(SPRINGER INDIA, 2020-01-01) Suzan, Dilek; Aydin, Selim; Demir, Ibrahim Halil; Erek, Ersin
Association of interrupted aortic arch with aortic atresia as a variant of hypoplastic left heart syndrome (HLHS) is extremely rare and could not be compatible with life without a reliable source for cerebral and coronary blood flow. The patient with a large collateral artery between the descending aorta and the right subclavian artery is presented.

(WILEY, 2021-01-01) Temur, Bahar; Aydin, Selim; Suzan, Dilek; Kirat, Baris; Demir, Ibrahim Halil; Erek, Ersin
Background Transannular patch, which results in pulmonary insufficiency (PI), is usually required during repair of tetralogy of fallot (TOF). In this study, we compared three types of pulmonary valve reconstruction techniques during transannular repair of TOF. Methods Between February 2014 and January 2018, 50 patients with TOF underwent primary repair with transannular patch. These patients were divided into three groups. In Group 1, (n = 15), a single gluteraldehyde-treated autologous pericardial patch (standard method) was reconstructed as monocusp. In Group 2, (n = 16) Nunn's bileaflet pulmonary valve reconstruction technique was used with pericardial patch. In Group 3, (n = 19), Nunn's bileaflet technique was performed with expanded polytetrafluoroethylene membrane. The outcomes of the patients and early and midterm competency of the pulmonary valves were analyzed. Results These techniques were significantly effective in early postoperative period. Freedom from moderate to severe PI were 73.3\%

Outcomes of hybrid and Norwood Stage I procedures for the treatment of hypoplastic left heart syndrome and its variants
(BAYCINAR MEDICAL PUBL-BAYCINAR TIBBI YAYINCILIK, 2020-01-01) Erek, Ersin; Aydin, Selim; Temur, Bahar; Onalan, Mehmet Akif; Suzan, Dilek; lyigun, Muzeyyen; Demi, lBrahim Halil; Odemis, Ender
Background: In this study. we present the outcomes of hybrid and Norwood Stage I procedures for the treatment of hypoplastic left heart syndrome and its variants. Methods: In this study, a total of 97 pediatric patients who were operated due to hypoplastic left heart syndrome and its variants between March 2011 and October 2018 were retrospectively analyzed. Thirty-two of the patients (28 males, 4 females: median age 5 days: range, 1 to 25 days) underwent Norwood Stage I operation (Group N). while the remaining 65 patients (44 males, 21 females: median age 6 days: range, 1 to 55 days) underwent a hybrid procedure (Group H). Both treatment strategies were compared. Results: The median body weight in Group H was significantly lower and the number of patients with a low birth weight (<2,500 g) was significantly higher than Group N (p=0.002 and 0.004. respectively). The postoperative early mortality rate was similar between the groups. Univariate and multivariate analyses revealed that the need for preoperative mechanical ventilation was a significant factor for mortality (p=0.004 and 0.003, respectively). Syndromic appearance was also a significant factor the multivariate analysis (p=0.03). There was a statistically significant difference between the groups in terms of the inter-stage mortality rates (p=0.0045). Second-stage procedure was performed in 32 patients. The early mortality rate after the Glenn operation was 7.6\%. Six patients died after comprehensive Stage II operation. Five patients underwent biventricular repair and 8 patients had third-stage fenestrated extracardiac Fontan operation (Group N, n=7 and Group H. n=1). The Kaplan-Meier survival curve demonstrated that Group N had a higher survival rate at both one and five years than Group II. although the difference was not statistically significant (p=0.15). Subgroup analysis showed that the Norwood procedure with Sano modification had the highest survival rate with 40\% at five years. Conclusion: Our study results show that patients undergoing the Norwood procedure have a more uneventful course of inter-stage period and Stage II and III. despite drawbacks early after Stage I procedure. Based on our experiences, we recommend performing the hybrid intervention in patients with a poor clinical condition and a body weight of <2.500 g.

Background: In this study, we analyzed the impact of pulmonary valve-sparing techniques on early and midterm postoperative results of tetralogy of Fallot repair. Methods: A total of 64 patients diagnosed with tetralogy of Fallot, who underwent total correction operation by the same surgeon between November 2010 and September 2015 were included in this retrospective study. Mean age of the patients was 20.0 +/- 14.2 months (5.5-96 months). Forty patients (62.5\%) were male. Thirty two of the patients (50\%) were under one year of age. Pulmonary valve-sparing techniques were performed in 29 patients (Group 2), while transannular patch was applied in the remaining 35 patients (Group 1). Pericardial monocusp valve was constructed in 15 patients in Group 1. In Group 2, pulmonary valve-sparing techniques were transatrial repair in nine patients

(SAGE PUBLICATIONS INC, 2020-01-01) Temur, Bahar; Davutoglu, Arda; Dogruoz, Alper; Aydin, Selim; Suzan, Dilek; Kirat, Baris; Odemis, Ender; Erek, Ersin
Background: Adhesions due to previous surgeries and some anatomical difficulties may make resternotomy dangerous in children. Femoral vessels are usually small and may not be suitable for cannulation. The aim of this report is to describe our experience with cervical cannulation during risky resternotomy in children. Methods: Between January 2014 and January 2018, cervical cannulation was performed in eight pediatric patients during sternal reentry. Their ages were between 3 months and 17 years (mean: 5.4 years). Three patients underwent stage III extracardiac Fontan operation with the diagnosis of hypoplastic left heart syndrome. Three patients had supravalvular aortic and/or pulmonary stenosis after previous arterial switch operation. One patient had proximal aortic arch stenosis and subvalvular aortic stenosis after interrupted aortic arch repair. The last patient had aortic root pseudoaneurysm and aortic insufficiency due to endocarditis. Through a separate cervical incision, a polytetrafluoroethylene graft was anastomosed to the common carotid artery and the arterial cannula was inserted into the graft. Antegrade selective cerebral perfusion (ASCP) was used in two patients. Results: During resternotomies, no major injury or bleeding occurred. Three-month-old patient who had previous interrupted aortic arch repair died despite extracorporeal membrane oxygenation support due to sepsis and multi-organ failure. Median intensive care unit stay and hospital stay were 3 days (1-40 days) and 17 days (7-60 days), respectively. Mean follow-up was 17.9 +/- 15.8 months. All patients were in good clinical condition. Conclusions: Cervical cannulation may be a useful and safe technique during high-risk resternotomy in children. This technique may also simplify the performance of ASCP if necessary.
