A 50-year-old female patient (BSA= 1.6 m2) with severe rheumatic mitral valve stenosis (area at planimetry= 1.4 cm2; mean gradient= 7 mmHg; PHT area= 1.4 cm2), chronic atrial fibrillation and severe LV systolic dysfunction (Ejection fraction= 37 %) was admitted for mitral valve replacement surgery.
LV end-diastolic volume= 53 ml/m2 with diffuse hypokinesis; normal wall thickness; increased estimated left atrial pressure (pulmonary regurgitation end-diastolic gradient= 12 mmHg); normal estimated pulmonary systolic pressure (32 mmHg). Normal right ventricular systolic function; mild tricuspid regurgitation.
The left atrium was severely dilated (end-systolic volume= 86 ml/m2) with evidence of 2 thrombi inside the left atrial appendage and on the lateral atrial wall (Figure 1).
