1 Ring-Reinforced Sano Conduit at Norwood Stage I Reduces Proximal Conduit Obstruction 
Christopher W. Baird, MD, Patrick O. Myers, MD, Michele Borisuk, MSN, CPNP, Frank A. Pigula, MD, Sitaram M. Emani, MD  The Annals of Thoracic Surgery  Volume 99, Issue 1, Pages (January 2015) DOI: /j.athoracsur Copyright © 2015 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 A series of magnetic resonance images from a patient having undergone a stage I procedure with a right ventricle-to-pulmonary artery conduit just before a bidirectional Glenn procedure. It shows very localized right ventricular hypokinesis/dyskinesis around the “dunked” right ventricle-to-pulmonary artery conduit insertion site, with no evidence of late gadolinium enhancement suggesting preserved ventricular function.

3 Fig 2 Kaplan-Meier estimates of freedom from interstage right ventricle-to-pulmonary artery (RV-PA) conduit proximal insertion site (A) reintervention and (B) complications for dunked conduit (blue line) and traditional conduit (green line). Complications were defined as reintervention, reoperation, moderate to severe obstruction without reintervention or reoperation at follow-up, or bidirectional Glenn procedure or pseudoaneurysm development.

5 Fig 4 Postmortem studies examining a ringed Gore-Tex (W.L. Gore and Associates, Elkton, MD) conduit dunked into the right ventricular infundibulum. (A) Magnetic resonance imaging details the course of the modified Sano conduit. (B) Gross pathologic specimen shows the ring-reinforced Gore-Tex Sano conduit inserted into the infundibulum of the right ventricle, without evidence of proximal conduit obstruction.
