Abstract
BACKGROUND There is limited data on retrograde chronic total occlusion (CTO) percutaneous coronary intervention (PCI) via ipsilateral epicardial collaterals (IEC). AIMS To compare the clinical and angiographic characteristics, and outcomes of retrograde CTO PCI via IEC versus other collaterals in a large multicenter registry. METHODS Observational cohort study from the Prospective Global registry for the study of Chronic Total Occlusion Intervention (PROGRESS-CTO). RESULTS Of 4466 retrograde cases performed between 2012 and 2023, crossing through IEC was attempted in 191 (4.3%) cases with 50% wiring success. The most common target vessel in the IEC group was the left circumflex (50%), in comparison to other retrograde cases, where the right coronary artery was most common (70%). The Japanese CTO score was similar between the two groups (3.13 ± 1.23 vs. 3.06 ± 1.06, p = 0.456); however, the IEC group had a higher Prospective Global Registry for the Study of Chronic Total Occlusion Intervention (PROGRESS-CTO) score (1.95 ± 1.02 vs. 1.27 ± 0.92, p < 0.0001). The most used IEC guidewire was the SUOH 03 (39%), and the most frequently used microcatheter was the Caravel (43%). Dual injection was less common in IEC cases (66% vs. 89%, p < 0.0001). Technical (76% vs. 79%, p = 0.317) and procedural success rates (74% vs. 79%, p = 0.281) were not different between the two groups. However, IEC cases had a higher procedural complications rate (25.8% vs. 16.4%, p = 0.0008), including perforations (17.3% vs. 9.0%, p = 0.0001), pericardiocentesis (3.1% vs. 1.2%, p = 0.018), and dissection/thrombus of the donor vessel (3.7% vs. 1.2%, p = 0.002). CONCLUSION The use of IEC for retrograde CTO PCI was associated with similar technical and procedural success rates when compared with other retrograde cases, but higher incidence of periprocedural complications.

Prevalence of Collateral Typology in Coronary Chronic Total Occlusion and Its Impact on Percutaneous Intervention Performance. Am J Cardiol 2024; 210:153-162.

Abstract
The presence of collateral channels providing distal blood supply is a distinctive characteristic of chronic total occlusion (CTO) lesions. However, data about the distinct baseline and procedural characteristics of each collateral subset are scarce. Accordingly, we sought to explore the procedural aspects specific for each collateral typology (ipsilateral collaterals [ICs], contralateral collaterals [CCs] or mixed) in CTO-percutaneous coronary intervention (PCI). A retrospective analysis of our CTO-PCI registry was performed to investigate the prevalence, procedural characteristics, and outcomes specific for each CTO-PCI subset, defined according to the inter-arterial connection anatomy. A total of 209 cases were included. Of the included cases, 45 (22%) and 92 (44%) patients displayed solely IC or CC, respectively, whereas in 72 (34%) both IC and CC were present (mixed). The procedural success rate was high (91.1%) and comparable among the different groups, despite greater lesion complexity in the CC group. The most frequent target vessel was the left circumflex in the IC group (51% of cases) and the right coronary artery in the CC (63%) and mixed (57%) groups. Among the IC cases, 42% showed a poor collateral connection function (2% and 10% for the CC and mixed group, respectively), and 46% showed a suboptimal collateral recipient artery filling (21% and 20% for the CC and mixed group, respectively). Most of the IC cases were performed using a single access (96%). In conclusion, the success and complication rates were comparable among the collateral typology groups, irrespective of the differences in the baseline and procedural characteristics. Phenotyping CTO as hereby proposed might be helpful for targeted procedural considerations.

Retrograde Approach via Ipsilateral Septal Collateral Channel in Percutaneous Coronary Intervention for Coronary Chronic Total Occlusion: A Single-Center Experience. Clin Interv Aging 2023; 18:933-940. [PMID: 37332480 PMCID: PMC10273013 DOI: 10.2147/cia.s404818] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2023] [Accepted: 05/02/2023] [Indexed: 06/20/2023] Open
Abstract
Background The septal collateral channel (CC) is the preferred channel in retrograde percutaneous coronary intervention (PCI) for chronic total occlusion (CTO). However, reports on the utilization of the ipsilateral septal CC are limited. Objective To evaluate the feasibility and safety of the ipsilateral septal CC in retrograde CTO PCI. Methods Twenty-five patients with successful wire CC tracking via the ipsilateral septal CC in retrograde CTO PCI were retrospectively analyzed. All procedures were performed by experienced CTO operators. Procedures were divided into the left descending coronary artery (LAD)-septal-LAD group and the LAD-septal-left circumflex coronary artery (LCX) group. Procedural complications and in-hospital outcomes were ascertained. Results Both groups were similar with respect to risk factors and angiographic characteristics of the CTO, except for the collateral tortuosity (86.7% vs 20%, p=0.002). The success rate of microcatheter CC tracking was 96%. Both technical success and procedural success rates were 92%. Procedural complications were found in one case (septal perforation, 4%), which happened in the LAD-septal-LAD group (p=0.250). One postoperative adverse event (Q-wave myocardial infarction, 4%) was observed before discharge. Conclusion The retrograde approach via the ipsilateral septal CC was feasible, with high success rates and acceptable complications, in the hands of experienced operators.

Retrograde Chronic Total Occlusion Percutaneous Coronary Interventions: Predictors of Procedural Success From the ERCTO Registry. JACC Cardiovasc Interv 2022; 15:834-842. [PMID: 35450685 DOI: 10.1016/j.jcin.2022.02.013] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/22/2021] [Revised: 01/31/2022] [Accepted: 02/08/2022] [Indexed: 01/07/2023]
Abstract
OBJECTIVES The aim of this study was to identify independent predictors of procedural success after retrograde chronic total occlusion (CTO) percutaneous coronary intervention (PCI). BACKGROUND Retrograde CTO PCI is an established technique, but predictors of success remain poorly understood. METHODS A multivariable logistic regression model was used to analyze potentially important demographic, clinical, anatomical, and technical aspects of retrograde CTO PCI cases uploaded to the multicenter European CTO (ERCTO) Club Registry. RESULTS In calendar years 2018 and 2019, 2,364 retrograde CTO PCI cases constituted the primary analysis cohort. A primary retrograde strategy was used in 1,953 cases (82.6%), and an initial antegrade approach was converted to retrograde in 411 cases (17.4%). Procedural success was achieved in 1,820 cases (77.0%) and was more likely to occur after a primary retrograde attempt versus conversion from an initial antegrade approach (80.9% vs 58.4%; P < 0.0001). After multivariable analysis, an absence of lesion calcification (OR: 1.86; 95% CI: 1.37-2.51; P < 0.0001), a higher degree of distal vessel opacification (OR: 2.47; 95% CI: 1.72-3.55; P < 0.0001), little or no proximal target vessel tortuosity (OR: 1.84; 95% CI: 1.28-2.64; P = 0.001), Werner collateral connection CC1 (OR: 4.87; 95% CI: 2.90-8.19; P < 0.0001) or CC2 (OR: 5.33; 95% CI: 3.02-9.42; P < 0.0001), and the top tertile of operator volume (>120 cases over 2 years) (OR: 1.88; 95% CI: 1.26-2.79; P = 0.002) were associated with the greatest chance of achieving angiographic success. CONCLUSIONS Less calcification with good distal vessel opacification, little or absent proximal vessel tortuosity, and visible collateral connections, along with high-volume operator status, were all independently predictive of angiographically successful retrograde CTO PCI.

Abstract
Objectives To analyse the feasibility, safety and procedural outcomes of percutaneous coronary intervention (PCI) for chronic total occlusions (CTO) through retrograde approach using single catheter. Methods Our study was a retrospective observational study that enrolled patients who underwent retrograde CTO PCI using a single catheter between June 2016 and February 2020. Clinical success was defined as successful completion of CTO PCI without associated in-hospital major clinical complications like death, myocardial infarction, stroke or urgent revascularisation. Technical success was defined as successful completion of CTO PCI using single catheter and minimum diameter stenosis of <30% with thrombolysis in myocardial infarction (TIMI) flow grade 3, without significant side branch occlusion, flow-limiting dissection, distal embolization, or angiographic thrombus. Results Totally 102 patients underwent retrograde CTO PCI during the study period. Out of which, 15 cases were attempted using single catheter. Mean age of the population was 59.1 ± 8.9 years (males: 86.7%) and the left ventricular ejection fraction (LVEF) was (61% ± 9.1%). Mean number of diseased arteries was 2.1 ± 0.7, length of the CTO was 25.5 ± 7.4 mm and J-CTO score was 2.3 ± 0.7. We achieved a technical success rate of 73.3% using single catheter, and the overall clinical success (Including single catheter and ping pong) was obtained in 86.7% cases. One patient (6.7%) developed cardiac tamponade and none of study population required dialysis for contrast induced acute kidney injury (CI-AKI) Conclusions Retrograde CTO PCI using single catheter is a technically challenging procedure when compared with other CTO PCI. Our study demonstrated acceptable outcomes which is comparable to other antegrade and retrograde CTO PCI registries.

Abstract
Coronary chronic total occlusion (CTO) has gained increasing clinical attention as the most advanced form of coronary artery disease. Prior studies already indicated a clear association of CTO with adverse clinical outcomes, especially in patients with acute myocardial infarction (AMI) and concomitant CTO of the non-infarct-related coronary artery (non-IRA). Nevertheless, the prognostic impact of percutaneous coronary intervention (PCI) of CTO in the acute setting during AMI is still controversial. Due to the complexity of the CTO lesion, CTO-PCI leads to an increased risk of complications compared to non-occlusive coronary lesions. Therefore, this review outlines the prognostic impact of CTO-PCI in patients with AMI. In addition, the prognostic impact of periprocedural myocardial infarction caused by CTO-PCI will be discussed.

Abstract
A careful angiographic assessment of a chronic total occlusion (CTO) is essential for optimal procedural planning. In the classic hybrid approach, the insertion of two guiding catheters at the beginning of the intervention is recommended. This is fundamental to perform simultaneous double injection, to achieve complete visualization of the coronary circulation and to choose the best starting strategy between antegrade wire escalation (AWE), antegrade dissection and re-entry (ADR) and the retrograde techniques (retrograde wire escalation [RWE] and retrograde dissection and re-entry [RDR]). In the hybrid algorithm the set-up is the same, regardless of the chosen first strategy, and therefore routinely uses double access. Because revascularizations of CTOs commonly require large bore catheters (7-8 French) to ensure high back-up support, the femoral arterial access is preferred by most of the operators. However, the use of a double access, large introducer sheaths and femoral approach are associated with a greater risk of access-related complications and even the occurrence of major adverse cardiovascular events. We have previously proposed an algorithm, called "minimalistic hybrid approach," which aims to limit the routine use of dual injection, and to favor the use of trans-radial access and smaller (6-7 French) guiding catheters. In this algorithm the chosen starting strategy depends on the complexity of the lesion assessed by J-CTO Score and on the presence of favorable contralateral interventional collateral circulation. However, this novel algorithm proved to have some limitations, such as the non-specific evaluation of CTOs with ipsilateral collateral circulation and the too arbitrary choice of the starting strategy based on a J-CTO Score cut-off. These considerations led to the development of an "updated" minimalistic hybrid approach algorithm that considers the type of collaterals (ipsilateral or contralateral) and the a-priori choice of the hybrid technique, with the highest chance of success in that specific CTO lesion (independently from the J-CTO Score). One important aspect that makes this algorithm unique is its "dynamicity:" not only for the technique to be used, as in the classic hybrid algorithm (shifting between AWE, ADR, RWE and RDR), but also for the set-up, with access site and French size to be adapted during the PCI to the technique adopted. We believe that this novel approach could further improve the safety of CTO-PCI without losing its current efficacy.

Abstract
OPINION STATEMENT Successful percutaneous coronary intervention (PCI) of chronic total occlusions (CTOs) has been associated with significant clinical benefits, but remains technically demanding. Failure to cross the CTO with a guidewire is the most common cause of CTO PCI failure. CTO crossing can be achieved in the antegrade or retrograde direction and can be accomplished by maintaining true lumen position throughout or via subintimal dissection/reentry techniques. A procedural plan should be created prior to the procedure through careful angiographic review of four key parameters: (a) morphology of the proximal occlusion cap; (b) length of the occlusion; (c) quality of the distal vessel and presence of bifurcation at the distal cap; and (d) suitability of collateral circulation for retrograde crossing. Dual coronary injection is recommended in all cases with contralateral collaterals for detailed characterization of the lesion. If one approach fails to progress, a quick transition to the next approach is encouraged to maximize efficacy and efficiency. Procedural complications, including vessel perforation, may occur more frequently in CTO as compared with non-CTO PCI; hence, availability of necessary equipment and expertise in treating such complications are essential.

Abstract
Chronic occlusion of coronary arteries also known as chronic total occlusions (CTO) are found in approximately 20 % of patients undergoing percutaneous coronary interventions (PCI) and in approximately 50 % of patients after coronary artery bypass grafts (CABG). As a result of technical advancements in retrograde recanalization techniques specialized centers can now achieve success rates of over 85 %, regardless of the CTO anatomy. Given the complexity of retrograde CTO techniques, a consensus paper issued by the Euro CTO Club requires interventional cardiologists to have sufficient experience in antegrade approaches (>300 antegrade CTO cases and >50 per year) with an additional training program (25 retrograde cases each as first and second operating surgeon) before becoming a qualified independent retrograde surgeon. The increased investment in time and technical resources can only be justified if the patient has a clear clinical benefit. This technical advancement and the progressively clearer evidence that complete revascularization can be achieved in patients with multivessel coronary artery disease have attracted growing interest in recent years from interventional cardiologists in the recanalization of CTO.
