Hi Laurie ~~ you're in Texas..!! Hip, hip, hooray.. I'm just down I35 from you about 45 miles..
Before I was old enough for Medicare, I was on the Texas High Risk Pool Insurance policy and one of the qualifying issues is an "artificial heart valve".
You can have a look at the website and see what your rate would be according to which deductible you prefer:
I was on it for about 5 years and it was with Blue Cross/Blue Shield.
