The retrograde technique has significantly improved the success of percutaneous treatment of chronic total occlusions (CTO). After crossing a collateral channel, creating a connection between the anterograde and retrograde systems is key. The most common technique for this is reverse controlled antegrade and retrograde subintimal tracking (reverse CART). This technique involves inflating a balloon over…
JR-CTO Score for Percutaneous Treatment of Chronic Total Occlusions via Retrograde Approach
Technological advancements and technique improvements have significantly enhanced the success rate of percutaneous interventions for treating chronic total occlusions (CTO). Angiographic scores and CTO-PCI algorithms are valuable tools that help us select the optimal strategy when planning these procedures. The retrograde strategy, specifically, has proven beneficial in addressing complex CTOs. However, standardized tools to predict…
ERCTO Registry: Chronic Total Occlusion Treatment Outcomes
Chronic total occlusion (CTO) affect up to 20% of patients undergoing angiographic diagnostic tests. During the last two decades, recanalization technique refinement, the development of specific devices and operator skill improvement have elevated procedural success rate up to 90%. However, there are still particular complications such as collateral perforation and access site complications. This is…
ERCTO Registry: Current Results for Percutaneous Treatment of Chronic Total Occlusions
Chronic total occlusions (CTO) occur in up to 20% of patients undergoing diagnostic angiographic studies. Over the past two decades, the optimization of recanalization techniques, the development of new specialized devices, and improvement in operator skill have contributed to an increased procedural success rate, reaching 90%. However, specific complications such as collateral perforation and access…
Contemporary Outcomes of CTO PCI in Europe: The ERCTO Registry
Roughly 20% or coronary angiographies show some form of chronic total occlusion (CTO), and this figure is twice as high for diabetic patients or those with cardiac failure and reduced ejection fraction (EF). CTO percutaneous intervention (PCI) has experienced a significant growth thanks to the development of new techniques and dedicated material. However, a considerable…
Dissection and Re-Entry Technique in Chronic Total Occlusions: Data from the PROGRESS-CTO Registry
The antegrade dissection and re-entry (ADR) technique is considered essential for the management of chronic total occlusions (CTO). It serves as the primary option in some protocols for complex and extensive lesions or as a backup strategy in case of failure with other initial strategies. Dissection techniques include guided methods such as scratch and go,…
Retrograde Approach to Chronic Total Occlusions: Techniques and Outcomes According to the PROGRESS-CTO Registry
The retrograde approach for recanalizing chronic total occlusions (CTO) has undergone significant evolution since its introduction in 1990, improving both in terms of techniques and specialized materials. The increased skill applied to this strategy has resulted in increased success rates for the treatment of CTO in sites with an adequate volume of procedures. Given the…

EuroCTO: Safety and Benefit at 3 Years
Chronic total occlusions (CTOs) account for approximately 15-20% of patients with stable coronary artery disease. This field has seen various advances regarding treatment, leading to an improvement in the success rate of procedures. According to registries and randomized studies, the main indication for percutaneous coronary intervention (PCI) of CTO should be based more on clinical…
Relationship between Distal Vessel Quality and Outcomes in the Treatment of Chronic Total Occlusions
Percutaneous treatment of chronic total occlusions has increase, and has become a a more habitual therapeutic challenge. However, there is limited information on distal vessel quality and its association with outcomes and techniques. This variable appears to be excluded form CTO scores, except for the RECHARGE (REgistry of CrossBoss and Hybrid procedures in FrAnce, the…
Calcified Nodules and the Importance of OCT Categorization prior PCI
TLR associated factors in patients with calcified nodules. Patients with complex cardiomyopathies undergoing percutaneous coronary intervention are increasingly common, as is the case for calcified lesions and calcified nodules (CN). Procedure complexity not only involves planning, but also establishing patient prognosis, taking into consideration the fact that most target vessel events occur at long term…
