Barbara Bush released from hospital

The 84 year old, who is married to former U.S. president George Bush Sr., was admitted to The Methodist Hospital in Houston, Texas in February (10) after experiencing shortness of breath.

She underwent the operation on 4 March (10) after doctors detected a hardened valve in her heart, which if left untreated can result in heart failure and death.

According to a statement released from the hospital, doctors believe she may have suffered a mild relapse of Graves disease since the surgery – a thyroid condition for which she was first treated in 1989.

The former First Lady, mother to former U.S. leader George W. Bush, was discharged on Wednesday (31Mar10).
