Diagnosis and interventional treatment scope of congenital heart disease, structural heart disease and pulmonary hypertension: 1, congenital heart disease interventional treatment (transcatheter atrial and ventricular septal defect, oval foramen insufficiency; arteriovenous catheter insufficiency; aortic sinus aneurysm rupture; coronary arteriovenous fistula; pulmonary arteriovenous fistula occlusion; body-pulmonary collateral occlusion). 2, interventional treatment of heart valve disease (percutaneous balloon pulmonary valve; mitral valve; aortic valvuloplasty; percutaneous mechanical valve leak and stent valve leak closure; percutaneous aortic valve, pulmonary valve stent valve implantation) 3, interventional treatment of pulmonary vascular disease (acute and chronic pulmonary hypertension – idiopathic and secondary pulmonary hypertension drug therapy and interventional treatment; acute pulmonary embolism – interventional thromboablation; Thrombolytic therapy and anticoagulation; stent implantation for pulmonary artery stenosis) 4.Interventional treatment for acquired cardiac structural abnormalities (ventricular septal perforation blocking after acute myocardial infarction; ventricular wall tumor blocking umbrella interventional decompression after myocardial infarction) 5.Interventional treatment for venous thrombosis (venous thrombosis ablation; vena cava filter implantation; venous stent implantation for venous stenosis) 6.Atrial fibrillation left ear blocking, prevention of left atrial thrombosis.
