Cardiomyopathy associated with left ventricular outflow tract obstruction (LVOT) is a rare cause of persistent perioperative hypotension. One of the causes of this association is the systolic anterior motion (SAM) of the mitral valve. We report a case of a 67-year-old woman who, after undergoing liver segmentectomy because of metastasis, presents post-operative hypotension that is difficult to manage. Upon evaluation with a transthoracic echocardiogram, the diagnostic suspicion of syndrome associated with LVOT obstruction secondary to SAM was raised. As initial therapy, a volume expander, in association with propanolol and phenylephrine were administred, achieving partial hemodynamic response. Later, she evolved with signs of heart failure and was transferred to the intensive care unit for management. In this unit, non-invasive ventilatory support, diuretic and vasopressor therapy were required, achieving favorable results on the second post-operative day. Echocardiography was essential to make the differential diagnosis against a persistent post-operative hypotension.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
