[Use of intravenous esmolol in patient with severe heart failure and abnormal intraventricular gradient after aortic valve replacement].
The presence of anomalous intraventricular flows of high velocity and dynamic ejective obstruction of the left ventricle post aortic valve replacement, generally by severe aortic stenosis, is a relatively infrequent, but severe complication. An early diagnosis is of crucial importance, since the usual treatments applied to postoperative heart failure are often inefficacious or even harmful. Even in cases of severe pump failure, when the clinical case is diagnosed adequately, endovenous short-action beta-blockers are useful.
