Simulating Pacemakers And Heartbeat Recovery Through Mathematical Modeling, Thomas Estrada, Jayla Edwards

Discovery Day - Daytona Beach

Title: Simulating Pacemakers and Heartbeat Recovery Through Mathematical Modeling   This study utilizes the Fitzhugh-Nagumo model to simulate cardiac electrical activity and the regulatory role of pacemakers through ordinary differential equations (ODEs). By defining the rate of change for membrane voltage, 𝑑𝑣/dt, and a recovery variable, 𝑑𝑤/dt, the model captures the heart's excitability and resting states. Central to the analysis is the stimulus current parameter, which represents the "kick" provided by a pacemaker to correct flatline conditions or weak heartbeats. Using Euler’s method for numerical integration, the research compares unstable cardiac rhythms against corrected periodic oscillations. Additionally, the project implements vector …

Improving Outcomes In Pediatric Congenital Heart Disease: The Integration Of Wearable Technology And Ai-Driven Analysis, Sophia Moon, Melissa Cruz, Pad Renga

Research Colloquium

Background: Wearable devices such as biosensors and smartwatches have demonstrated clinical utility in arrhythmia detection in adult populations, but their integration into pediatric congenital heart disease (CHD) care remains limited. Despite advances in CHD management, challenges persist in the timely identification of arrhythmias in children. The use of wearables in pediatrics is constrained by research gaps, adherence issues, and complex data interpretation. Traditional tools like Holter monitors and event recorders face limitations in detecting intermittent arrhythmias and ensuring compliance. These devices cannot leverage artificial intelligence (AI) and machine learning (ML) to enhance ECG interpretation. This study analysis evaluates the potential …

Deprescribing And Polypharmacy In Heart Failure Patients Aged 80 Years And Older: A Case Report, Learsi R. De Hoyos, Elizabeth Mills-Reyes, Chelsea Chang

Research Colloquium

Background: Since 2004, the number of adults aged 65 and older has increased by 5.6%. With a growing geriatric population, medical management should maximize benefits and minimize risks. Polypharmacy, defined as the concurrent use of 5 or more medications, is a common concern in older adults. In adults 80 years and older, the prevalence of polypharmacy is 67.1%. Among adults with heart disease, the prevalence of polypharmacy increased from 40.6% to 61.7% between 2000 and 2018. In the context of heart failure, guideline-directed medical therapy (GDMT) includes beta-blockers, renin-angiotensin-aldosterone system (RAAS) inhibitors, mineralocorticoid receptor antagonists (MRAs), and sodium-glucose cotransporter 2 …

New Onset Heart Failure Of Sodium-Glucose Cotransporter 2 (Sglt2) Inhibitors In Patients With End-Stage Renal Disease (Esrd) And Dialysis, Daiwik Munjwani, Amin Yehya

Cardiovascular Research Symposium

Introduction: Sodium-glucose cotransporter 2 (SGLT2) inhibitors have demonstrated cardioprotective and renoprotective benefits in patients with type 2 diabetes mellitus (T2DM) and chronic kidney disease (CKD). However, the effects of these agents in patients with end-stage renal disease (ESRD) or on dialysis remain underexplored, as previous clinical trials often excluded this population. With the recent removal of ESRD as a contraindication by the U.S. Food and Drug Administration, understanding the cardiovascular risks of SGLT2 inhibitors in this group is imperative. This study aimed to assess the incidence of new onset heart failure (HF), including HF with reduced ejection fraction (HFrEF) and …

This case report highlights the successful application of ICE-guided percutaneous coil embolization for the treatment of aortic pseudoaneurysms, presenting a less invasive alternative for patients for whom traditional surgery poses significant risks.

Case Summary: A patient with a complex cardiovascular history, including aortic root and ascending aorta replacement and CABG x2, developed two pseudoaneurysms below the right coronary button and at the distal aortic graft-native aorta …

Using Atrial Pacing Trials After Tavr To Assess Conduction Abnormalities And Predict Need For Pacemaker Implantation, Hemish M. Philip, Matthew R. Summers, Shirish R. Yasa, Hasani Amir, Daiwik P. Munjwani, Thomas A. Cook, Matthew G. Jackson

Cardiovascular Research Symposium

Abstract:

Background: Transcatheter Aortic Valve Replacement (TAVR) is the standard of care for many patients with severe aortic stenosis who cannot undergo surgical intervention. However, conduction disturbances remain a frequent complication, particularly with self-expanding valves. This often leads to permanent pacemaker implantation (PPI). At Sentara Heart Hospital, atrial pacing at 140 bpm is standard practice during TAVR to assess AV conduction.

Objective: This study aims to evaluate whether preserved 1:1 atrioventricular (AV) conduction during routine atrial pacing at 140 bpm after self-expanding TAVR predicts a low likelihood of requiring PPI, thus yielding a high negative predictive value (NPV).

Methods: We …

Development Of Overt Hypo-Attenuated Leaflet Thickening Following Transcatheter Aortic Valve Replacement, Stephonda Lewis, Hemish M. Philip, Matthew Summers

Cardiovascular Research Symposium

Background: Transcatheter aortic valve replacement (TAVR) is a cornerstone therapy for severe aortic stenosis. Up to one-third of patients develop hypoattenuated leaflet thickening (HALT) within the first year post-TAVR. HALT, a form of leaflet thrombosis, can progress to leaflet immobility and structural deterioration. Despite its significance, no unified approach exists for screening or management of HALT after TAVR.

Case Presentation: A 64-year-old woman presented with shortness of breath on exertion. Exam revealed a 3/6 systolic murmur, and echocardiogram confirmed severe aortic stenosis. She underwent TAVR with resolution of symptoms and was discharged on clopidogrel (Plavix) as single antiplatelet therapy. Two …

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.

Case Presentation and Management:

An 86-year-old woman with prior …

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 …

Effects Of Genetic Polymorphisms On The Oct1 And Oct2-Mediated Uptake Of Atenolol, Mollie Margaret Walton Md, Jonathan Wagner Do, Ceclia E. Villanueva Phd, Bruno Hagenbuch Phd

Research Days

This project characterizes the role of OCT1 and OCT2 on cellular uptake of atenolol and tests the hypothesis that OCT1 and OCT2 proteins with genetic polymorphisms, when expressed in vitro, will result in altered cellular uptake of atenolol relative to the reference genotype. This approach utilizes transiently transfected OCT1 and OCT2 cell assays to perform time-dependent atenolol uptake experiments to generate kinetics information. The goal is to provide a better understanding of polymorphisms associated with OCT1 and OCT2 expression and function as a means to individualize pharmacologic therapy for atenolol.

Duration Of Labor And Umbilical Artery Acidosis In Critical Congenital Heart Disease, Sarah Gwazdacz Md, Teresa Nguyen Bs, Mary Donofrio Md, Faap, Facc, Fase, Timothy Bennett Md, Amanda Mcintosh Md, Faap, Facc.

Research Days

Standard delivery protocols for most prenatally diagnosed CCHD is induction of labor at 39 weeks with aims of a vaginal delivery (VD) near a tertiary care center. There is no benefit to planned Cesarean delivery (CD) over VD for most infants with CCHD. However, longer durations of labor (DOL) in CCHD have been described as a risk factor for umbilical artery (UA) acidosis. We aim to describe the relationship between DOL and UA pH and neonatal outcomes in those with prenatally diagnosed CCHD.

Identifying Unnecessary And Excessive Use Of Intravenous Heparin For The Treatment Of Intermediate-Risk Pulmonary Embolism, Youssef Elfatatry, Ryan Gardner, Chukwuemezie Kamanu, Ruben Rhoades

Health Equity and Quality Improvement (HEQI) Summit

Problem Statement

- Intermediate-risk pulmonary embolism (PE) is a diagnosis with heterogenous presentations and mortality rates ranging from 2% to 15%.

- European Society of Cardiology (ESC) guidelines recommend low-molecular weight heparin (LMWH) as first line therapy in most patients. Despite this, the use of IV heparin in intermediate-risk PE remains widespread, due to uncertainty regarding patients receiving further procedures and mitigation of bleeding risk.

Project AIM:

- We aim to (1) identify prescribing patterns and outcomes of anticoagulant therapy on admission, and (2) propose and implement a "PE Care Pathway" in EPIC to address uncertainty in risk-stratifying and treating …

Assessing Ecg Abnormalities In Pediatric Athletes: A Retrospective Study On Incidence And Implications For Screening Protocols, Arkadeep Ghosh, Mark Gelatt, Lindsey Malloy-Walton, Ashley K. Sherman

Research Days

Background: Utilization of Electrocardiogram (ECG) screening in pediatric athletes remains controversial. The American Heart Association (AHA) hasn't supported the use of mandatory ECG screening for pediatric sports evaluations. The financial burden universal ECG screening in pediatric athletes poses on the healthcare system has supported that screening may not be justified given the low incidence of significant cardiac disease.

Objectives/Goal: This study aimed to examine the incidence, type of ECG abnormalities, and associated risk factors in healthy pediatric athletes.

Methods/Design: A single center retrospective cohort study was conducted on a local male youth competitive soccer program, ages 11-18. Exempt status was …
