Objective: Myocarditis is a non-ischemic inflammation of the cardiac muscle and causes non-specific and variable electrocardiographic (ECG) changes, indicating the inflammatory process. In this study, we aimed to investigate the prevalence and nature of ECG changes and arrhythmias in patients diagnosed with acute myocarditis (AM). Materials and Methods: This retrospective study included 75 patients diagnosed with AM between January 1, 2020, and December 31, 2022, at our institution. The diagnosis was based on clinical symptoms, laboratory findings, and imaging procedures. Results: Of the 75 AM patients evaluated, 67 (89.3%) were male, with a median age of 15 years. The primary symptom was chest pain (89.3%). The peaking times of Troponin I levels varied in presentation times. Elevated creatine kinase-MB and C-reactive protein levels were observed in 62.7% and 78.7% of patients, respectively. Viral serology identified COVID-19, Coxsackievirus, influenza, and parainfluenza as common viruses. ECG and Holter abnormalities were found in 82.7% of patients, with ST-segment elevation, T-wave abnormalities, sinus tachycardia, and interventricular conduction delay being the most common. Extracorporeal membrane oxygenation therapy was required in two critical cases, unfortunately resulting in the deaths of both patients. Conclusion: Myocarditis presents with varied etiology and manifestations. ECG changes and arrhythmias are commonly observed in patients with this condition. Despite comprehensive care, severe cases can lead to adverse outcomes. [ABSTRACT FROM AUTHOR]

Objective: Aortopulmonary window (APW) is an uncommon congenital cardiac abnormality marked by a septation defect between the ascending aorta and pulmonary artery. This study aimed to define the clinical characteristics, diagnostic features, treatment strategies, and follow-up outcomes of pediatric patients diagnosed with APW. Material and Methods: We retrospectively reviewed children diagnosed with APW from 2010 to 2023. Morphological APW typing of our patients was based on the classification that is settled by the Society of Thoracic Surgeons (STS) Congenital Heart Surgery Database Committee. The patients' demographic data, symptoms at admission, transthoracic echocardiography, cardiac computed tomography, management modalities, and follow-up data were evaluated. Results: Twenty-five children were diagnosed with APW over the study period. Thirteen patients were male (52%), and the median age at presentation of the patients was three months (8 days-7.5 years). Two patients were diagnosed with coronary fistula by echocardiography at the first admission and were diagnosed with APW after catheterization. APW was detected in one patient while being operated on for large ventricular septal defect. According to the STS classification, 32% (n=8) of the patients were type III, 32% (n=8) were type I, 16% (n=4) were intermediate type, 12% (n=3) were type II, and 4% (n=1) were APW with aortic interruption. Associated cardiovascular malformations were in 76% (n=19) of the patients. Fifteen patients (60%) underwent surgery. Transcatheter closure of APW was performed in four patients (16%). Conclusion: Detection of the APW requires careful and systematic investigation. Transcatheter closure can be performed in selected cases where the defect is suitable. Although rare, this defect, which can cause severe left-right shunting, should be kept in mind as a cause of pulmonary hypertension and unexplained cardiac dilation and should be investigated in patients whose cause cannot be determined.

Introduction: Various valve repair techniques have been described for prevention of pulmonary insufficiency (PI) during right ventricular outflow tract (RVOT) reconstruction with transannular patch. Herein, we present the early results of an alternative technique of neopulmonary valve reconstruction using right atrial appendage (RAA) tissue.Methods: Between October 2019 and December 2019, 12 patients with tetralogy of fallot (TOF) (n = 10), TOF-absent pulmonary valve (n = 1) and intact ventricular septum-pulmonary atresia (n = 1) underwent RVOT reconstruction with neopulmonary valve that was created using RAA tissue. Median age and weight of patients were 9.9 months (5 months-14 years) and 9.8 kg (6.2-47), respectively.Results: No mortality or major events developed. Postoperative echocardiography revealed none/trace PI in 11 patients and mild PI in 1 patient. Median right ventricle/left ventricle ratio was 0.46 (0.35-0.65) and RVOT gradient was 20 mm Hg (0-30). Median cardiopulmonary bypass and aortic clamping times were 121 minutes (81-178) and 94 minutes (59-138), respectively. Operative times revealed statistically significant learning curve pattern in terms of cardiopulmonary bypass (r2  = .568; P = .005) and aortic clamping times (r2  = .635; P = .002). Median ventilation time, intensive care unit stay, and the length of hospital stay were 6 hours (2-48), 1 days (1-5), and 7 days (4-10), respectively. Longer perfusion time was not correlated with postoperative times. At median 6 months, echocardiography showed none/trivial PI in 11 patients and mild PI in one patient.Conclusion: Early results showed that neopulmonary valve reconstruction using the RAA tissue may provide a reasonable alternative for RVOT reconstruction with transannular patch. But long-term results are needed. [ABSTRACT FROM AUTHOR]

Background: Prolonged pleural drainage is a common complication after undergoing the Fontan procedure. Although various protocols have been described, there is no definitive consensus for how to treat this complication.Materials and Methods: Our primary aim was to determine the effect of the management strategy protocol on the duration of drainage and length of hospital stay. Our secondary aim was to determine the parameters affecting the need for prolonged drainage after the Fontan procedure. Ninety-two consecutive patients who underwent the Fontan procedure were retrospectively analyzed. A protocol-based postoperative management strategy was adopted in July 2018. Group 1 (n = 48) consisted of patients that underwent the procedure before the protocol was implemented. Group 2 (n = 44) consisted of patients that underwent the procedure after the protocol was implemented.Results: The mean age was 5 years (interquartile range [IQR], 4.0-6.9); the mean body weight was 17.3 kg (IQR, 15.1-21.8). Statistically significant differences were found between the groups in terms of total drainage, duration of pleural drainage, prolonged drainage, and length of hospital stays (LOHS) (P = .05, P = .04, P = .04, P = .04, respectively). The multivariate analysis results showed that the application of the protocol was the only factor impacting prolonged drainage (OR, 2.46, 95% CI lower-upper: 1.03-5.86, P = .04).Conclusion: Standardization and strict application of the medical treatment within a specific protocol without being affected by doctor-, nurse-, or patient-based factors increases the success rate of this procedure. After implementing the changes in the medical management strategy, total drainage and duration of pleural drainage and LOHS decreased, and the costs associated with these factors also decreased.

Objective: To reveal the risk factors that can lead to a complicated course and an increased morbidity in patients < 1 year old after surgical ventricular septal defect (VSD) closure. Methods: We reviewed a consecutive series of patients who were admitted to our institution for surgical VSD closure who were under one year of age, between 2015 and 2018. Mechanical ventilation (MV) time > 24 hours, intensive care unit (ICU) stay longer than three days, and hospital stay longer than seven days were defined as "prolonged". Unplanned reoperation, complete heart block requiring a permanent pacemaker implantation, sudden circulatory arrest, and death were considered as significant major adverse events (MAE). Results: VSD closure was performed in 185 patients. The median age was five (1-12) months. There was prolonged MV time in 54 (29.2%) patients. Four patients (2.2%) required permanent pacemaker implantation. Hemodynamically significant residual VSD was observed in six (3.2%) patients. Extracorporeal membrane oxygenation-cardiopulmonary resuscitation was performed in one (0.5%) patient. Small age (< 4 months) (P-value<0.001) and prolonged cardiopulmonary bypass time (P=0.03) were found to delay extubation and to prolong MV time. Low birth weight at the operation was associated with MAE (P=0.03). Conclusion: Higher body weight during operation had a reducing effect on the MAE frequency and shortened the MV duration, ICU stay, and hospital stay. As a conclusion, for patients who are scheduled to undergo VSD closure, body weight should be taken into consideration. [ABSTRACT FROM AUTHOR]

The article presents a case study of a 12-year-old male patient with a murmur and pectus carinatum and dysmorphic features of dolichocephaly, palpebral fissures and scoliosis. It mentions a computed tomography evaluation which revealed aneurysmatic dilatation from the aortic root to the right truncal brachiocephalic branch. It also states detection of mutation of heterozygous missense in the TGFBR2 gene.

Introduction: Extracorporeal membrane oxygenation (ECMO) has become a standard technique over the past few decades in intensive care unit (ICU). Objective: A review of pediatric patients who received ECMO support in the pediatric cardiac ICU was conducted to determine the incidence, risk factors and causal organisms related to acquired infections and assess the survival rates of ECMO patients with nosocomial infections. Methods: Sixty-six patients who received ECMO support in the pediatric cardiac ICU between January 2011 and June 2014 were included in the study. Demographic, echocardiographic, hemodynamic features and surgical procedures were reviewed. Results: Sixty-six patients received a total of 292.5 days of venoarterial ECMO support. Sixty were postoperative patients. Forty-five patients were weaned from ECMO support with an ECMO survival rate of 68.2%. The rate of infection was 116.2/1000 ECMO days. Prolonged ICU stay, duration of ventilation and ECMO were found associated with development of nosocomial infection and only the duration of ECMO was an independent risk factor for nosocomial infections in ECMO patients. Conclusion: The correction of the underlying process leading to ECMO support and shortening the length of ECMO duration together with stricter application of ECMO indications would improve the infection incidence and hospital surveillance of the patient group.

Univentricular heart is a rare congenital defect that consists, in nearly 80% of cases, of double inlet left ventricle, to which both atrioventricular valves connect. A 31-year-old male patient was diagnosed with single ventricle at the age of 9. He had not received any surgical intervention and was not on any medication. Functional capacity was assessed as New York Heart Association class III. Both atrioventricular valves were found to open into the morphological left ventricle, which was located on the right; the hypoplasic right ventricle was on the left side of the left ventricle, the posteriorly located aorta emerged from the right ventricle, and the anteriorly located pulmonary artery emerged from the left ventricle. There was significant subvalvular and valvular stenosis in the pulmonary valve site. The disease is complex and it is very rare that untreated patients reach adulthood. [ABSTRACT FROM AUTHOR]

The article presents a case study of a 8-month-old girl, who was weighing six kilograms and was referred for surgery. Topics discussed include conduction of Glenn anastomosis of the patient; diagnosis of severe bilateral pulmonary venous stenosis during computed tomography angiography; and performing Fontan-Kreutzer palliation and pulmonary venous connection repair.

The article presents a case study of 2-month-old female patient who has recovered from severe cyanosis and respiratory distress. The patient had Vertical Veins (VVs) in which pulmonary veins had drained into systemic veins. She had undergone stent implantation to the stenotic VVs to relieve the obstruction. It discusses heterotaxy syndromes in which changeability can be considered in pulmonary to systemic venous connection in all forms of total anomalous pulmonary venous connection (TAPVC).

Background: This study aimed to evaluate patients diagnosed with posterior transposition of the great arteries (TGA) in detail., Methods: This retrospective study included 192 patients (155 males, 37 females; mean age: 0.4±0.9 month; range, 0.1 to 6 month) with TGA who were followed between August 1, 2016, and August 1, 2022. Patients with ventriculoarterial discordance, normal vessel relationship, and mitral-aortic continuity were considered posterior TGA. Demographic features, clinical findings, echocardiographic data, and surgical results of each patient were recorded., Results: Posterior TGA was present in 11 (5.7%) of the patients. The median age of patients with posterior TGA at the time of surgery was two months (interquartile range [IQR], 1-3 months), and their median body weight was 6.2 kg (IQR, 5-7.2 kg). The median oxygen saturation of the patients was 85% (IQR, 80-90%). A ventricular septal defect was present in all patients on echocardiography. There was also nonrestrictive atrial septal defect and patent ductus arteriosus in four patients, and one patient had arcus aorta hypoplasia. A coronary anomaly was determined in eight of the patients during surgery. These were 1LRCA2Cx in three cases, 1LRCx in three cases, 1R2LCx in one case, and 1L2RCx in one case. Arterial switch operation and ventricular septal defect closure was performed in 10 patients initially and in one patient after a pulmonary banding operation. The median cardiopulmonary bypass time was 190 min (IQR, 170-210 min). The Lecompte maneuver was not performed in any of the patients. The median stay in the intensive care unit and the hospital was 7 days (IQR, 5-10 days) and 16 days (IQR, 14-18 days), respectively. Two patients died in the early postoperative period., Conclusion: In patients with suspected congenital heart disease, a segmental echocardiographic evaluation should be performed, and it should be kept in mind that the aorta may be located posteriorly as a rare spatial relationship in patients with TGA., Competing Interests: Conflict of Interest: The authors declared no conflicts of interest with respect to the authorship and/or publication of this article., (Copyright © 2024, Turkish Society of Cardiovascular Surgery.)

Objective: Left ventricular non-compaction is a rare cardiomyopathy following an early arrest in endomyocardial morphogenesis. This study aimed to present the clinical and electrocardiographic characteristics, diagnostic features, treatment strategies, effects of systolic dysfunction on clinical and diagnostic parameters, and follow-up of pediatric patients diagnosed with left ventricular non-compaction., Methods: We retrospectively reviewed children with isolated left ventricular non-compaction at Mehmet Akif Ersoy Thoracic and Cardiovascular Surgery Training and Research Hospital from January 2010 to June 2020., Results: Fifty-five children were diagnosed with left ventricular non-compaction. Thirty-two patients (58.2%) were male, and the median age of presentation was 8.5 years (1 month-17.9 years). The median follow-up of the study was 19 months (1-121 months). Fourteen (25.5%) presented with systolic dysfunction (ejection fraction < 45%), and 2 presented with resuscitated/aborted cardiac arrest. Electrocardiographic abnormalities were present in 78.2%. Fragmented QRS was observed in 6 patients, and QTc duration was 450 milliseconds and above in 17 patients (30.9%). Electrocardiographic abnormalities, low QRS voltage, fragmented QRS, and thrombus were common in patients with ejection fraction < 45% group. Atrial and ventricular arrhythmias (including ventricular fibrillation-VF) were found with similar frequency in both ejection fraction < 45% and ≥45% groups. One patient with a complete atrioventricular block and 1 with long QT syndrome and severe bradycardia underwent permanent pacemaker implantation. Five (9.1%) patients died., Conclusions: Left ventricular non-compaction has heterogeneous clinical findings in childhood. It is essential to follow-up with the patients closely for the development of ventricular dysfunction or arrhythmias due to the progressive course of the disease. Further studies are needed since life-threatening ventricular arrhythmias can be seen, even in patients with preserved ejection fraction.

Objective: Levoatriocardinal vein (LACV) is a rare cardiac pathology that represents a connection between the pulmonary venous and cardinal systems. The aim of the present study was to discuss morphological and clinical characteristics, as well as diagnostic methods, of experience with LACV., Methods: Records of 11 patients (4 male, 7 female; mean age 79±1.83 days; range 1-390 days) diagnosed with LACV between 2010 and 2014 were retrospectively reviewed. Presence of LACV was confirmed with echocardiography. The primary obstructive lesion associated with cardiac defects and the integrity of the interatrial septum was identified in each patient with left-sided obstruction., Results: Mean weight was 4.4±0.4 kg (range: 2-8). Age at presentation was under 1 year in 82% of patients. Nine patients had left-sided obstruction, and 2 had normal intracardiac anatomy and pulmonary venous return. In patients with left-sided obstruction, LACV was initially demonstrated with echocardiographic evaluation, performed in apical 4-chamber, high parasternal, and subcostal views. Atrial septum was restrictive or intact in patients with left-sided obstructions. LACV originated directly from the left atrium in all patients., Conclusion: Levoatriocardinal vein is an extremely rare cardiac pathology, presenting almost exclusively in patients with left-sided obstructive lesions. In patients with left-sided obstructions, LACV must be kept in mind. It may also present in patients with normal intracardiac anatomy and pulmonary venous return.
