Valve Template Design and Applications
Keywords:
Valve conduit, pericardium, aortic root, valve templateAbstract
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.
