Angioplasty (Balloon Dilatation)

If a serious constriction (stenosis) is found during a diagnostic cardiac catheterization, it can be opened up. After the diagnostic cardiac catheterization, we often look for the constricted coronary vessel in question again with a somewhat larger cardiac catheter. Monitored on X-rays, a thin wire is inserted through the stenosis into the vascular section behind it. The wire serves as a track for the balloon, so that the balloon glides along the wire right to the site of the constriction. There the balloon is pumped up with high pressure of at least 8 to 10 bar so that the stenosis is dilated. An angioplasty alone is a rather seldom procedure. Usually it is conducted together with or after a stent implantation. Yet under certain requirements, the dilatation alone may also be justified and conducted with a drug-coated balloon (DEB = drug-eluting stent).
