RESUMEN
BACKGROUND: The Synergy MegatronTM is an everolimus-drug eluting stent that may offer advantages in the treatment of aorto-ostial disease and large proximal vessels. AIMS: To report the short- to medium-term clinical outcomes from the European Synergy MegatronTM Implanters' Registry. METHODS: This registry was an investigator-initiated study conducted at 14 European centers. The primary outcome was target lesion failure (TLF), defined as the composite of cardiovascular death, target vessel myocardial infarction (MI), and target lesion revascularisation. RESULTS: Five hundred seventy-five patients underwent PCI with MegatronTM between 2019 and 2021. Patients were 69 ± 12 years old, 26% had diabetes mellitus, 24% had moderate-severe left ventricular impairment and 59% presented with an acute coronary syndrome. 15% were deemed prohibitively high risk for surgical revascularisation. The target vessel involved the left main stem in 55%, the ostium of the RCA in 13% and was a true bifurcation (Medina 1,1,1) in 50%. At 1 year, TLF was observed in 40 patients, with 26 (65%) occurring within the first 30 days. The cumulative incidence of TLF was 4.5% at 30 days and 8.6% (95% CI 6.3-11.7) at 1 year. The incidence of stent thrombosis was 0.5% with no late stent thromboses. By multivariate analysis, the strongest independent predictors of TLF were severe left ventricular impairment (HR 3.43, 95% CI: 1.67-6.76, p < 0.001) and a target vessel involving the left main (HR 4.00 95% CI 1.81-10.15 p = 0.001). CONCLUSIONS: Use of the Synergy MegatronTM everolimus eluting stent in a 'real-world' setting shows favorable outcomes at 30 days and 1 year.

BACKGROUND: Currently, transradial access (TRA) is the recommended access for coronary procedures because of increased safety, with radial artery occlusion (RAO) being its most frequent complication, which will increasingly affect patients undergoing multiple procedures during their lifetimes. Recently, distal radial access (DRA) has emerged as a promising alternative access to minimize RAO risk. A large-scale, international, randomized trial comparing RAO with TRA and DRA is lacking. OBJECTIVES: The aim of this study was to assess the superiority of DRA compared with conventional TRA with respect to forearm RAO. METHODS: DISCO RADIAL (Distal vs Conventional Radial Access) was an international, multicenter, randomized controlled trial in which patients with indications for percutaneous coronary procedure using a 6-F Slender sheath were randomized to DRA or TRA with systematic implementation of best practices to reduce RAO. The primary endpoint was the incidence of forearm RAO assessed by vascular ultrasound at discharge. Secondary endpoints include crossover, hemostasis time, and access site-related complications. RESULTS: Overall, 657 patients underwent TRA, and 650 patients underwent DRA. Forearm RAO did not differ between groups (0.91% vs 0.31%; P = 0.29). Patent hemostasis was achieved in 94.4% of TRA patients. Crossover rates were higher with DRA (3.5% vs 7.4%; P = 0.002), and median hemostasis time was shorter (180 vs 153 minutes; P < 0.001). Radial artery spasm occurred more with DRA (2.7% vs 5.4%; P = 0.015). Overall bleeding events and vascular complications did not differ between groups. CONCLUSIONS: With the implementation of a rigorous hemostasis protocol, DRA and TRA have equally low RAO rates. DRA is associated with a higher crossover rate but a shorter hemostasis time.

BACKGROUND: Transradial access (TRA) has become the default access method for coronary diagnostic and interventional procedures. As compared to transfemoral access, TRA has been shown to be safer, cost-effective and more patient-friendly. Radial artery occlusion (RAO) represents the most frequent complication of TRA, and precludes future coronary procedures through the radial artery, the use of the radial artery as a conduit for coronary artery bypass grafting or as arteriovenous fistula for patients on hemodialysis. Recently, distal radial access (DRA) has emerged as a promising alternative to TRA, yielding potential for minimizing the risk of RAO. However, an international multicenter randomized comparison between DRA, and conventional TRA with respect to the rate of RAO is still lacking. TRIAL DESIGN: DISCO RADIAL is a prospective, multicenter, open-label, randomized, controlled, superiority trial. A total of 1300 eligible patients will be randomly allocated to undergo coronary angiography and/or percutaneous coronary intervention (PCI) through DRA or TRA using the 6 Fr Glidesheath Slender sheath introducer. Extended experience with both TRA and DRA is required for operators' eligibility and optimal evidence-based best practice to reduce RAO systematically implemented by protocol. The primary endpoint is the incidence of forearm RAO assessed by vascular ultrasound at discharge. Several important secondary endpoints will also be assessed, including access-site cross-over, hemostasis time, and access-site related complications. SUMMARY: The DISCO RADIAL trial will provide the first large-scale multicenter randomized evidence comparing DRA to TRA in patients scheduled for coronary angiography or PCI with respect to the incidence of RAO at discharge.

BACKGROUND AND AIMS: Coronary calcification remains a significant challenge for the contemporary interventional cardiologist. We aim to describe the use of intravascular lithotripsy (IVL) in a range of real-world settings. METHODS: A retrospective two-center analysis of patients treated with IVL between June 2018 and November 2019. Technical and procedural success, as well as procedural complications and 30-day outcomes (death, myocardial infarction, or repeat target vessel revascularization), was recorded. RESULTS: Sixty-five patients underwent IVL: 80% were male and the mean age was 70.1 ± 12.0 years. 54% of patients presented with acute coronary syndrome (ACS) and 68% of patients had intracoronary imaging. Twelve patients required IVL within pre-existing stents, and 12 underwent IVL in the left main stem. All balloons were successfully delivered with 98.5% procedural success. There was a significant gain in MLA post PCI of 261.9 ± 100% following IVL. There were two procedural complications. At 30-day follow-up, there was one death, and one patient required a repeat procedure due to stent underexpansion. CONCLUSIONS: In this largest real-world series of imaging-guided IVL for calcified lesions to date, we demonstrate that IVL is deliverable, safe, and effective at calcium modification especially when intracoronary imaging is used.
RESUMEN
OBJECTIVES: This study aimed to examine the cost of coronary syndrome treated with percutaneous coronary intervention (PCI) and 30-day unplanned readmissions. BACKGROUND: There is limited understanding of the hospital cost of index PCI and 30-day unplanned readmissions. METHODS: Patients undergoing PCI between 2010 and 2014 in the U.S. Nationwide Readmission Database were included. The primary outcome was total cost defined by cost of index PCI and first unplanned readmission within 30 days. RESULTS: This analysis included 2,294,244 patients who underwent PCI, and the mean cost was $23,541 ± $20,730 (~$10.8 billion/year). There was a modest increase in cost over the study years of 17.5%. Of the 9.4% with an unplanned readmission within 30 days, the mean total cost was $35,333 ± 24,230 versus $22,323 ± 19,941 for those not readmitted. The variables most strongly associated with the highest quartile of cost were heart failure (adjusted odds ratio (aOR) 25.60 [95% CI 21.59-30.35]), need for circulatory support (aOR 11.62 [10.13-13.32]), periprocedural coronary artery bypass graft (CABG, aOR 585.08 [357.85-956.58]), and readmission within 30 days (aOR 24.49 [22.40-26.77]). An acute kidney injury (AKI; 8.5%), major bleed (0.8%), vascular injury (0.8%), or need for periprodedural CABG (1.4%) had an average increased cost of $21,935; $30,898; $27,875; and $43,005, respectively, compared to PCI without adverse outcome. CONCLUSIONS: The annual 30-day hospital cost of PCI is approximately $10.8 billion, and the costs associated with in-hospital adverse events, particularly the need for AKI and periprocedural CABG, were significant.

BACKGROUND: Patients with complex high-risk coronary anatomy, such as those with a last remaining patent vessel (LRPV), are increasingly revascularized with percutaneous coronary intervention (PCI) in contemporary practice. There are limited data on the outcomes of these high-risk procedures. METHODS: We analyzed a large longitudinal PCI cohort (2007-2014, n=501 841) from the British Cardiovascular Intervention Society database. Clinical, demographic, procedural, and outcome data were analyzed by dividing patients into 2 groups; LRPV group (n=2432) and all other PCI groups (n=506 691). RESULTS: Patients in the LRPV PCI group were older, had more comorbidities, and higher prevalence of moderate-severe left ventricular systolic dysfunction. Mortality was higher in the LRPV PCI group during hospital admission (12 % versus 1.5 %, P<0.001), at 30 days (15% versus 2%, P<0.001), and at one-year (24% versus 5%, P<0.001). In a propensity score matching analysis the adjusted risk of mortality during index admission (odds ratio, 2.05 [95% CI, 1.65-2.44], P<0.001), at 30 days (odds ratio, 2.13 [95% CI, 1.78-2.5], P<0.001), at 1 year (odds ratio, 1.81 [95% CI, 1.59-2.03], P<0.001), and in-hospital major adverse cardiovascular events (odds ratio, 1.8 [95% CI, 1.42-2.19], P<0.001) were higher in LRPV PCI group as compared to control group. In sensitivity analyses, similar clinical outcomes were observed irrespective of which major epicardial coronary artery was treated. CONCLUSIONS: In this contemporary cohort, patients who had PCI to their LRPV had a higher-risk profile and more adverse clinical outcomes, irrespective of the vessel treated.

SUMMARY: A 62-year-old female was admitted with severe left-sided chest pain, nausea and pre-syncope. She had widespread T wave inversion on ECG and elevated troponins and was suspected to have an acute coronary syndrome event. Invasive coronary angiogram revealed normal coronary anatomy with no flow-limiting lesions. Echocardiography and cardiac MRI revealed impaired left ventricular (LV) systolic impairment, a mobile LV apical thrombus and a moderate global pericardial effusion with no significant compromise. Full blood count analysis indicated the patient to have significant eosinophilia, and the patient was diagnosed with idiopathic eosinophilic myocarditis. She was commenced on Prednisolone and Apixaban, and eosinophil levels returned to normal after 10 days of steroids. Over the course of 3 months, the patient had a complete recovery of her LV function and resolution of the LV thrombus. This case highlights a rare, reversible case of idiopathic eosinophilic myocarditis which may present similar to acute coronary syndrome. LEARNING POINTS: Eosinophilic myocarditis (EM) is a rare disease that can exhibit symptoms similar to acute coronary syndrome events.The diagnosis of EM should be considered in patients with chest pain, normal coronary angiogram and pronounced eosinophilia levels.Endomyocardial biopsy is the gold standard diagnostic tool; however, it has a low sensitivity detection rate and its use is not indicated in some patients.Echocardiography is useful in the initial detection of cardiac involvement and complications. However, echocardiography lacks diagnostic specificity for all forms of myocarditis including EM.Cardiac magnetic resonance is a useful method and may add in diagnosing all forms of myocarditis including EM.Patients with EM should be identified promptly and treated with high doses of oral glucocorticoid to reduce the risk of permanent cardiac dysfunction.
RESUMEN
BACKGROUND: Whether cannabis use worsens outcomes in coronary heart disease is unknown and no previous study has evaluated the outcomes for patients who undergo percutaneous coronary intervention (PCI) according to cannabis use. METHODS: We analysed patients in the National Inpatient Sample between 2004 and 2014 who underwent PCI and evaluated rates, predictors and outcomes of patients according to cannabis misuse defined by cannabis abuse or dependence. RESULTS: A total of 7 306 012 patients were included and 32 765 cannabis misusers (0.4%). Cannabis misusers were younger (49.5 vs 64.6 years, P < .001) and were more likely to be male (82.7% vs 66.3%, P < .001). There was also a greater proportion of patients who were of black ethnicity in the cannabis misuse group (27.7% vs 7.9%, P < .001) and fewer elective admissions (7.8% vs 27.6%, P < .001). There was no difference in in-hospital mortality (OR 1.06 95% CI 0.80-1.40, P = .67), bleeding (OR 0.94 95% CI 0.77-1.15, P = .55) and stroke/transient ischaemic attack (OR 1.19 95% CI 0.98-1.45, P = .084) compared with non-cannabis misusers. Cannabis misusers had significantly lower odds of in-hospital vascular complications (OR 0.73 95% CI 0.58-0.90, P = .004). CONCLUSIONS: Our results suggest that cannabis misusers are more likely to be male, of black ethnicity and from the lowest quartile of income, but there was no evidence that cannabis misuse is associated with worse periprocedural outcomes following PCI when controlling for key proxies of health status.

Percutaneous coronary intervention (PCI) in the context of heavily calcified coronary arteries can be challenging. Intravascular lithotripsy (IVL) has been suggested as an alternative to rotational atherectomy (RA). We report a case of stent under expansion, despite plaque modification using rotational atherectomy that was successfully managed with intravascular lithotripsy.

Transcatheter aortic valve replacement over the last few years has revolutionized the way severe aortic stenosis patients are being managed [1-4]. Randomized clinical trials commonly excluded bicuspid aortic valves and pure native severe aortic regurgitation [2,4]. We present a case with severe acute aortic regurgitation complicated by refractory pulmonary oedema successfully managed by transfemoral transcatheter aortic valve replacement using a Sapien 3 valve.

BACKGROUND: Aortic stenosis (AS) is a common valvular abnormality and transcatheter aortic valve implantation (TAVI) is being increasingly used to treat patients considered too high risk for conventional surgery. We aimed to assess the prevalence of comorbid conditions in patients undergoing TAVI using the Charlson Comorbidity Index (CCI) and to assess their impact on clinical and procedural outcomes. METHODS: We analysed 158 patients who underwent a TAVI at our institution between June 2009 and September 2015 to define their co-morbid burden as measured with CCI, and study its impact on procedural characteristics and mortality at 30 days. RESULTS: One hundred fifty-eight (158) patients with a mean age of 82±8years and a mean CCI score of 2.67 underwent a TAVI. Only 12/158 patients had a CCI of 0. The commonest cardiovascular comorbidities were previous myocardial infarction (24%), congestive heart failure (15%) and diabetes mellitus (23%) whilst the commonest non-cardiovascular comorbidities were renal disease (46%) and chronic obstructive pulmonary disease (COPD) (29%). After multivariable adjustment, CCI was not independently associated with adverse clinical outcomes. The addition of CCI to scoring systems such as Logistic EuroScore (LES) and Society of Thoracic Surgeons (STS) risk models improved the area under the curve from 0.75 (95%CI: 0.44-1.00) and 0.83 (95%CI: 0.64-1.00) to 0.78 (95%CI: 0.53-1.00) and 0.89 (95%CI: 0.78-1.00) respectively. CONCLUSIONS: The burden of comorbid conditions in patients undergoing TAVI is significant. The CCI score was not independently associated with a higher risk of death but can be useful in addition to LES and STS risk models in informing decision making on the selection of patients for TAVI.

AIM: TAVR in patients with bicuspid aortic valves (BAV) is more challenging compared to individuals with trileaflet aortic valves (TAV). BAV have been excluded from the large randomized clinical trials assessing transcatheter aortic valve replacements (TAVR) and has been considered as a relative contraindication to TAVR. To report the outcomes of TAVR in BAV and compare them to TAV in the National Inpatient Sample (NIS). METHODS AND RESULTS: TAVR procedures were identified between 2011 and 2014 in the NIS dataset. Endpoints assessed included in-hospital mortality, periprocedural complications, length of stay and cost. Of 40,604 identified TAVR procedures, 407 (1%) were BAV and the 40,197 (99%) were TAV. Patients with BAV were younger and had a lower comorbidity burden. In hospital mortality (4.89% vs 4.17%, OR: 1.71, 95%CI: 0.57-5.12, Pâ¯=â¯0.21), AMI (3.49% vs 3.58%, OR: 1.12, 95%CI: 0.36-3.54, Pâ¯=â¯0.85), stroke and TIA (2.49% vs 3.55%, OR: 0.75, 95%CI: 0.18-3.16, Pâ¯=â¯0.70), vascular complications (2.39% vs 5.58%, OR:0.47, 95%CI: 0.11-1.93, Pâ¯=â¯0.29), major bleeding (16.96% vs 23.50%, OR: 0.63, 95%CI: 0.34-1.17, Pâ¯=â¯0.15) and rates of permanent pacemaker (PPM) (9.88% vs 10.88%, OR: 1.19, 95%CI: 0.57-2.51, Pâ¯=â¯0.64) were similar in both cohorts. CONCLUSIONS: With multimodality imaging and further improvement in technology, our study demonstrates off-label TAVR should not be considered prohibitive and can be successfully performed for BAV with similar peri-procedural outcomes compared to those with TAV. However, there is a need for robust large prospective studies.

PURPOSE: Radial artery occlusion flowing cardiac catheterisation has been linked to flow reduction and prolonged compression. We investigate whether these factors can be optimised following transradial cardiac catheterisation by using an accelerated band removal protocol facilitated by a haemostasis promoting pad, in combination with a patent haemostasis technique. METHODS: In this single centre prospective study, 389 consecutive patients undergoing TRA for coronary angiography or angioplasty were randomised to two haemostasis protocols: use of a Helix™ compression device alone (HC) or in combination with a haemostatic pad (StatSeal® disc) and an accelerated haemostasis protocol (AC). A patent haemostasis technique was employed in both study arms. The primary efficacy endpoint was the time to haemostasis and the secondary safety outcome was access site related complications: re-bleeding, haematoma and radial artery patency assessed within 24â¯h using reverse Barbeau's Test (BT). RESULTS: Between May and Nov 2017, 191 patients were randomised to receive HC and 198 patients to AC. Compression time was significantly higher with HC as compared to AC (165.8⯱â¯63.1 versus 79.7⯱â¯41.2â¯min, pâ¯<â¯0.001). There were no significant differences in re-bleeding and RAO between groups (3.7% versus 5.6%, pâ¯=â¯0.37 and 6.3% versus 4.1%, pâ¯=â¯0.33) respectively. Incidence of haematoma was higher in AC group (4.7% versus 12.1%, pâ¯=â¯0.009). CONCLUSION: A reduction in radial artery compression time can be achieved by using Statseal in association with an accelerated haemostasis protocol without increasing the risk of access site bleeding and RAO. The combination of reduced compression time combined with maintained radial flow via patent haemostasis has the potential to reduce the risk of radial occlusion after transradial catheterisation.

OBJECTIVES: To investigate the association of the CharlsonComorbidity Index (CCI) with clinical outcomes after transcatheter aortic valve implantation (TAVI). BACKGROUND: Patients undergoing TAVI have high comorbid burden; however, there is limited evidence of its impact on clinical outcomes. METHODS: Data from 1887 patients from the UK, Canada, Spain, Switzerland and Italy were collected between 2007 and 2016. The association of CCI with 30-day mortality, Valve Academic Research Consortium-2 (VARC-2) composite early safety, long-term survival and length of stay (LoS) was calculated using logistic regression and Cox proportional hazard models, as a whole cohort and at a country level, through a two-stage individual participant data (IPD) random effect meta-analysis. RESULTS: Most (60%) of patients had a CCI ≥3. A weak correlation was found between the total CCI and four different preoperative risks scores (ρ=0.16 to 0.29), and approximately 50% of patients classed as low risk from four risk prediction models still presented with a CCI ≥3. Per-unit increases in total CCI were not associated with increased odds of 30-day mortality (OR 1.09, 95% CI 0.96 to 1.24) or VARC-2 early safety (OR 1.04, 95% CI 0.96 to 1.14) but were associated with increased hazard of long-term mortality (HR 1.10, 95% CI 1.05 to 1.16). The two-stage IPD meta-analysis indicated that CCI was not associated with LoS (HR 0.97, 95% CI 0.93 to 1.02). CONCLUSION: In this multicentre international study, patients undergoing TAVI had significant comorbid burden. We found a weak correlation between the CCI and well-established preoperative risks scores. The CCI had a moderate association with long-term mortality up to 5 years post-TAVI.

BACKGROUND: The radial artery is increasingly used for cardiac procedures, but is a relatively small vessel that is prone to spasm when instrumented. Intra-arterial nitroglycerine has been shown to reduce radial spasm but first requires arterial access. We investigated the effect of pre-procedure sublingual nitroglycerin (NTG) on the diameter of the radial artery in a large cohort of patients. METHODS: 305 subjects underwent ultrasound measurement of their radial and ulnar arteries in both arms before and after the administration of 800µg of sublingual NTG. The Allen's test was also performed in the subjects prior to and after NTG. RESULTS: Radial artery diameter in this Caucasian study group is larger than that reported for other populations. The administration of sublingual NTG significantly increased the size of the right radial artery from 2.88±0.36mm to 3.36±0.40mm in men and from 2.23±0.37 up to 2.74±0.36mm in women. There were also significant increases in left radial, right and left ulnar artery diameters in males and females with NTG. There was no significant effect of NTG on blood pressure. In all patients with an unfavourable Allen's test, retesting following sublingual NTG resulted in transition to a favourable Allen's. CONCLUSION: Caucasian populations have larger calibre radial arteries compared to other geographic areas. Sublingual NTG is effective at dilating the radial artery in both men and women. This may make radial artery puncture and cannulation less challenging and should be considered in all patients in the absence of contraindications. The results of Allen's testing are dynamic and its usefulness for screening prior to transradial access is undetermined.

BACKGROUND: The radial artery is increasingly adopted as the primary access site for cardiac catheterization because of patient preference, lower bleeding rates, cost effectiveness, and reduced risk of mortality in high-risk patient groups. Concerns have been expressed that operators/centers have become increasingly unfamiliar with transfemoral access. The aim of this study was to assess whether a change in access site practice toward transradial access nationally has led to worse outcomes in percutaneous coronary intervention procedures performed through the transfemoral access approach. METHODS AND RESULTS: Using the British Cardiovascular Intervention Society (BCIS) database, a retrospective analysis of 235 250 transfemoral access percutaneous coronary intervention procedures was undertaken in all 92 centers in England and Wales between 2007 and 2013. Recent femoral proportion and recent femoral volume were determined, and in-hospital vascular complications and 30-day mortality were evaluated. After case-mix adjustment, no independent association was observed between 30-day mortality for cases undertaken through the transfemoral access and center femoral proportion, the risk-adjusted odds ratio for recent femoral proportion was nonsignificant (odds ratio, 0.99; 95% confidence interval, 0.97-1.02; P=0.472 per 0.1 increase in proportion), and similarly recent femoral volume (per 100 procedures) was not found to be significant (odds ratio, 1.00; 95% confidence interval, 0.98-1.01; P=0.869). The in-hospital vascular complication rate was 1.0%, and this outcome was not significantly associated with recent femoral proportion after risk-adjustment (odds ratio, 0.97; 95% confidence interval, 0.94-1.00; P=0.060 per 0.1 increase in proportion). CONCLUSIONS: The outcome gains achieved by the national adoption of radial access are not associated with a loss of femoral proficiency, and centers should be encouraged to continue to adopt radial access as the default access site for percutaneous coronary intervention wherever possible in line with current best evidence.

BACKGROUND: While the uptake of transradial access site is growing, there are concerns about associated radial injury. We report a feasibility study of a technique that enables both 5Fr diagnostic and PCI cases to be undertaken without an arterial sheath using conventional diagnostic and guide catheters with a modified balloon assisted tracking (BAT) technique. METHODS: We performed a prospective single center pilot study to assess the feasibility and effectiveness of sheathless radial artery access and BAT to perform coronary angiography and angioplasty using conventional 5 Fr diagnostic and guide catheters. We assessed for successful acquisition of good quality angiogram, completion of the angioplasty and access site complications. RESULTS: 5 Fr sheathless cardiac catheterization was undertaken in diagnostic (55%) and PCI cases (45%, all indications) in 60 consecutive patients (mean age 62.8±11.4years) using conventional catheters. The procedure was successfully performed via the radial artery using a sheathless technique with BAT in 93.3% of patients. All patients had a patent radial artery following removal of the Helix device and there were no recorded access site complications. CONCLUSIONS: Trans-radial cardiac catheterisation for diagnostic and PCI cases using 5F Sheathless catheters (whose outer diameter is smaller than a 3Fr introducer sheath) with BAT appears feasible and allows both cardiac catheterization for diagnostic and PCI indications to be undertaken safely using conventional catheters through the radial route, with high success rates.

OBJECTIVES: Periprocedural bleedings, often related to vascular access site, represent an important drawback of percutaneous coronary procedures and are associated with worse outcomes. Radial access (RA) and, potentially, femoral access (FA) with vascular closure device (VCD) are useful strategies in order to mitigate periprocedural bleedings; nevertheless, their relative efficacy is largely undetermined. We aimed to perform a systematic review and meta-analysis of available studies comparing the efficacy of RA and FA with hemostasis by VCD (FA + VCD) on the reduction of access-site complications and/or periprocedural bleedings. METHODS: Published studies reporting outcomes on access-site complications and periprocedural bleedings were included in the analysis. Data were extracted by two independent reviewers; odds ratio (OR) and 95% confidence interval (CI) were calculated by random-effects model and were used as summary statistics. RESULTS: We included in the analysis 13 studies, of which 5 were randomized. Access-site complications were reported by 11 studies, amounting to 157,031 patients (77,713 in the RA group and 79,318 in the FA + VCD group), whereas periprocedural bleedings were reported by 12 studies, amounting to 600,196 patients (137,277 in the RA group and 462,919 in the FA + VCD group). RA was associated with a significant reduction in access-site complications (OR, 0.25; 95% CI ,0.21-0.31; P<.001) and periprocedural bleedings (OR, 0.40; 95% CI, 0.34-0.48; P<.001) as compared with FA + VCD; the results were consistent among randomized and observational studies. CONCLUSIONS: This meta-analysis shows that RA is superior to FA + VCD in the reduction of access-site complications and periprocedural bleedings.

A 78year old woman was admitted with an acute coronary syndrome. She underwent coronary angiography via the left radial artery which was complicated by a guide catheter induced radial artery perforation confirmed by extravasation of contrast into the forearm. We used balloon assisted tracking and guide catheter tamponade to complete the angioplasty procedure via the radial artery and successfully seal the radial artery perforation. We describe a series of 7 cases where this technique was used to both treat radial artery perforation and to complete the angioplasty via the radial approach.
