Efficacy of a one-catheter concept for transradial coronary angiography.

ABSTRACT: Transradial coronary angiography (TRC) can be performed with a one-catheter approach for the right and left coronary ostium (R/LCO). We investigated the performance of a special diagnostic catheter widely used for the one-catheter-approach, the Tiger (Tiger II, TerumoTM).In a dual center registry we analyzed 1412 TRC-procedures exclusively performed by experienced TRC-operators. We compared the performance of the Tiger with Judkins catheters by retrospectively judging ostial catheter stability during contrast injection, and by measuring contrast use, fluoroscopy time (FT) and complication rate.Poor or failed ostial engagement was found in 40.5% in the Tiger group, compared to 46.6% with the use of Judkins catheters (p<0.183). Ostial instability of the Tiger was found more often during engagement of the LCO than the RCO (34.4% vs. 10.8%, p<0.001), whereas it was similar in the LCO and RCO for Judkins catheters (27.4% vs. 26.7%, p = 0.840). TRC-procedures performed with Tiger catheters were associated with less contrast volume (63.48 ± 29.83mL vs. 82.51 ± 56.58mL, p<0.004) and shorter FT than with Judkins catheters. (198.27 ± 194.8sec vs. 326.85 ± 329.70sec). Forearm hematomas occurred less often with the Tiger (1.2% vs. 6.6%, p< 0.02).The Tiger employed as a single catheter in TRC is an effective tool to achieve lower contrast volume and fluoroscopy time at a low complication rate. Unstable engagement affects predominantly the left coronary artery, but its overall frequency is similar for both, the Tiger and Judkins catheters.

Project description:BackgroundCardiovascular disease (CVD) is the major cause of mortality worldwide. Coronary artery disease (CAD) contributes to half of mortalities caused by CVD. The mainstay of management of CAD is medical therapy and revascularisation. Revascularisation can be achieved via coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI). Peripheral arteries, such as the femoral or radial artery, provide the access to the coronary arteries to perform diagnostic or therapeutic (or both) procedures.ObjectivesTo assess the benefits and harms of the transradial compared to the transfemoral approach in people with CAD undergoing diagnostic coronary angiography (CA) or PCI (or both).Search methodsWe searched the following databases for randomised controlled trials on 10 October 2017: Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, and Web of Science Core Collection. We also searched ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform in August 2017. There were no language restrictions. Reference lists were also checked and we contacted authors of included studies for further information.Selection criteriaWe included randomised controlled trials that compared transradial and transfemoral approaches in adults (18 years of age or older) undergoing diagnostic CA or PCI (or both) for CAD.Data collection and analysisWe used the standard methodological procedures expected by Cochrane. At least two authors independently screened trials, extracted data, and assessed the risk of bias in the included studies. We contacted trial authors for missing information. We used risk ratio (RR) for dichotomous outcomes and mean difference (MD) or standardised mean difference (SMD) for continuous data, with their 95% confidence intervals (CIs). All analyses were checked by another author.Main resultsWe identified 31 studies (44 reports) including 27,071 participants and two ongoing studies. The risk of bias in the studies was low or unclear for several domains. Compared to the transfemoral approach, the transradial approach reduced short-term net adverse clinical events (NACE) (i.e. assessed during hospitalisation and up to 30 days of follow-up) (RR 0.76, 95% CI 0.61 to 0.94; 17,133 participants; 4 studies; moderate quality evidence), cardiac death (RR 0.69, 95% CI 0.54 to 0.88; 11,170 participants; 11 studies; moderate quality evidence). However, short-term myocardial infarction was similar between both groups (RR 0.91, 95% CI 0.81 to 1.02; 19,430 participants; 11 studies; high quality evidence). The transradial approach had a lower procedural success rate (RR 0.97, 95% CI 0.96 to 0.98; 25,920 participants; 28 studies; moderate quality evidence), but was associated with a lower risk of all-cause mortality (RR 0.77, 95% CI 0.62 to 0.95; 18,955 participants; 10 studies; high quality evidence), bleeding (RR 0.54, 95% CI 0.40 to 0.74; 23,043 participants; 20 studies; low quality evidence), and access site complications (RR 0.36, 95% CI 0.22 to 0.59; 16,112 participants; 24 studies; low quality evidence).Authors' conclusionsTransradial approach for diagnostic CA or PCI (or both) in CAD may reduce short-term NACE, cardiac death, all-cause mortality, bleeding, and access site complications. There is insufficient evidence regarding the long-term clinical outcomes (i.e. beyond 30 days of follow-up).

Project description:ObjectiveThe previous meta-analysis has assessed that distal transradial access (dTRA) in anatomical snuffbox is safe and effective for coronary angiography and intervention and can reduce radial artery occlusion. However, since the publication of the previous meta-analysis, several observational studies have been added, so we performed an updated meta-analysis to include more eligible studies to compare distal transradial access in anatomical snuffbox with conventional transradial access (cTRA).MethodPubmed, Embase, and Cochrane Library databases were searched for relevant studies from the literature published until 5 January 2021 to evaluate catheterization/puncture failure, hematoma, radial artery spasm, radial artery occlusion (RAO), access time, fluoroscopy time, radiation dose area product, total procedure time, and hemostatic device removal time. The pooled odds ratio (OR), weighted mean difference (WMD), and standardized mean difference (SMD) with 95% confidence interval (95% CI) were calculated for dichotomous and continuous variables, respectively.ResultsA total of 9,054 patients from 14 studies were included in the meta-analysis, and we found no significant difference in catheterization/puncture failure (OR = 1.94, 95CI [0.97, 3.86], P=0.06), hematoma (OR = 0.97, 95CI [0.55, 1.73], P=0.926), radial artery spasm (OR = 0.76, 95CI [0.43, 1.36], P=0.354), total procedure time (SMD = 0.23, 95CI [-0.21, 0.68], P=0.308), or radiation dose area product (WMD = 216.88 Gy/cm2, 95CI [-126.24, 560.00], P=0.215), but dTRA had a lower incidence of RAO (OR = 0.39, 95CI [0.23, 0.66], P < 0.001), shorter hemostatic device removal time (WMD = -66.62 min, 95CI [-76.68, -56.56], P < 0.001), longer access time (SMD = 0.32, 95CI [0.08, 0.56], P=0.008), and longer fluoroscopy time (SMD = 0.16, 95CI [-0.00, 0.33], P=0.05) than cTRA.ConclusionCompared with the cTRA, the dTRA has a lower incidence of radial artery occlusion and shorter hemostatic device removal time, which is worthy of further evaluation in clinical practice.

Project description:Introduction:Coronary artery angiography using radial artery is one of the methods used for diagnosis of coronary artery disease, which causes physical and psychological problems in patients despite its precise and definite diagnosis. The present study is aimed at investigating the effect of peer group-based education on physical and psychological outcomes of patients undergoing coronary artery angiography through the radial artery. Methodology. The present clinical study was conducted on 60 patients undergoing coronary angiography through the radial artery in Vali-e-Asr educational hospital of Fasa during 2018 to 2019. The participants were divided into peer training and control groups (n = 30 in each group) using permutated block randomization. In the peer training group, the patients received the necessary precare training through peer training during and after angiography care. In the control group, the patients received the routine care by the nurse of the related ward. The peer group's stress, anxiety, and depression levels were evaluated before and after the training. Indeed, their comfort, tolerance, satisfaction, and pain levels were measured by a nurse after angiography at the time of entering the ward. Findings. The results indicated no significant difference between the two groups regarding the mean scores of stress, anxiety, and depression before the intervention (p > 0.05). After the intervention, however, there was a significant difference between the two groups concerning the mean score of anxiety (p < 0.05). Nonetheless, no significant difference was found between the two groups in terms of tolerance, comfort, satisfaction, and pain levels (p > 0.05). Finally, the level of pain decreased in both groups over time (p < 0.001). Conclusion:Peer group-based training was effective in decreasing the mean score of anxiety in the patients undergoing coronary angiography. Thus, this method is recommended to be utilized alongside other methods to train patients before coronary angiography due to its inexpensiveness and lack of side effects as well as not increasing the nurses' workload.
