During the procedure, what was used to deliver cardioplegia?

The approach of delivering cardioplegia through the aortic root via a retrograde method is widely recognized in cardiac surgery. This method involves administering a cardioplegic solution into the aortic root, allowing it to flow backward through the coronary arteries and into the heart muscle. It is especially effective in achieving rapid and uniform cooling of the myocardium, which reduces its metabolic needs and protects it during surgery.

Using this method helps ensure that the cardioplegic solution reaches the areas of the heart that require protection from ischemia. Additionally, when the retrograde route is employed, it can facilitate an optimal distribution throughout the myocardium, contributing to effective cardiac preservation during procedures like coronary artery bypass grafting or valve replacements. This technique is particularly beneficial due to its ability to minimize the risk of damaging coronary vasculature while still achieving the desired effect of cardioplegia.

The retrograde delivery method is often preferred for its efficacy and ease of use compared to other techniques, which may not provide the same level of myocardial protection or may require more complex setups.
