BACKGROUND: Development of the CrossBoss and Stingray devices for antegrade dissection and reentry (ADR) of chronic total occlusions has improved historically suboptimal outcomes. However, the outcomes, safety, and failure modes of the technique have to be studied in a larger patient cohort. This preplanned substudy of the RECHARGE registry (Registry of CrossBoss and Hybrid Procedures in France, the Netherlands, Belgium and United Kingdom) aims to evaluate the value and use of ADR and determine its future position in contemporary chronic total occlusion intervention...

The aim of this review is to highlight the technical details and the scientific data on percutaneous coronary interventions (PCIs) in chronic total occlusion (CTO) performed by transradial approach (TRA). Transfemoral approach (TFA) is commonly regarded as the standard for CTO PCI, but there are a growing number of CTO recanalization procedures performed by TRA. We discuss the relevant technical details to approach a CTO by transradial access, especially the compatibility of various CTO recanalization techniques with specific guiding catheter sizes...

Retrograde dissection re-entry can cause pericardial trauma of sufficient degree to lead to the development of an auto-immune postpericardial injury syndrome. Clinical suspicion for this condition should be high in the event of fever, symptoms, pericardial/pleural effusion, and pleuritic chest pain following chronic total occlusion (CTO) Post cardiac injury syndromes (PCI).

Total occlusion of a coronary artery for more than 3 months is defined as chronic total occlusion (CTO). The goal of this study was to develop a risk score in predicting failure or success during attempted percutaneous coronary intervention (PCI) of CTO lesions using antegrade approach. This study was based on retrospective analyses of clinical and angiographic characteristics of CTO lesions that were assessed between February 2012 and February 2014. Success rate was defined as passing through occlusion with successful stent deployment using an antegrade approach...

Up to 50% of patients presenting with ST elevation myocardial infarction (STEMI) are found to have multivessel coronary artery disease. These patients have a worse prognosis compared with the overall STEMI population. Two revascularization strategies are possible for these patients: treating the infarct-related artery percutaneous coronary intervention (IRA-PCI) only or achieving Complete revascularization (CR), either through an immediate multivessel PCI during the index angiography or during a second-staged procedure...

Antegrade crossing is the most common approach to chronic total occlusions (CTOs). However, it is sometimes difficult to penetrate the proximal hard cap with guidewires, especially in the case of CTOs of anomalous coronary arteries because of a lack of support. Herein, we describe a novel, modified reverse controlled antegrade and retrograde subintimal tracking (CART) technique in which the dissection reentry was intentionally created in the proximal segment of the vessel, not within the occluded segment, using retrograde guidewire and the aid of an antegrade balloon...
