Article Abstract
Background: In recent years, triglyceride glucose (TyG) index, as a popular metabolic index, has been proposed as an alternative index of insulin resistance, and it has been proved to be associated with many cardiovascular diseases, but the relationship between it and aortic valve calcification is still unknown.
Methods: A total of 450 aortic valve disease patients were enrolled in this study, including 361 patients with aortic valve calcification (AVC) (calcification group) and 89 patients without (control group). According to the severity of AVC, patients with AVC included severe calcification, moderate calcification and low calcification. The TyG index was calculated based on fasting triglyceride and fasting blood glucose levels.
Results: The TyG index in the calcification group was significantly higher than that in the control group (P < .05), and with the increase of the degree of calcification, the TyG index showed an increasing trend. The univariate and multivariate logistic regression analysis showed TyG index has a high predictive value for the presence of AVC (OR (95% CI): 1.743 (1.036-2.933)) and severe AVC (OR (95% CI): 1.608 (1.143-2.262)). In assessing the predictive value of the TyG index distribution width for AVC, with the first quartile as a reference, the last quartile of the TyG index had significant predictive value for the presence of AVC and severe AVC.
Conclusions: TyG index was significantly associated with the presence and severity of AVC, suggesting that TyG index may be a valid predictor of AVC.

Background: Chronic kidney disease (CKD) is associated with a higher prevalence of valvular diseases and increased mortality from cardiovascular causes. Factors that influence the genesis of cardiac valve calcification (CVC) in these patients are not well-defined.
Objective: To determine the risk factors for valvular calcification in patients with CKD.

Objectives: Failure of vascular closure device (VCD) is the most common cause of access-site vascular complications in transfemoral transcatheter aortic valve implantation (TAVI). The authors sought to determine if the systematic use of arteriotomy-site ballooning with concomitant manual compression following the delivery of a plug-based VCD (MANTA, Teleflex) can optimize toggle-plug assembly apposition to the common femoral artery (CFA) wall and improve the final hemostatic efficacy.
Methods: In this prospective, observational, single-center study, 323 consecutive patients undergoing transfemoral TAVI from October 2021 to December 2024 underwent access closure with the MANTA VCD.
Right coronary artery takeoff plane and implications for brachiocephalic interventions and next generation transcatheter aortic valve intervention embolic protection devices.

Newark Beth Israel Medical Center, Newark, New Jersey.
Objectives: The authors hypothesized that the origin of the right coronary artery (RCA) is a direct continuation of the major aortic arch branches (MAAB) takeoff plane, which may have implications for brachiocephalic interventions and next generation transcatheter aortic valve intervention (TAVI) embolic protection devices (EPDs).
Methods: In this single-center, retrospective, cross-sectional study, the authors analyzed computed tomographic angiography (CTA) images from 92 patients undergoing TAVI evaluation to determine the spatial relationship between the origin of the RCA and the MAAB takeoff plane. Patients with prior cardiothoracic or aortic interventions and those with anomalous RCA origin were excluded.

Objective: This meta-analysis aimed to compare the perioperative safety and efficacy of transcatheter aortic valve replacement (TAVR) versus surgical aortic valve replacement (SAVR) in bicuspid aortic valve (BAV) stenosis.
Methods: We systematically analyzed studies from PubMed, Cochrane Library, Embase, and CNKI comparing TAVR and SAVR in BAV stenosis. Outcomes included postoperative mortality, complications, all-cause survival, and freedom from stroke.
