Been flying within an airline for 12 years and a murmur was picked up last year.
Was told it would be fine and most probably benign.
Headed off for tests and they found I had a very leaky aortic valve. Sent all the stuff off from the tests to the CAA and have had a Multi Crew Limitation applied to the class one.
It will require surgery to replace the valve at some stage but the CAA have been brilliant and seem to want to mange the condition keep me flying rather than the other way around and have found all their 'experts' in Belgrano very practical.
