Real-time three-dimensional transesophageal echocardiography in evaluation of Carpentier's classification of mitral regurgitation / 中国医学影像技术

ABSTRACT

Objective To evaluate the feasibility of real-time threedimensional transesophageal echocardiography (RT3D TEE) in Carpentier's classification of patients with mitral regurgitation (MR).Methods Totally 124 patients with MR were divided into type Ⅰ—Ⅲ type according to Carpentier's classification,and the cases and methods of operation were followed up.Results In all of the 124 patients,9 cases were Carpentier's type Ⅰ,including 8 cases of atrial fibrillation,1 case of mitral valve cleft;102 patients were type Ⅱ,including pure mitral valve prolapse in 16 cases,mitral valve prolapse with chordae rupture in 80 cases,infective endocarditis in 6 cases;13 cases were type Ⅲ,including Ⅲa type rheumatic heart disease in 8 cases,Ⅲ b type of left ventricular systolic dysfunction in 5 cases.Totally 101 cases underwent MR surgery,including mitral valve plasty in 83 cases and valve replacement in 18 cases.Conclusion RT3D TEE is feasible and accurate in defining different types of MR,and it is useful to make management decisions and select the appropriate surgical strategy.
