Left atrial compression (LAC) is an uncommon condition that causes left ventricular inflow obstruction. The clinical and pathologic features are similar to those of mitral stenosis. Impaired left ventricular filling may cause hypotension, syncope, or shock. The increased left atrial pressure causes retrograde increase of the pressure throughout the pulmonary circulation with subsequent signs of congestion.
