PURPOSE: Aging contributes significantly to cardiovascular diseases and cardiac dysfunction, leading to the upregulation of matrix metalloproteinase-9 (MMP-9) in the heart and a significant decrease in hydrogen sulfide (H2 S) content, coupled with impaired cardiac diastolic function. This study explores whether supplementing exogenous hydrogen sulfide during aging ameliorates the decline in H2 S concentration in the heart, suppresses MMP-9 expression, and improves the age-associated impairment in cardiac morphology and function...

Contrast-enhanced ultrasound (CEUS) is an advanced ultrasound (US) technique utilizing ultrasound contrast agents (UCAs) to provide detailed visualization of anatomic and vascular architecture, including the depiction of microcirculation. CEUS has been well-established in echocardiography and imaging of focal hepatic lesions and recent studies have also shown the utility of CEUS in non-hepatic applications like the urinary system. The updated guidelines by the European Federation of Societies for Ultrasound in Medicine and Biology (EFSUMB) from 2018 describe the use of CEUS for non-hepatic applications...

Situs abnormalities may occur in many and most often more complex congenital cardiac malformations. These conditions are collectively referred to as heterotaxy syndromes, derived from the Greek words "heteros" meaning different and "taxos" meaning orientation or arrangement. Clinically, heterotaxy spectrum encompasses defects in the left-right laterality and arrangement of visceral organs. "Situs" is derived from Latin and is the place where something exists or originates. In human anatomy, situs can be solitus (derived from Latin, meaning "normal"), inversus, or ambiguus...

BACKGROUND: Atrial fibrillation (AF) represents the most prevalent cardiac arrhythmia globally, with a significant burden on mortality and morbidity. While rhythm control strategies, particularly electrical cardioversion (EC), have gained traction in recent years, the precise impact of sinus rhythm (SR) restoration on cardiac reverse remodeling remains a subject of debate. METHODS: In this study, 23 AF patients underwent elective EC. AF diagnosis was made via ECG by a cardiologist, and candidates for cardioversion were selected by an electrophysiologist...

Total anomalous pulmonary venous return (TAPVR) represents a group of anomalies consisting of a lack of connection between the pulmonary veins and the left atrium. All oxygenated pulmonary venous return flows directly or indirectly into the right atrium. Survival is only possible with a right-to-left atrial shunt. It remains rare, accounting for less than 1% of all congenital heart diseases. Its association with tetralogy of Fallot is much rarer and has been documented in medical literature as isolated cases...

The escalating incidence of infective endocarditis (IE) caused by aminoglycoside-resistant Enterococcus is a growing concern for clinicians. This issue is particularly pronounced in elderly patients, who face an elevated risk of renal damage during antibiotic treatment, thereby limiting available pharmacological options. Furthermore, elderly patients often present with multiple comorbidities, leading to heightened mortality rates. In this article, we present a case involving an elderly male patient who sought medical attention on two separate occasions due to inflammation of the lower extremities and lumbosacral pain...

BACKGROUND: The diagnosis of myocarditis remains challenging due to its diverse clinical manifestations. We recently demonstrated the ability of magnetocardiography (MCG) to screen for myocarditis and applied it successfully to detect myocarditis in this case study of a female-to-male (FtM) patient who had undergone sexual reassignment surgery. This case highlights two significant points: first, sex differences in myocarditis may be promoted by higher levels of testosterone, and second, the ability of MCG to diagnose myocarditis...

A 45-year-old male was diagnosed with arrhythmia during a routine health examination. Findings from different modalities, such as echocardiography and radiography, were consistent with cardiac involvement in sarcoidosis. There was no ocular involvement or superficial lymph node enlargement. A chest computed tomography scan did not reveal any pulmonary lesions or bilateral hilar lymphadenopathy. To pathologically diagnose systemic sarcoidosis, transbronchial lung cryobiopsy was performed. Results showed pathological evidence of noncaseating epithelioid granulomas...

Echocardiography is pivotal for diagnosis and monitoring of hypertrophic cardiomyopathy (HCM) and can evaluate myocardial function using myocardial work (MW) calculations. Echocardiography is often supplemented by cardiovascular magnetic resonance (CMR) imaging, which can detect myocardial fibrosis using late gadolinium enhancement (LGE). We sought to study the relationship between baseline LGE and MW at baseline and during follow-up in pediatric HCM patients. During the study period (2008-2023), 75 patients were followed up for HCM...

A 2-year-old castrated Russian Blue cat presented with inappetence, depression, and labored respirations. Radiography findings suggested left lung atelectasis; however, the ultrasonography findings did not indicate lung atelectasis. The left pulmonary artery (PA) was abnormally small on echocardiography; further, there were no other cardiac anomalies. Computed tomography revealed an abnormally small left PA and left lung. Furthermore, bronchiectasis and tree-in-bud patterns were observed in the lung lobes. Based on these findings, the cat was diagnosed with isolated left PA hypoplasia, presumed left lung hypoplasia, and feline chronic bronchial disease...
