Abstract:
Objective:To investigate clinical value of real time three-dimensional transesophageal echocardiography(RT-3D-TEE)in assessing patients with mitral valve prolapse(MVP)combined with mitral regurgitation(MR).Methods:The clinical data of 99 patients with MVP that combined with MR,who admitted to CANGZHOU People's Hospital from February 2020 to October 2023 and were confirmed by RT-3D-TEE,were retrospectively analyzed.According to two dimensional(2D)comprehensive method,they were divided into mild MR group(43 cases)and moderate-severe MR group(56 cases)as the degree of disease condition.The RT-3D-TEE parameters of the two groups were compared.The combined predictive indexes of RT-3D-TEE parameters were obtained by logistic regression analysis.Receiver operating characteristic(ROC)curve was drawn to analyze the values of single and combined RT-3D-TEE parameter in assessing the degree of disease condition of MVP patients with MR.Result:The anterolateral to posteromedial diameter(DAIPm),anterior-to-posterior diameter(DAP),nonplanarity angle(θNPA),annulus area in 3D(A3D),annulus perimeter(AP),total valve leaflet area of mild MR group were respectively(3.20±0.39)cm,(2.82±0.26)cm and(115.77±12.60)°,(6.90±1.28)cm2,(9.36±0.83)cm and(7.71±1.46)cm2,which were significantly less than those[(3.66±0.36)cm,(3.24±0.40)cm,(125.41±13.23)°,(7.99±1.59)cm2,(10.47±1.15)cm and(9.38±1.81)cm2]of moderate-severe MR group,respectively,and the differences of these indicators between two groups were significant(t=6.092,5.965,3.670,3.680,5.333,4.929,P＜0.05).The involution-index of mild group was(26.39±4.39),which was significantly larger than that(22.94±3.65)of moderate-severe MR group(t=4.264,P＜0.05).There were no significant differences in valve annulus height(H),angle of anterior leaflet(θAnt)and angle of posterior leaflet(θPost)between the two groups(P＞0.05).The area under curve(AUC)values of ROC curve of DAIPm,DAP,θNPA,involution-index,A3D,AP and Total valve leaflet area were respectively 0.818,0.831,0.712,0.737,0.704,0.806 and 0.765 in assessing the disease degree of MVP patients with MR.The AUC value of combined detection of them was 0.990.Conclusion:DAIPm,DAP,θNPA,involution-index,A3D,AP and Total valve leaflet area of RT-3D-TEE parameters had a certain value in assessing the disease degree of MVP patients with MR,and the assessment value of combined detection is higher.
