Radial Access For Percutaneous Coronary Intervention Research Articles

Factors affecting the availability of hybrid cerebral and myocardial revascularization

Aim. To analyze factors affecting the availability of hybrid cerebral and myocardial revascularization by synchronous percutaneous coronary intervention (PCI) and carotid endarterectomy (CEA).Material and methods. This retrospective study included 263 patients with coronary and internal carotid artery involvement undergoing PCI and CEA during the period from 2011 to 2017.Results. The study revealed the following factors increasing the availability of revascularization: hybrid cerebral and myocardial revascularization, successful PCI using drug-eluting stents, postPCI TIMI flow grade 3, and radial access for PCI. The following factors reduced the availability: polyvascular disease >50% in three beds, prior PCI, left ventricular ejection fraction <50%, left coronary artery involvement, living without a family, staged revascularization, CEA before PCI, unsuccessful/complicated PCI with post-PCI TIMI flow grades of 0-1, residual SYNTAX score >9, emergency hospitalization and multiple emergency PCI of the coronary arteries in the long-term follow-up period.Conclusion. Comprehensive analysis of clinical, demographic, anatomical, angiographic, and perioperative factors made it possible to identify predictors that affect the availability of hybrid revascularization.

TCT-773 Procedural Volume and Outcome With Radial or Femoral Access for Percutaneous Coronary Intervention in Patients With ST-segment Elevation Myocardial Infarction

Radial and femoral arteries are usual routes for percutaneous coronary intervention (PCI). Radial access for PCI can reduce vascular bleeding compared with femoral access, and this result in lowering major adverse cardiovascular and cerebrovascular events (MACCE) in patients with acute myocardial

Abstract 13877: Comparison of Incidence of Radial Artery Occlusion in Patients Undergoing Trans-radial Intervention With or Without a Sheath: A Prospective Cohort Study

Introduction: Sheathless transradial access, by decreasing the profile of hardware, is expected to lower the incidence of radial artery occlusion (RAO). Hypothesis: We sought to compare the risk of RAO in patients undergoing coronary intervention with introducer sheath (SG) or without introducer sheath (SLG). Methods: 1251 consecutive patients undergoing 6 French percutaneous coronary intervention (PCI) between January 1, 2009 and December 31, 2013 in Scranton, PA, formed the study cohort. Radial artery patency was assessed using reverse Barbeau’s test and RAO was confirmed by ultrasonography. Unadjusted, adjusted and propensity matched association between type of radial access (SG vs SLG) and RAO were assessed using logistic regression analysis. Results: Mean age was 65 years, 63% were men 37% were diabetics. 78% attained patent hemostasis (PH). Patients in SG had lower pre-discharge RAO [unadjusted (OR: 0.31, 95% CI: 0.21 - 0.46, P < 0.001), adjusted (OR: 0.10, 95% CI: 0.05 - 0.20, P < 0.001) and propensity matched (OR: 0.20, 95% CI: 0.13 - 0.32, P < 0.001)], 24 hours RAO [unadjusted (OR: 0.20, 95% CI: 0.12 - 0.34, P < 0.001), adjusted (OR: 0.12, 95% CI: 0.06 - 0.24, P < 0.001) and propensity matched (OR: 0.13, 95% CI: 0.07 - 0.25, P < 0.001)] and 30 day RAO [unadjusted (OR: 0.28, 95% CI: 0.14 - 0.54, P < 0.001), adjusted (OR: 0.22, 95% CI: 0.10 - 0.50, P < 0.001) and propensity matched (OR: 0.18, 95% CI: 0.10 - 0.40, P < 0.001)], compared to those in SLG. Spontaneous recanalization rates were significantly higher in SG compared to SLG at 24 hours (62% Vs 38%, P = 0.007) but similar at 30 days (38% Vs 50%, P = 0.338) post PCI. Diabetes diagnosis was an effect modifier for RAO at pre-discharge, 24 hours and 30 days post PCI. Conclusions: Sheath use during radial access for PCI, despite diametrically increasing hardware profile, is associated with less RAO, likely by reducing friction induced intimal trauma. Diabetes is an effect modifier in this association.

Utilization of Radial Artery Access for Percutaneous Coronary Intervention for ST-Segment Elevation Myocardial Infarction in New York

This study sought to determine the utilization and outcomes for radial access for percutaneous coronary intervention (PCI) for ST-segment elevation acute myocardial infarction (STEMI) in common practice. Radial access for PCI has been studied considerably, but mostly in clinical trials. All patients undergoing PCI for STEMI in 2009 to 2010 in New York were studied to determine the frequency and the patient-level predictors of radial access. Differences in in-hospital/30-day mortality between radial and femoral access were also studied. Radial access increased from 4.9% in the first quarter of 2009 to 11.9% in the last quarter of 2010. Significant independent predictors were higher body surface area, non-Hispanic ethnicity, Caucasian race, stable hemodynamic state, ejection fraction <30% and ≥50% onset of STEMI from 12to 23 h before the index procedure, and peripheral vascular disease. Mortality was not related to access site after adjustment for covariates (for radial vs. femoral access, adjusted odds ratio: 0.86, 95% confidence interval: 0.59 to 1.25), but the radial access site was trending toward lower mortality for the 9 hospitals that used it for more than 10% of their patients (adjusted odds ratio: 0.61, 95% confidence interval: 0.36 to 1.02). The use of a radial access site for PCI in STEMI patients increased between 2009 and 2010, but was still infrequent in 2010, and was used for lower-risk STEMI patients. There was no significant difference in mortality by access site, but there was a trend toward a mortality advantage for patients with a radial access site among hospitals that used it relatively frequently.

Características operacionais das intervenções coronárias percutâneas em centro que prioriza a utilização do acesso radial

INTRODUÇÃO: O acesso radial tem demonstrado resultados superiores aos do acesso femoral na redução de complicações vasculares e ocorrência de sangramentos associados aos procedimentos coronários percutâneos. Entretanto, por ser procedimento mais elaborado, requer dos operadores curva de aprendizagem para se obter todas as vantagens da técnica. O objetivo deste estudo foi apresentar as características dos procedimentos de um serviço que prioriza a utilização da via radial. MÉTODOS: Registro prospectivo de pacientes submetidos a intervenção coronária percutânea (ICP) pelo acesso radial ou ulnar, em que foram avaliados sucesso angiográfico do procedimento, falência da técnica, taxa de eventos adversos isquêmicos e sangramento grave. Análise pré-especificada do subgrupo que realizou ICP para coronária direita foi realizada, comparando pacientes que utilizaram cateteres Judkins de direita (JR) ou Amplatz. RESULTADOS: Entre abril de 2010 e maio de 2012, 1.117 pacientes realizaram ICP, 1.040 (93,1%) pela via radial e 50 (4,5%), pela ulnar. Sedação foi realizada em 58,5% dos pacientes, a taxa de crossover foi de 1,2% e o sucesso angiográfico, de 96,2%. Cateteres extra backup foram utilizados em 99,1% das ICPs para coronária esquerda, JR em 69,4%, e Amplatz em 27,1% das ICPs para coronária direita. Na comparação entre JR e Amplatz, observou-se maior duração do procedimento, tempo de fluoroscopia, número de cateteres, pré-dilatação da lesão e número de stents implantados no grupo que utilizou cateteres Amplatz, bem como menor sucesso angiográfico. CONCLUSÕES: A utilização do acesso radial na ICP mostrou alto índice de sucesso e baixo índice de eventos cardíacos maiores e de complicações hemorrágicas. O emprego liberal da sedação e de introdutores 6 F associado à escolha de cateteres com maior suporte são características operacionais de nosso centro, que prioriza o uso da técnica radial.

Percutaneous Coronary Intervention Characteristics in a Centre which Prioritizes the use of the Radial Approach

The radial approach has demonstrated superior benefits to the femoral approach in reducing vascular complications and bleeding events associated to percutaneous coronary interventions. However, because this is a more complex procedure, it requires a learning curve to get all of the advantages of the technique. The aim of this study was to present the characteristics of the procedures of a center that prioritizes the use of radial approach. Prospective registry of patients undergoing percutaneous coronary intervention (PCI) using the radial or ulnar access where angiographic success, technical failure, ischemic adverse events and severe bleeding rates were assessed. A pre-specified analysis of the group undergoing PCI for the right coronary artery was performed, comparing patients using Judkins right catheter (JR) or Amplatz catheters. Between April 2010 and May 2012, 1,117 patients underwent PCI, 1,040 (93.1%) by the radial approach and 50 (4.5%) by the ulnar approach. Sedation was performed in 58.5% of the patients, the crossover rate was 1.2%, and angiographic success was 96.2%. Extra backup catheters were used in 99.1% of PCIs for the left coronary artery, JR in 69.4% and Amplatz in 27.1% of the PCIs for the right coronary artery. When the JR and Amplatz were compared, longer procedure duration, longer fluoroscopy time, larger number of catheters, more frequent lesion predilation and higher number of implanted stents were observed in the group using Amplatz catheters as well as lower angiographic success rates. The use of radial access in PCI showed a high success rate and a low rate of major cardiac events and bleeding complications. The liberal use of sedation and 6 F introducer sheaths, associated to catheters with stronger backup force, are characteristics of our center, which prioritizes the use of the radial approach.
