For certain congenital heart diseases that cannot be surgically corrected or are temporarily unsuitable for surgery, some interventional techniques can be used as palliative measures. These procedures aim to alleviate symptoms, provide temporary relief, or prepare the patient for future surgical opportunities.
Percutaneous Balloon Angioplasty and Stent/Valve Implantation
These procedures can be applied in the following conditions:
- Congenital coarctation of the aorta
- Isolated stenosis of the main pulmonary artery or its branches distal to the pulmonary valve
- Pulmonary artery branch stenosis or pulmonary valve insufficiency in patients with tetralogy of Fallot who cannot undergo complete surgical correction
- Pulmonary valve regurgitation following right ventricular outflow tract reconstruction
Artificial Atrial Septostomy
This procedure can be used in the following cases:
- Neonates or infants with severe cyanotic heart disease and an intact ventricular septum
- Severe congenital mitral stenosis or mitral atresia
- Total anomalous pulmonary venous drainage
Abnormal Vessel Occlusion with Coils
This technique is used for:
- Congenital pulmonary arteriovenous fistulas
- Abnormal vascular channels following palliative surgery for congenital heart diseases
