Background: Transcatheter aortic valve replacement (TAVR) harbors the risk of periprocedural complications that require emergent cardiac surgery, or "surgical bailout." Surgical bailout intends to be lifesaving but is associated with high mortality. This has given rise to discussion on the necessity of surgical backup during TAVR.

In this study, the binding behavior of β-sitosterol with lysozyme (L) was elucidated by surface plasmon resonance (SPR), computational molecular docking and molecular dynamics simulation studies. Chicken egg white lysozyme (CEWL) served as a model protein. Tri-N-acetylchitotriose (NAG) was used in the redocking experiments to generate precise binding location of the protein.

Article Synopsis
  • Intravascular lithotripsy (IVL) is a new technique aimed at improving stenting in patients with coronary calcification, which can hinder optimal results.
  • A multicenter study analyzed 90 patients with both concentric and eccentric calcium morphologies to determine IVL's efficacy, focusing on outcomes such as angiographic success and fracture presence post-procedure.
  • Results showed that while concentric lesions had more fractures, overall effectiveness in terms of stent expansion and lumen area was not significantly different between the two types of calcium morphology.

  • The study aimed to evaluate the prevalence of high bleeding risk (HBR) characteristics in patients who underwent percutaneous coronary intervention (PCI) and assess the representativeness of the MASTER DAPT trial data.
  • Out of 2,847 patients screened, 38.6% were identified as HBR, but only 9.9% consented to participate in the trial, revealing differences in HBR characteristics between consenting and non-consenting patients.
  • The findings highlight significant selection biases, as the characteristics of HBR patients in the trial differed notably from those in the overall patient population, indicating that trial results may not fully reflect real-world scenarios.

Background: Complete revascularization of the culprit and all significant nonculprit lesions in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) and multivessel disease (MVD) reduces major adverse cardiac events, but optimal timing of revascularization remains unclear.

Objectives: This study aims to compare immediate complete revascularization (ICR) and staged complete revascularization (SCR) in patients presenting with NSTE-ACS and MVD.

Methods: This prespecified substudy of the BIOVASC (Percutaneous Complete Revascularization Strategies Using Sirolimus Eluting Biodegradable Polymer Coated Stents in Patients Presenting With Acute Coronary Syndrome and Multivessel Disease) trial included patients with NSTE-ACS and MVD.

Objective: The primary aim of this research was to harness the capabilities of deep learning to enhance neurosurgical procedures, focusing on accurate tumor boundary delineation and classification. Through advanced diagnostic tools, we aimed to offer surgeons a more insightful perspective during surgeries, improving surgical outcomes and patient care.

Methods: The study deployed the Mask R-convolutional neural network (CNN) architecture, leveraging its sophisticated features to process and analyze data from surgical microscope videos and preoperative magnetic resonance images.

Background: Drug-eluting stents (DES) are considered the therapy of choice in ST-segment elevation myocardial infarction (STEMI); however, a low persistent rate of revascularizations and stent thrombosis exist over the time. We have previously shown that a paclitaxel (PTX)-drug-coated balloon (DCB) after a bare-metal stent (BMS) implantation (DCB-combined strategy) yields superior angiographic and clinical results compared to BMS in the short term. However, the long-term safety and efficacy of this approach remain uncertain.

Article Synopsis
  • Clinical events can occur after percutaneous coronary intervention (PCI), especially in complex cases, and using advanced intracoronary imaging and pressure guidewires may help reduce these risks.
  • The OPTI-XIENCE study is an international, multicenter prospective observational study involving 1,064 patients with specific high-risk characteristics undergoing stent implantation, monitoring them for 12 months.
  • The study aims to evaluate the effectiveness of using these intracoronary tools, with the primary focus on the rate of target lesion failure after one year, while also assessing additional cardiovascular outcomes.

Objective: To assess the efficiency of Dyevert™ Power XT compared to the standard clinical practice when used for percutaneous coronary interventions (PCI).

Methods: A Markov model was developed to estimate, over 3-month cycles and a lifetime time horizon, the cumulative costs and health outcomes (life years gained [LYG] and quality-adjusted life years [QALY]) in a hypothetical cohort of 1,000 patients with chronic kidney disease (CKD) 3b-4 and an average age of 72 years. The incidence of contrast-induced acute kidney injury for these patients is 18.

The aim of this retrospective study is to evaluate the efficacy of a single-dose anakinra during familial Mediterranean fever (FMF) attacks and its effect on the duration, severity, and frequency of attacks. The patients with FMF who had disease episode and received a single-dose anakinra during disease episode between December 2020 and May 2022 were included. Demographic characteristics, MEFV gene variants detected, concomitant medical conditions, demographics of recent and previous episodes, laboratory findings and length of hospital stay were recorded.

Background: Revascularization of left main coronary artery (LMCA) stenosis is mostly based on angiography. Indices based on angiography might increase accuracy of the decision, although they have been scarcely used in LMCA. The objective of this study is to study the diagnostic agreement of QFR (quantitative flow ratio) with wire-based fractional flow reserve (FFR) in LMCA lesions and to compare with visual severity assessment.

  • This study investigates the agreement between fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) in patients with intermediate stenosis in the left main coronary artery (LMCA), finding an 80% concordance between the two methods.
  • The research involved 300 patients and emphasized the role of intravascular ultrasound (IVUS) for assessing cases where FFR and iFR results disagreed, identifying minimal lumen areas as a factor in decision-making.
  • Over a 20-month follow-up, deferral of revascularization based on iFR and IVUS showed a lower incidence of major adverse cardiac events compared to those who underwent revascularization, suggesting that deferring treatment

Article Synopsis
  • The study aimed to evaluate the outcomes of elderly patients (over 75 years) undergoing percutaneous transluminal coronary intervention (PCI) using an antithrombotic strategy that considers their individual risks for bleeding and ischemic events.
  • The research included 1,064 patients and found that the incidence of major adverse cardiovascular events and bleeding was lower in this tailored treatment group compared to a control group, with no cases of stent thrombosis in those receiving shorter dual antiplatelet therapy.
  • The conclusion indicates that a risk-adjusted antithrombotic protocol for elderly patients after revascularization with the latest stent technology may lead to better health outcomes regarding both bleeding and ischemic events.

The amphilimus-eluting stent (AES) is a thin-strut polymer-free stent that releases sirolimus formulated with a carrier from abluminal grooves. The RESERVOIR trial compared AES vs everolimus-eluting stents (EES) in patients with diabetes mellitus (DM) and showed non-inferior neointimal hyperplasia suppression at 9 months follow-up. The aim of this study was to assess comparative clinical outcomes at 5 years.

Aim: Patients with diabetes mellitus are at high risk of adverse events after percutaneous revascularization, with no differences in outcomes between most contemporary drug-eluting stents. The Cre8 EVO stent releases a formulation of sirolimus with an amphiphilic carrier from laser-dug wells, and has shown clinical benefits in diabetes. We aimed to compare Cre8 EVO stents to Resolute Onyx stents (a contemporary polymer-based zotarolimus-eluting stent) in patients with diabetes.
