Aj. Lakowsky et al., Use of intravenous esmolol in patient with severe heart failure and abnormal intraventricular gradient post aortic valve replacement, REV ESP CAR, 53(5), 2000, pp. 758-760
The presence of anomalous intraventricular flows of high velocity and dynam
ic ejective obstruction of the left ventricle post aortic valve replacement
, generally by severe aortic stenosis, is a relatively infrequent, but seve
re complication.
An early diagnosis is of crucial importance, since the usual treatments app
lied 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.
