New methods of making blocked coronary arteries patent again.

摘要: The use of percutaneous transluminal coronary angioplasty is limited by procedural complications and the serious drawback restenosis, but some new techniques have been developed in an attempt to lower complication rate for difficult lesions reduce restenosis. These include devices physically remove atheromatous plaque, such as Simpson Coronary AtheroCath extraction catheter, well ablate plaque situ, including Rotablator excimer laser catheter. Although each device may advantages certain types lesion, few data on their reported properly controlled randomised trials. available so far do not suggest that these will be safer than balloon or they However, using metallic stents support arteries after seems acute likely increase.
