The Countess of Wessex opened a new cardiac arrest unit on Wednesday, specially designed for younger patients. The money for the unit was raised by Wessex Heartbeat, of which Sophie is the Royal Patron.
Sophie met with patients and family members at the new ward in Southampton, where she also unveiled a plaque.
The unit cost £500,000 and will help young patients who suffer from lifelong heart conditions, providing better surroundings for patients and families.

At the Southampton unit, Wessex Heartbeat helps support 20,000 patients annually, including 1,000 babies and children born with congenital heart defects. This new ward will focus on 16 to 30-year-olds who are receiving treatment. It features a kitchen, a communal area, and a quiet room.
Sophie's royal seal of approval comes just over a week after the Countess celebrated her 50th birthday, for which she unveiled a new official portrait.

She later marked the day by carrying out two public engagements with her husband Prince Edward, attending the engagements in support of The Queen's Diamond Jubilee Trust and charity Tomorrow's People.
The Countess was greeted by royal fans and well-wishers as she arrived at the Tomorrow's People Social Enterprises , where the Countess was then presented with a birthday cake by a former Tomorrow's People client who now works at a local bakery and flowers from the charity's flower stall.
After their visit the royal couple proceeded to The London School of Hygiene and Tropical Medicine to see demonstrations of the Avoidable Blindness Programme of The Queen Elizabeth Diamond Jubilee Trust.
