Doctors have determined that California Angels left-hander Fernando Valenzuela won't need heart surgery despite a slight heart abnormality.
An angiogram performed on the 30-year-old pitcher Tuesday revealed no narrowing or hardening of the arteries.However, Dr. Larry Santora, who performed the diagnostic procedure at St. Joseph's Hospital in nearby Orange, said that when Valenzuela's heart beats, the artery that supplies blood to the heart periodically crimps.
Valenzuela underwent the angiogram after a recent treadmill exam showed a possible heart irregularity.
Santora said Valenzuela's condition would be re-evaluated "from time to time," the Angels said.
Valenzuela will take medication for the next week and will repeat a treadmill test at that point, the Angels said. After the next test, he should be able to return to the team.
The pitcher was placed on the 15-day disabled list Thursday - a day after his most recent start for the Angels - and is eligible to be activated June 28.
Valenzuela is 0-2 with a 12.14 ERA in two starts with the Angels. He signed a major league contract with them June 4.
