I live in that area but drive to the Med Center for my cardiologist visits. That said, if you don't want to travel, call the Center for Advanced Heart Failure (my docs) and see if they can recommend someone at Memorial City. My electrophysiologist spends time between Med Center and Memorial City but I'm not sure if the cardiologists do the same. They've done a great job on my heart so I highly recommend that group.
Thanks for the replies everyone. BSD, I am going to call Dr. Kar's office and double check the referral thing. Thanks for offering to make a call. I might be in touch about that.
