(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.
Ebstein's Anomaly
(GAZI UNIV, FAC MED, 2018-01-01) Arnaz, Ahmet; Dogan, Abdullah; Oktay, Ayla; Yalcinbas, Yusuf; Turkoz, Riza; Saygili, Arda; Sarioglu, Ayse; Sarioglu, Tayyar
Objectives: In this study, it is aimed to evaluate the operations performed for Ebstein `s anomaly retrospectively. Study design: Between July 2003 and February 2018, the medical records of 13 patients who were operated on with the diagnosis of Ebstein's anomaly were reviewed retrospectively according to the clinical symptoms, surgical procedure, and postoperative follow-up. Results: Of the thirteen patients, 46.2\% (n = 6) were female and 53.8\% (n = 7) were male. The mean age of the cases is 13,15 +/- 11,07 years (2-31 years). Preoperative echocardiographic evaluations revealed severe tricuspid regurgitation in 92.3\% (n = 12) of the patients. In these patients, tricuspid valve replacement was performed in 4, tricuspid valve plasty in 5, Cone reconstruction in 2, and cava-pulmonary shunt with tricuspid valve plasty in 2 were performed. Patients were followed for an average of 6.31 +/- 3.40 (1-14 years). Atrial septal defect closure in 53.8\% (n = 7) patients and mitral valve replacement in 7.7\% (n = 1) patients were performed due to additional anomalies. Atrial fibrillation/flutter was present in 23.1\% of the patients and ablation procedure was applied to these three patients. Conclusion: Long-term clinical follow-up is required for the signs and symptoms of heart failure, arrhythmia, cyanosis and other related findings both in operated and non-operated patients with Ebstein's anomaly.
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
