Heart Transplantation In A Patient With Rheumatic Heart Disease And Severe Left Atrial Calcification, Kyungsub Song, Seonhwa Lee, Yun Seok Kim May 2024

Heart Transplantation In A Patient With Rheumatic Heart Disease And Severe Left Atrial Calcification, Kyungsub Song, Seonhwa Lee, Yun Seok Kim

The Texas Heart Institute Journal

A 62-year-old woman who had undergone mitral valve replacement 24 years ago was admitted to the hospital with congestive heart failure. She needed heart transplantation for stage D heart failure. Preoperative cardiac computed tomographic scans showed a severely calcified left atrium and a large right atrium. Given that the left atrium's calcification was too severe to suture, the calcified left atrial wall was broadly resected, and the resected left atrial wall was reconstructed with a bovine pericardial patch for anastomosis with the donor's left atrial wall. The operation was completed without heavy bleeding, and the patient was discharged from the …

Clinical Outcomes For Impella Patients Associated With Hyperlipidemia: An Analysis Of The National Inpatient Sample, Tony Elias, Sonika Vatsa, Kyrillos Gamal, Taha Syed, Rafail Beshai

Rowan-Virtua Research Day

The Impella, a ventricular assist device, is crucial for managing severe heart failure and cardiogenic shock. Despite its widespread use, there's scant information on how hyperlipidemia affects Impella patients. To address this gap, we delved into the National Inpatient Sample Database from 2019 and 2020. Our aim was to scrutinize in-hospital outcomes among these patients. We identified 8233 Impella patients, among whom 1012 (12.3%) had hyperlipidemia. Those with hyperlipidemia displayed higher rates of hypertension, diabetes mellitus, and chronic kidney disease compared to their counterparts without hyperlipidemia. Shockingly, in-hospital mortality was notably elevated in the hyperlipidemia group, emphasizing its clinical significance. …

Improving Nutrition Screening Practice In The Hospitalized Heart Failure Patient Population, Amanda J. Bourgeois Jan 2024

Improving Nutrition Screening Practice In The Hospitalized Heart Failure Patient Population, Amanda J. Bourgeois

DNP Projects

Background: Heart Failure is a disease known to affect nearly 6.5 million adults in the United States. Characterized by recurrent hospitalizations, heart failure significantly contributes to morbidity, mortality, and healthcare costs in the United States and worldwide. Because malnutrition is prevalent in the heart failure population, healthcare providers must perform nutritional assessments on admission to intervene in the case of malnutrition, prevent deterioration, and improve patient prognosis. Without intervention and early identification of malnutrition, heart failure hospitalizations will remain a significant problem.

Purpose: The purpose of this study is to evaluate the effect of an evidence-based educational program for cardiac …

How Do We Define High And Low Dose Intensity Of Heart Failure Medications: A Scoping Review, Min Ji Kwak, Qian Wang, Chukwuma Onyebeke, Travis Holder, Parag Goyal, Rajender Aparasu, Abhjeet Dhoble, Holly M Holmes Sep 2023

How Do We Define High And Low Dose Intensity Of Heart Failure Medications: A Scoping Review, Min Ji Kwak, Qian Wang, Chukwuma Onyebeke, Travis Holder, Parag Goyal, Rajender Aparasu, Abhjeet Dhoble, Holly M Holmes

Journal Articles

BACKGROUND: Older adults with heart failure often experience adverse drug events with high doses of heart failure medications. Recognizing whether a patient is on a high or low dose intensity heart failure medication can be helpful for daily practice, since it could potentially guide the physician on which symptoms to look for, whether from overdosing or underdosing. However, the current guideline does not provide sufficient information about the dose intensity below the target dose. Furthermore, the definition of high or low-intensity heart failure medication is unclear, and there is no consensus.

METHODS: To close the knowledge gap, we conducted a …

Journal Articles

AIMS: To optimize guideline-directed medical therapy for heart failure, patients may require the initiation of multiple neurohormonal antagonists (NHAs) during and following hospitalization. The safety of this approach for older adults is not well established.

METHODS AND RESULTS: We conducted an observational cohort study of 207 223 Medicare beneficiaries discharged home following a hospitalization for heart failure with reduced ejection fraction (HFrEF) (2008-2015). We performed Cox proportional hazards regression to examine the association between the count of NHAs initiated within 90 days of hospital discharge (as a time-varying exposure) and all-cause mortality, all-cause rehospitalization, and fall-related adverse events over the …


Spontaneous Iliac Arteriovenous Fistula, High-Output Heart Failure, And Cardiac Arrest, J. Maxwell Piraneo, Russell Mordecai, James Espinosa, Alan Lucerna May 2023

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.

Role Of Macrophages In Regression Of Myocardial Fibrosis Following Alleviation Of Left Ventricular Pressure Overload, Lily Neff Apr 2023

Role Of Macrophages In Regression Of Myocardial Fibrosis Following Alleviation Of Left Ventricular Pressure Overload, Lily Neff

MUSC Theses and Dissertations

Antecedent conditions that affect the heart, such as aortic stenosis (AS), can develop into left ventricular pressure overload (LVPO). LVPO is associated with increased myocardial interstitial fibrosis, specifically fibrillar collagen, that leads to increased myocardial stiffness. Patients undergoing surgical aortic valve replacement (SAVR) to correct AS demonstrate significant but incomplete regression of fibrosis. Although current therapies normalize hemodynamic load, treatments that regress collagen content within the myocardium remain a critical need. To elucidate cellular mechanisms of this persistent fibrosis in LVPO, we utilized a transverse aortic constriction (TAC) and removal of the constriction (unTAC) murine model. Outputs were assessed for: …


The Evolution Of Durable, Implantable Axial-Flow Rotary Blood Pumps, P Alex Smith, Yaxin Wang, O H Frazier Mar 2023

The Evolution Of Durable, Implantable Axial-Flow Rotary Blood Pumps, P Alex Smith, Yaxin Wang, O H Frazier

The Texas Heart Institute Journal

Left ventricular assist devices (LVADs) are increasingly used to treat patients with end-stage heart failure. Implantable LVADs were initially developed in the 1960s and 1970s. Because of technological constraints, early LVADs had limited durability (eg, membrane or valve failure) and poor biocompatibility (eg, driveline infections and high rates of hemolysis caused by high shear rates). As the technology has improved over the past 50 years, contemporary rotary LVADs have become smaller, more durable, and less likely to result in infection. A better understanding of hemodynamics and end-organ perfusion also has driven research into the enhanced functionality of rotary LVADs. This …

Journal Articles

BACKGROUND: Chronic kidney disease (CKD) is characterized by increased myocardial mass despite near-normal blood pressure, suggesting the presence of a separate trigger. A potential driver is SIRPα (signal regulatory protein alpha)-a mediator impairing insulin signaling. The objective of this study is to assess the role of circulating SIRPα in CKD-induced adverse cardiac remodeling.

METHODS: SIRPα expression was evaluated in mouse models and patients with CKD. Specifically, mutant, muscle-specific, or cardiac muscle-specific SIRPα KO (knockout) mice were examined after subtotal nephrectomy. Cardiac function was assessed by echocardiography. Metabolic responses were confirmed in cultured muscle cells or cardiomyocytes.

RESULTS: We demonstrate that …
