Treatment of coronary chronic total occlusions represents one of the major challenges in the field of interventional cardiology. This is due to the complexity of these procedures and to the relatively higher risk of complications. In recent years, the development of innovative techniques and the evolution of materials have produced significant progress in this field. Better procedural outcomes have been achieved, with fewer complications. This article highlights the most recent scientific evidence and techniques, with the intention to guide interventional cardiologists in optimal patient selection and procedure choice.

Procedural Success

Chronic total occlusions (CTOs) are common in patients with ischaemic heart disease. In many countries, patients with CTOs are underserved by percutaneous coronary intervention (PCI). One of the barriers to CTO PCI is the technical challenges of these procedures. Improvements in technique and dedicated devices for CTO PCI, combined with advances in procedural strategy, have resulted in a dramatic increase in procedural success and outcomes. Antegrade wiring (AW) is the preferred initial strategy in short CTOs, where the proximal cap and course of the vessel is understood. For many longer, more complex occlusions, AW has a low probability of success. Dissection and re-entry techniques allow longer CTOs and those with ambiguous anatomy to be crossed safely and efficiently, and CTO operators must also be familiar with these strategies. The CrossBoss and Stingray system is currently the primary targeted re-entry device used during antegrade dissection and re-entry (ADR), and there continues to be an evolution in its use to increase procedural efficiency. In contrast to older ADR techniques, targeted re-entry allows preservation of important side-branches, and there is no difference in outcomes compared to intraplaque stenting.

Safety Benefit

Percutaneous revascularisation of a coronary chronic total occlusion (CTO) remains one of the technical frontiers of interventional cardiology. CTOs are common, and yet intervention is only attempted in 10 % of cases. CTO procedures are perceived to be technically challenging, lengthy, associated with significant risk and have only limited data to support the practise. Recent technical advances have dramatically increased the success rate, shortened procedural time and improved clinical outcomes. The aim of this article is to critically examine the data that supports CTO intervention, including specifically an appraisal of procedural safety, benefit and overall cost effectiveness.

Set Up

Chronic total occlusion (CTO) of a coronary artery remains one of the most challenging scenarios in cinical practice. There is much debate about whether opening a CTO is clinically indicated and the procedures are often considered too risky. As a result many patients with a clinical indication for percutaneous coronary intervention (the presence of angina despite medical therapy, with proven ischaemia and viability) are not offered treatment. This chapter will aim to demystify the procedure by explaining how pathophysiological features can help understand the anatomy and how cath lab set-up can increase procedural efficiency, safety, and overall success rates. There are four methods by which a CTO can be opened and we will describe these methods and the anatomically salient features to help select the most appropriate method with which to start.

Background- Although a total coronary occlusion is identified approximately in one third of the diagnostic cardiac catheterizations, still an attempted revascularization of total occlusion accounts for less than 8% of all percutaneous coronary interventions (PCI). Percutaneous Coronary Intervention (PCI) of chronic total occlusion (CTO) is one of the major challenges in interventional cardiology. It is now an well-accepted revascularization procedure.  Methods: It was a prospective observational study conducted in National Institute of Cardiovascular Diseases, Dhaka, from July 2004 to June 2005. 50 consecutive patients with chronic total occlusion undergoing PCI were included in the study. Patients were observed during procedure and during the hospital stay. Result: The mean age of the patients was 46.7 ± 9.3 and 48.0% were in the age range of 45-54 years. 24 patients had post MI angina, 20 patients had chronic stable angina and 6 patients had unstable angina. Technical success was in 98% cases and procedural success was in 94% cases. One patient developed vessel perforation and was treated by prolonged balloon inflation. There was no death or STEMI and only 2 patients developed NSTEMI. Conclusion: In our study with the use of available facilities PCI in CTOs was possible with a high success rate. But dealing of more complicated lesion will require more improved technology and hardware. A study with larger number of patients and longer duration of follow up to determine the efficacy of the procedure in improving morbidity and mortality is needed.

Chronic total occlusion recanalization still represents the final frontier in percutaneous coronary intervention. Retrograde recanalization is one of the greatest amendments of this technique. At present, it has become an integral complement to the traditional antegrade approach. Despite being most frequently used in complex patients, it has the highest success rate with the lowest incidence of complications. Since its inception, significant iterations have occurred that made this technique safer, faster, and even more successful.
