An Unusual Culprit Behind A Massive Pulmonary Embolism: Atypical May-Thurner Syndrome From Iliac Artery Aneurysm, Boney Lapsiwala, Jiaming Xue, Mayank Singh, Sai Krishan Reddy Dronadula, Sadia Zahid, Mian Yousef

North Texas GME Research Forum 2026

Background: Venous thromboembolism (VTE) is a major cause of global morbidity and mortality. May-Thurner syndrome (MTS) is an iliofemoral venous compression syndrome caused by extrinsic compression of the left common iliac vein (LCIV), classically by the right common iliac artery at the level of the fifth lumbar vertebra. Although the estimated anatomic prevalence ranges from 18-49%, only 2-5% of cases are diagnosed during evaluation for lower-extremity deep vein thrombosis (DVT). Clinical manifestations range from asymptomatic venous compression to unilateral leg swelling, venous insufficiency, and acute iliofemoral DVT, with pulmonary embolism (PE) reported infrequently.

Case presentation: A 75-year-old man with hypertension, …

Faculty, Staff and Student Publications

Background: Despite previously improved survival among children with congenital heart defects (CHDs), U.S. population-level evaluations of survival within recent years are scarce.

Objectives: The purpose of this study was to describe the survival landscape among children with CHDs in a large population-based birth defects registry overall and by CHD lesion.

Methods: This population-based cohort study evaluated 1999 to 2017 live births with ≥1 major CHD in the statewide Texas Birth Defects Registry. Variables included CHD lesion, demographics, gestational age at birth (term/preterm), low birthweight (< 2,500 g at birth), among others. Kaplan-Meier analyses were used to describe survival to 7 days, 28 days, 1 year, 5 years, and 10 years of life. Kaplan-Meier survival estimates were generated for 1-year survival for CHDs overall by lesion, using log-rank tests assessing differences by exposure.

Results: Of 61,656 children with CHDs, survival was 98.1% and 90.7% at 7 days and …

Variables Affecting Neurodevelopmental Outcome In Infants With Critical Congenital Heart Disease, Elizabeth Loughman, Julie Weiner Do, Marcie Files Md

Research Days

Background: The mortality of cardiac conditions in infancy is improving with advances in surgical planning and medical management. Neurologic morbidity remains significant. Clinically correlating an infant with their neurologic exam, MRI/EEG, and subsequent developmental testing remains a challenge. Counseling regarding neurologic outcomes after cardiac intervention is difficult due to the wide range of findings that can sometimes be clinically irrelevant.

Purpose: The goal of this study is to identify factors associated with poor neurodevelopmental outcomes in infants with critical congenital heart defects (CCHD) as assessed by the Bayley Scales of Infant and Toddler Development Edition IV (Bayley).

Methods: This is …

Assessing The Safety And Effectiveness Of Endovascular Treatment Vs. Surgical Repair Of Aortic Aneurysms In Patients With Marfan Syndrome: A Literature Review, Noor Baig, Zainab Mubasher, Nassos Tziviskos, Joseph Pernini, Marcus Fariello, Ryan Hickey

Rowan-Virtua Research Day

Background: This review compares the safety and effectiveness of thoracic endovascular aortic repair (TEVAR) versus open surgical repair in patients with Marfan Syndrome (MFS) and thoracic aortic aneurysms. We assessed differences in mortality, length of hospital stay, renal impairment, and stroke incidence between the two techniques. Currently, open surgical repair is the gold standard treatment.

Hypothesis: As the gold standard treatment, we expect open surgical repair to have more favorable outcomes than TEVAR.

Methods: A systematic literature search was performed using studies from 2000-2024 across PubMed, Scopus, Embase, Cochrane, and Web of Science. Studies were included if they involved adult …

Pediatric Cardiac Xenotransplantation And Expanded Access: Ethical Considerations, Daniel J Hurst, Christopher Bobier, Anthony Merlocco, Luz A Padilla, Daniel Rodger, David Cleveland, John D Cleveland

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Due to the current organ shortage waitlist, alternatives to allotransplantation are necessary. Xenotransplantation is currently being pursued as one such alternative in adults in need of kidney or heart transplantation. Cardiac xenotransplantation of genetically modified pig hearts has been conducted twice in adults under the United States Food and Drug Administration (FDA) expanded access criteria. Because of the shortage of transplantable hearts for children as well as the lack of mechanical circulatory support in this population, pediatric researchers are exploring FDA expanded access in high-risk neonates and infants who lack alternative options for survival. The adult cardiac xenotransplantation experience with …

Effects Of Exercise On The Cardiovascular Health Of Adolescents And Young Adults With Down Syndrome, Samarth Gupta

Rowan-Virtua Research Day

Introduction: It is known that the incidence of Down Syndrome has increased over time and that this condition is associated with congenital heart defects, lower cardiorespiratory capacity, and increased rates of obesity and type 2 diabetes. It has been shown that individuals who have congenital heart defects but not Down Syndrome have increased cardiorespiratory function after engaging in exercise. Unfortunately, the role of exercise in improving cardiovascular health outcomes among individuals with DS is not yet fully understood.

Results: Exercise has been found to improve several health outcomes among individuals with Down Syndrome. For example, moderate to vigorous treadmill exercises …

Investigating The Link Between Preeclampsia/Eclampsia In Mothers And Cardiovascular Risk Among Their Neurodivergent Children, Jasmine Emanuel, Andrea Iannuzzelli, Venkateswar Venkataraman

Rowan-Virtua Research Day

Preeclampsia/Eclampsia are common gestational conditions among pregnant women. These individuals have hypertension after 20 weeks of gestation, proteinuria/end-stage organ disease, and may have seizures. These conditions can put the mother and fetus at risk.^1,2 A review of literature investigates whether an association exists between congenital heart defects (CHD), and maternal preeclampsia/eclampsia in the neurotypical and neurodivergent population. The Rowan-Virtua Regional Integrated Special Needs (RISN) Center patient population was used to investigate whether maternal preeclampsia/eclampsia is indicative of higher congenital heart disease (CHD) in their neurodivergent children to achieve better quality of care.

Inflammatory Marker Levels Among Patients Diagnosed With Autism Spectrum Disorder And Congenital Heart Defects, Patrick Pearce, Venkateswar Venkataraman, Andrea Iannuzzelli, Jennifer Lecomte

Rowan-Virtua Research Day

Autism Spectrum Disorder (ASD) and congenital heart defects (CHD) are conditions that both confer an immense increase in standard of care, and utilization of medical resources addressing comorbidities. One shared symptom that has been consistently cited is inflammation. This review sought to explore the levels of Tumor Necrosis Factor-�� (TNF-��) and Interleukin-6 (IL-6) between patients diagnosed as having either ASD or CHD. By compiling published data containing the mean values of these two inflammatory markers within these populations, it was shown that while both have significantly elevated levels compared to a phenotypically normal demographic, there is no significant difference between …

Is There An Association Between Preeclampsia/Eclampsia And Congenital Heart Disease Among The Neurodivergent Population?, Jasmine Emanuel, Venkateswar Venkataraman, Jennifer Lecomte, Andrea Iannuzzelli

Rowan-Virtua Research Day

Preeclampsia and eclampsia are very common gestational conditions among pregnant individuals worldwide. These individuals are diagnosed with high blood pressure (after 20 weeks of gestation), proteinuria/end-stage organ disease, and may include seizures. These conditions can put the mother and fetus at risk. A review of literature has shown that there is an association between cardiovascular defects among the neurodivergent population, where these individuals have a higher risk of developing atrial septal defects and ventricular septal defects. The Rowan-Virtua Integrated Special Needs (RISN) Center patient population will be used to investigate whether preeclampsia/eclampsia in mothers is indicative of higher congenital heart …

Congenital L-Transposition Of The Great Arteries In A 12-Year-Old: A Case Report, Muhammad Noman

Rowan-Virtua Research Day

Levo-transposition of the great arteries, L-TGA, also known as congenitally corrected transposition, cc-TGA is a rare anomaly and accounts for less than 1% of all congenital heart diseases. It is characterized by both atrioventricular and ventriculoarterial discordance . It is considered a congenitally corrected transposition because the circulation is from right atrium to left ventricle leading to the pulmonary vasculature. The lungs then pump blood into the left atrium to the right ventricle and eventually to the systemic circulation via the aorta.

Development Of A Nurse Practitioner Driven Program For Cardiology Providers To Increase Knowledge And Awareness Of Neurodevelopmental Assessment Needs In Children With Congenital Heart Defects, Michele Readman

Doctor of Nursing Practice Final Manuscripts

Children diagnosed with congenital heart defects are at increased risk for neurodevelopmental delays. Timely referral of patients to a neurodevelopmental clinic for initial evaluation and referrals to support services can improve learning outcomes, provide early intervention for neurodevelopmental disorders, and mediate factors affecting low quality of life. Nationally, a substantial proportion of pediatric cardiologists are not referring children for neurodevelopmental evaluation. A review of patient referrals to a Cardiac Neurodevelopmental Clinic within an urban children’s hospital demonstrated an opportunity to improve provider awareness and knowledge of referral recommendations. Using the Iowa Model of Evidence-Based Practice to Promote Quality Care, an …

A Case Of Protein Losing Enteropathy After Fontan Operation, Gina Kim

Capstone Showcase

Protein Losing Enteropathy (PLE) is a condition in which an excessive amount of proteins are lost through the gastrointestinal tract leading to hypoproteinemia and manifesting as edema, ascites, and diarrhea. While in most cases PLE is a treatable disorder with good outcomes, the morbidity and mortality of the disorder is significantly elevated in patients with a history of Fontan surgery–an operation used to palliate patients born with a single ventricle by rerouting venous blood return directly to pulmonary circulation. After failure of first-line therapeutics of diuretics and steroids, this case study explores the successful treatment of a 5-year-old patient with …

The Role Of Pre-Participation Exams In Identifying Student Athletes At Risk For Sudden Cardiac Arrest, Elizabeth Frey

Honors Projects

Sudden cardiac arrest (SCA) is the leading cause of death in young student athletes (Drezner et al., 2007). With athletes being recognized as some of the healthiest members of society, a catastrophic event like this can stimulate debate over pre-participation screening and appropriate emergency actions. With 55-80% cases of sudden cardiac death (SCD) being asymptomatic before the event (Drezner et al., 2007), looking into how well pre-participation screenings identify at risk individuals becomes much more important. This project investigates to what extent pre-participation physicals (PPE) can be improved to better identify student athletes at risk for sudden cardiac death and …

Derivation And Validation Of A General Predictive Model For Long Term Risks For Mortality And Invasive Cardiovascular Interventions In Congenital Heart Disease, David A. Danford

Capstone Experience: Master of Public Health

Introduction. Accurate assessment of prognosis is a key driver of clinical decision making in congenital heart disease (CHD), but is complicated because CHD represents such a diverse collection of conditions. The aim of this investigation is to derive, validate, and calibrate multivariable predictive models for time to surgical or catheter-mediated intervention (INT) in CHD and for time to death in CHD. Methods. 4108 unique subjects were prospectively and consecutively enrolled, and randomized to derivation and validation cohorts. Total follow up was 26,578 patient-years, with 102 deaths and 868 INTs. Accelerated failure time multivariable predictive models for the outcomes, based on …
