AbstractChronic total occlusion (CTO) is a common challenge accounting for 10% of coronary lesions found on coronary angiography. Patients are frequently referred for bypass surgery because percutaneous coronary intervention is challenging in this subset. Recent advances in the hardware as well as the technical expertise and an algorithm approach have improved the success to more than 90%.Antegrade approach is the cornerstone for managing CTO and has two distinct strategies: antegrade wire escalation, and antegrade dissection and reentry strategy. Step-wise approach to perform these procedures and the use of adjunct imaging are discussed.

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.

The retrograde approach has increased the success rate of chronic total occlusion percutaneous coronary intervention but has also been associated with a higher risk of complications. The retrograde approach is usually performed in complex lesions, in which the antegrade approach is not feasible or has failed previously. Using a systematic 10-step approach can maximize the likelihood of success and minimize the risks of retrograde chronic total occlusion interventions.

Chronic total occlusion recanalization still represents the final frontier in percutaneous coronary intervention. Successful revascularization is associated with improved long-term survival, reduced symptoms, improved left ventricular function and reduced need for coronary bypass surgery. Retrograde chronic total occlusion recanalization has recently become an essential complement to the classic antegrade approach. Retrograde approach through the collateral channel has been recently proposed and has the potential to improve the success rate of percutaneous coronary intervention (PCI) in chronic total occlusion (CTO) lession of the coronary arteries. We report several cases of successful CTO recanalization procedure using retrograde approach in Soetomo Hospital.

Background: Lesion characteristics of chronic total occlusion (CTO) are predictors of percutaneous coronary intervention (PCI) success. A prediction score consist of these predictors can help CTO-PCI operators. Various prediction score had been established but none had been established in Indonesian population. Methods: This observational cohort study was performed in patients underwent native vessel CTO-PCI in Dr.Kariadi Hospital during 2018. Target vessels, ostial lesion, blunt stump, calcification, long lesion, bending, side branch, bridging collateral, and retrograde collateral were angiographic variables proposed to be predictors of CTO-PCI success. All of the variables were quantitatively assessed by two observers. Bivariate and multivariate analysis used to identify independent predictors of CTO-PCI success and to establish a scoring model. Results: A total 200 patients underwent CTO-PCI procedures were included to this study. All of the procedures used antegrade approach. The prediction score established as follows: bending (1 point), calcification (2 point), blunt stump (3 point), long lesion (1 point), and poor retrograde collateral filling (2 point). Total score ranged from 0 to 9 with decreased probability of success from 92.3% to 0.5%. Score value ? 3 categorized as difficult lesion with higher risk to failure compared to score value <3 (OR 15.4; p<0.001). The score model had good calibration and discrimination in predict CTO-PCI success (AUC 0.88; p<0.001). Conclusion: Bending, calcification, blunt stump, long lesion, and poor retrograde collateral were predictors of CTO-PCI success. The score consist of these variables could predict antegrade CTO-PCI success. Keywords: chronic total occlusion; percutaneous coronary intervention; success; prediction score.

AbstractTotal 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.A total of 188 patients were studied. Mean ± SD age was 59 ± 9 years. Failure rate was 33%. In a stepwise multivariate regression analysis, bridging collaterals (OR = 6.7, CI = 1.97–23.17, score = 2), absence of stump (OR = 5.8, CI = 1.95–17.9, score = 2), presence of calcification (OR = 3.21, CI = 1.46–7.07, score = 1), presence of bending (OR = 2.8, CI = 1.28–6.10, score = 1), presence of near side branch (OR = 2.7, CI = 1.08–6.57, score = 1), and absence of retrograde filling (OR = 2.5, CI = 1.03–6.17, score = 1) were independent predictors of PCI failure. A score of 7 or more was associated with 100% failure rate whereas a score of 2 or less was associated with over 80% success rate.Most factors associated with failure of CTO-PCI are related to lesion characteristics. A new risk score (range 0–8) is developed to predict CTO-PCI success or failure rate during antegrade approach as a guide before attempting PCI of CTO lesions.

Chronic total occlusion recanalization still represents the last frontier in percutaneous coronary intervention. Retrograde recanalization is one of the most significant amendments of the technique, and has recently become an essential complement to the classical antegrade approach. It has a high success rate with a low complication profile, despite frequent utilization in the most complex patients. Since its initial description, important iterations have occurred and made the technique safer, faster and more successful.
