The VAD Journal
Left ventricular assist device (LVAD) outflow graft stenosis (OGS) is a rare but lethal complication. We present a case of a 79-year-old male with pertinent past medical history of an LVAD implanted as destination therapy, stage III chronic kidney disease, and hypertension. He was admitted for low-flow alarms, and the echocardiogram showed stable right ventricle function and no pericardial effusion. Invasive hemodynamic assessments demonstrated a peak-to-peak gradient of 90 mm Hg in the outflow graft between the mid and distal ends of the graft on pullback. Contrast angiography confirmed OGS. The OGS was successfully treated with a VBX-covered stent (Gore ...

A Unique Case Of Inflow Cannula Obstruction By A Tissue Membrane, Roopa A. Rao, Kashif Saleem, Bistees George, Maya Guglin
The VAD Journal
The use of a left ventricular assist device has increased and is a primary surgical treatment for heart failure. However, one major complication of left ventricular assist device support is an obstruction in the blood flow pathway. Pump thrombosis and outflow graft occlusion are some of the common causes of such obstructions. Here, we describe a unique case of HeartMate II (Abbott Laboratories) inflow cannula obstruction from a membranous structure without evidence of thrombus. The histology showed evidence of fibrous tissue and heart muscle tissue in the membrane. The patient underwent a successful device exchange with a HeartMate 3 (Abbott ...

Intra-Aortic Balloon Pump May Attenuate Adverse Hemodynamic Effects Of Negative Intrathoracic Pressure In Cardiogenic Shock, Faris Araj
The VAD Journal
High negative intrathoracic pressure (NIP), as occurs during obstructive sleep apnea or hiccups, results in adverse hemodynamic consequences, specifically a decrease in left ventricle (LV) performance. These untoward effects can potentially be catastrophic in the case of an already compromised LV in cardiogenic shock. The interplay of intra-aortic balloon pump counter pulsation during abrupt high NIP in cardiogenic shock is described.

Background and Objectives: Remdesivir is an antiviral drug used to treat coronavirus disease 2019 (COVID-19) with a relatively obscure cardiac efect profle. Previous studies have reported bradycardia associated with remdesivir, but few have examined its clinical characteristics. The objective of this study was to investigate remdesivir associated bradycardia and its associated clinical characteristics and outcomes. Methods: This is a single-institution retrospective study that investigated bradycardia in 600 patients who received remdesivir for treatment of COVID-19. A total of 375 patients were included in the study after screening for other known causes of bradycardia (atrioventricular [AV] nodal blockers). All patients were ...

Rapid Changes In Vascular Compliance Contribute To Cerebrovascular Adjustments During Vasovagal Syncope (Vvs), Aleena Sajid
Undergraduate Student Research Internships Conference
Background: The rapid reduction in arterial pressure (AP) during VVS is associated with a decline in diastolic cerebral blood velocity (CBV) and maintained systolic CBV. We tested the hypothesis that this response may represent increased cerebrovascular compliance (Ci) in the presence of rapid hypotension.
Methods: AP and CBV were recorded from 14 otherwise healthy patients (34 ± 11 years) at rest and during head-up tilt (80°, 5-28 min). Baseline, mid-tilt, and VVS were analyzed. Individual AP and CBV waveforms were input into a modified Windkessel model to calculate Ci.
Results: Upright posture resulted in a decrease in CBV (-9 ± 8 cm ...

Pulsatility Is A Predictive Marker Of Improved Cardiac Function In Patients With Liquid Matrix-Treated Left Ventricular Assist Devices, Philemon Mikail, Rinku Skaria, Marvin Slepian, Janny Garcia, Richard Smith, Zain Khalpey
The VAD Journal
Objective: Left ventricular assist devices (LVADs) are utilized as a bridge to transplant or as destination therapy for patients with end-stage heart failure. Although cardiac offloading from these devices rarely leads to complete remodeling and functional recovery, the use of mesenchymal cells to modulate heart failure has been explored in recent years due to its intrinsic regenerative properties. Current methods of evaluating cardiac function have too much variability, difficulty of access, or require too frequent follow up to create universal weaning protocols. We hypothesized that the administration of amniotic allograft liquid matrix (LM) containing amnion-derived mesenchymal stem cells (aMSCs) in ...

Abstract
According to the CDC (2020), heart failure occurs when the heart cannot pump enough blood and oxygen to support other organs in your body. Heart failure is an epidemic disease affecting 1-2% of the population worldwide (Schwinger, 2020). It is one of the leading causes of morbidity and mortality worldwide with an estimated 6.5 million adults with heart failure in the United States (Lo et al., 2021). Medical advances ...

Pathophysiology of Aortic Stenosis
Proper evaluation of co-morbidities is imperative for patient safety and successful outcomes for patients undergoing anesthesia. Aortic stenosis (AS) is one of the most complex diseases encountered in anesthesia, affecting five percent of older adults and ten percent of the 80-89-year-old-cohort (Joseph et al., 2017). The pathophysiological development of AS is the end result of an inflammatory process caused by endothelial damage from mechanical stress, accumulation ...

Fondaparinux As An Alternative Anticoagulant Treatment In Patients With Left Ventricular Assist Devices And Recurrent Gastrointestinal Bleeding: Case Series, Daniela Piani, Andrea Lechiancole, Massimo Maiani, Igor Vendramin, Sandro Sponga, Elisabetta Auci, Ugolino Livi
The VAD Journal
Gastrointestinal bleeding (GIB) can occur in patients after left ventricular assist device (LVAD) implantation. In cases of recurrent GIB, the management of anticoagulation treatment represents a challenging situation in which the risk of bleeding recurrence and the need for long-term anticoagulation must be balanced. This case series describes the successful management of anticoagulation in three patients with recurrent GIB using fondaparinux.
To our knowledge, these are the first reported cases of recurrent GIB in which a single dose of subcutaneous fondaparinux was used instead of oral anticoagulation. None of the patients presented with signs of pump thrombosis or arterial embolism ...

Diaphragmatic Adjacencies: Pulmonary Embolism Presenting As Abdominal Pain, Joseph Piraneo, Christopher Schwartz, Russell Mordecai
Stratford Campus Research Day
Pulmonary embolism is a common yet potentially life-threatening diagnosis that should not be missed in the Emergency Department. Common presenting symptoms include dyspnea, pleuritic chest pain, cough, hemoptysis, syncope or pre-syncope. Less often, however, presenting symptoms can include abdominal pain. A clinician should recognize that pain adjacent to the diaphragm (including the lower chest and upper abdomen), can be secondary to underlying pathology either above or below the diaphragm. Here we describe an unusual case of pleuritic, post-prandial, right upper quadrant abdominal pain that was a result of pulmonary embolism.

Stratford Campus Research Day
Schizophrenia (SZ) is one of the most severe forms of mental illness, yet mechanisms remain unclear. A widely established brain finding in SZ is hippocampal atrophy, and a coherent explanation similarly is lacking. Epidemiological evidence suggests increased cerebrovascular and cardiovascular complications in SZ independent of lifestyle and medication, pointing to disease-specific pathology. Endothelial cell contributions to blood-brain barrier (BBB) compromise may influence neurovascular unit and peripheral vascular function, and we hypothesize that downstream functional and structural abnormalities may be explained by impaired BBB.

Neuroanatomical Distribution Of Neurons Within The Hypothalamic Paraventricular Nucleus That Project To The Brainstem Rostral Ventrolateral Medulla, Nicolas Fuller
Undergraduate Honors Theses
The sympathetic nervous system is important in maintaining cardiovascular homeostasis. Elevated cardiovascular-related sympathetic activity can lead to neurogenic hypertension and a host of other serious cardiac-related abnormalities. The paraventricular nucleus (PVN) of the hypothalamus plays an important role in sympathetic cardiovascular regulation. Neurons from the PVN project to the rostral ventrolateral medulla (RVLM), which is the main brain stem sympathetic cardiovascular control center. While RVLM-projecting PVN neurons have been well characterized, the topographical organization within the PVN subnuclei is still not fully known. This neuroanatomical study aimed to map the topographical distribution of RVLM-projecting PVN neurons. Four different carboxylate FluoSphereTM ...

Effective Therapies And Nursing Approaches: Improving Cognition In Older Adult Stroke Patients, Selyna Baltazar
Nursing | Senior Theses
Background
Ischemic stroke occurs in thousands of older adults throughout the year. Due to the lack of oxygen entering the brain, many patients experience a decline in cognitive function due to ischemic stroke. Cognition is the ability to understand, learn, and remember information which is needed for completing daily tasks. Modern technology has allowed for patients to survive ischemic strokes but has yet to provide proper screening tools and methods for stroke-related cognitive impairment.
Objective
To investigate the best practices for identifying, treating, and caring for patients with a cognitive injury related to a stroke. A review of the research ...

Journal of Patient-Centered Research and Reviews
Purpose: Electrocardiography (ECG)-derived machine learning models can predict echocardiography (echo)-derived indices of systolic or diastolic function. However, systolic and diastolic dysfunction frequently coexists, which necessitates an integrated assessment for optimal risk-stratification. We explored an ECG-derived model that emulates an echo-derived model that combines multiple parameters for identifying patient phenogroups at risk for major adverse cardiac events (MACE).
Methods: In this substudy of a prospective, multicenter study, patients from 3 institutions (n = 727) formed an internal cohort, and the fourth institution was reserved as an external test set (n = 518). A previously validated patient similarity analysis model was used ...
