Objective:
The feasibility in diagnosing congenital heart diseases using 3 dimensional (3D) echocardiography datasets at a remote setting has yet not been investigated. We aimed to evaluate the accuracy and efficacy of 3D findings against the conventional two-dimensional (2D) echocardiography and intra operative findings.
Methods and Results:
Thirty patients age ranged from 11 months to 18 years, underwent 2D and 3D echocardiography assessment at centre A (Kingdom of Saudi Arabia). 2D images were analysed while 3D full volume datasets were stored and exported for detailed analysis by independent experts in centre B (United Kingdom). All data from baseline characteristics, diagnostic findings on 2D and 3D echocardiography, and intra operative findings were evaluated. The 3D echocardiographic findings were measured against the 2D findings to determine the feasibility and accuracy of using 3D datasets for remote analysis. Our results show that independant and remote analysis of 3D echocardiography provide similar diagnostic information to that of 2D. 3D echocardiography is especially superior in anatomic delineation of complex cardiac abnormalities, providing good spatial orientation and the dynamic morphology of valves. 3D echocardiography also supplements 2D in assessment of functional haemodynamics, through its ability to measure the effective orifice area, vena contracta and ventricular volumes.
Conclusions:
Remote analysis of congenital heart diseases by 3D echocardiography is highly feasible and accurate, complementing 2D echocardiography examinations in the diagnosis and management of complex cardiac defects. It aids in decision making and discussion between professionals at diffrent geographic locations in the managemet of complex congenital heart defects.
