Choosing to isolate the lungs away from the heart using sterile supplies is recommended as it greatly minimizes the risk of contamination during the recovery of heart valves. The lungs can harbor bacteria and other pathogens that pose contamination risks to the heart tissues. By using sterile supplies to isolate the lungs, the tissue recovery team creates a controlled environment that protects the heart from exposure to potentially harmful microorganisms.

In this context, recovering the heart after ensuring a sterile field around it is critical for maintaining the integrity and safety of the valves being harvested. Other choices may involve techniques or methods that do not specifically address the contamination risk as effectively. Employing sterile supplies as a barrier is a proactive measure in tissue recovery procedures, ensuring that the harvested material is of the highest quality for transplantation and other uses.
