Technical Field
The invention relates to the field of cardiovascular medical treatment, in particular to an adjustable heart defect plugging device.
Background
Cardiac defects include Atrial Septal Defects (ASD) and Ventricular Septal Defects (VSD), which means that the atrial septum/ventricular septum is abnormal in the process of generation and absorption and is not normally closed, so that a through hole is remained between the left atrium and the right atrium/the left ventricle, and generally an occlusion operation is required for treatment. The main apparatus used in the occlusion operation is an occluder which can be implanted in an interventional way; the traditional occluder is generally in a double-disc thin waist-shaped structure (comprising a head umbrella disc, a tail umbrella disc and a waist part positioned between the head umbrella disc and the tail umbrella disc), and intracardiac shunt is prevented by the clamping action of a left umbrella disc and a right umbrella disc on the residual edge tissues of the atrial septum.
For normal people, the blood pressure in the left heart is higher than that in the right heart; the heart of a patient with heart defect is not normally closed due to the interval between the left ventricle and the right ventricle or the left atrium and the right atrium, so that the load of the heart is increased, the pulmonary circulation blood volume is increased, and finally pulmonary hypertension, arrhythmia and heart failure can be caused; if a common occluder is used for occluding the defective part of the heart, high pressure of the left pulmonary artery can be caused, namely, the partial defective patient can not tolerate the high pressure when the heart is completely closed.
