198 Possible Causes for Opening Snap

  • Mitral Valve Stenosis

    Opening Snap Opening of the stenotic mitral valve generates an audible "Opening Snap" immediately after S2, likely due to tensing of the thickened chordae tendineae.[] […] rumbling murmur with presystolic accentuation will be heard after the opening snap. [2] [10] The murmur is best heard at the apical region and is not radiated.[] The intensity of the Opening Snap is thought to correlate with the degree of mitral stenosis.[]

  • Streptococcus Pyogenes

    Physical exam reveals a diastolic murmur with an opening snap.[]

  • Pericardial Friction Rub

  • Congenital Mitral Stenosis

    snap” or diastolic rumble/murmur Mitral Stenosis Treatment Treatments for mitral stenosis include: Medications: Might include diuretics to limit shortness of breath; digitalis[] Opening Snap Opening of the stenotic mitral valve generates an audible "Opening Snap" immediately after S2, likely due to tensing of the thickened chordae tendineae.[] snap of the mitral valve after S 2 ; shorter interval between opening snap and S 2 indicative of more severe disease ; , because left atrial pressure is greater than left[]

  • Constrictive Pericarditis

    Opening snap of mitral valve is to be distinguished from pericardial knock.( Opening snap high pitched and occur later than pericardial knock in diastole , best heard in expiration[] The auscultatory impression tends to be that of a widely split S2 or a mitral opening snap.[] In constrictive pericarditis an earlier filling sound occurs, usually 0.06–0.12 s after S2, and somewhat high pitched and “snapping” in character.[]

  • Heart Murmur

    It may be associated with an opening snap. Increasing severity will shorten the time between S2(A2) and the opening snap. (i.e.[] The opening snap and murmur of mitral stenosis also respond to dynamic auscultation.[] In severe MS the opening snap will occur earlier after A2) Tricuspid valve stenosis presents as a diastolic decrescendo murmur at the left lower sternal border, and signs[]

  • Cor Triatriatum

    Features suggestive of the correct diagnosis would include the absence of an opening snap, the absence of a typical murmur of mitral stenosis, regular rhythm, and lesser evidence[] The absence of an opening snap or a loud S1 marks the difference between CTS and mitral stenosis.[]

  • Double-Orifice Mitral Valve

    Unlike acquired mitral stenosis, an opening snap is not commonly heard. A low-pitched mid-diastolic murmur of varying intensity is audible at the mitral area.[]

  • Atrial Myxoma

    Tumour sound in the early diastole could be misinterpreted like opening snap of mitral valvular stenosis, especially when the diastolic rumble is present.[] This is in contrast to the opening snap of rheumatic mitral valve stenosis which is high pitched. A tumor plop may be followed by a low pitched diastolic murmur.[] There were added sounds in diastole which were considered to be an opening snap or a probable third heart sound.[]

  • Rheumatic Valvulitis

    This can be distinguished from rheumatic mitral valve stenosis by the absence of an opening snap.[]
