  • Title: A surgical approach for S,L,L single ventricle incorporating total right atrium--pulmonary artery diversion.
    Author: Moreno-Cabral RJ, Miller DC, Oyer PE, Stinson EB, Reitz BA, Shumway NE.
    Journal: J Thorac Cardiovasc Surg; 1980 Feb; 79(2):202-10. PubMed ID: 7188708.
    Abstract:
    Patients with single ventricle and unfavorable anatomy for partitioning procedures have been considered inoperable. Such was the case in two patients with single ventricle and subaortic inverted (hypoplastic) infundibulum associated with subaortic obstruction and levo-transposition of the great vessels (S,L,L). Both had undergone pulmonary artery banding in infancy and presented 11 and 14 years later, cyanotic and severely incapacitated. Both patients were treated surgically by resection of the subaortic obstruction, patch closure of the right artrioventricular valve, closure of the proximal pulmonary artery, and diversion of systemic venous flow through a xenograft valved conduit from the right atrium to the distal pulmonary artery. Early postoperative complications included atrial dysrhythmias and right-sided congestion. The first patient, who had massive cardiomegaly and complete heart block preoperatively, developed congestive failure 20 months postoperatively. The second patient has an excellent functional result and is leading a normal life 1 years after operation. This procedure may be of value for patients with single ventricle in whom corrective ventricular septation is considered too risky or technically unfeasible.
