Leaner Jansen ready to compete again for Dodgers in 2019
Kenley Jansen’s cardiologist had an unexpected suggestion for the Los Angeles Dodgers closer last fall.
After a recurrence of atrial fibrillation last August, Jansen expected to undergo surgery after the season, his second procedure in six years to address the issue. But even after examining Jansen, Dr. Koonlawee Nademanee told Jansen he was having a difficult time pinpointing which part of Jansen’s heart had caused the irregular heartbeat episode and suspected it was a combination of dehydration and the altitude in Denver that had been the main factors.
“For him, he didn’t even want to do that surgery,” said Jansen whose heart was shocked back into rhythm during the August episode. “He wanted me to go to Colorado and work out for a month to see if it would come back.
“He said go for a month, work out for a month and see if you get back into a-fib. … I said, ‘Naw, let’s do the surgery.’ ”
Jansen underwent the catheter ablation procedure in late November. Afterward, Nademanee told him that some very small veins near the site of his 2012 procedure had grown, were agitated by dehydration and were responsible for sending the irregular signals.
“‘Just go out and play,’ ” Jansen said Nademanee told him after surgery.
The whole experience made Jansen more aware of his health. He has dropped 25 pounds and lowered his blood pressure.
After throwing a bullpen session Wednesday, Jansen said his pitches seemed to have more life this spring than they did at times last season. The velocity on Jansen’s cut fastball dipped last year.
“I’ve got to prove everybody wrong,” he said. “That’s all I want to do.”
