What is the clinical significance of the opening snap in patients with chronic rheumatic heart disease and mitral incompetence?
The clinical significance of the opening snap in mitral valve disease has been historically debated, particularly regarding its relationship to valve rigidity and mitral regurgitation.

Leaves clinical role of opening snap unresolved in mitral incompetence; leaves open its diagnostic value in rheumatic disease.
The mitral valve opens with a loud snap in some patients suffering from chronic rheumatic heart disease. The features by which the sound may be recognized have been described clearly by Mar- golies and Wolferth (1932) and by The significance of the opening snap has been disputed. Mounsey (1953) did not hear the opening snap in cases where the valves had lost suppleness. McDonald et al. (1957) regarded the sound as an important clue to the ease with which mitral stenosis may be surgically relieved. On the other hand, Turner and Fraser (1956) found loud opening snaps in patients with rigid valves, and in patients with dominant mitral regurgitation.
