Fundamental to such capabilities are clearly defined normal ranges. This study aimed to (1) Determine normal ranges for an extensive set of CMR measurements, and the inter-scan reproducibility of these measurements; (2) Determine the impact of common variations in practice, and; (3) Systematically evaluate the findings in the context of published reference ranges. One hundred and 22 healthy adults, including a minimum of 10 males and 10 females per age decile, underwent assessment including CMR (3 T, Siemens). Twenty participants returned for a second CMR. Image analysis was performed using cvi42 by experienced observers. Age- and sex-specific reference ranges, in tabular and normogram formats, and their interscan reproducibility, are provided for left ventricular mass, wall thickness, volumes and ejection fraction; right ventricular volumes and ejection fraction; longitudinal, radial and circumferential LV strains; atrial area, volume and strains; native T1, T2, T2*, aortic distensibility and pulse wave velocity. Measurement reproducibility improved when baseline scans were used for reference, e.g., for basal slice selection. Myocardial T1 was the most reproducible of all CMR measurements. Common variations in practice resulted in significant measurement differences e.g., indexed left atrial volume was larger (47.3 vs 40.3 ml/m², P < 0.0001), and its measurement less variable, when measured from atrial short-axis cine stacks compared to biplanar measurement from 4- to 2-chamber cines. Studies using similar methods to define normal ranges demonstrate clinically-relevant differences in the normal ranges produced. A comprehensive set of age and sex specific CMR reference ranges are provided, along with inter-scan reproducibility and the impact of common variations in practice. Single centre studies, whilst meticulous in design and delivery, result in clinically-relevant variations in normal ranges. We advocate that larger cohorts, including diverse ethnicities, such as the Healthy Hearts Consortium, may be a better approach to defining normal ranges for common CMR measurements.</p>","PeriodicalId":94227,"journal":{"name":"The international journal of cardiovascular imaging","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143733775","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}

Reports have shown that right ventricular dysfunction (RVD) has been associated with increased morbidity and mortality in heart failure (HF) patients. Our goal of this systematic review/meta-analysis is to assess the prognosis of baseline RV function markers including TAPSE (tricuspid annular plane systolic excursion) and TAPSE:PASP (pulmonary artery systolic pressure) ratio after Mitra-clip. MEDLINE and EMBASE were searched from inception to December 20th, 2023, for studies discussing the prognostic outcome of pre-existing RVD in Mitra-clip patients. Definition of RV dysfunction was reported as an abnormal TAPSE (< 15-16 mm) or RV-PA (right ventricle-pulmonary artery) uncoupling expressed as abnormal TAPSE:PASP ratio (< 0.30-0.37 mm/mmHg). We included all original research studies (excluding reviews, meta-analysis, commentaries/editorials, and animal studies) that assessed the prognostic utility of TAPSE and TAPSE:PASP ratio in patients with MR undergoing Mitra-clip. Reviewers independently screened the studies and extracted the pertinent data. Odds ratios (OR) were calculated using a random-effects model. Twelve reports enrolling 3526 patients were included. Mean age ranged from 70 to 81 years and 61.1% patients were male. Primary, secondary, and mixed MR were reported in 36.9%, 61.4%, and 1.8% respectively. Mean LVEF ranged from 27% to 57.1% and 93.7% of patients had MR grade ≥ 3 + (at least moderate to severe MR).
