Lazio boss Maurizio Sarri has undergone successful heart surgery after he was diagnosed with atrial fibrillation, the club has confirmed.

The 66-year-old had a catheter ablation operation in Rome on Monday to treat his condition, which caused an irregular heartbeat and increases the risk of suffering a stroke.

Sarri is expected to return to work in the next few days, with Lazio assistant coach Marco Ianni overseeing training in his absence. 

The Biancocelesti confirmed the procedure, performed by Professor Andrea Natale, was "carried out with a positive outcome", while club doctor Italo Leo was also present.

Sarri, who previously led Lazio between March 2021 and June 2024, returned to the club for a second stint in June.

The former Napoli boss could return to the dugout when the Biancocelesti host the Partenopei at Stadio Olimpico on Sunday.
