This study has 3 parts. part 1 study population:Subjects(age>_18y)referred for clinically indicated transesophageal echocardiography(e.g exclusion of endocarditis, cardio-embolism,patent foramen ovale,,etc)and found to have no underlying structural cardiac disease or arrhythmia will be included. part 2 study population:consecutive patients with MVP or IMR referred for clinically indicated preoperative transesophageal echocardiography for surgical repair will be prospectively enrolled. part 3 study population:All subjects in part 2 who undergo clinically indicated mitral valve surgery(repair or replacement) will be prospectively enrolled into part3.
Part 1:Any evidence on echocardiography of structural cardiac disease, depressed ejection fraction(<50%),prior history of cardiac surgery, revascularization,revascularization, rheumatic valve disease,or endocarditis;contraindication to transesophageal echocardiography.Part2:AV disease, tricuspid regurgitation more than mild, or pericardial or congenital heart disease;history of MV surgery; endocarditis;in atrial fibrillation at the time of image acquisition.Part 3:Same as Part 2.
