A new instrument for surgical exposure of subaortic and subpulmonic stenosis.
An instrument for providing adequate visualization of the subvalvular area during repair of intracardiac defects is described. Essentially a type of modified nasal speculum, the instrument has proved helpful in performing resections in both subaortic and subpulmonic stenoses by exposing a wider surgical field.
