Although TAPSE/PASP has been associated with outcomes across several cardiovascular conditions, its prognostic role in heterogeneous tricuspid regurgitation (TR) populations remains incompletely defined. To evaluate the association between RV-PA coupling, assessed by TAPSE/PASP, and mortality in patients with TR, and to explore whether a composite index integrating longitudinal and areal right ventricular function, (TAPSE × FAC)/PASP, provides incremental prognostic information. In this retrospective cohort study, 247 patients with any grade of TR and available echocardiographic measurements of TAPSE and PASP were included. RV-PA coupling was assessed using TAPSE/PASP, and patients were stratified according to the cohort median. A composite index, (TAPSE × FAC)/PASP, was also evaluated. The primary outcome was all-cause mortality. Cox proportional hazards regression and receiver-operating characteristic analysis were used to assess associations with mortality and discriminatory performance. A pre-specified subgroup analysis was performed in patients with moderate-to-severe TR, defined as EROA ≥ 0.30 cm². Among 247 patients, the median age was 80 years and 61% were female. Reduced TAPSE/PASP was associated with higher 1-year mortality compared with preserved TAPSE/PASP (41.9% vs. 16.3%, p < 0.001) and remained independently associated with mortality after multivariable adjustment (HR 2.15, 95% CI 1.35-3.43, p = 0.001). In the moderate-to-severe TR subgroup (n = 88), TAPSE/PASP retained prognostic significance (HR 2.74, 95% CI 1.42-5.28, p = 0.003). The composite index showed a modest improvement in discrimination compared with TAPSE/PASP alone (AUC 0.691 vs. 0.669). In this retrospective TR cohort, reduced TAPSE/PASP was independently associated with all-cause mortality, with consistent findings in patients with moderate-to-severe TR. The composite (TAPSE × FAC)/PASP index provided only modest incremental discrimination and should be considered exploratory and hypothesis-generating pending external validation.</p>","PeriodicalId":94227,"journal":{"name":"The international journal of cardiovascular imaging","volume":" ","pages":"1881-1890"},"PeriodicalIF":1.5,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13646016/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148255309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods In the first cohort (n = 115), a two-compartment pharmacokinetic model was fitted to dynamic T1 maps acquired after gadolinium administration to predict T1 at 10 min, and sLGE images were simulated from the predicted T1 maps. LGE proportion (LGEp) was quantified from TInull - 60 to TInull + 100 ms, and LGEp was compared. In the second cohort (n = 80), LGEp with TI fixed at 400 ms (LGE400) was compared with conventional LGE using a Look-Locker-derived TI (LGEnull), and these images were visually compared. Results LGEp on sLGE was stable from TInull to TInull + 100 ms, with no significant differences across this range, and LGEp decreased significantly to approximately zero below TInull (p < 0.05). LGEp on sLGE with TI = 400 ms showed strong agreement with that from TInull to TInull + 30 ms (r = 0.979 to 1.0). In the second cohort, LGEp correlated strongly between LGE400 and LGEnull (r = 0.85), with minimal bias on Bland-Altman analysis. In participants without amyloidosis, the correlation further improved (r = 0.96), and both imaging approaches showed similar LGE findings. Conclusion Pharmacokinetically standardized sLGE showed stable LGE proportion above the myocardial null point and reduced LGE proportion below it.

Risk stratification currently relies on luminal stenosis, which poorly predicts thrombotic risk because many events arise from biologically vulnerable plaques with only mild-to-moderate narrowing. Molecular imaging enables non-invasive assessment of the biological processes that drive plaque instability. A structured narrative review of experimental and clinical studies published between 2000 and 2024 was conducted using PubMed and Ovid Embase. Searches related to atherosclerosis, vulnerable plaque, molecular imaging, inflammation, microcalcification, matrix remodelling, angiogenesis, and carotid or coronary disease identified 2,627 records, of which 38 studies were included after screening. Imaging of inflammation and microcalcification shows the greatest clinical maturity, primarily using positron emission tomography (PET). Inflammation is assessed with ¹⁸F-fluorodeoxyglucose (¹⁸F-FDG), reflecting macrophage metabolic activity, while active microcalcification is detected with ¹⁸F-sodium fluoride (¹⁸F-NaF), which binds to hydroxyapatite in early calcific deposits. Imaging of fibrous cap degeneration and angiogenesis remains less clinically mature with limited human validation, including matrix metalloproteinase-targeted single-photon emission computed tomography (SPECT) and integrin-targeted magnetic resonance imaging (MRI) approaches. Translation is limited by technical complexity, cost, and scarce outcome-based validation. Molecular imaging provides biologically informed assessment of plaque vulnerability beyond stenosis alone.

Methods N = 94 patients with acute TTS underwent CMR (median 4 days after admission) and serial blood sampling during the index hospitalization. Patients were stratified by a previously defined prognostic relevant peak high-sensitivity Troponin T cut-off (≥ 28.8× upper limit of normal [ULN] vs. <28.8× ULN).
