Compared with percutaneous interventional occlusion, minimally invasive surgical occlusion has the following advantages: 1. Wider range of surgical indications: percutaneous interventional occlusion is usually performed by inserting a catheter through the femoral artery at the root of the thigh to reach the heart, the catheter travels through too long a route and is limited in the areas it can reach, so it is not possible to treat the defects in special areas such as myocardial ventricular defects, whereas minimally invasive surgical umbilical occlusion is performed on the surface of the heart. Surgical minimally invasive umbrella occlusion is directly inserted into the catheter on the surface of the heart and guided by real-time ultrasound, so there is no restriction on the surgical site. Safety has been greatly improved: for interventional occlusion, the most dangerous complications are loosening of the blocker, dislodging of the blocker causing embolism and malignant arrhythmia during the operation. If the above problems occur in percutaneous interventional occlusion, they often can’t be handled in time, resulting in serious consequences and even endangering patients’ lives, whereas minimally invasive surgical umbrella occlusion is relatively much safer. In the event of the above situations, direct cardiac surgery can be carried out under extracorporeal circulation immediately to take out the loosened umbrella occluder, and at the same time avoiding the threat of malignant arrhythmia on the lives of the patients. Reasonable treatment cost: Compared with percutaneous interventional blockade, minimally invasive surgical umbrella blockade is more inexpensive. 4, there is no potential damage: percutaneous intervention blockage is usually done under the supervision of X-ray, in the process of operation, the patient will receive a long time, a large number of X-ray irradiation, which is potentially harmful to the patient’s health. Surgical minimally invasive umbilical occlusion is done under the guidance of real-time ultrasound, and there is almost no problem of radioactive damage. Compared with the traditional intracardiac direct vision surgery, minimally invasive umbrella plugging surgery also has a number of advantages: 1, small trauma, less bleeding: minimally invasive umbrella plugging surgery usually only need to make an incision of 2-3cm below the sternum, small wounds, good concealment, and do not need to completely open the chest, the trauma is significantly smaller than the traditional surgery; and minimally invasive umbrella plugging surgery surgery time is short, the amount of bleeding is very small, usually do not need to have a blood transfusion, which avoids the problem of blood transfusion infection, which is a concern for most of the patients. The patients are worried about the problem of blood transfusion infection. 2.No extracorporeal circulation, fast recovery: traditional endocardial direct vision surgery requires the assistance of extracorporeal circulation, although most of the patients who experience extracorporeal circulation can return to normal, but to varying degrees there are still abnormal physiological reactions, such as increase in interstitial fluid, thrombocytopenia, hemolysis, fever, hepatic and renal insufficiency, bleeding abnormality, and so on. Minimally invasive umbrella occlusion does not require the assistance of extracorporeal circulation, thus avoiding these harmful reactions. Moreover, patients undergoing minimally invasive umbrella occlusion surgery recover quickly, usually only need to be observed in the guardianship ward for 24 hours before being transferred to the general ward, whereas patients undergoing intracardiac direct visualization surgery can be observed for at least 48 hours. 3, the efficacy of the exact, less postoperative complications: minimally invasive umbrella plugging is completed under the guidance of real-time ultrasound, during the operation can be observed through the ultrasound surgical effect, timely adjustment, until the defect is completely blocked. The traditional endocardial direct vision repair has the possibility of residual leakage or conduction block caused by improper suturing, which is not easy to detect during the operation. Therefore, minimally invasive umbrella occlusion has obvious advantages in terms of therapeutic effect.
