Key result
Transillumination improves visualization of unicuspid aortic valve morphology over standard echocardiography.
Why the study?
Timely detection of unicuspid aortic valve is crucial but two-dimensional echocardiography has suboptimal diagnostic performance for distinguishing UAV from bicuspid aortic valve.
Does transillumination improve the visualization of morphological characteristics in unicuspid aortic valves compared to two-dimensional echocardiography?

Does transillumination improve the visualization of morphological characteristics in unicuspid aortic valves compared to two-dimensional echocardiography?
Transillumination improves the visualization of unicuspid aortic valve morphology, aiding in its distinction from bicuspid aortic valves.
May aid unicuspid aortic valve assessment in select cases; leaves open need for prospective validation versus standard imaging.
Unicuspid aortic valve (UAV) is a rare congenital malformation which portends an augmented risk of early valve degeneration. Timely detection of this cardiac valvular anomaly is crucial because a strict follow-up is warranted. Currently, the best morphological information is provided by two-dimensional echocardiography; however, its diagnostic performance has been found to be suboptimal by some anatomical features, making it tough to distinguish between UAV and bicuspid aortic valve. Transillumination is a photo-realism technique that employs the use of a virtual light source that simulates the interaction of light on 3-dimensional surfaces, improving the visualization of morphological characteristics. Our report highlights the incremental value of photo-realistic rendering and lighting source technology to better define the aortic valve morphology.

Malagoli et al. (2021) conducted a case report in Unicuspid aortic valve. Transillumination (photo-realistic rendering) vs. Two-dimensional echocardiography was evaluated on Visualization of morphological characteristics. Transillumination using photo-realistic rendering and lighting source technology improves the visualization and definition of unicuspid aortic valve morphology.
