Originally published23 Jan 2001https://doi.org/10.1161/01.CIR.103.3.e15Circulation. 2001;103:e15–e17We present 4D images of hypertrophied myocardium in patients with essential hypertension, hypertrophic cardiomyopathy with asymmetrical septal hypertrophy, and apical hypertrophic cardiomyopathy using helical computed tomography (CT) ( Figures 1 through 4).Previously, we reported on 4D CT-ventriculography, which can assess right and left ventricular morphology and motion.1 In 4D ventriculography, we used only information about the inner cavities of the heart, and we discarded information regarding the myocardium. However, it is important to estimate the extent and function of the hypertrophied myocardium. Therefore, we retrieved and dealt with informa-tion about the myocardium as demonstrated in a 4D manner (4D myocardiography).Methods of data acquisition were the same for 4D CT-ventriculography as was reported previously.1 Four-dimensional myocardiography can analyze the detailed characteristics of hypertrophic myocardium in both ventricles noninvasively. It provides an assessment of myo-cardial volume, shape, and size and the extent of myocardial hypertrophy in any cardiac phase and in any perspective.Animated versions of Figures 2 through 4 can be found at http://www.circulationaha.orgThe editor of Images in Cardiovascular Medicine is Hugh A. McAllister, Jr, MD, Chief, Department of Pathology, St Luke's Episcopal Hospital and Texas Heart Institute, and Clinical Professor of Pathology, University of Texas Medical School and Baylor College of Medicine.Circulation encourages readers to submit cardiovascular images to the Circulation Editorial Office, St Luke's Episcopal Hospital/Texas Heart Institute, 6720 Bertner Ave, MC1-267, Houston, TX 77030.(Circulation. 2001;103:e15-e17.)Download figureDownload PowerPoint Figure 1.

Images from a patient with essential hypertension at end-diastole (ED) and end-systole (ES). Left, 4D myocardiography (4D-MG); middle, 4D ventriculography (4D-VG); and right, watermarked display of 4D myocardiography and 4D ventriculography. The 4D ventriculography shows both right and left ventricular cavities and wall motion. The 4D myocardiography provides detailed myocardial images and whole dynamics of wall motion and systolic thickening of both ventricles. Myocardial hypertrophy is concentric and uniform. RV indicates right ventricle; LV, left ventricle; and IVS, intraventricular septum.

Views from a patient with hypertrophic cardiomyopathy with asymmetrical septal hypertrophy (*) at end-diastole (ED) and end-systole (ES). Left, 4D myocardiography (4D-MG); middle, 4D ventriculography (4D-VG); and right, watermarked display of 4D myocardiography and 4D ventriculography. The 4D myocardiography and watermarked images clearly demonstrate asymmetrical septal hypertrophy. The mid-interventricular septum (IVS) bulges into left ventricular cavity (LV). The 4D ventriculography demonstrates the bending ("banana"-shaped) left ventricle (**). Left ventricle is usually more involved in hypertrophic process than right ventricle (RV); however, hypertrophy in both ventricles was observed in this patient.

Left, 4D myocardiography (4D-MG); middle, 4D ventriculography (4D-VG); and right, watermarked display of 4D myocardiography and 4D ventriculography. The 4D myocardiography and the watermarked display clearly demonstrate the apical hypertrophy (*). The 4D myocardiography discloses severe hypertrophy confined to apex and interventricular septum (IVS) at the apex. LV indicates left ventricle; RV, right ventricle.
