RESUMO
BACKGROUND AND AIMS: There is significant potential to streamline the clinical pathway for patients undergoing transcatheter aortic valve implantation (TAVI). The purpose of this study was to evaluate the effect of implementing BENCHMARK best practices on the efficiency and safety of TAVI in 28 sites in 7 European countries. METHODS: This was a study of patients with severe symptomatic aortic stenosis (AS) undergoing TAVI with balloon-expandable valves before and after implementation of BENCHMARK best practices. Principal objectives were to reduce hospital length of stay (LoS) and duration of intensive care stay. Secondary objective was to document patient safety. RESULTS: Between January 2020 and March 2023, 897 patients were documented prior to and 1491 patients after the implementation of BENCHMARK practices. Patient characteristics were consistent with a known older TAVI population and only minor differences. Mean LoS was reduced from 7.7 ± 7.0 to 5.8 ± 5.6 days (median 6 vs. 4 days; P < .001). Duration of intensive care was reduced from 1.8 to 1.3 days (median 1.1 vs. 0.9 days; P < .001). Adoption of peri-procedure best practices led to increased use of local anaesthesia (96.1% vs. 84.3%; P < .001) and decreased procedure (median 47 vs. 60â min; P < .001) and intervention times (85 vs. 95â min; P < .001). Thirty-day patient safety did not appear to be compromised with no differences in all-cause mortality (0.6% in both groups combined), stroke/transient ischaemic attack (1.4%), life-threatening bleeding (1.3%), stage 2/3 acute kidney injury (0.7%), and valve-related readmission (1.2%). CONCLUSIONS: Broad implementation of BENCHMARK practices contributes to improving efficiency of TAVI pathway reducing LoS and costs without compromising patient safety.

One of the most frequent complications following coronary revascularization is cardiac myonecrosis characterized by an elevation of cardiac biomarkers, particularly with the implementation of high-sensitivity cardiac troponin. In the last decades, various definitions of periprocedural myocardial injury and infarction have been proposed, based on different cardiac biomarkers, various thresholds, and the need for additional ischemic features. In this review, we aim at providing insights on the mechanisms involved in periprocedural myocardial injury and infarction following percutaneous coronary intervention or coronary artery bypass grafting, the strengths and limitations of the available definitions and their clinical implications. We also provide an updated description of preventive strategies that have been evaluated in randomized controlled trials to avoid these complications as well as patient-level and lesion-level risk factors to better anticipate and rebalance the indication for coronary revascularization and plan adequate post-procedure monitoring.
RESUMO
Since the first description of takotsubo syndrome 30 years ago, only a little is known on the underlying physiopathology leading to peculiar left ventricular function alteration and myocardial damage related to acute emotional or physical stress. In the present case, we used continuous invasive thermodilution to evaluate coronary microvascular function at the acute phase of takotsubo and after recovery. The acute phase of takotsubo was characterized by a reduced coronary output and altered reserved flow with persistently high resistance during hyperaemia. At 6 weeks, we described a complete recovery of microvascular function, concomitant to LVEF recovery.

Percutaneous transcatheter structural heart interventions have considerably expanded within the last two decades, improving clinical outcomes and quality of life versus guideline-directed medical therapy for patients frequently ineligible for surgical treatment. Transcatheter structural heart interventions comprise valve implantation or repair and also occlusions of the patent foramen ovale, atrial septal defects and left atrial appendage. These procedures expose structural devices to arterial or venous blood flow with various rheological conditions leading to potential thrombotic complications and embolisation. Furthermore, these procedures may concern comorbid patients at high risk of both ischaemic and bleeding complications. This state-of-the-art review provides a description of the device-related thrombotic risk associated with these transcatheter structural heart interventions and of the current evidence-based guidelines regarding antithrombotic treatments. Gaps in evidence for each of the studied transcatheter interventions and the main ongoing trials are also summarised.

BACKGROUND: The ACTION-SHOCK registry offers a decade-long perspective on patients admitted with cardiogenic shock (CS). AIMS: To assess trends in the management and outcomes of patients with CS over 10 years. METHODS: Trends in the characteristics, management and outcomes of patients with CS admitted into the cardiac intensive care unit of Pitié-Salpêtrière hospital from 2011 to 2020 were analysed. Short-term outcomes included in-hospital mortality, heart transplantation or ventricular assist device. Long-term outcomes were all-cause death or readmission for acute heart failure at 1 year. RESULTS: Over a 10-year period, data from 700 patients with CS (median [interquartile range] age 61 [50-72] years; 73% of men) were analysed. The proportion of CS related to acute myocardial infarction decreased (from 45% in 2011-2012 to 27% in 2019-2020) while the proportions related to chronic coronary syndrome (18% to 23%) and non-ischaemic cardiomyopathies (37 to 51%) increased (P<0.01). The use of rescue extracorporeal membrane oxygenation remained stable (19 to 14%) and intra-aortic balloon pump use decreased (22% to 7%) (P<0.01). In-hospital mortality remained stable (27 to 29%) as did the proportions of patients discharged after transplantation (17 to 14%) or with a durable ventricular assist device (2 to 4%). Among patients discharged alive, death or readmission for acute heart failure at 1 year remained high (37 to 47%). CONCLUSION: CS remained associated with a poor prognosis over the last decade. There are significant unmet needs in the management strategies of patients with CS.
RESUMO
BACKGROUND: Whether ticagrelor in chronic coronary syndrome patients undergoing complex percutaneous coronary intervention (PCI) can prevent cardiovascular events is unknown. OBJECTIVES: The authors sought to evaluate outcomes of complex PCI and the efficacy of ticagrelor vs clopidogrel in stable patients randomized in the ALPHEUS (Assessment of Loading with the P2Y12 inhibitor ticagrelor or clopidogrel to Halt ischemic Events in patients Undergoing elective coronary Stenting) trial. METHODS: All PCI procedures were blindly reviewed and classified as complex if they had at least 1 of the following criteria: stent length >60 mm, 2-stent bifurcation, left main, bypass graft, chronic total occlusion, use of atherectomy or guiding catheter extensions, multiwire technique, multiple stents. The primary endpoint was a composite of type 4a or b myocardial infarction (MI) and major myocardial injury during the 48 hours after PCI. We compared the event rates according to the presence or not of complex PCI criteria and evaluated the interaction with ticagrelor or clopidogrel. RESULTS: Among the 1,866 patients randomized, 910 PCI (48.3%) were classified as complex PCI. The primary endpoint was more frequent in complex PCI (45.6% vs 26.6%; P < 0.001) driven by higher rates of type 4 MI and angiographic complications (12.2% vs 4.8 %; P < 0.001 and 19.3% vs 8.6%; P < 0.05, respectively). The composite of death, MI, and stroke at 48 hours (12.7% vs 5.1 %; P < 0.05) and at 30 days (13.4% vs 5.3%; P < 0.05) was more frequent in complex PCI. No interaction was found between PCI complexity and the randomized treatment for the primary endpoint (Pinteraction = 0.47) nor the secondary endpoints. CONCLUSIONS: In chronic coronary syndrome, patients undergoing a complex PCI have higher rates of periprocedural and cardiovascular events that are not reduced by ticagrelor as compared with clopidogrel.

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 identification and management of patients at high bleeding risk (HBR) undergoing transcatheter aortic valve implantation (TAVI) are of major importance, but the lack of standardised definitions is challenging for trial design, data interpretation, and clinical decision-making. The Valve Academic Research Consortium for High Bleeding Risk (VARC-HBR) is a collaboration among leading research organisations, regulatory authorities, and physician-scientists from Europe, the USA, and Asia, with a major focus on TAVI-related bleeding. VARC-HBR is an initiative of the CERC (Cardiovascular European Research Center), aiming to develop a consensus definition of TAVI patients at HBR, based on a systematic review of the available evidence, to provide consistency for future clinical trials, clinical decision-making, and regulatory review. This document represents the first pragmatic approach to a consistent definition of HBR evaluating the safety and effectiveness of procedures, devices and drug regimens for patients undergoing TAVI..

Introduction: Dual antithrombotic therapy (DAT) combining oral anticoagulation (OAC), preferentially Non-vitamin K antagonist OAC (NOAC) and single antiplatelet therapy (SAPT) for a period of 6-12 months is recommended after percutaneous coronary intervention (PCI) in patients with an indication for OAC. Objective: To compare outcomes between vitamin K antagonist (VKA) and NOAC-treated patients in the nation-wide France PCI registry. Methods: All consecutive patients from the France PCI registry treated by PCI and discharged with OAC between 2014 and 2020 were included and followed one-year. Major bleeding was defined as Bleeding Academic Research Consortium (BARC) classification ≥3 and major adverse cardiac events (MACE) as the composite of all-cause mortality, myocardial infarction (MI), and ischemic stroke. A propensity-score analysis was used. Results: Of the 7,277 eligible participants, 2,432 (33.4%) were discharged on VKA and 4,845 (66.6%) on NOAC. After propensity-score adjustment, one-year major bleeding was less frequent in NOAC vs. VKA-treated participants [3.1% vs. 5.2%, -2.1% (-3.6% to -0.6%), p = 0.005 as well as the rate of MACE [9.2% vs. 11.9%, -2.7% (-5.0% to -0.4%), p = 0.02]. One-year mortality was also significantly decreased in NOAC vs. VKA-treated participants [7.4% vs. 9.9%, -2.6% (-4.7% to -0.5%), p = 0.02]. The area under ROC curves of the anticoagulant treatment propensity score was estimated at 0.93, suggesting potential indication bias. Conclusions: NOAC seems to have a better efficacy and safety profile than VKA. However, potential indication bias were found.
