While there is significant awareness regarding droplet and contact transmission, aerosols are generally underestimated as a potential mode of transmission of SARS-Cov-2 infection. With the gradual resumption of cardiac surgical activities, the cardiac surgical operating room will become an important potential source of infection to the cardiac surgeon and other healthcare workers participating in the operation. There is also diminished awareness about the different aerosol generating procedures (AGP) in the cardiac surgical operating room. In this mini-review we intend to highlight the various aerosol generating procedures that are common in cardiac surgery. This will help increase the awareness among surgeons to AGP. A practical approach to taking preventive measures have also been discussed.
