Unlabelled: Four-dimensional flow cardiovascular magnetic resonance (4D Flow cardiac MRI) is an advanced non-invasive imaging technology, and its derived kinetic energy (KE) blood flow parameters have been confirmed as a potential biomarkers for assessing ventricular hemodynamics. This review synthesizes details on the methodology, clinical significance, and current status of studies focused on quantifying KE parameters of the ventricle using 4D Flow cardiac MRI, providing an objective foundation for further exploration of the value of KE in cardiac diseases.
Study Type: retrospective.
Subjects: This review includes studies that utilized 4D Flow cardiac MRI in human subjects, focusing on the changes in KE parameters. Field Strength: 1.5T or 3T.
Assessment: A systematic review was conducted to assess the literature on the intracardiac clinical applications of 4D Flow cardiac MRI. In September 2024, searches were performed in PubMed, Web of Science, SCIENCEDIRECT, and Springer Link databases using the keywords "4D Flow cardiac MRI," "ventricular kinetic energy," and "intraventricular hemodynamics," covering a period of 10 years. The inclusion criteria for the literature were: (1) clinical trials with human subjects; (2) studies that addressed the value of 4D Flow cardiovascular magnetic resonance and its derived blood flow KE parameters in quantifying ventricular blood flow. The exclusion criteria were: (1) animal experimental studies; (2) non-English core journal articles. Out of the 195 articles screened, 62 studies met the criteria for the systematic review. The included literature comprised 26 (41.9%) studies on 4D Flow cardiac MRI technology and blood flow parameter research, and 36 (58.1%) clinical application studies. KE measurement using 4D Flow cardiac MRI is a promising tool for evaluating ventricular hemodynamics. It provides clinicians with deeper insights into the physiological and pathological dynamics of ventricular blood flow, from healthy states to disease.

Persistent systemic inflammation is associated with an elevated risk of cardiometabolic diseases. However, the characteristics of the innate and adaptive immune systems in individuals who develop these conditions remain poorly defined. Doublets, or cell-cell complexes, are routinely eliminated from flow cytometric and other immune phenotyping analyses, which limits our understanding of their relationship to disease states.

The detection of cardiac phase in ultrasound videos, identifying end-systolic (ES) and end-diastolic (ED) frames, is a critical step in assessing cardiac function, monitoring structural changes, and diagnosing congenital heart disease. Current popular methods use recurrent neu ral networks to track dependencies over long sequences for cardiac phase detection, but often overlook the short-term motion of cardiac valves that sonographers rely on. In this paper, we propose a novel optical flow-enhanced Mamba U-net framework, designed to utilize both short-term motion and long-term dependencies to detect the cardiac phase in ultrasound videos.

This study aimed to assess whether delivering Continuous Positive Airway Pressure (CPAP) through a Helmet interface (H-CPAP) reduces common carotid artery flow (CCAF), compared to breathing room air (RA) or using an oronasal mask (M-CPAP). This trial is an unblinded, randomized, controlled crossover trial. The primary outcome was CCAF, measured using Doppler ultrasound.

Importance: Outcomes in patients with diabetes after fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) using current-generation drug-eluting stents (DES) compared with coronary artery bypass grafting (CABG) are unknown.
Objectives: To investigate the relative treatment effect of PCI vs CABG according to diabetes status with respect to major adverse cardiac and cerebrovascular events (MACCE) at 3 years and to evaluate the impact of the SYNTAX score.
Design, Setting, And Participants: This is a prespecified subgroup analysis of the FAME (Fractional Flow Reserve vs Angiography for Multivessel Evaluation) 3 trial, an investigator-initiated, randomized clinical trial conducted at 48 centers worldwide.
