- Abstract
Background: The management of revascularization of chronic total occlusions (CTOs) remains controversial. Whether specific patients gain survival benefit from CTO revascularization remains unknown., Objectives: We investigated whether (i) patients with CTO have higher N terminal pro-brain natriuretic peptide (NT pro-BNP) levels than patients without CTO, (ii) in patients with CTO, NT pro-BNP levels predict adverse events, and (iii) those with elevated levels benefit from revascularization., Methods: In 392 patients with stable, significant coronary artery disease (CAD) and CTO undergoing coronary angiography, rates of all-cause mortality, cardiovascular death, and a composite (cardiovascular death, myocardial infarction and heart failure hospitalizations) were investigated. Unadjusted and adjusted Cox proportional and Fine and Gray sub-distribution hazard models were performed to determine the association between NT pro-BNP levels and incident event rates in patients with CTO., Results: NT pro-BNP levels were higher in patients with, compared to those without CTO (median 230.0 vs. 177.7 pg/mL, p ≤0.001). Every doubling of NT pro-BNP level in patients with CTO was associated with a > 25% higher rate of adverse events. 111 (28.5%) patients underwent CTO revascularization. In patients with elevated NT pro-BNP levels (> 125 pg/mL), those who underwent CTO revascularization had substantially lower adverse event rates compared to patients without CTO revascularization (adjusted cardiovascular death hazard ratio 0.29, 95% confidence interval (0.09-0.88). However, in patients with low NT pro-BNP levels (≤ 125 pg/mL), event rates were similar in those with and without CTO revascularization., Conclusion: NT pro-BNP levels can help identify individuals who may benefit from CTO revascularization., Competing Interests: Declaration of competing interest CV and GM are full-time Abbott employees and shareholders of Abbott., (Copyright © 2024 Elsevier B.V.

- Abstract
Background: The role of circulating progenitor cells (CPC) in collateral formation that occurs in the presence of chronic total occlusions (CTO) of a coronary artery is not well established. In stable patients with a CTO, we investigated whether CPC levels are associated with (a) collateral development and (b) ischemic burden, as measured by circulating high sensitivity troponin-I (hsTn-I) levels., Methods: CPCs were enumerated by flow cytometry as CD45
med+ blood mononuclear cells expressing CD34 and both CD34 and CD133 epitopes. The association between CPC counts and both Rentrop collateral grade (0, 1, 2, or 3) and hsTn-I levels were evaluated using multivariate regression analysis, after adjusting for demographic and clinical characteristics., Results: In 89 patients (age 65.5, 72% male, 27% Black), a higher CPC count was positively associated with a higher Rentrop collateral grade; [CD34+ adjusted odds ratio (OR) 1.49 95% confidence interval (CI) (0.95, 2.34) P = 0.082] and [CD34+/CD133+ OR 1.57 95% CI (1.05, 2.36) P = 0.028]. Every doubling of CPC counts was also associated with lower hsTn-I levels [CD34+ β -0.35 95% CI (-0.49, -0.15) P = 0.002] and [CD34+/CD133+ β -0.27 95% CI (-0.43, -0.08) P = 0.009] after adjustment., Conclusion: Individuals with higher CPC counts have greater collateral development and lower ischemic burden in the presence of a CTO., Competing Interests: Declaration of competing interest None., (Copyright © 2024 Elsevier B.V.

- Abstract
Background: Cardiac allograft vasculopathy (CAV) is associated with increased mortality in patients with orthotopic heart transplantation (OHT). In addition to immunosuppression, CAV can be treated with percutaneous coronary intervention (PCI) with drug eluting stents (DES) for focal lesions. There is a paucity of data on the rate of DES restenosis in patients with small vessel CAV., Methods: This was a retrospective observational study of 101 coronary vessels treated with a DES diameter of 2.5 mm or less (small vessels) in 61 OHT patients compared to 72 coronary vessels treated with a DES diameter of >2.5 mm (large vessels) in 44 OHT patients at a single center between 2004 and 2022. Baseline demographic data, angiographic characteristics, and clinical outcomes were analyzed., Results: At an average of 1.6 years after DES placement, follow-up angiography revealed in-stent restenosis in 36 (39 %) small vessel interventions and 11 (17 %) large vessel interventions (p = 0.003). Long term mortality did not differ between the groups (59 % vs 59 % at a median of 4.7 [IQR 2.4-7.8] years follow up)., Conclusion: DES restenosis rates are high in small vessel CAV. Additional studies specifically examining PCI in small vessel CAV as well as the potential role for newer treatment strategies for CAV are warranted., Competing Interests: Declaration of competing interest Wissam A.

- Abstract
Although a chronic total occlusion (CTO) in the setting of an acute coronary syndrome is associated with greater risk, the prognosis of patients with a CTO and stable coronary artery disease (CAD) remains unknown. This study aimed to investigate adverse event rates in patients with stable CAD with and without a CTO. In 3,597 patients with stable CAD (>50% coronary luminal stenosis) who underwent cardiac catheterization, all-cause mortality, cardiovascular mortality, and the composite major adverse cardiac event (MACE) rates for cardiovascular death, myocardial infarction, and heart failure hospitalization were evaluated. Cox proportional hazards and Fine and Gray subdistribution hazard models were used to compare event-free survival in patient subsets after adjustment for covariates. Event rates were higher in patients with CTOs than in those without CTOs after adjusting for demographic and clinical characteristics (cardiovascular death hazard ratio [HR] 1.29, 95% confidence interval [CI] 1.05 to 1.57, p = 0.012). Patients with CTO revascularization had lower event rates than those of patients without CTO revascularization (cardiovascular death HR 0.43, CI 0.26 to 0.70, p = 0.001). Those with nonrevascularized CTOs were at particularly great risk when compared with those without CTO (cardiovascular death HR 1.52, CI 1.25 to 1.84, p <0.001). Moreover, those with revascularized CTOs had similar event rates to those of patients with CAD without CTOs. Patients with CTO have higher rates of adverse cardiovascular events than those of patients with significant CAD without CTO. This risk is greatest in patients with nonrevascularized CTO., Competing Interests: Declaration of competing interest Dr. Quyyumi serves on the editorial board of the American Journal of Cardiology., (Copyright © 2024.

- Abstract
Background The survival benefit of revascularization of chronic total occlusion (CTO) of the coronary arteries remains a subject of controversy. We measured high sensitivity troponin-I (hsTn-I) levels as an estimate of myocardial ischemia in patients with stable coronary artery disease, with the hypothesis that (1) patients with CTO have higher levels of hsTn-I than patients without CTO, (2) hsTn-I levels will predict adverse cardiovascular events in patients with CTO, and (3) patients with elevated hsTn-I levels will have a survival benefit from CTO revascularization. Methods and Results In 428 patients with stable coronary artery disease and CTO undergoing coronary angiography, adverse event rates were investigated. Cox proportional hazards models and Fine and Gray subdistribution hazard models were performed to determine the association between hsTn-I level and incident event rates in patients with CTO. HsTn-I levels were higher in patients with compared with those without CTO (median 6.7 versus 5.6 ng/L, P =0.002). An elevated hsTn-I level was associated with higher adverse event rates (adjusted all-cause mortality hazard ratio, 1.19 [95% CI, 1.08-1.32]; P =0.030) for every doubling of hsTn-I level. CTO revascularization was performed in 28.3% of patients. In patients with a high (>median) hsTn-I level, CTO revascularization was associated with substantially lower all-cause mortality (adjusted hazard ratio, 0.26 [95% CI, 0.08-0.88]; P =0.030) compared with those who did not undergo revascularization. In patients with a low ( < median) hsTn-I level, event rates were similar in those with and without CTO revascularization. Conclusions HsTn-I levels may help identify individuals who benefit from CTO revascularization.

- Abstract
Background: The safety and efficacy of intravascular lithotripsy (IVL) for the treatment of calcified distal left main (LM) disease remains unclear, especially compared to rotational atherectomy (RA)., Methods: We retrospectively analyzed the baseline clinical, angiographic, intravascular ultrasound (IVUS) characteristics and procedural outcomes of 107 patients who underwent distal LM percutaneous coronary intervention (PCI) with IVL (with or without adjunct atherectomy) versus RA alone for plaque modification before stenting at a single center between 2020 and 2022., Results: A total of 50 patients underwent calcium modification with IVL with or without adjunct atherectomy and 57 with RA only. The mean age was 73 years and with a high prevalence of diabetes (58.9%), chronic kidney disease (42.1%), prior revascularization (coronary artery bypass graft surgery [36.4%] or prior PCI [32.7%]). Acute coronary syndrome was the primary indication for PCI in over 50% of the patients in both groups. Medina 1-1-1 LM bifurcation disease was identified in 64% and 60% of the IVL and RA groups (p = 0.64) respectively. Final minimum stent area in distal LM (>8.2 mm
2 ), ostial LAD (>6.3 mm2 ) and ostial LCX (>5.0 mm2 ) were achieved in 96%, 85% and 89% of cases treated with IVL respectively and 93%, 93% and 100% of cases treated with RA respectively (LM p = 1.00; LAD p = 0.62; LCX; p = 1.00 for difference between the two groups). Procedural success (technical success without in-hospital major adverse events) was achieved in 98% of the IVL group and 86% of the RA-only group (p = 0.04). There were eight procedural complications (flow-limiting dissection, perforation, or slow/no-reflow) in the RA group compared to four in the IVL group (NS), and one patient in the RA required salvaged mechanical support compared to none in the IVL group., Conclusion: Plaque modification with coronary IVL appears to be efficacious and safe for the treatment of severely calcified distal LM lesions compared to RA only. Larger randomized studies are needed to confirm these findings., (© 2023 Wiley Periodicals LLC.)- Published

- Abstract
Background: Radiation exposure during invasive cardiovascular procedures remains an important health care issue. Lead aprons and shields (LAS) are used to decrease radiation exposure but leave large portions of the body unshielded. The Rampart IC M1128 is a portable radiation shielding system that may significantly attenuate radiation exposure., Methods: Catheterization laboratory teams were randomized in a 1:1 fashion to perform elective invasive cardiovascular procedures utilizing either traditional LAS or the Rampart IC M1128. Radiation exposure was measured using real-time dosimetry monitoring in prespecified anatomic locations on 3 operators (position 1: first operator/fellow; position 2: second operator/attending; and position 3: catheterization laboratory nurse/technologist). Radiation exposure was measured on a per-case basis., Results: In total, 100 consecutive cases were randomized in this study (47 Rampart; 53 LAS). There was no difference in fluoroscopy time (12.3 minutes for Rampart vs 15.4 minutes for LAS; P = .52), dose area product (288 Gy⋅cm
2 for Rampart vs 376.5 Gy⋅cm2 for LAS; P = .52), or scatter radiation (38.8 mRem for Rampart vs 46.8 mRem for LAS; P = .61) between the groups. There was significantly lower total body radiation (in milliroentgen equivalent man) exposure using the Rampart than that using LAS for each team member: position 1-0.1 mRem for Rampart vs 2.2 mRem for LAS; P < .001; position 2-0.1 mRem Rampart vs 3.2 mRem LAS; P < .001; and position 3-0.0 mRem for Rampart vs 0.8 mRem for LAS; P < .001., Conclusions: During routine clinical procedures, the Rampart system significantly decreases total body radiation exposure compared with traditional LAS., (© 2023 The Author(s).)- Published

- Abstract
"Tip-in" technique used in chronic total occlusion revascularization can sometimes be challenging. Herein, we describe a novel method to facilitate "tip-in". After retrograde lesion crossing, the retrograde wire is advanced in a stepwise fashion into the antegrade guide catheter, the guide extension catheter and finally into the antegrade microcatheter. The use of a small lumen guide extension catheter to facilitate "tip-in" works by decreasing the area of operation, hence maximizing the chances of the wire and microcatheter meeting in the same plane. Overall, this newly described "double tip-in" technique can increase procedural success and decrease procedural time., Competing Interests: Declaration of competing interest This research article received no grants or funding., (Copyright © 2022 Elsevier Inc.

- Abstract
Background: There are limited data on the use of bivalirudin for chronic total occlusion (CTO) percutaneous coronary intervention (PCI)., Methods: We compared CTO-PCIs performed using bivalirudin vs unfractionated heparin in the Prospective Global Registry for the Study of Chronic Total Occlusion Intervention (PROGRESS-CTO; NCT02061436). The primary endpoint was net adverse cardiac events (NACE), defined as major adverse cardiac events (MACE) and vascular complications., Results: Between 2012 and 2022, a total of 73 of 9723 procedures (0.75%) were performed using bivalirudin. The J-CTO score (2.4 ± 1.2 vs 2.4 ± 1.3; P=.73) and the PROGRESS-CTO score (1.4 ± 0.9 vs 1.2 ± 1.0; P=.31) were similar in both groups, and the retrograde approach was used less often in the bivalirudin group (15% vs 30%; P<.01). Procedural success (89% vs 85%; P=.35), in-hospital NACE (1.4% vs 2.1%; P>.99), incidence of MACE (0% vs 0.76%; P=.64), and vascular access complications (1.4% vs 0.9%; P=.48) were not different between the 2 groups. On multivariable analysis, use of bivalirudin was not associated with an increased risk of NACE (odds ratio, 0.99; 95% confidence interval, 0.13-7.27)., Conclusion: Bivalirudin is infrequently used during retrograde CTO-PCI. While the incidence of adverse events was similar with unfractionated heparin, larger studies are needed to assess the safety of bivalirudin.

- Abstract
Background Although chronic total occlusions (CTOs) are common in older adults, they are less likely to be offered CTO percutaneous coronary intervention for angina relief than younger adults. The health status impact of CTO percutaneous coronary intervention in adults aged ≥75 years has not been studied. We sought to compare technical success rates and angina-related health status outcomes at 12 months between adults aged ≥75 and <75 years in the OPEN-CTO (Outcomes, Patient Health Status, and Efficiency in Chronic Total Occlusion) registry. Methods and Results Angina-related health status was assessed with the Seattle Angina Questionnaire (score range 0-100, higher scores denote less angina). Technical success rates were compared using hierarchical modified Poisson regression, and 12-month health status was compared using hierarchical multivariable linear regression between adults aged ≥75 and <75 years. Among 1000 participants, 19.8% were ≥75 years with a mean age of 79.5±4.1 years. Age ≥75 years was associated with a lower likelihood of technical success (adjusted risk ratio=0.92 [95% CI, 0.86-0.99; P =0.02]) and numerically higher rates of in-hospital major adverse cardiovascular events (9.1% versus 5.9%, P =0.10). There was no difference in Seattle Angina Questionnaire Summary Score at 12 months between adults aged ≥75 and <75 years (adjusted difference=0.9 [95% CI, -1.4 to 3.1; P =0.44]). Conclusions Despite modestly lower success rates and higher complication rates, adults aged ≥75 years experienced angina-related health status benefits after CTO-percutaneous coronary intervention that were similar in magnitude to adults aged <75 years. CTO percutaneous coronary intervention should not be withheld based on age alone in otherwise appropriate candidates.

- Abstract
Background: Risk stratification before chronic total occlusion (CTO) percutaneous coronary intervention (PCI) is important to inform procedural planning as well as patients and their families. We sought to externally validate the PROGRESS-CTO complication risk scores in the OPEN-CTO registry., Methods: OPEN-CTO is a prospective registry of 1000 consecutive CTO PCIs performed at 12 experienced US centers using the hybrid algorithm. Endpoints of interest were in-hospital all-cause mortality, need for pericardiocentesis, acute myocardial infarction (MI), and major adverse cardiovascular events (MACE) (a composite of all-cause mortality, stroke, periprocedural MI, urgent repeat revascularization, and tamponade requiring pericardiocentesis). Model discrimination was assessed with the area under the curve (AUC) method, and calibration with the observed-versus-predicted probability method., Results: Mean age was 65.4 ± 10.3 year, and 36.5% of patients had prior coronary artery bypass graft. Overall, 41 patients (4.1%) suffered MACE, 9 (0.9%) mortality, 26 (2.6%) acute MI, and 11 (1.1%) required pericardiocentesis. Technical success was achieved in 86.3%. Patients who experienced MACE had higher anatomic complexity, and more often required antegrade dissection/reentry and the retrograde approach. Increasing PROGRESS-CTO MACE scores were associated with increasing MACE rates: 0.5% (score 0-1), 2.4% (score 2), 3.7% (score 3), 4.5% (score 4), 7.8% (score 5), 13.0% (score 6-7). The AUC were as follows: MACE 0.72 (95% confidence interval [CI]: 0.66-0.78), mortality 0.79 (95% CI: 0.66-0.95), pericardiocentesis 0.71 (95% CI: 0.60-0.82), and acute MI 0.57 (95% CI: 0.49-0.66). Calibration was adequate for MACE and mortality, while the models underestimated the risk of pericardiocentesis and acute MI., Conclusions: In a large external cohort of patients treated with the hybrid algorithm by experienced CTO operators, the PROGRESS-CTO MACE, mortality, and pericardiocentesis risk scores showed good discrimination, while the acute MI score had inferior performance., (© 2023 Wiley Periodicals LLC.)

- Abstract
Cardiogenic shock (CS) and cardiac arrest (CA) are the most life-threatening complications of acute myocardial infarction. Although there is a significant overlap in the pathophysiology with approximately half the patients with CS experiencing a CA and approximately two-thirds of patients with CA developing CS, comprehensive guideline recommendations for management of CA + CS are lacking. This paper summarizes the current evidence on the incidence, pathophysiology, and short- and long-term outcomes of patients with acute myocardial infarction complicated by concomitant CA + CS. We discuss the hemodynamic factors and unique challenges that need to be accounted for while developing treatment strategies for these patients. A summary of expert-based step-by-step recommendations to the approach and treatment of these patients, both in the field before admission and in-hospital management, are presented., (Copyright © 2022 Mayo Foundation for Medical Education and Research.

- Abstract
Background: There are limited data on the outcomes of acute myocardial infarction-cardiogenic shock (AMI-CS) in patients with concomitant cancer., Methods: A retrospective cohort of adult AMI-CS admissions was identified from the National Inpatient Sample (2000-2017) and stratified by active cancer, historical cancer, and no cancer. Outcomes of interest included in-hospital mortality, use of coronary angiography, use of percutaneous coronary intervention, do-not-resuscitate status, palliative care use, hospitalization costs, and hospital length of stay., Results: Of the 557,974 AMI-CS admissions during this 18-year period, active and historical cancers were noted in 14,826 (2.6%) and 27,073 (4.8%), respectively. From 2000 to 2017, there was a decline in active cancers (adjusted odds ratio, 0.70 [95% CI, 0.63-0.79]; P < .001) and an increase in historical cancer (adjusted odds ratio, 2.06 [95% CI, 1.89-2.25]; P < .001). Compared with patients with no cancer, patients with active and historical cancer received less-frequent coronary angiography (57%, 67%, and 70%, respectively) and percutaneous coronary intervention (40%, 47%, and 49%%, respectively) and had higher do-not-resuscitate status (13%, 15%, 7%%, respectively) and palliative care use (12%, 10%, 6%%, respectively) (P < .001). Compared with those without cancer, higher in-hospital mortality was found in admissions with active cancer (45.9% vs 37.0%; adjusted odds ratio, 1.29 [95% CI, 1.24-1.34]; P < .001) but not historical cancer (40.1% vs 37.0%; adjusted odds ratio, 1.01 [95% CI, 0.98-1.04]; P = .39). AMI-CS admissions with cancer had a shorter hospitalization duration and lower costs (all P < .001)., Conclusion: Concomitant cancer was associated with less use of guideline-directed procedures. Active, but not historical, cancer was associated with higher mortality in patients with AMI-CS., (© 2022 by the Texas Heart® Institute, Houston.)

- Abstract
Abstract: Despite advances in early revascularization, percutaneous hemodynamic support platforms, and systems of care, cardiogenic shock (CS) remains associated with a mortality rate higher than 50%. Several risk stratification models have been derived since the 1990 s to identify patients at high risk of adverse outcomes. Still, limited information is available on the differences between scoring systems and their relative applicability to both acute myocardial infarction and advanced decompensated heart failure CS. Thus, we reviewed the similarities, differences, and limitations of published CS risk prediction models and herein discuss their suitability to the contemporary management of CS care., Competing Interests: The authors report no conflicts of interest., (Copyright © 2022 by the Shock Society.)

- Abstract
Background: There are limited data on influence of body mass index (BMI) on outcomes of acute myocardial infarction-cardiogenic shock (AMI-CS)., Methods: Adult AMI-CS admissions from 2008 to 2017 were identified from the National Inpatient Sample and stratified by BMI into underweight (<19.9 kg/m
2 ), normal-BMI (19.9-24.9 kg/m2 ) and overweight/obese (>24.9 kg/m2 ). Outcomes of interest included in-hospital mortality, invasive cardiac procedures use, hospitalization costs, and discharge disposition., Results: Of 339,364 AMI-CS admissions, underweight and overweight/obese constitute 2356 (0.7%) and 46,675 (13.8%), respectively. In 2017, compared to 2008, there was an increase in underweight (adjusted odds ratio [aOR] 6.40 [95% confidence interval {CI} 4.91-8.31]; p < 0.001) and overweight/obese admissions (aOR 2.93 [95% CI 2.78-3.10]; p < 0.001). Underweight admissions were on average older, female, with non-ST-segment-elevation AMI-CS, and higher comorbidity. Compared to normal and overweight/obese admissions, underweight admissions had lower rates of coronary angiography (57% vs 72% vs 78%), percutaneous coronary intervention (40% vs 54% vs 54%), and mechanical circulatory support (28% vs 46% vs 49%) (p < 0.001). In-hospital mortality was lower in underweight (32.9% vs 34.1%, aOR 0.64 [95% CI 0.57-0.71], p < 0.001) and overweight/obese (27.6% vs 38.4%, aOR 0.89 [95% CI 0.87-0.92], p < 0.001) admissions. Higher hospitalization costs were seen in overweight/obese admissions while underweight admissions were discharged more often to skilled nursing facilities., Conclusion: Underweight patients received less frequent cardiac procedures and were discharged more often to skilled nursing facilities. Underweight and overweight/obese AMI-CS admissions had lower in-hospital mortality compared to normal BMI., Competing Interests: Declaration of competing interest All authors have reported that they have no relationships relevant to the contents of this paper to disclose., (Copyright © 2021 Elsevier Inc.

- Abstract
This is a focused review looking at the pharmacological support in cardiogenic shock. There are a plethora of data evaluating vasopressors and inotropes in septic shock, but the data are limited for cardiogenic shock. This review article describes in detail the pathophysiology of cardiogenic shock, the mechanism of action of different vasopressors and inotropes emphasizing their indications and potential side effects. This review article incorporates the currently used specific risk-prediction models in cardiogenic shock as well as integrates data from many trials on the use of vasopressors and inotropes. Lastly, this review seeks to discuss the future direction for vasoactive medications in cardiogenic shock., Competing Interests: Declaration of conflicting interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2022.)

- Abstract
Background: Perforation is the most frequent complication of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) and is associated with adverse events including mortality., Methods: Among 1,000 consecutive patients enrolled in 12 center prospective CTO PCI study (OPEN CTO), all perforations were reviewed by the angiographic core-lab. Eighty-nine patients (8.9%) with angiographic perforation were compared to 911 patients without perforation. We sought to describe the clinical and angiographic predictors of angiographic perforation during CTO PCI and develop a risk prediction model., Results: Among eight clinically important candidate variables, independent risk factors for perforation included prior CABG (OR 2.0 [95% CI, 1.2-3.3], p < .01), occlusion length (OR 1.2 per 10 mm increase [95% CI, 1.1-1.3], p < .01), ejection fraction (OR 1.2 per 10% decrease [95% CI, 1.1-1.5], p < .01), age (OR 1.3 per 5 year increase [95%CI, 1.1-1.5], p < .01), and heavy calcification (OR 1.7 [95% CI, 1.0-2.7], p = .04). Three other potential candidate variables, glomerular filtration rate, proximal cap ambiguity, and target vessel, were not independently associated with perforation. The model was internally validated using bootstrapping methods. From the full model, a simplified perforation prediction score (OPEN-CLEAN score: CABG, Length [occlusion], EF < 50%, Age, CalcificatioN) was developed, which discriminated the risk of angiographic perforation well (c-statistics = 0.75) and demonstrated good calibration., Conclusion: This simple 5-variable prediction score may help CTO operators to risk-stratify patients for angiographic perforation using variables available prior to CTO PCI procedures., (© 2021 Wiley Periodicals LLC.)

- Abstract
Remarkable progress has been achieved in chronic total occlusion (CTO) percutaneous coronary intervention (PCI) in recent years, with refinement of the indications and technical aspects of the procedure, imaging, and complication management. Randomized controlled trials and rigorous prospective registries have provided high-quality data on the benefits and risks of CTO PCI. Global collaboration has led to an agreement on nomenclature, indications, endpoint definition, and principles of clinical trial design that have been distilled in global consensus documents such as the CTO Academic Research Consortium. Increased use of preprocedural coronary computed tomography angiography and intraprocedural intravascular imaging, as well as development of novel techniques and structured CTO crossing and complication management algorithms, allow a systematic, stepwise approach to this difficult lesion subset. This state-of-the-art review provides a comprehensive discussion about the most recent developments in the indications, preprocedural planning, technical aspects, complication management, and future directions of CTO PCI., Competing Interests: Funding Support and Author Disclosures Dr Azzalini has received honoraria from Teleflex, Abiomed, Asahi Intecc, Philips, Abbott Vascular, and Cardiovascular Systems, Inc.

- Abstract
Background: Limited studies have evaluated regional disparities in the care of acute myocardial infarction (AMI) patients with cardiac arrest (CA). This study sought to evaluate 18-year national trends, resource utilization, and geographical variation in outcomes in AMI-CA admissions., Methods and Results: Using the National Inpatient Sample (2000-2017), we identified adults with AMI and concomitant CA admitted to the United States census regions of Northeast, Midwest, South, and West. Clinical outcomes of interest included in-hospital mortality, use of coronary angiography, percutaneous coronary intervention (PCI), mechanical circulatory support (MCS), hospitalization costs and length of stay. Of 9,680,257 admissions for AMI, 494,083 (5.1%) had concomitant CA. The West (6.0%) had higher prevalence compared to the Northeast (4.4%), Midwest (5.0%), and South (5.1%), p < 0.001. Admissions in the West had higher rates of STEMI, cardiogenic shock, multiorgan failure, mechanical ventilation, and hemodialysis. Northeast admissions had lower use of coronary angiography (52.0% vs. 67.9% vs. 60.9% vs. 61.5%), PCI (38.7% vs. 51.9% vs. 44.8% vs. 46.7%), and MCS (18.4% vs. 21.8% vs. 18.1%, vs. 20.0%) compared to the Midwest, West and South (all p < 0.001). Compared with the Northeast, adjusted in-hospital mortality was higher in the Midwest (odds ratio [OR] 1.06 [95% confidence interval {CI} 1.03-1.08]), South (OR 1.11 [95% CI 1.09-1.13]) and highest in the West (OR 1.16 [95% CI 1.13-1.18]), all p < 0.001. Temporal trends showed a decline in in-hospital mortality except in the West, which showed a slight increase., Conclusions: There remain significant regional disparities in the management and outcomes of AMI-CA., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2021 Elsevier B.V.

- Abstract
Background: Utilization of inpatient palliative care services (PCS) has been infrequently studied in patients with cardiac arrest complicating acute myocardial infarction (AMI-CA)., Methods: Adult AMI-CA admissions were identified from the National Inpatient Sample (2000-2017). Outcomes of interest included temporal trends and predictors of PCS use and in-hospital mortality, length of stay, hospitalization costs and discharge disposition in AMI-CA admissions with and without PCS use. Multivariable logistic regression and propensity matching were used to adjust for confounding., Results: Among 584,263 AMI-CA admissions, 26,919 (4.6%) received inpatient PCS. From 2000 to 2017 PCS use increased from <1% to 11.5%. AMI-CA admissions that received PCS were on average older, had greater comorbidity, higher rates of cardiogenic shock, acute organ failure, lower rates of coronary angiography (48.6% vs 63.3%), percutaneous coronary intervention (37.4% vs 46.9%), and coronary artery bypass grafting (all p < 0.001). Older age, greater comorbidity burden and acute non-cardiac organ failure were predictive of PCS use. In-hospital mortality was significantly higher in the PCS cohort (multivariable logistic regression: 84.6% vs 42.9%, adjusted odds ratio 3.62 [95% CI 3.48-3.76]; propensity-matched analysis: 84.7% vs. 66.2%, p < 0.001). The PCS cohort received a do- not-resuscitate status more often (47.6% vs. 3.7%), had shorter hospital stays (4 vs 5 days), and were discharged more frequently to skilled nursing facilities (73.6% vs. 20.4%); all p < 0.001. These results were consistent in the propensity-matched analysis., Conclusions: Despite an increase in PCS use in AMI-CA, it remains significantly underutilized highlighting the role for further integrating of these specialists in AMI-CA care., (Copyright © 2021 Elsevier B.V.

- Abstract
Acute myocardial infarction (AMI) with left ventricular (LV) dysfunction patients, the most common cause of cardiogenic shock (CS), have acutely deteriorating hemodynamic status. The frequent use of vasopressor and inotropic pharmacologic interventions along with mechanical circulatory support (MCS) in these patients necessitates invasive hemodynamic monitoring. After the pivotal Evaluation Study of Congestive Heart Failure and Pulmonary Artery Catheterization Effectiveness trial failed to show a significant improvement in clinical outcomes in shock patients managed with a pulmonary artery catheter (PAC), the use of PAC has become less popular in clinical practice. In this review, we summarize currently available literature to summarize the indications, clinical relevance, and recommendations for use of PAC in the setting of AMI-CS., Competing Interests: Conflict-of-interest statement: There is no conflict of interest associated with any of the senior author or other coauthors contributed their efforts in this manuscript., (©The Author(s) 2021.

- Abstract
Background: No previous reports have described the comprehensive care pathways involved in chronic total occlusion percutaneous coronary intervention (CTO PCI)., Methods: In a study of 1,000 consecutive patients undergoing CTO PCI using hybrid approach, a systematic algorithm of selecting CTO PCI strategies, the procedural characteristics, complication rates, and patient reported health status outcomes through 12 months were assessed., Results: Technical success of the index CTO PCI was 86%, with 89% of patients having at least one successful CTO PCI within 12 months. A total of 13.8% underwent CTO PCI of another vessel or reattempt of index CTO PCI within 1 year. At 1 year, the unadjusted major adverse cardiac and cerebral event (MACCE) rate was lower in patients with successful index CTO PCI compared to patients with unsuccessful index CTO PCI (9.4% vs. 14.6%, p = .04). The adjusted hazard ratios of myocardial infarction and death at 12 months were numerically lower in patients with successful index CTO PCI, compared to patients with unsuccessful index CTO PCI. Patients with successful index CTO PCI reported significantly greater improvement in health status throughout 12-months compared to patients with unsuccessful index CTO PCI., Conclusion: CTO-PCI in the real-world often require treatment of second CTO, non-CTO PCI or repeat procedures to treat initially unsuccessful lesions. Successful CTO PCI is associated with numerically lower MACCE at 1 year and persistent symptomatic improvement compared to unsuccessful CTO PCI. Understanding the relationship between the care pathways following CTO PCI and health status benefit requires further study., (© 2020 Wiley Periodicals LLC.)

- Abstract
Background: The effect of body mass index (BMI) on the procedural outcomes and health status (HS) change after chronic total occlusion (CTO) percutaneous coronary intervention (PCI) is largely unknown., Methods: Thousand consecutive patients enrolled in a 12-center prospective CTO PCI study (Outcomes, Patient Health Status, and Efficiency in Chronic Total Occlusion Hybrid Procedures [OPEN-CTO]) were categorized into three groups by baseline BMI (obese ≥30, overweight 25-30, and normal 18.5-25), after excluding seven patients with BMI <18.5. Baseline and follow-up HS at 1 year were quantified using the Seattle Angina Questionnaire, Rose Dyspnea Score, and Personal Health Questionnaire-8 (PHQ-8). Hierarchical, multivariable logistic, and repeated measures linear regression models were used to assess procedural success, major adverse cardiovascular and cerebrovascular events (MACCE), and HS outcomes, as appropriate., Results: The obese and overweight were 47.6% and 37.4%, respectively. While procedure time and contrast dose were similar among the groups, total radiation dose (mGy) was higher with increased BMI (3,019 ± 2,027, 2,267 ± 1,714, 1,642 ± 1,223, p < .01). Procedural success rates, as well as MACCE rates, were similar among the three groups (obese 83.1%, overweight 79.8%, normal 81.9%, p = .47 and 5.1, 8.4, and 8.7%, p = .11). These rates remained similar after adjustment for baseline characteristics. The HS improvement from baseline to 12 months after adjustment was similar in obese and overweight patients compared to normal weight patients., Conclusions: CTO PCI in obese and overweight patients can be performed with similar success and complication rates. Obese and overweight patients derive similar HS benefit from CTO PCI compared to normal weight patients., (© 2020 Wiley Periodicals LLC.)

- Abstract
Objectives: We sought to assess in-hospital and long-term outcomes of retrograde compared with antegrade-only percutaneous coronary intervention for chronic total occlusion (CTO PCI)., Background: Procedural and clinical outcomes following retrograde compared with antegrade-only CTO PCI remain unknown., Methods: Using the core-lab adjudicated OPEN-CTO registry, we compared the outcomes of retrograde to antegrade-only CTO PCI. Primary endpoints included were in-hospital major adverse cardiac and cerebrovascular events (MACCE) (all-cause death, stroke, myocardial infarction [MI], emergency cardiac surgery, or clinically significant perforation) and MACCE at 1-year (all-cause death, MI, stroke, target lesion revascularization, or target vessel reocclusion)., Results: Among 885 single CTO procedures from the OPEN-CTO registry, 454 were retrograde and 431 were antegrade-only. Lesion complexity was higher (J-CTO score: 2.7 vs. 1.9; p < .001) and technical success lower (82.4 vs. 94.2%; p < .001) in retrograde compared with antegrade-only procedures. All-cause death was higher in the retrograde group in-hospital (2 vs. 0%; p = .003), but not at 1-year (4.9 vs. 3.3%; p = .29). Compared with antegrade-only procedures, in-hospital MACCE rates (composite of all-cause death, stroke, MI, emergency cardiac surgery, and clinically significant perforation) were higher in the retrograde group (10.8 vs. 3.3%; p < .001) and at 1-year (19.5 vs. 13.9%; p = .03). In sensitivity analyses landmarked at discharge, there was no difference in MACCE rates at 1 year following retrograde versus antegrade-only CTO PCI. Improvements in Seattle Angina Questionnaire Quality of Life scores at 1-year were similar between the retrograde and antegrade-only groups (29.9 vs 30.4; p = .58)., Conclusions: In the OPEN-CTO registry, retrograde CTO procedures were associated with higher rates of in-hospital MACCE compared with antegrade-only; however, post-discharge outcomes, including quality of life improvements, were similar between technical modalities., (© 2020 Wiley Periodicals LLC.)

- Abstract
Background: Patients with coronary chronic total occlusions (CTO) often have multivessel coronary artery disease. We utilized the OPEN CTO study to evaluate patients who underwent single-vessel versus multivessel percutaneous coronary intervention (PCI) during CTO PCI., Methods: Patients were considered to have undergone single-vessel CTO PCI if they underwent target-vessel only CTO PCI. Patients who underwent multivessel PCI during their index CTO PCI procedure were considered to have undergone multivessel PCI. The additional lesions treated in the multivessel group could be either a separate CTO lesion in a separate epicardial vessel or PCI attempt of any non-CTO stenosis during the same index procedure. Multivariate regression models were used to evaluate predictors of technical success, in-hospital major adverse cardiac and cerebrovascular events (MACCE), and health status measures., Results: Eighty hundred twenty-one patients underwent single-vessel CTO PCI and 179 (17.9%) underwent multivessel PCI during their CTO PCI procedure. Baseline comorbidities, index CTO lesion complexity, and successful crossing strategies used were similar between the two groups. Total procedural time (142.6 versus 115.9 minutes, P < 0.01) and contrast administered (293.8 versus 255.0 ml, P < 0.01) were increased in the multivessel CTO PCI group. Single-vessel versus multivessel PCI during these cases did not affect the likelihood of achieving technical success [odds ratio (OR) 1.05, 95% confidence interval (CI) 0.63-1.75] nor the risk for MACCE (OR 1.23, 95% CI 0.72-2.11). Quality of life (QOL) metrics were similar between the two groups at baseline and 30-day follow-up., Conclusion: There were no significant differences in technical success, in-hospital MACCE rates, or QOL metrics at 30-day follow-up for patients who underwent single-vessel versus multivessel PCI during CTO PCI., (Copyright © 2020 Wolters Kluwer Health, Inc.

- Abstract
Over the past 2 decades, chronic total occlusion (CTO) percutaneous coronary intervention has developed into its own subspecialty of interventional cardiology. Dedicated terminology, techniques, devices, courses, and training programs have enabled progressive advancements. However, only a few randomized trials have been performed to evaluate the safety and efficacy of CTO percutaneous coronary intervention. Moreover, several published observational studies have shown conflicting data. Part of the paucity of clinical data stems from the fact that prior studies have been suboptimally designed and performed. The absence of standardized end points and the discrepancy in definitions also prevent consistency and uniform interpretability of reported results in CTO intervention. To standardize the field, we therefore assembled a broad consortium comprising academicians, practicing physicians, researchers, medical society representatives, and regulators (US Food and Drug Administration) to develop methods, end points, biomarkers, parameters, data, materials, processes, procedures, evaluations, tools, and techniques for CTO interventions. This article summarizes the effort and is organized into 3 sections: key elements and procedural definitions, end point definitions, and clinical trial design principles. The Chronic Total Occlusion Academic Research Consortium is a first step toward improved comparability and interpretability of study results, supplying an increasingly growing body of CTO percutaneous coronary intervention evidence.

- Abstract
Complex coronary artery intervention stresses the limits of both the operator's skills as well as the equipment being used for the procedure. This article is focused on avoiding, recognizing and dealing with device failure and gear entrapment during complex coronary intervention. The operator must understand how to avoid these complications by understanding the limits of devices and the need for adequate vessel preparation. This article focuses on giving the reader an algorithmic approach to recognizing when device failure/entrapment occurs and what specific maneuvers can be done to retrieve different devices and equipment safely., Competing Interests: Disclosure The authors have nothing to disclose., (Copyright © 2020 Elsevier Inc.

- Abstract
Background: There has been increasing utilization of short-term mechanical circulatory support devices for a variety of clinical indications. Many patients have suboptimal iliofemoral access options or reasons why early mobilization is desirable. Axillary artery access is an option for these patients, but little is known about the utility of this approach to facilitate short-term use for circulatory support with microaxial pump devices., Methods: The Axillary Access Registry to Monitor Safety (ARMS) was a prospective, observational multicenter registry to study the feasibility and acute safety of mechanical circulatory support via percutaneous upper-extremity access., Results: One hundred and two patients were collected from 10 participating centers. Successful device implantation was 98% (100 of 102). Devices were implanted for a median of 2 days (interquartile range, 0-5 days; range, 0-35 days). Procedural complications included 10 bleeding events and 1 stroke. There were 3 patients with brachial plexus-related symptoms all consisting of C8 tingling and all arising after multiple days of support. Postprocedural access site hematoma or bleeding was noted in 9 patients. Device explantation utilized closure devices alone in 61%, stent grafts in 17%, balloon tamponade facilitated closure in 15%, and planned surgical explant in 5%. Duration of support appeared to be independently associated with a 1.1% increased odds of vascular complication per day ([95% CI, 0.0%-2.3%] P =0.05)., Conclusions: Percutaneous axillary access for use with microaxial support pumps appears feasible with acceptable rates of bleeding despite early experience. Larger studies are necessary to confirm the pilot data presented here.

- Abstract
Although contemporary chronic total occlusion (CTO) percutaneous coronary intervention (PCI) is performed with high success rates, 10% to 13% of patients presenting with CTOs have chronic kidney disease (CKD), and the comparative safety, efficacy, and health status benefit of CTO PCI in these patients, has not been well defined. We examined the association of baseline renal function with periprocedural major adverse cardiovascular and cerebral events and health status outcomes in 957 consecutive patients (mean age 65.3 ± 10.3 years, 19.4% women, 90.3% white, 23.6 CKD [estimated glomerular filtration rate {eGFR} < 60]) in the OPEN-CTO (Outcomes, Patients Health Status, and Efficiency in Chronic Total Occlusions Registry) study. Hierarchical multivariable regression models were used to examine the independent association of baseline eGFR with technical success, periprocedural complications and change in health status, using Seattle Angina Questionnaire (SAQ) over 1 year. Crude rates of acute kidney injury were higher (13.5% vs 4.4%, p <0.001) and technical success lower (81.8% vs 88.4%, p = 0.01) in patients with CKD. There were no significant differences in other periprocedural complications. After adjustment for confounding factors, there was no significant association of baseline eGFR with technical success or periprocedural major adverse cardiovascular and cerebral events (death, myocardial infarction, emergent bypass surgery, stroke, perforation), whereas patients with lower eGFR had higher rates of acute kidney injury. The difference in SAQ summary score, between patients on the 10th and 90th percentile for baseline eGFR distribution was not clinically significant (1 month: -0.91; 1 year: -3.06 points). In conclusion, CTO PCI success, complication rates, and the health status improvement after CTO PCI are similar in patients across a range of baseline eGFRs., (Copyright © 2020 Elsevier Inc.

- Abstract
Background: The American College of Cardiology/American Heart Association Appropriate Use Criteria were designed to aid clinical decision-making, yet their association with health status outcomes after chronic total occlusion percutaneous coronary intervention (PCI) is unknown., Methods: We analyzed 769 patients with baseline and 1-year health status data after chronic total occlusion PCI. Procedures were categorized as appropriate, may be appropriate, or rarely appropriate. Mean changes in patient-reported health status, assessed by the Seattle Angina Questionnaire (SAQ), were compared across appropriate use criteria categories from baseline to 1 year. Change in SAQ summary score was stratified as little to no benefit (≤10 points), intermediate (10-19 points), large (20-29 points), and very large (≥30 points)., Results: The appropriate use criteria indication was appropriate in 573 patients (74.5%), may be appropriate in 191 (24.8%), and rarely appropriate in 5 (0.7%). Patients in the appropriate group reported greater improvement in SAQ summary scores (27.3±21.3 points) at 1 year compared with the may be appropriate (22.5±20.9; P =0.01). A similar pattern was noted for SAQ angina frequency (mean change 24.0±27.2 versus 18.7±25.6; P =0.02). The appropriate group had the highest proportion of very large improvements in SAQ summary scores (44.5% versus 33.3%; P =0.01)., Conclusions: Among patients undergoing chronic total occlusion PCI, the rate of rarely appropriate PCI was low. The rate of appropriate PCI was high and was associated with the greatest health status improvement at 1 year. A substantial proportion of patients in the may be appropriate group experienced meaningful health status benefits as well.

- Abstract
Background: No previous reports have examined the impact of robotic-assisted (RA) chronic total occlusion (CTO) PCI on procedural duration or safety compared to totally manual CTO PCI., Methods: Among 95 patients who underwent successful PCI of a single CTO lesion at two centers, 49 (52%) were performed RA and were performed 46 (48%) totally manually. Cockpit time was the time the primary operator entered to robotic cockpit until the procedure was complete. "Theoretical" cockpit time in the control group was time the primary operator would have entered the cockpit after lesion crossing until the procedure was complete. Major adverse events (MAEs) were the composite of death, myocardial infarction, clinical perforation, significant vessel dissection, arrhythmia, acute thrombosis, and stroke., Results: The lesion characteristics, procedural time, and contrast dose were similar. All procedures except for one (2%) selected for robotic completion after lesion crossing were completed successfully. The frequency of MAE was similar between groups and there were no in-hospital deaths. The cockpit time was 8 min longer in RA CTO PCI than the theoretical cockpit time in totally manual CTO PCI (40.6 ± 12.7 vs. 32.1 ± 17.8, p < .01)., Conclusion: RA CTO PCI was not associated with excess adverse events compared with totally manual CTO PCI and resulted in an average 41 min cockpit time equaling to 48% of procedure time without radiation exposure or requirement for the primary operator to wear a lead apron. Understanding the relationship between cockpit time and reductions in radiation exposure and lead apron-related orthopedic complications for operators requires future study., (© 2019 Wiley Periodicals, Inc.)

- Abstract
Objectives: This study sought to describe the angiographic characteristics, strategy associated with perforation, and the management of perforation during chronic total occlusion percutaneous coronary intervention (CTO PCI)., Background: The incidence of perforation is higher during CTO PCI compared with non-CTO PCI and is reportedly highest among retrograde procedures., Methods: Among 1,000 consecutive patients who underwent CTO PCI in a 12-center registry, 89 (8.9%) had core lab-adjudicated angiographic perforations. Clinical perforation was defined as any perforation requiring treatment. Major adverse cardiac events (MAEs) were defined as in-hospital death, cardiac tamponade, and pericardial effusion., Results: Among the 89 perforations, 43 (48.3%) were clinically significant, and 46 (51.7%) were simply observed. MAE occurred in 25 (28.0%), and in-hospital death occurred in 9 (10.1%). Compared with nonclinical perforations, clinical perforations were larger in size, more often at a collateral location, had a high-risk shape, and less likely to cause staining or fast filling. Compared with perforations not associated with MAE, perforations associated with MAE were larger in size, more proximal or at collateral location, and had a high-risk shape. When the core lab attributed the perforation to the approach used when the perforation occurred, 61% of retrograde perforations by other classifications were actually antegrade., Conclusions: Larger size, proximal or collateral location, and high-risk shapes of a coronary perforation were associated with MAE. Six of 10 perforations occurred with antegrade approaches among patients who had both strategies attempted. These finding will help emerging CTO operators understand high-risk features of the perforation that require treatment and inform future comparisons of retrograde and antegrade complications., (Copyright © 2019 American College of Cardiology Foundation.

- Abstract
Aims: Chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has been shown to reduce angina and improve quality of life, but the frequency of new or residual angina after CTO PCI and its relationship with titration of anti-anginal medications (AAMs) has not been described., Methods and Results: Among consecutive CTO PCI patients treated at 12 US centres in the OPEN CTO registry, angina was assessed 6 months after the index PCI using the Seattle Angina Questionnaire (SAQ) Angina Frequency scale (a score <100 defined new or residual angina). We then compared the proportion of patients with AAM escalation (defined as an increase in the number or dosage of AAMs between discharge and follow-up) between those with and without 6-month angina. Of 901 patients who underwent CTO PCI, 197 (21.9%) reported angina at 6-months, of whom 80 (40.6%) had de-escalation, 66 (33.5%) had no change, and only 51 (25.9%) had escalation of their AAM by the 6-month follow-up. Rates of AAM escalation were similar when stratifying patients by the ultimate success of the CTO PCI, completeness of physiologic revascularization, presence or absence of angina at baseline, history of heart failure, and by degree of symptomatic improvement after CTO PCI., Conclusions: One in five patients reported angina 6 months after CTO PCI. Although patients with new or residual angina were more likely to have escalation of AAMs in follow-up compared with those without residual symptoms, only one in four patients with residual angina had escalation of AAMs. Although it is unclear whether this finding reflects maximal tolerated therapy at baseline or therapeutic inertia, these findings suggest an important potential opportunity to further improve symptom control in patients with complex stable ischaemic heart disease., (Published on behalf of the European Society of Cardiology.

- Abstract
Background: Limited study has detailed the late-term safety and efficacy of chronic total coronary occlusion (CTO) revascularization among multiple centers applying modern techniques and with newer-generation drug-eluting stents., Methods: Among 20 centers, 222 patients enrolled in the XIENCE coronary stent, performance, and technique (EXPERT) CTO trial underwent CTO percutaneous coronary intervention (PCI) with everolimus-eluting stents (EES). Through planned 4-year follow-up, the primary composite endpoint of major adverse cardiac events (MACE; death, myocardial infarction [MI] and target lesion revascularization) and rates of individual component endpoints and stent thrombosis were determined., Results: Demographic, lesion, and procedural characteristics included prior bypass surgery, 9.9%; diabetes, 40.1%; lesion length, 36.1 ± 18.5 mm; and stent length, 51.7 ± 27.2 mm. By 4 years, MACE rates were 31.6 and 22.4% by the pre-specified ARC and per-protocol definitions, respectively. Clinically-indicated target lesion revascularization at 4 years was 11.3%. In landmark analyses of events beyond the first year of revascularization, the annualized rates of target vessel-related MI and clinically-indicated target lesion revascularization were 0.53 and 1.3%, respectively. Through 4 years, the cumulative definite/probable stent thrombosis rate was 1.7% with no events occurring beyond the initial year of index revascularization., Conclusions: In a multicenter registration trial representing contemporary technique and EES, these results demonstrate sustained long-term safety and effectiveness of EES in CTO percutaneous revascularization and can be used to inform shared decision making with patients being considered for CTO PCI relative to late safety and vessel patency., (© 2019 Wiley Periodicals, Inc.)

- Abstract
Background: Successful chronic total occlusion (CTO) percutaneous coronary intervention (PCI) can markedly reduce angina symptom burden, but many patients often remain on multiple antianginal medications (AAMs) after the procedure. It is unclear when, or if, AAMs can be de-escalated to prevent adverse effects or limit polypharmacy. We examined the association of de-escalation of AAMs after CTO PCI with long-term health status., Methods: In a 12-center registry of consecutive CTO PCI patients, health status was assessed at 6 months after successful CTO PCI with the Seattle Angina Questionnaire and the Rose Dyspnea Scale. Among patients with technical CTO PCI success, we examined the association of AAM de-escalation with 6-month health status using multivariable models adjusting for revascularization completeness and predicted risk of post-PCI angina (using a validated risk model). We also examined predictors and variability of AAMs de-escalation., Results: Of 669 patients with technical success of CTO PCI, AAMs were de-escalated in 276 (35.9%) patients at 1 month. Patients with AAM de-escalation reported similar angina and dyspnea rates at 6 months compared with those whose AAMs were reduced (any angina: 22.5% vs 20%, P = .43; any dyspnea: 51.8% vs 50.1%, P = .40). In a multivariable model adjusting for complete revascularization and predicted risk of post-PCI angina, de-escalation of AAMs at 1 month was not associated with an increased risk of angina, dyspnea, or worse health status at 6 months., Conclusions: Among patients with successful CTO PCI, de-escalation of AAMs occurred in about one-third of patients at 1 month and was not associated with worse long-term health status., (Copyright © 2019 Elsevier Inc.

- Abstract
Background Prior research has shown that providers may infrequently adjust antianginal medications (AAMs) following chronic total occlusion (CTO) percutaneous coronary intervention (PCI). Patient characteristics associated with AAM titration and the variation in postprocedure AAM management after CTO PCI across hospitals have not been reported. We sought to determine the frequency and potential correlates of AAM escalation and de-escalation after CTO PCI. Methods and Results Using the 12-center OPEN CTO registry (Outcomes, Patient Health Status, and Efficiency iN Chronic Total Occlusion Hybrid Procedures), we assessed AAM use at baseline and 6 months after CTO PCI. Escalation was defined as any addition of a new class of AAM or dose increase, whereas de-escalation was defined as a reduction in the number of AAMs or dose reduction. Angina was assessed 6 months after the index CTO PCI attempt using the Seattle Angina Questionnaire Angina Frequency domain. Potential correlates of AAM escalation (vs no change) or de-escalation (vs no change) were evaluated using multivariable modified Poisson regression models. Adjusted variation across sites was evaluated using median rate ratios. AAMs were escalated in 158 (17.5%), de-escalated in 351 (39.0%), and were unchanged at 6-month follow-up in 392 (43.5%). Patient characteristics associated with escalation included lung disease, ongoing angina, and periprocedural major adverse cardiac and cerebral events (periprocedural myocardial infarction, stroke, death, emergent cardiac surgery, or clinically significant perforation), whereas de-escalation was more frequent among patients taking more AAMs, those treated with complete revascularization, and after treatment of non-CTO lesions at the time of the index procedure. There was minimal variation in either escalation (median rate ratio, 1.11; P=0.36) or de-escalation (median rate ratio, 1.10; P=0.20) compared to no change of AAMs across sites. Conclusions Escalation or de-escalation of AAMs was less common than continuation following CTO PCI, with little variation across sites. Further research is needed to identify patients who may benefit from AAM titration after CTO PCI and develop strategies to adjust these medications in follow-up.

- Abstract
Introduction: Women have been under-represented in trials. Due to the dearth of information about CTO-PCI in women and discordance of previous results, sex differences in outcomes in the OPEN-CTO Trial were investigated., Methods: OPEN-CTO is an investigator-initiated, multicenter, prospective observational registry of consecutive CTO patients undergoing PCI at 12 U.S. centers. The one-year outcomes of this trial stratified by sex were examined. Optimal propensity matching was performed to compare outcomes between sexes. Multivariate conditional logistic regression modeling for predictors of procedural success was performed., Results: Women represented 19.6% of the cohort (196/1,000 patients). Women were more likely to report dyspnea as their predominant symptom. Women reported statistically worse physical limitation and poorer quality of life as compared to men. J-CTO scores were similar in males and females. Technical, procedural success and MACE rates were similar in both sexes. Contrast and radiation doses were however significantly lower in women. The SAQ- summary score, RDS, EQ-5D VAS, PHQ-8 scores were all improved to the same degree at 1 year in women as compared to men. Predictors of procedural success revealed that younger age, lower J-CTO score and absence of prior CABG were predictors of procedural success. Sex did not predict procedural success or 1-year MACE in this regression model., Conclusion: This real-world registry revealed that women derive the same benefit from CTO-PCI as men without additional complications and with favorable health status outcomes at 1 year. Consideration of revascularization by PCI in symptomatic women should be considered as part of the treatment when appropriate., (© 2018 Wiley Periodicals, Inc.)

- Abstract
Objectives: This study sought to examine depression prevalence among chronic total occlusion (CTO) patients and compared symptom improvement among depressed and nondepressed patients after percutaneous coronary intervention (PCI)., Background: Depression in cardiovascular patients is common, but its prevalence among CTO patients and its association with PCI response is understudied., Methods: Among 811 patients from the OPEN-CTO (Outcomes, Patient Health Status, and Efficiency in Chronic Total Occlusion Hybrid Procedures) registry, we evaluated change in health status between baseline and 1-year post-PCI, as measured by the Seattle Angina Questionnaire (SAQ) and the Rose Dyspnea Score. Depression was defined using the Personal Health Questionnaire-8. The independent association between health status and depression following PCI was assessed using multivariable regression., Results: Among the 811 patients, 190 (23%) screened positive for major depression, of whom 6.3% were on antidepressant therapy at intervention. Depressed patients experienced more baseline angina, but by 1-year post-PCI they experienced greater improvements than nondepressed patients (change in SAQ Summary: 31.4 ± 22.4 vs. 24.2 ± 20.0; p < 0.001). After adjustment, baseline depressed patients had more improvement in health status (adjusted difference in SAQ Summary improvement, depressed vs. nondepressed: 5.48 ± 1.81; p = 0.003)., Conclusions: Depression is common among CTO PCI patients, but few were treated with antidepressants at baseline. Depressed patients had more severe baseline angina and significant improvement in health status after PCI.

- Abstract
Background: Health status and quality of life improvement after chronic total occlusion (CTO) percutaneous coronary intervention (PCI) among patients with refractory angina has not been reported. We sought to determine the degree of quality of life improvement after CTO PCI in patients with refractory angina., Methods and Results: Among 1000 consecutive patients who underwent CTO PCI in a 12-center registry, refractory angina was defined as any angina (baseline Seattle Angina Questionnaire [SAQ] Angina Frequency score of ≤90) despite treatment with ≥3 antianginal medications. Health status at baseline and 1-year follow-up was quantified using the SAQ. Refractory angina was present at baseline in 148 patients (14.8%). Technical success was achieved in 120 (81.1%) at the initial attempt and major adverse cardiac and cerebral events occurred in 10 (6.8%). There were no procedural deaths. Refractory angina patients were highly symptomatic at baseline with mean SAQ Angina Frequency of 51.1±23.8, SAQ quality of life of 35.3±21.2, and SAQ Summary Score of 47.2±17.9, improving by 32.0±27.8, 35.7±23.9, and 32.1±20.1 at 1 year. Through 1-year follow-up, patients with successful CTO PCI had significantly larger degree of improvement of SAQ Angina Frequency and SAQ Summary Score (35.0±26.8 versus 18.8±28.9, P<0.01; 34.2±19.4 versus 22.5±20.8, P<0.01) compared with unsuccessful CTO PCI., Conclusions: Refractory angina was present in 1 of 7 patients in the OPEN-CTO (Outcomes, Patient Health Status, and Efficiency in Chronic Total Occlusion Hybrid Procedures) registry. Patients with refractory angina experienced large, clinically significant health status improvements that persisted through 12 months, and patients with successful CTO PCI had larger health status improvement than those without.
