Objective: To evaluate the possible beneficial echocardiographic, functional and quality of life improving effects of passive containment surgery using the CorCap Cardiac Support Device in heart failure patients with dilated cardiomyopathy.

Design: Eight patients with dilated cardiomyopathy subjected to cardiac surgery received the Cardiac Support Device. Patients with ischemic cardiomyopathy (n = 4) underwent coronary artery bypass surgery receiving one to three bypass grafts. In the idiopathic cardiomyopathy group (n = 4) mitral valve plasty was performed in two patients while two patients received the Cardiac Support Device only.

Results: All patients survived the surgery and were discharged to home. There was a gradual, sustained improvement in cardiac dimensions (left ventricular end-diastolic diameter, left ventricular end-systolic diameter) and functional improvement (ejection fraction, 6-min walk, NYHA functional class) as well as quality of life. These beneficial effects developed more rapidly and more extensively in the idiopathic cardiomyopathy group.

Conclusion: Addition of the Cardiac Support Device to conventional cardiac surgery, or applied alone, is safe and simple. The device seems to reverse ventricular dilatation and improve functional capacity and well-being of heart failure patients with dilated cardiomyopathy. Further studies will delineate what patient population will best benefit from passive containment surgery using the CorCap Cardiac Support Device.

Purpose: The primary challenge in infant care is developing a comprehensive, rapid, and reliable assessment tool that is minimally dependent on subjective evaluations and applicable in various inpatient settings. This study aims to develop and assess the structural validity of the Infant Nursing Assessment Scale (INA), enabling a comprehensive evaluation of hospitalized newborns and infants.

Design And Methods: A development and validation study based on cross-sectional design was undertaken.

Background: Most cancer survivors have multiple cardiovascular risk factors, increasing their risk of poor cardiovascular and cancer outcomes. The Automated Heart-Health Assessment (AH-HA) tool is a novel electronic health record clinical decision support tool based on the American Heart Association's Life's Simple 7 cardiovascular health (CVH) metrics to promote CVH assessment and discussion in outpatient oncology. Before proceeding to future implementation trials, it is critical to establish the acceptability of the tool among providers and survivors.

Purpose: To systematically evaluate the efficacy and safety of creatine phosphate sodium in the treatment of viral myocarditis, and to provide guidance for its clinical treatment.

Methods: We conducted a search of The Cochrane Library, PubMed, EMbase, and Web of Science databases to retrieve randomized controlled trials (RCTs) on the use of creatine phosphate sodium (CPS) in the treatment of viral myocarditis. The search was conducted up to April 2024.

Objectives: This retrospective study aimed to investigate the feasibility of surgical closure of ventricular septal defect in children with trisomy 18 by assessing perioperative events and long-term survival.

Methods: From April 2008 to March 2024, 41 consecutive patients were referred to us for ventricular septal defect surgery. The defect was closed in 35 patients at the end (median age, 16 months; median body weight, 5.

Background And Aims: Chemotherapy with alternating cycles of vincristine-doxorubicin-cyclophosphamide and ifosfamide-etoposide, along with primary tumor treatment with surgery or radiotherapy or both, constitute the usual treatment of Ewing sarcoma. The AEWS0031 study demonstrated survival benefits after interval-compressed chemotherapy without significant toxicity. The aim of this study was to assess the tolerability of dose-intensified chemotherapy in developing countries like India.
