Use of radial access for chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has been increasing. We examined the clinical characteristics and procedural outcomes of patients who ...underwent CTO PCI with radial versus femoral access in the Prospective Global Registry for the Study of CTO Intervention (PROGRESS‐CTO, NCT02061436). Of 10,954 patients who underwent CTO PCI at 55 centers in 7 countries between 2012 and 2022, 2578 (24%) had a radial only approach. Patients who underwent radial only access were younger (63 ± 10 vs. 65 ± 10, years, p < 0.001), more likely to be men (84% vs. 81%, p = 0.001), and had significantly lower prevalence of comorbidities compared with the femoral access group including diabetes mellitus (39% vs. 45%, p < 0.001) and coronary artery bypass graft surgery (57% vs. 64%, p < 0.001). In addition, radial only cases had lower angiographic complexity with lower J‐CTO and PROGRESS‐CTO scores. After adjusting for potential confounders, radial only access was associated with lower risk of access site complications (odds ratio OR: 0.45, 95% confidence interval CI: 0.22–0.91), similar technical success (OR: 0.87, 95% CI: 0.74–1.04) and major adverse cardiovascular events (MACE) (OR: 0.65, 95% CI: 0.40–1.07), compared with the femoral access group. Radial only access was used in 24% of CTO PCIs and was associated with lower access site complications, and similar technical success and MACE as compared with the femoral access group.
Abstract
Background
Septal haematomas causing left ventricular or biventricular outflow obstruction are rare but known complications of chronic total occlusion (CTO) percutaneous coronary ...intervention (PCI) and can be life-threatening.
Case summary
In this case, we describe the formation of a septal haematoma during retrograde CTO PCI. The patient was initially managed conservatively but became progressively unstable, for which she underwent coiling of the inflow and outflow of the septal perforator. Despite coiling, she developed near complete right ventricular outflow obstruction (based on echocardiography). She was successfully managed with a percutaneous right ventricle assist device, with subsequent resolution of the outflow obstruction.
Discussion
Septal haematomas with resultant outflow obstruction have been uniformly fatal. In our case, the use of a percutaneous right ventricle assist device was life-saving.
The use of mechanical circulatory support (MCS) in chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has received limited study. We analyzed the clinical and angiographic ...characteristics, and procedural outcomes of 7,171 CTO PCIs performed between 2012 and 2021 at 35 international centers. Mean age was 64.5 ± 10 years, mean left ventricular ejection fraction was 50 ± 13%. MCS was used in 4.5%, prophylactically in 78.7%, and urgently in 21.3%. The most common type of MCS overall was Impella CP (Abiomed) (55.5%), followed by intra-aortic balloon pump (14.8%) and TandemHeart (LivaNova Inc.) (10.0%). Prophylactic MCS patients were more likely to have diabetes mellitus (55% vs 42%, p <0.001) and had more complex lesions compared with cases without prophylactic MCS (Japan-CTO score: 2.80 ± 1.22 vs 2.39 ± 1.27, p <0.001). Cases with prophylactic MCS had similar technical (86% vs 87%, p = 0.643) but lower procedural (80% vs 86%, p = 0.028) success rates and higher rates of periprocedural major cardiac adverse events compared with no prophylactic MCS use (6.55% vs 1.68%, p <0.001). Urgent MCS use was associated with lower technical (68% vs 87%, p <0.001) and procedural (39% vs 86%, p <0.001) success rates and higher major cardiac adverse events compared with no-MCS use (32.26% vs 1.68%, p <0.001). The differences persisted in multivariable analyses. In summary, in this contemporary multicenter registry, MCS was used in 4.5% of CTO PCIs, mostly prophylactically (78.7%). Elective MCS cases had similar technical success but a higher risk of complications. Urgent MCS cases had lower technical and procedural success and higher periprocedural major complication rates.
The purpose of this study was to identify sex-specific outcomes of intermediate risk patients undergoing transcatheter aortic valve replacement with the SAPIEN 3 valve.
A survival difference has been ...observed in women as compared with men in inoperable and high-risk patients receiving early-generation balloon-expandable valves for transcatheter aortic valve replacement (TAVR). Whether a sex-specific outcome difference persists with newer-generation valves and in lower-risk patients is unknown.
The PARTNER (Placement of Aortic Transcatheter Valves) II S3 trial included high-risk (HR) (Society of Thoracic Surgeons risk score >8% or heart team determination) and intermediate-risk (IR) (Society of Thoracic Surgeons risk score 4% to 8% or heart team determination) patients with severe symptomatic aortic stenosis who were treated with TAVR with the SAPIEN 3 valve. Patient characteristics and clinical outcomes at 30 days and 1 year were compared by sex.
Between October 2013 and December 2014, 1,661 patients were enrolled: 583 were HR (338 men, 245 women) and 1,078 were IR (666 men, 412 women). In both cohorts, women were more likely than men to be frail (22% vs. 13%; p < 0.001), but less likely to have comorbid conditions of renal insufficiency, coronary artery disease, atrial fibrillation, or chronic obstructive pulmonary disease. Women were more likely to receive ≤23-mm valves (74.1% vs. 11.1%; p < 0.001) and were less likely to receive 29-mm valves (1.4% vs. 35.1%; p < 0.001). In the combined cohorts, there was no difference in mortality for women compared with men at 30 days (2.0% vs. 1.2%; p = 0.20) or 1 year (9.3% vs. 10.2%; p = 0.59). There were no differences in disabling stroke or any stroke at 30 days or 1 year; however, women had an increased rate of minor stroke at 30 days (2.1% vs. 0.7%; p = 0.01). Female sex was associated with increased major vascular complications (7.9% vs. 4.4%; p = 0.003), but not with moderate or severe paravalvular regurgitation. Notably, similar outcomes regarding sex-specific outcomes were obtained within stratified analyses of the HR and IR cohorts.
The study found no apparent sex-specific differences in survival or stroke in this trial of TAVR. This may reflect the changing demographic of patients enrolled, use of newer-generation valves with more sizes available, and more accurate valve sizing techniques.
Background
The comparative efficacy and safety of parallel wiring versus antegrade dissection and re‐entry (ADR) in chronic total occlusion (CTO) percutaneous coronary intervention (PCI) is ...controversial.
Methods
We compared the clinical and angiographic characteristics and outcomes of parallel wiring versus ADR after failed antegrade wiring in a large, multicenter CTO PCI registry.
Results
A total of 1725 CTO PCI procedures with failed antegrade wiring with a single wire were approached with parallel wiring (692) or ADR (1033) at the discretion of the operator. ADR patients were older (65 ± 10 vs. 62 ± 10, years, p < 0.001) and had higher prevalence of comorbidities, such as diabetes mellitus (43% vs. 32%, p < 0.001), prior coronary artery bypass graft surgery (31% vs. 19%, p < 0.001), and lower left ventricular ejection fraction (50 ± 14 vs. 53 ± 11%, p < 0.001). The ADR group had higher J‐CTO (2.8 ± 1.1 vs. 2.1 ± 1.3, p < 0.001) and PROGRESS‐CTO (1.6 ± 1.1 vs. 1.2 ± 1.0, p < 0.001) scores. Equipment use including guidewires, balloons, and microcatheters was higher, and the procedures lasted longer in the ADR group. Technical success (78% vs. 75%, p = 0.046) and major adverse cardiovascular events (composite of all‐cause mortality, stroke, acute myocardial infarction, emergency surgery or re‐PCI, and pericardiocentesis) (3.7% vs. 1.9%, p = 0.029) were higher in the ADR group, with similar procedural success (75% vs. 73%, p = 0.166).
Conclusion
In lesions that could not be crossed with antegrade wiring, ADR was associated with higher technical but not procedural success, and also higher MACE compared with parallel wiring.
This study examined the frequency and outcomes of radial access for chronic total occlusion (CTO) percutaneous coronary intervention (PCI).
Radial access improves the safety of PCI, but its role in ...CTO PCI remains controversial.
We compared the clinical, angiographic, and procedural characteristics of 3,790 CTO interventions performed between 2012 and 2018 via radial-only access (RA) (n = 747) radial-femoral access (RFA) (n = 844) and femoral-only access (n = 2,199) access at 23 centers in the United States, Europe, and Russia.
Patients' mean age was 65 ± 10 years, and 85% were men. Transradial access (RA and RFA) was used in 42% of CTO interventions and significantly increased over time from 11% in 2012 to 67% in 2018 (p < 0.001). RA patients were younger (age 62 ± 10 years vs. 64 ± 10 years and 65 ± 10 years; p < 0.001), less likely to have undergone prior coronary artery bypass graft surgery (18% vs. 39% and 35%; p < 0.001), and less likely to have undergone prior PCI (60% vs. 63% and 66%; p = 0.005) compared with those who underwent RFA and femoral-only access PCI. RA CTO PCI lesions had lower J-CTO (Multicenter CTO Registry in Japan) (2.1 ± 1.4 vs. 2.6 ± 1.3 and 2.5 ± 1.3; p < 0.001) and PROGRESS CTO (Prospective Global Registry for the Study of Chronic Total Occlusion Intervention) complication (2.3 ± 1.9 vs. 3.2 ± 2.0 and 3.2 ± 1.9; p < 0.001) scores. The mean sheath size was significantly smaller in the RA group (6.6 ± 0.7 vs. 7.0 ± 0.6 and 7.3 ± 0.8; p < 0.0001), although it increased with lesion complexity. Antegrade dissection re-entry (20% vs. 33% and 32%; p < 0.001) was less commonly used with RA, whereas use of retrograde techniques was highest with RFA (47%). The overall rates of technical success (89% vs. 88% vs. 86%; p = 0.061), procedural success (86% vs. 85% vs. 85%; p = 0.528), and in-hospital major complication (2.47% vs. 3.40% vs. 2.18%; p = 0.830) were similar in all 3 groups, whereas major bleeding was lower in the RA group (0.55% vs. 1.94% and 0.88%; p = 0.013).
Transradial access is increasingly being used for CTO PCI and is associated with similar technical and procedural success and lower major bleeding rates compared with femoral-only access interventions. (Prospective Global Registry for the Study of Chronic Total Occlusion Intervention PROGRESS CTO; NCT02061436).
Although high body mass index (BMI) is a known risk factor for the development of cardiovascular diseases, people who are overweight or obese often have better outcomes after cardiac procedures. ...Whether this "obesity paradox" is observed in chronic total occlusion (CTO) percutaneous coronary intervention (PCI) is unknown. Therefore, we examined the association of BMI with the outcomes of CTO-PCI in patients from the large, multicenter PROGRESS-CTO registry after stratifying patients into 3 BMI groups.
Preprocedural coronary computed tomography angiography (CCTA) can be useful in procedural planning for chronic total occlusion (CTO) percutaneous coronary intervention (PCI).
We examined the ...clinical, angiographic and procedural characteristics and outcomes of cases with vs. without preprocedural CCTA in PROGRESS-CTO (NCT02061436). Multivariable logistic regression was used to adjust for confounding factors.
Of 7034 CTO PCI cases, preprocedural CCTA was used in 375 (5.3%) with increasing frequency over time. Patients with preprocedural CCTA had a higher prevalence of prior coronary artery bypass graft surgery (39% vs. 27%, p < 0.001) and angiographically unfavorable characteristics including higher prevalence of proximal cap ambiguity (52% vs. 33%, p < 0.001) and moderate/severe calcification (59% vs. 41%, p < 0.001) compared with those without CCTA. CCTA helped resolve proximal cap ambiguity in 27%, identified significant calcium not seen on diagnostic angiography in 18%, changed estimated CTO length by >5 mm in 10%, and was performed as part of initial coronary artery disease work up in 19%. CCTA cases had higher J-CTO (2.6 ± 1.2 vs. 2.3 ± 1.3, p < 0.001) and PROGRESS-CTO (1.3 ± 1.0 vs. 1.2 ± 1.0 p = 0.027) scores. After adjusting for potential confounders, cases with preprocedural CCTA had similar technical success (odds ratio OR: 1.18, 95% confidence interval CI, 0.83–1.67) and incidence of major adverse cardiovascular events (OR: 1.47, 95% CI, 0.72–3.00).
Preprocedural CCTA was used in ~5% of CTO PCI cases. While CCTA may help with procedural planning, especially in complex cases, technical success and MACE were similar with or without CCTA.

Surgical damage to the inferior laryngeal nerve is one of the most feared complications of thyroid surgery. A detailed knowledge of anatomical variations is necessary. Nonrecurrent inferior laryngeal ...nerve is a rare anomaly on the right side and is exceptional on the left. The typical course of the inferior laryngeal nerve is due to the embryological development of the aortic arch and supra-aortic vessels, and nonrecurrence is associated with a vascular anomaly such as a right retroesophageal subclavian artery. The nervous anomaly on the left side is possible only with the occurrence of cardiac dextroposition (situs inversus) and a left retroesophageal subclavian artery. The situation is more dangerous when a nonrecurrent branch of the inferior laryngeal nerve is associated with a recurrent branch. This anomaly does not appear to be associated with a vascular anomaly in all cases. We came across two cases of NRLN after performing 965 thyroid surgeries.
