“…Since the publication of these guidelines, CTO PCI in the USA (as well as around the world) has undergone drastic improvements with success rates consistently above 90% and major complication rates around 2% reported in several expert CTO sites. 62,63 In Canada, the current guidelines are vague for the management of patients with CTOs. In the latest Canadian Cardiovascular Society Guidelines for the Diagnosis and Management of Stable Ischemic Heart Disease published in 2014, there is not even a single mention about CTOs.…”

Coronary chronic total occlusions (CTOs) are commonly encountered in patients undergoing coronary angiography. Several observational studies have demonstrated that successful CTO revascularization is associated with better cardiovascular outcomes and enhanced quality of life (QOL). However, in the absence of randomized trials, its prognostic benefit for patients remains debated. Over the past decade, the interest of the interventional community in CTO percutaneous coronary intervention (PCI) has exponentially grown due to important developments in dedicated equipment and techniques, resulting in high success and low complication rates. Both European and American guidelines have assigned a class IIa (level of evidence B) recommendation for CTO PCI. In the current review, we focus on the impact of CTO revascularization on clinical outcomes and QOL and on appropriate patient selection, and we provide a critical assessment of the current guidelines and recommendations on CTO PCI.

“…Two general collateral circulation traverse approaches exist. The original Japanese method involves selecting a collateral vessel with high probability of connection, reliance upon sequential distal microcatheter tip injections for visualization and isolation of the connecting collateral vessel, and attempted traverse with a dedicated wire [5,12,[21][22][23] . The Western method, also known as the "septal sur ng technique" (SST, rst described by Sianos, forgoes distal tip injections and employs wire probing via trial and error in seeking a path of lowest resistance in the septal collateral channels [21] .…”

Background Retrograde approach technique has been challenging in percutaneous coronary interventional treatment of chronic total occlusion (CTO) coronary disease. The present study endeavors to determine a novel Chinese scoring system for predicting successful collateral channels traverse via retrograde approach. Methods The demographic characteristics and angiographic characteristics of 309 CTO patient were analyzed by univariate and multivariate analysisfor selecting potential predictors. And the nomogram was used to establish the scoring system. Then it was evaluated by the internal and external validation. Results The predictors of Age, Connections between collateral channels and recipient vessels, and Channel Tortuosity (ACT) were identified with multivariate analysis and employed to the ACT score system. With acceptable calibrations, the AUC of the scoring system and the external validation were 0.826 and 0.816 respectively. Based on score, the predictors were divided into three risk categories and it showed a consistent prediction power in the validation cohort. Conclusions The novel Chinese ACT score is a reliable tool for predicting successful retrograde collateral traverse.

“…After predilatation drug-eluting stents (DES) were implanted. The J-CTO Score was calculated for all of the CTO lesions [ 8 ]. In-hospital major adverse cardiovascular events were defined as death, emergency repeat revascularization at the previously opened artery, emergency coronary artery bypass grafting (CABG), myocardial infarction or stroke.…”

IntroductionIn past studies, it has been questioned whether success of recanalization of chronic total occlusion (CTO) depends on the location of the occlusion – the circumflex artery (Cx) was considered as the most difficult to open.AimTo determine whether the effectiveness of recanalization of CTO depends on the location of the obstruction.Material and methodsFrom January 2011 to January 2016, a single operator dedicated to chronic total occlusions performed in our center 357 procedures on 337 patients.ResultsAmong 337 patients included in the study, 83.4% were male. Mean age was 62.8 ±9.3 years. Most of the patients had hypertension (86.4%) and hyperlipidemia (99.4%), and 28.8% of them had diabetes. The most frequently opened artery was the right coronary artery (RCA; 52.4%), followed by the left anterior descending artery (LAD; 29.4%), and last the Cx (18.2%). The mean J-CTO score was comparable between the three groups. The success rate of recanalization of CTO was similar for all arteries: 84.5% in the RCA, 81.9% in the LAD and 89.2% in the Cx (overall p = 0.437). Neither procedural complications nor adverse events depended on the location of the CTO.ConclusionsOur study shows the same efficacy of CTO procedures of all epicardial arteries. We did not observe that effectiveness of recanalization of CTO depends on the location of the obstruction.
