Thanks for your response. My Mom initially had the valve replaced in 2012 & it has narrowed again. After speaking at length with her cardiologist again, she's decided to take a "wait & see" approach. Since she's not having any major symptoms, mainly just fatigue, her cardiologist felt this was a reasonable choice. At age 82, quality is more important than quantity when risk of surgical complications are likely very high.

Her cardiologist had mentioned TAVR which also would require mega doses of blood thinners.
