"Nebraska Medicine Introduces Innovative AFib Heart Procedure"

Nebraska Medicine has introduced a new heart procedure called pulsed-field ablation to treat atrial fibrillation (AFib), a condition where the heart beats irregularly. This procedure, approved by the FDA in December 2023, uses a hydrating electrical field to denature the tissue and make it electrically inactive, without the risks associated with thermal energy. Dr. Jason Payne, a cardiologist at Nebraska Medicine, highlights the safety and efficiency of this procedure, which allows patients to be discharged within a few hours and experience a quick return to normalcy. With the rising number of Nebraskans being diagnosed with AFib, the hospital aims to meet the demand for this procedure in a faster and safer manner.

"Identifying Potential Causes of Sudden Unexplained Child Deaths"

A new study has identified a potential cause of sudden unexplained death in children, pointing to a genetic mutation that affects the heart's electrical system and can lead to cardiac arrhythmia. The research sheds light on a previously unknown mechanism behind these tragic events, offering hope for improved understanding and potential preventive measures.

Light-based graphene 'tattoo' cures heart arrhythmia.

Researchers have developed a graphene "tattoo" implant that can treat cardiac arrhythmia with light. The implant is thinner than a single strand of hair and functions like a classical pacemaker. It softly merges with the heart to simultaneously sense and treat irregular heartbeats. The implant is thin and flexible enough to conform to the heart's delicate contours as well as stretchy and strong enough to withstand the dynamic motions of a beating heart. The technology is optically transparent, allowing the researchers to use an external source of optical light to record and stimulate the heart through the device.

Scientists Overcome Roadblock to Human Heart Regeneration

Scientists at the University of Washington School of Medicine have used CRISPR-based genome editing to create stem cells that do not cause dangerous arrhythmias, a major complication previously hindering stem-cell therapies for injured hearts. The team created a new line of cells called “MEDUSA,” which engraft in the heart, mature, and integrate into heart muscle without generating dangerous heart rates. This breakthrough could pave the way for safe and effective stem cell therapy for heart regeneration.
