May warrant consideration of SAM with LVOTO in unexplained perioperative hypotension; case report leaves open need for prospective validation.
Case Report (n=3)
Systolic anterior motion of the mitral valve should be considered as a potential cause of severe perioperative hypotension in noncardiac surgery, requiring specific management with volume, vasopressors, and beta-blockers.
Margreiter et al. (2005) conducted a case report in Severe perioperative hypotension (n=3). Systolic anterior motion of the mitral valve was evaluated on Acute perioperative cardiovascular collapse. Systolic anterior motion of the mitral valve with left ventricular outflow obstruction is an unrecognized cause of acute perioperative cardiovascular collapse requiring volume infusion and vasopressors.
