Stenting, an attractive nmedical term, that involves deploying a coil or tube (metal or non-metal) inside the human biological system that supports and scaffolds vessel wall, tracts, cavities and prevents it from closing again. Conceptually it could be termed as the simplest innovation in an otherwise complex industrial world. Originally used in various biological tracts like ureter, bile duct, esophagus, and others. In fact, the concept is so simple it can be effectively used wherever there is a tissue level occlusion which interrupts a biological function.
No wonder It has become revolutionary modality especially in cardiovascular disease and it is the most common intervention done where stents are used to keep vital coronary arteries open. While 9 out of 10 stents in cardiology would be in adults within the coronary arteries there are some unique indications for stenting in infants and children in various congenital heart disease.
In congenital heart disease stents are used within chambers, outflow tracts, or septal orifices or even across valves to maintain or divert or maintain blood flow.
1. Coarctation of aorta
2. Right ventricular outflow tract (RVOT) conduits.
3. Maintenance of patency of the Arterial duct in duct-dependent circulation,
4. Maintaining patency of stenosed aortopulmonary collateral vessels or obstructed shunts.
5. Stenting a PFO / ASD is also possible to maintain patency of intracardiac communications in TGV and related entities
6. Recently Interatrial flow regulators are used in in HFpEF. (EuroIntervention 2019;15:403-410. DOI: 10.4244/EIJ-D-19-00342)
The list is incomplete and can be used anywhere when you feel the flow is obstructed and that needs to be opened up.
