Ventricular septal defect intracristal type is generally minimally invasive, but it should also be combined with the degree of the defect. The specific situation suggests that the patient further go to the hospital for detailed examination to clarify the treatment plan. Patients with intracristal ventricular septal defects have a small defect and a small shunt. Patients with small defects and small shunts usually do not have obvious clinical symptoms, and can usually choose minimally invasive surgical interventions for intracristal ventricular septal defects under the advice of their doctors, and most of them can be successfully blocked, but long-term efficacy of the treatment requires patients to follow up on a regular basis. Patients with large defects and high fractional flow may be associated with developmental disorders, palpitations (rapid heartbeat, often accompanied by panic), fatigue, panic attacks, susceptibility to respiratory infections, and in severe cases, heart failure, which is usually treated with open-heart surgery. Open heart surgery is usually performed by making an incision in the middle of the sternum, exposing the patient’s heart, using a stopping fluid to keep the patient’s heart in a state of stopping, and then making an incision into the pericardium to expose the defective ventricular septum, and then repairing the defect, and then starting to infuse the cardiac resuscitation fluid to make the heart start beating again after the repair is completed. In daily life, patients with ventricular septal defects should avoid high-intensity exercise, eat a light diet, get enough sleep, and eat more fruits and vegetables, such as spinach, tomatoes, apples, and so on. Patients with ventricular septal defects should always observe the changes in their body, and if they have any uncomfortable symptoms, they should consult a doctor in time and take treatment according to the doctor’s instructions, so as to avoid delaying the condition.
