Dynamic subaortic stenosis with the use of vasoactive drugs in critical care: case report

Although the use of vasoactive drugs is widespread in the critical care setting, its use is associated sometimes with an undesirable hemodynamic outcome. The dynamic subaortic stenosis is a phenomenon described in the echocardiogram stress testing in which patients are submitted to the use of dobutamine. Similarly it could happen in the critical setting where high doses of vasoactives drugs are frequently prescribed, but to our knowledge this has never been described previously.
