Key result
Three-dimensional transesophageal echocardiography confirmed the presence of a large cleft within a prolapsing P2 segment that was challenging to diagnose by 2DTEE.
Case Report (n=1)
Three-dimensional transesophageal echocardiography is valuable for accurately diagnosing complex mitral valve pathologies, such as a cleft within a prolapsing segment, which may be challenging to identify with 2D imaging alone.
3D TEE may aid complex mitral cleft detection; leaves open whether routine use alters repair outcomes.
Eighty-year-old woman presented for minimally invasive mitral valve repair for severe mitral regurgitation. Intraoperative two-dimensional transesophageal echocardiography (2DTEE) and subsequent three-dimensional transesophageal echocardiography examination showed severe mitral valve regurgitation with a bidirectional jet caused by both P2 segment prolapse and a large cleft within the P2 segment. The preoperative diagnosis of this complex pathology was challenging by 2DTEE, and a 3D examination of the mitral valve was helpful to confirm the presence of a cleft within the prolapsing segment.

Ramsdell et al. (2018) conducted a case report in Severe mitral regurgitation (n=1). Three-dimensional transesophageal echocardiography (3DTEE) vs. Two-dimensional transesophageal echocardiography (2DTEE) was evaluated on Diagnosis of a cleft within a prolapsing segment. Three-dimensional transesophageal echocardiography confirmed the presence of a large cleft within a prolapsing P2 segment that was challenging to diagnose by 2DTEE.
