With the continuous development of medical technology, most of the common congenital heart diseases can now be treated radically by interventional treatment without surgery. When patients are seen in large cardiac centers nationwide (many local hospitals have only one domestic device to choose from), the physicians often seek the patients’ opinion on whether to use domestic or imported devices before hospitalization or surgery, and often fail to make a reasonable and appropriate choice due to the patients’ lack of relevant knowledge and susceptibility to customary views. It should be noted that both domestic and imported devices are subject to strict inspection and approval procedures by the State Food and Drug Administration (SFDA) before they can be used in hospitals, and generally do not have quality problems and are qualified and effective. The correct choice should be according to the needs of different conditions and combined with their own economic situation with the help of doctors reasonable choice. Now, the specific description of the choice of devices for precordial disease is as follows: 1, atrial septal defect blocking device selection: the current clinical use of atrial septal defect blocking device is divided into domestic and imported two categories, domestic devices and imported devices are basically the same material and design, there is no significant difference in efficacy, imported products are generally produced by the United States AGA, due to import tariffs and other relations, the price is slightly higher, the specific choice of which are It is possible to choose any kind of device, generally doctors do not recommend it, patients can choose according to their own habits. 2, ventricular septal defect blocking device selection: At present, more than 95% of the domestic clinical use of ventricular septal defect blockers are domestic devices, because in clinical practice it is found that the domestic design of blockers is more suitable for most Chinese defect form, and the efficacy is better; some imported blockers were used in the early stage, and then most of them were used domestic blockers, and only for a very small number of special cases will the use of imported blockers be considered. Only for very few special cases will imported blockers be considered. Therefore, in our hospital, we generally do not ask patients whether to use domestic or imported devices when performing ventricular septal defect blocking surgery, but only inform patients and their families whether to consider using imported devices when encountering special circumstances during surgery. 3, the choice of devices for arteriovenous catheter occlusion: domestic PDA blocker and imported PDA blocker are basically the same material and shape, but because the domestic devices are improved for the characteristics of the high proportion of large and thick PDA in our patients, the effect of blocking large and thick PDA is better, so currently more than 90% of the domestic clinical use of PDA blocker is domestic devices, only for some low weight children Only for some low weight children and some cases with special morphology are imported blockers considered, which can play a special effect. Before interventional occlusion of patent ductus arteriosus, a reasonable choice of occluder can be made according to your own situation and doctor’s opinion. 4, pulmonary valve stenosis balloon dilatation device selection: at present, there are also two types of clinical balloons, domestic and imported for choice, imported balloons are expensive, the effect is not much different, but the convenience of operation imported balloons are slightly better, patients can choose the balloon according to their own situation combined with the doctor’s opinion.
