The effects of recent Covid-19 pandemic on this planet must be viewed with a wise eye and we should learn that human beings are interconnected chains, and that ignoring the laws of existence will undoubtedly continue with reflections similar to the way we are today. Although the community of heart surgeons is not at the forefront of the treatment of this epidemic, they are ready to rush to the aid of other colleagues if necessary. The aim of preparing this protocol is to prioritize cardiac surgery procedures, maintain blood and blood product reserves and provide the appropriate care for patients while taking precautions for the safety of medical staff. The general recommendation in this first version of protocol is to postpone all elective cardiac surgeries and perform emergent and urgent cases according to suggested personal protection strategies for Covid-19.

Given the nature of heart disease and the importance of continuing heart surgery during the pandemic and its aftermath and in order to provide adequate safety for the surgical team and achieve the desired result for patients, as well as the optimal use of ICU beds, the medical team, blood, blood products, and personal protective equipment, it is essential to change the usual approach during the pandemic. There are still a lot of evidences and experiences needed to produce the perfect protocol. Some centers may have a special program for their centers during this period of epidemics that can be respected and performed. Generally, in pandemic conditions, the use of non-surgical approaches is preferred if similar outcomes can be obtained.
