Background and Objective: To evaluate the results of autologous pericardial valve-conduit reconstruction, made with the help of metallic valve-conduit templates of various sizes specifically created for Thai patients. Methods: Metallic valve-conduit templates were made based on the diameters of the aortic root at the levels of the aortic annulus, the sinus of Valsalva and the sino-tubular junction derived from cine-angiography measurements in 20 Thai subjects. The average diameters at the3 levels were to the ratios of 1 to 1.50 to 1.13, respectively. These ratios were used in constructing valve-conduit templates of various sizes. Results: From 2001 to 2010, ten children underwent autologous pericardial valve-conduit reconstruction and one adult patient underwent pericardial valve replacement, using the metallic valve-conduit templates in the reconstruction. Of the seven children and one adult who survived the immediate postoperative period, the functions of the valves and conduits as measured by echocardiography were satisfactory. Only mild valvular regurgitation was seen postoperatively, although the regurgitation worsened with longer follow-up. Conclusion: Autologous pericardial valve-conduit reconstruction using metallic templates is a suitable alternative to other types of repairs. [ABSTRACT FROM AUTHOR]
