I am a 47 year old male who had an 18mm ASD repaired using a 22mm Amplatzer device a little over 7 months ago. Good news: device is in place upon echo, with no intracardiac shunt. Bad news: I experience dizziness on standing up from a sitting (but not from a lying down) position; dizziness that makes me feel that loss of consciousness will surely follow, and tire easily. I have only fainted once, 3 weeks following the transcatheter closure - due to prescription of metoprolol that caused bradycardia, that was later discontinued (and symptoms abated). As a child fainting was common for me, but it abated, and I was never diagnosed with ASD until I turned 46.
Comparison of the echo reports from one month prior to the closure to 7 months post closure shows two things that concern me: (i) the post-closure report states "Spectral dopler shows impaired relaxation pattern of LV diastolic filling (grade 1)" - the pre-closure report read "Spectral dopler shows normal pattern of LV diastolic filling"; and (ii) the E/A ratio post closure is 0.67, with mitral valve deceleration time of 222 msec. The E/A ratio pre-closure was 1.59, and MV decel time 248 msec.
There appears to be some diastolic dysfunction post closure; ought not the E/A ratio be > 1? (1) Is this normal considering the operation, and time since? Did closure cause this? (2) Will I progress (deteriorate) to "grade 2", then "grade 3"? (3) Are my syptoms related to the difference in diastolic function? (4) Is there anything that can/should be done nutitionally/pharmacologically, etc., to prevent futher deterioration and/or improve my symptoms?
Be happy to provide other numbers; can't think right now which would be helpful. Many thanks.
