The principal pathogenic mechanisms giving rise to RV pathology include RV pressure overload, RV volume overload and RV myocardial diseases. Non-invasive cardiac imaging is commonly used to detect the conditions associated with RV disease and ultimately guide therapeutic decisions. Transthoracic echocardiogram is usually the first line test in patients with suspected RV disease and it provides relevant information on biventricular size and function, valvular abnormalities, and cardiac hemodynamics including pulmonary pressures. Cardiac magnetic resonance (CMR) is considered the reference standard non-invasive imaging test for quantifying ventricular size and function and cardiac shunts and has a secondary role for assessing valvular disease when echocardiography is nondiagnostic. CMR also provides insight into RV myocardial diseases such as inflammation, infarction and infiltration. Nuclear cardiology and cardiac computed tomography can also be used to inform on specific RV disease mechanisms originating from lung disease and pulmonary vasculature disorders.

Although artificially augmenting systemic flow by using temporary mechanical circulatory support (tMCS) devices would be expected to reduce the rate of progression to multiorgan dysfunction and thereby enhance survival, reliable evidence for benefit has remained elusive with lingering questions regarding the appropriate selection of both patients and devices, as well as the timing of device implantation relative to other critical interventions. Further complicating matters are the resource-intensive multidisciplinary systems of care that must be brought to bear in this complex patient population. Until recently, studies of tMCS were extremely heterogeneous in design, populations treated, and timing of device implantation with regard to shock onset and revascularization. Attempts at summarizing the available data had resulted in a lack of clear benefit for any type of tMCS modality. On this background, 2 landmark trials of tMCS in the setting of AMI-CS---ECLS-SHOCK and DanGer Shock---have recently been published with divergent results that deserve detailed consideration. Thus, we provide a detailed narrative review of the current state of knowledge regarding tMCS for AMI-CS.

The difficulty in treating CS lies in its complexity, phenotypic heterogeneity, and the need for expedient treatment. Emerging evidence suggests that cardiogenic shock teams (CS teams), consisting of multiple specialists working in tandem with set protocols and care pathways to offer standardized team-based care, may reduce mortality and morbidity in patients with CS. A key reason for improved outcomes may be the team’s decisions surrounding the use of temporary mechanical support devices (tMCS). CS teams expedite the identification of patients who require tMCS and determine the most appropriate device based on patient factors, including shock phenotype. The CS team ensures that tMCS best practices are followed and assists in determining the timing of device escalation or de-escalation. This article will discuss the rationale and role of CS teams. The evidence behind CS teams and their impact on tMCS decision making will be reviewed. Recent trial evidence for the use of tMCS in CS secondary to acute myocardial infarction (AMI) will be examined. Considerations for creating and optimizing an AMI-CS team will be highlighted. Finally, we will examine the current use of CS teams, potential challenges, and future directions for establishing CS teams in Canada.</div></div>","PeriodicalId":9555,"journal":{"name":"Canadian Journal of Cardiology","volume":"41 4","pages":"Pages 682-690"},"PeriodicalIF":5.8,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143373853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
