An important step to prevent the development of a \u201cnapkin ring\u201d was to implant a second larger stent before dilatation with ultra\u2010high pressure balloons (fracturing procedure). In 17 patients, previously implanted stents were dilated serially and ultimately fractured. The stents had been implanted in branch pulmonary arteries (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u20099), in the right ventricular outflow tract (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u20093), and in the aortic isthmus (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u20095). After dilation up to the fracturing diameter known from the benchside tests, a second larger stent was implanted and the initial stent was fractured with ultra\u2010high\u2010pressure dilatation. Fracturing of the stent was possible in all patients.
