Napoli have said Scott McTominay’s heart surgery “was a complete success” and expect the Scotland midfielder to resume training this month.

The 29-year-old’s ablation procedure – a minimally invasive operation to correct irregular heart rhythms – took place at Spire Manchester Hospital on Tuesday morning.

McTominay was substituted after 56 minutes of Napoli’s 2-1 Serie A defeat by Como on 30 August.

A mild benign arrhythmia was discovered, prompting the corrective treatment.

Napoli, who said in statement, external that “McTominay will rest for two weeks and then resume training”, had expected the former Manchester United player to return to action after the international break in early October.

When his heart issue was announced, McTominay posted on Instagram: “See you soon Napoli. I won’t take long.”

Sebastien Pocognoli’s first four games as Scotland head coach – home and away against Slovenia as well as matches with North Macedonia and Switzerland in the Nations League – are scheduled for the end of September and early October.

According to the NHS,, external an arrhythmia is when the heart beats too quickly or too slowly, or the heartbeat is not steady.

The British Heart Foundation explains, external a cardiac arrhythmia ablation involves using heat or cold energy to create tiny scars in the heart to block faulty signals and restore a typical heartbeat.
