I often hear patients say, “Doctor, I came here to have the surgery, why did those who came later than me have the surgery and I haven’t had it yet?” Other patients want to ask the doctor to schedule the surgery according to the time their children take off from work. These are inappropriate. We say that the timing of surgery requires comprehensive consideration and is one of the important factors for the success of surgery. We often say to patients and families, “which end do you think is cost-effective when you stay an extra week before surgery to adjust your medication and then operate, and recover quickly after surgery, and when you come to the surgery in a hurry before adjusting well and recover poorly after surgery?” The reasoning behind this will be understood by everyone. Some patients with valve disease already have heart insufficiency or even heart failure when they come to the hospital, and they need to make adequate drug adjustments before surgery after hospitalization to improve heart function and increase the heart’s reserve capacity so that the heart is in the best condition to meet the surgery, thus improving the safety of the surgery, and this adjustment takes a certain amount of time. Some patients with valve disease, on the other hand, have good heart function and do not need too much preoperative medication adjustment, and can be scheduled for surgery after perfecting the admission examination with no abnormalities. The surgeon will choose the most reasonable time to perform the surgery according to the patient’s condition and hopes that the patient will be patient and actively cooperate.
