Background: Transcatheter aortic valve implantation now has a major role in the treatment of patients with severe aortic stenosis. However, evidence is scarce on its feasibility and safety to treat patients with pure aortic regurgitation.
Aims: We sought to evaluate the results of transcatheter aortic valve implantation using the balloon-expandable SAPIEN 3 transcatheter heart valve (Edwards Lifesciences, Irvine, CA, USA) in patients with pure aortic regurgitation on native non-calcified valves.
Article Synopsis
- Surgical aortic valve replacement (SAVR) is recommended for low-risk patients, while the Heart Team should decide between transcatheter aortic valve implantation (TAVI) and surgery for others, with a preference for TAVI in older patients.
- A multicenter study surveyed 1,049 patients aged 75 and older to understand the role of age and surgical risk in treatment decisions for severe aortic stenosis, finding that TAVI was preferred in 71% of cases.
- The study revealed that as age increases, particularly after 80, the influence of surgical risk scores on treatment decisions decreases significantly, leading most patients to be referred for TAVI even if they have low surgical risk; however, 10%
Article Synopsis
- The COVID-19 pandemic has led to treatment delays for aortic stenosis patients, potentially increasing mortality rates.
- This clinical case series discusses three patients who successfully underwent ambulatory transcatheter aortic valve replacement (TAVR) using a careful selection process and minimalist techniques.
- The ambulatory TAVR approach minimizes the impact of wait times and reduces risks associated with virus exposure and hospital resource use during the pandemic, with no complications noted in a 30-day follow-up.
Introduction: The aim of this study was to evaluate bioimpedance vector analysis (BIVA) for the diagnosis of acute heart failure (AHF) in patients presenting with acute dyspnea to the emergency department (ED).
Methods: Patients with acute dyspnea presenting to the ED were prospectively enrolled. Four parameters were assessed: resistance (R), reactance (Ra), total body water (TBW), and extracellular body water (EBW).
Article Synopsis
- This study investigates the relationship between cardiac magnetic resonance (CMR) late gadolinium enhancement (LGE) and biomarkers linked to myocardial injury and inflammation during acute viral myocarditis.
- It involved 41 patients with a first episode of acute viral myocarditis, measuring peak levels of troponin I, creatine kinase, and C-reactive protein alongside LGE extent to assess correlations and predictive values for clinical outcomes.
- Results showed a significant correlation between peak troponin I and creatine kinase levels with LGE extent, with LGE also serving as an independent predictor of adverse cardiovascular events during a 29-month follow-up period.
