Apical inflow is associated with increased energy loss during left ventricular diastole in patients with a repaired atrioventricular septal defect: a 4D flow MRI study
نویسندگان
چکیده
Background Patients after atrioventricular septal defect (AVSD) repair have aberrant atrioventricular valve morphology resulting in a disorganized left ventricular (LV) inflow [1] with an increased amount of inflow reaching the apical level of the LV and retaining there during the subsequent systole [1]. This may elevate energy loss in LV flow due to friction. We aimed to evaluate the association between the percentages (retained) apical inflow with viscous energy loss during diastole in AVSD-repaired patients compared to healthy controls using 4D flow MRI.

Elevated energy loss in diastolic left ventricular inflow corresponds to an increase in kinetic energy in patients with a repaired atrioventricular septal defect: Quantification from 4D Flow MRI
Background Patients after atrioventricular septal defect (AVSD) repair may present abnormalities in valve morphology and subsequently develop altered left ventricular (LV) inflow patterns [1]. This may lead to energy loss and affect the kinetic energy in the LV. We aimed to quantify diastolic viscous energy loss and kinetic energy in the LV and to evaluate their association in AVSDrepaired pati...

Background Vortex formation in the left ventricle (LV) is suggested to contribute to efficient blood pumping and minimization of energy loss. Patients after atrioventricular septal defect (AVSD) repair may present abnormalities in valve morphology and subsequently develop altered LV inflow patterns [1], in which normal vortex formation may be disturbed. This may lead to energy loss. We aimed to...

PURPOSE To evaluate viscous energy loss and the association with three-dimensional (3D) vortex ring formation in left ventricular (LV) blood flow during diastolic filling. THEORY AND METHODS Thirty healthy volunteers were compared with 32 patients with corrected atrioventricular septal defect as unnatural mitral valve morphology and inflow are common in these patients. 4DFlow MRI was acquired...

Background The normal pattern of left ventricular (LV) inflow and ejection of affects the efficiency of cardiac pumping performance. Altered inflow direction due to a corrected atrioventricular septal defect (AVSD) may disturb this pattern leading to decreased efficiency. We aimed to quantitatively describe the LV blood flow pattern using 4-dimensional velocity-encoded cardiac magnetic resonanc...
