Describe some of your professional highlights.

Some of my professional highlights are as follows:

  • 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
