Novel Guidewire Technique For Paravalvular Leak Repair Following Tavr: A Case Report, Daiwik Munjwani, Bharadwaj Chintalapati, Casey Barry, Matthew R. Summers

Cardiovascular Research Symposium

Background:

Paravalvular leak (PVL) is a recognized complication following transcatheter aortic valve replacement (TAVR), associated with increased mortality, heart failure symptoms, and hemolytic anemia. Standard percutaneous PVL closure relies on crossing the defect with a 0.035-inch hydrophilic guidewire, followed by exchange for a stiffer wire to enable device delivery. However, traversing the defect can be technically challenging due to decreased maneuverability of the guidewire. We report a case of PVL repair using a modified 0.014-inch polymer-jacketed coronary guidewire and aspiration guidewire strategy that facilitated stable device deployment and complete leak closure.

Vcd-Induced Model Of Menopause To Study Effects Of Sleep Fragmentation On Atherogenesis, Sarah Shackelford B.S, Alina Moriarty M.S., Basudha Habisyasi M.S., Kathleen Coleman B.S., Pavla Brachova Phd, Diane Duffy Phd, Elena Galkina Phd

Cardiovascular Research Symposium

Introduction: Atherosclerosis is a chronic disease characterized by plaque buildup within arteries, leading to cardiovascular diseases. Sleep fragmentation (SF), defined as less than seven hours of uninterrupted sleep, is a recognized risk factor and is commonly observed in menopausal women. Menopause causes a decline in estrogen and ovarian follicles, resulting in the loss of estrogen’s protective anti-atherogenic effects. SF exacerbates atherosclerosis by promoting oxidative stress and inflammation. Since SF contributes to atherosclerosis, and menopausal women are particularly affected by disturbed sleep, we aim to examine how menopause affects atherogenesis in the conditions of disturbed sleep.

Methods: We used the 4-vinylcyclohexene …

Cyberbullying And Academic Outcomes: Investigating The Mediating Role Of Hookup Site Usage Among Senior High School Students, Rubby Aku Ameh, David Asumadu-Boateng, Jefferson Sigfred Seyaram Bansa, Harry Adjetey Ashong

African Conference on Information Systems and Technology

The proliferation of digital communication technologies has reshaped adolescent interactions, with social media and hookup apps becoming common spaces for connection and exposure to online risks. This study explores the link between cyberbullying via hookup apps and its effects on academic performance and psychosocial well-being among senior high school students in Ghana. Drawing on Social Learning Theory and General Strain Theory, it examines how online victimization influences emotional health and academic outcomes. A mixed methods approach combined survey data from 300 participants with interviews involving 40 students, parents, and school counsellors. Results show 31.7% of students experienced cyberbullying on platforms …

Cybersecurity And Intention To Use Mobile Banking Applications, Ishmael Chikoo, Salah Kabanda

African Conference on Information Systems and Technology

The adoption rate of mobile banking amongst consumers remains low, especially in developing countries where there is a knowledge gap in understanding why consumers do not engage in the frequent use of mobile banking applications. Given that most financial institutions see mobile banking as a strategy for their competitive advantage; it is important that they understand how best to address consumer’s fears brought about by cybersecurity threats. The purpose of this study is to investigate the perceived influence of cybersecurity on the user’s intentions to use mobile banking applications. Data collected from 90 participants was statistically analysed in Smart PLS …

Introduction

Acute coronary obstruction is a rare but potentially fatal complication of transcatheter aortic valve replacement (TAVR), with a markedly increased risk in valve-in-valve (ViV) procedures due to anatomical constraints. The risk is further heightened in patients with complex anatomy, such as low coronary ostia or narrow sinuses of Valsalva. Despite advances in imaging and procedural techniques, pre-procedural risk stratification has remained largely static, relying primarily on pre-procedural imaging with Computed Tomography (CT). Recently, artificial intelligence …
