Pulmonary artery angioplasty (main pulmonary artery rotation flap technique) in tetralogy of Fallot patients with acute-angle branch pulmonary artery stenosis

Despite excellent outcomes of tetralogy of Fallot (TOF) repair, reinterventions for recurrent or residual stenosis of branch pulmonary arteries are still required in many patients. The development of these lesions may be related to two inherent characteristic morphologies of TOF: Pulmonary ductal coarctation and acute angulation of branch pulmonary artery, especially the left pulmonary artery. I developed a main pulmonary artery (MPA) rotation flap angioplasty technique to deal with acute-angle branch pulmonary artery stenosis without using any patch.
