Yankees star CC Sabathia underwent heart surgery earlier this month ... but New York GM Brian Cashman says, thankfully, the pitcher is expected to be OK.
"We are thankful that CC was smart enough to convey his symptoms to our medical staff ... We are also encouraged that the procedure CC underwent was performed as planned."
Sabathia reportedly needed an angioplasty -- a procedure where docs unblocked an artery in the former ace's heart -- after experiencing acid reflux, heartburn and other symptoms.
It's good news for the pitcher that he caught the signs early .
