Percutaneous Closure Of Ventricular Septal Rupture After Myocardial Infarction:, Thomas A. Cook, Simone K. Schumaecker, Anjani Patibandla, Nicholas J. Valle, Matthew R. Summers

Department of Medicine Faculty Publications

BACKGROUND: Ventricular septal rupture (VSR) following acute myocardial infarction is a rare but deadly complication with mortality rates exceeding 90% when left untreated. Coronary ischaemia leads to myocardial necrosis and friability resulting in septal rupture, most commonly 3-5 days post-infarction. The sudden development of a left-to-right shunt causes volume overload in the right ventricle, pulmonary vasculature, and left atrium, precipitating biventricular failure, and cardiogenic shock. Management requires careful consideration of timing and modality of closure along with stabilization with mechanical circulatory support in severe cases.

CASE SUMMARY: A 65-year-old female presented with anterior ST-segment elevation myocardial infarction complicated by VSR …

Complicated Third Sternotomy For Left Ventricular Outflow Tract Obstruction Secondary To Mitral Valve Prosthesis Strut, Rishab Agarwal, Alleabelle Bradshaw, Michelle Carvajal, Jennifer S. Lawton

Department of Medicine Faculty Publications

Introduction: LVOT obstruction after surgical bioprosthetic MVP placement is uncommon and the influence of the MVP strut width has seldom been examined.

Case presentation: A 74-year-old female presented with palpitations, chest pain, and shortness of breath. She had MVR with 31-mm bioprosthetic valve 2 years prior. TEE confirmed LVOT obstruction secondary to a MVP strut, causing a peak gradient of 55 mmHg. The redo operation was complicated by iatrogenic Type A aortic dissection. The patient was immediately cooled for DHCA with RCP and ascending aortic replacement was performed. MVR was then performed with a prosthesis with narrower strut width. Recovery …

Dietary Intake Of Micro- And Nanoplastics: Potential Adverse Gi Effects On Microbiome, Inflammation, And Neoplasia, Michael Saadeh, Gordon Hong, Sana Rabeeah, Priyata Dutta, Edward C. Oldfield, Iv, David A. Johnson

Department of Medicine Faculty Publications

Micro- and nanoplastics (MNPs) are pervasive in food-contact environments and the human diet, positioning the gastrointestinal (GI) tract as the primary portal of entry and a plausible site of early biological effects. Human exposure is supported by detection of microplastics in stool and colon tissue, and emerging clinical studies report associations between fecal microplastic burden and GI disease states, including inflammatory bowel disease (IBD) and colorectal cancer (CRC). Preclinical studies provide mechanistic plausibility, reporting that ingested MNPs can modulate microbial ecology, alter mucus membrane integrity, increase intestinal permeability through changes in cellular tight junction biology, and induce inflammatory gene expression. …

Micro- And Nanoplastics: A Paradigm Shift In The Pathogenesis Of Inflammatory Bowel Disease, Michael Saadeh, Priyata Dutta, Gordon Hong, Edward Oldfield, David A. Johnson

Department of Medicine Faculty Publications

Micro- and nanoplastics (MNPs) are pervasive environmental contaminants with growing recognition as potential contributors to human disease. Widespread human exposure occurs primarily through ingestion of contaminated food and water, and MNPs have been detected in multiple human tissues, including the gastrointestinal tract. Experimental evidence provides a plausible biological basis for disease associations, including impairment of intestinal barrier integrity, activation of mucosal immune pathways, and alteration of gut microbial communities caused by MNP exposure. Although human data remain limited, early studies demonstrate MNP detection in stool and suggest potential correlations with inflammatory biomarkers such as fecal calprotectin. These findings, together with …

Seasonal And Geographic Patterns Of Gastroschisis In Canada: Protective Effect Of Periconceptional Sunlight Exposure, Shiliang Liu, Shin Jie Yong, Dunjin Chen, Gavin C. Hughes, Claude L. Hughes

Department of Medicine Faculty Publications

Background: Gastroschisis is a right-sided, full-thickness defect with extra-amnionic herniation of abdominal contents directly into the amniotic cavity. The causes of gastroschisis remain obscure. We hypothesized that limited periconceptional sunlight exposure might lead to insufficient vitamin D during fetal development and play a role in gastroschisis etiology.

Methods: We conducted a population-based cohort study of infants conceived in Canada between April 2006 and March 2020. We used winter months (i.e., November and December) and northern geographic latitudes as indicators of insufficient sunlight exposure, while summer months (July and August) and southern geographic latitudes were considered as reference. We examined the …

Balloon Aortic Valvuloplasty As A Bridge Therapy In Acute Valve Syndrome: A Narrative Review Of Evidence Gaps And Future Directions, Omar Saleh, Omar Jafar, Nicholas Valle, Shirish Yasa, Saleh Mostafa, Raymond L. Benza, Deepak R. Talreja, Benjamin D. Peterson, Matthew R. Summers

Department of Medicine Faculty Publications

Acute valve syndrome (AVS) represents a high-acuity, decompensated presentation of severe aortic stenosis (AS), often manifesting as acute heart failure, cardiogenic shock, or cardiac arrest. Transcatheter aortic valve replacement (TAVR) remains the only durable therapy for severe AS in patients with prohibitive surgical risk, yet AVS patients may be too unstable for standard preprocedural planning. Balloon aortic valvuloplasty (BAV) has re-emerged as a bridge strategy that can provide rapid hemodynamic stabilization and permit subsequent valve replacement. Registry analyses report lower mortality in emergent TAVR compared with BAV, but these comparisons are confounded by procedural indication and unmatched AS severity. Smaller …

All-Inside Arthroscopic Technique For Repairing Radial Meniscus Tears At The Anterior Horn-Body Junction, Brandon Omari Boyd, Robert M. Walker, Harrison A. Volaski, Ferdinand J. Chan

Department of Medicine Faculty Publications

Radial meniscus tears are a common tear pattern that, if left untreated, can ultimately lead to accelerated degenerative changes and disability. There is well-established evidence that supports meniscal preservation in patients with radial meniscus tears. Various surgical techniques are used to repair radial tears, including inside-out, outside-in, and all-inside methods. Self-retrieving all-inside devices are a safe option when repairing radial tears. However, radial tears at the junction of the anterior horn and body present a unique surgical challenge, as surgeons may have difficulty maneuvering the jaws of the self-retrieving suture device around the anterior limb of the meniscal tear. We …

Department of Medicine Faculty Publications

[Introduction] A man in his early 30s presented with a longstanding birthmark on the lift thigh that was first noticed at age 12. As a teenager, the lesion was treated with a CO2 laser at an outside institution; however, the lesion continued to slowly enlarge over the past several years. The patient reported recurrent irritation and swelling from a construction safety harness with occasional bleeding and frequent bruising. Recently, the area became inflamed, prompting an ER visit, where the patient was evaluated for cellulitis, underwent a normal ultrasound and was placed on cephalexin 500 gm twice daily for 10 days.

Microplastics, Nanoplastics, And Obesity: Current Evidence And Biological Mechanisms, Maram Albandak, Sanam Rabeeah, Ahmad Mahdi Zahidi, David A. Johnson

Department of Medicine Faculty Publications

Obesity is a rapidly growing global health concern. The pathogenesis is complex and cannot be fully explained by lifestyle factors alone. The increasing attention towards this concern has finally been directed towards environmental contributors which may influence metabolic regulation. Microplastics and nano-plastics (MNPs) are ubiquitous environmental pollutants that have recently been detected in food, drinking water, air, and human biological samples, raising concerns about their potential role in metabolic disorders, including obesity. Chronic exposure to MNPs may interfere with metabolic homeostasis through multiple biological pathways. Emerging evidence, including both experimental and animal studies, reports alterations in lipid metabolism, body weight, …

Psotka, Norman Stockbridge, James Januzzi, Javed Butler, Jennifer Cowger, Biykem Bozkurt, John Spertus

Department of Medicine Faculty Publications

Heart failure (HF) clinical trials increasingly rely on diverse endpoints beyond mortality, including hospitalizations, imaging, hemodynamic status, biomarkers, functional capacity, and patient-reported outcomes. Although statistically significant differences between treatment groups are commonly reported, interpreting whether these changes are clinically meaningful for individual patients remains challenging. This JACC: Heart Failure position statement proposes a pragmatic framework for defining clinically meaningful within-patient change across commonly used HF outcomes by integrating measurement variability, prognostic associations, and patient-anchored evidence where available. Relative and absolute risk reductions should both inform interpretation of clinical events, while imaging, hemodynamic, biomarker, and functional measures require changes exceeding measurement …
