In this study, we aim to develop a semi-automatic diagnostic network based on deep learning algorithms to detect LVH.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>We retrospectively collected 1610 transthoracic echocardiograms, included 724 patients [189 hypertensive heart disease (HHD), 218 hypertrophic cardiomyopathy (HCM), and 58 cardiac amyloidosis (CA), along with 259 controls]. The diagnosis of LVH was defined by two experienced clinicians. For the deep learning architecture, we introduced ResNet and U-net++\u2009to complete classification and segmentation tasks respectively. The models were trained and validated independently. Then, we connected the best-performing models to form the final framework and tested its capabilities.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>In terms of individual networks, the view classification model produced AUC\u2009=\u20091.0. The AUC of the LVH detection model was 0.98 (95% CI 0.94\u20130.99), with corresponding sensitivity and specificity of 94.0% (95% CI 85.3\u201398.7%) and 91.6% (95% CI 84.6\u201396.1%) respectively. For etiology identification, the independent model yielded good results with AUC\u2009=\u20090.90 (95% CI 0.82\u20130.95) for HCM, AUC\u2009=\u20090.94 (95% CI 0.88\u20130.98) for CA, and AUC\u2009=\u20090.88 (95% CI 0.80\u20130.93) for HHD. Finally, our final integrated framework automatically classified four conditions (Normal, HCM, CA, and HHD), which achieved an average of AUC 0.91, with an average sensitivity and specificity of 83.7% and 90.0%.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>Deep learning architecture has the ability to detect LVH and even distinguish the latent etiology of LVH.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s10554-021-02461-3","type":"journal-article","created":{"date-parts":[[2021,11,10]],"date-time":"2021-11-10T13:02:39Z","timestamp":1636549359000},"page":"759-769","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":40,"title":["Using deep learning method to identify left ventricular hypertrophy on echocardiography"],"prefix":"10.1007","volume":"38","author":[{"given":"Xiang","family":"Yu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinxia","family":"Yao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bifeng","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hong","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6228-5783","authenticated-orcid":false,"given":"Shudong","family":"Xia","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenwen","family":"Su","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuanyuan","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoye","family":"Zheng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2021,11,10]]},"reference":[{"key":"2461_CR1","doi-asserted-by":"publisher","first-page":"1561","DOI":"10.1056\/NEJM199005313222203","volume":"322","author":"D Levy","year":"1990","unstructured":"Levy D, Garrison RJ, Savage DD, Kannel WB, Castelli WP (1990) Prognostic implications of echocardiographically determined left ventricular mass in the Framingham Heart Study.
