RESUMEN
Objectives: The aim of this postmarket clinical study was to assess the safety and efficacy of the latest generation polymer-free sirolimus-eluting stents (PF-SES) in an all-comers population comparing outcomes in stable coronary artery disease (CAD) versus acute coronary syndrome (ACS) in France. Background: The efficacy and safety of the first-generation PF-SES have already been demonstrated by randomized controlled trials and "all-comers" observational studies. Methods: For this all-comers observational, prospective, multicenter study, 1456 patients were recruited in 22 French centers. The primary endpoint was target lesion revascularization (TLR) rate at 12 months and secondary endpoints included major adverse cardiac events (MACE) and bleeding. Results: 895 patients had stable CAD and 561 had ACS. At 12 months, 2% of patients had a TLR, with similar rates between stable CAD and ACS (1.9% vs 2.2%, p = 0.7). The overall MACE rate was 5.2% with an expected higher rate in patients with ACS as compared to those with stable CAD (7.3% vs 3.9%, p = 0.007). The overall bleeding event rate was 4.5%, with similar rates in stable CAD as compared to ACS patients (3.8% vs 5.6%, p = 0.3). Dual antiplatelet therapy (DAPT) interruptions prior to the recommended duration occurred in 41.7% of patients with no increase in MACE rates as compared to patients who did not prematurely interrupt DAPT (3.9% vs 6.1%, p = 0.073). Conclusions: The latest generation PF-SES is associated with low clinical event rates in these all-comers patients. There was a high rate of prematurely terminated DAPT, without any effect on MACE at 12 months. This trial is registered with NCT03809715.

BACKGROUND: Branched-chain amino acid (BCAA) supplementation has been linked with favorable outcomes in patients undergoing surgical or palliative treatments for hepatocellular carcinoma (HCC). To date, there has been no systematic review investigating the value of BCAA supplementation in HCC patients undergoing locoregional therapies. MATERIALS AND METHODS: A systematic search of the literature was performed across five databases/registries using a detailed search algorithm according to the preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement. The search was conducted on March 23, 2022. RESULTS: Sixteen studies with a total of 1594 patients were analyzed. Most patients were male (64.6%) with a mean age of 68.2 ± 4.1 years, Child-Pugh score A (67.9%) and stage II disease (40.0%). Locoregional therapy consisted of radiofrequency ablation, transarterial chemoembolization or hepatic artery infusion chemotherapy. BCAA supplementation was in the form of BCAA granules or BCAA-enriched nutrient. Most studies reported improved albumin levels, non-protein respiratory quotient and quality of life in the BCAA group. Results pertaining to other outcomes including overall survival, recurrence rate, and Child-Pugh score were variable. Meta-analysis showed significantly higher levels of post-treatment serum albumin in the BCAA group (SMD = 0.54, 95% CI 0.20-0.87) but no significant differences in mortality rate (RR = 0.81, 95% CI: 0.65-1.02) and AST (SMD = -0.13, 95% CI: -0.43-0.18). CONCLUSION: BCAA supplementation is associated with higher post-treatment albumin levels. There are currently not sufficient data to support additional benefits. Further studies are needed to elucidate their value.
RESUMEN
BACKGROUND: Optimizing patient exposure in interventional cardiology is key to avoid skin injuries. PURPOSE: To establish predictive models of peak skin dose (PSD) during percutaneous coronary intervention (PCI), chronic total occlusion percutaneous coronary intervention (CTO), and transcatheter aortic valve implantation (TAVI) procedures. MATERIAL AND METHODS: A total of 534 PCI, 219 CTO, and 209 TAVI were collected from 12 hospitals in eight European countries. Independent associations between PSD and clinical and technical dose determinants were examined for those procedures using multivariate statistical analysis. A priori and a posteriori predictive models were built using stepwise multiple linear regressions. A fourfold cross-validation was performed, and models' performance was evaluated using the root mean square error (RMSE), mean absolute percentage error (MAPE), coefficient of determination (R²), and linear correlation coefficient (r). RESULTS: Multivariate analysis proved technical parameters to overweight clinical complexity indices with PSD mainly affected by fluoroscopy time, tube voltage, tube current, distance to detector, and tube angulation for PCI. For CTO, these were body mass index, tube voltage, and fluoroscopy contribution. For TAVI, these parameters were sex, fluoroscopy time, tube voltage, and cine acquisitions. When benchmarking the predictive models, the correlation coefficients were r = 0.45 for the a priori model and r = 0.89 for the a posteriori model for PCI. These were 0.44 and 0.67, respectively, for the CTO a priori and a posteriori models, and 0.58 and 0.74, respectively, for the TAVI a priori and a posteriori models. CONCLUSION: A priori predictive models can help operators estimate the PSD before performing the intervention while a posteriori models are more accurate estimates and can be useful in the absence of skin dose mapping solutions.

BACKGROUND: Patients can be exposed to high skin doses during complex interventional cardiology (IC) procedures. PURPOSE: To identify which clinical and technical parameters affect patient exposure and peak skin dose (PSD) and to establish dose reference levels (DRL) per clinical complexity level in IC procedures. MATERIAL AND METHODS: Validation and Estimation of Radiation skin Dose in Interventional Cardiology (VERIDIC) project analyzed prospectively collected patient data from eight European countries and 12 hospitals where percutaneous coronary intervention (PCI), chronic total occlusion PCI (CTO), and transcatheter aortic valve implantation (TAVI) procedures were performed. A total of 62 clinical complexity parameters and 31 technical parameters were collected, univariate regressions were performed to identify those parameters affecting patient exposure and define DRL accordingly. RESULTS: Patient exposure as well as clinical and technical parameters were collected for a total of 534 PCI, 219 CTO, and 209 TAVI. For PCI procedures, body mass index (BMI), number of stents ≥2, and total stent length >28â mm were the most prominent clinical parameters, which increased the PSD value. For CTO, these were total stent length >57â mm, BMI, and previous anterograde or retrograde technique that failed in the same session. For TAVI, these were male sex, BMI, and number of diseased vessels. DRL values for Kerma-area product (PKA), air kerma at patient entrance reference point (Ka,r), fluoroscopy time (FT), and PSD were stratified, respectively, for 14 clinical parameters in PCI, 10 in CTO, and four in TAVI. CONCLUSION: Prior knowledge of the key factors influencing the PSD will help optimize patient radiation protection in IC.

BACKGROUND: Since majority of sudden cardiac arrest (SCA) victims die in the intensive care unit (ICU), early etiologic investigations may improve understanding of SCA and targeted prevention. METHODS: In this prospective, population-based registry all SCA admitted alive across the 48 hospitals of the Paris area were enrolled. We investigated the extent of early etiologic work-up among young SCD cases (<45 years) eventually dying within the ICU. RESULTS: From May 2011 to May 2018, 4,314 SCA patients were admitted alive. Among them, 3,044 died in ICU, including 484 (15.9%) young patients. SCA etiology was established in 233 (48.1%) and remained unexplained in 251 (51.9%). Among unexplained (compared to explained) cases, coronary angiography (17.9 vs. 49.4%, P < 0.001), computed tomography scan (24.7 vs. 46.8%, P < 0.001) and trans-thoracic echocardiography (31.1 vs. 56.7%, P < 0.001) were less frequently performed. Only 22 (8.8%) patients with unexplained SCD underwent all three investigations. SCDs with unexplained status decreased significantly over the 7 years of the study period (from 62.9 to 35.2%, P = 0.005). While specialized TTE and CT scan performances have increased significantly, performance of early coronary angiography did not change. Autopsy, genetic analysis and family screening were performed in only 48 (9.9%), 5 (1.0%) and 14 cases (2.9%) respectively. CONCLUSIONS: More than half of young SCD dying in ICU remained etiologically unexplained; this was associated with a lack of early investigations. Improving early diagnosis may enhance both SCA understanding and prevention, including for relatives. Failure to identify familial conditions may result in other preventable deaths within these families.

Background: Aside from the culprit plaque, the presence of vulnerable plaques in patients with acute coronary syndrome (ACS) may be associated with future cardiac events. A link between calcification and plaque rupture has been previously described. Aim: To assess whether analysis of the calcium component of coronary plaques using CT angiography, coronary computed tomographic angiography (CCTA) can help to detect additional vulnerable plaques in patients with non-ST elevation myocardial infarction (NSTEMI). Materials And Methods: Cross sectional study of consecutive patients referred for NSTEMI from 30 July to 30 August 2018 with CCTA performed before coronary angiography with systematic optical coherence tomography (OCT) analysis of all coronary arteries within 24 h of clinical onset of NSTEMI. Three types of plaques were defined: culprit plaques defined by angiography (vulnerable culprit plaques-VCP) - plaques with a fibrous cap thickness < 65 microns or thrombus in OCT (vulnerable non-culprit plaque-VNCP) - plaques with a fibrous cap thickness ≥ 65 microns in OCT (stable plaque-SP). Results: A total of 134 calcified plaques were identified in 29 patients (73% male, 59 ± 14 years) with 29(22%) VCP, 28(21%) VNCP and 77(57%) SP. Using CCTA analysis of the calcium component, factors associated with vulnerable plaques were longer calcification length, larger calcification volume, lower calcium mass, higher Agatston score plaque-specific (ASp), presence of spotty calcifications and an intimal position in the wall. In multivariate analysis, ASp, calcification length and spotty calcifications were independently associated to vulnerable plaques. There was no difference between VCP and VNCP. Conclusions: CCTA analysis of calcium component of the plaque could help to identify additional vulnerable plaques in NSTEMI patients.
RESUMEN
The first year of the coronavirus disease 2019 (COVID-19) pandemic has been a year of unprecedented changes, scientific breakthroughs, and controversies. The radiology community has not been spared from the challenges imposed on global healthcare systems. Radiology has played a crucial part in tackling this pandemic, either by demonstrating the manifestations of the virus and guiding patient management, or by safely handling the patients and mitigating transmission within the hospital. Major modifications involving all aspects of daily radiology practice have occurred as a result of the pandemic, including workflow alterations, volume reductions, and strict infection control strategies. Despite the ongoing challenges, considerable knowledge has been gained that will guide future innovations. The aim of this review is to provide the latest evidence on the role of imaging in the diagnosis of the multifaceted manifestations of COVID-19, and to discuss the implications of the pandemic on radiology departments globally, including infection control strategies and delays in cancer screening. Lastly, the promising contribution of artificial intelligence in the COVID-19 pandemic is explored.
RESUMEN
BACKGROUND: Thousands of web searches are performed related to transarterial chemoembolization (TACE), given its palliative role in the treatment of liver cancer. OBJECTIVE: This study aims to assess the reliability, quality, completeness, readability, understandability, and actionability of websites that provide information on TACE for patients. METHODS: The five most popular keywords pertaining to TACE were searched on Google, Yahoo, and Bing. General website characteristics and the presence of Health On the Net Foundation code certification were documented. Website assessment was performed using the following scores: DISCERN, Journal of the American Medical Association, Flesch-Kincaid Grade Level, Flesch Reading Ease Score, and the Patient Education Materials Assessment Tool. A novel TACE content score was generated to evaluate website completeness. RESULTS: The search yielded 3750 websites. In total, 81 website entities belonging to 78 website domains met the inclusion criteria. A medical disclaimer was not provided on 28% (22/78) of website domains. Health On the Net code certification was present on 12% (9/78) of website domains. Authorship was absent on 88% (71/81) of websites, and sources were absent on 83% (67/81) of websites. The date of publication or of the last update was not listed on 58% (47/81) of websites. The median DISCERN score was 47.0 (IQR 40.5-54.0). The median TACE content score was 35 (IQR 27-43). The median readability grade level was in the 11th grade. Overall, 61% (49/81) and 16% (13/81) of websites were deemed understandable and actionable, respectively. Not-for-profit websites fared significantly better on the Journal of the American Medical Association, DISCERN, and TACE content scores. CONCLUSIONS: The content referring to TACE that is currently available on the web is unreliable, incomplete, difficult to read, understandable but not actionable, and characterized by low overall quality. Websites need to revise their content to optimally educate consumers and support shared decision-making.

RESUMEN
BACKGROUND: No consensus currently exists regarding the optimal approach for peritoneal dialysis catheter placement. We aimed to compare the outcomes of percutaneous and surgical peritoneal dialysis catheter placement. METHODS: A systematic review of the literature was performed using the MEDLINE, Cochrane Library, and Scopus databases (end-of-search date: August 29th, 2020). We included studies comparing percutaneous (blind, under fluoroscopic/ultrasound guidance, and "half-perc") and surgical peritoneal dialysis catheter placement (open and laparoscopic) in terms of their infectious complications (peritonitis, tunnel/exit-site infections), mechanical complications (leakage, inflow/outflow obstruction, migration, hemorrhage, hernia, bowel perforation) and long-term outcomes (malfunction, removal, replacement, surgery required, and mortality). RESULTS: Thirty-four studies were identified, including thirty-two observational studies (twenty-six retrospective and six prospective) and two randomized controlled trials. Percutaneous placement was associated with significantly lower rates of tunnel/exit-site infection [relative risk (RR) 0.72, 95% confidence interval (CI) 0.56-0.91], catheter migration (RR 0.68, 95% CI 0.49, 0.95), and catheter removal (RR 0.73, 95% CI 0.60-0.88). The 2-week and 4-week rates of early tunnel/exit-site infection were also lower in the percutaneous group (RR 0.45, 95% CI 0.22-0.93 and RR 0.41, 95% CI 0.27-0.63, respectively). No statistically significant difference was observed regarding other outcomes, including catheter survival and mechanical complications. CONCLUSION: Overall, the quality of published literature on the field of peritoneal dialysis catheter placement is poor, with a small percentage of studies being randomized clinical trials. Percutaneous peritoneal dialysis catheter placement is a safe procedure and may result in fewer complications, such as tunnel/exit-site infections, and catheter migration, compared to surgical placement.

BACKGROUND: Liver transplantation (LT) has gained interest in the treatment of unresectable colorectal liver metastases (CRLM) over the last two decades. Despite the initial poor outcomes, recent reports from countries with graft abundance have provided further insights in the potential of LT as a treatment for unresectable CRLM. METHODS: A systematic literature search was conducted in the MEDLINE (PubMed), Embase, Scopus, Cochrane Library, Google Scholar, Virtual Health Library, Clinicaltrials.gov, and Web of Science databases (end-of-search date: January 27th, 2020) to identify relevant studies. Pooled overall and recurrence-free survival analysis at 6 months, 1, 2, 3, and 5 years was conducted with the Kaplan-Meier (Product Limit) method. RESULTS: Eighteen studies comprising 110 patients were included. The population consisted of 59.8% males with a mean age of 52.3 ± 9.3 years. CRLM diagnosis was synchronous in 83%, while 99% received chemotherapy, and 39% received liver resection prior to LT. The mean time from primary tumor resection to LT was 39.5 ± 32.5 months, the mean post-LT follow-up was 32.1 ± 22.2 months, and the mean time to recurrence was 15.0 ± 11.3 months. The pooled 6-month, 1-, 2-, 3-, and 5-year overall survival rates were 95.7% (95%CI: 89.1%-98.4%), 88.1% (95%CI: 79.6%-93.2%), 74.6% (95%CI: 64.2%-82.3%), 58.4% (95%CI: 47.2%-62.0%), and 50.5% (95%CI: 39.0%-61.0%), respectively. The pooled 6-months, 1-, 2-, 3-, and 5-year recurrence-free survival rates were 77.2% (95%CI: 67.2%-84.5%), 59.9% (95%CI: 49.0%-69.2%), 42.4% (95%CI: 31.8%-52.6%), 30.7% (95%CI: 20.9%-41.1%), and 25.6% (95%CI: 16.2%-36.0%), respectively. CONCLUSION: LT should be considered in patients with unresectable liver-only CRLM under strict selection criteria and only under well-designed research protocols. Ongoing studies are expected to further elucidate the indications and prognosis of patients undergoing LT for unresectable CRLM.

BACKGROUND: Conflicting data exist regarding the benefit of urgent coronary angiogram and percutaneous coronary intervention (PCI) after sudden cardiac arrest, particularly in the absence of ST-segment elevation. We hypothesized that the type of lesions treated (stable versus unstable) influences the benefit derived from PCI. METHODS: Data were taken between May 2011 and 2014 from a prospective registry enrolling all sudden cardiac arrest in Paris and suburbs (6.7 million inhabitants). Patients undergoing emergent coronary angiogram were included. Decision to perform PCI was left to the discretion of local teams. We assessed the impact of emergent PCI on survival at discharge according to whether the treated lesion was angiographically unstable or stable, and we investigated the predictive factors for unstable coronary lesions. RESULTS: Among 9265 sudden cardiac arrests occurring during the study period, 1078 underwent emergent coronary angiogram (median age: 59.6 years, 78.3% males): 463 (42.9%) had an unstable lesion, 253 (23.5%) only stable lesions, and 362 (33.6%) no significant lesions. Emergent PCI was performed in 478 patients (91.4% of unstable and 21.7% of stable lesions). At discharge, PCI of unstable lesions was associated with twice-higher survival rate compared with untreated unstable lesions (47.9% versus 25.6%, P=0.013), while stable lesions PCI did not improve survival (25.5% versus 26.3%, P=1.00). After adjustment, PCI of unstable coronary lesions was independently associated with improved survival (odds ratio, 2.09 [95% CI, 1.42-3.09], P<0.001), contrary to PCI of stable lesions (odds ratio, 0.92 [95% CI. 0.44-1.87], P=0.824). Angina, initial shockable rhythm, ST-segment elevation, and absence of known coronary artery disease were independent predictors of unstable lesions. CONCLUSIONS: Emergent PCI of unstable lesions is associated with improved survival after sudden cardiac arrest, contrary to PCI of stable lesions. Accordingly, early PCI should only be performed in patients with unstable lesions. Four factors (chest pain, ST-elevation, absence of coronary artery disease history, and shockable initial rhythm) could help identify patients with unstable lesions who would, therefore, benefit from emergent coronary angiogram.

AIM: Coronary angiogram (CA) may be useful after resuscitated out-of-hospital cardiac arrest (OHCA), but data regarding its benefit in patients with non-shockable initial rhythm without ST-segment elevation is scarce. We aimed to evaluate the prevalence of acute coronary syndrome (ACS) and survival in OHCA patients with non-shockable initial rhythm without ST-segment elevation and compare them to patients with shockable initial rhythm without ST-segment elevation. METHODS: Retrospective single-centre study approved by the ethics committee of our institution, including adults successfully resuscitated from OHCA of presumed cardiac cause, undergoing routine CA on admission. Baseline characteristics, angiographic data including presence of ACS and survival were compared between patients with non-shockable and shockable initial rhythm focusing on patients without ST-segment elevation. RESULTS: Among 517 patients included between 2002 and 2018, 311 had no ST-elevation, of whom 179 had non-shockable and 132 shockable initial rhythm. Compared with shockable initial rhythm patients without ST-elevation, non-shockable initial rhythm patients without ST-elevation had longer no-flow duration, 5 (1-10) versus 2 (0-8) min, pâ¯=â¯0.024, more frequent shock requiring vasopressors, 72% versus 47% pâ¯<â¯0.0001, a lower prevalence of ACS, 2 (1%), versus 29 (22%), pâ¯<â¯0.001 and higher mortality, 85% versus 39% (pâ¯<â¯0.0001). Among ACS patients, none survived in the non-shockable without ST-elevation group, while 20 (69%) survived in the shockable rhythm without ST-elevation group. CONCLUSIONS: Prevalence of ACS in patients without ST-segment elevation and non-shockable initial rhythm is extremely low, and survival extremely poor, therefore routine emergency CA does not seem beneficial in these patients.

Importance: Approximately one-third of patients considered for coronary revascularization have diabetes, which is a major determinant of clinical outcomes, often influencing the choice of the revascularization strategy. The usefulness of fractional flow reserve (FFR) to guide treatment in this population is understudied and has been questioned. Objective: To evaluate the usefulness and rate of major adverse cardiovascular events (MACE) of integrating FFR in management decisions for patients with diabetes who undergo coronary angiography. Design, Setting, and Participants: This cross-sectional study used data from the PRIME-FFR study derived from the merger of the POST-IT study (Portuguese Study on the Evaluation of FFR-Guided Treatment of Coronary Disease [March 2012-November 2013]) and R3F study (French Study of FFR Integrated Multicenter Registries Implementation of FFR in Routine Practice [October 2008-June 2010]), 2 prospective multicenter registries that shared a common design. A population of all-comers for whom angiography disclosed ambiguous lesions was analyzed for rates, patterns, and outcomes associated with management reclassification, including revascularization deferral, in patients with vs without diabetes. Data analysis was performed from June to August 2018. Main Outcomes and Measures: Death from any cause, myocardial infarction, or unplanned revascularization (MACE) at 1 year. Results: Among 1983 patients (1503 [77%] male; mean [SD] age, 65 [10] years), 701 had diabetes, and FFR was performed for 1.4 lesions per patient (58.2% of lesions in the left anterior descending artery; mean [SD] stenosis, 56% [11%]; mean [SD] FFR, 0.81 [0.01]). Reclassification by FFR was high and similar in patients with and without diabetes (41.2% vs 37.5%, P = .13), but reclassification from medical treatment to revascularization was more frequent in the former (142 of 342 [41.5%] vs 230 of 730 [31.5%], P = .001). There was no statistical difference between the 1-year rates of MACE in reclassified (9.7%) and nonreclassified patients (12.0%) (P = .37). Among patients with diabetes, FFR-based deferral identified patients with a lower risk of MACE at 12 months (25 of 296 [8.4%]) compared with those undergoing revascularization (47 of 257 [13.1%]) (P = .04), and the rate was of the same magnitude of the observed rate among deferred patients without diabetes (7.9%, P = .87). Status of insulin treatment had no association with outcomes. Patients (6.6% of the population) in whom FFR was disregarded had the highest MACE rates regardless of diabetes status. Conclusions and Relevance: Routine integration of FFR for the management of coronary artery disease in patients with diabetes may be associated with a high rate of treatment reclassification. Management strategies guided by FFR, including revascularization deferral, may be useful for patients with diabetes.

AIM: Coronary artery disease (CAD) has recently been emphasized as a major cause of sudden cardiac arrest (SCA) in young adults. We aim to assess the rate of immediate coronary angiography performance in young patients resuscitated from SCA. METHODS: From May 2011 to May 2017, all cases of out-of-hospital SCA aged 18-40 years alive at hospital admission were prospectively included in 48 hospitals of the Great Paris area. Cardiovascular causes of SCA were centrally adjudicated, and management including immediate coronary angiography performance was assessed. RESULTS: Out of 3579 SCA admitted alive, 409 (11.4%) patients were under 40 years of age (32.3 ± 6.2 years, 69.7% males), with 244 patients having a definite cause identified. Among those, CAD accounted for 72 (29.5%) cases, of which 64 (88.9%) were acute coronary syndromes. The rate of immediate coronary angiography was only 41.7% compared to 65.1% among those ≥40-years (P < 0.001). During the study period, while the rate of immediate coronary angiography increased from 60.5% to 70.3% (P < 0.001) in patients aged ≥40 years, the rate in patients aged less than 40 years remained stable (43.5% to 45.3%, P = 0.795). Patients younger than 40 years were significantly less likely to undergo immediate coronary angiography (OR = 0.34, 95% CI: 0.25-0.47), although early angiography was associated with survival at hospital discharge (OR = 2.68, 95% CI: 1.21-6.00). CONCLUSION: CAD is the first cause of SCA in young adults aged less than 40 years. The observed low rates of immediate coronary angiography suggest a missed opportunity for early intervention.

AIMS: Out-of-hospital cardiac arrest (OHCA) without return of spontaneous circulation (ROSC) despite conventional resuscitation is common and has poor outcomes. Adding extracorporeal membrane oxygenation (ECMO) to cardiopulmonary resuscitation (extracorporeal-CPR) is increasingly used in an attempt to improve outcomes. METHODS AND RESULTS: We analysed a prospective registry of 13 191 OHCAs in the Paris region from May 2011 to January 2018. We compared survival at hospital discharge with and without extracorporeal-CPR and identified factors associated with survival in patients given extracorporeal-CPR. Survival was 8% in 525 patients given extracorporeal-CPR and 9% in 12 666 patients given conventional-CPR (P = 0.91). By adjusted multivariate analysis, extracorporeal-CPR was not associated with hospital survival [odds ratio (OR), 1.3; 95% confidence interval (95% CI), 0.8-2.1; P = 0.24]. By conditional logistic regression with matching on a propensity score (including age, sex, occurrence at home, bystander CPR, initial rhythm, collapse-to-CPR time, duration of resuscitation, and ROSC), similar results were found (OR, 0.8; 95% CI, 0.5-1.3; P = 0.41). In the extracorporeal-CPR group, factors associated with hospital survival were initial shockable rhythm (OR, 3.9; 95% CI, 1.5-10.3; P = 0.005), transient ROSC before ECMO (OR, 2.3; 95% CI, 1.1-4.7; P = 0.03), and prehospital ECMO implantation (OR, 2.9; 95% CI, 1.5-5.9; P = 0.002). CONCLUSIONS: In a population-based registry, 4% of OHCAs were treated with extracorporeal-CPR, which was not associated with increased hospital survival. Early ECMO implantation may improve outcomes. The initial rhythm and ROSC may help select patients for extracorporeal-CPR.
