LATEST: The husband of actress Natascha McElhone died of a fatal heart condition, according to the results of a post-mortem examination.
Plastic surgeon Martin Kelly was found slumped on the doorstep of the couple's London home on Tuesday (20May08) night and died later in hospital.
The tragic news came just a day after they celebrated their 10th wedding anniversary.
Police initially treated Kelly's sudden death as unexplained, but a spokesman has now revealed the 43-year-old died as the result of a dilated cardiomyopathy - a condition where the heart becomes enlarged and unable to pump blood.
The 38-year-old actress, who is pregnant with their third child, has halted filming on hit U.S. show Californication to fly back to London from Los Angeles with the couple's two sons Theodore, eight, and Otis, five.
