Patient-Centered Preimplant Education Session And Bi-Weekly Text Message Adherence Reminders In Patients With A Newly Implanted Cardiomems® Device: A Quality Improvement Study, Elizabeth M. Miller, Alicia Abboud, Audrey Cooper

Doctor of Nursing Practice Projects: College of Nursing

Rationale

Heart failure is a deadly disease, affecting over 6.2 million individuals and costing the United States an estimated 30.7 billion dollars (Virani et al., 2020). By 2023, heart failure costs in the United States are estimated to grow to 70 billion dollars with 75-80% of these costs attributed to inpatient hospitalizations (Heidereich et al., 2022). The CardioMEMs® is a small device placed in the patient’s pulmonary artery via a minimally invasive procedure by an interventional cardiologist. The use of remote patient data from the CardioMEMs® device has been shown to reduce hospital re-admissions, facilitate tailored medication management, detect increased …

Late Cardiotoxicity From The Tyrosine Kinase Inhibitor, Dasatinib: Pleural Effusions, Pulmonary Arterial Hypertension, And Right Heart Failure, Mark Jay Zucker, Andrew M. Zucker

The VAD Journal

Despite the remarkable progress made over the past few decades in the management of patients with both solid and hematologic malignancies, radiation- and chemotherapy-related cardiotoxicity remains an ongoing problem. This is true even for newer highly targeted therapies, including tyrosine kinase inhibitors (TKIs). This report presents a case of late/severe right heart dysfunction secondary to pulmonary hypertension, developed after ten years of therapy with dasatinib. We also review the history of this known, but often unrecognized, and potentially reversible complication, and we suggest treatment options. Additionally, this case highlights the remarkable effectiveness of TKIs in patients with chronic myelogenous leukemia …

A Case Report And Review On The Anesthetic Considerations Of Anterior Mediastinal Masses, Carter A. Schulz, Joshua D. Mohs, Andrew M. Reuter

Aesculapius Journal (Health Sciences & Medicine)

Case summary: A 15-year-old female presented with chest pain, dyspnea, and weight loss. A chest X-ray and subsequent CT scan revealed a large anterior mediastinal mass with cervical lymphadenopathy and pericardial effusion. Two biopsies under general anesthesia were performed, with the latter confirming classic Hodgkin lymphoma, nodular sclerosis subtype.

Discussion: This case underscores the significant clinical challenges posed by anterior mediastinal masses due to their proximity to vital cardiovascular and respiratory structures. Physiologic changes during general anesthesia can exacerbate these challenges. Preoperative assessment, including imaging and symptom evaluation, is crucial to guide operative planning. It is key to individualize the …

Ultrasound – An Underutilized Diagnostic Tool For Ventricular Assist Device Driveline Infections, Kristina Krzelj, Tomislav Tokic, Tomislav Kopjar, Maja Cikes, Davor Milicic, Hrvoje Gasparovic

The VAD Journal

Patients with ventricular assist device (VAD) driveline infections (DLI) have reduced quality of life and increased risk of severe complications, such as sepsis, hemorrhagic or ischemic stroke, and wound infections. The management of VAD patients imposes a significant financial burden due to prolonged in-hospital stays, frequent re-admissions, expensive diagnostics, and the need for antibiotic therapy and/or surgical intervention. There is considerable room for improvement in DLI management, particularly in the early detection and treatment stages. Ultrasound, an easily applicable device available in almost every hospital, offers an unrecognized potential for the early detection of DLI. By increasing awareness about the …

Identification And Characterization Of Two Novel Kcnh2 Mutations Contributing To Long Qt Syndrome, Anthony Owusu-Mensah, Jacqueline Treat, Joyce Bernardi, Ryan Pfeiffer, Robert Goodrow, Bright Tsevi, Victoria Lam, Michel Audette, Jonathan M. Cordeiro, Makarand Deo

Electrical & Computer Engineering Faculty Publications

We identified two different inherited mutations in KCNH2 gene, or human ether-a-go-go related gene (hERG), which are linked to Long QT Syndrome. The first mutation was in a 1-day-old infant, whereas the second was in a 14-year-old girl. The two KCNH2 mutations were transiently transfected into either human embryonic kidney (HEK) cells or human induced pluripotent stem-cell derived cardiomyocytes. We performed associated multiscale computer simulations to elucidate the arrhythmogenic potentials of the KCNH2 mutations. Genetic screening of the first and second index patients revealed a heterozygous missense mutation in KCNH2, resulting in an amino acid change (P632L) in the …

Parasympathetic Activity And Bronchial Hyperresponsiveness In Athletes, Audrey Badza

The Downtown Review

Bronchial hyperresponsiveness (BHR) is a term used to describe the bronchial constriction response to environmental stimuli. BHR is increasingly common in endurance athletes due to increased exposure to some stimuli. The purpose of this review is to evaluate Stang et al.'s (2016) article, "Parasympathetic Activity and Bronchial Hyperresponsiveness in Athletes" and discuss the significance of their results. The results concluded that BHR is related to the parasympathetic activity of the heart rather than the pupils. The study concluded that there is an association between BHR and parasympathetic activity of the heart, methacholine is associated with BHR and cardiac vagal activity, …

Abstinence Restores Cardiac Function In Mice With Established Alcohol-Induced Cardiomyopathy, Joshua M. Edavettal, Nicholas R. Harris, Sarah E. Cohen, Janos Paloczi, Bysani Chandrasekar, Jason D. Gardner

School of Graduate Studies Faculty Publications

Alcohol-induced cardiomyopathy (ACM) has a poor prognosis with up to a 50% chance of death within four years of diagnosis. There are limited studies investigating the potential of abstinence for promoting repair after alcohol-induced cardiac damage, particularly in a controlled preclinical study design. Here, we developed an exposure protocol that led to significant decreases in cardiac function in C57BL6/J mice within 30 days; dP/dt max decreased in the mice fed alcohol for 30 days (8054 ± 664.5 mmHg/s compared to control mice: 11,188 ± 724.2 mmHg/s, p < 0.01), and the dP/dt min decreased, as well (−7711 ± 561 mmHg/s compared to control mice: −10,147 ± 448.2 mmHg/s, p < 0.01). Quantitative PCR was used to investigate inflammatory and fibrotic biomarkers, while histology was used to depict overt changes in cardiac fibrosis. We observed a complete recovery of function after abstinence (dP/dt max increased from 8054 ± 664 mmHg/s at 30 days to 11,967 ± 449 mmHg/s after abstinence, p < 0.01); further, both inflammatory and fibrotic biomarkers decreased after abstinence. These results lay the groundwork for future investigation of the molecular mechanisms underlying recovery from alcohol-induced damage in the heart.

Central Activation Of Orl-1 Receptors In Heart Failure Models, Jeffrey Angell

Theses & Dissertations

Heart failure is a prevalent and debilitating disease associated with high morbidity and mortality rates worldwide and is the leading cause of death in the United States. While various therapeutic strategies have been developed and approved to manage heart failure, exploration of novel targets and mechanisms are essential for improving patient outcomes. This thesis investigates the therapeutic potential of the central activation of opioid receptor-like 1 (ORL-1) by nociceptin in a rodent heart failure model.

Furthermore, this study aims to elucidate the central mechanisms underlying nociceptin induced cardiovascular and renal effects in heart failure. This involves investigating neuronal pathways and …

Treatment Of Refractory Ventricular Tachycardia With Radiofrequency Ablation And Temporary Mechanical Circulatory Support, Som P. Singh, Alejandro Vidal Margenat, David L. Boone, Ellen Condoure, Ramesh Hariharan

The VAD Journal

Catheter-based radiofrequency ablation has long been recognized as an effective treatment for refractory ventricular tachycardia (VT). A 57-year-old male with severe coronary artery disease underwent percutaneous mechanical circulatory support because of worsening cardiogenic shock after failed revascularization attempts. Despite aggressive medical management, the patient experienced refractory VT episodes, leading to the decision to proceed with radiofrequency catheter ablation. Notably, the Impella 5.5 device (Abiomed) provided critical left ventricular support during the ablation procedure. This case underscores the potential benefits of Impella support during radiofrequency ablation of complex ventricular arrhythmias.

Atrial Shunt Therapy For Heart Failure: An Update, William Gray

Department of Medicine Faculty Papers

Transcatheter atrial shunt therapies, designed to dynamically lower left atrial (LA) pressure by shunting blood into the larger reservoir of the right atrium and central veins, have been developed as a novel treatment for heart failure (HF) over the past 10+ years. Several atrial shunt devices and procedures are currently in development with several pivotal randomized clinical trials (RCT) underway; however, only 2 sham-controlled RCT (both with the Atrial Shunt Device [Corvia Medical] in HF with EF ≥ 40%) have been reported thus far; a mechanistic RCT (n = 44) that demonstrated a reduction in exercise LA pressure at …

Characterization Of Epithelial Growth Factor Transcripts Identified In Crotalus Atrox Venom, Ivan Lopez, Ying Jia

Research Symposium

Epithelial Growth Factor (EGF) is the primary source in regeneration and stimulation of essential fibroblasts cells commonly found in epithelium. Studies have shown that snake venom components are becoming a growing factor in treating illnesses such as cancer, muscular dystrophy, chronic pain, blood pressure, blood clotting, etc. EGF in human cells contains a promising quaternary structure that can bind to snake venom metalloproteinases, proposing a means of activating biochemical responses through protein-protein interactions to regulate unwanted cellular functions. This supports promising research in achieving a greater understanding of regulation along cellular pathways through ligands, increasing the likelihood of targeting unwanted …

Preparing For The Unexpected: Recognizing A Tortuous Thoracic Aorta During Ultrasound-Guided Thoracentesis, Michael Choi, Jessica Roettger, Christopher J. Smith

Graduate Medical Education Research Journal

Ultrasound-guidance has become the standard of care for bedside thoracentesis. This manuscript describes the importance of utilizing point-of-care-ultrasound (POCUS) and color Doppler in avoiding an unusual, but potentially catastrophic aortic puncture during thoracentesis. The case describes a 70 year-old man who presented with one week of shortness of breath. He was found to have a large left-sided pleural effusion on imaging studies. During a bedside POCUS examination, he was found to have a hyperechoic linear structure in his posterior left hemithorax. Ultrasound application of color Doppler revealed a pulsatile flow, confirming visualization of the aorta. The site of needle insertion …

Partial Support In Chronic Heart Failure, Bart Meyns, Walter Droogne, Steven Jacobs

The VAD Journal

Partial left ventricular assist device (LVAD) support offers several advantages in treating chronic heart failure. It also raises concerns about insufficient support, worsening symptoms, and impediment of myocardial recovery. The clinical trial results for the CircuLite device (Medtronic) have shown that close monitoring can ensure improved outcomes for partial support. Another study on the ovine model demonstrated that partial and full support have similar effects regarding reverse remodeling. Thus, patients receiving partial LVAD support need regular follow-up care. Clinical assessment of symptoms and organ function must be used alongside objective judgment of patients’ needs to ensure support levels are appropriately …

Spontaneous Iliac Arteriovenous Fistula, High-Output Heart Failure, And Cardiac Arrest, J. Maxwell Piraneo, Russell Mordecai, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

High-output heart failure is a potentially life-threatening condition that can lead to cardiac arrest. The most common causes of this condition are obesity, liver disease, arteriovenous shunts, lung disease, and myeloproliferative disorders, however the exact prevalence remains uncertain [1]. Here we describe an unusual case of cardiac arrest as a consequence of high-output heart failure, secondary to rupture of an iliac artery aneurysm into the common iliac vein, with arteriovenous (AV) fistula formation.

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.

Sexual Dimorphism Of Glomerular Capillary Morphology In Rats, Zackarias Coker

Undergraduate Honors Theses

Chronic kidney disease (CKD) progresses faster in males than females; however, the underlying mechanisms remain poorly understood. Sex differences in glomerular capillary morphology has been hypothesized to contribute, in part, to the increased susceptibility to hypertension-induced renal injury and CKD progression in males, but this has not been investigated. The goal of the present study was to assess glomerular capillary morphology in male vs. female rats with intact kidneys and after uninephrectomy (UNX). We hypothesized that glomerular capillary radii (R_CAP) and length (L_CAP) would be greater in male rats.

Male (n=4) and female (n=4) with intact …

Thrompella: Acute Impella Thrombosis During Ecpella Support, Faris Araj, Hurst M. Hall, Amy E. Hackmann

The VAD Journal

We present a case of acute Impella thrombosis during Ecpella support in a 48-year-old man listed for a heart transplant. After two weeks of Ecpella support, echocardiography revealed a 2.6 x 1.1 cm mobile thrombus attached to the Impella inlet (Video). The Impella and attached thrombus were pulled across the aortic valve into the descending aorta and removed without systemic thromboembolism. Due to the ongoing need for left ventricular venting, a new Impella CP was placed.

Quality Assurance In Extracorporeal Membrane Oxygenation Patients, Ruzica Mrkonjic

The VAD Journal

The selection of patients for extracorporeal membrane oxygenation (ECMO) support is a critical component of any perfusion program. Teams must evaluate when to start the support, how long to support the patient, and when is the ideal time to wean. The timing of ECMO support is debated. While some programs emphasize prompt timing, others suggest the conservative approach is better (>7 hours). Delaying ECMO support could increase complications; thus, more evidence has been attained for prompt support. Importantly, complications are common with ECMO support. Despite advances in ECMO support over the last ten years, bleeding remains a high risk. …

The Effects Of Demographics And Risk Factors On The Morphological Characteristics Of Human Femoropopliteal Arteries, Sayed Ahmadreza Razian, Majid Jadidi, Alexey Kamenskiy

UNO Student Research and Creative Activity Fair

Background: Disease of the lower extremity arteries (Peripheral Arterial Disease, PAD) is associated with high morbidity and mortality. During disease development, the arteries adapt by changing their diameter, wall thickness, and residual deformations, but the effects of demographics and risk factors on this process are not clear.

Methods: Superficial femoral arteries from 736 subjects (505 male, 231 female, 12 to 99 years old, average age 51±17.8 years) and the associated demographic and risk factor variables were used to construct machine learning (ML) regression models that predicted morphological characteristics (diameter, wall thickness, and longitudinal opening angle resulting from the …

Delayed Thoracodorsal Artery Perforator Free Flap For Calcaneal Degloving Injury Reconstruction, Mallorie L. Huff, Ahmed M. Mansour, Mamtha S. Raj, Robert J. Allen, Sean J. Wallace

School of Medicine Faculty Publications

The thoracodorsal artery perforator (TDAP) flap has a long vascular pedicle that is ideal for lower extremity reconstruction, but it generally relies on the presence of a dominant septocutaneous perforator vessel. Surgical delay optimizes flap survival by creating relative ischemia to augment perforator vessels. In this report, we describe the use of a delayed free TDAP flap in the setting of an absent dominant perforator vessel for the reconstruction of a calcaneal degloving injury. A 22-year-old actively smoking patient with a body mass index of 33.5 presented with a nonhealing left heel wound with overlying necrotic changes after traumatic degloving …

Recurrent Spontaneous Coronary Artery Dissection: A Case Of Triple Trouble, Sumit Khurana, Jessica Kaushal, Dhruv Markan, John C. Wang, Antony Kaliyadan, Christopher Haas, Amrit Devkota

Journal of Community Hospital Internal Medicine Perspectives

SCAD (Spontaneous Coronary Artery Dissection) is a rare disorder which rarely recurs. It is increasingly diagnosed as a cause for acute coronary syndrome (ACS) with limited insight into its pathophysiology and treatment. Lack of randomized trials and consensus guidelines make this a unique and challenging disease to manage. We describe a complex case of recurrent idiopathic SCAD with prior history of NSTE-ACS (Non-ST elevation Acute Coronary Syndrome) and discuss its management based on current clinical practices.
