Extracavitary Cardiac Calcific Amorphous Tumors Compressing Biventricular Outflow Tracts.

Extracavitary cardiac calcific amorphous tumors/masses are extremely rare. We present a case report of a 62-year-old man with end-stage renal disease who presented with extracavitary cardiac calcific amorphous tumors/masses compressing the biventricular outflow tracts, resulting in hemodynamic compromise and progressive limitation of activities. The patient was successfully treated with surgery, with complete resolution of symptoms and markedly improved quality of life.

Intracardiac Teratoma in a Patient With Nonseminomatous Germ Cell Tumor.

This case report describes the management of a 30-year-old male patient with a history of an advanced nonseminomatous germ cell tumor, hip fracture complicated by extensive deep vein thrombosis and pulmonary embolism, and on apixaban presenting with asymptomatic intracardiac teratoma and abdominopelvic metastases. Multidisciplinary intervention, including successful surgical excision of the intracardiac mass, highlights the importance of coordinated care and vigilant follow-up in optimizing patient outcomes and preventing life-threatening complications.

Tongue Squamous Cell Carcinoma With Cardiac Metastases.

A 60-year-old man with squamous cell carcinoma of the tongue had atypical chest pain and mild troponin elevation. No significant electrocardiogram changes or arrhythmias were noted.

Obstructive Thrombosis of Transcatheter Pulmonary Valve-in-Valve Prosthesis.

A 79-year-old woman, previously treated for congenital pulmonary valve stenosis through surgical and transcatheter procedures, presented with worsening dyspnea. This led to the identification of valve thrombosis in her bioprosthetic pulmonary valve. This report delves into the clinical importance of obstructive valve thrombosis, its diagnostic assessment, and potential therapeutic strategies.

Clinical Presentation and Percutaneous Treatment of Hemolytic Anemia Associated With Paravalvular Leak After TAVR.

Paravalvular leak (PVL) following transcatheter aortic valve replacement (TAVR) is an established complication, albeit rarely associated with hemolytic anemia. This report details 3 cases of significant hemolytic anemia attributed to TAVR-induced PVL, each with distinct clinical presentations and manifestations. These cases underscore the diverse and occasionally subtle clinical presentation of aortic PVL-associated hemolytic anemia.

Unveiling Cardiac Mysteries: The Role of Endomyocardial Biopsy in Diagnosing Heart Masses.

This case series highlights the role of endomyocardial biopsy (EMB) in diagnosing cardiac tumors instead of tumor resection. EMB provided critical diagnostic clarity and influenced therapeutic decisions, demonstrating its utility in complex cardiovascular cases while preventing unnecessary surgery. Furthermore, EMB provides vital information that can be used for a multidisciplinary approach to cardiac tumors.

Critical Acute Left Ventricular Outflow Tract Obstruction Due to Cardiac Sarcoma.

Left ventricular outflow tract (LVOT) obstruction is mostly caused by hypertrophic obstructive cardiomyopathy and subaortic stenosis. Rarely, malignancy can lead to dynamic LVOT obstruction and has only been sporadically documented. We present the first case of dynamic and/or nearly fixed LVOT obstruction caused by a cardiac myxoid spindle cell sarcoma.

TEER for SAM of the Mitral Valve and Flail Posterior Mitral Leaflet: 1-Clip Solution.

Transcatheter edge-to-edge repair (TEER) is approved for patients with symptomatic severe mitral regurgitation (MR) who are deemed inoperable or at high surgical risk with life expectancy of more than 1 year, but has also been used off-label in patients with hypertrophic obstructive cardiomyopathy (HOCM) for symptomatic relief who are not candidates for septal reduction therapy. An 83-year-old woman with decompensated heart failure was found to have HOCM with systolic anterior motion of the mitral valve and a large P2 flail segment with ruptured cords. TEER was performed resulting in mild MR and resolution of the prior left ventricular outflow tract gradient.

Transcatheter Aortic Valve Replacement in Patients With Interventricular Membranous Septal Aneurysms.

Aneurysms of the interventricular membranous septum are a rare anatomical feature that can be detected incidentally on computed tomography or echocardiography. Such aneurysms can pose challenges in the treatment of patients with aortic valve stenosis. A case series of 2 patients with membranous septal aneurysms treated successfully with current-generation balloon-expandable and self-expanding transcatheter heart valves is presented here.

Surgical-related Morphological Characteristics of Sphenoid Sinuses: A Comprehensive CT-Based Analysis.

Background: This study aims to assess the relationships between sphenoid sinus (SS) types, septation, lobulation, symmetry, septal deviation, and the variations in SS pneumatization regarding the surrounding neurovascular structures using Computed tomography (CT) images. Sexes and age groups were investigated.

Material And Methods: We retrospectively evaluated head CT-scans of 320 patients (age range 18-49 years); mean of 43.

An Acellular Platform to Drive Urinary Bladder Tissue Regeneration.

Impaired bladder compliance secondary to congenital or acquired bladder dysfunction can lead to irreversible kidney damage. This is managed with surgical augmentation utilizing intestinal tissue, which can cause stone formation, infections, and malignant transformation. Co-seeded bone marrow mesenchymal stem cell (MSC)/CD34+ hematopoietic stem cell (HSPC) scaffolds (PRS) have been successful in regenerating bladder tissue.

Response to induction chemotherapy modifies the effect of conventional prognostic factors in high-risk neuroblastoma: A report from the Children's Oncology Group.

Background: Response to induction chemotherapy has been shown to predict outcome in patients with high-risk neuroblastoma (HR-NB), with those achieving a complete response (CR) having superior outcomes.

Methods: We evaluated whether conventional prognostic factors remain prognostic in subsets of patients defined by response to induction. 1244 Patients from four COG high-risk trials were included.

A Triple Threat: A Case Report Detailing Surgical Management for Hypertrophic Cardiomyopathy, Flail Mitral Valve and Severe Pulmonary Hypertension.

Unlabelled: The combination of hypertrophic cardiomyopathy with outflow tract obstruction, severe pre-capillary and post-capillary pulmonary hypertension, and severe primary mitral regurgitation is rare and presents distinct management challenges.

Background And Clinical Significance: Pulmonary hypertension is an independent predictor of all-cause mortality in patients with hypertrophic cardiomyopathy managed medically and often precludes patients from undergoing cardiopulmonary bypass due to increased surgical morbidity and mortality. In studies specifically evaluating surgical myectomy, however, survival is favorable in patients with moderate-to-severe pulmonary hypertension.

Predictors of anterior chamber angle status at the time of neovascular glaucoma diagnosis.

Purpose: To identify clinical features which may predict the angle status of a large cohort of NVG eyes at the time of diagnosis.

Advances in moyamoya disease: pathogenesis, diagnosis, and therapeutic interventions.

Moyamoya disease (MMD) is a type of cerebrovascular disease characterized by occlusion of the distal end of the internal carotid artery and the formation of collateral blood vessels. Over the past 20 years, the landscape of research on MMD has significantly transformed. In this review, we provide insights into the pathogenesis, diagnosis, and therapeutic interventions in MMD.

Targeting CD45 by gene-edited CAR T cells for leukemia eradication and hematopoietic stem cell transplantation preconditioning.

Hematopoietic stem cell transplantation (HSCT) is widely used to treat patients with life-threatening hematologic and immune system disorders. Current nontargeted chemo-/radiotherapy conditioning regimens cause tissue injury and induce an array of immediate and delayed adverse effects, limiting the application of this life-saving treatment. The growing demand to replace canonical conditioning regimens has led to the development of alternative approaches, such as antibody-drug conjugates, naked antibodies, and CAR T cells.

Dementia and Cognitive Impairment in an Urban Multiethnic Indigenous Community from Amazonas.

Introduction: Studies about dementia in Indigenous communities are still scarce worldwide, especially in low-middle-income countries, limiting timely intervention in minority groups. Our research aimed to bridge this gap by determining the prevalence of dementia and mild cognitive impairment no dementia (CIND), and the associated factors, in a multiethnic Indigenous community in Manaus, Brazil.

Methods: A cross-sectional observational study evaluated the cognitive and functional performances of 141 Indigenous individuals (aged 50 and above).

Predicting Body Fat Percentage from Anthropometric Measurements in Asian Athletes.

Purpose: Researchers have predicted body fat percentage (BF%), as indicated by dual energy X-ray absorptiometry (DXA), from skinfold thicknesses in North American and European athletes, but not athletes from other regions. We sought to estimate an equation to predict BF% in elite Asian athletes from their skinfold thickness and girth measurements, with DXA as a reference method.

Methods: We collected data from two samples of athletes on Singaporean national teams.

Purpose: To determine whether there is an association between ACEi, ARB, or statin usage and stiffness after aRCR.

Study Design: Cohort study; Level of evidence, 3.

Clinical and Radiological Outcomes After Lateral Meniscal Allograft Transplantation Through a Medial Arthrotomy: A Minimum 4-Year Follow-up.

Background: Previous studies have demonstrated that lateral meniscal allograft transplantation (MAT) through medial arthrotomy showed less extrusion than that of the lateral arthrotomy. However, there is a paucity of literature reporting clinical and radiological outcomes after lateral MAT through the medial arthrotomy.

Hypothesis: Lateral MAT through a medial arthrotomy would show significantly improved clinical scores and minimal joint space narrowing compared with preoperative status.
