We report a case of a 73-year-old female patient, who was admitted to the coronary care unit due to chest pain, malaise and near syncope. During physical examination, the patient was hypotensive and there were signs of left-sided heart failure and a loud systolic murmur. Echocardiogram showed apical ballooning with dynamic left ventricular outflow tract obstruction, based on systolic anterior motion of the mitral valve with important mitral valve regurgitation. In the acute setting, the cardiogenic shock was treated cautiously with fluid resuscitation and intravenous metoprolol, resulting in direct stabilisation of her haemodynamic condition. As a codiagnosis, there was a significant stenosis of left anterior descending artery, which was treated successfully by percutaneous coronary intervention with drug eluting stents. During follow-up, left ventricular function normalised, and the left ventricular outflow tract obstruction, systolic anterior motion of mitral valve and related mitral regurgitation all resolved.

We describe a case of severe left ventricular outflow tract obstruction (LVOTO) with severe mitral incompetence due to systolic anterior motion of the anterior mitral leaflet (SAM) that was recognised thanks to the immediate availability of transoesophageal echocardiography during the resuscitation of anaphylactic shock. The patient rapidly responded to cessation of the epinephrine (adrenaline) infusion and intravascular volume expansion with intravenous crystalloid. The absence of risk factors for developing SAM/LVOTO serve as a warning to clinicians to consider this diagnosis in all cases of epinephrine non-responsive anaphylactic shock.
