Bouwmeester was rushed to a Southern California hospital ... where he later had surgery to place an Implantable Cardioverter Defibrillator (ICD) in his chest to prevent future issues.
In his first public statement since it all went down, Jay said he's recovering nicely ... and thanked everyone for their well wishes.
"I would sincerely like to thank all of the trainers from both the St. Louis Blues and Anaheim Ducks, as well as, all of the first responders, the Anaheim medical staff and the team at the UCI Medical Center for their quick actions on Feb. 11."
Jay continued, "Our family has felt the support of the entire National Hockey League family and the city of St. Louis during this time. We have all been greatly comforted by your genuine concern."
"On Sunday evening, I returned to St. Louis and I am on the road to recovery."
