Article Abstract
In this case report, a 33-year-old male with a history of smoking presented with recurrent palpitations and chest discomfort. Holter monitoring revealed atrial flutter, and imaging showed a giant left atrial appendage aneurysm. Due to the risk of arrhythmias and thromboembolic events, surgical resection was performed successfully. This case underscores the importance of considering uncommon structural cardiac abnormalities in the evaluation of arrhythmia symptoms in young patients.
Undifferentiated pleomorphic sarcoma, an exceedingly rare and aggressive primary cardiac tumor arising from mesenchymal stem cells, is associated with poor prognosis and high mortality despite adequate treatment. A 52-year-old female presented with a 2-month history of angina and dyspnea on exertion. Her clinical history included severe acute respiratory syndrome coronavirus 2 myocarditis and iron deficiency anemia.
Heterotaxy syndrome, a condition in which the internal organs are abnormally arranged in the thorax or abdomen, is generally diagnosed early in life, often during the neonatal period. We present the case of a 42-year-old male who was incidentally diagnosed with polysplenia syndrome and subsequently diagnosed with heterotaxy syndrome. Upon further investigation, he was determined to have a sinus venosus type atrial septal defect.
Purpose: Intermittent hypoxia (IH), a defining feature of obstructive sleep apnea (OSA), is associated with heart damage and linked to transient receptor potential canonical channel 5 (TRPC5). Nonetheless, the function of TRPC5 in OSA-induced cardiac injury remains uncertain. For this research, we aimed to explore the role and potential mechanism of TRPC5 in cardiomyocyte injury induced by intermittent hypoxia.
Objective: The present study aimed to investigate the correlation between lipoprotein(a) (Lp-a) and coronary artery disease (CAD) complicated by type I cardiorenal syndrome (CRS).
Methods: We conducted a retrospective analysis of patients diagnosed with CAD admitted to the Department of Cardiovascular Medicine at Shaoxing Central Hospital from January 2021 to December 2022, with chief complaints of "chest distress and dyspnea." Patient demographic data, biochemical indicators (including blood lipid levels and serum creatinine), cardiac function markers (such as pro-brain natriuretic peptide, pro-BNP), echocardiography, and coronary angiography results were collected.
Introduction: Automatic segmentation of the left atrium (LA) constitutes a crucial pre-processing step in evaluating heart structure and function during clinical interventions, such as image-guided radiofrequency ablation of atrial fibrillation. Despite prior research on LA segmentation, the low contrast in medical images exacerbates the challenge of distinguishing various tissues, rendering accurate boundary delineation of the target area formidable. Moreover, class imbalance due to the small target size further complicates segmentation.
