Background: Bicuspid aortic valve (BAV) is the most common congenital heart defect in adults, often leading to complications such as thoracic aortic aneurysms and aortic stenosis. While BAV is frequently associated with 22q11.2 deletion syndrome (22q11.

Article Synopsis
- This study investigates how right ventricular (RV) dysfunction affects the outcomes of patients with low-flow, low-gradient aortic stenosis (LFLG-AS) who are undergoing transcatheter aortic valve replacement (TAVR).
- Utilizing data from two Italian centers, it was found that RV dysfunction is linked to a significantly increased risk of all-cause death and major cardiovascular events after one year.
- The findings suggest that assessing RV dysfunction before TAVR can enhance the ability to predict patient prognosis.
The two-dimensional electron gas (2DEG) at the LaAlO[Formula: see text]/SrTiO[Formula: see text] (LAO/STO) interface exhibits gate-tunable superconductivity with a dome-like shape of critical temperature as a function of electron concentration. This behavior has not been unambiguously explained yet. Here, we develop a microscopic model based on the Schrödinger-Poisson approach to determine the electronic structure of the LAO/STO 2DEG, which we then apply to study the principal characteristics of the superconducting phase within the real-space pairing mean-field approach.

Here, epitaxial engineering is used to design and realize a 2DES characterized simultaneously by ferromagnetic order, large Rashba SOC and hexagonal band warping at the (111) interfaces between LaAlO, EuTiO, and SrTiO insulators. The 2DES displays anomalous quantum corrections to the magneto-conductance driven by the time-reversal-symmetry breaking occurring below the magnetic transition temperature.

- The study investigates the significance of cardiac troponin (cTn) levels in predicting mortality in patients with Takotsubo syndrome (TTS), analyzing data from the International Takotsubo Registry.
- It identifies that a cTn increase greater than 28.8 times the upper reference limit signals clinically relevant myocardial injury, correlating with a higher risk of mortality over 5 years (adjusted HR 1.58).
- The findings enhance understanding of patient risk profiles in TTS, emphasizing the need for increased monitoring and follow-up for those with significant troponin elevations.
