Leeds heart surgery death figures wrong, says cardiologist

Children's heart surgery was wrongly suspended at Leeds General Infirmary because of "incomplete" information, a senior doctor has said.
The unit was shut after the NHS medical director said data showed mortality figures were higher than expected.
But cardiologist Elspeth Brown said the data did not include all the operations, and that staff were confident in their clinical work.
