Outcomes and Comparative Analysis of the Initial Results of Standard Balloon Angioplasty Versus Drug-Coated Balloons Alone Versus in Association With Laser-Excimer Atherectomy in the Treatment of Femoropopliteal Artery In-Stent Restenosis (INTACT).

BACKGROUND: Despite improved patency with newer-generation nitinol stents, one-half of patients will require secondary interventions for in-stent restenosis (ISR). The best treatment strategy remains unclear. This study aimed to compare drug-coated balloons (DCBs) used alone or in association with excimer laser atherectomy (ELA) to simple percutaneous transluminal angioplasty (PTA) in the treatment of femoropopliteal-ISR. METHODS: The INTACT trial is a multicenter, prospective, triple-arm randomized trial conducted across 14 centers from December 2015 to November 2019. Patients Rutherford Class 2-5 with ISR≥70% were followed-up for 18 months. The primary efficacy endpoint was recurrent ISR>70% by duplex ultrasound analysis. The primary safety endpoint was major adverse events (MAEs) defined as death, major amputation, or target lesion revascularization (TLR). RESULTS: Around 134 subjects were randomized to PTA alone (n=41), PTA+DCB (n=43) or PTA+ELA+DCB (n=50). Procedural success was similar (p=.74), as was clinical success (p=.17). The number of recurrent ISR>70% decreased after PTA+ELA+DCB (30.0%; p=.04) and PTA+DCB (30.2%; p=.05) compared to PTA alone (51.2%). Primary patency was higher after PTA+ELA+DCB (log-rank p=.04) and PTA+DCB (log-rank p=.02) compared to PTA alone at 12 months (78.7% and 70.4% vs 61.5%) and 18 months (61.6% and 67.7% vs 37.3%). Freedom from MAEs was lower after PTA+DCB (27.9%) compared to PTA alone (53.7%; p=.02) but did not differ with PTA+ELA+DCB (40.0%). It was primarily driven by TLR; 2 major amputations occurred after PTA+ELA+DCB (4.0%; p=.18). CONCLUSION: This independent study demonstrated a decrease in recurrent ISR>70% and increase in primary patency up to 18 months after PTA+ELA+DCB and PTA+DCB compared to PTA alone in the treatment of FP-ISR. It did not show an increase in MAEs but could have lacked power. CLINICAL IMPACT: This multicenter, prospective, triple-arm randomized, controlled trial focuses on the results of adjunctive therapies, such as excimer laser atherectomy (ELA) and/or drug-coated balloons (DCBs) in the treatment of in-stent restenosis (ISR) in femoropopliteal lesions in 134 patients. It has the originality of being an independent study funded by a grant from the French Ministry of Health. This study confirms a significant decrease in recurrent ISR >70% and increase in primary patency up to 18 months after the use of ELA+DCB and DCBs compared to simple percutaneous transluminal angioplasty in the treatment of femoropopliteal ISR without an increase in major adverse events.

Clinical effects of permanent pacemaker implantation after transcatheter aortic valve implantation: Insights from the nationwide FRANCE-TAVI registry.

BACKGROUND: The influence of permanent pacemaker implantation upon outcomes after transcatheter aortic valve implantation (TAVI) remains controversial. AIMS: To evaluate the impact of permanent pacemaker implantation after TAVI on short- and long-term mortality, and on the risk of hospitalization for heart failure. METHODS: Data from the large FRANCE-TAVI registry, linked to the French national health single-payer claims database, were analysed to compare 30-day and long-term mortality rates and hospitalization for heart failure rates among patients with versus without permanent pacemaker implantation after TAVI. Multivariable regressions were performed to adjust for confounders. RESULTS: A total of 36,549 patients (mean age 82.6years; 51.6% female) who underwent TAVI from 2013 to 2019 were included in the present analysis. Among them, 6999 (19.1%) received permanent pacemaker implantation during the index hospitalization, whereas 232 (0.6%) underwent permanent pacemaker implantation between hospital discharge and 30days after TAVI, at a median of 11 (interquartile range: 7-18) days. In-hospital permanent pacemaker implantation was not associated with an increased risk of death between discharge and 30days (adjusted odds ratio: 0.91, 95% confidence interval: 0.64-1.29). At 5years, the incidence of all-cause death was higher among patients with versus without permanent pacemaker implantation within 30days of the procedure (adjusted hazard ratio: 1.13, 95% confidence interval: 1.07-1.19). Permanent pacemaker implantation within 30days of TAVI was also associated with a higher 5-year rate of hospitalization for heart failure (adjusted subhazard ratio: 1.17, 95% confidence interval: 1.11-1.23). CONCLUSIONS: Permanent pacemaker implantation after TAVI is associated with an increased risk of long-term hospitalization for heart failure and all-cause mortality. Further research to mitigate the risk of postprocedural permanent pacemaker implantation is needed as TAVI indications expand to lower-risk patients.

The France PCI registry: Design, methodology and key findings.

BACKGROUND: Obstructive coronary artery disease is the main cause of death worldwide. By tracking events and gaining feedback on patient management, the most relevant information is provided to public health services to further improve prognosis. AIMS: To create an inclusive and accurate registry of all percutaneous coronary intervention (PCI) procedures performed in France, to assess and improve the quality of care and create research incentives. Also, to describe the methodology of this French national registry of interventional cardiology, and present early key findings. METHODS: The France PCI registry is a multicentre observational registry that includes consecutive patients undergoing coronary angiography and/or PCI. The registry was set up to provide online data analysis and structured reports of PCI activity, including process of care measures and assessment of risk-adjusted outcomes in all French PCI centres that are willing to participate. More than 150 baseline data items, describing demographic status, PCI indications and techniques, and in-hospital and 1-year outcomes, are captured into local reporting software by medical doctors and local research technicians, with subsequent encryption and internet transfer to central data servers. Annual activity reports and scoring tools available on the France PCI website enable users to benchmark and improve clinical practices. External validation and consistency assessments are performed, with feedback of data completeness to centres. RESULTS: Between 01 January 2014 and 31 December 2022, participating centres increased from six to 47, and collected 364,770 invasive coronary angiograms and 176,030 PCIs, including 54,049 non-ST-segment elevation myocardial infarction cases and 31,631 ST-segment elevation myocardial infarction cases. Fifteen studies stemming from the France PCI registry have already been published. CONCLUSIONS: This fully electronic, daily updated, high-quality, low-cost, national registry is sustainable, and is now expanding. Merging with medicoeconomic databases and nested randomized scientific studies are ongoing steps to expand its scientific potential.

Prevalence, Management and Outcomes of Percutaneous Coronary Intervention for Coronary In-Stent Restenosis: Insights From the France PCI Registry.

BACKGROUND: Despite the evolution of stent technology, there is a non-negligible risk of in-stent restenosis (ISR) after Percutaneous coronary intervention (PCI). Large-scale registry data on the prevalence and clinical management of ISR is lacking. METHODS: The aim was to describe the epidemiology and management of patients with ≥1 ISR lesions treated with PCI (ISR PCI). Data on characteristics, management and clinical outcomes were analyzed for patients undergoing ISR PCI in the France-PCI all-comers registry. RESULTS: Between January 2014 and December 2018, 31,892 lesions were treated in 22,592 patients, 7.3 % of whom underwent ISR PCI. Patients undergoing ISR PCI were older (68.5 vs 67.8; p < 0.001), and more likely to have diabetes (32.7 % vs 25.4 %, p < 0.001), chronic coronary syndrome or multivessel disease. ISR PCI concerned drug eluting stents (DES) ISR in 48.8 % of cases. Patients with ISR lesions were more frequently treated with DES than drug eluting balloon or balloon angioplasty (74.2 %, 11.6 % and 12.9 %, respectively). Intravascular imaging was rarely used. At 1 year, patients with ISR had higher target lesion revascularization rates (4.3 % vs. 1.6 %; HR 2.24 [1.64-3.06]; p < 0.001). CONCLUSIONS: In a large all-comers registry, ISR PCI was not infrequent and associated with worse prognosis than non-ISR PCI. Further studies and technical improvements are warranted to improve the outcomes of ISR PCI.

Clinical outcomes after unprotected left main coronary artery occlusion: A retrospective multicentre cohort analysis.

AIMS: Unprotected left main coronary artery (ULMCA) occlusion is a rare and disastrous condition with scarce data on presentation and outcomes. Herein, we report data on patients presenting with acute coronary syndrome due to ULMCA occlusion at four different institutions. METHODS: This is an international multicentre observational study. Baseline characteristics were retro- and prospectively collected. Clinical follow-up was prospective. The primary outcome was in-hospital death. Patients surviving the index hospitalization were compared with nonsurvivors to find predictors of survival. RESULTS: The study population consisted of 55 patients. Eight patients (15%) died in the cath lab, and 23 (42%) died in hospital. Three (6%) deaths were noncardiac and due to major bleeding. Thirty-two (58%) patients survived the index hospitalization and were discharged. These patients were followed for a median of 17.5 months during which three cardiac deaths occurred. Repeat revascularization was performed in 25% (n = 8). Overall mortality at maximum follow-up was 47% (n = 26). The only significant predictor for hospital survival was left ventricular ejection fraction (odds ratio [OR]: 1.10 (per 1 point increase); 95% confidence interval [CI]: 1.02-1.19; p = 0.02). CONCLUSION: ULMCA occlusion carries a high short-term mortality. Patients who survive index hospitalization have similar mortality rates as compared with other st elevation myocardial infarction patients.

Long-Term Prognosis Value of Paravalvular Leak and Patient-Prosthesis Mismatch following Transcatheter Aortic Valve Implantation: Insight from the France-TAVI Registry.

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is the preferred treatment for symptomatic severe aortic stenosis (AS) in a majority of patients across all surgical risks. PATIENTS AND METHODS: Paravalvular leak (PVL) and patient-prosthesis mismatch (PPM) are two frequent complications of TAVI. Therefore, based on the large France-TAVI registry, we planned to report the incidence of both complications following TAVI, evaluate their respective risk factors, and study their respective impacts on long-term clinical outcomes, including mortality. RESULTS: We identified 47,494 patients in the database who underwent a TAVI in France between 1 January 2010 and 31 December 2019. Within this population, 17,742 patients had information regarding PPM status (5138 with moderate-to-severe PPM, 29.0%) and 20,878 had information regarding PVL (4056 with PVL ≥ 2, 19.4%). After adjustment, the risk factors for PVL ≥ 2 were a lower body mass index (BMI), a high baseline mean aortic gradient, a higher body surface area, a lower ejection fraction, a smaller diameter of TAVI, and a self-expandable TAVI device, while for moderate-to-severe PPM we identified a younger age, a lower BMI, a larger body surface area, a low aortic annulus area, a low ejection fraction, and a smaller diameter TAVI device (OR 0.85; 95% CI, 0.83-0.86) as predictors. At 6.5 years, PVL ≥ 2 was an independent predictor of mortality and was associated with higher mortality risk. PPM was not associated with increased risk of mortality. CONCLUSIONS: Our analysis from the France-TAVI registry showed that both moderate-to-severe PPM and PVL ≥ 2 continue to be frequently observed after the TAVI procedure. Different risk factors, mostly related to the patient's anatomy and TAVI device selection, for both complications have been identified. Only PVL ≥ 2 was associated with higher mortality during follow-up.

Early survival after acute myocardial infarction with ST-segment elevation: What could be improved? Insights from France PCI French registry.

Early mortality post-ST-segment elevation myocardial infarction (STEMI) in France remains high. The multicentre France Percutaneous Coronary Intervention Registry includes every patient undergoing coronary angiography in France. We analyzed the prevalence and impact of unmodifiable and modifiable risk factors on 30-day survival in patients experiencing STEMI. Patients admitted for STEMI between 01/2014 and 12/2016 were included in the analysis. Patients with nonobstructive coronary artery disease, with cardiogenic shock or cardiac arrest without STEMI, were excluded. Prehospital, clinical and procedural data were collected prospectively by the cardiologist in the cath lab using medical reporting software. Information on outcomes, including mortality, was obtained by a dedicated research technician by phone calls or from medical records. Marginal Cox proportional hazards regression was used to test the predictive value for survival at 30 days in a multivariable analysis. Included were 2590 patients (74% men) aged 63 ± 14 years. During the first month, 174 patients (6.7%) died. After adjustment, unmodifiable variables significantly associated with reduced 30-day survival were: age > 80 years (prevalence 15%; hazard ratio [HR] 2.7; 95% confidence interval [CI] 1.5-4.7), chronic kidney disease (2%; HR 5.3; 95% CI 2.6-11.1), diabetes mellitus (14%; HR 1.6; 95% CI 1.0-2.5), anterior or circumferential electrical localization (39%; HR 2.0; 95% CI 1.4-2.9), and Killip class 2, 3, or 4 (7%; HR 3.4; 95% CI 1.9-5.9; 2%; HR 10.1; 95% CI 5.3-19.4; 4%; HR 18; 95% CI 10.8-29.8, respectively). Among modifiable variables, total ischemic time > 3 hours (68%; HR 1.8; 95% CI 1.1-3.0), lack of appropriate premedication (18%; HR 2.2; 95% CI 1.5-3.3), and post-PCI TIMI < 3 (6%; HR 4.9; 95% CI 3.2-7.6) were significantly associated with reduced 30-day survival. Most predictors of 30-day survival post-STEMI are unmodifiable, but outcomes might be improved by optimizing modifiable factors, most importantly ischemic time and appropriate premedication.

Mid-term outcome of de novo lesions vs. in stent restenosis treated by intravascular lithotripsy procedures: Insights from the French Shock Initiative.

BACKGROUND: Intravascular lithotripsy (IVL) is a promising new technology for disrupting de-novo calcified coronary lesions (DNL) before percutaneous coronary intervention (PCI). We assessed 12-month outcomes of IVL in patients undergoing PCI for DNL or intra stent restenosis (ISR) lesions related to device underexpansion. METHODS: Prospective analysis of patients in the multicentre all-comers French Shock Initiative IVL registry. The primary safety endpoints in this analysis were in-hospital and 12-month major adverse cardiovascular events (MACE: cardiac death, myocardial infarction or target vessel revascularization). The primary effectiveness endpoint was procedural success, defined as <30% residual stenosis without severe angiographic complications. Event rates were analysed for the cohort and for DNL and ISR procedures separately. RESULTS: A total of 220 lesions were treated (76.7% DNL and 23.3% ISR) in 202 patients. Procedural success was achieved in 95.5% of patients (DNL group: 96.5%; ISR group: 92.0%). In-hospital MACE occurred in 6.4% of cases, mainly driven by periprocedural infarctions. The rate of MACE-free survival at 1 year was 86.6% in the overall cohort. Rates of target vessel (TVR) and lesion (TLR) revascularisation were 6.4% and 2.5%, respectively. The 1-year MACE rate was 91.5% in DNL group and 83.8% in ISR group. CONCLUSIONS: In this large all-comers IVL cohort, rates of in-hospital and 1-year MACE were moderate. The safety and efficiency of IVL was comparable in DNL and ISR lesions. A comparative study of the impact of IVL on outcomes appears warranted.

Evolution of TAVI patients and techniques over the past decade: The French TAVI registries.

BACKGROUND: The French transcatheter aortic valve implantation (TAVI) registries, linked with the nationwide administrative databases, have collected data on TAVI procedures from the first experience to current practices. OBJECTIVE: To investigate changes over the past decade in patient and procedural characteristics, major complications and mortality after TAVI. METHODS: Data from the France TAVI and FRANCE 2 registries, collected between 2010 and 2021, were linked using a probabilistic algorithm to the French national health single-payer claims database (SNDS). The algorithm created patient profiles from TAVI procedures in SNDS, matching them as closely as possible to the profiles in the registry databases. RESULTS: A total of 84,783 TAVI patients were included during the study period. The median age was 83 years (quartile 1, 79 years; quartile 3, 87 years) and remained stable over time. The median EuroSCORE 1 surgical risk score was 12.8 (quartile 1, 7.9; quartile 3, 21.0), and decreased over time. The number of procedures increased linearly, from 1556 in 2010 to 14,114 in 2021. The prevalence of iliofemoral access increased, whereas use of the other approaches decreased. Rates of in-hospital, 30-day and 1-year mortality per year were lower in patients undergoing TAVI after 2015, regardless of the surgical risk score. Finally, hospital length of stay decreased progressively, from 8 days in 2010 to 4 days in 2021. CONCLUSION: The TAVI registries provide the cornerstone for recording changes in TAVI. Over the past decade, patient profiles have improved whereas their age has remained stable. Simplification of the procedure reduced rates of death and major complications as well as length of hospital stay.

Indirect Transfer to Catheterization Laboratory for ST Elevation Myocardial Infarction Is Associated With Mortality Independent of System Delays: Insights From the France-PCI Registry.

Background: First medical contact (FMC)-to-balloon time is associated with outcome of ST-elevation myocardial infarction (STEMI). We assessed the impact on mortality and the determinants of indirect vs. direct transfer to the cardiac catheterization laboratory (CCL). Methods: We analyzed data from 2,206 STEMI patients consecutively included in a prospective multiregional percutaneous coronary intervention (PCI) registry. The primary endpoint was 1-year mortality. The impact of indirect admission to CCL on mortality was assessed using Cox models adjusted on FMC-to-balloon time and covariables unequally distributed between groups. A multivariable logistic regression model assessed determinants of indirect transfer. Results: A total of 359 (16.3%) and 1847 (83.7%) were indirectly and directly admitted for PCI. Indirect admission was associated with higher risk features, different FMCs and suboptimal pre-PCI antithrombotic therapy.At 1-year follow-up, 51 (14.6%) and 137 (7.7%) were dead in the indirect and direct admission groups, respectively (adjusted-HR 1.73; 95% CI 1.22-2.45). The association of indirect admission with mortality was independent of pre-FMC and FMC characteristics. Older age, paramedics- and private physician-FMCs were independent determinants of indirect admission (adjusted-HRs 1.02 per year, 95% CI 1.003-1.03; 5.94, 95% CI 5.94 3.89-9.01; 3.41; 95% CI 1.86-6.2, respectively). Conclusions: Our study showed that, indirect admission to PCI for STEMI is associated with 1-year mortality independent of FMC to balloon time and should be considered as an indicator of quality of care. Indirect admission is associated with higher-risk features and suboptimal antithrombotic therapy. Older age, paramedics-FMC and self-presentation to a private physician were independently associated with indirect admission. Our study, supports population education especially targeting elderly, more adequately dispatched FMC and improved pre-CCL management.

2-Year Results With a Sirolimus-Eluting Self-Expanding Stent for Femoropopliteal Lesions: The First-in-Human ILLUMINA Study.

OBJECTIVES: The aim of the study was to assess 24-month efficacy and safety of a novel drug-eluting stent (DES) for femoropopliteal interventions with an innovative stent design and abluminal reservoir technology releasing the amphilimus formulation (sirolimus plus fatty acid) for efficient drug transfer and optimized release kinetics. BACKGROUND: DES releasing paclitaxel exhibited good patency rates after femoropopliteal interventions. No benefit has been reported when sirolimus or everolimus were used for antiproliferative stent coating. METHODS: Within a multicenter, first-in-man, single-arm study, 100 patients with symptomatic femoropopliteal disease (Rutherford category 2-4, mean lesion length 5.8 ± 3.9 cm, 35.0% total occlusions) were treated with the NiTiDES stent (Alvimedica). Two-year follow-up included assessment of primary patency (defined as absence of clinically driven target lesion revascularization or binary restenosis with a peak systolic velocity ratio >2.4 by duplex ultrasound), safety, functional, and clinical outcomes. RESULTS: At 24 months, Kaplan-Meier estimates of primary patency and freedom from clinically driven target lesion revascularization were 83.4% (95% CI: 73.9%-89.6%) and 93.1% (95% CI: 85.3%-96.9%), respectively. Over the study period, 3 deaths were reported with no major limb amputation. Functional and clinical benefits were sustained, as 82.1% of patients fell into Rutherford category 0 or 1 at 24 months, which was associated with preserved improvements in all walking disability questionnaire scores. CONCLUSIONS: The 2-year results of the ILLUMINA (Innovative siroLimus seLf expanding drUg-eluting stent for the treatMent of perIpheral disease: evaluation of safety aNd efficAcy) study demonstrate a sustained treatment benefit with a novel sirolimus-eluting stent that also compares favorably to other femoropopliteal intervention trials. Head-to-head comparisons of NiTiDES with a paclitaxel-based DES are warranted. (The ILLUMINA Study [ILLUMINA]; NCT03510676).

Mechanical complications in ST-elevation myocardial infarction: The impact of pre-hospital delay.

AIMS: Mechanical complications (MC) (i.e., free wall rupture (FWR), papillary muscle rupture (PMR) and ventricular septal rupture (VSR)) are rare complications of ST- elevation acute myocardial infarction (STEMI). Incidence of MC according to pre-hospital delay remains unknown. We aimed to determine the rates of MC according to pre-hospital delay. METHODS: Analysis was conducted on the MODIF registry data. Patients were allocated to four groups according to pre-hospital delay: 0 to 12 h, 12 to 24 h, 24 to 36 h and 36 to 48 h. RESULTS: 6185 patients with complete data were analyzed. Mean age was 64.1 years old and 75.7% of patients were males. Eighty-three patients (1.34%) presented with MC: 44 (0.71%) experienced a FWR, 17 (0.27%) a PMR, and 22 (0.36%) a VSR. Global rates of MC were 0.82%, 1.43%, 1.24% and 5.07% in the four groups of pre-hospital delays - 0 to 12 h, 12 to 24 h, 24 to 36 h and 36 to 48 h - respectively (p < 0.001). In-hospital mortality rates were high: 44.2%, 47.1% and 54.6% for FWR, PMR and VSR, respectively. In multivariate analysis, factors independently related to the occurrence of MC were older age, female sex, simultaneous COVID-19 infection, absence of dyslipidemia, initial TIMI flow 0 or 1 in the culprit artery, 36 to 48 h-pre-hospital delay and absence of revascularization by percutaneous coronary intervention (PCI) with stent implantation. CONCLUSION: The probability of MC in STEMI increases with pre-hospital delay. Mechanical complications of STEMI remain associated with a very poor prognosis.

TAVR Patients Requiring Anticoagulation: Direct Oral Anticoagulant or Vitamin K Antagonist?

OBJECTIVES: Using French transcatheter aortic valve replacement (TAVR) registries linked with the nationwide administrative databases, the study compared the rates of long-term mortality, bleeding, and ischemic events after TAVR in patients requiring oral anticoagulation with direct oral anticoagulants (DOACs) or vitamin K antagonists (VKAs). BACKGROUND: The choice of optimal drug for anticoagulation after TAVR remains debated. METHODS: Data from the France-TAVI and FRANCE-2 registries were linked to the French national health single-payer claims database, from 2010 to 2017. Propensity score matching was used to reduce treatment-selection bias. Two primary endpoints were death from any cause (efficacy) and major bleeding (safety). RESULTS: A total of 24,581 patients who underwent TAVR were included and 8,962 (36.4%) were treated with OAC. Among anticoagulated patients, 2,180 (24.3%) were on DOACs. After propensity matching, at 3 years, mortality (hazard ratio [HR]: 1.37; 95% confidence interval [CI]: 1.12-1.67; P < 0.005) and major bleeding including hemorrhagic stroke (HR: 1.64; 95% CI: 1.17-2.29; P < 0.005) were lower in patients on DOACs compared with those on VKAs. The rates of ischemic stroke (HR: 1.32; 95% CI: 0.81-2.15; P = 0.27) and acute coronary syndrome (HR: 1.17; 95% CI: 0.68-1.99; P = 0.57) did not differ among groups. CONCLUSIONS: In these large multicenter French TAVR registries with an exhaustive clinical follow-up, the long-term mortality and major bleeding were lower with DOACs than VKAs at discharge. The present study supports preferential use of DOACs rather than VKAs in patients requiring oral anticoagulation therapy after TAVR.

Is coronary multivessel disease in acute myocardial infarction patients still associated with worse clinical outcomes at 1-year?

BACKGROUND: ST-elevation myocardial infarction (STEMI) patients with multivessel disease (MVD) are associated with a worse prognosis. However, few comparisons are available according to coronary status in the era of modern reperfusion and optimized secondary prevention. HYPOTHESIS: We hypothesized that the difference in prognosis according to number of vessel disease in STEMI patients has reduced. METHODS: All consecutive STEMI patients undergoing primary percutaneous coronary intervention (PCI) within 24 h of symptoms onset between January 1, 2014 and June 30, 2016 enrolled in the CRAC (Club Régional des Angioplasticiens de la région Centre) France PCI registry were analyzed. Baseline characteristics, management, and outcomes at 1-year were analyzed according to coronary status (one-, two-, and three-VD). RESULTS: A total of 1886 patients (mean age 62.2 ± 14.0 year; 74% of male) were included. Patients with MVD (two or three-VD) represented 53.7%. They were older with higher cardiovascular risk factor profile. At 1 year, the rate of major adverse cardiovascular events (MACE, defined as all-cause death, stroke or re-MI) was 10%, 12%, and 12% in one-, two, and three-VD respectively (p = .28). In multivariable adjusted Cox proportional hazard regression model, two- and three-VD were not associated with higher rate of MACE compared to patients with single VD (HR, 1.09; 95%CI 0.76-1.56 for two-VD; HR, 0.74; 95%CI 0.48-1.14 for three-VD). CONCLUSIONS: MVD still represents an important proportion of STEMI patients but their prognoses were not associated with worse clinical outcomes at 1-year compared with one-VD patients in a modern reperfusion area and secondary medication prevention.

Use and outcomes of the PK Papyrus covered stent in France: SOS PK Papyrus Registry.

OBJECTIVES: To evaluate the rate of procedural success and long-term outcomes of the PK Papyrus (PKP) covered stent (CS). BACKGROUND: CS are essential in the treatment of coronary artery perforation (CAP). They have also been used to treat coronary artery aneurysms. Limited evidence is available on clinical outcomes with the PKP. METHODS: This was a multicenter, observational, retrospective, and prospective study. Consecutive patients undergoing intentional PKP implantation in 22 centers in France were included. The primary endpoint was the rate of procedural success. Secondary endpoints included rates of death, myocardial infarction (MI), target lesion revascularization (TLR), in-stent restenosis (ISR), and stent thrombosis (ST). RESULTS: Data from 130 patients were analyzed (mean age 72.5 ± 10.5 years; 71% men). The main indication for PKP was CAP, in 84 patients (65%). Delivery success was achieved in 95% and procedural success in 91%. During the in-hospital stay, 15 patients died (12%) and 7 (5%) presented with ST. Data from 127 patients were available at 19.2 ± 12.8 month follow-up. Thirty-three patients died (26%), 15 (12%) had an MI and 21 (17%) presented with TLR. TLR was due to ISR in 12 patients (9%), 10 had definite ST (8%) and 1 patient for stent under-expansion. CONCLUSIONS: The principal indication for PKP was CAP. PKP had high rates of delivery and procedural success. At long-term follow-up, there was a high rate of TLR, mainly due to ISR and ST. These results are consistent with previously reported data in these clinical settings.

Two-year outcomes after percutaneous coronary intervention with drug-eluting stents or bare-metal stents in elderly patients with coronary artery disease.

OBJECTIVES: Report the results at 2 years of the patients included in the SENIOR trial. BACKGROUND: Patients above 75 years of age represent a fast-growing population in the cathlab. In the SENIOR trial, patients treated by percutaneous coronary intervention (PCI) with drug eluting stent (DES) and a short duration of P2Y12 inhibitor (1 and 6 months for stable and unstable coronary syndromes, respectively) compared with bare metal stents (BMS) was associated with a 29% reduction in the rate of all-cause mortality, myocardial infarction (MI), stroke, and ischaemia-driven target lesion revascularization (ID-TLR) at 1 year. The results at 2 years are reported here. METHODS AND RESULTS: We randomly assigned 1,200 patients (596[50%] to the DES group and 604[50%] to the BMS group). At 2 years, the composite endpoint of all-cause mortality, MI, stroke and ID-TLR had occurred in 116 (20%) patients in the DES group and 131 (22%) patients in the BMS group (RR 0.90 [95%CI 0.72-1.13], p = .37). IDTLR occurred in 14 (2%) patients in the DES group and 41 (7%) patients in the BMS group (RR 0.35 [95%CI 0.16-0.60], p = .0002). Major bleedings (BARC 3-5) occurred in 27(5%) patients in both groups (RR 1.00, [95%CI 0.58-1.75], p = .99). Stent thrombosis rates were low and similar between DES and BMS (0.8 vs 1.3%, (RR 0.52 [95%CI 0.01-1.95], p = .27). CONCLUSION: Among elderly PCI patients, a strategy combining a DES together with a short duration of DAPT is associated with a reduction in revascularization up to 2 years compared with BMS with very few late events and without any increased in bleeding complications or stent thrombosis.

Incidence, delays, and outcomes of STEMI during COVID-19 outbreak: Analysis from the France PCI registry.

Objectives: The aim of this study was to assess the impact of the coronavirus disease 2019 (COVID-19) outbreak on incidence, delays, and outcomes of ST-elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PPCI) in France. Methods: We analyzed all patients undergoing PPCI <24 hours STEMI included in the prospective France PCI registry. The 2 groups were compared on mean monthly number of patients, delays in the pathway care, and in-hospital major adverse cardiac events (MACE: death, stent thrombosis, myocardial infarction, unplanned coronary revascularization, stroke, and major bleeding). Results: From January 15, 2019 to April 14, 2020, 2064 STEMI patients undergoing PPCI were included: 1942 in the prelockdown group and 122 in the lockdown group. Only 2 cases in the lockdown group were positive for COVID-19. A significant drop (12%) in mean number of STEMI/month was observed in the lockdown group compared with prelockdown (139 vs 122, P < 0.04). A significant increase in "symptom onset to first medical contact" delay was found for patients who presented directly to the emergency department (ED) (238 minutes vs 450 minutes; P = 0.04). There were higher rates of in-hospital MACE (7.7% vs 12.3%; P = 0.06) and mortality (4.9% vs 8.2%; P = 0.11) in the lockdown group but the differences were not significant. Conclusion: According to the multicenter France PCI registry, the COVID-19 outbreak in France was associated with a significant decline in STEMI undergoing PPCI and longer transfer time for patients who presented directly to the ED. Mortality rates doubled, but the difference was not statistically significant.

Successful linkage of French large-scale national registry populations to national reimbursement data: Improved data completeness and minimized loss to follow-up.

BACKGROUND: Registries, a cornerstone of contemporary medicine, frequently suffer from incomplete documentation and losses to follow-up. By linking data to a single-payer national claims database, national registries may be enriched and the quality enhanced. AIMS: To explore the value of data from the French Système National des Données de Santé (SNDS) as a resource to enhance the quality of registries when combined with data from electronic case report forms, and to assess the power to minimize data gaps and losses to follow-up. METHODS: A probabilistic algorithm was developed to link and match records in the SNDS with patient data from the electronic case report forms of two registries on transcatheter aortic valve implantation: FRANCE-2 and FRANCE-TAVI. The algorithm created patient profiles from transcatheter aortic valve implantation procedures in the SNDS, matching them as closely as possible to the profiles in the registry databases. The objective was to achieve 90% linkage of the populations. The linked database was analysed for completeness and loss to follow-up. For validation, mortality curves for the linked registry cohorts were compared with those for the original populations. RESULTS: A total of 34,397 unique registries entries were identified, and 89.9% of patients in the SNDS could be linked. Rates of losses to follow-up over 2 years were 1.0% in the linked FRANCE-TAVI population compared with 40.3% based on electronic case report form documentation. For FRANCE-2, 3-year rates of losses to follow-up were 1.7% and 6.1%, respectively. Mortality curves for populations based on SNDS and electronic case report form data were practically superimposable. CONCLUSIONS: Linking data from a single-payer national claims database to national registries using a probabilistic approach is feasible and can close data gaps and practically abolish losses to follow-up in the registry population.

A Polymer-Free Paclitaxel-Eluting Stent Versus a Bare-Metal Stent for De Novo Femoropopliteal Lesions: The BATTLE Trial.

OBJECTIVES: The primary objective of the BATTLE (Bare Metal Stent vs. Paclitaxel Eluting Stent in the Setting of Primary Stenting of Intermediate-Length Femoropopliteal Lesions) trial is to demonstrate the clinical superiority of the Zilver PTX stent over the Misago stent in the treatment of femoropopliteal lesions. BACKGROUND: No randomized studies have compared self-expanding paclitaxel-eluting stents with bare-metal stents in the treatment of femoropopliteal lesions. METHODS: BATTLE is a multicenter randomized controlled trial in patients with symptomatic (Rutherford category 2 to 5) de novo lesions of the superficial femoral or proximal popliteal artery. The primary endpoint is freedom from in-stent restenosis (ISR) at 1 year, with restenosis defined as a peak systolic velocity index >2.4 at the target lesion. The Kaplan-Meier method was used to evaluate time-to-event data for freedom from ISR over the 2-year follow-up period. RESULTS: Between March 2014 and August 2016, 186 patients were enrolled; 91 were assigned to the Misago arm and 90 to the Zilver PTX arm. Kaplan-Meier 1-year estimates of freedom from ISR were 88.6% for Misago and 91% for Zilver PTX (hazard ratio [HR]: 1.2; 95% confidence interval [CI]: 0.6 to 2.4; p = 0.64). Comparing Misago with Zilver PTX, 2-year estimates were 6.4% and 1.2% (HR: 7.3; 95% CI: 0.9 to 59.3; p = 0.0632) for mortality, 74.6% and 78.8% (HR: 1.2; 95% CI: 0.6 to 2.1; p = 0.62) for patency, and 14.4% and 12.4% (HR: 1.2; 95% CI: 0.5 to 2.8; p = 0.69) for target lesion revascularization. CONCLUSIONS: In the treatment of symptomatic femoropopliteal lesions, the Zilver PTX stent failed to show superiority over the Misago stent in freedom from ISR at 1 year.
