Former Chelsea boss Maurizio Sarri undergoes successful heart surgery after rhythm disorder diagnosis

Lazio released an official statement regarding their coach’s condition: “SS Lazio announces that coach Maurizio Sarri, following a diagnosis of atrial fibrillation, underwent transcatheter ablation surgery using PFA technology at the Policlinico Tor Vergata.

“The operation was performed by Professor Andrea Natale, an international pioneer with over 30 years of experience in treating this condition, and was successful. The club’s medical director, Dr Italo Leo, was also present. The coach will resume regular management of the team in the coming days.

“SS Lazio and the coach thank the Policlinico Tor Vergata and Professor Natale’s team for their professionalism and the high quality of care provided.”

Atrial fibrillation (AFib) is an irregular and often rapid heart rhythm, classified as an arrhythmia. The condition can increase the risk of blood clots, stroke, heart failure and other heart-related complications.

Sarri’s successful surgery comes as a relief for Lazio, who are currently eighth in Serie A with 24 points, three behind sixth-placed Como in the race for European qualification.

The 66-year-old has spent most of his career in management, rising to prominence during his spell at Napoli between 2015 and 2018. He later coached Chelsea for one season, winning the Europa League, before moving on to Juventus and then Lazio. Sarri left the Rome-based club in March 2024 but returned in June 2025 on a two-year contract.

Lazio’s recent form has been unconvincing, with just one win in their last five Serie A matches and no game in that run featuring more than one goal scored. They face a demanding schedule ahead, with matches against Napoli on 4 January, Fiorentina on 8 January and Verona on 12 January, before a brief break ahead of their clash with Como on 20 January.
