.." Bob Foley, 45, can relax these days with the confidence of a man who has beaten, for now, a serious heart ailment. Foley's heart was recently diagnosed to have six blockages in surrounding arteries and he underwent a revolutionary new operation in Kingston to help alleviate the problem. The car- diology team at Kingston General Hospital used an American bom technique which sees a probe equipped with a small balloon type device placed into.arteries and in- flated to dissipate clots. Foley had the operation last Tuesday and was home in Belleville by last Thursday. •
