In patients with mitral valve prolapse (MVP) eligible for surgery, three-dimensional echocardiographic (3DE) imaging is routinely used for preoperative assessment. Despite the worldwide use of transesophageal echocardiography in this context, transthoracic echocardiographic (TTE) imaging allows accurate noninvasive evaluation of mitral valve (MV) anatomy and pathology. Transillumination (TI) is a new three-dimensional tool that improves the visualization of cardiac structures due to shadow effects achieved by the use of a virtual light source.We aimed to compare the diagnostic accuracy of TTE TI side by side with standard 3DE (s3DE) display in patients undergoing surgery for MVP. Surgical valve inspection was used as a reference standard, even though surgery allows only static MV assessment.
