Supports feasibility of coil occlusion for pediatric perivalvular mitral leak hemolysis; hypothesis-generating case report requiring prospective validation.
A 6-year-old malnourished child had persisting hemolysis after attempted valve repair and two surgeries for mitral valve replacement due to partial dehiscence of the valve ring. A modified catheter delivery system was utilized to deploy a total of six Gianturco coils. The hemolysis resolved and the patient was doing well 17 months later. The technique may be helpful in other patients with perivalvular mitral leaks. Cathet. Cardiovasc. Intervent. 49:64-67, 2000.
