[PMID: 37676010 DOI: 10.1002/ccd.30830] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/23/2023] [Revised: 08/21/2023] [Accepted: 08/27/2023] [Indexed: 09/08/2023]
Abstract
BACKGROUND There is limited data on the use of the balloon-assisted subintimal entry (BASE) technique in chronic total occlusion (CTO) percutaneous coronary intervention (PCI). METHODS We analyzed the baseline clinical and angiographic characteristics and outcomes of 155 CTO PCIs that utilized the BASE technique at 31 US and non-US centers between 2016 and 2023. RESULTS The BASE technique was used in 155 (7.9%) of 1968 antegrade dissection and re-entry (ADR) cases performed during the study period. The mean age was 66 ± 10 years, 88.9% of the patients were men, and the prevalence of diabetes (44.6%), hypertension (90.5%), and dyslipidemia (88.7%) was high. Compared with 1813 ADR cases that did not use BASE, the target vessel of the BASE cases was more commonly the RCA and less commonly the LAD. Lesions requiring BASE had longer occlusion length (42 ± 23 vs. 37 ± 23 mm, p = 0.011), higher Japanese CTO (J-CTO) (3.4 ± 1.0 vs. 3.0 ± 1.1, p < 0.001) and PROGRESS-CTO (Prospective Global Registry for the Study of Chronic Total Occlusion Intervention chronic total occlusion) (1.8 ± 1.0 vs. 1.5 ± 1.0, p = 0.008) scores, and were more likely to have proximal cap ambiguity, side branch at the proximal cap, blunt/no stump, moderate to severe calcification, and proximal tortuosity. Technical (71.6% vs. 75.5%, p = 0.334) and procedural success (71.6% vs. 72.8%, p = 0.821), as well as major adverse cardiac events (MACE) (1.3% vs. 4.1%, p = 0.124), were similar in ADR cases that used BASE and those that did not. CONCLUSIONS The BASE technique is used in CTOs with longer occlusion length, higher J-CTO score, and more complex angiographic characteristics, and is associated with moderate success but also low MACE.

Abstract
Artificial intelligence, computational simulations, and extended reality, among other 21st century computational technologies, are changing the health care system. To collectively highlight the most recent advances and benefits of artificial intelligence, computational simulations, and extended reality in cardiovascular therapies, we coined the abbreviation AISER. The review particularly focuses on the following applications of AISER: 1) preprocedural planning and clinical decision making; 2) virtual clinical trials, and cardiovascular device research, development, and regulatory approval; and 3) education and training of interventional health care professionals and medical technology innovators. We also discuss the obstacles and constraints associated with the application of AISER technologies, as well as the proposed solutions. Interventional health care professionals, computer scientists, biomedical engineers, experts in bioinformatics and visualization, the device industry, ethics committees, and regulatory agencies are expected to streamline the use of AISER technologies in cardiovascular interventions and medicine in general.

Abstract
The outcomes of chronic total occlusion (CTO) percutaneous coronary interventions (PCIs) in patients with previous coronary artery bypass graft (CABG) surgery have received limited study. We examined the baseline characteristics and outcomes of CTO PCIs performed at 47 United States and non-United States centers between 2012 and 2023. Of the 12,164 patients who underwent CTO PCI during the study period, 3,475 (29%) had previous CABG. Previous CABG patients were older, more likely to be men, and had more comorbidities and lower left ventricular ejection fraction and estimated glomerular filtration rate. Their CTOs were more likely to have moderate/severe calcification and proximal tortuosity, proximal cap ambiguity, longer lesion length, and higher Japanese CTO scores. The first and final successful crossing strategy was more likely to be retrograde. Previous CABG patients had lower technical (82.1% vs 88.2%, p <0.001) and procedural (80.8% vs 86.8%, p <0.001) success, higher in-hospital mortality (0.8% vs 0.3%, p <0.001), acute myocardial infarction (0.9% vs 0.5%, p = 0.007) and perforation (7.0% vs 4.2%, p <0.001) but lower incidence of pericardial tamponade and pericardiocentesis (0.1% vs 1.3%, p <0.001). At 2-year follow-up, the incidence of major adverse cardiac events, repeat PCI and acute coronary syndrome was significantly higher in previous CABG patients, whereas all-cause mortality was similar. In conclusion, patients with previous CABG who underwent CTO PCI had more complex clinical and angiographic characteristics and lower success rate, higher perioperative mortality, and myocardial infarction but lower tamponade, and higher incidence of major adverse cardiac events with similar all-cause mortality during follow-up.

Abstract
Successful crossing of the target coronary lesion with a guidewire is an essential step in percutaneous coronary intervention. Guidewire advancement can be challenging, especially in tortuous, severely stenosed, and heavily calcified lesions. The use of a microcatheter significantly improves the guidewire steerability and penetration force, but it requires specific training and is associated with increased procedural costs. We present the first in vivo experience with a new type of rapid exchange microcatheter (Micro Rx, Interventional Medical Device Solutions), describe bench testing of combinations of guidewires and microcatheters, and suggest potential applications.

Abstract
BACKGROUND Donor vessel injury is a potentially life-threatening complication of chronic total occlusion (CTO) percutaneous coronary intervention (PCI). AIMS Our goal was to examine the incidence, mechanisms, treatment, and outcomes of patients with donor vessel injury in a large multicenter CTO PCI registry. METHODS We analyzed the baseline clinical and angiographic characteristics, and procedural outcomes of 12,349 CTO PCIs performed between 2012 and 2022 at 44 centers. RESULTS The incidence of donor vessel injury was 0.35% (n = 43). The baseline clinical characteristics of patients with and without donor vessel injury were similar. Cases complicated by donor vessel injury were more complex with higher Japanese CTO score (2.9 ± 1.1 vs. 2.4 ± 1.3; p = 0.004) and lower procedural success rate (69.8% vs. 85.2%; p = 0.004). The retrograde approach was used more commonly in donor vessel injury cases (68.9% vs. 30.9%; p < 0.001). Most (53.5%) donor vessel injuries were guide catheter-induced, whereas 20.9% were due to donor vessel thrombosis. Of the 43 patients with donor vessel injury, 36 (83.7%) were treated with stenting and seven (16.3%) received a left ventricular assist device. The incidence of major adverse cardiovascular events (MACEs) was significantly higher in cases with donor vessel injury (23.3% vs. 2.0%; p < 0.001). Of the 43 patients with donor vessel injury, five patients (11.6%) experienced acute myocardial infarction and four patients (9.3%) died. CONCLUSIONS Donor vessel injury, occurred in 0.35% of CTO PCIs performed by experienced operators, was mainly due to guide catheter-induced dissection or thrombosis and was associated with lower procedural success and higher MACE.

The role of intravascular imaging in chronic total occlusion percutaneous coronary intervention. Front Cardiovasc Med 2023; 10:1199067.

Abstract
Chronic total occlusions (CTOs) represent the most complex subset of coronary artery disease and therefore careful planning of CTO percutaneous coronary recanalization (PCI) strategy is of paramount importance aiming to achieve procedural success, and improve patient's safety and post CTO PCI outcomes. Intravascular imaging has an essential role in facilitating CTO PCΙ. First, intravascular ultrasound (IVUS), due to its higher penetration depth compared to optical coherence tomography (OCT), and the additional capacity of real-time imaging without need for contrast injection is considered the preferred imaging modality for CTO PCI. Secondly, IVUS can be used to resolve proximal cap ambiguity, facilitate wire re-entry when dissection and re-entry strategies are applied and most importantly to guide stent deployment and optimization post implantation. The role of OCT during CTO PCI is currently limited to stent sizing and optimization, however, due to its high spatial resolution, OCT is ideal for detecting stent edge dissections and strut malapposition. In this review, we describe the use of intravascular imaging for lesion crossing, plaque characterization and wire tracking, extra- or intra-plaque, and stent sizing and optimization during CTO PCI and summarize the findings of the major studies in this field.

Abstract
Knowledge in the field of bifurcation lesions and chronic total occlusions (CTOs) has progressively improved over the past 20 years. Therefore, the European Bifurcation Club and the EuroCTO Club have decided to write a joint consensus statement to share general knowledge and practical approaches in this complex field. When percutaneously treating CTOs, bifurcation lesions with relevant side branches (SBs) are found in approximately one-third of cases (35% at the proximal cap, 38% at the distal cap, and 27% within the CTO body). Occlusion of a relevant SB is not rare and has been shown to be associated with procedural complications and adverse outcomes. Simple bifurcation rules are very useful to prevent SB occlusion, and provisional SB stenting is the recommended approach in the majority of cases: protect the SB as soon as possible by wiring it, respect the fractal anatomy of the bifurcation by using the 3-diameter rule, and avoid using dissection and re-entry techniques. A systematic 2-stent approach can be used if needed or sometimes to connect both branches of the bifurcation. The retrograde approach can be very useful to save a relevant SB, especially in the case of a bifurcation at the distal cap or within the CTO body. Intravascular ultrasound is also a very important tool to address the difficulties with bifurcations at the proximal or distal cap and sometimes also within the CTO segment. Double-lumen microcatheters and angulated microcatheters are crucial tools to resolve access difficulties to the SB or the main branch.

Abstract
Coronary artery disease (CAD) is multifactorial and strongly affected by genetic, epigenetic and environmental factors. Several studies have reported development of concomitant CAD in identical twins. We report a case in which a pair of Caucasian male monozygotic twins presented almost concomitantly with acute coronary syndrome (ACS) and had concordant coronary anatomy and identical site of occlusion. We performed a systematic literature review of PubMed, Web Of Science and Scopus databases from inception until 28 February 2023 of case reports/case series reporting the concomitant development of CAD in monozygotic twins. We found 25 eligible case reports with a total of 31 monozygotic twin pairs (including the case from our center) suffering from CAD and presenting (most of them simultaneously) with ACS (mean age of presentation: 45 ± 12 years, males: 81%). Coronary angiograms demonstrated lesion and anatomy concordance in 77% and 79% of the twin pairs, respectively. Screening for disease-related genetic mutations was performed in six twin pairs leading to the identification of five CAD-related genetic polymorphisms. This is the first systematic literature review of studies reporting identical twin pairs suffering from CAD. In summary, there is high concordance of coronary anatomy and clinical presentation between monozygotic twins. Future monozygotic twin studies-unbiased by age effects-can provide insights into CAD heritability being able to disentangle the traditional dyad of genetic and environmental factors and investigate the within-pair epigenetic drift.

Abstract
Estimating the likelihood of urgent mechanical circulatory support (MCS) can facilitate procedural planning and clinical decision-making in chronic total occlusion (CTO) percutaneous coronary intervention (PCI). We analyzed 2,784 CTO PCIs performed between 2012 and 2021 at 12 centers. The variable importance was estimated by a bootstrap applying a random forest algorithm to a propensity-matched sample (a ratio of 1:5 matching cases with controls on center). The identified variables were used to predict the risk of urgent MCS. The performance of the risk model was assessed in-sample and on 2,411 out-of-sample procedures that did not require urgent MCS. Urgent MCS was used in 62 (2.2%) of cases. Patients who required urgent MCS were older (70 [63 to 77] vs 66 [58 to 73] years, p = 0.003) compared with those who did not require urgent MCS. Technical (68% vs 87%, p <0.001) and procedural success (40% vs 85%, p <0.001) was lower in the urgent MCS group compared with cases that did not require urgent MCS. The risk model for urgent MCS use included retrograde crossing strategy, left ventricular ejection fraction, and lesion length. The resulting model demonstrated good calibration and discriminatory capacity with the area under the curve (95% confidence interval) of 0.79 (0.73 to 0.86) and specificity and sensitivity of 86% and 52%, respectively. In the out-of-sample set, the specificity of the model was 87%. The Prospective Global Registry for the Study of Chronic Total Occlusion Intervention CTO MCS score can help estimate the risk of urgent MCS use during CTO PCI.

Abstract
BACKGROUND There is limited information on the impact of the target vessel on the procedural techniques and outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI). METHODS We analyzed the baseline clinical and angiographic characteristics and procedural outcomes of 11,580 CTO PCIs performed between 2012 and 2022 at 44 centers. RESULTS The most common CTO target vessel was the right coronary artery (RCA) (53.1%) followed by the left anterior descending artery (LAD) (26.0%) and the left circumflex artery (LCX) (19.8%). RCA CTOs were longer and more complex, with a higher Japanese CTO score compared with LAD or LCX CTOs. Technical success was higher among LAD (88.8%) lesions when compared with RCA (85.7%) or LCX (85.8%) lesions (P less than .001). The incidence of major adverse cardiovascular events (MACE) was overall 1.9% (n = 220) and was similar among target vessels (P=.916). There was a tendency toward more frequent utilization of the retrograde approach for more proximal occlusions in all 3 target vessels. When compared with all other RCA lesions combined, distal RCA lesions had higher technical success (87.7% vs 85.3%; P=.048). Technical success was similar between various locations of LAD CTOs (P=.704). First/second/third obtuse marginal branch had lower technical success when compared with all other LCX lesion locations (82.7% vs 86.8%; P=.014). There was no association between MACE and CTO location in all 3 target vessels. CONCLUSIONS LAD CTO PCIs had higher technical and procedural success rates among target vessels. The incidence of MACE was similar among target vessels and among various locations within the target vessel.

Abstract
Percutaneous coronary intervention (PCI) on heavily calcified lesions has been associated with more complications.1 Intravascular lithotripsy (IVL) was recently approved for treating de novo calcified coronary lesions based on excellent safety and efficacy on several studies, but there are limited "real world" outcomes. We conducted a comprehensive search of the MAUDE database between February 12, 2021, and February 28, 2023 using the manufacturer and brand name tabs with the keywords "Shockwave Medical" and "Shockwave," respectively. Given that a single IVL catheter can fail or cause multiple adverse events through different mechanisms, we considered all possible outcomes. The MAUDE database is freely accessible and de-identified, obviating the need for institutional review board approval.

Abstract
Percutaneous coronary intervention of heavily calcified coronary vessels can be challenging due to difficult equipment delivery and suboptimal stent expansion, leading to worse clinical outcomes. Supportive guidewires are designed to facilitate equipment delivery. We present two cases of heavily calcified and tortuous coronary lesions in which use of support guidewires hindered balloon and stent delivery, possibly by increasing friction between equipment and the wall of the coronary vessel. Equipment delivery was achieved using less supportive workhorse guidewires.

Despite significant progress, chronic total occlusion (CTO) percutaneous coronary interventions (PCI) are often challenging and carry increased risk of complications. We present a highly complex CTO PCI case that was successfully completed despite numerous complications (perforation, donor vessel closure, stent loss, guide extension tip fracture, access site bleeding and cardiac arrest) to highlight the importance of appropriate patient selection, pre-procedural planning, comprehensive patient-centered risk/benefit discussion, and prompt recognition and treatment of intra-procedural complications.

Abstract
The outcomes of chronic total occlusion percutaneous coronary intervention have considerably improved during the last decade with continued emphasis on improving procedural safety. Vascular access site bleeding remains one of the most frequent complications. Several procedural strategies have been implemented to reduce the rate of vascular access site complications. This state-of-the-art review summarizes and describes the current evidence on optimal vascular access strategies for chronic total occlusion percutaneous coronary intervention.

Abstract
BACKGROUND We examined the effect of atrial fibrillation on the outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI). METHODS We examined the baseline characteristics and procedural outcomes of 9,166 CTO PCIs performed at 39 US and non-US centers between 2012 and 2023. RESULTS Atrial fibrillation was present in 1122 (12%) patients. These patients were older and had a higher incidence of comorbidities, such as hypertension, dyslipidemia, heart failure, cerebrovascular disease, and peripheral arterial disease, lower left ventricular ejection fraction, and lower eGFR. Their CTOs were more likely to have moderate to severe calcification and longer lesion length. They also had higher mean J-CTO and PROGRESS-CTO complications (Acute MI, MACE, Mortality, Perforation, and Pericardiocentesis) scores. Patients with atrial fibrillation had higher prevalence of uncrossable and undilatable CTO lesions and required longer procedure (107 vs 119 min; P less than .001) and fluoroscopy (40 vs 43 min; P=.005) time. Technical success and MACE, including procedural/in-hospital bleeding, were similar in patients with and without atrial fibrillation. Although the crude incidence of MACE on follow-up (median 61 days) was significantly higher in patients with atrial fibrillation, the latter was not independently associated with adverse events on Cox proportional hazards analysis. CONCLUSIONS Patients with atrial fibrillation undergoing CTO PCI are older, have more comorbidities, higher lesion complexity, and longer procedure time, but similar technical success and in-hospital MACE. They have higher MACE and mortality during follow-up, but the difference is not significant after adjusting for potential confounding variables.

The importance of the "safety coronary guidewire" in the donor vessel during Chronic total occlusion percutaneous coronary intervention. CARDIOVASCULAR REVASCULARIZATION MEDICINE 2023; 53S:S292-S295. [PMID: 36737384 DOI: 10.1016/j.carrev.2023.01.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2022] [Revised: 01/05/2023] [Accepted: 01/09/2023] [Indexed: 01/13/2023]
Abstract
Donor vessel injury is a well-known complication of chronic total occlusion (CTO) percutaneous coronary intervention (PCI). Due to significant amount of myocardium at risk, donor vessel injury may lead to rapid hemodynamic collapse. In this setting, prompt restoration of blood flow into the donor artery is of paramount importance. Advancement of a safety coronary workhorse guidewire in the donor vessel prior to attempting CTO PCI is a simple maneuver that provides access to the donor artery for rapid coronary intervention and restoration of blood flow, in the event of donor vessel injury. We describe two cases of CTO PCI that illustrate the value of the safety coronary guidewire.

DES Strut Thickness and Clinical Outcomes After CTO Recanalization: Insights From LATAM CTO Registry. CARDIOVASCULAR REVASCULARIZATION MEDICINE 2023; 53:28-35. [PMID: 36907696 DOI: 10.1016/j.carrev.2023.03.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2022] [Revised: 02/19/2023] [Accepted: 03/02/2023] [Indexed: 03/09/2023]
Abstract
BACKGROUND Ultra-thin strut drug-eluting stent (UTS-DES) may improve outcomes after percutaneous coronary intervention (PCI) but have received limited study in chronic total occlusion (CTO) PCI. AIMS To compare of 1-year incidence of major adverse cardiac events (MACE) between patients who underwent CTO PCI with ultrathin (≤ 75 μm) versus thin (>75 μm) strut DES in the LATAM CTO registry. METHODS Patients were considered for inclusion only if successful CTO PCI was performed and when only one type of stent strut thickness (ultrathin or thin) was used. A propensity score matching (PSM) was computed to produce similar groups in relation to clinical and procedural characteristics. RESULTS Between January 2015 and January 2020, 2092 patients underwent CTO PCI, of whom 1466 were included in the present analysis (475 in the ultra-thin and 991 in the thin strut DES). In unadjusted analysis the UTS-DES group had lower rate of MACE (HR: 0.63 95 % CI 0.42 to 0.94, p = 0.04) and repeat revascularizations (HR: 0.50 95 % CI 0.31 to 0.81, p = 0.02) at 1-year follow-up. After adjustment for confounding factors in a Cox regression model there was no difference in 1-year incidence of MACE between groups (HR: 1.15 95 % CI 0.41 to 2.97, p = 0.85). On PSM of 686 patients (343 in each group) the 1-year incidence of MACE (HR 0.68 95 % CI 0.37-1.23; P = 0.22) and individual components of MACE did not differ between groups. CONCLUSIONS One-year clinical outcomes after CTO PCI were similar with ultrathin and thin strut DES.

Abstract
Percutaneous transcatheter interventions have evolved as standard therapies for a variety of cardiovascular diseases, from revascularization for atherosclerotic vascular lesions to the treatment of structural cardiac diseases. Concomitant technological innovations, procedural advancements, and operator experience have contributed to effective therapies with low complication rates, making early hospital discharge safe and common. Same-day discharge presents numerous potential benefits for patients, providers, and health care systems. There are several key elements that are shared across the spectrum of interventional cardiology procedures to create a successful same-day discharge pathway. These include appropriate patient and procedure selection, close postprocedural observation, predischarge assessments specific for each type of procedure, and the existence of a patient support system beyond hospital discharge. This review provides the rationale, available data, and a framework for same-day discharge across the spectrum of coronary, peripheral, and structural cardiovascular interventions.

Abstract
BACKGROUND Although discouraged, ad hoc chronic total occlusion (CTO) percutaneous coronary intervention (PCI) is occasionally performed. METHODS We examined the clinical, angiographic characteristics, and procedural outcomes of patients who underwent ad hoc CTO PCI in the Prospective Global Registry for the Study of CTO Intervention (PROGRESS-CTO, NCT02061436). RESULTS Of the 10,998 patients included in the registry, 899 (8.2%) underwent ad hoc CTO PCI. The incidence of ad hoc CTO PCI decreased from 18% in 2016 to 3% in 2022. Ad hoc CTO PCI patients had a lower prevalence of comorbidities and less complex angiographic characteristics demonstrated by lower J-CTO score (1.9±1.2 vs 2.4±1.3, P < .001). In these patients, PROGRESS-CTO major adverse cardiovascular events (MACE) (1.9±1.4 vs 2.5±1.7), mortality (1.2±1.0 vs 1.6±1.1), and perforation (1.5±1.2±2.2 vs 1.5) scores were lower (P < .001). Technical success was similar between the groups (86%). MACE were lower in the ad hoc CTO PCI group (.8% vs 2.0%, P=.009). Ad hoc CTO PCI was not associated with MACE after adjusting for potential confounders, odds ratio: .69 (95% confidence interval, .30-1.57). In patients with higher J-CTO scores, planned CTO PCI was associated with higher technical success (P < .001). CONCLUSION Approximately 8% of CTO PCI procedures are performed ad hoc, usually in less complex lesions and patients with lower complication risk. While ad hoc CTO PCI might be appropriate for carefully selected cases, a staged approach is recommended for most CTO PCI.

Abstract
BACKGROUND Coronary artery dissection is a feared and potentially life-threatening complication of percutaneous coronary intervention (PCI). METHODS We examined the clinical, angiographic, and procedural characteristics, and outcomes of coronary dissection at a tertiary care institution. RESULTS Between 2014 and 2019, unplanned coronary dissection occurred in 141 of 10,278 PCIs (1.4%). Median patient age was 68 (60, 78) years, 68% were men, and 83% had hypertension. The prevalence of diabetes (29%), and prior PCI (37%) was high. Most target vessels were significantly diseased: 48% had moderate/severe tortuosity and 62% had moderate/severe calcification. The most common cause of dissection was guidewire advancement (30%), followed by stenting (22%), balloon angioplasty (20%), and guide-catheter engagement (18%). TIMI flow was 0 in 33% and 1-2 in 41% of cases. Intravascular imaging was used in 17% of the cases. Stenting was used to treat the dissection in 73% of patients. There was no consequence of dissection in 43% of patients. Technical and procedural success was 65% and 55%, respectively. In-hospital major adverse cardiovascular events occurred in 23% of patients: 13 (9%) had an acute myocardial infarction (MI), 3 (2%) had emergency coronary artery bypass graft surgery, and 10 (7%) died. During a mean follow up of 1612 days, 28 (20%) patients died, and the rate of target lesion revascularization was 11.3% (n=16). CONCLUSION Coronary artery dissection is an infrequent complication of PCI, but is associated with adverse clinical outcomes, such as death and acute MI.

Abstract
BACKGROUND Distal vessel quality is a key parameter in the global chronic total occlusion (CTO) crossing algorithm. OBJECTIVES The study sought to evaluate the association of distal vessel quality with the outcomes of CTO percutaneous coronary intervention. METHODS We examined the clinical and angiographic characteristics and procedural outcomes of 10,028 CTO percutaneous coronary interventions performed at 39 U.S. and non-U.S. centers between 2012 and 2022. A poor-quality distal vessel was defined as <2 mm diameter or with significant diffuse atherosclerotic disease. In-hospital major adverse cardiac events (MACE) included death, myocardial infarction, urgent repeat target vessel revascularization, tamponade requiring pericardiocentesis or surgery, and stroke. RESULTS A total of 33% of all CTO lesions had poor-quality distal vessel. When compared with good-quality distal vessels, CTO lesions with a poor-quality distal vessel had higher J-CTO (Japanese chronic total occlusion) scores (2.7 ± 1.1 vs 2.2 ± 1.3; P < 0.01), lower technical (79.9% vs 86.9%; P < 0.01) and procedural (78.0% vs 86.8%; P < 0.01) success, and higher incidence of MACE (2.5% vs 1.7%; P < 0.01) and perforation (6.4% vs 3.7%; P < 0.01). A poor-quality distal vessel was independently associated with technical failure and MACE. Poor-quality distal vessels were associated with higher use of the retrograde approach (25.2% vs 14.9%; P < 0.01) and higher air kerma radiation dose (2.4 [IQR: 1.3-4.0] Gy vs 2.0 [IQR: 1.1-3.5] Gy; P < 0.01). CONCLUSIONS A poor-quality distal vessel in CTO lesions is associated with higher lesion complexity, higher need for retrograde crossing, lower technical and procedural success, higher incidence of MACE and coronary perforation, and higher radiation dose.

Abstract
Background: Patients with prediabetes are at increased risk of coronary artery disease (CAD). However, the association between prediabetes and adverse clinical outcomes following percutaneous coronary intervention (PCI) is inconsistent, in contrast to outcomes in patients with diabetes mellitus (DM). Thus, this meta-analysis evaluated the impact of dysglycaemia on PCI outcomes. Methods: The PubMed, Embase, Cochrane, and ClinicalTrials.gov databases were systematically reviewed from inception of databases until June 2022. In 17 studies, outcomes of PCI in patients with prediabetes were compared with patients who were normoglycaemic, and patients with DM. The primary outcome was all-cause mortality at the longest follow-up. Results: Included were 12 prospective and five retrospective studies, with 11,868, 14,894 and 13,536 patients undergoing PCI in the prediabetes, normoglycaemic and DM groups, respectively. Normoglycaemic patients had a statistically lower risk of all-cause mortality, (risk ratio [RR] 0.66, 95% confidence interval [CI] 0.52-0.84), myocardial infarction (MI; RR 0.76, 95% CI 0.61-0.95) and cardiac mortality (RR 0.58, 95% CI 0.39-0.87) compared with prediabetic patients undergoing PCI at the longest follow-up. Patients with prediabetes had a lower risk of all-cause mortality (RR=0.72 [95% CI 0.53-0.97]) and cardiac mortality (RR =0.47 [95% CI 0.23-0.93]) compared with patients with DM who underwent PCI. Conclusion: Among patients who underwent PCI for CAD, the risk of all-cause and cardiac mortality, major adverse cardiovascular events and MI in prediabetic patients was higher compared with normoglycaemic patients but lower compared with patients with DM.

Abstract
Background Endovascular intervention of femoropopliteal chronic total occlusions (CTOs) is technically more complex. However, there is lack of comparative analysis between CTO and non-CTO femoropopliteal interventions. Methods and Results We report procedural details and outcomes of patients treated for femoropopliteal CTO and non-CTO lesions in the XLPAD (Excellence in Peripheral Artery Disease) registry (NCT01904851) between 2006 and 2019. Primary outcomes were procedural success and 1-year major adverse limb events, a composite of all-cause death, target limb revascularization, or major amputation. Analysis included 2895 patients (CTO: n=1516 patients; non-CTO: n=1379 patients) with 3658 lesions (CTO: n=1998 lesions; non-CTO: n=1660 lesions). Conventional balloon angioplasty (20.86% versus 33.48%, P<0.001) or drug-coated balloon angioplasty (1.26% versus 2.93%, P<0.001) were more frequent in the non-CTO group, whereas bare-metal stents (28.09% versus 20.22%, P<0.001) or covered stents (4.08% versus 1.83%, P<0.001) were more frequent in the CTO group. Debulking procedures were more commonly performed in the non-CTO group (41.44% versus 53.13%, P<0.001), despite a similar degree of calcification between the 2 groups. Procedural success was higher in the non-CTO group (90.12% versus 96.79%, P<0.001). Procedural complications were higher in the CTO group (7.21% versus 4.66%, P=0.002), mainly due to excess distal embolization (1.5% versus 0.6%, P=0.015). Adjusted 1-year major adverse limb events were higher in the CTO group (22.47% versus 18.77%, P=0.019), driven mainly by target limb revascularization (19.00% versus 15.34%, P=0.013). Conclusions Procedural success is lower for endovascular treatment of femoropopliteal CTO compared with non-CTO lesions. CTO lesions are associated with higher rates of periprocedural complications and reinterventions after 1 year.

Abstract
BACKGROUND Death is a rare but devastating complication of chronic total occlusion (CTO) percutaneous coronary intervention. METHODS We examined the clinical characteristics and procedural outcomes of patients who died periprocedurally in the Prospective Global Registry for the Study of CTO Interventions (PROGRESS-CTO). RESULTS Of the 12 928 patients who underwent CTO percutaneous coronary intervention between 2012 and 2022, 52 (0.4%) died during the index hospitalization. Patients who died were more likely to have a history of heart failure (43% versus 28%; P=0.023). The J-CTO ([Multicenter CTO Registry of Japan]; 2.8±1.1 versus 2.4±1.3; P=0.019), PROGRESS-CTO mortality (2.6±0.9 versus 1.6±1.1; P<0.001), and PROGRESS-CTO pericardiocentesis (2.9±1.1 versus 1.9±1.3; P<0.001) scores were higher in patients who died. In these patients, the use of left ventricular assist devices was also higher (41% versus 3.5%; P<0.001), and retrograde crossing was more often the first crossing strategy (33% versus 13%; P<0.001). The cause of death was cardiac in 43 patients (83%) and noncardiac in 9 patients (17%). Complications leading to cardiac death were: tamponade in 30 patients (58%), acute myocardial infarction in 9 (17.3%), and cardiac arrest/shock in 4 (7.7%). Noncardiac causes of death were: stroke in 3 (5.8%), renal failure in 2 (3.8%), respiratory distress in 2 (3.8%), and hemorrhagic shock in 2 (3.8%). CONCLUSIONS Approximately 0.4% of patients who underwent CTO percutaneous coronary intervention died during the index hospitalization. The main cause of death was tamponade in 58%. PROGRESS-CTO complication scores might help in risk stratification and procedural planning in patients undergoing CTO percutaneous coronary intervention. REGISTRATION URL: https://www.

Abstract
BACKGROUND The retrograde strategy is a common approach used in complex chronic total occlusion (CTO) percutaneous coronary intervention (PCI). The ERCTO Retrograde score is a tool that aims to predict the likelihood of technical success for retrograde CTO PCI procedures by evaluating 5 parameters: calcification, distal opacification, proximal tortuosity, collateral connection classification, and operator volume. METHODS We evaluated the performance of the ERCTO Retrograde score using data from 2341 patients enrolled in the Prospective Global Registry for the Study of Chronic Total Occlusion Intervention (PROGRESS-CTO) at 35 centers between 2013 and 2023. RESULTS Retrograde CTO PCI was the primary crossing strategy in 871 cases (37.2%) and a secondary crossing strategy in 1467 cases (62.8%). Technical success was achieved in 1,810 cases (77.3%). The technical success rate was higher for primary retrograde cases compared with secondary retrograde cases (79.8% vs 75.9%; P=.031). The ERCTO Retrograde score was positively associated with the likelihood of procedural success. The c-statistic of the ERCTO retrograde score was 0.636 (95% confidence intervals [CI]: .610-.662) for all cases and 0.651 (95% CI: .607-.695) for primary retrograde cases. CONCLUSIONS The ERCTO Retrograde score has modest predictive capacity for technical success in retrograde CTO PCI.

Abstract
BACKGROUND Coronary artery dissection is a feared and potentially life-threatening complication of percutaneous coronary intervention (PCI). METHODS We examined the clinical, angiographic, and procedural characteristics, and outcomes of coronary dissection at a tertiary care institution. RESULTS Between 2014 and 2019, unplanned coronary dissection occurred in 141 of 10,278 PCIs (1.4%). Median patient age was 68 (60, 78) years, 68% were men, and 83% had hypertension. The prevalence of diabetes (29%), and prior PCI (37%) was high. Most target vessels were significantly diseased: 48% had moderate/severe tortuosity and 62% had moderate/severe calcification. The most common cause of dissection was guidewire advancement (30%), followed by stenting (22%), balloon angioplasty (20%), and guide-catheter engagement (18%).

Aortocoronary dissection during percutaneous coronary interventions for chronic total occlusion: Insights from the PROGRESS-CTO registry. Catheter Cardiovasc Interv 2023. [PMID: 37172209 DOI: 10.1002/ccd.30680] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/28/2022] [Revised: 03/27/2023] [Accepted: 04/30/2023] [Indexed: 05/14/2023]
Abstract
BACKGROUND Aortocoronary dissection is a potentially serious complication of chronic total occlusion (CTO) percutaneous coronary intervention (PCI). METHODS We examined the incidence, mechanisms, treatment, and outcomes of aortocoronary dissection among 12,117 CTO PCIs performed between 2012 and 2022 in a large multicenter CTO PCI registry. RESULTS The incidence of aortocoronary dissection was 0.2% (n = 27). Most aortocoronary dissections occurred in the right coronary artery (96.3%, n = 26). The baseline clinical characteristics of patients with and without aortocoronary dissection were similar, except for dyslipidemia, which was less common in patients with aortocoronary dissection (70.4% vs. 86.0%; p = 0.019). The retrograde approach was used more commonly among cases complicated by aortocoronary dissection (59.3% vs. 31.0%; p = 0.002). Technical (74.1% vs. 86.6%; p = 0.049) and procedural (70.4% vs. 85.2%; p = 0.031) success rates were lower among aortocoronary dissection cases, with a similar incidence of in-hospital major adverse cardiovascular events (3.7% vs. 2.0%; p = 0.541). Of the 27 patients with aortocoronary dissection, 19 (70.4%) were treated with ostial stenting and 8 (29.6%) were treated conservatively without subsequent adverse clinical outcomes. No patients required emergency surgery. Follow-up was available for 22 patients (81.5%): during a mean follow up of 767 (±562) days, the incidence of in-stent restenosis was 11.1% (n = 3). CONCLUSIONS Aortocoronary dissection occurred in 0.2% of CTO PCIs performed by experienced operators, was associated with lower technical and procedural success, and was treated most commonly with ostial stenting. None of the patients required emergency cardiac surgery.

Procedural Time and Outcomes of Chronic Total Occlusion Percutaneous Coronary Intervention. Am J Cardiol 2023; 197:55-64.

Abstract
Chronic total occlusion (CTO) percutaneous coronary interventions (PCIs) can be lengthy procedures. We sought to investigate the effect of procedural time on CTO PCI outcomes. We examined the procedural time required for the various steps of CTO PCI in 6,442 CTO PCIs at 40 US and non-US centers between 2012 and 2022. The mean and median procedure times were 129 ± 76 and 112 minutes, respectively, with no significant change over time. The median times from access to wire insertion, guidewire manipulation time, and post crossing were 20, 32, and 53 minutes, respectively. Lesions crossed in <30 minutes were less complex, as reflected by lower Japanese CTO score (1.89 ± 1.19, p <0.001) than lesions that were not successfully crossed (2.88 ± 1.22) and lesions that were crossed in ≥30 minutes (2.85 ± 1.13). The likelihood of successful crossing if crossing was not achieved after 30, 90, and 180 minutes were a 76.7%, 60.7%, and 42.7%, respectively. The parameters independently associated with ≥30 minutes guidewire manipulation time in patients with a primary antegrade approach included left anterior descending target vessel, proximal cap ambiguity, blunt/no stump, occlusion length, previous failed attempt, medium/severe calcification, and medium/severe tortuosity. The mean duration of CTO PCI is approximately 2 hours (∼20% of time for access to wire insertion, ∼30% wire manipulation time, and ∼50% postwiring time). Guidewire crossing time was shorter in less complex lesions and in cases without complications.

The impact of moderate aortic stenosis in acute myocardial infarction: A multicenter retrospective study. Catheter Cardiovasc Interv 2023. [PMID: 37146200 DOI: 10.1002/ccd.30676] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2023] [Revised: 03/31/2023] [Accepted: 04/22/2023] [Indexed: 05/07/2023]
Abstract
BACKGROUND Aortic stenosis (AS) is associated with myocardial ischemia through different mechanisms and may impair coronary arterial flow. However, data on the impact of moderate AS in patients with acute myocardial infarction (MI) is limited. AIMS This study aimed to investigate the impact of moderate AS in patients presenting with acute myocardial infarction (MI). METHODS We conducted a retrospective analysis of all patients who presented with acute MI to all Mayo Clinic hospitals, using the Enterprise Mayo PCI Database from 2005 to 2016. Patients were stratified into two groups: moderate AS and mild/no AS. The primary outcome was all cause mortality. RESULTS The moderate AS group included 183 (13.3%) patients, and the mild/no AS group included 1190 (86.7%) patients. During hospitalization, there was no difference between both groups in mortality. Patients with moderate AS had higher in-hospital congestive heart failure (CHF) (8.2% vs. 4.4%, p = 0.025) compared with mild/no AS patients. At 1-year follow-up, patients with moderate AS had higher mortality (23.9% vs. 8.1%, p < 0.001) and higher CHF hospitalization (8.3% vs. 3.7%, p = 0.028). In multivariate analysis, moderate AS was associated with higher mortality at 1-year (odds ratio 2.4, 95% confidence interval [1.4-4.1], p = 0.002). In subgroup analyses, moderate AS increased all-cause mortality in STEMI and NSTEMI patients. CONCLUSION The presence of moderate AS in acute MI patients was associated with worse clinical outcomes during hospitalization and at 1-year follow-up. These unfavorable outcomes highlight the need for a close follow-up of these patients and for timely therapeutic strategies to best manage these coexisting conditions.

"Catheter hole support": a novel technique for increasing guide catheter support. Curr Probl Cardiol 2023; 48:101754.

Abstract
Percutaneous coronary interventions (PCI) in the setting of tortuosity, calcification, and some types of coronary takeoffs can be challenging. In such cases, the choice of strategies that promote optimal catheter support is essential for the success of the procedure, by facilitating the delivery of the equipment. We have developed a new support technique: "Catheter Hole Support Technique" is a simple, low-cost, and widely available technique that effectively increases catheter support and system stability. To perform the technique, all that is needed is a hole in the catheter at the right spot, made by a 22G needle and a 0.018" shapeable tip support guidewire. We report the steps of this new technique in a successful Right Coronary Artery (RCA) PCI, in the context of a non-ST-elevation myocardial infarction (NSTEMI).

Abstract
BACKGROUND Intravascular ultrasound (IVUS) can assist percutaneous coronary intervention (PCI) of chronic total occlusions (CTO). METHODS We analyzed 8,983 CTO PCIs performed in 8,771 patients between 2012 and 2022 at 39 centers. RESULTS Overall, IVUS was used in 44.5% of the cases, for crossing in 11.5% and for stent optimization in 33.1%. IVUS for stent optimization was used more often for complex lesions with higher prevalence of calcification (51.2% vs 34.3%; P<.001); was associated with lower air kerma radiation dose (1.78 [1.00, 3.09] vs 2.30 (1.35, 3.91) min, P<.001) and contrast volume (190 [138, 258] vs 220 [160, 300] ml, P<.001). Among cases with successful guidewire crossing, those that used IVUS for stent optimization had higher technical (99.3% vs 96.3%; P<.001) and procedural (96.1% vs 94.6%, P=.002) success rates and similar major adverse complication event rates (2.04% vs 1.62%; P=.176). The use of IVUS for stent optimization significantly increased over time. CONCLUSION In a contemporary, multicenter registry, IVUS was used in 44.5% and its use for stent optimization significantly increased over time. Cases where IVUS was used for stent optimization had higher technical and procedural success and similar risk of complications compared with cases where IVUS was not used for stent optimization.

Abstract
BACKGROUND Same day discharge (SDD) following chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has received limited study. METHODS We evaluated the clinical, angiographic, and procedural characteristics of patients discharged the same day versus those kept for overnight observation in the Prospective Global Registry for the Study of Chronic Total Occlusion Intervention (PROGRESS-CTO, NCT02061436). RESULTS Of the 7181 patients who underwent CTO PCI, 943 (13%) had SDD. The SDD rate increased from 3% in 2015 to 21% in 2022. Patients with SDD were less likely to have a history of heart failure (21% vs. 26%, p = 0.005), chronic lung disease (10% vs. 15%, p = 0.001), or anemia (12% vs. 19%, p < 0.001). Technical success (87% vs. 88%, p = 0.289) was similar, but in-hospital major adverse cardiovascular events (0.0% vs. 0.4%, p = 0.041) were lower in SDD. In multivariable logistic regression analysis, prior myocardial infarction odds ratio (OR): 0.71 (95% confidence interval [CI]: 0.59-0.87, p = 0.001), chronic lung disease OR: 0.64 (95% CI: 0.47-0.88, p = 0.006), and increasing procedure time OR: 0.93 (95% CI: 0.91-0.95, p < 0.001, per 10-min increase) were associated with overnight observation, while radial-only access OR: 2.45 (95% CI: 2.03-2.96, p < 0.001) had the strongest association with SDD. In the SDD, 2 (0.4%) of 514 patients were readmitted, due to retroperitoneal bleeding (n = 1) and ischemic stroke (n = 1). CONCLUSION The overall frequency of SDD after CTO PCI was 13% and has been increasing over time. SDD is feasible in select patients following CTO PCI, and radial-only access had the strongest association with SDD.

Abstract
Background: Balloon uncrossable lesions are defined as lesions that cannot be crossed with a balloon after successful guidewire crossing. Methods: We analyzed the association between balloon uncrossable lesions and procedural outcomes of 8671 chronic total occlusions (CTOs) percutaneous coronary interventions (PCIs) performed between 2012 and 2022 at 41 centers. Results: The prevalence of balloon uncrossable lesions was 9.2%. The mean patient age was 64.2 ± 10 years and 80% were men. Patients with balloon uncrossable lesions were older (67.3 ± 9 vs. 63.9 ± 10, p < 0.001) and more likely to have prior coronary artery bypass graft surgery (40% vs. 25%, p < 0.001) and diabetes mellitus (50% vs. 42%, p < 0.001) compared with patients who had balloon crossable lesions. In-stent restenosis (23% vs. 16%. p < 0.001), moderate/severe calcification (68% vs. 40%, p < 0.001), and moderate/severe proximal vessel tortuosity (36% vs. 25%, p < 0.001) were more common in balloon uncrossable lesions. Procedure time (132 (90, 197) vs. 109 (71, 160) min, p < 0.001) was longer and the air kerma radiation dose (2.55 (1.41, 4.23) vs. 1.97 (1.10, 3.40) min, p < 0.001) was higher in balloon uncrossable lesions, while these lesions displayed lower technical (91% vs. 99%, p < 0.001) and procedural (88% vs. 96%, p < 0.001) success rates and higher major adverse cardiac event (MACE) rates (3.14% vs. 1.49%, p < 0.001). Several techniques were required for balloon uncrossable lesions. Conclusion: In a contemporary, multicenter registry, 9.2% of the successfully crossed CTOs were initially balloon uncrossable. Balloon uncrossable lesions exhibited lower technical and procedural success rates and a higher risk of complications compared with balloon crossable lesions.

Abstract
Chronic total occlusion (CTO) percutaneous coronary intervention (PCI) is associated with high incidence of complications. We queried PubMed and the Cochrane Library (last search: October 26, 2022) for CTO PCI-specific periprocedural complication risk scores. We identified 8 CTO PCI-specific risk scores: (1) Angiographic coronary artery perforation (OPEN-CLEAN [Outcomes, Patient Health Status, and Efficiency iN (OPEN) Chronic Total Occlusion (CTO) Hybrid Procedures - CABG, Length (occlusion), EF <50%, Age, CalcificatioN] perforation, c-statistic 0.75): previous coronary artery bypass graft surgery, occlusion length 20 to 60 mm or ≥60 mm, left ventricular ejection fraction (LVEF) <50%, age 50 to 70 years or ≥70 years, heavy calcification. (2) Major adverse cardiovascular events (MACE) (PROGRESS-CTO complication, c-statistic 0.76): age >65 years, lesion length ≥23 mm, retrograde strategy, and (3) MACE (PROGRESS-CTO MACE, c-statistic 0.74): age ≥65 years, female gender, moderate/severe calcification, blunt/no stump, anterograde dissection and re-entry (ADR) or retrograde strategy. (4) All-cause mortality (PROGRESS-CTO mortality, c-statistic 0.80): age ≥65, moderate/severe calcification, LVEF ≤45%, ADR or retrograde strategy. (5) Perforation requiring pericardiocentesis (PROGRESS-CTO pericardiocentesis, c-statistic 0.78): age ≥65 years, moderate/severe calcification, female gender, ADR or retrograde strategy. (6) Acute myocardial infarction (PROGRESS-CTO acute myocardial infarction, c-statistic 0.72): previous coronary artery bypass graft surgery, atrial fibrillation, blunt/no stump. (7) Perforation requiring any treatment (PROGRESS-CTO perforation, c-statistic 0.74): age ≥65 years, moderate/severe calcification, blunt/no stump, ADR, or retrograde strategy. (8) Contrast-induced acute kidney injury (c-statistic 0.84): age ≥75, LVEF <40%, serum creatinine >1.5 mg/100 ml, serum albumin ≤30, 30<albumin≤40 or >40 g/L. There are 8 CTO PCI periprocedural risk scores that may facilitate risk assessment and procedural planning in patients who underwent CTO PCI.
