Bevezetés: A noncompaction cardiomyopathia a myocardium kompaktálódásának hiányában kialakuló kórkép, amely a bal kamra diszfunkciójával jár együtt. Célkitűzés: Jelen tanulmány célja a balkamra-diszfunkció összehasonlító vizsgálata volt kétdimenziós echokardiográfia és háromdimenziós speckle-tracking echokardiográfia során noncompaction cardiomyopathiában. Módszer: Jelen tanulmányban hét, noncompaction cardiomyopathiában szenvedő beteget (62,9±8,5 év, három férfi) és 10, korban és nemben egyeztetett kontrollesetet (60,7±7,7 év, két férfi) vizsgáltak kétdimenziós echokardiográfia és háromdimenziós speckle-tracking echokardiográfia során a bal kamra funkciójának vizsgálata céljából. Eredmények: Emelkedett bal kamrai végdiasztolés és végszisztolés térfogatértékek, valamint csökkent bal kamrai ejekciós frakció volt igazolható noncompaction cardiomyopathia fennállása esetén. Valamennyi háromdimenziós speckle-tracking echokardiográfia során számított strainparaméter csökkentnek bizonyult noncompaction cardiomyopathia esetén a kontrollokhoz képest. A háromdimenziós speckle-tracking echokardiográfia során mért rotációs paraméterek a bal kamra apicalis és basalis szegmentumainak egyirányú mozgását („rigid body rotation”) igazolták noncompaction cardiomyopathiában. Következtetések: A bal kamra funkciója és szegmentumainak kontraktilitása lényegesen beszűkült noncompaction cardiomyopathiában. A bal kamrai csavarodás (twist) noncompaction cardiomyopathia fennállása esetén hiányzik. Orv. Hetil., 2013, 154, 1352–1359.
