We included 292 β-TM patients (151 females, 36.72 ± 11.76 years) consecutively enrolled in the Extension-Myocardial Iron Overload in Thalassemia project and 20 healthy controls (8 females, 36.97 ± 3.54 years). CMR was used to assess FAC and derive LV systolic and diastolic indexes, to quantify myocardial iron overload (MIO) by the T2* technique and LV volumes and ejection fraction, and to detect late gadolinium enhancement (LGE). Healthy subjects and β-TM patients showed comparable LV systolic and diastolic indexes. In β-TM, the LV systolic index was significantly correlated with global heart T2* values, and patients with significant MIO (T2*<20ms) were more likely to have a reduced LV systolic index compared to those without MIO (odds ratio-OR = 3.13; p = 0.013). In multivariate analysis, global heart T2* values and positive LGE emerged as independent determinants of the LV systolic index. The number of segments with LGE inversely correlated with the LV systolic index (p = 0.003). Patients with a reduced LV systolic index were more likely to have cardiac diseases than those with a normal LV systolic index (OR = 5.34; p < 0.0001). No significant correlates were found for the LV diastolic index.

There is limited evidence on the utility of HHUD in assessing aortic stenosis (AS) in real-world settings. Our goal was to validate a new HHUD with CW Doppler assessing AS hemodynamic severity. An observational, single-center study at the Valdecilla University Hospital, Santander, Spain between October 2022 and August 2023 was conducted. Patients previously diagnosed with AS were consecutively recruited. Following a reference echocardiographic examination in the cardiac imaging laboratory by an experienced operator (American Society of Echocardiography, level III), a HHUD with CW Doppler (Kosmos, EchoNous™) was used by an operator with intermediate echocardiography experience (American Society of Echocardiography, level II). The focus was on measuring aortic transvalvular Doppler velocities. Agreement between the mean trans-aortic gradient (mAG) was assessed using the intraclass correlation coefficient (ICC) test. A total of 101 patients were included. The reference test obtained a mAG of 29 mmHg [19.8-42.2], while the HHUD test showed 27.2 mmHg [16.2-43.9]. A strong correlation was observed (r = 0.89), with an ICC value of 0.87 and no significant bias (1.61 ± 0.9). The HHUD demonstrated very good ability to identify severe AS (kappa = 0.81, 95% CI 0.68-0.94; global agreement 92.1%) and good agreement for moderate (kappa = 0.58; global agreement = 80.2%) and mild (kappa = 0.73; global agreement = 88.1%) AS. Agreement was lower in patients with obesity (ICC = 0.63), poor acoustic windows (ICC = 0.74), or atrial fibrillation (ICC = 0.74).

ReCAR-4DPC was performed with identical scan parameters in 15 healthy volunteers (6M,9F, mean [range] 37 [23-47] years) and 11 patients with thoracic aortic dissection (6M,5F, 56 [31-81] years) and acquisition time was recorded. Peak systolic velocity (PSV), average flow (AF) and net forward volume (NFV) were quantified by two readers for ReCAR-4DPC at ascending, descending and diaphragmatic aorta levels. Reference standard 2DPC measurements at the same levels were performed by a separate experienced cardiovascular radiologist. ReCAR-4DPC intra-reader agreement, inter-reader agreement, inter-scan repeatability and concordance with 2DPC-derived metrics (all segments combined) were evaluated with Lin's concordance correlation coefficient (LCCC) and reduced major axis regression.

There were 430 patients with degenerative MR and preserved left ventricular function who underwent cardiovascular magnetic resonance (CMR). MR volume (MRV) and MR fraction (MRF) were categorized as per the ACC/AHA guidelines. Patients were divided into three groups based on category of MRV and MRF: (1) MRV category > MRF category (V > F), (2) MRV = MRF category (V = F), and (3) MRV < MRF category (V < F). Symptoms were defined as shortness of breath, fatigue, and decreased exercise capacity and extracted from chart review. There were 134 (38%) patients who reported symptoms. Based on MRV, 236 (55%), 125 (29%), and 69 (16%) patients had mild moderate, and severe MR respectively.
