Department of Medicine Faculty Publications

Background

Retrograde valve crossing during valve-in-valve transcatheter aortic valve replacement (ViV TAVR) may fail despite modern delivery systems.

Case Summary

A 67-year-old man with a degenerated 27-mm Magna Ease bioprosthesis and unfavorable aortic geometry (kinked ascending aorta at a prior surgical graft site) underwent ViV TAVR, where retrograde valve crossing failed despite multiple stiff guidewires and snare traction alone. Successful delivery of a 29-mm Evolut FX+ was ultimately achieved by combining gooseneck-snare traction for coaxial realignment with a partially inflated Tyshak buddy balloon acting as a mechanical ramp across the surgical valve frame.

Discussion

This case demonstrates a structured, stepwise …

Incidental Cardiac Metastasis In Breast Carcinoma, Yaomin Chen, Haibo Wang, Zhiyan Fu, Ellen Elizabeth Connor

School of Medicine Faculty Publications

Background and Clinical Significance: Metastatic breast cancer is a major global health burden, with common metastatic sites including the bones, lungs, liver, and brain. Cardiac metastasis is rare and often clinically silent, leading to underdiagnosis. Recognizing cardiac involvement, even when asymptomatic, is important for understanding the full extent of disease and ensuring optimal patient care. Case Presentation: We report the case of a woman with advanced breast carcinoma who showed no clinical or imaging evidence of cardiac involvement throughout the course of her illness. Following her death from progressive metastatic disease, an autopsy revealed metastatic carcinoma infiltrating the myocardium and …

Transient Neuromonitoring Changes And Delayed Vertebrobasilar Infarction Following Anterior Cervical Discectomy And Fusion: Illustrative Case, Jacob M. Chaisson, Jack A. Leoni, Ellery A. Hayden, Gabriel C. Tender, Amit K. Bhandutia

School of Medicine Faculty Publications

BACKGROUND: Anterior cervical discectomy and fusion (ACDF) is a common spinal procedure with a well-established safety profile. While direct vertebral artery injury is rare and typically recognized intraoperatively, delayed posterior circulation stroke is an even less common but major complication. In patients with risk factors for vascular disease, vascular stress from surgical manipulation may predispose them to thromboembolic events that are not immediately apparent. Transient intraoperative neuromonitoring (IONM) changes may represent early, underrecognized indicators of such vascular compromise. OBSERVATIONS: The authors present the case of a 61-year-old male who underwent elective three-level ACDF for degenerative cervical myelopathy. During cage placement, …

Florida Journal of Emergency Medicine (FJEM)

The Fourth (4th) Universal Definition of Myocardial Infarction (UDMI) provides a standardized framework to enhance diagnostic accuracy and clinical decision-making. However, challenges can arise due to the use of subjective clinical assessment in diagnostic criteria or in the presence of impaired renal clearance. This study modifies the 4th UDMI by requiring objective ischemic evidence to improve consistency in myocardial infarction (MI) classification and applies it across diverse patient populations.

In this retrospective study, patients who presented to the emergency department (ED) with 99th percentile high sensitivity cardiac troponin (hs-cTn) values were classified using the modified 4th UDMI into the categories …

When Clotting And Bleeding Collide: A Case Of Bilateral Pe And Concurrent Upper Gi Hemorrhage, Tabitha D. Baca, David Rayburn, Daniel Castro, Jessica Aird

Florida Journal of Emergency Medicine (FJEM)

Introduction

Concurrent episodes of pulmonary emboli and gastrointestinal bleeding in one patient are not commonly seen. When a patient presents with both, it presents a challenge to manage as they are opposite ends of the same disease spectrum associated with the coagulation system.

Case Report

We present the case of a 65-year-old male who presented to our hospital via EMS with unknown prior history after a witnessed cardiac arrest, who on evaluation also had a concurrent bilateral pulmonary emboli with right heart strain.

Why should an emergency physician be aware of this?

While there is extensive research on the management …

Venous thromboembolism (VTE) is a leading cause of morbidity and mortality, with risk heightened in premenopausal women with obesity or use estrogen-based oral contraceptives. When both risk factors are present, the thrombosis risk increases substantially. Protein S (PS), an essential anticoagulant cofactor, is downregulated by both estrogen and obesity, but the molecular basis for this suppression remains poorly defined. We investigated the effect of estrogen and obesity on PS expression using plasma samples from 157 women stratified by BMI and contraceptive use, alongside 40 mice categorized as lean or obese with or without estrogen pellet treatment. The levels of PS …

Development of a Longitudinal, Small-Group POCUS Curriculum for Internal Medicine Residents

Introduction

Point-of-Care Ultrasound (POCUS) is integral for clinicians to enhance their diagnostic and procedural skills. Unlike Emergency Medicine or Anesthesia training programs, Internal Medicine programs often lack a structured and standardized curriculum. We thus developed a longitudinal and multi-pronged POCUS curriculum aimed at building trainee competency when utilizing ultrasound for diagnostic and procedural work-up.

Methods

The curriculum encompasses the following: basics of ultrasound, ultrasound-guided procedures, thoracic ultrasound/Bed Lung Ultrasound in Emergency (BLUE), and cardiac ultrasound/Focus-Assessed Transthoracic Echocardiography (FATE). These modules were integrated into the residents’ clinic blocks. We utilized …

Yaddanapudi, M. Chadi Alraies, Said Ashraf, Jeffery Van Hook, Yegeny Brailovsky

Department of Medicine Faculty Papers

BACKGROUND: CHA2DS2-VASc score in cardiac amyloidosis (CA) with atrial fibrillation (AF) is believed to underestimate ischemic stroke risk, necessitating a better predictive model.

METHODS: Data were obtained from the National Readmission Database (NRD). Outcomes between CA-AF and no-CA-AF were compared using multivariate regression analysis to calculate adjusted odds ratios (aORs). AutoScore, an interpretable machine learning framework, was used to develop a stroke risk prediction model, and its predictive accuracy was evaluated with an area under the curve (AUC) using the receiver operating characteristic analysis.

RESULTS: A total of 11,860,804 (CA-AF 22,687 (0.19%) and no-CA-AF 11,838,117) patients were identified from 2015 …


Methemoglobinemia-Induced Cardiac Dysfunction In A Pediatric Patient, Brian Drury, Chelsea Boyd, Kelsey Van Housen, Siraj Amanullah Oct 2025

Methemoglobinemia-Induced Cardiac Dysfunction In A Pediatric Patient, Brian Drury, Chelsea Boyd, Kelsey Van Housen, Siraj Amanullah

Student Papers, Posters & Projects

Methemoglobinemia is a rare congenital or acquired cause of functional anemia resulting from oxidation of hemoglobin. Prompt recognition and treatment are critical to prevent tissue hypoxia and end-organ injury. While other complications are well described, cardiac dysfunction is rarely reported—especially in children. We present what, to our knowledge, is the first known case of methemoglobinemia-induced transient cardiac dysfunction—or “myocardial stunning— in a pediatric patient. This case underscores the importance of maintaining a high index of suspicion and assessing cardiac involvement in such patients. Early intervention can lead to full recovery and prevent long-term sequelae, even in the presence of multiorgan …

Journal of the Saudi Heart Association

Streptococcus Agalactiae endocarditis is a rare clinical entity in newborns with a normal structured heart. It is generally characterized by acute onset, the presence of large vegetations, rapid valvular destruction and frequent complications, particularly embolization. Mortality is high with medical therapy alone. We are reporting a rare case of infective endocarditis (IE) with mitral valve vegetation in a 9-day old healthy newborn following Streptococcus Agalactiae sepsis, complicated by meningitis and micro-abscesses. Mitral valve (MV) vegetation was removed surgically; the patient received intravenous antibiotics for six weeks. Transthoracic echocardiography after surgery showed severe MV regurgitation and severe pulmonary hypertension which was …
