New Treatment Strategy Of PCI-clinical Research Analysis Of Drug Coated Balloon And Bioresorbable Vascular Scaffold

Objective:to analyze and summarize the large-scale clinical randomized controlled trials of drug-coated balloons and bioabsorbable stents in coronary interventional therapy Methods: Obtain a large amount of literature in the database,and a large number of experimental studies have been carried out by reading various domestic and foreign literatures and summarizing drug-coated balloons and bioresorbable stents.Patients with drug-coated balloons were collected and followed up in the cardiac catheterization room,and their indications and postoperative adverse events were mastered in combination with clinical practice.Conclusion: Percutaneous coronary intervention is currently the mainstream of symptomatic coronary heart disease in China and abroad,implanted stents and other percutaneous coronary interventions are also considered to be the most convenient and effective treatment.Ten years ago,the emergence of drug-eluting stents promoted the development of coronary intervention,but in-stent restenosis and complex lesions(small vessel disease,bifurcation lesions,diffuse lesions)have not been completely resolved.Recently,drug-coated balloons and bioresorbable scaffold have been shown to provide an attractive new tool for the ?leave nothing behind? strategy.This article briefly introduces the development of percutaneous coronary intervention summarizes a series of randomized clinical controlled trials of drug-coated balloons and bioabsorbable stents.At present,drug-coated balloons and bioresorbable stents have good application prospects,but they also have their own defects.Drug balloons and bioresorbable stents still have a long way to go in place of drug-eluting stents in routine clinical applications.
