In this review, the authors discuss a brief history of the Impella mechanical circulatory support device, a mechanistic role for the device in the context of the underlying pathophysiology of acute myocardial infarction cardiogenic shock (AMI-CS), the current body of literature evaluating its role in AMI-CS, and upcoming efforts to identify a role more clearly for the device in AMI-CS.

- The study investigates the effectiveness of revascularization combined with optimal medical therapy (OMT) versus OMT alone for patients with stable ischemic heart disease (SIHD), using a Bayesian approach to assess risks.
- Out of several trials reviewed, the findings indicate minimal differences in all-cause and cardiac mortality rates between the two treatment options, suggesting that revascularization does not significantly improve these outcomes.
- However, revascularization may lead to lower risks of heart attacks and unstable angina, while also increasing the likelihood of stroke compared to OMT alone.
Background: Limited data are available regarding clinical outcomes of valve-in-valve (ViV) transcatheter aortic valve implantation (TAVI) following the United States Food and Drug Administration approval of ViV TAVI in 2015.
Aims: The aim of this study was to evaluate in-hospital, 30-day, and 6-month outcomes of ViV TAVI versus repeat surgical aortic valve replacement (SAVR) in patients with a failed aortic bioprosthetic valve.
Methods: This retrospective cohort study identified patients who underwent ViV TAVI or repeat SAVR utilising the Nationwide Readmission Database from 2016 to 2018.

Objective: To study the association between dementia and post-TAVR outcomes.
Design: Cohort study with propensity-score matching was conducted using the Nationwide Inpatient Sample.
Importance: The coronavirus disease 2019 (COVID-19) pandemic has resulted in severe psychological, social, and economic stress in people's lives. It is not known whether the stress of the pandemic is associated with an increase in the incidence of stress cardiomyopathy.
Objective: To determine the incidence and outcomes of stress cardiomyopathy during the COVID-19 pandemic compared with before the pandemic.
Recurrent in-stent restenosis (R-ISR) refers to the re-occlusion of a successfully treated in-stent restenosis. Much of the present understanding of this condition stems from studies on in-stent restenosis, as literature on R-ISR is sparse. Compounded by multiple previous struts, narrower luminal diameters and worse patient profiles, R-ISR is a clinical challenge that demands urgent attention.

There are limited data on the weekend effect for nonelective coronary artery bypass grafting (CABG).
Methods: We studied outcomes for weekend vs weekday operations for all adult patients in the 2013 to 2014 National Inpatient Sample (NIS) undergoing nonelective CABG.
