Heart (British Cardiac Society), Volume 104, Issue 14, 5 1 2018, Pages 1200-1207 Impact of surgery on presence and dimensions of anatomical isthmuses in tetralogy of Fallot. Kapel GFL, Laranjo S, Blom NA, Hazekamp MG, Schalij MJ, Bartelings MM, Jongbloed MRM, Zeppenfeld K
Objective: In tetralogy of Fallot (TOF), the dominant ventricular tachycardia substrates are slow-conducting anatomical isthmuses. Surgical correction has evolved, which might have influenced isthmus presence and dimensions. Methods: One hundred and forty-two postmortem TOF specimens (84/58 corrected/uncorrected) were studied for isthmus presence. Isthmus 1 is located between the tricuspid annulus and right ventricular (RV) outflow tract (RVOT) patch/RV incision, isthmus 2 between RVOT patch/RV... Abstract

European journal of preventive cardiology, Volume 24, Issue 12, 25 4 2017, Pages 1319-1327 Chance of surgery in adult congenital heart disease. Verheugt CL, Uiterwaal CS, Vaartjes I, van der Velde ET, Zomer AC, Meijboom FJ, Pieper PG, Post MC, Vliegen HW, Hazekamp MG, Grobbee DE, Mulder BJ
Background Young patients with congenital heart disease reaching adulthood face mandatory transition to adult cardiology. Their new cardiologist needs to assess the chances of major future events such as surgery. Using a large national registry, we assessed if patient characteristics at the age of 18 years could predict the chance of congenital heart surgery in adulthood. Design and methods Of 10,300 patients from the CONCOR national registry, we used general patient characteristics at age 18 ye... Abstract

Congenital heart disease, Volume 12, Issue 1, 25 4 2016, Pages 32-39 Surgical outcome in pediatric patients with Ebstein's anomaly: A multicenter, long-term study. Geerdink LM, du Marchie Sarvaas GJ, Kuipers IM, Helbing WA, Delhaas T, Ter Heide H, Rozendaal L, de Korte CL, Singh SK, Ebels T, Hazekamp MG, Haas F, Bogers AJ, Kapusta L
Objective: Surgical outcomes of pediatric patients with Ebstein's anomaly are often described as part of all-age-inclusive series. Our objective is to focus on patients treated surgically in childhood (0-18 y). We study the intended treatment (biventricular or 1.5 ventricle repair or univentricular palliation), freedom from unplanned reoperation and survival of this specific age group, in a nationwide study. Design: Records of all Ebstein's anomaly patients born between 1980 and 2013 w... Abstract

Arrhythmia & electrophysiology review, Volume 5, Issue 2, 1 1 2016, Pages 150-160 Anatomical Substrates and Ablation of Reentrant Atrial and Ventricular Tachycardias in Repaired Congenital Heart Disease. Brouwer C, Hazekamp MG, Zeppenfeld K
Advances in surgical repair techniques for various types of congenital heart disease have improved survival into adulthood over the past decades, thus exposing these patients to a high risk of atrial and ventricular arrhythmias later in life. These arrhythmias arise from complex arrhythmogenic substrates. Substrate formation may depend on both pathological myocardial remodelling and variable anatomical boundaries, determined by the type and timing of prior corrective surgery. Accordingly, arrhyt...

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

Netherlands heart journal : monthly journal of the Netherlands Society of Cardiology and the Netherlands Heart Foundation, Volume 24, Issue 6, 20 3 2016, Pages 400-409 Tailored circulatory intervention in adults with pulmonary hypertension due to congenital heart disease. Couperus LE, Henkens IR, Jongbloed MRM, Hazekamp MG, Schalij MJ, Vliegen HW
Background: Adults with pulmonary hypertension associated with congenital heart disease (PH-CHD) often have residual shunts. Invasive interventions aim to optimise pulmonary flow and prevent right ventricular failure. However, eligibility for procedures strongly depends on the adaptation potential of the pulmonary vasculature and right ventricle to resultant circulatory changes. Current guidelines are not sufficiently applicable to individual patients, who exhibit great diversity and complexity... Abstract

Koolbergen DR, Ahmed Y, Bouma BJ, Scherptong RW, Bruggemans EF, Vliegen HW, Holman ER, Mulder BJ, Hazekamp MG
Objectives: In patients with congenitally corrected transposition of the great arteries (ccTGA) or after atrial (Mustard or Senning) correction for transposition of the great arteries (acTGA), the right ventricle (RV) supports the systemic circulation. The tricuspid valve (TV) (systemic atrioventricular valve) is prone to regurgitation in these patients and this is associated with impending RV failure and decreased survival. This study evaluates mid-term functional improvements, echocardiographi... Abstract

Schneider AW, Hazekamp MG, Versteegh MI, Bruggemans EF, Holman ER, Klautz RJ, Braun J
Objectives: Infective endocarditis of the aortic valve with local aortic root destruction requires radical resection of infected tissues and subsequent reconstruction of periannular structures and the left ventricular outflow tract (LVOT). Homografts or stentless bioprostheses are recommended for use in this specific patient group. The Freestyle stentless bioprosthesis is a porcine aortic root prosthesis, which approaches the surgical versatility of the homograft, but has the advantage of ready... Abstract

Objectives: The Ross-Konno procedure is a last resort for patients with complex multilevel left ventricular outflow tract obstruction (LVOTO) often having other cardiovascular anomalies. It is typically preceded by multiple surgeries. Literature is scarce on long-term follow-up series.

Methods: Between January 1995 and December 2014, 48... Abstract

Nassif M, Lu H, Konings TC, Bouma BJ, Vonk Noordegraaf A, Straver B, Blom NA, Clur SA, Backx AP, Groenink M, Boekholdt SM, Koolbergen DR, Hazekamp MG, Mulder BJ, de Winter RJ
Cardiac platypnoea-orthodeoxia syndrome (POS) is a position-dependent condition of dyspnoea and hypoxaemia due to right-to-left shunting. It often remains unrecognised in clinical practice, possibly because of its complex underlying pathophysiology. We present four consecutive patients with POS and patent foramen ovale (PFO) who underwent a successful percutaneous PFO closure, describe the mechanism of their POS and provide a review of the literature.

European heart journal, Volume 37, Issue 10, 27 4 2015, Pages 829-835 Preoperative thresholds for mid-to-late haemodynamic and clinical outcomes after pulmonary valve replacement in tetralogy of Fallot. Bokma JP, Winter MM, Oosterhof T, Vliegen HW, van Dijk AP, Hazekamp MG, Koolbergen DR, Groenink M, Mulder BJ, Bouma BJ
Aims: The right ventricle (RV) remodels early after pulmonary valve replacement (PVR) in tetralogy of Fallot (TOF) patients. Previously reported preoperative thresholds to achieve early postoperative RV normalization were consistently close to 80 mL/m(2) for end-systolic volume (ESV) and 160 mL/m(2) for end-diastolic volume (EDV). Our objective was to determine whether these thresholds were also associated with mid-to-late RV normalization and clinical events. Methods and results: Out of a multi... Abstract
