This review describes the current understanding of ICEF based on a literature search from 1980 to the present. ICEF are observed in 0.5 to 20 percent of fetuses, with an overall frequency of 5.6 percent. These small, discrete structures near the papillary muscles and chordae tendinae move in synchrony with the intraventricular valves.
31 sie 2023 · The chordae tendineae, otherwise called the tendinous cords, is a misnomer that refers to support structures that form a bridge between the cusps of the atrioventricular valves and the papillary muscles.
Echogenic intracardiac foci are thought to represent calcifications within the fetal papillary muscle, and may be the result of an aggregate of chordal tissues that have failed to fenestrate completely, enhancement of abnormal tissue, or a collection of fibrous tissue with increased echogenicity (13,14).
11 sie 2011 · Echogenic cardiac foci (ECF) are microcalcifications in the vicinity of papillary muscles, chordae tendineae or atrioventricular valves, detected in 3.7 to 5.6% of fetuses undergoing...
20 sie 2011 · What are echogenic intracardiac foci (EIF)? EIF are small, echogenic lesions seen (on sonography) inside the left or right ventricles of the fetal heart within the papillary muscles or chordae tendinae. These lesions are not attached to the wall of the ventricles.
28 sty 2021 · Combined with the tomographic imaging, chordae tendineae and papillary muscles can also be clearly shown. In addition, some atrioventricular valves structure abnormalities were successfully visualize using the real-time volume imaging with electronic matrix probe in our study.
12 mar 2020 · The atrioventricular heart valves (AHVs) are responsible for directing unidirectional blood flow through the heart by properly opening and closing the valve leaflets, which are supported in their function by the chordae tendineae and the papillary muscles.
