Dr Nagy Mickhael has pledged to fund an angiography suite to be located in the General Hospital so that heart conditions can be diagnosed in the Island.
The team he says he has recruited includes Professor Ken Taylor, professor of cardiac surgery at Imperial College, London, and chief of cardiac surgery at Hammersmith Hospital, and Dr Peter Bourdillon, a UK cardiological government adviser.
Dr Mickhael says that having the suite locally would save the taxpayer £250,000 a year and would encourage more people to come forward for the potentially life-saving tests.
And without a suite, he says, the Island will find it very difficult to recruit a high-calibre permanent cardiologist.
He adds that most heart patients and their families would much prefer to be treated in the Island.
