Methods A retrospective study was performed involving ninety consecutive patients with nonobstructive sarcomeric HCM, FC or wild-type ATTR-CM, thirty from each disease, referred to a tertiary cardiomyopathy consultation. Thirty matched healthy individuals served as controls. All participants underwent echocardiographic evaluation of RV morphology and RV myocardial mechanics using 2D-STE. RV global longitudinal strain, RV free wall longitudinal strain, and the RV apical sparing ratio were derived and diagnostic performance of RV parameters for differentiating ATTR-CM, FC, and HCM was assessed using receiver operating characteristic (ROC) curve analysis. Inter- and intra-observer reproducibility was assessed using Bland-Altman analysis. Results RV hypertrophy was significantly more prevalent in ATTR-CM and FC (100% and 97%, respectively) than in HCM (60%). ATTR-CM patients exhibited the most substantial RV strain impairment compared to FC and HCM. RV strain analysis led to significant reclassification of RV systolic dysfunction prevalence in all groups. RV global longitudinal strain, RV free wall longitudinal strain and RV apical sparing ratio emerged as effective parameters for distinguishing ATTR-CM from FC (AUC 0.91, AUC 0.89 and AUC 0.85; respectively). RV wall thickness (RVWT) was the best discriminative parameter for distinguishing ATTR-CM from HCM (AUC 0.98) and FC from HCM (AUC 0.91), followed by RV apical sparing ratio (AUC 0.94 and AUC 0.75, respectively). Excellent inter- and intra-observer agreement was observed. Conclusions Our study underscores the importance of RV assessment in differentiating HCM phenocopies. RV strain parameters and RVWT may play pivotal roles in distinguishing these conditions, facilitating earlier diagnostic and specific treatment initiation. Further research is required to assess their clinical implications.</p>","PeriodicalId":94227,"journal":{"name":"The international journal of cardiovascular imaging","volume":" ","pages":"1855-1867"},"PeriodicalIF":1.5,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148221453","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}

LA structural (LAD, LAVI) and functional parameters (LAEF, εs, εe, εa) were measured. AF patients were divided into AF1 (abnormal LAVI/LAEF, n = 92) and AF2 (normal LAVI/LAEF, n = 21).
