Summary: The study evaluated the outcomes of balloon aortic valvuloplasty (BAV) as rescue or bridge therapy, showing that BAV can improve symptoms and reduce mortality as a bridge to TAVI or rescue procedure. However, patients with poor prognosis may require additional therapies for better long-term outcomes.

Summary: This study evaluated the association between HF-related symptoms and cardiac hemodynamic left ventricular deformations in patients with severe AS. The results showed significant associations between LAVI, LV-GLS, and HF-related symptoms in patients without atrial fibrillation, and the combination of brain natriuretic peptide level, LAVI, and LV-GLS had better diagnostic accuracy.

Summary: The role of the autonomic nervous system in arrhythmias is established and heart rate variability is a useful measurement for its assessment. Artificial intelligence models can use heart rate variability parameters for predicting rhythm disorders, while neuromodulation techniques are increasingly used for treatment. Long-term measurements estimate individual autonomic status, while short-term measurements provide information on triggers of arrhythmias. However, the variability of heart rate variability parameters and the improved treatment of myocardial infarction limit their use for prophylactic implantation of an intracardiac defibrillator. Graphical methods like Poincare plots are important for atrial fibrillation screening, but caution is needed in making inferences about the autonomic nervous system from mathematical models.

Summary: In this pilot study, we found a significant association between reduced DC (<= 2.5 ms) and older age (74 years) in COVID-19 patients, compared to those with a higher DC > 2.5 ms (56.5 years). Reduced DC was also linked to higher levels of inflammatory markers, elevated ferritin, and leukocytosis in patients with COVID-19.

Summary: This study found that circulatory efficiency is significantly reduced in patients with severe aortic valve stenosis (AS), and most patients experience a significant increase in circulatory efficiency after aortic valve replacement (AVR). However, a subset of patients still have reduced circulatory efficiency post-AVR, with less reduction in myocardial fibrosis volume compared to those with restored circulatory efficiency.

Summary: This study aimed to evaluate the short-term effects of thoracic radiotherapy on the autonomic nervous system. Thoracic radiotherapy resulted in cardiovascular autonomic dysfunction by reducing parasympathetic activity and enhancing sympathetic activity. Additionally, the concurrent use of systemic therapies alongside radiotherapy did not significantly amplify or contribute to the alterations in autonomic function in the short-term following thoracic radiotherapy.

Summary: Recognizing symptoms in elderly patients with severe aortic stenosis (AS) can be challenging. This study tested the usefulness of NT-proBNP and Galectin-3 in predicting events in asymptomatic patients with severe AS. The results showed that NT-proBNP was the most reliable predictor of events, and a combination of NT-proBNP and Galectin-3 levels may be vital in the clinical follow-up and decision-making process for these patients.

Summary: Severe low-gradient aortic stenosis (LG-AS) is a common and poor prognosis disease that presents challenges in diagnosis and management. The discrepancy between AV area and pressure gradient raises doubts about the severity of AS and the necessity of AVR. Treatment decisions for severe LG-AS require comprehensive evaluation of both AV and LV and careful estimation of individual benefit and risk.

Summary: Autonomic nervous system dysfunction is a significant characteristic of congestive heart failure patients. This study introduced HRV and MMCA-derived parameters to quantify ANS function in CHF patients and compared their clinical efficacy. The results showed that most parameters improved after treatment in SRHF patients, while only a few showed significant differences in ARHF patients. PNS function and ANS balance were recovered in all CHF patients after treatment. These metrics can be used for prognosis and therapeutic efficacy monitoring.

Summary: This study investigated the role of intracoronary imaging in heart transplant patients with cardiac allograft vasculopathy (CAV). The findings suggest that the presence of fibrotic, lipid, and calcified plaques, as well as the severity of stenosis, are associated with CAV(anglo). High-resolution intracoronary optical coherence tomography (OCT) could potentially improve secondary prevention and outcomes in these patients.

Summary: Newborn mice and humans have temporary cardiac regenerative potential that declines rapidly as they age. Transfer of adult T-cells into neonatal mice after myocardial infarction leads to impaired cardiac regeneration, increased fibrosis, and dysfunction, demonstrating a trade-off between regenerative potential and T-cell development.

Summary: In this study, the researchers found that patients with normal-flow low-gradient aortic stenosis (NFLG-AS) are heterogeneous, with a subgroup resembling patients with high-gradient aortic stenosis (HG-AS) in characteristics and outcomes. Lower gradient NFLG-AS patients have increased long-term mortality, indicating that the use of transcatheter aortic valve replacement (TAVI) for these patients requires careful consideration.

Summary: The aim of this study was to analyze the predictive value of CTA-determined tricuspid annular dilatation (TAD) on the persistence of tricuspid regurgitation (TR) in patients undergoing transcatheter aortic valve replacement (TAVR) for severe aortic stenosis (AS) and concomitant at least moderate TR. The study found that TAD is an independent predictor of TR persistence and is associated with increased 2-year all-cause mortality.
