Isolated small ventricular septal defects in utero: HDlive Flow with spatiotemporal image correlation and HDlive Silhouette case study

To demonstrate shunt flow through small ventricular septal defects (VSDs) using HDlive Flow with spatiotemporal image correlation (STIC) and HDlive Silhouette. Four cases of isolated small VSDs were evaluated using colour Doppler, and HDlive Flow with STIC and HDlive Silhouette. HDlive Flow with STIC and HDlive Silhouette can improve the ability to depict shunt flow through small VSDs compared with colour Doppler. This technique provides information on spatial recognition of the shunt flow through isolated small VSDs in real time.
