Real-time three-dimensional echocardiography provides unique views of the left atrioventricular valve, improving the understanding of valve morphology and function to facilitate surgical planning.
Real-time 3D echocardiography provides superior visualization of complex congenital left atrioventricular valve abnormalities compared to standard 2D imaging, which can facilitate surgical planning.
May enhance preoperative planning for complex left atrioventricular valve repair; leaves open need for prospective outcome validation.
Congenital abnormalities of the left atrioventricular (AV) valve are a significant diagnostic challenge. Traditionally, reliance has been placed on two-dimensional echocardiographic (2DE) imaging to guide recognition of the specific morphological features. Real-time 3DE can provide unique views of the left AV valve with the potential to improve understanding of valve morphology and function to facilitate surgical planning. This review illustrates the features of congenital abnormalities of the left AV valve assessed by 3DE. The similarities and differences in morphology between different lesions are described, both with respect to the valve itself and supporting chordal apparatus. The potential advantages as well as limitations of this technique in clinical practice are outlined.

Rice et al. (2015) conducted a review in Congenital abnormalities of the left atrioventricular valve. Real-time three-dimensional echocardiography (RT3DE) vs. Two-dimensional echocardiography (2DE) was evaluated. Real-time three-dimensional echocardiography provides unique views of the left atrioventricular valve, improving the understanding of valve morphology and function to facilitate surgical planning.
