Uhl’S Anomaly: A One And A Half Ventricular Repair In A Patient Presenting With Cardiac Arrest, Reginald Chonoune, Adam Lowry, Karthik Ramakrishnan, Gail D. Pearson, Jeffrey P. Moak, Dilip S. Nath

Pediatrics Faculty Publications

Uhl’s anomaly, first reported in 1952, is an extremely rare congenital cardiac defect characterized by partial or complete loss of the right ventricular myocardium and unknown etiology. Fewer than 100 cases have been described. The response to medical management is poor and there is no known ideal surgical approach or timing for treatment. We report the case of a previously active adolescent male presenting with cardiac arrest, who underwent successful bidirectional cavopulmonary anastomosis (“Glenn” anastomosis) with right atrial reduction and right ventricular free wall plication.

Selective Autonomic Stimulation Of The Av Node Fat Pad To Control Rapid Post-Operative Atrial Arrhythmias., Marco A Mercader, Dingchao He, Aditya C Sharma, Mark C Marchitto, Gregory Trachiotis, Gene A Bornzin, Richard A. Jonas, Jeffrey P Moak

Medicine Faculty Publications

Junctional ectopic tachycardia (JET) and atrial fibrillation (AF) occur in patients recovering from open-heart surgery (OHS). Pharmacologic treatment is used for the control of post-operative atrial arrhythmias (POAA), but is associated with side effects. There is a need for a reversible, modulated solution to rate control. We propose a non-pharmacologic technique that can modulate AV nodal conduction in a selective fashion. Ten mongrel dogs underwent OHS. Stimulation of the anterior right (AR) and inferior right (IR) fat pad (FP) was done using a 7-pole electrode. The IR was more effective in slowing the ventricular rate (VR) to AF (52 +/- …

Routine Screening For Silent Atrial Fibrillation, Zach Stevens

Theses and Graduate Projects

Atrial fibrillation (AF) is the most common arrhythmia and is particularly prevalent in the elderly population. It is associated with an elevated stroke risk which can be easily minimized with anticoagulation. However, AF detection is often difficult due to infrequent or absent symptoms and the first presentation of AF may be a stroke. Advances in technology have made screening for AF more feasible and accessible. Opportunistic screening with pulse palpation and confirmatory ECG is now strongly supported by the evidence and more recent studies have demonstrated that systematic screening – particularly of those with AF risk factors – may be …

Schizophrenia’S Relationship With Cardiovascular Morbidity And Mortality, Hannah Jorgensen

Theses and Graduate Projects

Premature morbidity and mortality due to cardiovascular disease (CVD) disproportionately affects individuals with schizophrenia. This research paper systematically reviews articles that examine the theories and causes of increased CVD risk in individuals with schizophrenia. The findings of the review indicate that there are biological, environmental and sociocultural components of the relationship between schizophrenia and cardiovascular disease. Inflammation from the progression of chronic schizophrenia appears to play a part. The side-effect profile of the medications used to treat schizophrenia cause CVD risk factors. The secondary and tertiary symptoms of the disease process result in problems in motivation, cognitive function and self- …

Incomplete Resolution Of Deep Vein Thromboses During Rivaroxaban Therapy., Jonathan M Yaghoubian, Jacob Adashek, Bahareh Yaghoubian-Yazi, Menachem Nagar, Nojan Toomari, Richard J Pietras, Uri M Ben-Zur

Articles, Abstracts, and Reports

We present the case of a patient with a deep vein thrombosis (DVT) who failed rivaroxaban therapy. Our patient initially presented with left lower extremity edema, erythema, and pain. He was subsequently started on rivaroxaban therapy for a combined treatment period of 12 months, during and after which he persisted to have evidence of a DVT. The patient's prescribed drug regimen was changed from rivaroxaban to warfarin, which demonstrated a rapid resolution of the DVTs as determined by ultrasound assessment of our patient's lower extremity veins. Rivaroxaban, a factor Xa inhibitor, is a well-known oral anticoagulant that is used for …

Interpretation Of Positive Troponin Results Among Patients With And Without Myocardial Infarction., Kristen M Tecson, William Arnold, Tyler Barrett, Robert Birkhahn, Lori B Daniels, Christopher Defilippi, Gary Headden, W Frank Peacock, Michael Reed, Adam J Singer, Jeffrey M Schussler, Stephen Smith, Martin P Than, Peter A Mccullough

Articles, Abstracts, and Reports

Measuring cardiac troponins is integral to diagnosing acute myocardial infarction (AMI); however, troponins may be elevated without AMI, and the use of multiple different assays confounds comparisons. We considered characteristics and serial troponin values in emergency department chest pain patients with and without AMI to interpret troponin excursions. We compared serial troponin in 124 AMI and non-AMI patients from the observational Performance of Triage Cardiac Markers in the Clinical Setting (PEARL) study who presented with chest pain and had at least one troponin value exceeding the 99th percentile of normal. Because 8 assays were used during data collection, we employed …

Assessment Of Coronary Artery Outward Remodeling In Consequence Of Excision Of Epicardial Adipose Tissue In Ossabaw Swine, Kelly Coderre

Undergraduate Honors Thesis Collection

Background

Coronary artery disease (CAD) results from the buildup of cholesterol, inflammatory factors, and proliferating smooth muscle cells within a vessel wall. This plaque impedes on the vessel lumen, decreasing the space through which blood can flow, leading to an array of complications in the human body. To offset these effects, the arterial wall undergoes outward remodeling, a compensatory physiologic phenomenon that blood vessels undertake when burdened with a blockage, such as CAD. In a previously conducted study, a coronary epicardial adipose tissue excision (cEATx) surgery was performed above the left anterior descending (LAD) in Ossabaw swine to investigate the …

Title: Use of personalized patient heart diagrams at the bedside to improve quality of care

Background/Introduction: With congenital heart disease no two hearts are exactly the same. Even with the same lesion, the anatomy of the heart can be completely different. In response to a bedside nursing idea following a cardiac arrest, advanced practice nurses (APN) initiated a program to provide personalized cardiac anatomy diagrams at the bedside of every patient on the cardiology service.

Methods: When a cardiac patient is admitted to cardiology floor, the nurse will check the patients chart for an anatomy picture, then will place …

Pre-Implementation Of A Fontan Post-Operative Clinical Pathway: Summary Of 2016 Pdsa Cycles, Sarah M. Lagergren, Bryan Beaven, Suma Goudar, Megan Jensen

Posters

Background/Introduction: Post-operative hospitalization for the Fontan procedure tends to have an extended hospital length of stay (LOS). From 2013-2014, the average LOS at Children’s Mercy for the Fontan procedure is 14 days, whereas the U.S. national reported average is 11 days. Post-operative management of this patient population is often caregiver dependent. It has been theorized that developing a more standardized post-operative management regimen tailored specifically toward the unique physiology of Fontan patients may be able to improve outcomes and decrease LOS.

Methods: A review of literature was performed and revealed three pediatric institutions have published their post-operative Fontan care guidelines. …

Articles, Abstracts, and Reports

Cigarette smoking causes cardiovascular disease and is associated with poor kidney function in individuals with diabetes mellitus and primary kidney diseases. However, the association of smoking on patients with atherosclerotic renal artery stenosis has not been studied. The current study utilized data from the Cardiovascular Outcomes in Renal Atherosclerotic Lesions (CORAL, NCT00081731) clinical trial to evaluate the effects of smoking on the risk of cardio-renal events and kidney function in this population. Baseline data showed that smokers (n = 277 out of 931) were significantly younger at enrollment than non-smokers (63.3±9.1 years vs 72.4±7.8 years; p

Management Of Penetrating Injury To Thoracic Inlet And Lower Neck With Retained Foreign Body Using Video Assisted Thoracoscopic Surgery, Muhammad Adeel Samad, Hamza Abdur Rahim Khan, Faiza Urooj, Usman Ali Hyder, Fazal Wahab Khan, Saulat H. Fatimi, Jamal Kabeer Khan

Section of Cardiothoracic Surgery

Penetrating neck and chest injuries are a common form of occupational injuries. We hereby report a unique case in which a metallic rod had penetrated the left chest and neck of a plastic factory worker. The patient was vitally stable when he presented to Emergency Room. Chest X-ray was performed and the patient was rushed to the operating room. VATS (video assisted thoracoscopic surgery) and neck dissection was done for retrieval of the metallic rod. On table, endoscopy was also done to rule out injury to oesophagus. No injury to vital structures was found and the subsequent recovery was uneventful.

Validation, Optimization, And Image Processing Of Spiral Cine Dense Magnetic Resonance Imaging For The Quantification Of Left And Right Ventricular Mechanics, Gregory J. Wehner

Theses and Dissertations--Biomedical Engineering

Recent evidence suggests that cardiac mechanics (e.g. cardiac strains) are better measures of heart function compared to common clinical metrics like ejection fraction. However, commonly-used parameters of cardiac mechanics remain limited to just a few measurements averaged over the whole left ventricle. We hypothesized that recent advances in cardiac magnetic resonance imaging (MRI) could be extended to provide measures of cardiac mechanics throughout the left and right ventricles (LV and RV, respectively).

Displacement Encoding with Stimulated Echoes (DENSE) is a cardiac MRI technique that has been validated for measuring LV mechanics at a magnetic field strength of 1.5 T but …

Gastrointestinal Bleeding Events And Statin Use: A Large Propensity Score-Matched Retrospective Cohort Study, Ashley I. Martinez

Theses and Dissertations--Pharmacy

Literature is conflicting regarding the association between statin use and gastrointestinal (GI) bleeding. This study sought to determine whether there is an association between statin use and GI bleeding by comparing incidence of gastrointestinal events between statin users and an active comparator group.

Data was obtained from a large administrative claims database composed of subjects enrolled in a selection of insurance plans throughout the United States from 2009-2014. New statin users (exposed) and thyroid medication users (active comparator, unexposed) were followed from the baseline period (one year prior to medication initiation) until first event, discontinuation, or disenrollment. Subjects were matched …
