Extra heartbeats that begin in one of the heart’s two lower pumping chambers (ventricles).
This year, for our End-of-Year Giving campaign, MitoAction will highlight the programs and events that brought hope, support, and advocacy to our community. It’s a full-circle moment, a chance to reflect on all we’ve experienced together, learn from it, and set the foundation for a strong start to 2026.
