[Technological improvements in interventional cardiology].
In the last few years, the evolution of coronary interventionism has been very important. The primary success rates in the early 1990s were 86-88% with a re-stenosis rate of 30%-40%. Current primary success rates have risen to over 95% with a re-stenosis rate of under 10% even for many types of lesions classically considered complex. Currently the main limitations in interventional cardiology remain coronary segments that cannot be accessed due to chronic total occlusion, or severe proximal tortuosity or calcification. Rapid improvements have led to broader clinical indications for percutaneous revascularization procedures. We describe the latest improvements in techniques.
