Dynamic Left Ventricular Obstruction Post Transcatheter Aortic Valve Replacement (Tavr): The “Suicide Lv” Phenomenon, Brian Chen

Rowan-Virtua Research Day

• The transcatheter aortic valve replacement (TAVR) has become a relatively common treatment option for aortic stenosis, especially given the growing number of older patients with severe degenerative aortic stenosis

• While the procedure is overall very safe, there are still a number of potentially serious complications including bleeding, stroke, and cardiac tamponade. One rare complication is a dynamic left ventricular obstruction post valve deployment, which has been called the “Suicide LV” phenomenon.

• Rapid hemodynamic compromise resulting from this can result in significant morbidity and mortality if not diagnosed in time.

• Given the increasing frequency of patients undergoing …

Case Report: Post-Partum Headache, Alaleh Ebrahimi

Rowan-Virtua Research Day

Cerebral venous sinus thromboses are rare and occur in 5 people/1,000,000, more commonly in women that are pregnant at about 202/100,000 deliveries with an 11.63% mortality rate. It is believed that pregnancy being a hypercoagulable state is one of the main reasons that it is more common in pregnant and post-partum women. Common symptoms include sudden onset headache, blurry vision, focal neuro deficits, seizures and altered mental status.

The Application Of Point-Of-Care Ultrasound In Ed Intubations And Airway Access: A Systematic Review, Frank Wheeler, James Espinosa, Alan Lucerna, Jeffrey Gardecki

Rowan-Virtua Research Day

Intubation is an essential procedure performed on a routine basis in the emergency room. Unsuccessful intubations are associated with deleterious outcomes. A systematic review was performed to investigate the accuracy of point of care ultrasound (POCUS) in successful Endotracheal Tube (ET) tube confirmation, utilizing ultrasonography, identification of the cricothyroid membrane utilizing ultrasound, and dynamically during use of ultrasonography in the process of intubation. This review demonstrated high sensitivity and specificity for ultrasound confirmation of ET tube placement, high success rate in ultrasound-guided intubation, and lower than expected accuracy in identifying the cricothyroid membrane. Ultrasonography should be considered for ET tube …

Spontaneous Conus Medullary Infarction In The Absence Of Cardiovascular Risk Factors, Bavica Gummadi, Jaffer Ahmed, Swarna Rajagopalan

Rowan-Virtua Research Day

Spinal cord infarction (SCI) is rare and most often occurs in individuals with predisposing cardiovascular risk factors and traumatic injuries

As there are no distinct diagnostic criteria for SCI, diagnosis is difficult in patients presenting without predisposing factors and is often mistaken for transverse myelitis.

Delay in early diagnosis contributes to the high case fatality rate of SCI.

This case highlights the importance of including SCI in the differential of a patient with acute paraparesis even in the absence of co-existing risk factors.

Retrograde Thromboembolism From The Proximal Descending Thoracic Aorta Leading To Recurrent Acute Cerebrovascular Events, Mark Staroelsky, Akash Patel, Gregory Holland, Nishant Parikh, Peter Bulik

Rowan-Virtua Research Day

In the United States, approximately 800,000 individuals experience a stroke every year

Nearly 25% of strokes are recurrent

Cryptogenic strokes, or those with unknown causes after testing, make up a significant portion of ischemic strokes, as many as 32%

Retrograde thromboembolic events originating from the proximal descending thoracic aorta should be considered as a potential etiology in cryptogenic strokes

The appropriate management of embolic events from aortic atheroma needs further research

Here, we present a case of a 55-year-old male who had recurrent cryptogenic strokes whose origin was discovered to stem from retrograde embolic phenomena from atheroma located within the …

Alteplase Used In A Child With An Acute Ischemic Stroke, Shah Nawaz Chaudhary, James Espinosa, Alan Lucerna, Adam Richards

Rowan-Virtua Research Day

Stroke, also known as cerebrovascular accident (CVA), is a neurological injury caused by inadequate brain perfusion due to either ischemia or hemorrhage. There is an abundance of literature on the management of ischemic strokes in adults and this has led to well-defined diagnostic and treatment guidelines. However, the management of pediatric ischemic strokes is currently based on clinical experience of experts, recommendations of consensus guidelines, case studies and extrapolation from adult clinical trials. In this case report, a pediatric patient suffering from an ischemic stroke is successfully treated with IV alteplase (tPA).

Atypical Presentation Of Non-Aneurysmal Subarachnoid Hemorrhage, Aleks Spirollari, James Espinosa, Kevin Dwyer

Rowan-Virtua Research Day

When most clinicians think of subarachnoid hemorrhages (SAH), they think of “most severe headache of my life” as the most common chief complaint. However, it is only reported in about 70% of patients with SAH. Other symptoms may include nausea and/or vomiting, stiff neck, visual disturbances, loss of consciousness, weakness, and seizures. Patient history may involve previous SAH, hypertension, oral contraceptives in women, recent trauma, family history of intracranial aneurysms, history of smoking, alcohol, and drug use. However, there are atypical causes of SAH that may be missed upon initial evaluation for patients that may not have the above mentioned …

Acute Flecainide Toxicity Treated With Intravenous Lipid Emulsion, Joseph S. Schreiner

Rowan-Virtua Research Day

Flecainide is a Vaughn-Williams class IC antiarrhythmic used in the treatment of supraventricular tachycardias including atrial fibrillation. While overdose is rare, its negative effects on cardiac inotropy and conduction pathways can be readily fatal. This is further complicated by the redistribution of the drug out of the plasma and deposition in tissue, rendering reversal by sodium bicarbonate (the standard first line treatment agent) relatively ineffective. A case study of the successful treatment of hemodynamic collapse using sodium bicarbonate in conjunction with intravenous lipid emulsion (ILE) in a patient who ingested a large amount of flecainide in a suicide attempt will …

An Unusual Ed Case: Aortic Aneurysm Presenting As Chf Exacerbation, Darren Finn, James Espinosa, Russell Mordecai, Kishan Patel

Rowan-Virtua Research Day

There has been a significant increase in the incidence of thoracic aortic aneurysms, currently making aneurysmal disease the 18th most common cause of death within the United States. This disease is typically an insidious one, with the aorta growing an average of only 0.1 cm per year. Consequently, most patients remain asymptomatic until late stages of the disease when dissection or worse, rupture has occurred. Under extremely rare circumstances, thoracic aortic aneurysms can present clinically due to mass effect. Airway, esophageal and vascular compression, secondary to aortic arch dilation has been previously documented. The condition can be acquired or congenital, …

Brachial Artery Aneurysm After Arteriovenous Fistula Ligation Status Post-Kidney Transplant, Alyssa Imperatore, Justin Adibi, Rahul Sharma, Yury Bak

Rowan-Virtua Research Day

Arteriovenous fistulas (AVF) are the most common and effective method of receiving hemodialysis; However, these access techniques do not come without consequence. Aneurysmal degeneration after creation and even years after ligation of such AVF can occur. This is still considered a rare complication. A true brachial artery aneurysm has an overall incidence of 0.17% among peripheral artery aneurysms. Factors that increase incidence of this complication include trauma, age and immunosuppression. Research on this topic is becoming more prevalent, but more answers are still needed. Below is a case of brachial artery aneurysm presenting years after AVF ligation in a patient …

Case Study Of Pulmonary Embolism With Unusual Chief Complaint, Kajel Patel

Rowan-Virtua Research Day

Pulmonary embolism (PE) is a serious diagnosis that needs to be made in the Emergency department (ED). There are different categories of PE ranging from massive to non-massive/sub-segmental. Regardless of the categorization, the patient will need to be placed on anticoagulation. It is important to catch this diagnosis in the ED so further complications do no arise. Here is a case from the ED with a patient coming in with the chief complaint of acute right lower quadrant abdominal pain and was diagnosed with a pulmonary embolism.

The Impact Of Prolonged Estrogen Deficiency On Cardiac Hypertrophy Following Chronic Sympathetic Stimulation, Isabelle Krueger

Undergraduate Honors Theses

Cardiovascular disease (CVD) is the leading cause of death for both men and women in developed countries. Compared to age-matched males, premenopausal women experience lower rates of CVD but this increases after menopause. A central feature in CVD is changes in sympathetic regulation leading to pathological changes such as cardiac hypertrophy characterized by changes in cardiomyocyte size due to overcompensation of the muscle following injury. The goal of this research is to study the effect of prolonged estrogen loss on cardiac hypertrophy following chronic sympathetic stimulation. Female mice were ovariectomized at 10 weeks of age and treated with Isoproterenol to …

Relationship Between Global Cognition And Cardiovascular Risk Factors, Alexia Sebghati

Health, Human Performance and Recreation Undergraduate Honors Theses

Alzheimer’s disease (AD) is currently affecting the lives of 5.8 million Americans and is expected to double within the next 30 years. With an aging populace of baby boomers, this will place great economic strain on the U.S. creating a burden of almost $1 trillion in healthcare costs. Currently, there is no cure for AD. However, studies report that many individuals with AD experience changes in the brain up to 10-15 years before the disease’s onset. It is imperative to detect future risk of developing AD or mild cognitive impairment (MCI) before significant cognitive changes arise. Many of the risk …

Perivascular Adipose Tissue In Relation To Diet, Thermogenesis And Cardiovascular Health, Ginger Paquette, Caitlin Stieber, Ashely Soucy, Benjamin Tero, Lucy Liaw

Thinking Matters Symposium

Adipose tissue is a diverse and crucial component to vascular health due to its role in energy storage and heat production. The primary function of white adipose tissue (WAT) is energy storage while the function of mitochondria-rich brown adipose tissue (BAT) is heat production. Perivascular adipose tissue (PVAT), which surrounds blood vessels, contains both WAT and BAT adipocytes. Dietary calorie restriction is associated with increased lifespan with decreased adiposity. Increased prevalence of WAT-like PVAT, due to high-fat diets and obesity, leads to increased metabolic disfunction and cardiovascular-disease. We used a calorie-restriction model in C57BL6/J mice to test the hypothesis that …
