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.

Case Description: A 52-year-old male patient with a past medical history of hypertension presented to the hospital for elective left heart catheterization as a part of an evaluation for a …

A Unified Finite Element Framework For Cardiac Growth And Remodeling In Mitral Regurgitation Incorporating Fiber Reorientation And Baroreflex, Mohammad Mehri, Jonathan F. Wenk

Mechanical Engineering Faculty Publications

Mitral regurgitation (MR) triggers complex cardiac remodeling responses that alter the structure and function of the left ventricle (LV). While several models have been developed to predict myocardial growth in MR, they often neglect key concurrent adaptive mechanisms that influence both the pattern and severity of LV dilation. This study presents a unified finite element framework to systematically evaluate the individual and combined contributions of fiber reorientation (FR) and baroreflex regulation to LV growth and remodeling, along with the effects of myocardial material property changes associated with the acute and chronic phases of MR. A healthy baseline model and multiple …

Atrial Fibrillation Detection From At-Rest Ppg Signals Using An Sdof-Tf Method, Mamun Hasan, Zhili Hao

Mechanical & Aerospace Engineering Faculty Publications

At-rest PPG signals have been explored for detecting atrial fibrillation (AF), yet current signal-processing techniques do not achieve perfect accuracy even under low-motion artifact (MA) conditions. This study evaluates the effectiveness of a single-degree-of-freedom time–frequency (SDOF-TF) method in analyzing at-rest PPG signals for AF detection. The method leverages the influence of MA on the instant parameters of each harmonic, which is identified using an SDOF model in which the tissue–contact–sensor (TCS) stack is treated as an SDOF system. In this model, MA induces baseline drift and time-varying system parameters. The SDOF-TF method enables the quantification and removal of MA and …

Relationship Between Exception Request For Higher Listing Urgency And Aggressiveness In Accepting Heart Offers, Jorim Parmar, Yingxian Liu, Devika Adusumilli, Luke Taylor, Shakir Al-Ezzi, Usman Khan, Claudio Bravo, Claudius Mahr, Song Li

North Texas GME Research Forum 2026

BACKGROUND: Transplant programs may submit exception requests to upgrade a listed patient’s priority, often anticipating a higher likelihood of accepting marginal or high-risk donor organs. This study explores whether exception request status is associated with increased risk tolerance in organ acceptance.

METHODS: We conducted a retrospective analysis using data from the Scientific Registry of Transplant Recipients (SRTR), focusing on adult patients (≥18 years) listed for heart transplantation. Statistical analyses were performed using SAS/STAT 14.1. Descriptive statistics summarized demographic and clinical variables. Baseline characteristics were compared between recipients with and without exception requests. Primary analysis: Mixed-effects linear regression was used to …

Cardiac Step-Down Unit (Csu), Two Failures Drive Suboptimal Vte Prevention: Quality Improvement, Jorim Parmar, Shakir Al-Ezzi, Anvi Manduva, Muhammad Suleman, Fahed Alsayed, Debra Medsker

North Texas GME Research Forum 2026

BACKGROUND: In the Cardiac Step-down Unit (CSU), two failures drive suboptimal VTE prevention: (1). over-ordering of SCDs in patients unlikely to benefit and (2). < 10% documented application when SCDs are truly indicated. Baseline data indicates that curbing over-ordering alone would reduce recorded non-compliance by >50%, revealing a clear opportunity for system redesign.

METHODS: To integrate the updated “3 Bucket” Risk Model assessment into the computerized physician order entry (CPOE) in order to delineate the prophylaxis for a given patient population. Once the manual risk assessment proves to be viable in increasing compliance, we can propose having the tool adopted into the CPOE system. Root Cause Analysis revealed that lack of standardized VTE risk stratification leads to inconsistent ordering practices – …

Prognostic Value Of Systemic Inflammatory Indices For Predicting Mace In Nstemi Patients Undergoing Pci, Boney Lapsiwala, Aditya Sharma, Usman Khan, Jorim Parmar, Justin Soloman, Veeranna Vibhuti, Mehdi Khalafi

North Texas GME Research Forum 2026

Background: Cardiovascular diseases (CVD) account for nearly one-third of global mortality, with ischemic heart disease caused by a mismatch between myocardial oxygen supply and demand. Despite advances in percutaneous coronary intervention (PCI) and contemporary pharmacotherapy, patients with non–ST-segment elevation myocardial infarction (NSTEMI) continue to experience substantial residual risk for major adverse cardiovascular events (MACE). As traditional risk stratification tools have limited ability to identify high-risk individuals, interest has shifted toward biomarkers reflecting inflammatory pathways central to atherosclerosis and plaque instability. Hematologic inflammatory markers including pan inflammatory value (PIV), systemic immune inflammation index (SII), neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR) initially …

Double Trouble: A Rare Co-Existence Of Hypertrophic Obstructive Cardiomyopathy And Anomalous Origin Of The Right Coronary Artery, Greeshma Molugu, Srinivasan Rajaganapathy, Seline Haci, Machaiah Madhrira

North Texas GME Research Forum 2026

Introduction: Hypertrophic obstructive cardiomyopathy (HOCM) and anomalous origin of the right coronary artery (RCA) are well-known but rare congenital heart diseases that are recognized as independent leading causes of sudden cardiac death(SCD). The independent prevalence of both these conditions is less than 1%. The co-occurrence of these two conditions is seldom ever reported in the literature. We present an extremely rare case of HOCM and the anomalous origin of the RCA in the same individual.

Background: A 67-year-old male with no significant past medical history presented for chest pain and palpitations. EKG showed atrial fibrillation with rapid ventricular response. Troponin …

Animal Models Of Aortic Aneurysm And Dissection: A Comparative Guide For Mechanism, Therapeutic Testing, And Translational Readouts, Shayan Mohammadmoradi, Sidney W. Whiteheart

Saha Cardiovascular Research Center Faculty Publications

Aortic aneurysms and dissections are devastating vascular diseases with high mortality, yet no pharmacological therapy has proven effective in halting growth or preventing rupture. Surgical and endovascular repair remain the only treatment options for advanced disease. Animal models have been indispensable in defining mechanisms and testing candidate therapies, but the diversity of protocols, strain-dependent variability, and heterogeneous endpoints complicate interpretation and translation. This review provides an update focused on how to match models to specific research questions. We critically compare commonly used abdominal aortic aneurysm (AAA) models (angiotensin II ± hyperlipidemia, elastase, calcium chloride, β-aminopropionitrile BAPN hybrids, and mineralocorticoid agonist/fludrocortisone …

Albuminuria Screening Among Egyptian Patients With Cardiovascular Diseases, Regardless Of Their Diabetic Condition, Amira Fawzy Soliman, Khaled Shelbaya, Wael Abdelatief Mohamed Elhakeem, Osama Louis, Basheer Hafez, Wael Ali, Tarek M.Abdelaziz Elkholy, Baher Emil Ibrahim, Mahmoud M Abdou, Bassem Zarif

Journal of Medicine in Scientific Research

Even in the absence of overt kidney disease, albuminuria is increasingly recognized as a marker of systemic endothelial dysfunction and heightened cardiovascular risk. This prospective cohort study aimed to evaluate whether baseline urinary albumin-tocreatinine ratio (UACR) predicts subsequent incident cardiovascular outcomes among Egyptian adults with cardiovascular disease, regardless of diabetic status.

The Structure Of The Native Cardiac Crossbridge In The Rigor State, Cristina M. Risi, Tyler Nguyen, Betty Belknap, Howard D. White, Jose R. Pinto, Prescott B. Chase, Vitold E. Galkin

Department of Biomedical and Translational Sciences Faculty Publications

Cardiac contraction is driven by double-headed myosin cycling on cardiac thin filaments, where troponin-tropomyosin regulates myosin access to actin. Prior high-resolution structural studies used a single-headed myosin bound to bare actin, thereby limiting insight into coordination between myosin heads and the influence of troponin-tropomyosin on actomyosin interactions. Here, we report a high-resolution structure of the native cardiac rigor cross-bridge formed by heavy meromyosin bound to the thin filament. We show that direct communication between the two bound heads, uneven interactions between the heads and tropomyosin, and spatial constraints imposed by troponin govern myosin placement along the thin filament. Additionally, the …

Combined Snare And Buddy-Balloon Strategy For Failed Valve Crossing In Valve-In-Valve Transcatheter Aortic Valve Replacement, Hira Sarfraz, Muhammad U. Javed, Parth K. Parikh, Joshua A. Cohen, Raymond L. Benza, Matthew R. Summers, Deepak R. Talreja

Department of Medicine Faculty Publications

Background

Retrograde valve crossing during valve-in-valve transcatheter aortic valve replacement (ViV TAVR) may fail despite modern delivery systems.

Case Summary

A 67-year-old man with a degenerated 27-mm Magna Ease bioprosthesis and unfavorable aortic geometry (kinked ascending aorta at a prior surgical graft site) underwent ViV TAVR, where retrograde valve crossing failed despite multiple stiff guidewires and snare traction alone. Successful delivery of a 29-mm Evolut FX+ was ultimately achieved by combining gooseneck-snare traction for coaxial realignment with a partially inflated Tyshak buddy balloon acting as a mechanical ramp across the surgical valve frame.

Discussion

This case demonstrates a structured, stepwise …
