Catheter intervention is constantly evolving and has developed with increasing patient needs because it is less invasive than cardiovascular surgery. Catheter intervention can be used for various fields such as coronary artery disease (CAD), peripheral arterial disease (PAD), and structural heart disease (SHD) through the development of a variety of devices and techniques for each specific disease. Thus, catheter intervention has become the first choice in many fields because of its proven efficacy and safety. Although every patient may not be suitable, catheter-based treatment should be chosen for the best strategy based on the medical condition of the individual patient and their long-term prognosis.
