ST LOUIS MO Cardiovascular Surgeon reccomendation for Type 1 Diabetic patient

My wife is a Type 1 diabetic for over 50 years and has had 3 heart attacks, so far all resolved with angioplasty and stents, however her cardiologist says she will require bypass surgery sooner or later (and it appears to be sooner). He was frank enough to say NOT HIM and NOT THIS HOSPITAL (outlying St Louis area) because of the special problems with the veins of someone with years of diabetes..

Hoping someone here with similar past diabetic issues that has required bypass surgery can recommend a cardiovascular surgeon at one of the major St Louis (MO) hospitals. For example Barnes (BJC). Missouri Baptist, St Lukes etc.

Thanks to anyone who loves their doc and can recommend him/her.
