Complete Atrioventricular Block Revealing Late-Onset Cardiac Fabry Disease: Diagnostic Role Of Native T1 Mapping, Nouhaila Bentama, Lamyae Bakamel, Jalal Tagueniti, Fatiha Ait Yahya, Brahim Meftout

Journal of the Saudi Heart Association

A 63-year-old man presented with symptomatic complete atrioventricular block requiring urgent pacemaker implantation. Evaluation revealed non-obstructive left ventricular hypertrophy with normal coronary arteries. Cardiac magnetic resonance showed diffusely reduced native T1 values and inferolateral late gadolinium enhancement, suggesting Fabry cardiomyopathy; amyloidosis was excluded by bone scintigraphy. Diagnosis was confirmed by markedly reduced alpha-galactosidase A activity, elevated lyso-Gb3, and a pathogenic hemizygous GLA variant (p.Asn215Ser). Enzyme replacement therapy with agalsidase beta was initiated, with early stabilization of myocardial deformation and septal thickness. This case highlights native T1 mapping as a key diagnostic biomarker in unexplained left ventricular hypertrophy.

Modified Frozen Elephant Trunk Repair For Aortic Coarctation With Segmental Post-Stenotic Aneurysms, Pham Quoc Dat, Ma Nguyen Thai Hoang, Dang Van Phuc, Ta Dinh Do, Ngo Phi Long

Journal of the Saudi Heart Association

Aortic coarctation can be complicated by descending thoracic aortic aneurysms in adults. A 31-year-old man presented with exertional chest pain radiating to the back. Preoperative evaluation showed a 27-mmHg arm-leg systolic pressure gradient, echocardiographic coarctation with a 10-mm narrowest diameter and 25-mmHg gradient, and computed tomography showing two segmental post-stenotic aneurysms, the largest measuring 62 mm. He underwent one-stage modified frozen elephant trunk repair using a Medtronic thoracic stent graft sutured to a surgical graft. The postoperative gradient decreased to 5 mmHg, with stable 9-month follow-up.

Hubungan Kadar Fibroblast Growth Factor-23 Dalam Serum Dengan Hipertrofi Ventrikel Kiri Dan Fraksi Ejeksi Ventrikel Kiri Pada Pasien Hemodialisis Di Rumah Sakit Cipto Mangunkusumo, Ester Morina Silalahi Ester, Maruhum Bonar Marbun, Eka Ginanjar, Hamzah Shatri

Jurnal Penyakit Dalam Indonesia

Introduction. Fibroblast growth factor-23 (FGF-23) is a marker that indicates the process of bone mineral disorders in chronic kidney disease dialysis. An elevated FGF-23 causes a remodeling process that contributes to the development of left ventricle hypertrophy (LVH) and the still controversial direct decline of left ventricle ejection fraction (LVEF) among hemodialysis patients. This study aimed to seek out the connection between FGF-23 levels in serum with left ventricle hypertrophy and left ventricle ejection fraction among regular hemodialysis patients.

Methods. A cross-sectional study was conducted to 111 regular hemodialysis patients for twice a week in Cipto Mangunkusumo Hospital …

Reversible Microvascular Ischemia With St-Segment Elevation: An Underrecognized Manifestation Of Antibody-Mediated Rejection In Cardiac Allograft Recipients, Jonathan Ahn, Justin Daneshrad, Liset Stoletniy, Dmitry Abramov

The VAD Journal

Electrocardiographic manifestations of cardiac allograft rejection are often subtle, and stress-induced ST-segment elevation associated with antibody-mediated rejection (AMR) is rarely reported. We describe a 34-year-old heart transplant recipient with progressive exertional angina, nonobstructive coronary disease on angiography, and exercise-induced ST-segment elevation in lead augmented vector right, high-lateral leads I, and augmented voltage left, along with diffuse ST-segment depressions, hypotension, and transient ventricular tachycardia. Concurrent emergence of complement-binding donor-specific antibodies with high mean fluorescence intensity raised concern for AMR, prompting treatment with corticosteroids, plasma exchange, and intravenous immunoglobulin despite the absence of biopsy confirmation. After therapy, symptoms, exercise-induced ischemic electrocardiographic abnormalities, …

Journal of the Saudi Heart Association

Background: Cardiovascular, kidney, metabolic, and liver diseases are closely interconnected and frequently coexist. While the cardiovascular–kidney–metabolic (CKM) framework provides a unified model, increasing evidence supports a central role for hepatic disease, particularly metabolic dysfunction–associated steatotic liver disease (MASLD), in this continuum. The Saudi Heart Association (SHA) therefore aimed to introduce the cardiovascular–kidney–liver–metabolic (CKLM) syndrome as an expanded framework and provide expert guidance on its pathophysiology, staging, screening, and management, with relevance to the Saudi population.

Methods: A multidisciplinary expert panel convened under the auspices of the SHA conducted a comprehensive, non-systematic literature review and developed consensus-based recommendations through iterative discussion …

Simulating Pacemakers And Heartbeat Recovery Through Mathematical Modeling, Thomas Estrada, Jayla Edwards

Discovery Day - Daytona Beach

Title: Simulating Pacemakers and Heartbeat Recovery Through Mathematical Modeling   This study utilizes the Fitzhugh-Nagumo model to simulate cardiac electrical activity and the regulatory role of pacemakers through ordinary differential equations (ODEs). By defining the rate of change for membrane voltage, 𝑑𝑣/dt, and a recovery variable, 𝑑𝑤/dt, the model captures the heart's excitability and resting states. Central to the analysis is the stimulus current parameter, which represents the "kick" provided by a pacemaker to correct flatline conditions or weak heartbeats. Using Euler’s method for numerical integration, the research compares unstable cardiac rhythms against corrected periodic oscillations. Additionally, the project implements vector …

A Case Report Of Myocardial Infarction Complicated With Blood Pressure Fluctuations Caused By Pheochromocytoma, Huiping Li, Wei Yang, Yu Feng, You Zhang, Gan-Xin Yan, Chuanyu Gao

Department of Medicine Faculty Papers

Pheochromocytoma typically presents with sustained or paroxysmal hypertension, but initial manifestation as acute non-ST-segment elevation myocardial infarction (NSTEMI) is rare. Peri-procedural hemodynamic fluctuations are often dramatic, making diagnosis and management challenging. We report a 51-year-old male admitted with chest tightness for 17 days. Elevated troponin and coronary angiography showing multivessel disease with total occlusion of the mid-left anterior descending artery (LAD) led to a preliminary diagnosis of NSTEMI. During percutaneous coronary intervention, blood pressure surged to 240/130 mmHg; intravenous nitroprusside caused an instantaneous drop to 95/55 mmHg, with rapid rebound to >200 mmHg upon withdrawal, showing no clear temporal relationship …

Division of Cardiology Faculty Papers

Background: Heart failure (HF) represents the final common pathway of diverse cardiovascular disorders, including coronary artery disease, primary myocardial pathology, and abnormalities of cardiac conduction. These conditions arise from an interplay of genetic, environmental, and psychosocial influences, making it essential to understand these determinants to improve risk prediction and prevention. Multiple biological pathways of inflammation, fibrosis, coagulation, oxidative stress, lipid dysregulation, endothelial dysfunction, and metabolic disturbances are shaped by inherited susceptibility and modifiable exposures. Together, these mechanisms drive HF development and progression, though their relative contributions vary across populations. Methods: PubMed and Google Scholar were searched for clinical, biomedical, and …

High-Flow Nasal Cannula Oxygen Therapy Versus Standard Oxygen Therapy On Perioperative Outcomes In Patients Undergoing Transcatheter Aortic Valve Replacement, Kirsten B. Whiteside, Jacqueline M. Case

Graduate Theses, Dissertations, and Capstones

Abstract 

Background and Purpose: Transcatheter aortic valve replacement (TAVR) is increasingly performed under monitored anesthesia care (MAC) to facilitate faster recovery and reduce complications associated with general anesthesia. Standard oxygen therapy (SOT) may be insufficient in maintaining adequate oxygenation in this high-risk population. High-flow nasal cannula (HFNC) therapy has emerged as a potential alternative. This literature review evaluates the effects of HFNC compared with SOT on perioperative outcomes in patients undergoing TAVR under MAC. 

Methods: A comprehensive review of the literature was conducted to identify studies evaluating HFNC versus SOT during TAVR procedures performed under MAC. Six studies met inclusion …
