Two-dimensional echocardiography suboptimally correlate with RV volumes. This study tested whether combination of guideline-directed RV measures in a machine learning (ML) framework improves quantitative assessment of RVEDV and RVEF. RV measurements were obtained on subjects with > mild PR who had cMRI and echocardiogram within 90 days. A gradient-boosted trees algorithm predicted cMRI RV dilation (RVEDV > 160 ml/m²) and RV dysfunction (RVEF<47%), first with \"guideline-only\" measures, and then with \"expanded-features\" to include 44 total echocardiographic, clinical, and demographic variables. Model performance was compared to clinician visual assessment. Of 232 studies (56% tetralogy of Fallot, 20% pulmonary stenosis), the median age was 21.5 years, 21 (9%) had RV dilation, and 42 (18%) had RV dysfunction. For RV dilation prediction, the guideline-only model area under the receiver operating characteristic (AUROC)=0.68, and expanded-features model AUROC=0.85. At 90% sensitivity, the expanded-features model had 73% specificity, 25% positive predictive value (PPV), and 99% negative predictive value (NPV) This was similar to clinician performance (sensitivity 81%, specificity 81%, PPV 29%, NPV 98%). For prediction of RV dysfunction, the guideline-only AUROC= 0.71, additional features did not improve the model, and clinicians outperformed the model.

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). Patients with RVD had a reduction in the overall survival (OS) after Mitra-clip at 6 months (81.8% vs 90.5%, OR = 0.45 [0.35-0.58]; P < 0.001), 1-year (71.1% vs 85.7%, OR = 0.40 [0.33-0.48]; P < 0.001), and 2-year (60.3% vs 76.8%, OR = 0.37 [0.31-0.45]; P < 0.001) compared to normal RV group. Likewise, HF re-admission free survival was minimized among RVD patients at 6 months (76.8% vs 88.1%, OR = 0.47 [0.34-0.65]; P < 0.001), 1-year (64.5% vs 81.3%, OR = 0.44 [0.35-0.55]; P < 0.001), and 2-year (58.2% vs 78.9%, OR = 0.41 [0.30-0.56]; P < 0.001) compared to normal RV group.

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.

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.
