Abstract
A transcatheter double-blade valvotome for cutting a stenotic pulmonary valve has been devised. The valvotome consists of a retractable rhomboid structure at its tip, with a blade on each side of its proximal half. By tugging the extended blades from the pulmonary artery to the right ventricle it is possible to tear the stenotic valve. After animal experiments proved the feasibility and safety of this method, it was used in three children with pulmonary stenosis. The results were encouraging.Entities:
