1 Pulmonary root translocation in malposition of great arteries repair allows right ventricular outflow tract growth  José Pedro da Silva, MD, Luciana da Fonseca da Silva, MD, Lilian Maria Lopes, MD, Luiz Felipe Moreira, MD, Luiz Fernando Caneo, MD, Sonia Meiken Franchi, MD, Alessandro Cavalcanti Lianza, MD, José Francisco Baumgratz, MD, Jefferson Duarte Flavio Magalhaes, MD  The Journal of Thoracic and Cardiovascular Surgery  Volume 143, Issue 6, Pages (June 2012) DOI: /j.jtcvs Copyright © 2012 The American Association for Thoracic Surgery Terms and Conditions

2 Figure 1 A, The pulmonary root is dissected out and its origin is closed using a glutaraldehyde-treated autologous pericardial patch. B, After partial resection of the conal septum, a Dacron patch is used to create a tunnel from the left ventricle to the aorta. C, The pulmonary root is sutured to the right ventriculotomy with a running 6-0 polydioxanone suture, and the right ventricular outflow tract is completed using an in situ pericardial patch combined with a glutaraldehyde-treated autologous pericardial patch. D, The final appearance after the procedure.

4 Figure 3 Data from repeated postoperative echocardiograms performed in 20 patients with more than 1 year of follow-up after pulmonary root translocation without patch enlargement. The data show changes over time in pulmonary valve diameter (A) and in the pressure gradient across the pulmonary valve (B). Each line represents data from individual patients, and the bold line represents the average time trend for the longitudinal data model.

5 Figure 4 Data from preoperative and repeated postoperative echocardiograms performed in 10 patients with more than 1 year of follow-up after pulmonary root translocation with patch enlargement. The data show changes over time in pulmonary valve diameter (A) and pressure gradients across the pulmonary valve (B). Each curve represents data from individual patients, and the bold curve represents the average time trend for the longitudinal data model.

6 Figure 5 Echocardiographic images from a girl who underwent pulmonary root translocation surgery at 5 years of age: preoperative cross-sectional view of the aortic and pulmonary valves on the day of the surgery (A), and postoperative views of the translocated pulmonary valve after 3 years (B) and 8.5 years (C) of follow-up. AVD, Aortic valve diameter; PVD, pulmonary valve diameter; AO, aorta.
