Left ventricular outflow tract obstruction following an uncomplicated primary percutaneous coronary intervention: a recognized but rare cause of cardiogenic shock.
Dynamic left ventricular outflow tract obstruction is a rare but important complication of myocardial infarction. It occurs acutely and may mimic the presentation of papillary muscle rupture or acquired ventricular septal defect. Unlike these mechanical complications, it does not require circulatory support or cardiac surgical intervention. Recognition is critical because it typically responds to volume loading and beta blockade. We report a case who displayed many classical features of this condition.
