The success of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) depends on the execution of bailout strategies, like subintimal dissection and reentry (STAR) and subintimal plaque modification (SPM). These are invaluable when traditional techniques fail. SPM is a modification of the STAR technique in which angioplasty is performed of the occluded segment without true lumen access in the distal vessel. Available data on SPM has shown favorable outcomes with a greater than 90% success rate when the failed CTO is reattempted in 8-12 weeks after SPM has been performed. Future studies are needed to better assess its role.The retrograde dissection reentry (RDR) technique is often required to treat the most complex chronic total occlusions (CTOs). This involves a sequence of procedural steps with many potential pitfalls. Procedural planning, knowledge of the equipment, including task-specific wires and microcatheters, and the ability to systematically trouble shoot is necessary to achieve consistent success. With the combination of more complex anatomy and collateral crossing, RDR is associated with higher rates of procedural complications, which the CTO operator must be specifically trained to avoid and to manage.The hybrid approach to chronic total occlusion percutaneous coronary intervention requires facility with antegrade and retrograde strategies to achieve high success rates in a time-efficient and safe manner. Antegrade dissection and reentry is an integral component of this approach but historically has been limited by low success rates and an inability to control the site of reentry. The advent of the BridgePoint device, and multiple iterations of technique in conjunction with its use, have markedly improved success rates and procedure efficiency.The North American Hybrid Algorithm has become the standard method for percutaneous intervention for coronary chronic total occlusions. In this article, the authors discuss antegrade wire escalation as it applies to the North American Hybrid Algorithm for chronic total occlusion percutaneous coronary intervention. There is a multitude of guidewires available to operators on the market, which can quickly prove overwhelming in terms of selection, cost, and practicality. The authors simplify wires into four overall groups or families. Operators should be able to pare their toolbox down to four wires only to achieve success at antegrade wire escalation.Since the publication of the hybrid algorithm there has been rapid development of new specialty wires, microcatheters, guide extensions, and low-profile balloons to facilitate successful coronary chronic total occlusion percutaneous coronary intervention. With development of new devices, it is best to categorize them by design and intended task. This enables a safe and systematic approach to coronary chronic total occlusion percutaneous coronary intervention and avoid overlap and waste. This article serves as a guide for tool selection for the interventional cardiologist performing coronary chronic total occlusion percutaneous coronary intervention.Complex coronary artery intervention stresses the limits of both the operator's skills as well as the equipment being used for the procedure. This article is focused on avoiding, recognizing and dealing with device failure and gear entrapment during complex coronary intervention. BVD-523 The operator must understand how to avoid these complications by understanding the limits of devices and the need for adequate vessel preparation. This article focuses on giving the reader an algorithmic approach to recognizing when device failure/entrapment occurs and what specific maneuvers can be done to retrieve different devices and equipment safely.Coronary artery disease continues to advance resulting in the development of high-risk percutaneous interventions. This includes treatment of patients with multivessel disease, unprotected left main, acute myocardial infarction complicated by cardiogenic shock, and depressed left ventricular ejection fraction. As a result, mechanical circulatory support devices have evolved but require an understanding of patient hemodynamics, device mechanics, and access management. Trial data regarding device selection are limited by inclusion of cardiogenic shock patients, and observational studies are conflicted by selection bias, site familiarity with devices, and complication management; therefore, clinical judgment is required to treat high-risk patients appropriately.Dual access for chronic total occlusion percutaneous coronary intervention is considered best practice by many experts. There are 2 access sites radial and femoral. Both accesses have important advantages and disadvantages. Determining the ratio risk/benefit-efficacy/safety of each access for each patient in a specific procedure should be based on procedural and clinical variables. Given the safety benefit and the minimal procedural disadvantages, radial access should be the standard approach, especially in procedures of low complexity and in patients at high risk of vascular complications. Nonetheless, mastering both approaches is important because they are needed in multiple occasions.Coronary perforations during chronic total occlusion percutaneous coronary intervention (CTO PCI) is a most frequent major complication and the incidence is significantly higher compared with non-CTO PCI. Patients with prior history of coronary bypass have more major adverse events when perforation occurs compared with patients without prior bypass surgery. In this article, the authors discuss the unique challenges in identification and timely treatment of perforations in patients with prior bypass surgery.The most common indication for chronic total occlusion (CTO) percutaneous coronary intervention (PCI) is angina relief, which translates into improved physical function and quality of life. As the risk of the procedure is higher compared with non CTO PCI, it is important for operators to understand the current state of literature and have a detailed discussion with patients regarding risks and benefits prior to the procedure. This article discusses indications for the procedure and how to appropriately select patients for CTO PCI, in hopes of inspiring the reader to consistently offer this approach to indicated patients regardless of anatomic complexity.
