The test was administered by the same doctor who performed surgery to repair a damaged artery in Gee's pitching shoulder six weeks earlier.
"The visit in St. Louis couldn't have gone better," Gee told ESPNNewYork.com. "He said I look great."
Because he underwent the angiogram, Gee will wait until next week to begin throwing and full workouts.
Gee is expected to have no lingering issue when the Mets report for spring training in February.
"I don't foresee a return this year, but I'm not trying to put a timetable on anything," Gee said. "I just want to begin throwing and see how I progress from there."
