Proteus Mirabilis: An Unlikely Device-Related Infection, Mark A. Colantonio, Michelle Hartzell D.O, Brooke Shannon D.O.

Journal of Community Hospital Internal Medicine Perspectives

Implantable cardiac devices, including cardiac pacemakers, are not without risk for infection, carrying a mortality and morbidity of around 5-15%. Gram positive organisms are most common in 91% of cases, whereas gram negative organisms are less common, found in 2% of cases secondary to gram negative organisms other than Pseudomonas aeruginosa. Here, we present a rare case of the gram-negative organism Proteus mirabilis leading to a pacemaker site infection.

Prepared To Protect: Improving Cardiac Emergency Response Through Education And Action Planning In Youth Club Sports, Melissa Garcia

Nursing | Senior Theses

Sudden cardiac arrest (SCA) is the leading cause of death in youth sports, illuminating the essential demand for adequate emergency response, including cardiopulmonary resuscitation (CPR), automated external defibrillator (AED) usage, and comprehensive emergency action plans (EAPs). Research shows that despite the importance of prompt intervention, the majority of youth club sports programs outside of the school setting lack the training and resources needed to respond effectively to SCA incidents. This study will evaluate the effectiveness of an educational seminar that includes CPR/AED training and EAP simulation exercises in improving participants’ knowledge, skills, and confidence in managing cardiac emergencies. A quasi-experimental …

Early Structural Valve Deterioration And Cusp Tear Leading To Acute Heart Failure In A Second-Generation Trifecta Glide Technology Heart Valve, Akiyoshi Yamamoto, Kenji Kuwaki, Hidekazu Furuya, Yasunori Cho

The Texas Heart Institute Journal

This report highlights a case of early structural valve deterioration with a cusp tear in a second-generation Abbott Trifecta Glide Technology bioprosthetic heart valve. A 70-year-old man had undergone aortic valve replacement with a Trifecta Glide Technology valve 30 months earlier for severe bicuspid aortic valve stenosis. He suddenly developed acute heart failure with dyspnea resulting from severe aortic valve regurgitation, with a cusp tear in the Trifecta Glide Technology valve, as demonstrated by transthoracic echocardiography. The patient was successfully treated with urgent repeat aortic valve replacement.

Pediatric patients with moderate or severe mitral valve regurgitation who had undergone mitral valvuloplasty between September 2016 and August 2023 were included. Kaplan-Meier survival analysis was used to assess freedom from both mitral valve deterioration and cardiovascular death. Univariate and multivariate Cox regression analyses were performed to identify potential …

Contributions Of Pathobiological And Translational Science To Understanding And Managing Ischemic Heart Disease: Progress, Impediments, And Future Directions, L Maximilian Buja

The Texas Heart Institute Journal

Key pathobiological components of ischemic heart disease have been identified as follows: (1) In 1970 to 1973, myocardial infarct size was found to be the primary determinant of prognosis after acute myocardial infarction (AMI); (2) in 1973 to 1989, vulnerable coronary artery plaques were found to predispose individuals to coronary plaque disruption and thrombosis, causing major AMI; (3) in 1972, timely coronary reperfusion was demonstrated to limit the size of evolving AMI but with risk of reperfusion injury; and (4) in 1986, myocardial conditioning was found to be a clinically significant modulator capable of delaying AMI progression. Promising cardioprotective strategies …

Optimal Bag Valve Mask Ventilation Efficacy Of Smart Bag Ventilation Compared To Traditional Adult And Paediatric Bag Valve Ventilation During Cardiopulmonary Resuscitation, Ian Dawson

Theses: Doctorates and Masters

Background: Out-of-Hospital Cardiac Arrest (OHCA) is one of the world’s leading causes of mortality. Survival rates are low, ranging from 3.1–20.4% internationally. The most effective oxygenation method for patients during pre-hospital cardiac arrest is ventilating using a self- inflating Bag-Valve-Mask (BVM). Yet, extensive research has identified a lack of compliance with ventilator guidelines during OHCA cardiopulmonary resuscitation (CPR). As a result, clinicians often ventilate patients too aggressively using the BVM, delivering breaths excessively higher than the International Liaison Committee on Resuscitation (ILCOR) recommended rate of 10 breaths per minute (BPM). Hyperventilation can lead to complications such as aspiration, barotrauma, and …

Incidence Of Bleeding And Performance Of The Precise-Dapt Score In Predicting Bleeding In Patients On Dual Antiplatelet Therapy After Treatment For Acute Coronary Syndrome In Kenya, Peter Mugo, Jeilan Mohamed, Miriam Msunza, James Orwa, Mzee Ngunga

Internal Medicine, East Africa

Introduction: Dual Antiplatelet Therapy (DAPT) plays an important role in the secondary prevention of ischemic events after treatment for acute coronary syndrome (ACS). The long-term use of DAPT is associated with an increased risk of bleeding, which affects morbidity and mortality. Risk stratification scores have been developed to predict this risk and provide a balance against the risk of ischemic events. The aim of this study was to determine the incidence of bleeding in a cohort of patients in Kenya on DAPT and assess the performance of the PRECISE-DAPT Score in predicting the risk of bleeding.

Methods: This was a …

When The Chest And Heart Connect: A Rare Case Presentation Of Left Ventricular Pseudoaneurysm, Victor Delprincipe, Aditya Sharma, Wendy Phillips, Malik Amir, Sanjeev Nair

North Texas Research Forum 2025

We present a rare case of left ventricular pseudoaneurysm (LVPA) resulting from a prior cavity that persisted after surgical treatment of empyema via video-assisted thoracoscopic surgery (VATS) that ultimately lead to chronic inflammation of pericardium, resulting in obtuse marginal artery occlusion causing pseudoaneurysm. Computed tomography angiography (CTA) of the chest suggested that this cavity may have intermittently formed a fistula with the left ventricle, contributing to blood loss and progressive pseudoaneurysm formation. The case highlights the complex interplay between thoracic structures and cardiac pathology in the development of LVPA, with diagnostic and therapeutic challenges addressed.

Rabbit antithymocyte globulin (rATG) is widely used for induction and treatment of acute T-cell mediated rejection in renal transplant patients. Bradycardia is reported as a rare side effect of this medication (citation). With the increasing number of transplanted kidneys in today's world, there is greater need to understand the adverse effects of these drugs in transplant recipients.. Here we report a case of symptomatic bradycardia in a renal transplant patient receiving rATG for acute T-cell mediated rejection.

Optimizing Discharge Education For Patients With Heart Failure, Connie-Rose Pangan

Nursing | Senior Theses

Noncompliance can be a result of a lack of comprehension of discharge instructions and a lack of concise, effective educational resources. Due to this deficit, patients with heart failure are less likely to comply with their discharge protocol and are therefore more likely to be readmitted to the hospital. The aim of the study is to consolidate a teaching method that accommodates one's existing educational barriers, implement follow-up to increase knowledge retention and improve self care, and prevent readmission among HF patients. Two hundred hospitalized, English-speaking patients with heart failure above 65 years old across 20 US Hospitals will be …

Biochemical And Biophysical Properties Of Failing Myocardium In Rare Patient Populations, Gregory Nathaniel Milburn

Theses and Dissertations--Physiology

Heart failure has diverse underlying etiologies, complicating research. While some types, like ischemic disease or inherited mutations, are well-studied, research on rarer forms has lagged. Understanding the molecular drivers in these populations may enhance diagnostics and therapies. This work examines two rare groups: patients with ATTR cardiac amyloidosis and those receiving mechanical assist device support. We show that myocardium from patients with amyloidosis has increased fibrosis and reduced force production without changes in cross-bridge kinetics. Additionally, we show that the passive stiffness of amyloidosis myocardium is not different from non-failing myocardium, indicating increased ventricular wall thickness may cause restrictive filling. …

Tetralogy Of Fallot: Anatomy, Physiology, And Outcomes, Edo Bedzra, Eli Contorno, Herra Javed, Amna Qasim, James St Louis, Taufiek Konrad Rajab

Manuscripts, Articles, Book Chapters and Other Papers

Since the first identification of Tetralogy of Fallot in 1671, consisting of a combination of anatomical defects including biventricular origin of the aorta, maligned ventricular septal defect, overriding aorta, and narrowing or atresia of the pulmonary outflow tract. The first successful operation consisted of a shunt between the left subclavian artery and pulmonary artery. Following this palliative procedure, complete repair is performed once the patient reaches indicative criteria. Since the first attempts at surgical palliation and repair, techniques and outcomes have improved drastically. Definitive repair of Tetralogy of Fallot consists of a multi-patch closure of any Ventricular Septal Defect along …

Abington Jefferson Health Papers

Pulmonary vein stenosis (PVS) is an insidious diagnosis associated with morbidity and mortality. Pharmacologic therapy may suffice initially, but advanced stages demand mechanical intervention. Pulmonary stent implantation (PSI) and pulmonary balloon angioplasty (PBA) are common strategies, both carrying restenosis risks. This meta‐analysis compares PSI and PBA to determine the superior revascularization strategy. We systematically searched databases until November 2023, identifying 11 studies with 780 patients. Studies, including those involving patients undergoing balloon angioplasty (BA) or stent angioplasty (SA) for PVS, were selected. Case reports, editorials, and cross‐sectional studies were omitted. Primary outcomes included restenosis requiring reintervention, 5‐year freedom from restenosis, …
