A 28-year-old woman is referred for evaluation of persistent dyspnea related to mitral stenosis. The patient is 30 weeks pregnant, and her dyspnea persists despite treatment with metoprolol, furosemide, and digoxin. Her heart rate is 70/min. An echocardiogram shows severe mitral valve stenosis, with a mean gradient of 14 mm Hg and a mitral valve area of 1 cm2. Trivial mitral valve regurgitation is noted. The estimated right ventricular systolic pressure is 50 mm Hg. She has crackles in both lung bases and bilateral lower extremity edema.
