What Can Cause Echoing Knocking Sound In Head Along With Black Out?

Scared To start out, I was born with a three chamber heart. I have no right ventricle and my mitro valve has a moderate leak. Last Saturday, I blacked out while driving to work. I have not been able to hold food down for longer than an hour since then. I have also had a constant headache. On Tuesday, I lost the lower vision in both my eyes. On Thursday, I started hearing an echoing knocking sound in my head. I happens every few hours and it feels like my head is being split open. I was given a halter monitor for 24 hours Saturday after the black out and I have an MRI scheduled for today at 9:30am. I will not get results till Friday. Any idea what could cause all of this?

Hello , There are chances that there might be rhythm disturbance which can lead to extra beats or various arrythmia, which van transiently decrease the blood supply to the brain causing blackout like situation . A 24 hour holter will pick up any such irregularities in the heart rhythm which in most cases can be treated with medicine alone .
Also due to such rhythm disturbance and the dilation of the piper chamber of the heart because of mitral leak , causes stasis of blood in the dilated chamber leading to clot formation which can get dislodge in the brain particularly if any connection exists . This might be the explanation of your remaining symptoms
So a MRI of the brain is done , it will be able to detect any such problem .
The above mechanism are some common reason why tye symptoms occur ed ,
Finding the cause and treating it would be the way forward. Regards Dr Priyank Mody
