Popis: | 2 per 1000 children in the US are born with functionally single ventricle (SV) heart defects. To restore the separate systemic and pulmonary circulations, a Total Cavopulmonary Connection (TCPC) is carried out through a series of surgical steps, which result in the direct connection of the superior vena cava (SVC) and inferior vena cava (IVC) to the pulmonary arteries without an intervening pulmonary ventricle. One way to complete the TCPC is by placing a synthetic patch in the right atrium, forming an intracardiac lateral tunnel (LT) as the final step. As patients grow, some LT pathways become stenosed. The stenosis can impose extra resistance to flow in addition to the TCPC in the SV circulation. One method of treating LT stenosis is by placement of an intravascular stent. |
