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...

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)...

BACKGROUND: Balloon uncrossable lesions can be challenging to treat, requiring specialized techniques and equipment. METHODS: We examined the prevalence, clinical and angiographic characteristics, management and procedural outcomes of balloon uncrossable lesions in a multicenter chronic total occlusion (CTO) percutaneous coronary intervention (PCI) registry. RESULTS: Between 2012 and 2016, 718 CTO PCIs (in which the occlusion was successfully crossed with a guidewire) were performed in 701 patients at 11 US centers...

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...

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)...

Coronary stent delivery can be extremely challenging in tortuous and calcified lesions especially when radial approach is chosen. Guide extension catheter is a useful tool for overcoming the inherent difficulties arising by the use of radial access in complex percutaneous interventions. We describe a technique for guide extension catheter system advancement by presenting two cases. This was performed stepwise by repeated distal balloon anchoring in the coronary artery of interest.

We assessed the very long-term follow-up of a large cohort of unselected patients treated with coronary rotational atherectomy (RA). All 143 patients who underwent RA at our institution from 2000 to 2013 and with complete baseline and follow-up information were analyzed in a retrospective manner. Major adverse cardiac events (MACE) were defined as the composite of target vessel revascularization (TVR), acute myocardial infarction, and all-cause mortality. The mean follow-up was 8.2 years. The 10-year cumulative incidence of MACE for all patients was 57...

A patient was referred to us for Canadian Cardiovascular Society class III refractory angina. He was found to have in-stent restenosis within three layers of underexpanded stents implanted in 2004, 2011, and 2014. Rotational atherectomy safely yielded stent strut ablation (reduced to one layer), lesion expansion, and very good angiographic and physiologic results.

The Rendezvous technique, which requires bidirectional wiring, is one of the useful methods for improving the success rate of recanalization for chronic total occlusion (CTO) in the field of peripheral intervention. Recently, advanced new devices for percutaneous coronary intervention have enabled us to perform the Rendezvous technique for peripheral as well as for coronary CTO lesions. We used the Intracoronary Rendezvous technique to perform angioplasty for coronary CTO. "Intracoronary Rendezvous" means that Rendezvous was achieved within the CTO lesion...

OBJECTIVES: This study sought to assess the impact of chronic total occlusion (CTO) on long-term prognosis in patients with ischemic cardiomyopathy. BACKGROUND: The presence of concomitant CTO in a nonculprit lesion in acute coronary syndromes is associated with worse prognosis. Coronary artery disease is the main cause of heart failure and in many cases at least 1 CTO is observed. METHODS: The study included all patients with systolic heart failure who underwent elective coronary angiography and were registered from January 2009 to December 2014 in the ongoing single-center COMMIT-HF (COnteMporary Modalities In Treatment of Heart Failure) registry (NCT02536443)...

We report a case of successful computed tomography-guided percutaneous revascularization of a chronically occluded right coronary artery using a wearable, hands-free computer with a head-mounted display worn by interventional cardiologists in the catheterization laboratory. The projection of 3-dimensional computed tomographic reconstructions onto the screen of virtual reality glass allowed the operators to clearly visualize the distal coronary vessel, and verify the direction of the guide wire advancement relative to the course of the occluded vessel segment...
