Key result
Ischemic mitral regurgitation is linked to ~7 mm greater maximum leaflet tenting length versus controls.
Why the study?
Geometric changes of the mitral leaflets and annulus in ischemic MR have typically been assessed by 2D echocardiography despite their unique configuration.
Can transthoracic real-time three-dimensional echocardiography quantify geometric changes and valve tenting in patients with ischemic mitral regurgitation compared to controls?
Case-Control (n=22)

Real-time 3D echocardiography effectively quantifies the geometric deformity and tenting of the mitral valve in ischemic mitral regurgitation, providing detailed anatomical insights for surgical planning.
Watanabe et al. (2005) conducted a case-control in Ischemic mitral regurgitation (n=22). Ischemic mitral regurgitation vs. Controls was evaluated on Maximum tenting length (p=<0.0001). Ischemic mitral regurgitation was associated with significantly greater maximum mitral leaflet tenting length compared to controls (9.8 vs 3.1 mm, p<0.0001) using 3D echocardiography.
