In 1925 operations on the valves of the heart were unknown. Henry Souttar operated successfully on a young woman with mitral stenosis. He made an opening in the appendage of the left atrium and inserted a finger into this chamber in order to palpate and explore the damaged mitral valve. The patient survived for several yearsbut Souttar’s physician colleagues at that time decided the procedure was not justified and he could not continue.In 1948 four surgeons complete successful operations for mitral stenosis resulting from rheumatic fever.Horace Smithy (1914-1948) of Charlotte, revived an operation due to Dr Dwight Harken of the Peter Bent Brigham Hospital using a punch to remove a portion of the mitral valve.Charles Bailey at the Hahnemann Hospital,Philadelphia,Dwight Harken in Boston and Russell Brock at Guy's Hospital all adopted Souttar’s method..All these men started work independently of each other within a few months.This time Souttar’s technique was widely adopted although there were modifications.And in 1947 Thomas Holmes Sellors of the Middlesex Hospital operated on a Fallot’s Tetralogy patient with pulmonary stenosis and successfully divided the stenosed pulmonary valve.In 1949 Russell Brock probably unaware of Sellor’s work used a specially designed dilator in three cases of pulmonary stenosis.Later in 1948 he designed a punch to resect the infundibular muscle stenosis which is often associated with Fallot’s Tetralogy.
