  • Director of the hypertrophic cardiomyopathy program at The Valley Hospital
  • Co-Chairman of AATS Foundation Research Committee
  • Chair of European Association of Cardiothoracic Surgical Sciences and Translational Research Task Force

What would you like patients to know about your approach to care?

I perform an individual assessment of each patient's pathology with bespoke treatment algorithms for each and every patient. I use the broad and comprehensive use of cardiac imaging to enhance diagnostic accuracy. I also perform dynamic testing on patients with HOCM prior to considering surgical intervention. I incorporate research into my daily clinical practice.

What inspired you to become a doctor?

My uncle and his work as a medical examiner showed me the consequences of poor medical judgment. Since then, I strive to provide each patient with the best possible analysis and planning for their particular cardiac condition

Patient Ratings & Comments


Comments are gathered from our patient satisfaction surveys.

Dr. Grau, as always, is superb. He spends time explaining things in simple terms for one to understand, not medical jargon that one has to go home and pull out a dictionary.
Dr Grau was outstanding Thanks!
I was impressed how Dr Grau really took the time to fully explain MY condition not just the concept of an aneurysm. He asked questions and listened to my responses. The teaching was very personalized to my lifestyle. He put me at ease.
