Since the invention of percutaneous transluminal coronary angioplasty for angina pectoris by Grüentzig in 1977, less invasive percutaneous coronary intervention (PCI) has become an advantage over coronary artery bypass grafting (CABG). It quickly spread around the world (first paradigm shift). From the initial balloon dilatation to the proliferation of new devices, complex lesions (calcified, diffuse and chronic total occlusive lesions, etc.) were also targeted. The introduction of antithrombotic therapy, endovascular imaging and quantitative coronary angiography in core laboratories to objectively evaluate the effects of the devices have all contributed to the evolution of PCI during this period. More recently, the duration of dual antiplatelet therapy has been shortened and convenience has increased.
