Four-time Italian prime minister Silvio Berlusconi will undergo heart surgery next week. <br /><br /> His doctors said he should make a swift recovery after having a defective aortic valve replaced. <br /><br /> The 79-year-old was admitted to hospital on Monday suffering from what his doctors called a cardiac deficiency. <br /><br /> “Berlusconi risked his life, he risked dying, yes,” said Dr Alberto Zangrillo. “He arrived in hospital in a condition that was very serious, very worrying. He was aware of that.”<br /><br /> The doctor said that for a man who wants to live to be 130, this is a very unpleasant jolt. <br /><br /> Zangrillo said there was a two percent risk of mortality linked to the procedure which was expected to last four hours.<br />
