Aneurysms of the interventricular membranous septum are a rare anatomical feature that can be detected incidentally on computed tomography or echocardiography. Such aneurysms can pose challenges in the treatment of patients with aortic valve stenosis. A case series of 2 patients with membranous septal aneurysms treated successfully with current-generation balloon-expandable and self-expanding transcatheter heart valves is presented here.

Article Synopsis
  • An 85-year-old woman with severe mitral regurgitation and a history of heart issues underwent a transcatheter repair procedure but encountered a rare complication: interatrial septum dissection with bleeding into the pericardial space.
  • The medical team used an Amplatzer occluder device to address this complication, marking its first application for this issue in this context, and raised concerns about chronic steroid use as a potential risk factor.
  • The use of transoesophageal echocardiography was emphasized as crucial for identifying complications, and decisions regarding closure devices should consider individual patient risks versus conservative management options.

  • Severe tricuspid regurgitation (TR) significantly impacts patients' health status, affecting their symptoms, physical and social functions, and overall quality of life, but may improve with a procedure called transcatheter tricuspid valve replacement (TTVR).
  • The TRISCEND II trial studied 400 patients with severe TR, comparing outcomes of those receiving TTVR combined with optimal medical therapy (OMT) to those receiving OMT alone, using established health status questionnaires.
  • Results showed that patients receiving TTVR+OMT experienced significantly greater improvements in health status at every follow-up, with notable differences in scores indicating enhanced quality of life compared to those who only received

Article Synopsis
  • Aortic valve replacement (AVR) is crucial for patients with severe aortic regurgitation (AR), but some with moderate AR may also face high mortality if untreated.
  • A study analyzed over 81,000 patients with AR to understand how various clinical factors, like left ventricular function and heart dilation, influence mortality risk.
  • The findings indicate that both moderate and severe AR, along with specific cardiac damage markers, significantly increase mortality risk, suggesting a need for further investigation on AVR for those with less severe AR but concerning clinical features.

Article Synopsis
  • Tricuspid regurgitation (TR) is common in patients undergoing transcatheter aortic valve replacement (TAVR), but specific management guidelines are not clearly defined.
  • A study analyzed data from over 312,000 TAVR patients, finding that severe TR correlated with higher mortality rates both in-hospital and at one and three years post-procedure.
  • The research also indicated that a significant number of patients (76.4%) with severe TR improved after TAVR, and several factors predicted this improvement, although ongoing severe TR was linked to increased mortality.

Although, by definition, long noncoding RNAs (lncRNAs) are not translated, they are sometimes associated with ribosomes. In fact, some estimates suggest the existence of more than 50 K lncRNA molecules that could encode for small peptides. We examined the effects of an ethanol and Poly-ADP Ribose Polymerase (PARP) inhibitor (ABT-888) on ribosome-bound lncRNAs.

Nitrofurantoin (NFT) is a commonly used antibiotic for the treatment of urinary tract infections that can cause liver toxicity. Despite reports of hepatic adverse events associated with NFT exposure, there is still limited understanding of the interplay between NFT exposure, its disposition, and the risk of developing liver toxicity. In this study, we aim to develop a physiologically based pharmacokinetic (PBPK) model for NFT in three different species (rabbits, rats, and humans) that can be used as a standard tool for predicting drug-induced liver injury (DILI).
