Maltais.Simon@mayo.edu Clinical Profile


Simon Maltais, M.D., Ph.D., conducts research in heart transplantation, durable mechanical circulatory support, acute and temporary circulatory support measures, and translational-based heart failure research (stem cell therapy). Dr. Maltais specializes in minimally invasive cardiac interventions (robotic surgery) and has performed several surgeries on various conditions with these approaches.

Dr. Maltais is interested in how less-invasive approaches apply to the implantation of durable devices in patients with heart disease and hopes to investigate the application of stem cell-based therapy for myocardial recovery.

Focus areas

  • Advanced heart failure. Dr. Maltais specializes in the application of advanced heart failure therapies to patients with advanced heart failure and failure of optimal medical therapy. He is investigating the application of new technology as well as less invasive approaches for left ventricular assist device (LVAD) and durable device implantation, including off-pump surgery.
  • Minimally invasive cardiac surgery. Dr. Maltais has established a reputation in minimally invasive cardiac intervention, including mitral surgery as well as aortic valve replacement. He also performs robotic mitral valve repair and translational and stem cell-based research.

Significance to patient care

Dr. Maltais hopes that through his research, better technology and a better understanding of advanced heart failure therapies, the applications of novel therapeutics for patients with heart failure will be increased.
