I was just told I have a moderate leaky valve and was wondering if I am OK to fly? Prior to this I flew on April 9 end ended up in emergency in the U.S. with 2 bilateral PESSOA on my lungs. I was put on blood thinners and then had the Echocardiogram done which found the leaky valve. I'm supposed to fly to Colorado on Sunday and will be spending 4 days in the mountains. Is my health at risk if I go? I'm am a 52 Yreka old female in otherwise good health with incredible blood work.
