Acute LV Dysfunction in the Critically Ill

• Approximately one-third of critically ill hospitalized patients develop acute LV dysfunction, most often due to a stress-induced cardiomyopathy.
• In these patients, up to 25% develop an acute dynamic LV outflow tract obstruction.
• Consider acute LV outflow tract obstruction in hypotensive patients with a new systolic ejection murmur in the left parasternal area.
• Aggressive IVFs is central to the management of these patients with LV outflow tract obstruction.
