All subjects underwent venous blood sampling and WES. Regular two-dimensional echocardiography was performed to acquire the following parameters: interventricular septum thickness, left ventricular posterior wall thickness, left ventricular end diastolic diameter, left ventricular end systolic diameter, the maximum thickness of left ventricular walls and left ventricular ejection fraction(LVEF). Full volume images were collected and then off-time analyzed with 3D-STE to acquire global longitudinal strain(GLS), global circumferential strain(GCS), twist and torsion. The relationships between above parameters, genotypes and phenotypes of left ventricle were analyzed. \u0000 \u0000 \u0000Results \u0000Mutations were found in 73% of HCM patients.The two most common genes MYBPC3 and MYH7 accounted for 18% and 15% of mutations respectively.

In ApHCM group, 60% of patients carried genetic mutations, which was significantly lower than non-ApHCM group(84%)(P=0.041). Compared with non-ApHCM group, GLS in ApHCM group was significantly higher (P=0.008). There was no statistical difference of GLS between patients with mutations and without mutations(P=0.068).

All patients underwent routine ultrasound and three-dimensional ultrasound before surgery. According to the St.Gallen criteria, the selected cases were divided into tubes according to the expression of immunohistochemical markers estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER-2). The Luminal epithelial subtype (Luminal subtype), HER-2 overexpression subtype and the triple negative subtype(TN subtype) were used to analyze whether there were differences in the three-dimensional ultrasound characteristics among different molecular subtypes of breast cancer. \u0000 \u0000 \u0000Results \u0000①Three-dimensional gray-scale ultrasound: Luminal subtype breast cancer often showed as an irregular shape of the mass, with burrs on the edges, differential leaves, high echo echoes around and coronal surface convergence. The HER-2 overexpression subtype masses were blurred, with angles, uneven internal echo, and often accompanied by microcalcification. The TN subtype were more clearly mass with more regular edge, slightly enhanced posterior echo. And the differences between the 3 groups were statistically significant (P 0.05). \u0000 \u0000 \u0000Conclusions \u0000Three-dimensional ultrasound imaging combined with two-dimensional ultrasound can better reflect the morphological, blood supply and characteristics of different molecular subtypes of breast cancer, and provide more evidence for the diagnosis and identification of breast cancer before surgery. \u0000 \u0000 \u0000Key words: \u0000Ultrasonography, three-dimensional; Breast cancer; Molecular subtype","PeriodicalId":10224,"journal":{"name":"Chinese Journal of Ultrasonography","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43537544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
