  • Title: Partition of Common Atrioventricular Valve in a Patient With Dextrocardia and Univentricular Circulation.

    Journal: Semin Thorac Cardiovasc Surg; 2019; 31(1):113-115. PubMed ID: 30273646.
    Abstract:
    Long-term outcomes in children with atrioventricular septal defect (AVSD) and univentricular palliation are of concern, with <60% survival at 25 years.1 Common atrioventricular valves (AVV) often become insufficient in patients with univentricular physiology, leading to heart failure.1,2 We have recently observed that outcomes of children with AVSD who reach Fontan circulation are not as bad as previously thought, provided that the AVV remains competent.1 Common AVV surgery is associated with substantial mortality and reoperation rates.3 Although successful AVV repair is associated with better survival and freedom from reoperation, good quality repair is difficult to achieve in univentricular circulation,3 especially in patients with dextrocardia.4 Herein, we report a patient with unbalanced AVSD and dextrocardia who underwent AVV repair using the "polytetrafluoroethylene (Gore-Tex, W.L. Gore & Associates, Flagstaff, AZ) bridge" technique5 with excellent early outcome.
