    Recommendations for the selection of techniques and components used in congenital heart surgery in Turkey
    (BAYCINAR MEDICAL PUBL-BAYCINAR TIBBI YAYINCILIK, 2012-01-01) Undar, Akif; Haydin, Sertac; Erek, Ersin; Yivli, Perihan; Odemis, Ender; Agirbasli, Mehmet; Alkan-Bozkaya, Tijen; Turkoz, Ayda; Turkoz, Riza; Sasmazel, Ahmet; Karaci, Ali Riza; Cicek, Ali Ekber; Yalcinbas, Yusuf; Akcevin, Atif; Sarioglu, Tayyar; Bakir, Ihsan
    There is no standard for the selection of technical and mechanical components (heart-lung machine system, oxygenator, arterial and venous cannulae, arterial filter and other specifically-designed components and devices) used in cardiopulmonary bypass in Turkey. The cost of the component plays a significant role in the selection, as well as the preference of the facility. Only a limited number of hospitals decide which components to be used based on scientific data. Studies have confirmed that selected novel techniques and components having no basis of scientific justification may pose risk for the life of the patient in the short- and long-term. The objectives of this study are to show how to use quality-control procedures and scientific data for the selection of novel techniques and components and to share, also, recent techniques experienced to minimize the complication risk after surgery.

    Effect of modified Blalock-Taussig shunt anastomosis angle and pulmonary artery diameter on pulmonary flow
    (TURKISH SOC CARDIOLOGY, 2018-01-01) Arnaz, Ahmet; Piskin, Senol; Oguz, Gokece Nur; Yalcinbas, Yusuf; Pekkan, Kerem; Sarioglu, Tayyar
    Objective: This study aimed to identify the best graft-to-pulmonary artery (PA) anastomosis angle measuring pulmonary blood flow, wall shear stress (WSS), and shunt flow. Methods: A tetralogy of Fallot with pulmonary atresia computer model was used to study three different modified Blalock-Taussig shunt (mBTS) anastomosis angle configurations with three different PA diameter configurations. Velocity and WSS were analyzed, and the flow rates at the right PA (RPA) and left PA (LPA) were calculated. Results: A 4-mm and 8-mm diameter of RPA and LPA, respectively with vertical shunt angle produces the highest total flow. In the RPA larger diameter than the LPA configutations, the left-leaning shunt produces the lowest total PA flow whereas in the LPA larger diameter than the RPA configuratios, the right-leaning shunt produces the lowest total PA flow. Therefore, the shunt anastomosis should not be leaned through the narrow side of PA to reach best flow. As the flow inside the shunt increased, WSS also increased due to enhanced velocity gradients. Conclusion: The anastomosis angle between the conduit and PA affects the flow to PA. Vertical anastomosis configurations increase the total PA flow

    Transcatheter Closure of Left Ventricular Pseudoaneurysm After Mitral Valve Replacement
    (ELSEVIER SCIENCE INC, 2020-01-01) Arnaz, Ahmet; Akansel, Serdar; Yalcinbas, Yusuf; Saygili, Arda; Sarioglu, Tayyar
    Left ventricular pseudoaneurysm (LVPA) is a rare but lethal complication of mitral valve replacement (MVR) or myocardial infarction. Early correction is necessary for patients with extensive and expanding LVPA. We report a transcatheter closure of LVPA after MVR. A 63-year-old woman presented with an LVPA 2 months afterMVR. The repeated computed tomographic scan and transthoracic echocardiography showed enhancement of pseudoaneurysm. The LVPA was closed successfully with Amplatzer Vascular Plug using a transcatheter approach. (C) 2020 by The Society of Thoracic Surgeons.

    Pulmonary valve replacement in patients with repaired tetralogy of Fallot: early results for recovery of right ventricular dilatation and QRS duration
    (TUBITAK SCIENTIFIC \& TECHNICAL RESEARCH COUNCIL TURKEY, 2018-01-01) Arnaz, Ahmet; Oktay, Ayla; Akansel, Serdar; Altun, Dilek; Dogan, Abdullah; Serban, Piotr; Saygili, Arda; Yalcinbas, Yusuf; Sarioglu, Ayse; Sarioglu, Tayyar
    Background/aim: Although pulmonary valve replacement (PVR) improves ventricular function and symptoms, the benefit and optimal timing of PVR are controversial. This study aimed to evaluate early response to PVR for right ventricle (RV) dilatation and QRS duration. Materials and methods: Retrospective analysis was performed for 32 patients with repaired tetralogy of Fallot (TOF) between March 2005 and October 2017. The differences between preoperative and postoperative changes in echocardiographic parameters, clinical symptoms, and QRS duration were evaluated. Results: There were no in-hospital or late deaths. Mean age at the time of PVR was 16.57 +/- 7.97 years. The interval between TOF: repair and PVR was 12.99 +/- 7.06 years. Postoperative echocardiographic findings showed significant reduction in indexed RV end-diastolic diameter (RV-EDDI) and the ratio of RV/LV-EDDI (P = 0.001 and P = 0.001, respectively). Higher preoperative RV-EDDI was associated with decreased change in RV-EDDI after PVR (r = 0.63

    Surgical procedures for coronary arteries in pediatric cardiac surgery: Risk factors and outcomes
    (WILEY, 2021-01-01) Sarioglu, Tayyar; Dogan, Abdullah; Yalcinbas, Yusuf; Erek, Ersin; Arnaz, Ahmet; Turkoz, Riza; Oktay, Ayla; Saygili, Arda; Altun, Dilek; Yuksek, Adnan; Boz, Murat; Sarioglu, Ayse
    Background Limited data exist regarding the coronary revascularization procedures needed during the repair of several congenital and pediatric cardiac malformations. We aimed to determine risk factors for in-hospital mortality and long-term outcomes of various pediatric coronary revascularization procedures. Methods We retrospectively reviewed the records of 32 consecutive pediatric patients who underwent coronary revascularization procedures at our institution between May 1995 and June 2020. In-hospital mortality, risk factors, surgical indications, revascularization patency, and mid- and long-term follow-up data were investigated. Patients were categorized into the coronary artery bypass grafting (n = 11) and other coronary artery procedure (n = 21) groups. Results The median age and weight of patients at the time of surgery were 9 months and 4.8 kg, respectively. There were five in-hospital deaths (5/32, 15.6\%). The mortality rates were 27.2\% (3/11) in the coronary artery bypass grafting group and 9.5\% (2/21) in the other coronary artery procedure group (p = .206

    Noninvasive monitoring of central venous oxygen saturation by jugular transcutaneous near-infrared spectroscopy in pediatric patients undergoing congenital cardiac surgery
    (TUBITAK SCIENTIFIC \& TECHNICAL RESEARCH COUNCIL TURKEY, 2020-01-01) Altun, Dilek; Dogan, Abdullah; Arnaz, Ahmet; Yuksek, Adnan; Yalcinbas, Yusuf Kenan; Turkoz, Riza; Sarioglu, Tayyar
    Background and aim: In patients undergoing congenital cardiac surgery, it is crucial to maintain oxygen demand-consumption balance. Central venous oxygen saturation (ScvO(2)) is a useful indicator of oxygen demand and consumption balance which is an invasive method. Near-infrared spectroscopy (NIRS) is a noninvasive, continuous monitoring technique that measures regional tissue oxygenation. NIRS that is placed over the internal jugular vein cutaneous area (NIRSijv) has the potential to show ScvO(2) indirectly. In this study, we aimed to determine the correlation between ScvO(2) with NIRSijv in pediatric patients undergoing congenital cardiac surgery. Materials and methods: Fifty children participated in the study. Four patients were excluded for the inability of internal jugular vein (IJV) catheterization due to technical difficulties. After anesthesia induction, NI RS probes were placed on the IJV site with ultrasound guidance for the measurement of continuous transcutaneous oxygen saturation. The catheter insertion was also done through the IJV from the other side using ultrasound guidance. Cerebral oxygenation monitoring was done using NI RS with a single pediatric probe placed on the right forehead. Values of NIRSijv, cerebral NI RS (NIRSc) and ScvO(2), were recorded at certain times until postoperative 24th hour. Results: Data were collected at 8 different time points. There was a significant correlation between ScvO(2) and NIRSijv in all measurement time points (r = 0.91), (p = 0.001). The mean bias between ScvO(2) and NIRSijv was 2.92\% and the limits of agreement were from 11\% to -5.2\%. There was a moderate correlation between ScvO(2) and NIRSc (r = 0.45), (13= 0.001). The mean bias between ScvO(2) and NIRSc was 2.7\% and the limits of agreement were from +26\% to -20\%. Conclusion: In this study, we found a strong correlation between ScvO(2) and NI RS measurements taken from the internal jugular vein site. Accordingly, continuous noninvasive monitoring with transcutaneous NIRSijv can be an alternative method as a trend monitor for the central venous oxygen saturation in pediatric cardiac patients undergoing congenital cardiac surgery.

    Coronary artery bypass grafting in children
    (WILEY, 2018-01-01) Arnaz, Ahmet; Sarioglu, Tayyar; Yalcinbas, Yusuf; Erek, Ersin; Turkoz, Riza; Oktay, Ayla; Saygili, Arda; Altun, Dilek; Sarioglu, Ayse
    BackgroundWe present our clinical experience with coronary artery bypass grafting (CABG) in children. MethodsTen children who underwent CABG between July 1995 and August 2017 were retrospectively analyzed. Data including congenital cardiac malformations, previous surgical procedures, age and sex, type of coronary complications, ischemic events preceding surgery, and ventricular function before and after CABG were recorded. ResultsThe study population consisted of five males and five females with a median age of 2.5 years (range, 88 days to 15 years). Eight internal mammary arteries (IMAs) and two saphenous veins were used for grafting. Indications for bypass grafting were coronary artery (CA) complications related to the post-arterial switch operation in six, CA complications during the Ross procedure in two, and an iatrogenic CA injury during complete repair of tetralogy of Fallot with abnormal CA, crossing the right ventricular outflow tract in two patients. Six of the grafts were performed as rescue procedures. Three patients died during hospitalization. The mean follow-up time was 6.8 years (range, 3 months to 18 years). Anastomoses were evaluated by coronary angiography in four patients, and were all patent. Echocardiography revealed normal myocardial function in all patients. ConclusionOur study suggests that the IMA should be the graft of choice in children due to its growth potential and long-term patency.

    Why national databases are necessary for pediatric and congenital heart surgery practice?
    (BAYCINAR MEDICAL PUBL-BAYCINAR TIBBI YAYINCILIK, 2019-01-01) Sarioglu, Tayyar; Erek, Ersin; Yalcinbas, Yusuf Kenan
    In international experience, performance improvement, patient safety, and quality assurance are mainly based on database studies in the field of pediatric and congenital cardiac surgery. Data collection and analysis of the databases allow the clinician to identify the complexity, to predict possible risks and complications, and to appropriately evaluate the outcomes and performances. Recently, the Children's Heart Foundation Working Group has developed a database project in Turkey based on the parameters and methodologies of the international databases, namely the Pediatric Heart Surgery National Database. Currently, it is a must for us to put this project into practice to reach the global standards in the pediatric and congenital heart surgery in our country. We believe that all children with congenital heart disease should have an opportunity to benefit from the most recent medical and surgical treatment modalities with the most favorable results.
