question: Hi. I am 36, Male and have a metallic aortic valve in my heart already for 22 years. Recently I have experienced loosing sense on left or right of my body or face few times in last two weeks. It just starts suddenly including double vision and losing my body balance, but my blood pressure stays above 115. It goes away after 1 or 2 hours all by itself. Could that be due to my heart craft mulfunction or it is brain related?
