Novel arterioplasty of severe left pulmonary artery stenosis using native main pulmonary artery

There are multiple approaches described for the repair of stenosed branch pulmonary arteries. Regardless of the technique used, restenosis is common. We describe a case of severe left pulmonary artery stenosis repaired with a novel technique using the native main pulmonary artery which was transected and turned down to create a direct anastomosis with the left pulmonary artery. This tension-free tissue to tissue anastomosis resulted in hemodynamically gratifying results with the potential for growth.

Automated summary

Repairing stenosed branch pulmonary arteries can lead to restenosis, regardless of the technique used. A novel technique involving a tension-free tissue to tissue anastomosis using the native main pulmonary artery showed promising hemodynamic results and potential for growth.
