Former WCW champion Vader underwent yet another heart surgery on Tuesday, his second one since March 26, this time to correct an irregular heart beat.

Vader was suffering from atrial fibrillation, the irregular heartbeat condition that can lead to blood clots, stroke, heart failure and other heart-related complications. Vader tweeted that the surgery took care of the AFib and is now recuperating in hospital.

In late March, Vader underwent open heart surgery and while it was successful, doctors found damage worse than they expected. Before the surgery, his heart was functioning at 30% only and full surgery was the only way forward.
