1 Prosthetic Pulmonary Valve Stenosis: A Different Way to Solve the Problem 
Thomas Schroeter, MD, Philipp Lurz, MD, PhD, Philipp Kiefer, MD, Mahmoud Wehbe, MD, Ingo Dähnert, MD, PhD  The Annals of Thoracic Surgery  Volume 100, Issue 3, Pages (September 2015) DOI: /j.athoracsur Copyright © 2015 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 Angiography revealing the malrotation of the 2011 implanted biological pulmonary prosthesis (Medtronic Mosaic, 27 mm) with functional stenosis. For better illustration, the prosthesis framework is traced. 1 = pulmonary valve prosthesis, 2 = pulmonary artery, 3 = aortic valve prosthesis.

3 Fig 2 Result after implantation of the first stent (AndraStent XXL), which rotates the prosthesis toward the pulmonary artery. 1 = right ventricular outflow tract; 2 = sheet; 3 = aortic valve prosthesis.

4 Fig 3 Situs after implantation of three stents in prosthesis and pulmonary artery. The old prosthesis was effectively rotated and the malposition was corrected. The Melody valve is in position, but not yet opened. 1 = right ventricular outflow tract; 2 = Melody valve delivery system; 3 = aortic valve prosthesis.

5 Fig 4 Completion angiography. It revealed good prosthetic function with out paravalvular leak. No relevant gradient across the valve could be measured. 1 = right ventricular outflow tract; 2 = pigtail catheter; 3 = aortic valve prosthesis.
