REVIEW
Pasi P Karjalainen, Wail Nammas
Chronic total occlusion (CTO) is a challenging subset of coronary artery disease that is commonly encountered in real-world practice; it is associated with worse long-term prognosis. Observational studies suggest that percutaneous coronary intervention (PCI) for CTO is associated with reduction in myocardial ischemia and improvement in quality of life and left ventricular function. Some observational studies suggested that CTO-PCI is associated with improvement of the 'hard' clinical endpoints; others did not...

OBJECTIVES: To determine whether successful percutaneous coronary intervention (PCI) using drug-eluting stents (DESs) have beneficial effects on long-term outcomes in patients with chronic total occlusions (CTOs) compared with failed PCIs for CTOs. BACKGROUND: Several observational studies have evaluated the long-term clinical outcomes of successful PCIs using DESs for CTOs. However, the results of these studies were inconsistent and inconclusive. METHODS: We searched five online electronic databases to identify all the publications assessing the long-term outcomes of successful and failed PCIs using DESs for CTOs...

With the recent increase in complex coronary interventions including percutaneous coronary intervention (PCI) for chronic total occlusions and complex higher risk (and indicated) patients, the spectrum of potential periprocedural complications and their prompt management has become even more relevant. Vascular access-related problems remain the most prevalent of all PCI complications and with randomized controlled trial data from over 20,000 patients supporting the superiority of radial over femoral access in reducing bleeding and vascular complications, a default radial strategy should be promoted...

PURPOSE OF THE REVIEW: Chronic total occlusions (CTOs) are found in about a third of patients with coronary artery disease (CAD) and can pose a significant challenge during percutaneous revascularization. However, advances in CTO percutaneous coronary intervention (PCI) strategies, devices, and algorithms have led to significant improvements in successful treatment of CTOs. This review summarizes current management of CTOs in the context of modern PCI techniques and current evidence. RECENT FINDINGS: The hybrid algorithm now provides a standardized, teachable approach to CTO PCI, and success rates are approximately 90% in experienced hands...

Covered stents are indicated for coronary perforations, but they may seal off major side branches in that process. We report the successful sealing of an ostial left main perforation, induced by a guide catheter in the course of a retrograde approach to treat a chronic total occlusion (CTO) of the right coronary artery (RCA) in a 76year old woman with prior CABG. The implanted Papyrus covered stent, however, overlapped the left main bifurcation and occluded the non-grafted circumflex artery (CX) resulting in acute ischemia...

Despite improvements in guidewire technologies, the traditional antegrade wire escalation approach to chronic total occlusion (CTO) recanalization is successful in only 60-80% of selected cases. In particular, long, calcified, and tortuous occlusions are less successfully approached with a true-to-true lumen approach. Frequently, the guidewire tracks into the subadventitial space, with no guarantee of distal re-entry into the true lumen. The ability to manage the subadventitial space has been a key step in the tremendous improvement in success rates of contemporary CTO percutaneous coronary intervention (PCI), whether operating antegradely or retrogradely...

OBJECTIVES: To evaluate the contribution of chronic total occlusion (CTO)-related SYNTAX score (SS) to the overall SS for patients with CTO and compare the traditional SS to a simplified variant. The SS algorithm assigns CTO lesions a greater weight (5× points) than non-CTO lesions (50% to <100% diameter stenosis; 2× points). METHODS: We calculated the SS and the simplified SS (2× points also to CTO lesions) for 4356 patients from the angiographic substudy of the Acute Catheterization and Urgent Intervention Triage StrategY (ACUITY) trial...

We aimed to determine clinical outcomes 1 year after successful chronic total occlusion (CTO) PCI and, in particular, whether use of dissection and re-entry strategies affects clinical outcomes. Hybrid approaches have increased the procedural success of CTO percutaneous coronary intervention (PCI) but longer-term outcomes are unknown, particularly in relation to dissection and re-entry techniques. Data were collected for consecutive CTO PCIs performed by hybrid-trained operators from 7 United Kingdom (UK) centres between 2012 and 2014...

BACKGROUND: Differences in stent platform, polymer coatings, and antirestenotic drugs among the current in use second-generation drug-eluting stents (G2-DESs) may induce significant variations in neointimal response and vascular healing, which may impact the prevalence of neoatherosclerosis (NA) and morphological appearance of the restenotic tissue. METHODS AND RESULTS: Utilizing Optical frequency domain imaging, two independent reviewers, retrospectively compared the prevalence of neoatherosclerosis (NA), and the morphological differences, and tissue characteristics of 50 G2-DESs in-stent restenosis (ISR) lesions (35 everolimus-eluting stent [22 cobalt-chromium (CoCr), 13 platinum-chromium (PtCr)], and 15 biolimus-eluting stent [BES]) implanted liberally in unrestricted coronary lesions...

In minimal invasive cardiac surgery (MICS), the surgeon is missing haptic feedback of the guide wire for navigation through the vessels. A wide range of guide wires with various properties and performance characteristics are available to reduce the risk of complications during the intervention. This paper presents a force sensing guide wire for cardiac catheterization, which provides the surgeon a haptic feedback on the guide wire tip. Three conventional wires for the recanalization of chronic total coronary occlusions (CTO) are investigated and general design requirements for the force sensing guide wire are determined...

OBJECTIVES: Although coronary chronic total occlusions (CTOs) are treated with percutaneous coronary intervention (PCI) to improve symptoms, studies demonstrating symptom improvement have been mostly limited to questionnaire responses. The current study assessed for changes in peak oxygen uptake during cardiopulmonary exercise testing after CTO-PCI. METHODS: Patients with heart failure or angina symptoms referred for CTO-PCI were prospectively enrolled. The primary outcome of the study was improvement in peak oxygen uptake during cardiopulmonary exercise (CPX) testing 5 months after CTO-PCI...
