Association between caregivers' coping and children's psychiatric symptoms in the heart transplantation process: A pilot study.

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. Children's Depression Inventory (CDI), State-Trait Anxiety Inventory, and Pediatric Quality of Life Inventory (PedsQL) were completed by adolescents; Brief Coping Styles Inventory by their caregivers. Six of the participants had an internalizing disorder. Optimistic coping strategy score was significantly higher in the caregivers of adolescents without an internalizing disorder than caregivers of those with an internalizing disorder (U = 2.500, P = .005). Utilizing Spearman's correlation, caregivers' optimistic approach (rho = -0.736, P = .004), and self-confident approach (rho = -0.634, P = .020) had significant negative correlations with children's CDI scores. Moreover, caregivers' optimistic approach score had a significant positive correlation with children's PedsQL score (rho = 0.563, P = .045). According to our preliminary results, it seems that caregivers' optimistic and self-confident coping strategies may be associated with fewer internalizing symptoms and a better quality of life in adolescents in the HTx process. A future multicentered longitudinal study will be planned to assess the effect of caregivers' coping strategies on the psychological adjustment of these children.

Can urinary biomarkers predict acute kidney injury in newborns with critical congenital heart disease?

BACKGROUND: Congenital heart disease (CHD) is the most common congenital malformation group and is the leading cause of newborn mortality in developed countries. Most of the infants with CHD develop preoperative or postoperative acute kidney injury (AKI). Acute kidney injury may develop before the serum creatinine rise and oliguria. Urinary biomarkers such as kidney injury molecule-1 (KIM-1), neutrophil gelatinase-associated lipocalin (NGAL), interleukin (IL)-18, and cystatin C may predict AKI in patients with critical CHD (CCHD) before the serum creatinine rise. In this study, we aimed to determine the AKI incidence among newborn patients with CCHD and investigate the predictivity of urinary biomarkers for AKI. METHODS: Newborns with a gestational age >34 weeks and birth weight >1500 g with a diagnosis of CCHD were enrolled in the study. Blood and urine samples were collected at birth, during the first 24-48 h, and in the preoperative and postoperative periods. RESULTS: A total of 53 CCHD patients requiring surgery during the neonatal period were enrolled in the study. The 24-48 h KIM-1 levels of the cases with exitus were higher (P = 0.007). The 24-48 h cystatin C and preoperative NGAL levels were higher in patients with postoperative AKI (P = 0.02). DISCUSSION: In newborns with CCHD, high KIM-1 levels may predict mortality, whereas high cystatin C and preoperative NGAL levels may be indicative of AKI. These biomarkers deserve further investigation in larger study populations.

Assessment of Tricuspid Valve Detachment Efficiency for Ventricular Septal Defect Closure: A Retrospective Comparative Study.

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. RESULTS: There was no significant difference between subgroups with an unchanging degree of TVR, however, the result was also similar among those who had a decreased degree of TVR at any level (p = 0.271, p = 0.451). At the end of the study, all patients were in New York Heart Association class I. CONCLUSIONS: We suggest that, in appropriate patients, VSD closure can be safely performed with an additional TVD application through an incision of the septal leaflet of the tricuspid valve without impairing the valve function or reducing the growth potential of the valve at midterm follow-up.

Blalock-Taussig Shunt Size: Should it be Based on Body Weight or Target Branch Pulmonary Artery Size?

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 3.2 kg (IQR 2.8-3.7 kg), respectively. Of the 80 patients in the study, 11 (13.8%) developed ST. The diameter and corresponding z scores of the pulmonary arteries were significantly lower in patients with ST. The median shunt size/shunted pulmonary artery size (S/PA) ratio was considerably higher in patients with ST. In logistic regression analysis, pulmonary artery hypoplasia (PAH) [odds ratio (OR) = 13.7 (0.06-0.21), p < 0.001], S/PA ratio ≥ 0.9 [OR = 8.1 (0.03-0.53), p = 0.03], prematurity [OR = 9.5 (0.05-0.33), p = 0.003], and shunt size/weight (S/W) ratio ≥ 1.3 [OR = 6.4 (0.04-0.67), p = 0.012] were found to have a significant impact on ST. The best combination of sensitivity and specificity of the S/W (0.73 and 0.75) and the S/PA ratio (0.73 and 0.80) were achieved at the cut-off value of 1.3 and 0.9, respectively. The Youden index of S/PA was 0.52. While the area under the curve (AUC) of the S/W ratio was 0.686 ± 0.12 (p = 0.049), the AUC of the S/PA ratio was 0.791 ± 0.08 (p = 0.002). In conclusion, instead of weight, considering the size of the target pulmonary artery and thereby, the S/PA ratio would be more instructive in determining shunt size. There were a high number of patients in our study who showed PAH having received a shunt size based on their body weight. By contrast, our results showed that the S/PA ratio of ≥ 0.9 would be a good predictor of in-hospital ST.

Comparison Between Nomograms Used to Define Pediatric Aortic Arch Hypoplasia: Retrospective Evaluation Among Patients Less Than 1 Year Old with Coarctation of the Aorta.

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. Through re-estimation of the aortic arch segmental diameters, the z scores were calculated using three nomograms (Cantinotti, Pettersen, Lopez). Along with a t test and Pearson's correlation coefficient, a linear regression analysis, Bland-Altman plots, and Cohen's kappa k value were used to evaluate inter-rater strength of agreement. The mean age and weight of the cohort was 73.3 ± 81.2 days and 4.2 ± 1.6 kg, respectively. Sixty-four (61%) patients were neonates. The z scores of the nomograms for each aortic arch segment were significantly different. Although there was a significantly positive correlation between the nomograms with their related aortic arch diameter, the differences in z scores revealed considerable deviations in the scatter plot diagrams. The mean difference of z scores was significantly different from the testing value of zero, which was also presented in Bland-Altman plots. None of the comparisons reached a kappa k value of > 0.9. The current nomograms do not reveal an acceptable level of agreement for the definition of the AAH. The question is which modality to rely on when deciding on the surgical approach and technique of CoA repair to address the hypoplastic aortic arch segment. Decisions about the surgical approach and the technique of repair warrant a reliable definition of AAH. It is high time that a consensus is reached in this regard.

Cor triatriatum sinister: a case series.

OBJECTIVE: As a highly rare congenital defect, cor triatriatum sinister represents only 0.1% of congenital cardiac anomalies. Depending on the degree of obstruction and the accompanying symptoms, cor triatriatum can be diagnosed at any age. This case series described 5 patients with cor triatriatum sinister who underwent operation. METHODS: Five patients with cor triatriatum sinister were seen at our institution between 2007 and 2013. The demographic characteristics and surgical results of these patients are outlined in this retrospective review. RESULTS: The surgical approach consists of left or right atriotomy, excision of the obstructing membrane, and repair of the associated intracardiac anomalies. After an uneventful postoperative hospital stay, all patients were discharged 5-10 days postoperatively. There were no instances of recurrent constriction after surgical treatment of the cor triatriatum membrane. Patients were followed up for a median of 4 years and were symptom free. CONCLUSION: In the surgical management of this easily and fully treatable congenital cardiac anomaly, it is difficult to determine which atriotomy approach is comparatively more advantageous. However, in the management of cor triatriatum sinister, priority should be given to confirmation of the diagnosis and full resection of the membrane. Thus, the surgeon should not hesitate to perform additional incisions if deemed necessary.

Right Anterolateral Thoracotomy in the Repair of Atrial Septal Defect: Effect on Breast Development.

BACKGROUND AND AIM: The aim of this study was to assess the cosmetic results and the impact on the breast development of a right anterolateral thoracotomy (RALT) in pre-pubertal children who underwent RALT for correction of atrial septal defects. METHODS: From December 2002 to July 2010, 25 female patients with a mean age of 8.5 ± 1.3 years underwent repair of atrial septal defects with a right anterolateral thoracotomy. Breast symmetry was described by a clinical index. The degree of scoliosis was measured by clinical examination. The subjective evaluation in breast asymetry, size, and shape was assessed by a survey obtained by the patients. RESULTS: There was no intraoperative or postoperative complication or late mortality in the thoracotomy approach or in the long-term follow-up (7.5 ± 2.2 years). According to the survey, breast asymmetry and differences between both breast size or shape were found in 15 (60%) and seven (28%) patients, respectively. One patient (4%) complained of a keloid scar. Mild sensitive skin deficit in the mammary area was determined in four patients (16%). According to the objective assessment, breast asymmetry was found 12 patients (48%) with index 1 and 13 patients (52%) with index 2. CONCLUSION: Although it is safe, the RALT is associated with the potential to effect unilateral breast development.

[Late development of double-chambered right ventricle after repair of a ventricular septal defect]. / Ventriküler septal defekt onarimi sonrasi geç dönemde gelisen çift odacikli sag ventrikül.

Double-chambered right ventricle is a rare heart defect causing right ventricular outflow tract (RVOT) obstruction. In this malformation, the right ventricle is divided into two chambers by a fibromuscular band. A 12-year old female patient who had undergone repair of a ventricular septal defect at 5 months old was admitted to our hospital with complaints of dyspnea and fatigue. The patient was diagnosed with an isolated double-chambered right ventricle and surgical correction was successfully performed. Post-operative transesophageal echocardiography showed no residual gradients across the RVOT. Following an uneventful recovery, the patient was discharged five days after surgery.

Second harvest of Congenital Heart Surgery Database in Türkiye: Current outcomes.

Background: This second harvest of the Congenital Heart Surgery Database intended to compare current results with international databases. Methods: This retrospective study examined a total of 4007 congenital heart surgery procedures from 15 centers in the Congenital Heart Surgery Database between January 2018 and January 2023. International diagnostic and procedural codes were used for data entry. STAT (Society of Thoracic Surgeons and European Association for Cardiothoracic Surgery) mortality scores and categories were used for comparison of the data. Surgical priority status was modified from American Society of Anesthesiologist guidelines. Centers that sent more than 5 cases to the database were included to the study. Results: Cardiopulmonary bypass and cardioplegic arrest were performed in 2,983 (74.4%) procedures. General risk factors were present in 22.6% of the patients, such as genetic anomaly, syndrome, or prematurity. Overall, 18.9% of the patients had preoperative risk factors (e.g., mechanical ventilation, renal failure, and sepsis). Of the procedures, 610 (15.2%) were performed on neonates, 1,450 (36.2%) on infants, 1,803 (45%) on children, and 144 (3.6%) on adults. The operative timing was elective in 56.5% of the patients, 34.4% were urgent, 8% were emergent, and 1.1% were rescue procedures. Extracorporeal membrane oxygenation support was used in 163 (4%) patients, with a 34.3% survival rate. Overall mortality in this series was 6.7% (n=271). Risk for mortality was higher in patients with general risk factors, such as prematurity, low birth weight neonates, and heterotaxy syndrome. Mortality for patients with preoperative mechanical ventilation was 17.5%. Pulmonary hypertension and preoperative circulatory shock had 11.6% and 10% mortality rates, respectively. Mortality for patients who had no preoperative risk factor was 3.9%. Neonates had the highest mortality rate (20.5%). Intensive care unit and hospital stay time for neonates (median of 17.8 days and 24.8 days, respectively) were also higher than the other age groups. Infants had 6.2% mortality. Hospital mortality was 2.8% for children and 3.5% for adults. Mortality rate was 2.8% for elective cases. Observed mortality rates were higher than expected in the fourth and fifth categories of the STAT system (observed, 14.8% and 51.9%; expected, 9.9% and 23.1%; respectively). Conclusion: For the first time, outcomes of congenital heart surgery in Türkiye could be compared to the current world experience with this multicenter database study. Increased mortality rate of neonatal and complex heart operations could be delineated as areas that need improvement. The Congenital Heart Surgery Database has great potential for quality improvement of congenital heart surgery in Türkiye. In the long term, participation of more centers in the database may allow more accurate risk adjustment.

Anomalous origin of the left coronary artery from the pulmonary artery presenting as dilated cardiomyopathy.

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital anomaly and one of the causes of myocardial ischemia. It often presents with atypical signs and symptoms, especially in childhood. In this case report, an 11-year-old girl presented with dilated cardiomyopathy in our clinic and was followed for five years. Echocardiography showed multiple left-to-right shunts on the interventricular septum, the confirmation of which was done by multi-slice computed tomography and coronary angiography. Therefore, we suggest that ALCAPA should be suspected in young patients diagnosed with dilated cardiomyopathy.

Switching the Left and the Right Hearts: A Novel Bi-ventricle Mechanical Support Strategy with Spared Native Single-Ventricle.

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. In the proposed configuration, the systemic circulation is maintained through a conventional mechanical ventricle assist device (VAD) while the venous circulation is delegated to the native SV. This approach spares the SV and puts it to a new use at the right-side providing the most-needed venous flow pulsatility to the failed Fontan circulation. To analyze its feasibility and performance, eight SV failure modes have been studied via an established multi-compartmental lumped parameter cardiovascular model (LPM). Here the LPM model is experimentally validated against the corresponding pulsatile mock-up flow loop measurements of a representative 15-year-old Fontan patient employing a clinically-approved VAD (Medtronic-HeartWare). The proposed surgical configuration maintained the healthy cardiac index (3-3.5 l/min/m2) and the normal mean systemic arterial pressure levels. For a failed SV with low ejection fraction (EF = 26%), representing a typical systemic Fontan failure, the proposed configuration enabled a ~ 28 mmHg amplitude in the venous/pulmonary waveforms and a 2 mmHg decrease in the central venous pressure (CVP) together with acceptable mean pulmonary artery pressures (17.5 mmHg). The pulmonary vascular resistance (PVR)-SV failure case provided a ~ 5 mmHg drop in the CVP, with venous/pulmonary pulsatility reaching to ~ 22 mmHg. For the high PVR failure case with a healthy SV (EF = 44%) pulmonary hypertension is likely to occur as expected. While this condition is routinely encountered during the heart transplantation and managed through pulmonary vasodilators a need for precise functional assessment of the spared failed-ventricle is recommended if utilized in the PVR failure mode. Comprehensive in vitro and in silico results encourage this novel concept as a low-cost, more physiological alternative to the conventional bi-ventricle MCS pending animal experiments.

Psychiatric evaluation of children and adolescents with left ventricular assist devices.

OBJECTIVES: To evaluate the psychiatric symptoms of children equipped with a ventricular assist device (VAD) and follow them up for 6 months. With the shortage of donor hearts available for the treatment of end-stage heart failure, VADs have been used to provide temporary treatment until a heart becomes available. VADs provide external sources of power for mechanical circulatory support and are capable of sustaining life over weeks and months. This study provides preliminary details about the psychiatric symptoms and disorders of the first eight children equipped with a VAD in Turkey. METHODS: Eight pediatric patients who recently underwent VAD implantation, aged 1 to 16 years, were evaluated using the Kiddie Schedule for Affective Disorders and Schizophrenia, Child Behavior Checklist, Children's Depression Inventory, Beck Depression Inventory, and State-Trait Anxiety Inventory for Children and followed up for 6 months. RESULTS: In the first evaluation, five participants had a psychiatric disorder diagnosis. Two patients had adjustment disorder with depressive and anxiety symptoms; one had anxiety disorder, not otherwise specified; and two had major depressive disorder. The anxiety and depressive symptom levels in questionnaires were consistent with psychiatric diagnoses. Two patients had heart transplantation during the follow-up period. CONCLUSIONS: To determine and treat psychiatric symptoms and disorders at an earlier stage, it is important for children and adolescents with a VAD and those who have undergone heart transplantation to be evaluated by a multidisciplinary consultation liaison team including psychiatrists, psychologists, consultant nurses, and counselors.

An experience in the COVID-19 pandemic period: Turkish Cardiovascular Surgery Online Board Exam 2020.

Background: The aim of this study was to provide information about the results of the Turkish Cardiovascular Surgery Board written exam, which was held online due to the pandemic. Methods: This cross-sectional study included a total of 41 cardiovascular surgeons and residents (39 males, 2 females) in November 21st, 2020 between 10:00 A.M. and 12:00 P.M. After the online exam was completed, data on participant information and answers to exam questions were obtained from the information system. Results: Of all participants, 39% were working in university hospitals. A total of 82.9% of the participants were specialists. The total mean score of the participants was 60.3±10.2 and 53.7% of them were declared successful-passed. Aortic surgery (63%), heart failure surgery (50%), and mitral valve surgery (50%) were the most incorrectly answered questions. Conclusion: With the online exam, the Board gained different experiences regarding exam planning and implementation. The Turkish Cardiovascular Surgery Board did not give up the Board exam during the pandemic period and conducted a reliable written exam with many participants.

Surgical repair of middle aortic syndrome in a three-year-old patient.

Middle aortic syndrome is a rare variation of aortic coarctation that is localized to the distal thoracic and abdominal aorta, and can involve the visceral and renal arteries. Irreversible organ damage and end-stage congestive heart failure may be the possible harmful complications of this disease in untreated patients. We report a three-year-old patient with diffuse thoracic and abdominal aorta hypoplasia treated with a thoracic to abdominal aortic bypass graft.

A case of mitral papillary muscle rupture due to blunt chest trauma.

Mitral regurgitation due to papillary muscle rupture after blunt chest trauma is uncommon. Sudden onset severe mitral regurgitation may lead to death due to heart failure if surgical repair is delayed. A previously healthy 12-year-old girl underwent splenectomy and chest tube insertion for pneumothorax after a traffic accident in a vehicle 15 days before. She was discharged from the hospital after a nine-day follow-up. She was presented to our hospital due to respiratory distress. On physical examination, an apical holosystolic murmur radiating to the axillary region was recognized. Transthoracic echocardiogram showed severe mitral regurgitation with freely moving posterior mitral chordae and prolapse of the posterior mitral valve leaflet. She received reimplantation of the complete ruptured posteromedial papillary muscle of the mitral valve. Her medical condition improved after the operation. On the postoperative echocardiogram, the left ventricular systolic function was normal with no mitral regurgitation.

First Harvest of Pediatric and Congenital Heart Surgery Multicenter Database in Turkey: Novel Application of Real-Time Online Reporting.

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. METHODS: The CKCV Database included 2307 procedures from 12 centers between January 2018 and March 2020. All parameters, including 10 real-time online reports, which represent the number of centers, number and mortality rates of all procedures, number of extracorporeal membrane oxygenation (ECMO) and results, details of postoperative complications, age-group statistics, analysis for priority status, mean intensive care and hospital stay durations of the procedures, results of Aristotle Basic, Modified Aristotle Comprehensive (MACC) and Society of Thoracic Surgeons-European Association (STAT) Score Categories, comparison of centers were analyzed. RESULTS: Most common 10 procedures were ventricular septal defect (VSD) repair (n = 273), tetralogy of Fallot (TOF) repair (n = 243), atrial septal defect (ASD) repair (n = 181), complete AVSD repair (n = 95), cavopulmonary anastomosis (n = 81), systemic to pulmonary shunt (n = 79), modified Fontan (n = 71), subaortic resection, (n = 66) PA banding (n = 66), and arterial switch operation (n = 66). Cardiopulmonary bypass was used in 84.6% of the procedures. Overall mortality rate was 6.0%. A total of 618 major and 570 minor complications were observed in 333 and 412 patients, respectively. According to six MACC categories, number of the patients and mortality rates were I (293; 0.3%); II (713; 1.4%); III (601; 3.3%); IV (607; 12%); V (84; 35.7%); and VI (9; 55.6%), respectively. Analysis of five STAT Categories showed 0.7, 3.8, 5.4, 14.9, and 54.7% mortality rates. CONCLUSIONS: CKCV Database has a great potential for nationwide quality improvement studies. Users could instantly analyze and compare their results to national and international aggregate data using a real-time online reporting function. This is the first multicenter congenital database study in Turkey.

Effect of pleurotomy on blood loss during coronary artery bypass grafting.

BACKGROUND: We conducted a retrospective study to compare two different techniques of internal mammarian artery (IMA) preparation concerning pleurotomy upon the effects of blood loss and pulmonary functions. METHODS: Between January 1998 and November 2006, 1357 consecutive patients undergoing coronary artery bypass grafting (CABG) using the left IMA, either alone or in combination with saphenous vein graft, were included in this study. The patients were divided into two groups according to the pleural opening: Group I (n = 1046) patients underwent IMA harvesting with pleurotomy and Group 2 (n = 311) patients with intact pleura. RESULTS: During the study, 27 hospital deaths (1.9%) occurred. The amount of postoperative blood loss and blood transfusion requirements were significantly higher in Group 1 than in Group 2 (p = 0.029 and p = 0.0001). The mechanical ventilation stay was significantly higher in Group 1 than in Group 2 (p = 0.0001). The incidence of left pleural effusion and atelectasis was significantly higher in Group 1 than in Group 2 on day 1 and day 3 after operation. CONCLUSIONS: These results demonstrate that preserving pleural integrity has beneficial effects on the postoperative blood loss. Postoperative blood loss and transfusion requirements were higher in patients with pleurotomy. Left pleural effusion, atelectasis, and mechanical ventilatory stay were significantly reduced in patients with preserved pleural integrity.

Requirement for repetitive surgical approaches at supravalvular aortic stenosis.

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. Due to the rapidly progressing aortic regurgitation and both valvular and supravalvular gradient, a repeated surgery was required at the age of five years and an aortic homograft was successfully inserted with an annulus enlargement and the patient was discharged uneventfully. In conclusion, although Doty repair yields satisfactory results in most patients, certain cases with identified risk factors may require reoperations due to the progressive nature of the disease. Therefore, these patients should be kept under a close follow-up lifelong.
