- W3030330185 abstract "ObjectiveTo study the local morphology of post-infarction ventricular septal rupture (PI-VSR) and the left ventricular function before and after operation and to evaluate the relevant risk factors of death in patients with PI-VSR by using left ventricular opacification (LVO) combined with real-time three-dimensional echocardiography (RT-3DE).MethodsTwenty-eight patients with PI-VSR and 19 patients undergoing surgical treatment were selected. The consistency of two-dimensional ultrasound, RT-3DE and the detection of LVO on the maximum diameter, location, number and shape of ventricular septal rupture (VSR) with the surgical results were compared. Through LVO combined with RT-3DE, the changes of left ventricular function indexes before and after surgery were compared. According to the general data and clinical data of patients, independent risk factors affecting survival and prognosis were explored.Results①There was no significant difference between LVO and RT-3DE in detecting VSR maximum diameter and surgical results (all P>0.05). The location, number and shape of VSR detected by LVO were consistent with the surgical results (all P<0.05). RT-3DE had good consistency in detecting VSR location, shape and surgical results (all P<0.05). Among them, of LVO′s detection of VSR location and shape and the Kappa values of consistence of the intraoperative results were 0.650 and 0.883 respectively. LVO had a sensitivity of 0.923, specificity of 1.000, accuracy of 0.947, positive predictive value of 1.000 and negative predictive value of 0.857 in observing VSR shape. ②LVO combined with RT-3DE was used to evaluate the left ventricular function of postoperative patients. The parameters of left ventricular function improved significantly(all P<0.05). ③The independent risk factors affecting the 30 d survival rate included: gender, Killips pump function classification, and whether or not surgery was performed.ConclusionsLVO and RT-3DE can provide more accurate anatomical information such as VSR maximum diameter, location, number and shape, which provides the basis for the selection of treatment strategy. LVO combined with RT-3DE can evaluate the changes of left ventricular function before and after surgery, which can provide reference for clinical evaluation of prognosis.Key words: Echocardiography, real-time three-dimensional; Ventricular septal rupture; Left ventricular opacification; Risk factor" @default.
