A classic car mechanic from Wimbledon says it is "nothing short of a miracle" he survived a freak accident which left his heart punctured in three separate places.
Mark McQuoid was helping a friend re-fit a private gym in Putney when a power tool backfired into his chest.
The 54-year-old was left with a coin-sized hole leading straight to his heart.
The father-of-two was treated by specialists at St George’s Hospital, Tooting, who made the decision to cut his chest open and carry out an emergency resuscitative thoractomy.
Doctors later told him he is the only to person survive the operation in the 15 times they have attempted it.
London Live's Reya El-Salahi has been to meet Mr McQuoid at his home.
