The Pulse Index Contour Continuous Cardiac Output (PICCO) module provides advanced and continuous monitoring of cardiac output through the use of arterial pulse contour analysis and transpulmonary thermodilution. The objective of this study was to compare the early postoperative outcomes of patients who were monitored using the conventional method and the pulse contour analysis method. A prospective observational study was conducted involving 45 patients who underwent cardiac surgery between 2020 and 2022.

Objectives: We aim to evaluate our initial experience with the HeartMate 3 (HM3) device (Abbott, USA) for palliating pediatric patients with end-stage heart failure (ESHF).

Methods: We conducted a retrospective review of clinical data from pediatric patients (aged 7-18 years) who underwent HM3 implantation for ESHF at our institution between 2022 and 2024. Patient demographics and follow-up data were comprehensively analyzed.

Article Synopsis
  • Mitral Valve Disease in children is challenging due to varying associated conditions, and repair is preferred over replacement because prosthetic valves can cause complications as children grow.
  • A study analyzed 47 pediatric patients who underwent mitral valve repair from 2002 to 2023, finding a low early mortality rate of 6.3% and encouraging long-term survival rates of 93.6% at one year and 91.4% at ten years.
  • The results suggest that mitral valve repair provides favorable outcomes, with an 85.1% rate of freedom from re-operation at ten years, indicating that individualizing treatment based on patient growth and specific conditions can maximize success.

End-stage Fontan patients with single-ventricle (SV) circulation are often bridged-to-heart transplantation via mechanical circulatory support (MCS). Donor shortage and complexity of the SV physiology demand innovative MCS. In this paper, an out-of-the-box circulation concept, in which the left and right ventricles are switched with each other is introduced as a novel bi-ventricle MCS configuration for the "failing" Fontan patients.

A 66-year-old man had an enlarging aortic aneurysm sac after an endovascular aortic replacement procedure that had been performed at another institution 4 years previously; it was without any endoleak but was complicated by the occlusion of the left limb, requiring cross-femoral bypass. Current computed tomography revealed dilatation of the proximal neck and the right common iliac artery. A type Ib endoleak was found from the distal end of the right limb of the endograft, possibly secondary to the dilatation of the artery around it; it then pressurized and caused the dilatation of the juxtarenal aorta around the proximal landing zone and induced a concomitant type Ia endoleak.

Objectives: A new congenital heart surgery database (CKCV) with real-time online reporting function was recently developed in Turkey. All standard international parameters were used, but Aristotle Comprehensive Complexity score was modified. In this study, the first analysis of the CKCV Database is reported.

Article Synopsis
  • Left ventricular assist devices (LVADs) are crucial for treating end-stage heart failure by providing mechanical circulatory support.
  • Organ donations from brain-dead donors on mechanical support are uncommon, but there are documented cases of successful solid-organ transplants from such donors.
  • This is the first reported case of a successful solid-organ transplant from a child donor who was using a nonpulsatile ventricular assist device.

Our aim was to investigate whether there is an association between caregivers' coping and children's psychiatric symptoms and quality of life in adolescent heart transplant (HTx) recipients and HTx candidates with left ventricular assist device (LVAD). Fourteen patients were recruited for this pilot study (HTx (n = 8), LVAD (n = 6)). Schedule for Affective Disorders and Schizophrenia for School Aged Children, Present and Lifetime Version (K-SADS) was administered to detect the psychiatric diagnosis of patients.

Background: The aim of this study was to investigate the efficiency of tricuspid valve detachment (TVD) during the surgical treatment of perimembranous ventricular septal defects (VSDs) and to compare the early and mid-term results to patients without TVD in terms of tricuspid insufficiency.

Methods: A total of 170 patients who had undergone surgical closure of perimembranous VSDs between November 2012 and January 2019 were included in this study, of whom 50 had an additional TVD procedure during the surgery. All patients were examined by transthoracic echocardiography before and after the operation with regular intervals, and the tricuspid valve function was then evaluated.

Supravalvular aortic stenosis, which is a rare congenital cardiac anomaly, is associated with several lesions and has a progressive nature. Herein, we report a five-year-old girl with bicuspid aorta who underwent initial Doty operation at the age of nine months. A combined redo Doty operation and an aortic valve commissurotomy were performed two years later.

Objective: This study aimed to evaluate the early operative outcomes and to compare the left ventricle and mitral valve functions after initial Takeuchi repair in patients with anomalous left coronary arising from pulmonary artery (ALCAPA).

Methods: Fourteen patients (5 males, 9 females; mean age 4.3 years, ranging from 25 days to 34 years) who were operated for ALCAPA between 2007 and 2018 were included in this study.

Although various modalities are currently in use to define pediatric aortic arch hypoplasia (AAH), there is little uniformity among them. We aimed to determine the inter-rater strength of agreement of the nomograms in a survey of patients less than 1 year old, who had undergone coarctation of the aorta (CoA) repair with or without AAH. This retrospectively designed study comprised of 105 patients with CoA, who had been evaluated between 2008 and 2018 by means of a computed tomography angiogram.

Although pulmonary venous baffle stenosis is not a common late complication after the Senning operation, surgical treatment is vital, when interventional methods fail to correct the pathology. Our patient was admitted to hospital with recurrent epistaxis and exertional dyspnea 6.5 years after the Senning procedure.

Baraitser-Winter syndrome is a very rare genetic disorder caused by cytoplasmic actin-encoding genes defects. Although most patients have similar phenotype, concomitant cardiac anomalies widely vary. In addition to well-described congenital heart diseases, aortic aneurysms occur due to underlying actin gene mutation in these patients in the further years.

The study aimed to revisit the in-hospital predictors of shunt thrombosis (ST) in the foreground of the pulmonary artery size in patients who received modified Blalock-Taussig shunt (mBTS) as the first-stage palliation. Data from 80 patients who received mBTS as their initial palliative procedure between February 2012 and January 2017 was retrospectively collected. The median age and weight of the patients at the time of their mBTS procedure was 4 days (IQR 2-22 days) and 3.

Background: Endothermal treatment of the great saphenous vein has become the first line of treatment for superficial venous reflux. A new technique for venous insufficiency is non-thermal ablation with vein sealing system which comprises the endovenous delivery of cyanoacrylate tissue adhesive to the vein causing fibrosis.

Methods: This is a single-center prospective study of treatment of great saphenous vein incompetence in 62 patients with vein sealing system (Biolas VariClose FG Group, Turkey).

Percutaneous atrial septal defect (ASD) closure has become an increasingly simplified procedure over the past decade. The device embolization is seen rarely but it can be fatal. Although percutaneous retrieval is feasible, surgical removal might be preferred when the endothelialization status of the device is unknown.

Synovial sarcoma (SS), a mesenchymal spindle cell tumor, displays variable epithelial differentiation, including glandular formation, and features a specific chromosomal translocation, t(X;18)(p11;q11). SS accounts for 5% to 10% of soft-tissue sarcomas. These tumors occur mostly in the joints, especially near the knee, but they also occur in other locations.
