In these patients, several underlying causes of hypotension may co-exist, including vasoplegia, hypovolemia, drug-mediated venodilation, or myocardial dysfunction. Nowadays, echocardiography has been positioned as an essential tool in any ICU set to assess fluid status, ventricular ejection fraction, or any other myocardial complications. The high sympathetic tone in severely ill patients, in addition to high doses of adrenergic drugs often needed, may provoke a hypercontractile cardiac state. In the basis of our experience, we present a case of a patient with refractory septic shock and severe hemodynamic collapse, refractory to vasopressors with concomitant respiratory deterioration due to dynamic left ventricular outflow tract obstruction (LVOTO). Transesophageal echocardiography (TOE) was used to assess hemodynamic status and to guide treatment. A critical response to intravenous \u03b2-blockers was seen, with a dramatic decrease in vasopressor dosage and respiratory support.<\/jats:p>","DOI":"10.1177\/23247096211056491","type":"journal-article","created":{"date-parts":[[2021,12,9]],"date-time":"2021-12-09T02:06:11Z","timestamp":1639015571000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Beta
