Congress President Sonia Gandhi on Monday left for the US for medical check-up.
Accompanied by her daughter Priyanka, she left in the afternoon, official sources said.
Gandhi, 66, who had undergone a surgery in the US for an undisclosed ailment on August 5, 2011, had flown there for a check-up in February and again on September 2 last year.
The Congress President was admitted to AIIMS last Monday after she complained of chest pain and exhaustion in the Lok Sabha during a discussion on Food Security Bill when it was in the last stages of adoption.
She was discharged from the hospital after she spent five hours undergoing various tests. Gandhi, who had cough and headache, had felt uneasy in Parliament after taking medicines.
