Same. Nobody really does neuro fellowships unless they want to stay at an academic place and make a name in a niche field or become department director. People do cardiac fellowships and might have a little leg up in the job market if a place needs a heart person, or the starting pay might be a little more from what I've heard. Big advantage here is you have TEE to offer. The fellowships that are ACGME accredited all give you a little something that most general people will shy away from: Peds you get NICU babies and 'sick' complex kids, hearts gets you TEE, pain gets you blocks and clinic exposure. Other fellowships include neuro, OB, regional, ambulatory, even 'advanced clinical'.
