heart specialist in Louisville

Anybody have any knowledge of or experience with a good heart specialist in Louisville? There's one who's supposed to be one of the very best in the country in Indianapolis, but surely Louisville must have some fine heart specialists. Yes?

I have heard a lot of good things about Cardiovascular Associates on Dutchmanns Lane. They also go offices all over the area. Here is their web site

I have no experience with them, but have heard about them through my job. Our only cardiology experence was with pediatric cardiologists when our son was a baby and had an enlarged heart and what turned out to be a innocent heart murmer.

Usually the patient's primary care physican is the best resource for a referal.

Thanks Suzi. I realize one's primary physician is usually the best reference, but in this case I'm not sure the specialist in question (already met with) is the best choice.
