    Atrial septal defect closure via mini-thoracotomy in pediatric patients: Postoperative analgesic effect of intercostal nerve block
    (BAYCINAR MEDICAL PUBL-BAYCINAR TIBBI YAYINCILIK, 2020-01-01) Altun, Dilek; Dogan, Abdullah; Amaz, Ahmet; Yuksek, Adnan; Yalcinbas, Yusuf Kenan; Turkoz, Riza; Asar, Sinan; Saneglu, Tayyar
    Background: In this study, we evaluated the efficacy of intercostal nerve block for postoperative pain management in pediatric patients undergoing atrial septal defect closure through a right lateral mini-thoracotomy. Methods: Between January 2016 and January' 2019. a total of 63 pediatric patients (37 males, 26 females: mean age 34.8 +/- 26.8 months

    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.

    Valve-sparing repair with skeletonization of the pulmonary annulus for tetralogy of Fallot
    (WILEY, 2019-01-01) Turkoz, Riza; Dogan, Abdullah; Oktay, Ayla; Saygili, Arda
    Pulmonary valve preservation in tetralogy of Fallot (TOF) repair is one of the most challenging issues. Herein, we describe a novel valve-sparing technique for TOF repair that primarily consists of skeletonization of the anterior part of the pulmonary annulus and gentle dilatation by preserving the pulmonary valve and annulus integrity. With encouraging early results, this technique is suggested to prevent severe pulmonary regurgitation and provide acceptable relief of pulmonary stenosis in patients with TOF.
