In the realm of innovative medical procedures, TEER (transcatheter edge-to-edge repair) has emerged as a promising field, showcasing significant growth and advancements. Mitral TEER has been performed for the last two decades; in contrast, tricuspid TEER is newer, with long-term outcomes pending. This article aims to provide a comprehensive review of the current literature, with a primary focus on outcomes and potential complications associated with both procedures. Both procedures carry a low risk of complications when done by experienced providers. A team approach involving specialists in cardiology, cardiothoracic surgery, cardiac imaging and heart failure ensures comprehensive care. A unified approach encompassing preprocedural workup, risk assessment, and standardised care throughout the procedure and recovery contributes to successful outcomes.

Abstract Aims Anticoagulants are the mainstay treatment for stroke prevention in patients with non-valvular atrial fibrillation (NVAF), and the CHA2DS2-VASc score is widely used to guide anticoagulation therapy in this cohort. However, utility of CHA2DS2-VASc in NVAF patients is debated, primarily because it is a vascular scoring system, which does not incorporate atrial fibrillation related parameters. Therefore, we conducted a meta-analysis to estimate the discrimination ability of CHA2DS2-VASc in predicting ischaemic stroke overall, and in subgroups of patients with or without NVAF. Methods and results PubMed and Embase databases were searched till June 2020 for published articles that assessed the discrimination ability of CHA2DS2-VASc, as measured by C-statistics, during mid-term (2–5 years) and long-term (>5 years) follow-up. Summary estimates were reported as random effects C-statistics with 95% confidence intervals (CIs). Seventeen articles were included in the analysis. Nine studies (n = 453 747 patients) reported the discrimination ability of CHA2DS2-VASc in NVAF patients, and 10 studies (n = 138 262 patients) in patients without NVAF. During mid-term follow-up, CHA2DS2-VASc predicted stroke with modest discrimination in the overall cohort [0.67 (0.65–0.69)], with similar discrimination ability in patients with NVAF [0.65 (0.63–0.68)] and in those without NVAF [0.69 (0.68–0.71)] (P-interaction = 0.08). Similarly, at long-term follow-up, CHA2DS2-VASc had modest discrimination [0.66 (0.63–0.69)], which was consistent among patients with NVAF [0.63 (0.54–0.71)] and those without NVAF [0.67 (0.64–0.70)] (P-interaction = 0.39). Conclusion This meta-analysis suggests that the discrimination power of the CHA2DS2-VASc score in predicting ischaemic stroke is modest, and is similar in the presence or absence of NVAF. More accurate stroke prediction models are thus needed for the NVAF population.

Background: There are limited data on acute myocardial infarction with cardiogenic shock (AMI-CS) stratified by chronic kidney disease (CKD) stages. Objective: To assess clinical outcomes in AMI-CS stratified by CKD stages. Methods: A retrospective cohort of AMI-CS during 2005–2016 from the National Inpatient Sample was categorized as no CKD, CKD stage-III (CKD-III), CKD stage-IV (CKD-IV) and end-stage renal disease (ESRD). CKD-I/II were excluded. Outcomes included in-hospital mortality, use of coronary angiography, percutaneous coronary intervention (PCI) and mechanical circulatory support (MCS). We also evaluated acute kidney injury (AKI) and acute hemodialysis in non-ESRD admissions. Results: Of 372,412 AMI-CS admissions, CKD-III, CKD-IV and ESRD comprised 20,380 (5.5%), 7367 (2.0%) and 18,109 (4.9%), respectively. Admissions with CKD were, on average, older, of the White race, bearing Medicare insurance, of a lower socioeconomic stratum, with higher comorbidities, and higher rates of acute organ failure. Compared to the cohort without CKD, CKD-III, CKD-IV and ESRD had lower use of coronary angiography (72.7%, 67.1%, 56.9%, 61.1%), PCI (53.7%, 43.8%, 38.4%, 37.6%) and MCS (47.9%, 38.3%, 33.3%, 34.2%), respectively (all p < 0.001). AKI and acute hemodialysis use increased with increase in CKD stage (no CKD–38.5%, 2.6%; CKD-III–79.1%, 6.5%; CKD-IV–84.3%, 12.3%; p < 0.001). ESRD (adjusted odds ratio [OR] 1.25 [95% confidence interval {CI} 1.21–1.31]; p < 0.001), but not CKD-III (OR 0.72 [95% CI 0.69–0.75); p < 0.001) or CKD-IV (OR 0.82 [95 CI 0.77–0.87] was predictive of in-hospital mortality. Conclusions: CKD/ESRD is associated with lower use of evidence-based therapies. ESRD was an independent predictor of higher in-hospital mortality in AMI-CS.

Background: There are limited data on how sex influences the outcomes of acute myocardial infarction-cardiogenic shock (AMI-CS) in young adults. Methods: A retrospective cohort of AMI-CS admissions aged 18 to 55 years, during 2000 to 2017, was identified using the National Inpatient Sample. Use of coronary angiography, percutaneous coronary intervention, mechanical circulatory support and noncardiac interventions was identified. Outcomes of interest included in-hospital mortality, use of cardiac interventions, hospitalization costs, and length of stay. Results: A total 90 648 AMI-CS admissions ≤55 years of age were included, of which 26% were women. Higher rates of CS were noted in men (2.2% in 2000 to 4.8% in 2017) compared with women (2.6% in 2000 to 4.0% in 2017; P <0.001). Compared with men, women with AMI-CS were more frequently of Black race, from a lower socioeconomic status, with higher comorbidity, and admitted to rural and small hospitals (all P <0.001). Women had lower rates of ST-segment elevation presentation (73.0% versus 78.7%), acute noncardiac organ failure, cardiac arrest (34.3% versus 35.7%), and received less-frequent coronary angiography (78.3% versus 81.4%), early coronary angiography (49.2% versus 54.1%), percutaneous coronary intervention (59.2% versus 64.0%), and mechanical circulatory support (50.3% versus 59.2%; all P <0.001). Female sex was an independent predictor of in-hospital mortality (23.0% versus 21.7%; adjusted odds ratio, 1.11 [95% CI, 1.07–1.16]; P <0.001). Women had lower hospitalization costs ($156 372±$198 452 versus $167 669±$208 577; P <0.001) but comparable lengths of stay compared with men. Conclusions: In young AMI-CS admissions, women are treated less aggressively and experience higher in-hospital mortality than men.

Abstract Aims To evaluate sex-specific disparities in acute kidney injury (AKI) complicating acute myocardial infarction-related cardiogenic shock (AMI-CS) in the United States. Methods and results This was a retrospective cohort study from 2000 to 2014 from the National Inpatient Sample (20% sample of all hospitals in the United States). Patients &gt;18 years admitted with a primary diagnosis of AMI and concomitant CS that developed AKI were included. The endpoints of interest were the prevalence, trends, and outcomes of men and women with AKI in AMI-CS. Multivariable hierarchical logistic regression was used to control for confounding, and a two-sided P &lt; 0.05 was considered statistically significant. During this 15 year period, 440 257 admissions with AMI-CS met the inclusion criteria, with AKI noted in 155 610 (35.3%). Women constituted 36.3% of the cohort and were older, of non-White race, and with higher co-morbidity compared with men. Women with AKI less often received coronary angiography (59% vs. 66%), percutaneous coronary intervention (39% vs. 43%), mechanical circulatory support (39% vs. 48%), mechanical ventilation (49% vs. 54%), and haemodialysis (9% vs. 10%) compared with men (all P &lt; 0.001). Adjusted in-hospital mortality was higher in women—odds ratio 1.16 (95% confidence interval 1.14–1.19); P &lt; 0.001—compared with men. Women had shorter lengths of stay (12 ± 14 vs. 13 ± 14 days), lower hospital costs ($150 071 ± 180 796 vs. $181 260 ± 209 674), and were less often discharged to home (19% vs. 31%) (all P &lt; 0.001). Conclusions Women with AKI in AMI-CS received fewer cardiac and non-cardiac interventions, had higher in-hospital mortality, and were less often discharged to home compared with men.
