1 Percutaneous Pulmonary Valve Replacement: 3-Month Evaluation of Self-Expanding Valved Stents 
Tim Attmann, MD, René Quaden, MD, Thomas Jahnke, MD, PhD, Stefan Muller-Hulsbeck, MD, PhD, Andreas Boening, MD, PhD, Jochen Cremer, MD, PhD, Georg Lutter, MD, PhD  The Annals of Thoracic Surgery  Volume 82, Issue 2, Pages (August 2006) DOI: /j.athoracsur Copyright © 2006 The Society of Thoracic Surgeons Terms and Conditions

3 Fig 2 Representative angiography at the 3-month follow-up demonstrating a competent valved stent in the pulmonary position. Chronological sequence from a to d. (a) Early phase; (b) complete contrast in the pulmonary arteries; (c) still complete contrast in the pulmonary arteries without regurgitation; (d) late phase.

4 Fig 3 Representative transthoracic echocardiographic image after 3 months of implantation. Note marked difference in (1) systolic valved stent diameter and (2) diastolic valved stent diameter.

5 Fig 4 Representative macroscopic image of an ovine heart at postmortem. Right ventricle and its outflow tract are opened. Valved stent in pulmonary position with thin and transparent leaflets. The visible central defect of the valve disappeared during water rinse testing.

6 Fig 5 Representative roentgenogram images of a valved stent after 3 months of pulmonary implantation: (a) side view and (b) view from above. Note only minimal calcification of the wall of the bovine jugular vein and absent calcification of the leaflets.
