I underwent open heart surgery. Dr Bittar was extremely informative pre-op as all of my queries were answered and my worries were put to rest. He regularly came to check on me post-op and was very thorough and professional in his work. The aftercare in the CICU was very professional as well. I have had 2 further check ups post-op and both were carried out in professional and timely manner. I highly recommend Mr Bittar for anyone who is looking at any cardiac surgery.
