Background: Despite the enormous benefits of radial access, this route is associated with a risk of radial artery occlusion (RAO). Objective: We compared the incidence of RAO in patients undergoing transradial coronary angiography and intervention after short versus prolonged hemostasis protocol. Also we assessed the efficacy of rescue 1-hour ipsilateral ulnar artery compression if RAO was observed after hemostasis. Material and Methods. Patients referred for elective transradial coronary procedures were eligible. After 6 F radial sheath removal, patients were randomized to short (3 hours) (n = 495) or prolonged (8 hours) (n = 503) hemostasis and a simple bandage was placed over the puncture site. After hemostasis was completed, oximetry plethysmography was used to assess the patency of the radial artery. Results: One thousand patients were randomized. Baseline characteristics were similar between both groups with average age 61.4 ± 9.4 years (71% male) and PCI performed on half of the patients. The RAO rate immediately after hemostasis was 3.2% in the short hemostasis group and 10.1% in the prolonged group (p < 0.001). Rescue recanalization was successful only in the short group in 56.2% (11/19); at hospital discharge, RAO rates were 1.4% in the short group and 10.1% in the prolonged group (p < 0.001). Conclusion: Shorter hemostasis was associated with significantly less RAO compared to prolonged hemostasis. Rescue radial artery recanalization was effective in > 50%, but only in the short hemostasis group.

BACKGROUND: Routine thrombus aspiration in patients undergoing primary percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI) does not improve clinical outcomes. However, there is remaining uncertainty about the potential benefit in those patients with high thrombus burden, where there is a biological rationale for greater benefit. OBJECTIVES: The purpose of this study was to evaluate the benefit of thrombus aspiration among STEMI patients with high thrombus burden. METHODS: TOTAL (ThrOmbecTomy with PCI vs. PCI ALone in patients with STEMI) was a randomized trial of routine manual thrombectomy versus PCI alone in patients with STEMI (n = 10,732). High thrombus burden (Thrombolysis In Myocardial Infarction thrombus grade ≥3) was a pre-specified subgroup. RESULTS: The primary outcome of cardiovascular (CV) death, MI, cardiogenic shock, or heart failure was not different at 1 year with thrombus aspiration in patients with high thrombus burden (8.1% vs. 8.3% thrombus aspiration; hazard ratio [HR]: 0.97; 95% confidence interval [CI]: 0.84 to 1.13) or low thrombus burden (6.0% vs. 5.0% thrombus aspiration; HR: 1.22; 95% CI: 0.73 to 2.05; interaction p = 0.41). However, among patients with high thrombus burden, stroke at 30 days was more frequent with thrombus aspiration (31 [0.7%] thrombus aspiration vs. 16 [0.4%] PCI alone, HR: 1.90; 95% CI: 1.04 to 3.48). In the high thrombus burden group, thrombus aspiration did not significantly improve CV mortality at 30 days (HR: 0.78; 95% CI: 0.61 to 1.01; p = 0.06) and at 1 year (HR: 0.88; 95% CI: 0.72 to 1.09; p = 0.25). Irrespective of treatment assignment, high thrombus burden was an independent predictor of death (HR: 1.78; 95% CI: 1.05 to 3.01). CONCLUSIONS: In patients with high thrombus burden, routine thrombus aspiration did not improve outcomes at 1 year and was associated with an increased rate of stroke. High thrombus burden is still an important predictor of outcome in STEMI. (A Trial of routine aspiration ThrOmbecTomy with PCI vs. PCI ALone in patients with STEMI [TOTAL]; NCT01149044).

BACKGROUND: During transradial (TR) access, it remains unclear whether differences in baseline patients characteristics and hemostasis care impact the rate of radial artery occlusion (RAO). We sought to compare the rate of RAO after TR access with the 6 French(Fr) Glidesheath Slender (GSS6Fr, Terumo, Japan) or a standard 5 Fr sheath in Japanese and non-Japanese patients. METHODS AND RESULTS: The Radial Artery Patency and Bleeding, Efficacy, Adverse evenT (RAP and BEAT) trial randomized 1,836 patients undergoing TR coronary angiography and/or interventions to receive the GSS6Fr or the standard 5 Fr Glidesheath (GS5Fr, Terumo, Japan). Out of this study population, 1,087 were Japanese patients and 751 non-Japanese patients. The overall incidence of RAO was significantly higher in Japanese patients (3.6% vs. 1.2%, P = 0.002). Use of GSS6Fr was associated with higher rates of RAO than GS5Fr in Japanese patients (5% vs. 2.2%, P = 0.02) and with similar RAO rates in non-Japanese patients (1.3 vs. 1.1%, P = 1). The mean hemostasis time was significantly longer in Japanese patients (378 ± 253 vs. 159 ± 136 min, P < 0.001) and more Japanese patients had a hemostasis time of more than 6 hr (16.2% vs. 4.9%, P < 0.0001). Longer hemostasis time was an independent predictor of RAO (OR per additional hour 1.070, 95% CI 1.008-1.136, P = 0.03). CONCLUSIONS: Use of GSS6Fr was associated with a higher rate of RAO than a standard 5 Fr sheath in Japanese patients but not in non-Japanese patients. Whether improvement in post-procedural care and reduced hemostasis time could impact the incidence of RAO in Japanese patients should be further assessed.

OBJECTIVES: The study sought to evaluate whether prophylactic ipsilateral ulnar artery compression during radial artery hemostasis could reduce the risk of radial artery occlusion (RAO). BACKGROUND: RAO after transradial access (TRA) is a structural complication of TRA. It limits future ipsilateral TRA and may cause transient pain. Maintaining radial artery flow during hemostasis reduces the incidence of acute RAO. Ipsilateral ulnar compression increases radial artery flow and could impact the incidence of RAO. METHODS: Three thousand patients undergoing diagnostic cardiac catheterization using TRA were randomized to receive either standard patent hemostasis protocol (Group I) or prophylactic ipsilateral ulnar compression in addition to patent hemostasis (Group II). Using plethysmography, radial artery patency was evaluated at the time of removal of the compression device as well as 24 h and 30 days after the procedure. The primary study endpoint was 30-day RAO. RESULTS: The primary endpoint, 30-day RAO, was significantly reduced in patients with patent hemostasis and prophylactic ulnar compression compared with standard patent hemostasis (0.9% vs. 3.0%; p = 0.0001). Baseline patient and procedural characteristics were similar between the 2 groups. RAO was significantly reduced by prophylactic ulnar compression at all time intervals (p < 0.0001). CONCLUSIONS: Prophylactic ipsilateral ulnar compression during radial artery hemostasis is an effective, simple, and inexpensive technique that lowers the risk of RAO after TRA.

BACKGROUND: Two large trials have reported contradictory results at 1 year after thrombus aspiration in ST elevation myocardial infarction (STEMI). In a 1-year follow-up of the largest randomised trial of thrombus aspiration, we aimed to clarify the longer-term benefits, to help guide clinical practice. METHODS: The trial of routine aspiration ThrOmbecTomy with PCI versus PCI ALone in Patients with STEMI (TOTAL) was a prospective, randomised, investigator-initiated trial of routine manual thrombectomy versus percutaneous coronary intervention (PCI) alone in 10,732 patients with STEMI. Eligible adult patients (aged ≥18 years) from 87 hospitals in 20 countries were enrolled and randomly assigned (1:1) within 12 h of symptom onset to receive routine manual thrombectomy with PCI or PCI alone. Permuted block randomisation (with variable block size) was done by a 24 h computerised central system, and was stratified by centre. Participants and investigators were not masked to treatment assignment. The trial did not show a difference at 180 days in the primary outcome of cardiovascular death, myocardial infarction, cardiogenic shock, or heart failure. However, the results showed improvements in the surrogate outcomes of ST segment resolution and distal embolisation, but whether or not this finding would translate into a longer term benefit remained unclear. In this longer-term follow-up of the TOTAL study, we report the results on the primary outcome (cardiovascular death, myocardial infarction, cardiogenic shock, or heart failure) and secondary outcomes at 1 year. Analyses of the primary outcome were by modified intention to treat and only included patients who underwent index PCI. This trial is registered with ClinicalTrials.gov, number NCT01149044. FINDINGS: Between Aug 5, 2010, and July 25, 2014, 10,732 eligible patients were enrolled and randomly assigned to thrombectomy followed by PCI (n=5372) or to PCI alone (n=5360). After exclusions of patients who did not undergo PCI in each group (337 in the PCI and thrombectomy group and 331 in the PCI alone group), the final study population comprised 10,064 patients (5035 thrombectomy and 5029 PCI alone). The primary outcome at 1 year occurred in 395 (8%) of 5035 patients in the thrombectomy group compared with 394 (8%) of 5029 in the PCI alone group (hazard ratio [HR] 1·00 [95% CI 0·87-1·15], p=0·99). Cardiovascular death within 1 year occurred in 179 (4%) of the thrombectomy group and in 192 (4%) of 5029 in the PCI alone group (HR 0·93 [95% CI 0·76-1·14], p=0·48). The key safety outcome, stroke within 1 year, occurred in 60 patients (1·2%) in the thrombectomy group compared with 36 (0·7%) in the PCI alone group (HR 1·66 [95% CI 1·10-2·51], p=0·015). INTERPRETATION: Routine thrombus aspiration during PCI for STEMI did not reduce longer-term clinical outcomes and might be associated with an increase in stroke. As a result, thrombus aspiration can no longer be recommended as a routine strategy in STEMI.

BACKGROUND: Radial artery occlusion (RAO) may occur posttransradial intervention and limits the radial artery as a future access site, thus precluding its use as an arterial conduit. In this study, we investigate the incidence and factors influencing the RAO in the current literature. METHODS AND RESULTS: We searched MEDLINE and EMBASE for studies of RAO in transradial access. Relevant studies were identified and data were extracted. Data were synthesized by meta-analysis, quantitative pooling, graphical representation, or by narrative synthesis. A total of 66 studies with 31 345 participants were included in the analysis. Incident RAO ranged between <1% and 33% and varied with timing of assessment of radial artery patency (incidence of RAO within 24 hours was 7.7%, which decreased to 5.5% at >1 week follow-up). The most efficacious measure in reducing RAO was higher dose of heparin, because lower doses of heparin were associated with increased RAO (risk ratio 0.36, 95% CI 0.17-0.76), whereas shorter compression times also reduced RAO (risk ratio 0.28, 95% CI 0.05-1.50). Several factors were found to be associated with RAO including age, sex, sheath size, and diameter of radial artery, but these factors were not consistent across all studies. CONCLUSIONS: RAO is a common complication of transradial access. Maintenance of radial patency should be an integral part of all procedures undertaken through the radial approach. High-dose heparin along with shorter compression times and patent hemostasis is recommended in reducing RAO.

OBJECTIVES: This study sought to compare radial and femoral approaches in patients presenting with ST-segment elevation myocardial infarction (STEMI) and undergoing primary percutaneous coronary intervention (PCI) by high-volume operators experienced in both access sites. BACKGROUND: The exact clinical benefit of the radial compared to the femoral approach remains controversial. METHODS: STEMI-RADIAL (ST Elevation Myocardial Infarction treated by RADIAL or femoral approach) was a randomized, multicenter trial. A total of 707 patients referred for STEMI <12 h of symptom onset were randomized in 4 high-volume radial centers. The primary endpoint was the cumulative incidence of major bleeding and vascular access site complications at 30 days. The rate of net adverse clinical events (NACE) was defined as a composite of death, myocardial infarction, stroke, and major bleeding/vascular complications. Access site crossover, contrast volume, duration of intensive care stay, and death at 6 months were secondary endpoints. RESULTS: The primary endpoint occurred in 1.4% of the radial group (n = 348) and 7.2% of the femoral group (n = 359; p = 0.0001). The NACE rate was 4.6% versus 11.0% (p = 0.0028), respectively. Crossover from radial to femoral approach was 3.7%. Intensive care stay (2.5 ± 1.7 days vs. 3.0 ± 2.9 days, p = 0.0038) as well as contrast utilization (170 ± 71 ml vs. 182 ± 60 ml, p = 0.01) were significantly reduced in the radial group. Mortality in the radial and femoral groups was 2.3% versus 3.1% (p = 0.64) at 30 days and 2.3% versus 3.6% (p = 0.31) at 6 months, respectively. CONCLUSIONS: In patients with STEMI undergoing primary PCI by operators experienced in both access sites, the radial approach was associated with significantly lower incidence of major bleeding and access site complications and superior net clinical benefit. These findings support the use of the radial approach in primary PCI as first choice after proper training.

BACKGROUND: Although radial approach is increasingly used in percutaneous coronary interventions (PCIs) including in acute myocardial infarction (MI), patients with cardiogenic shock have been excluded from comparisons with femoral approach. The aim of our study was to compare clinical outcomes in patients undergoing primary PCI with cardiogenic shock by radial and femoral approach. METHODS AND RESULTS: From 2,663 patients presenting with ST-elevation MI in 2 large volume radial centers, we identified 197 patients (7.4%) with signs of cardiogenic shock immediately before undergoing primary PCI. Radial approach was used in 55% of cases when at least 1 radial artery was weakly palpable, either spontaneously or after intravenous noradrenaline bolus. Patients in the radial group were older (69 ± 12 vs 64 ± 12 years, P = .010), had less diabetes (13% vs 26%, P = .028), and required less often intubation prior PCI (42% vs 66%, P = .0006) or intraaortic balloon pump (36% vs 55%, P = .0096). Mortality at 1 year was 44% in the radial group and 64% in the femoral group (P = .0044). Independent predictors of late mortality included radial approach (hazard ratio [HR] 0.65, 95% CI 0.42-0.98, P = .041), the use of glycoprotein IIb-IIIa receptor inhibitors (HR 0.63, 95% CI 0.40-0.96, P = .032), baseline creatinine ≥110 μmol/L (HR 3.34, 95% CI 2.20-5.12, P < .0001), initial glycemia >200 mg/dL (HR 2.02, 95% CI 1.34-3.11, P = .0008), and age >65 years (HR 1.80, 95% CI 1.18-2.79, P = .006). CONCLUSION: Radial approach was safe and feasible in more than half of the patients with ST-elevation MI and cardiogenic shock treated by primary PCI. After adjustment for baseline and procedural characteristics, radial approach remained associated with better survival. However, prognosis of patients undergoing primary PCI in cardiogenic shock remains poor.
