Severe left ventricular dynamic outflow tract gradient secondary to localized septal hypertrophy and concomitant acute ischaemic parietal dyssynergy.
Localized basal septal hypertrophy (LSH) is usually an incidental echocardiographic finding and, as opposed to asymmetric hypertrophic cardiomyopathy (AHC), is of no clinical significance. We report a case of a patient with LSH who developed a severe left ventricular outflow gradient during acute myocardial ischaemia, apical akinesis and compensatory hyperkinesis of basal parietal segments.
