Systolic Anterior Movement

In the perioperative setting, norepinephrine is used to increase blood pressure, an effect mediated mostly via arterial and venous vasoconstriction. Thus, norepinephrine is, allegedly, less likely to cause or worsen left ventricular outflow tract obstruction (LVOTO) than other inotropes. We report a case of norepinephrine-associated dynamic LVOTO and systolic anterior movement in a predisposed patient. This report highlights that unrecognised dynamic LVOTO may worsen shock parameters in patients treated with norepinephrine who have underlying myocardial hypertrophy.

Abstract Isolated sub-pulmonary membrane is a rare condition, the origin of which has been debatable. Transcatheter treatment of pulmonary valve atresia with intact interventricular septum by radiofrequency perforation and balloon dilatation to restore biventricular circulation is gaining more popularity, with improving results over time. We report in our experience of 79 cases in 10 years the development of a sub-pulmonary membrane in 4 cases: causing significant obstruction requiring surgical excision in one case that revealed a fibrous membrane on pathology; causing mild right ventricular outflow tract obstruction in another and not yet causing obstruction in 2. On cardiac MRI, the right ventricular outflow tract and the right ventricular outflow tract/pulmonary atresia angle showed no morphological abnormalities.
