Cardiogenic Shock Management in the Modern Era: A Narrative Review of Percutaneous Mechanical Circulatory Support Devices

Srijit Jana, Makayla Wijesinghe, Michael V. DiCaro, KaChon Lei et autres

Cardiogenic shock (CS) remains a significant clinical challenge with persistently high mortality rates. Defined by impaired cardiac output resulting in end-organ hypoperfusion, CS commonly arises from acute myocardial infarction (AMI-CS) or acute exacerbations of heart failure (HF-CS). The severity of CS is …

Transcatheter Edge-to-Edge Repair for Severe Acute Mitral Valve Regurgitation in Diffuse Alveolar Hemorrhage: A Case Report

Jasmine K. Dugal, Vasiliki Tasouli-Drakou, Arpinder Malhi, Divyansh Sharma et autres

BACKGROUND Diffuse alveolar hemorrhage is rarely associated with acute mitral valve regurgitation. Emerging evidence of transcatheter edge-to-edge repair (TEER) use for treating acute mitral regurgitation has promoted TEER as a promising alternative to mitral valve surgery, owing to reduced mortality and complications. …
