A 56-year-old female patient (BSA= 1.6 m2) was admitted for a previous diagnosis of “significant”rheumatic mitral valve stenosis. Blood pressure was normal and there was permanent atrial fibrillation. Heart rate= 74 bpm. The symptoms were limited to mild shortness of breath on exertion (NYHA II).
The transthoracic examination showed mild fibrotic thickening of the aortic valve; moderate left atrial dilatation (49 ml/m2); normal LV end-diastolic volume (41 ml/m2) and ejection fraction (61 %); normal mean estimated left atrial pressure (pulmonary regurgitation end-diastolic gradient= 6 mmHg) and pulmonary systolic pressure (21 mmHg); normal right ventricular size and systolic function and mild tricuspid regurgitation.
The mitral valve showed mild fibrotic thickening of the apical portion of the leaflets (Figures 1 and 2) and nodular calcifications of the sub-valvular apparatus; commissure fusion; akinesis of the posterior leaflet and moderate diastolic doming of the anterior leaflet.
The mitral valve planimetry in the short axis showed an area= 1.9 cm2.
The continuous wave Doppler exam showed a mean gradient= 2.2 mmHg (Figure 5) and a calculated area with PHT= 1.68 cm2 (Figures 4-6).
