RESUMO

BACKGROUND: Conventional transradial access in women is associated with a lower success rate and a higher incidence of spasm compared to men. To date, the effect of sex on the performance of distal radial access (DRA) has not been fully elucidated. The aim of this study was to assess the impact of sex on catheterization success and other performance parameters of DRA procedures. METHODS: This is a prospective three-center observational study. From August 2020 to September 2022, data from all consecutive patients who underwent DRA for coronary procedures were collected. RESULTS: A total of 868 procedures were registered and stratified into two groups according to sex: women (n = 258) and men (n = 610). Female patients had less favorable baseline characteristics than male patients in terms of absent or weak pulse (29% vs. 17%; P  < 0.001), distal radial diameter (2.2 ±â€…0.3 vs. 2.4 ±â€…0.4 mm; P  < 0.001) and proximal radial diameter (2.5 ±â€…0.7 vs. 2.7 ±â€…0.7 mm; P  = 0.001). No differences in success rates were found in women compared to men (94.2% vs. 96.6%; P  = 0.135), with a higher presence of arterial spasm in women (5.8% vs. 3.0%; P  = 0.044). The preprocedural ultrasound evaluation was the only predictor of DRA success [odds ratio = 20.0 (4.739-83.333); P  < 0.001]. CONCLUSION: In patients undergoing coronary procedures, the success rate of DRA was high regardless of sex, with a higher incidence of arterial spasm in women.

RESUMO

BACKGROUND: Coronary angiography with two catheters is the traditional strategy for diagnostic coronary procedures. TIG I catheter permits to cannulate both coronary arteries, avoiding exchanging catheters during coronary angiography by transradial access. OBJECTIVE: The aim of this study is to evaluate the impact of one-catheter strategy, by avoiding catheter exchange, on coronary catheterization performance and economic costs. METHODS: Transradial coronary diagnostic procedures conducted from January 2013 to June 2017 were collected. One-catheter strategy (TIG I catheter) and two-catheter strategy (left and right Judkins catheters) were compared. The volume of iodinated contrast administered was the primary endpoint. Secondary endpoints included radial spasm, procedural duration (fluoroscopy time) and exposure to ionizing radiation (dose-area product and air kerma). Direct economic costs were also evaluated. For statistical analyses, two-tailed p-values < 0.05 were considered statistically significant. RESULTS: From a total of 1,953 procedures in 1,829 patients, 252 procedures were assigned to one-catheter strategy and 1,701 procedures to two-catheter strategy. There were no differences in baseline characteristics between the groups. One-catheter strategy required less iodinated contrast [primary endpoint; (60-105)-mL vs. 92 (64-120)-mL; p < 0.001] than the two-catheter strategy. Also, the one-catheter group presented less radial spasm (5.2% vs. 9.3%, p = 0.022) and shorter fluoroscopy time [3.9 (2.2-8.0)-min vs. 4.8 (2.9-8.3)-min, p = 0.001] and saved costs [149 (140-160)-€/procedure vs. 171 (160-183)-€/procedure; p < 0.001]. No differences in dose-area product and air kerma were detected between the groups. CONCLUSIONS: One-catheter strategy, with TIG I catheter, improves coronary catheterization performance and reduces economic costs compared to traditional two-catheter strategy in patients referred for coronary angiography.

Resumo Fundamento: A cineangiocoronariografia com dois cateteres é a estratégia tradicional para procedimentos coronarianos de diagnóstico. O cateter TIG I permite canular ambas as artérias coronárias, evitando a troca de cateteres durante a cineangiocoronariografia por acesso transradial. Objetivo: O objetivo deste estudo é avaliar o impacto da estratégia de um cateter, evitando a troca de cateter, no desempenho da coronariografia por cateterismo e nos seus custos econômicos. Métodos: Foram coletados os procedimentos diagnósticos coronarianos transradiais realizados entre janeiro de 2013 e junho de 2017. A estratégia de um cateter (cateter TIG I) e a estratégia de dois cateteres (cateteres coronários direito e esquerdo de Judkins) foram comparadas. O volume de contraste iodado administrado foi o endpoint primário. Os endpoints secundários eram espasmo radial, duração do procedimento (tempo de fluoroscopia) e exposição a radiações ionizantes (produto dose-área e kerma no ar). Os custos econômicos diretos também foram avaliados. Para as análises estatísticas, valores de p < 0,05 bicaudais foram considerados estatisticamente significativos. Resultados: De um total de 1.953 procedimentos em 1.829 pacientes, 252 procedimentos foram atribuídos à estratégia de um cateter e 1.701 procedimentos à estratégia de dois cateteres. Não houve diferenças nas características basais entre os grupos. A estratégia de um cateter exigiu menos contraste iodado [endpoint primário; (60-105) -mL vs. 92 (64-120) -mL; p < 0,001] em comparação com a estratégia de dois cateteres. Além disso, o grupo da estratégia de um cateter apresentou menos espasmo radial (5,2% vs. 9,3%, p = 0,022) e menor tempo de fluoroscopia [3,9 (2,2-8,0) -min vs. 4,8 (2,9-8,3) -min, p = 0,001] e economia de custos [149 (140-160)-€/procedimento vs. 171 (160-183) -€/procedimento; p < 0,001]. Não foram detectadas diferenças no produto dose-área e kerma no ar entre os grupos. Conclusões: A estratégia de um cateter, com cateter TIG I, melhora o desempenho da coronariografia por cateterismo e reduz os custos econômicos em comparação com a estratégia tradicional de dois cateteres em pacientes encaminhados para cineangiocoronariografia.
