In a rare and highly complex cardiac procedure, Kolkata doctors have successfully implanted a permanent pacemaker in an elderly woman who had an artificial bicaval valve system, giving her a new lease of life.

It is a highly specialised treatment used in patients suffering from severe tricuspid regurgitation, a condition where a valve on the right side of the heart does not close properly, causing blood to flow backward, and congestive heart failure.

To the best of the doctors' and hospital's medical knowledge, this is the first such case in India and has been reported only once globally.
