Focused cardiac ultrasound

In the fetal cardiac ultrasound examination, standard cardiac cycle (SCC) recognition is the essential foundation for diagnosing congenital heart disease. Previous studies have mostly focused on the detection of adult CCs, which may not be applicable to the fetus. In clinical practice, localization of SCCs needs to recognize end-systole (ES) and end-diastole (ED) frames accurately, ensuring that every frame in the cycle is a standard view. Most existing methods are not based on the detection of key anatomical structures, which may not recognize irrelevant views and background frames, results containing non-standard frames, or even it does not work in clinical practice...

Acute right heart failure (ARHF) arises when the right ventricle fails to pump blood efficiently to the pulmonary circulation. This inefficiency leads to a decreased blood supply to various organs. ARHF is a significant health concern, often leading to increased hospital admissions and being associated with a higher risk of mortality. This condition underscores the importance of effective cardiac care and timely intervention to manage its complications and improve patient outcomes. Diagnosing ARHF involves a comprehensive approach that includes a physical examination to evaluate the patient's fluid status and heart-lung function, blood tests to identify potential triggers and help forecast patient outcomes and various imaging techniques...

Cardiac ultrasound seeks to image the most dynamic environment in the body - the moving heart. Many modern ultrasound imaging techniques address the trade-off between spatial and temporal resolution using either narrow focused beams or with broad beam, synthetic aperture sequences that have been shown to suffer from motion artifacts. Retrospective Encoding for Conventional Ultrasound Sequences, or "REFoCUS", unifies the processing of these various geometric sequences, but the motion sensitivity of this approach has yet to be investigated...

Inferior vena cava assessment is a standard component of focused cardiac ultrasound, traditionally used to qualify intravascular volume status. In this case series, we demonstrate that pediatric focused cardiac ultrasound can also diagnose inferior vena cava thrombi and masses, while distinguishing them from a potentially benign smoke-like artifact.

Point-of-care ultrasound (POCUS) is an accessible technology that can identify and treat life-threatening pathology in real time without exposing children to ionizing radiation. We aim to review current evidence supporting the use of POCUS by pediatric intensivists with novice-level experience with bedside ultrasound. Current evidence supports the universal adoption of POCUS-guided internal jugular venous catheter placement and arterial line placement by pediatric critical care physicians. Focused cardiac ultrasound performed by PICU physicians who have completed appropriate training with quality assurance measures in place can identify life-threatening cardiac pathology in most children and important physiological changes in children with septic shock...

The dorsal anterior cingulate cortex (dACC) is a critical brain area for pain and autonomic processing, making it a promising non-invasive therapeutic target. We leverage the high spatial resolution and deep focal lengths of low-intensity focused ultrasound (LIFU) to non-invasively modulate the dACC for effects on behavioral and cardiac autonomic responses using transient heat pain stimuli. N = 16 healthy human volunteers (6M/10F) received transient contact heat pain during either LIFU to the dACC or Sham stimulation...
