, success, and efficacy of GuideLiner use in treating complex lesion subset in the present study. METHODS: We collected data from all patients in whom the GuideLiner was used to facilitate PCI between April 1, 2011 and December 31, 2014 at a tertiary referral center in Toronto, Canada...

Preprocedural planning and advanced imaging is vital to achieve a consistent and high level of success for complex coronary chronic total occlusion (CTO) revascularization. Various practice patterns exist around the world when performing coronary artery CTO revascularization. This case report highlights a fusion of global practices in CTO intervention and integration of advanced imaging to achieve successful revascularization.

Intercoronary communications (ICC) or open-ended coronary circulation is rare. We describe intercoronary communication in a case of chronic total occlusion, and discuss the pathophysiological and clinical significance of these rare entities. The present case also demonstrates the anatomical presence of ICC despite angiographic absence for the first time using CT coronary angiography.

Despite permanent improvement in success rate and technical developments, chronic total occlusion (CTO) remains undertreated by percutaneous coronary intervention (PCI). Dedicated CTO operators from Japan, Europe and USA perform these procedures with success rate beyond 90%, but there is still huge gap between this group of specialists and broader population of PCI operators. Recently proposed CTO scores can be used for patients' selection according to the CTO operators' experience. Patients with low CTO Score values may be suitable for less experienced operators at the beginning of the CTO PCI learning curve, while more complex CTOs (higher CTO Score values) should be differed to CTO experts...

Despite the continuing developments of improved medical devices and increasing operator expertize, coronary chronic total occlusion (CTO) remains as one of the most challenging lesion subsets in interventional cardiology. Percutaneous coronary intervention (PCI) of CTO is a complex procedure carrying the risk of complications that are responsible for significant morbidity and mortality. The complications can be classified as coronary (such as coronary occlusion, perforation, device embolization, or entrapment); cardiac non-coronary (such as periprocedural myocardial infarction); extra cardiac (such as vascular access complications, systemic embolization, contrast-induced nephropathy, and radiation-induced injury)...

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...

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...

REVIEW
Paul N Fiorilli, Saif Anwaruddin
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)...
