Chamber size changes over time
Chamber size changes over time
I suppose you posted that twice because you didn't think I would get it the first time, Kim...
My cardiologist said very plainly that if I experienced angina, I was to quit what I was doing until it went away. Angina generally means your heart is having trouble coping. It's working too hard, or not getting enough oxygen. With most aortic issues, exercising it further at that point is not helpful, and may be harmful.
That does not mean that you should reside upon your derriere for the duration. Walking on level ground is good: movement is essential to life. Just don't push it when you feel the angina.
James (Shine On Syd) related a salient point when referring to the chamber sizes. The point is
change over time. You can likely deduce the rate of change from your consecutive echo reports (your doctor is required to provide your records at your request, although he can charge a moderate copying fee). And don't just go by the "normal" ranges, if they're printed on the report.
For example: "normal" range for Left Ventricle (LV) End Diastolic Diameter is 3.5 cm to 5.7 cm. My oldest echo puts mine at 3.5 cm. The last one before surgery puts it at 5.7 cm. Both readings are within the "normal" range, but the
change was not. That is the type of thing you may spot that could easily slide by your cardiologist, who may just see "normal," with a cursory inspection of only your most current echo.
Also, significant regurgitation or stenosis is usually accompanied by a great deal of calcification of the valve. The measurements of valve opening are a computed estimate, and frequently neglect the effects of the mineral deposits.
Even more importantly, these symptoms indicate that the valve itself is no longer flexible, a fundamental requirement for its task. That is usually captured in the mean gradient (force of flow) required to push the blood through the valve during the pump (beat). The peak gradient indicates the fluid pressure the heart has to develop to force the creaky valve open at the beginning of the beat.
Case in point: my surgeon and interventional cardiologist both originally felt my valve was in the grey area for surgery. However, when he got to the valve, the surgeon said he found that two of the leaflets were completely immobilized, and the third barely moved. He does over 1,000 open heart surgeries a year, and he said without blinking that he really didn't know how I was getting blood through it at all. He looked a bit chagrined
The gradients may not show as much information with regurgitation, especially if stenosis is not strong, but that may just mean that the valve is glued
open, instead of closed.
Uh-oh. I've gone on long, and risk boring everyone. Ross will be eyeing my disk usage again.
Best wishes,
