Abstract
INTRODUCTION: Noncompaction cardiomyopathy develops due to the absence of myocardial compaction, and is associated with left ventricular dysfunction. AIM: The aim of the study was to evaluate comparatively left ventricular dysfunction in patients with noncompaction cardiomyopathy using two-dimensional echocardiography and three-dimensional speckle-tracking echocardiography. METHOD: The present study comprised of 7 patients with noncompaction cardiomyopathy (62.9±8.5 years, 3 males) and 10 age- and gender-matched healthy controls (60.7±7.7 years, 2 males). All patients were examined by two-dimensional echocardiography and three-dimensional speckle-tracking echocardiography for the evaluation of left ventricular function. RESULTS: Increased left ventricular end-diastolic and end-systolic volumes and reduced left ventricular ejection fraction were detected in patients with noncompaction cardiomyopathy as compared to those measured in controls. All three-dimensional speckle-tracking echocardiography-derived strain parameters of patients with noncompaction cardiomyopathy were found to be reduced as compared to the values of controls. Three-dimensional speckle-tracking echocardiography-derived rotational parameters showed movements of the apical and basal segments in the same direction suggesting 'rigid body rotation' in all noncompaction cardiomyopathy cases. CONCLUSIONS: Left ventricular function and contractility are severely reduced in patients with noncompaction cardiomyopathy. Absence of left ventricular twist could be demonstrated in a series of noncompaction cardiomyopathy patients.
