Purpose Of Review: Extracorporeal membrane oxygenation (ECMO) is increasingly used to temporarily support patients in severe circulatory and/or respiratory failure. Echocardiography is a core component of successful ECMO deployment. Herein, we review the role of echocardiography at different phases on extracorporeal support including candidate identification, cannulation, maintenance, complication vigilance, and decannulation.
Recent Findings: During cannulation, ultrasound is used to confirm intended vascular access and appropriate inflow cannula positioning. While on ECMO, echocardiographic evaluation of ventricular loading conditions and hemodynamics, cannula positioning, and surveillance for intracardiac or aortic thrombi is needed for complication mitigation. Echocardiography is crucial during all phases of ECMO use. Specific echocardiographic queries depend on the ECMO type, V-V, or V-A, and the specific cannula configuration strategy employed.

Echocardiographic index of left ventricular performance for prognostication in transthyretin cardiac amyloidosis: the central role of stroke volume index.
J Cardiovasc Med (Hagerstown)

Introduction: Cardiac amyloidosis typically causes restrictive cardiomyopathy, in which the impairment of diastolic function is dominant. Echocardiography provides prognostic information through some important parameters: left ventricular ejection fraction (LVEF) and global longitudinal strain (GLS). However, LVEF often remains preserved despite disease progression, and GLS is not routinely performed as it is limited by suboptimal image quality.

Total anomalous pulmonary venous return (TAPVR) is a high risk and rare cardiac malformation with a low prenatal detection rate and predicting obstruction in these cases is difficult. We sought to investigate fetal echocardiographic parameters associated with postnatal pulmonary venous obstruction (PPVO). We performed a retrospective review of 26 patients with TAPVR who had a fetal echocardiogram from 2010 to 2021.

Background: Cardiac involvement represents the main cause of death in patients with Fabry disease (FD). Echocardiography and cardiovascular magnetic resonance (CMR) have an established diagnostic role, but their prognostic value remains unresolved. This systematic review and meta-analysis sought to assess the prognostic implications of imaging parameters in FD.

Background Coronary artery bypass grafting (CABG) improves outcomes in patients with ischemic left ventricular (LV) dysfunction, but accurate patient selection remains critical. Late gadolinium enhancement (LGE) on cardiac magnetic resonance (CMR) imaging aids in assessing myocardial viability, a key predictor of surgical outcomes. This study aimed to evaluate the impact of myocardial viability on postoperative outcomes in patients undergoing CABG.
