Acquired von Willebrand factor deficiency has been described in patients with aortic valve stenosis due to high shear forces developed during passage through the narrowed valve orifice, which determines structural changes in this molecule. Similar flow conditions are present in patients with an aortic prosthesis that presents a patient-prosthesis mismatch. Patient-prosthesis mismatch is described by the smaller effective orifice area of the prosthesis than the native valve, which would probably determine similar changes in the molecules of the von Willebrand factor, leading to acquiring von Willebrand deficiency.

Aortic stenosis (AS), a progressive valvular disease that results in increasing left ventricular (LV) afterload, leads to ventricular dysfunction and heart failure if left untreated. Transcatheter aortic valve replacement (TAVR) has emerged as a minimally invasive and effective alternative to surgical replacement, especially in elderly or high-risk patients. Objectives: The present study aims to assess the influence of the tricuspid annular plane systolic excursion (TAPSE)/pulmonary systolic arterial pressure (PASP) ratio on clinical outcomes in patients with aortic stenosis undergoing TAVR and offer valuable insights into patient selection and tailored management strategies for individuals undergoing TAVR. Methods: A retrospective analysis was conducted on 100 patients with AS who underwent TAVR, included in two distinct groups based on their median TAPSE/PASP ratio. Results: Patients were divided according to their median TAPSE/PASP ratio into two groups. Those with lower TAPSE/PASP ratios had a higher incidence of post-procedural atrial fibrillation (AF) (48% vs. 28%, p = 0.0404), lower left-ventricular ejection fraction (LVEF) (41.06% vs. 49.50%, p < 0.0001), a more pronounced inflammatory and hematologic response, and longer hospitalization. Receiver-operating characteristic (ROC) analysis demonstrated modest but significant discrimination rather than high sensitivity or specificity for postprocedural arrhythmias, particularly atrial fibrillation. Conclusions: TAPSE/PASP should be regarded as a clinically useful risk-stratification marker in patients with AS undergoing TAVR, enabling the identification of high-risk patients and optimizing peri-procedural management.

Sodium-glucose co-transporter (SGLT) inhibitors are a novel class of glucose-lowering drugs with beneficial pleiotropic effects that have been widely investigated in the past decade in several experimental models and patients in the absence of diabetes. There are two types of transporters: the SGLT1 isoform that is distributed across a broad range of tissues, including the cardiovascular system, and the SGLT2 isoform, which is mostly expressed in renal proximal tubular cells. It is known that inflammation and oxidative stress are key contributors to vascular damage and the progression of atherosclerosis. SGLT inhibitors have demonstrated multiple benefits that contribute to improved vascular health, including alleviation of endothelial function, anti-inflammatory and antioxidative effects, and mitigation of arterial stiffness, all contributing to blood pressure decrease. An increasing body of research has tackled the molecular and cellular mechanisms of their chronic and, more recently, acute cardiovascular beneficial effects. This narrative review specifically delves into the direct vasculoprotective effects of SGLT2 and dual SGLT1/2 inhibitors, summarizing their off-target mechanisms described in various experimental settings (animal models, animal and human cell lines/samples).

Background: Severe aortic stenosis (AS) increases left ventricular afterload and disrupts ventricular–vascular coupling. Transcatheter aortic valve replacement (TAVR) promptly relieves valvular obstruction, but its immediate effects on blood pressure-dependent arterial load and ventricular–vascular interactions are not fully clarified. Estimated pulse wave velocity (ePWV), derived from age and mean arterial pressure, is a convenient surrogate of global arterial load. The study aimed to assess ePWV before and after TAVR and its relationship with ventricular function and inflammatory biomarkers. Methods: In this retrospective observational study, 100 elderly patients with severe AS undergoing TAVR underwent detailed clinical, laboratory, and echocardiographic assessments before and after the procedure. Arterial stiffness was quantified using ePWV, while left ventricular geometry and systolic function were evaluated by standard echocardiography. Post-procedural reassessment was performed at hospital discharge (median 8 days after TAVR). Results: TAVR led to a modest but significant reduction in ePWV (from 12.79 ± 1.54 to 12.39 ± 1.54 m/s, p < 0.01) and improvement in left ventricular ejection fraction (LVEF) (from 44.89 ± 9.2% to 46.7 ± 7.95%, p < 0.01). Higher baseline ePWV correlated with unfavorable left ventricular remodeling and systolic dysfunction, and post-procedural ePWV remained linked to right ventricular performance. Before TAVR, ePWV and LVEF were both associated with inflammatory biomarkers, relationships that disappeared after intervention. Conclusions: Overall, ePWV functioned as an integrated measure of ventricular–vascular interaction and global hemodynamic load, though its interpretation post-TAVR requires caution due to direct blood pressure dependence and confounding by acute procedural inflammation.

Background and Objectives: Despite substantial advances in surgical techniques, anesthesia, and perioperative care, postoperative complications remain a major source of morbidity, mortality, prolonged hospitalization, and healthcare utilization following adult cardiac surgery (CS). Increasing evidence suggests that many of these complications are influenced by modifiable perioperative factors that can be addressed through multidisciplinary care. Materials and Methods: A narrative review was conducted to synthesize current evidence regarding perioperative practices associated with the prevention of postoperative complications in adult CS. A comprehensive literature search of PubMed/MEDLINE, Scopus, and Web of Science identified studies published between January 2015 and April 2026, supplemented by landmark studies and relevant clinical guidelines. Results: The identified evidence was organized into four major domains: infection prevention practices, physiological optimization strategies, protocol adherence and patient safety measures, and organizational and human factors. The strongest evidence supports timely antimicrobial prophylaxis, standardized infection prevention bundles, perioperative glycemic control, maintenance of normothermia, and patient blood management as key interventions associated with improved postoperative outcomes. Surgical safety checklists, standardized perioperative pathways, and adherence to evidence-based protocols further contributed to improved patient safety and consistency of care. Emerging evidence also highlighted the importance of communication, teamwork, safety culture, workload management, and healthcare professionals’ knowledge in facilitating successful implementation of perioperative interventions. Conclusions: Prevention of postoperative complications following CS requires a multidisciplinary, systems-based approach integrating evidence-based clinical interventions with standardized perioperative protocols and effective organizational practices that facilitate consistent implementation of evidence-based perioperative care. Future research should focus on prospective evaluation of integrated perioperative strategies, development of practical risk-stratification models, and further investigation of organizational determinants influencing implementation and postoperative outcomes.
