In a recent study, researchers from Japan tested a novel approach that involves injecting 'cardiac spheroids,' cultured from human stem cells, directly into damaged ventricles.

During atrial fibrillation, the heart's upper chambers beat irregularly and are out of sync with the ventricles.

Researchers in Christman's lab prepared the hydrogel with tissue from both the right and left ventricles of the pig hearts.

However, in nearly half of these patients, the extra help leads to an imbalance between the left and right ventricles, which can pose danger to the patient.

Ventricular arrhythmia, which occurs in the lower chambers of the heart or ventricles, is the leading cause of sudden cardiac death in the United States.
