A verdict of “medical misadventure” has been recorded in the death of a woman with an “unusually healthy” heart after she suffered a cardiac arrest while undergoing a routine procedure at a dental clinic in Dublin two and a half years ago.

An inquest into the death of Margaret O’Doherty, 72, five days after becoming ill during surgery for seven dental implants at the Dublin Specialist Dentistry in Sandyford heard evidence the most likely cause of her sudden cardiac arrest was the effect of a sedative drug, midazolam, used during the surgery.
