Intraatrial mitral valve insertion with native valve preservation in children

Two patients underwent intraatrial mitral valve insertion for an unsuccessf ul valvotomy for severe mitral stenosis and left-sided atrioventricular val ve insufficiency associated with corrected transposition utilizing a porcin e valve from a valved conduit with preservation of the native valve. The va lves were inserted using continuous suture distally at the mitral annulus a nd proximally at the pulled atrial wall distal to the pulmonary veins. Both patients had uneventful hospital course and are doing well at up to 6 mont hs postoperatively. This approach provides a viable option for congenital m itral stenosis or insufficiency in children.
