What could be the reason for uneasiness and tiredness in a heart patient?

Hello,

Welcome to icliniq.com.

I have reviewed your health query and can understand you are worried about your wife's cardiac issues and recent symptoms. She is having issues with one of the valves of the heart. It is named the aortic valve and is normally made of three leaflets or cusps. In 1% to 2% of the population, the aortic valve is made of only two cusps. One cusp is missing by birth. It causes issues with the function of the valve. Initially, it is not so noticeable but after a prolonged period of time, the valve gets to have some other problem, the symptoms appear. The other issues the has happened over time with the aortic valve of your wife is that the leaflets of the valve have gone stiff (hardened). This causes the heart to push with a lot of force in order to push blood against hardened or stiffened aortic valve. The aortic valve is situated at the exit point of the heart where the blood leaves the heart to run throughout the human body. Otherwise, her heart is working okay. She needs proper management of the issue by a cardiologist. The cardiologist may go for another type of echocardiography called TEE or transesophageal echocardiography that gives more details compared to a 2D echocardiogram. He would be in a better position to decide how to proceed. In some cases, we need to surgically replace the defective aortic valve. Hope it helps. Please feel free to ask more if you need further assistance.
