The Fontan process is obtainable to kids born with extreme coronary heart defects, permitting the kid to dwell with only one pumping coronary heart chamber as a substitute of two.
MCRI Dr Chantal Attard mentioned though the operation could not utterly ‘repair’ the center, most have been in a position to dwell properly into maturity and have comparatively regular lives. However she mentioned those that have the process have been at an elevated danger for blood clots.

Dr Attard mentioned the analysis confirmed for sufferers who endure Fontan surgical procedure, and would not have extra blood clotting danger elements, aspirin ought to be supplied over warfarin.
She mentioned given the necessity for normal INR monitoring of warfarin, a shift to aspirin would even have a value profit to the affected person and the healthcare system.
About 70,000 publish Fontan sufferers are alive right now, with this quantity anticipated to double inside 20 years.
Carley Clendenning’s son Lachie, 7, had the Fontan process two years in the past after being born with one coronary heart ventricle.
She mentioned the aspirin findings have been a reduction because the remedy was a lot simpler to handle and would profit different households whose kids required the process in future.
“Lachie has been taking warfarin ever since his surgical procedure and there are issues you must carry on high of with this remedy,” she mentioned.
