A Case Of Device Lead Induced Severe Tricuspid Regurgitation And Right-Sided Heart Failure, Nina Shyama Appareddy, Michaela Iglesia, Ayman Khaddam, Henry Kwang, Eduardo D. Flores

Research Colloquium

Background: Interference of device leads with closure of the tricuspid leaflets can cause severe tricuspid regurgitation (TR) and right-sided heart failure, as can heart failure with reduced LV function (HfrEF), and left sided valve disease.

Case Presentation: A 78-year-old male with history of coronary artery disease s/p remote coronary bypass, ischemic cardiomyopathy with left ventricular ejection fraction 35-40%, and inducible ventricular tachycardia status post defibrillator presented with worsening dyspnea on exertion, easy fatigue, lower extremity pitting edema, anasarca, abdominal bloating and new systolic murmurs at the right upper and left lower sternal borders. An Echocardiogram demonstrated severe aortic stenosis with …

Taking The Load Off: Device Lead-Induced Severe Tricuspid Regurgitation And Right-Sided Heart Failure Treated With Transcatheter Aortic Valve Implantation (Tavi), Nina Shyama Appareddy, Michaela Iglesia, Ayman Khaddam, Henry Kwang, Eduardo Flores

Research Symposium

Background: Interference of device leads with closure of the tricuspid leaflets can cause severe tricuspid regurgitation (TR) and right-sided heart failure, as can heart failure with reduced ejection fraction (HFrEF) and left sided valve disease. We report a case treated with transcatheter aortic valve implantation (TAVI) with improved TR.

Case: A 78-year-old male with coronary artery disease status post remote myocardial infarction and coronary bypass, HFrEF with left ventricular ejection fraction 35-40%, and inducible ventricular tachycardia status post AICD placement presented with worsening dyspnea on exertion, easy fatigue, lower extremity edema, anasarca and abdominal bloating. Transthoracic echocardiography demonstrated severe aortic …

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 …

Prescribing Patterns Of Fall Risk-Increasing Drugs In Older Adults Hospitalized For Heart Failure, Esther Liu, Musarrat Nahid, Mahad Musse, Ligong Chen, Sarah N Hilmer, Andrew Zullo, Min Ji Kwak, Mark Lachs, Emily B Levitan, Monika M Safford, Parag Goyal

Journal Articles

BACKGROUND: Older adults hospitalized for heart failure (HF) are at risk for falls after discharge. One modifiable contributor to falls is fall risk-increasing drugs (FRIDs). However, the prevalence of FRIDs among older adults hospitalized for HF is unknown. We describe patterns of FRIDs use and examine predictors of a high FRID burden.

METHODS: We used the national biracial REasons for Geographic and Racial Differences in Stroke (REGARDS) study, a prospective cohort recruited from 2003-2007. We included REGARDS participants aged ≥ 65 years discharged alive after a HF hospitalization from 2003-2017. We determined FRIDs -cardiovascular (CV) and non-cardiovascular (non-CV) medications - …

Real-World Safety Of Neurohormonal Antagonist Initiation Among Older Adults Following A Heart Failure Hospitalization, Parag Goyal, Andrew R Zullo, Barbara Gladders, Chukwuma Onyebeke, Min Ji Kwak, Larry A Allen, Emily B Levitan, Monika M Safford, Lauren Gilstrap

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 …

Mixed Beri’S: High Output Heart Failure From Severe Anemia And Thiamine Deficiency, Rohan Umrani, Hiral Amin, Ashley Pinckney, Charles Yang, Daniel Tran

Rowan-Virtua Research Day

Background: Severe anemia and thiamine deficiency can independently result in high output heart failure (HOHF) through different mechanisms. Data on the threshold and timeframe at which these etiologies may precipitate HOHF is unclear.

Case: A 63-year-old male with alcohol use disorder consuming 18 drinks/week presented with progressive shortness of breath and lower extremity edema for a few months. Physical exam revealed tachycardia, anasarca, jugular venous distension, Lancisi’s sign, and a midsystolic murmur. Echocardiogram demonstrated EF of 30-35%, dilated left ventricle, and cardiac index of 4.2L/min/m2.

Decision-Making: Heart failure can independently precipitate anemia while severe alcoholism can induce myelosuppression and promote …

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

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: …

Journal Articles

IMPORTANCE: Age-related macular degeneration (AMD) is a leading cause of blindness with no treatment available for early stages. Retrospective studies have shown an association between metformin and reduced risk of AMD.

OBJECTIVE: To investigate the association between metformin use and age-related macular degeneration (AMD).

DESIGN, SETTING, AND PARTICIPANTS: The Diabetes Prevention Program Outcomes Study is a cross-sectional follow-up phase of a large multicenter randomized clinical trial, Diabetes Prevention Program (1996-2001), to investigate the association of treatment with metformin or an intensive lifestyle modification vs placebo with preventing the onset of type 2 diabetes in a population at high risk for …
