New research highlights postnatal regeneration limits and pathological remodeling of the cardiac conduction system after myocardial infarction, uncovering mechanisms behind clinical arrhythmogenesis ...

During a severe heart attack many heart muscle cells die and are replaced by scar tissue to stabilize the heart wall. Connective tissue cells, known as fibroblasts (FB), are the dominant cell type in ...

Other hot topics included new data on LAAO and conduction-system pacing, plus the go-ahead for ablation in ASCs.

Cardiac arrest is defined as a sudden stop in heart function. Essentially, the pumping function of the heart is compromised, oftentimes due to a dangerous malfunction of the heart's electrical system.
