Figure 3 Right heart catheterization and angiography with percutaneous right pulmonary artery balloon angioplasty(A) Right ventricular angiography reveals stenosis of the right pulmonary artery. (B) A 4.5×15 mm balloon catheter was used to dilate the right pulmonary artery. (C) A 6×40 mm balloon catheter was used to dilate the right pulmonary artery. (D) An 8×20 mm balloon catheter was used to dilate the right pulmonary artery. (E) Post-balloon pulmonary angiography demonstrated enhanced visualization of the right pulmonary artery, with pronounced reduction in stenosis and restoration of unobstructed blood flow through the previously narrowed segment after balloon removal.
