3D printing gives pediatric heart surgery a boost

Researchers in the U.S. have created hundreds of individually tailored 3D-printed cardiac models to facilitate presurgical planning for pediatric heart disease. Using these models has helped lower operating times and reduce costs, according to a new article published in 3D Printing in Medicine.

Heart valve-tracking algorithm boosts viability of 4D MRI

An automated heart valve-tracking algorithm halved the amount of time and variability involved in blood-flow quantification with 4D MRI, according to an article published online October 30 in Radiology. The improved efficiency may help convince clinicians that cardiac 4D MRI is useful for assessing valvular heart disease.
