2. Novel Transvalvular Flow Criteria Reduce Indeterminate Stress Echocardiography and Refine Risk Stratification in Low-Gradient Aortic Stenosis.
PMID:日期:2026-09-23Guidelines advocate the use of dobutamine stress echocardiography (DSE) in low-gradient aortic stenosis (aortic valve area [AVA] <1 cm with aortic valve mean gradient <40 mm Hg) with reduced left ventricular ejection fraction (<50%) for subsequent patient management. A significant proportion of patients have nondiagnostic DSE (indeterminate aortic stenosis [AS]). We aimed to assess the impact of DSE on the management of patients with classical low-gradient aortic stenosis and the use of the newly proposed transvalvular flow-based criteria for AS classification. Accordingly, we retrospectively analyzed 287 patients with classical low-gradient aortic stenosis who underwent DSE. Both the conventional (severe AS when AVA <1 cm and aortic valve mean gradient ≥40 mm Hg, moderate AS when AVA ≥1 cm, and indeterminate AS when AVA <1 cm and aortic valve mean gradient <40 mm Hg during stress) and the proposed combined transvalvular flow criteria (severe AS when AVA <1 cm at a flow rate ≥210 mL/s or projected AVA <1 cm) were assessed. After DSE, 84 (29%) patients had severe AS, 81 (28%) had moderate AS, and 122 (43%) had indeterminate AS. Over the median follow-up of 12.0 (interquartile range, 5-33) months, more patients with severe AS (73%) underwent aortic valve intervention compared with those with moderate (40%) and indeterminate AS (44%; <0.001). Use of the newly proposed criteria in the indeterminate AS group improved the proportion of diagnostic tests in the overall population from 57% to 91% and reduced the proportion of indeterminate AS to 9%. Aortic valve intervention was beneficial in patients with reclassified severe AS (HR, 0.50 [95% CI, 0.27-0.92]; =0.03), whereas the benefit was uncertain in the remaining indeterminate AS group (HR, 0.77 [95% CI, 0.22-2.75]; =0.69). After aortic valve intervention, patients with conventionally diagnosed severe AS had a better outcome compared with patients with reclassified severe AS (HR, 2.88 [95% CI, 1.34-6.21]; =0.007). In this real-world study, the transvalvular flow-based criteria for severe AS markedly reduced the number of indeterminate DSE. Within the indeterminate AS group, patients with reclassified severe AS derived benefit from aortic valve intervention.

6. Coronary Inflammation Is Associated With Plaque Progression in Men With HIV.
PMID:日期:2026-09-01People with HIV are at elevated risk for atherosclerotic cardiovascular disease despite viral suppression, suggesting contributions from nontraditional mechanisms. Coronary vascular inflammation may play a role, but its relationship to plaque progression remains incompletely defined. The perivascular fat attenuation index (FAI) score, derived from coronary computed tomography angiography, is associated with vascular inflammation. We evaluated whether coronary inflammation is associated with the incidence and progression of coronary plaque and whether these relationships differ by HIV status. A total of 504 men (n=292 with HIV; n=212 without HIV) from the Multicenter AIDS Cohort Study underwent coronary computed tomography angiography over a median of 4.5 years (3.8-4.9). FAI measurements were performed on baseline scans. Changes in noncalcified, calcified, and total plaque volumes were categorized into tertiles of progression. Associations were estimated using multinomial logistic regression adjusted for interscan time and cardiovascular risk factors. Modified Poisson regression estimated incident plaque. Higher FAI scores in the left anterior descending (LAD) and left circumflex were associated with greater odds of belonging to the highest tertile of noncalcified (LAD odds ratio [OR], 1.83 [1.27-2.64]; left circumflex OR, 2.55 [1.66-3.91]); calcified (LAD OR, 2.62 [1.64-4.18]; left circumflex OR, 3.92 [2.36-6.51]); and total plaque progression (LAD OR, 1.81 [1.25-2.62]; left circumflex OR, 2.65 [1.71-4.10]) among men with HIV, per SD increase in FAI score after adjusting for cardiovascular risk factors, and remained significant after adjustment for baseline plaque. Higher LAD FAI score was associated with incident calcified plaque in men with HIV (RR, 1.21 [1.01-1.46]). Associations for noncalcified and calcified plaque progression were stronger in men with HIV than in men without HIV. Coronary inflammation, assessed by FAI, is independently associated with incident and progressive coronary plaque in men with HIV. These findings support a role for vascular inflammation in accelerated atherosclerosis in people with HIV and highlight FAI as a potential biomarker for risk stratification.

7. Left Ventricular Remodelling in Mitral Valve Prolapse: More Than Volume Overload.
PMID:日期:2026-09-01Left ventricular (LV) remodeling in mitral valve prolapse (MVP) may occur disproportionally to mitral regurgitation (MR) severity, especially in patients with Barlow disease. This study hypothesized an underlying MVP cardiomyopathy, potentially driven by ventricular arrhythmias or a genetic substrate. We investigated the determinants of LV remodeling in patients with MVP beyond MR volume load. Prospective inclusion of patients with nonsyndromic MVP at 3 centers. Patients were scheduled for cardiac magnetic resonance scans, 24-hour Holter monitoring and the presence of an underlying cardiomyopathy-associated genetic variant was assessed. Disproportionate LV remodeling was defined as LV end-diastolic volume above the age- and sex-specific upper limit of normal (LVEDVi) after correction for the total MR volume load, using the following formula: (LV end-diastolic volume-MR volume)/body surface area-LVEDVi >0. A total of 103 patients with MVP were included (58% males, age 52±17 years). Disproportionate LV remodeling was present in 37% and was more frequent in Barlow disease compared with nonclassic MVP (=0.067). After correction for age, sex, and MR volume load, Barlow disease phenotypic features like mitral annular dilatation are independently associated with LV dilatation (<0.001 at multivariable regression analysis for LV end-systolic volume index, =0.518). The total volume load (MR volume+prolapse volume) had a stronger correlation with LV remodeling than MR volume alone. In addition, ventricular arrhythmia-particularly ≥3% premature ventricular contractions-was independently associated with increased LV end-systolic volume index even after correction for other classical risk factors (=0.024, =0.518). None of the patients carried a likely pathogenic or pathogenic variant in cardiomyopathy-associated genes. LV remodeling in MVP is a multifactorial process, where, especially in patients with Barlow disease, the associated mitral annular dilatation and larger prolapse volume drive LV dilatation beyond MR severity. In addition, a burden of ≥3% ventricular ectopy is strongly correlated with LV dilatation and dysfunction. Finally, a monogenic cardiomyopathy substrate appears unlikely.

10. Beyond Doppler: Scalable AI Detection of LVOT Obstruction in HCM.
PMID:日期:2026-09-01Accurate assessment of left ventricular outflow tract (LVOT) gradients is critical for hypertrophic cardiomyopathy management, yet Doppler-based measurements are technically demanding and require expertise. The objective of this work was to develop a multi-view deep learning model capable of classifying LVOT obstruction (>20 mm Hg) using routine 2-dimensional echocardiographic windows without reliance on Doppler imaging. We trained and externally validated a cross-attention-based video-to-video fusion framework that integrated EchoPrime-derived video representations from 3 standard transthoracic echocardiographic views to classify LVOT gradients. Training was performed on a derivation cohort (N=1833) from a tertiary care system in the United States, with model performance evaluated on an internally held-out test set (N=275) and a Korean external validation cohort (N=46). Single-view baselines showed limited discrimination (external area under the receiver operating curves, 0.47-0.70). Conversely, the domain-specific foundational model (EchoPrime) achieved superior single-view performance (area under the receiver operating curves, 0.75-0.80 internal; 0.79-0.83 external), highlighting the importance of echo-specific pretraining and temporal modeling. The proposed multi-view fusion further enhanced predictive performance, with the late fusion model reaching an area under the receiver operating curve of 0.84 on the external cohort with significant population-shift. These results suggest LVOT physiology is encoded in routine 2-dimensional imaging and can be leveraged for clinically relevant gradient classification without Doppler input. The proposed artificial intelligence-guided strategy demonstrates substantial cost savings compared with the screen-all approach. By integrating complementary spatial-temporal information across multiple views, our approach generalizes robustly across populations and may enable real-time decision support, extend LVOT assessment to portable or resource-limited settings, and complement Doppler-based evaluation for longitudinal hypertrophic cardiomyopathy management.
