Echocardiographic assessment of right ventricular volumes: a comparison of different techniques in children after surgical repair of tetralogy of Fallot

Abstract

Current echocardiographic techniques to assess RV volumes are highly feasible and reproducible in paediatric post-operative TOF patients. When compared with MRI measurements, 3DR was the most accurate technique but requires extra equipment that is not readily available.

Influence of RV Restrictive Physiology on LV Diastolic Function in Children after Tetralogy of Fallot Repair

“…Because of the retrospective nature of this study, we could not quantify RV volumes either by three-dimensional echocardiography or by 2D-based three-dimensional reconstruction. 19,20 As a surrogate, we used multiple 2D RV measurements obtained from different echocardiographic windows. We found that all the different RV measurements we performed (TV annulus, RV diameters 1 and 2, RV length, and RVend-diastolic area) were consistently larger in the patients with EDFF.…”

Current and future role of echocardiography in arrhythmogenic right ventricular dysplasia/cardiomyopathy

“…5) [37,38]. The reconstruction technique uses a magnetic field generator and a magnetic field sensor attached to the transducer to accurately localize 2D obtained RV anatomic landmarks within the magnetic field [37].…”

“…This 3D-based technique shows high correlation with MRI derived volumetric measurements in patients with pulmonary hypertension and congenital heart diseases. Inter-method correlation A B was 0.87-1.00 (RVEDV), 0.88-1.00 (RVESV), and 0.75-0.88 (RVEF) [37,38]. We currently lack studies with 3D-based RV reconstruction in ARVD/C patients.…”

Congenital heart disease in children

“…Recently, RV volume estimation has been achieved using »knowledge-based reconstruction« which utilizes a series of 2D images obtained from different sonographic projections and a tracked ultrasound probe. Initial results have shown good agreement with volumes obtained by MRI [67][69]. 10.6 · Role of RT3DE in the assessment of cardiac function in children .…”
