Protopapas EM, Anderson RH, Backer CL, Fragata J, Hakim N, Vida VL, Sarris GE, European Congenital Heart Surgeons Association-World Society for Pediatric and Congenital Heart Surgery (ECHSA-WSPCHS) Study Group, Barron DJ, Berggren H, Hazekamp MG, Ilyin V, Kornoukhov OJ, Kostolny M, Lazarov S, Lo Rito M, Monge MC, Mykychak Y, Nosal M, Prêtre R, Polimenakos AC, Sojak V, Stellin G, Veshti A, Yemets I
Aorto-ventricular tunnel (AoVT), a rare congenital anomaly, is a channel originating in the ascending aorta just above the sinotubular junction and leading to the cavity of the left ventricle (AoLVT), or, rarely, the right (AoRVT). This study reviews our collective 30-year experience with the surgical treatment of AoVT. Data were submitted by 15 participating centers on 42 patients who underwent correction of AoVT between 1987 and 2018. Of these, 36 had AoLVT, and 6 AoRVT. The tunnel originated... Abstract

European journal of cardio-thoracic surgery : official journal of the European Association for Cardio-thoracic Surgery, Volume 55, Issue 2, 1 1 2019, Pages 331-337 Aortic coarctation repair through left thoracotomy: results in the modern era. Farag ES, Kluin J, de Heer F, Ahmed Y, Sojak V, Koolbergen DR, Blom NA, de Mol BAJM, Ten Harkel ADJ, Hazekamp MG
Objectives: Surgical repair of coarctation of the aorta (CoA) is often possible through left thoracotomy and without the use of cardiopulmonary bypass. Recent studies reporting the outcome after CoA repair through left thoracotomy are limited. Therefore, the aim of this study is to evaluate the results of CoA repair through left thoracotomy in children who were operated on in our centre over the past 21 years. Methods: From January 1995 to December 2016, 292 patients younger than 18 years underw... Abstract

World journal for pediatric & congenital heart surgery, Volume 9, Issue 6, 22 4 2018, Pages 638-644 Long-Term Outcome of Direct Relief of Subaortic Stenosis in Single Ventricle Patients. Rijnberg FM, Sojak V, Blom NA, Hazekamp MG
Background: Single ventricle patients with unrestrictive pulmonary blood flow and (potential) subaortic stenosis are challenging to manage and optimal surgical strategy is unknown. Direct relief of subaortic stenosis by enlargement of the ventricular septal defect and/or subaortic chamber has generally been replaced by a Damus-Kaye-Stansel or Norwood procedure due to concerns of iatrogenic heart block, reobstruction, or ventricular dysfunction. Studies reporting long-term outcome after the direc... Abstract

Seminars in thoracic and cardiovascular surgery. Pediatric cardiac surgery annual, Volume 21, 1 1 2018, Pages 58-63 Nikaidoh vs Réparation à l'Etage Ventriculaire vs Rastelli. Hazekamp MG, Nevvazhay T, Sojak V
This review describes the different surgical options for transposition of the great arteries, ventricular septal defect (VSD), and left ventricular outflow tract obstruction. When the pulmonary valve can be used, an arterial switch operation with VSD closure and resection of pulmonary stenosis may be possible. This is not the scope of our review: we focus on the Rastelli, REV (Réparation à l'Etage Ventriculaire), and Nikaidoh techniques, and we also describe the "en bloc rotation"... Abstract

European journal of cardio-thoracic surgery : official journal of the European Association for Cardio-thoracic Surgery, Volume 49, Issue 5, 1 1 2016, Pages e91-6 Reoperation for right ventricular outflow tract obstruction after arterial switch operation for transposition of the great arteries and aortic arch obstruction. Bokenkamp R, Aguilar E, van der Palen RL, Sojak V, Bruggemans EF, Hruda J, Kuipers IM, Hazekamp MG
Objectives: Right ventricular outflow tract obstruction (RVOTO) is one of the reasons for late reinterventions after repair of transposition of the great arteries (TGA) with aortic arch obstruction (AAO). The aim of the present study was to identify predictors of reoperation for RVOTO in patients who underwent arterial switch operation (ASO) and arch repair for TGA or Taussig-Bing anomaly with AAO. Methods: Between 1977 and 2015, 45 patients [TGA/intact ventricular septum (IVS) 5, TGA/ventricula... Abstract

Sojak V, Kooij M, Yazdanbakhsh A, Koolbergen DR, Bruggemans EF, Hazekamp MG
Objectives: To evaluate our experience with patients reoperated after primary repair of atrioventricular septal defect (AVSD) and identify predictors of poor outcome. Methods: Between 1976 and 2014, 69 patients were reoperated after primary repair of partial (n = 28), intermediate (n = 15) or complete (n = 26) AVSD. Results: Median age at first reoperation was 62.4 (range, 1.6-845) months, median interval to first reoperation was 22.3 (range, 0.2-598) months. Main indications for first reoperati... Abstract

Schoormans D, Smets EM, Zwart R, Sprangers MA, Veelenturg TH, de Mol BA, Hazekamp MG, Koolbergen DR, Sojak V, Bouma BJ, Groenink M, Boekholdt MS, Backx AP, Mulder BJ
Background: Patient satisfaction with care has received little attention within the field of congenital heart disease. Our objective was to examine patient satisfaction with the care received when undergoing open-heart surgery in order to identify the best and worst aspects of peri-operative care. Moreover, we examined whether having contact with a specialised nurse in addition to usual care is associated with higher patient satisfaction levels. Methods: Patient satisfaction was measured by the... Abstract
