本研究的目的，在接受二尖瓣（MV）修复手术的患者中进行，是为了评估三维（3D）经胸（TTE）和经食管（TEE）超声心动图在MV pathology.Background术前评估MV解剖结构的可行性和准确性是必不可少的手术设计在接受MV修复的患者。虽然2维（2D）超声心动图提供了精确的信息，关于MV解剖结构，三维TTE和三维TEE可以增加MV装置和个人scallopidentifiation.METHODS的理解112例严重二尖瓣返流由于MV脱垂进行了完整的2D和3D TTE手术前一天，一个完整的2D和3D TEE在手术室。结果三维超声心动图技术在相对较短的时间内（313 TTE：7 ± 4 min; 3D TEE：8 ± 3 min）是可行的，在大多数情况下，成像质量良好（3D TTE 55%; 3D TEE 35%）和最佳（3D TTE 21%; 3D TEE 45%）。与其他技术相比，三维TEE可以更准确地识别所有MV病变（准确率为95.6%）。三维TTE和2D TEE的准确性相似（90%和87%，分别），而2D TTE的准确性（77%）是显着较低。结论三维TTE和TEE是可行的，有用的方法，在确定MV脱垂的位置。与相应的2D技术相比，它们在病理学描述方面具有上级优势，应被视为标准2D检查的重要辅助手段，用于MV修复的决策。
OBJECTIVES The aim of this study, undertaken in patients who underwent mitral valve (MV) repair surgery, was to evaluate the feasibility and accuracy of 3-dimensional (3D) transthoracic (TTE) and transesophageal (TEE) echocardiography in the evaluation of MV pathology.BACKGROUND A pre-operative assessment of MV anatomy is essential to surgical design in patients undergoing MV repair. Although 2-dimensional (2D) echocardiography provides precise information regarding MV anatomy, 3D TTE and 3D TEE could increase the understanding of MV apparatus and individual scallop identification.METHODS One-hundred-twelve consecutive patients with severe mitral regurgitation due to MV prolapse underwent a complete 2D and 3D TTE the day before surgery and a complete 2D and 3D TEE in the operating room. Echocardiographic data obtained by the different techniques were compared with surgical inspection.RESULTS Three-dimensional techniques were feasible in a relatively short time (313 TTE: 7 +/- 4 min; 3D TEE: 8 3 min), with good (3D TTE 55%; 3D TEE 35%) and optimal (3D TTE 21%; 3D TEE 45%) imaging quality in the majority of cases. Three-dimensional TEE allowed more accurate identification (95.6% accuracy) of all MV lesions in comparison with other techniques. Three-dimensional TTE and 2D TEE had similar accuracies (90% and 87%, respectively), whereas the accuracy of 2D TTE (77%) was significantly lower.CONCLUSIONS Three-dimensional TTE and TEE are feasible and useful methods in identifying the location of MV prolapse. They were superior in the description of pathology in comparison with the corresponding 2D techniques and should be regarded as an important adjunct to standard 2D examinations in decisions regarding MV repair.
