News & Events

  • Paradigm Shift in Mitral Valve Repair

    New guidelines recommend mitral valve repair for asymptomatic patients with mitral valve regurgitation, allowing for comparable outcomes with faster recovery.


  • Dolly's Story: Getting Back on Her Feet

    Dolly Lakkis—a business owner, optician and competitive dancer—didn’t have time to be sick. When mitral valve disease started to affect the quality of her life, she turned to a team of specialists at the Corrigan Minehan Heart Center at Massachusetts General Hospital. Dolly’s doctors were able to repair her damaged heart valve with minimally invasive surgery that got her back on her feet—and back on the dance floor—as quickly as possible.
