Challenges Of Thrombectomy In Submassive Pulmonary Embolism With Patent Foramen Ovale, Sana Khan, Syed Ahmed, Muhammad T. Siddique, Edic Stephanian

North Texas GME Research Forum 2026

BACKGROUND/ INTRODUCTION: Submassive, or intermediate-risk, pulmonary embolism (PE) is defined by preserved systemic blood pressure with evidence of right ventricular (RV) strain. The presence of a patent foramen ovale (PFO) in this setting significantly increases the risk of hypoxemia, paradoxical embolization, and procedural complications during catheter-based interventions. Mechanical thrombectomy has become an important treatment option for selected patients with intermediate- to high-risk PE; however, experience in patients with concomitant large PFOs remains limited.

CASE PRESENTATION: A 78-year-old woman presented with acute dyspnea, hypoxemia, and chest pain and was found to have a saddle PE with severe RV dilation and biomarker …

Antibody-Mediated Allograft Rejection 23 Years After Heart Transplant, Jorim Parmar, Boney Lapsiwala, Devika Adusumilli, Sienna Luk, Nguyen Dung, Song Li, Kamala Tamirisa

North Texas GME Research Forum 2026

INTRODUCTION: Orthotopic heart transplantation (OHT) remains the gold standard treatment for patients with advanced heart failure refractory to optimal medical and device-based therapies. Despite advances in perioperative management, immunosuppressive regimens, and long-term surveillance protocols, graft rejection remains a major determinant of post-transplant morbidity and mortality [1]. We report a case, representing one of the longest documented intervals in literature, of suspected antibody-mediated rejection (AMR) occurring 23 years after heart transplantation in which conventional endomyocardial biopsy (EMB) could not be successfully performed. This case highlights the diagnostic uncertainty associated with very late AMR and underscores the potential role of clinical presentation, …

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, …

Don’T Blame The Heart When On Steroids: A Rare Case Of Glucocorticoid Dependant Childhood Asthma Causing Non-Ischemic Dilated Cardiomyopathy, Greeshma Molugu, Srinivasan Rajaganapathy, Machaiah Madhrira, Karthik Anand

North Texas GME Research Forum 2026

Background: Steroids are known to have various cardiac side effects, such as hypertension, left ventricular hypertrophy, myocardial infarction, and sudden cardiac death. They are also known to cause rare but potentially life-threatening cardiomyopathy. The mechanisms behind steroid-induced cardiomyopathy are multifactorial, potentially involving direct or indirect myocardial toxicity, such as tissue fibrosis, apoptosis, and alterations in cardiac remodeling pathways via the renin-angiotensin-aldosterone system. Cardiomyopathy is known to occur with anabolic steroid use, but the literature on glucocorticoid-induced cardiomyopathy is scant. We present a rare case of glucocorticoid-induced dilated cardiomyopathy(DCM) in a patient with a history of refractory asthma who was treated …

A Rare Case Of Successful Resolution Of Bifurcation Stenosis Using Double Kissing Crush Stenting Technique, Greeshma Molugu, Tony Alacron, Karthik Anand, Machaiah Madhrira

North Texas GME Research Forum 2026

Introduction: Bifurcation lesions are associated with greater procedural complexity and consequently are at higher risk for stent restenosis. Bifurcation lesions are still technically challenging even in the era of modern stents. High incidence of restenosis both in the main vesseI and side branch Iimits the Iong-term prognosis. We present a rare case of successful resolution of bifurcation stenosis in a patient by using the double kissing (DK) crush stenting technique.

Nursing | Senior Theses

Background: Cardiovascular disease is the leading cause of death in the United States, affecting African American adults at higher rates compared to other racial and ethnic groups. Diabetes as a comorbidity is one of the risk factors of experiencing a myocardial infarction, remaining one of the leading causes of death among individuals with diabetes. Objective: To examine the effectiveness of structured diabetes education tailored to African American adults who are at risk for and after a myocardial infarction. Additionally assessing the complications of a myocardial infarction, the outcomes associated with structured education will be compared to the outcomes of …

Modulating Oran Nitrate-Reducing Bacteria To Enhance Nitric Oxide Bioavailability As A Therapeutic Target For Atherosclerosis, Donovan C. Davidson

CMC Senior Theses

Atherosclerosis remains the primary driver of global cardiovascular disease, yet clinical interventions are largely restricted to high-cost, invasive procedures only after it has reached a critical stage. Recent research has identified a connection between the oral microbiome and vascular health via the enterosalivary nitrate-nitrite-nitic oxide (NO) pathway. Oral nitrate-reducing bacteria (ONRB) drive the synthesization of NO by reducing dietary nitrate into nitrite, which is then converted into bioavailable NO. NO is a potent vasodilator that maintains endothelial health by suppressing inflammation through inhibiting the expression of adhesion molecules VCAM-1 and ICAM-1. However, this pathway is easily compromised by dysbiotic oral …

A Tale Of Two Serpins: Pathologic And Protective Roles Of Agt And Pai-1 In Metabolic And Cardiovascular Disease, Alex C. Pettey

Theses and Dissertations--Physiology

Metabolic and cardiovascular diseases are leading causes of morbidity and mortality worldwide. Conditions such as metabolic dysfunction-associated steatotic liver disease (MASLD), aortic aneurysm, and cardiac fibrosis have limited pharmacological therapies, underscoring the need for deeper mechanistic investigations. Serine protease inhibitors (serpins) have been implicated in these pathologies and represent potential therapeutic targets. Despite structural homology, serpins regulate diverse physiological processes through both protease inhibition and non-inhibitory mechanisms. This dissertation examines the roles of two serpins, angiotensinogen (AGT) and plasminogen activator inhibitor-1 (PAI-1), in preclinical models of metabolic and cardiovascular disease to identify novel mechanisms that may inform future therapeutic strategies. …
