Ajax defender Daley Blind undergoes successful heart operation

Ajax defender Daley Blind has undergone a successful heart operation.

Blind, 29, who previously played for Manchester United, suffered from dizziness in his side's Champions League clash with Valencia this week, but continued playing.

Blind's procedure saw a subcutaneous implantable defibrillator fitted, Ajax said in a statement on Saturday.

"Daley Blind has been diagnosed with myocarditis," the statement read. "In the last few days, the centre-back has been the subject of thorough medical investigation after experiencing a short episode of vertigo during the match between Ajax and Valencia.

"It was decided to preventively place a subcutaneous implantable defibrillator -- a device that is inserted under the skin -- as a consequence of the procedure, which took place yesterday."

The club added that the defender would miss their January training camp in Qatar, saying Blind would instead remain in Amsterdam to recover.

"The most important thing is that I'm feeling good at the moment and trying to come back as soon as possible," Blind said.
