Risk stratification of patients listed for heart transplantation while supported with extracorporeal membrane oxygenation.
Extracorporeal membrane oxygenation (ECMO) is used to support patients in severe cardiogenic shock. In the absence of recovery, these patients may need to be listed for heart transplant (HT), which offers the best long-term prognosis. However, posttransplantation mortality is significantly elevated in patients who receive ECMO. The objective of the present study was to describe and risk-stratify different profiles of patients listed for HT supported by ECMO. ⋯ The HT recipients in the ECMOREMOVED and ECMOBTT groups with no risk factors showed similar survival as the HT recipients who were never supported on ECMO. In the ECMOBTT group, posttransplantation mortality increased significantly with increasing risk factors.

Redefining "low risk": Outcomes of surgical aortic valve replacement in low-risk patients in the transcatheter aortic valve replacement era.
Guidelines suggest aortic valve replacement (AVR) for low-risk asymptomatic patients. Indications for transcatheter AVR now include low-risk patients, making it imperative to understand state-of-the-art surgical AVR (SAVR) in this population. Therefore, we compared SAVR outcomes in low-risk patients with those expected from Society of Thoracic Surgeons (STS) models and assessed their intermediate-term survival. ⋯ STS risk models overestimate contemporary SAVR risk at a high-volume center, supporting efforts to create a more agile quality assessment program. SAVR in low-risk patients provides durable survival benefit, supporting early surgery and providing a benchmark for transcatheter AVR.
