Urine high-sensitive troponin I in children cannot offer an applicable alternative to serum.

Introduction: In children, congenital heart defects represent the primary cause of increased serum troponin I. The elimination process of cardiac troponin I from the bloodstream and the factors influencing this process remain unknown. The objective of this study was to explore the role of troponin I as an indicator of cardiac damage in children both in serum and urine, a concept previously investigated in adults.

Development and validation of the project manager skills scale (PMSS): An empirical approach.

This paper presents the development and validation of the Project Manager Skills Scale (PMSS), a novel instrument designed to quantify and evaluate the critical skills of project managers. The PMSS is anchored in a comprehensive literature review and expert feedback and identifies five key dimensions of project manager skills: Technical Skills, Managerial Competences, Communication Skills, Management Style-Leadership, and Technological and Methodological Competences. The discovery of an additional fifth dimension in this study underscores the multidimensional nature of project manager skills and deviates from the initial four-cluster expectation outlined in the project management literature.

Starting Pediatric VAD Program: Transforming Challenges into Opportunities; A Case Series of a Single Center.

Background: The prevalence of heart failure is constantly increasing in both children and adults. End-stage heart failure in children unresponsive to medical therapy has limited treatment options. Surgical options include heart transplantation or implantation of durable ventricular assist devices (VADs).

Right ventricular dissection after arterial switch operation.

Herein we present the right ventricular dissection and describe its successful management after arterial switch operation in a full-term male neonate. There are no evidence-based recommendations for the management of this rare complication. Our management included veno-arterial extracorporeal membrane oxygenation placement and delayed surgical evacuation of the dissecting haematoma with beneficial outcomes.

Urine High-Sensitive Troponin T-Novel Biomarker of Myocardial Damage in Children.

Background: The use of high-sensitive cardiac troponin T (hsTnT) in urine as a marker of cardiac damage in children has not yet been reported. Elimination of cardiac troponins is dependent on renal function; persistently increased serum hsTnT concentrations were observed among individuals with impaired renal function. The aim of this study was to investigate serum and urine hsTnT levels and its correlation in infants and children younger than 24 months of age after cardiac surgery.

Veno-Arterial Extracorporeal Membrane Oxygenation as a Bridge to Heart Transplant-Change of Paradigm.

Despite advances in medical therapy and mechanical circulatory support (MCS), heart transplant (HT) remains the gold standard therapy for end-stage heart failure. Patients in cardiogenic shock require prompt intervention to reverse hypoperfusion and end-organ damage. When medical therapy becomes insufficient, MCS should be considered.

Cryopreserved human heart valve allografts: a ten-year single centre experience.

This study provides an overview of tissue banking activities at the Croatian Cardiovascular Tissue Bank (CTB) during past ten years and presents the outcomes of cryopreserved heart valve allografts (CHAs) use in different patient groups. From June 2011 until December 2021, 75 heart donations were referred to CTB: 41 recipient of heart transplant (RHT), 32 donors after brain death (DBD) and 2 donors after circulatory death (DCD) donations. Processing resulted in 103 valves of which 65 met quality requirements for clinical use.

Extracorporeal Membrane Oxygenation After Glenn Procedure in a Child With Influenza B Pneumonia.

A five-month-old male with a hypoplastic left heart syndrome developed severe respiratory insufficiency due to influenza type B viral pneumonia following bidirectional Glenn. He was treated with extracorporeal membrane oxygenation and successfully weaned without neurological consequences.

Epigenome alterations in aortic valve stenosis and its related left ventricular hypertrophy.

Aortic valve stenosis is the most common cardiac valve disease, and with current trends in the population demographics, its prevalence is likely to rise, thus posing a major health and economic burden facing the worldwide societies. Over the past decade, it has become more than clear that our traditional genetic views do not sufficiently explain the well-known link between AS, proatherogenic risk factors, flow-induced mechanical forces, and disease-prone environmental influences. Recent breakthroughs in the field of epigenetics offer us a new perspective on gene regulation, which has broadened our perspective on etiology of aortic stenosis and other aortic valve diseases.

The impact of a minimally invasive approach on reoperative aortic valve replacement.

Background And Aim Of The Study: The advantages of minimally invasive aortic valve replacement (AVR) are well documented, but whether the benefits extend to subsequent reoperative aortic valve surgery and beyond is unknown. The study aim was to compare in-hospital outcomes and long-term survival following reoperative AVR between patients who had previous undergone either minimally invasive AVR (mini-AVR) or full sternotomy AVR (sAVR).

Methods: All reoperative, isolated AVRs performed between July 1997 and September 2013 at the authors' institution, with or without non-complex aortic surgery, were identified.

Changes in IgG and total plasma protein glycomes in acute systemic inflammation.

Recovery after cardiac surgery is a complex process that has to compensate for both individual variability and extensive tissue damage in the context of systemic inflammation. Protein glycosylation is essential in many steps of the inflammatory cascade, but due to technological limitations the role of individual variation in glycosylation in systemic inflammation has not been addressed until now. We analysed composition of the total plasma and IgG N-glycomes in 107 patients undergoing cardiac surgery.

Cardiac myxoma the great imitators: comprehensive histopathological and molecular approach.

Cardiac myxomas are rare benign and slowly proliferating neoplasms of uncertain histogenesis with heterogeneous histomorphology and variable and sometimes clinically quite malignant pathological manifestations. Majority of cardiac myxoma occur sporadically while a relatively small proportion of diagnosed cases develop as a part of Carney complex syndrome with established familial pattern of inheritance. Although histologically indistinguishable these two forms of cardiac myxoma exhibit distinct cytogenetic make-up and apparent pathological differences important for their clinical presentation and prognosis.

Detecting volume responders prior to implantation of a cardiac resynchronization therapy device via minithoracotomy: the septal flash as a predictor of immediate left ventricular reverse remodeling.

Background: Although cardiac resynchronization therapy (CRT) is well established as an adjunctive heart failure treatment, a 30% rate of nonresponders poses a challenge to improve the detection of potential responders prior to device implantation. A previously proposed mechanism-based approach to patient selection suggests in part that the septal flash is a sign of intraventricular dyssynchrony, which is predictive of CRT responsiveness.

Methods: In this pilot study, data from 5 consecutive patients (2 women and 3 men; mean + or - SD age, 62 + or - 9 years) referred for CRT device implantation via a minithoracotomy were analyzed.

In-hospital outcome of 212 consecutive patients with off-pump coronary artery bypass at Zagreb University Hospital Center.

Aim: To determine the in-hospital outcome of patients undergoing off-pump coronary artery bypass grafting.

Methods: The study included 212 consecutive patients (147 men and 65 women) undergoing off-pump coronary artery bypass grafting between March 2000 and March 2002. Mean +/- SD age of the patients was 60 +/- 8 years.
