Diagnostic Considerations

Pregnant women with mild-to-moderate mitral stenosis can almost always be managed with judicious use of diuretics and beta blockade.

Pregnant women with severe mitral stenosis who are symptomatic before conception will not predictably tolerate the hemodynamic burden of pregnancy and should be considered for percutaneous balloon mitral valvotomy before conception provided the valve is anatomically suitable.

Patients with severe mitral stenosis who develop NYHA functional class III–IV symptoms during pregnancy should undergo percutaneous balloon valvotomy.

Other conditions to be considered in patients with suspected mitral stenosis include the following:

  • Left atrial myxoma

  • Ball valve thrombus

  • Endocarditis

  • Massive mitral annular calcification
