The American journal of cardiology, Volume 122, Issue 4, 20 3 2018, Pages 656-662 Development of and Progression of Overt Heart Failure in Nonobstructive Hypertrophic Cardiomyopathy. Hiemstra YL, Debonnaire P, van Zwet EW, Bootsma M, Schalij MJ, Bax JJ, Delgado V, Marsan NA
Only few studies aimed at identifying predictors of heart failure (HF) in hypertrophic cardiomyopathy (HC) patients. Furthermore, serial echocardiographic analyses are lacking in these patients and little is known about the natural progression of left ventricular (LV) abnormalities and their association with HF development. Aim of this study was to assess the prognostic value of LV global longitudinal strain (GLS) and other clinical and echocardiographic characteristics for the development of HF... Abstract

Heart, lung & circulation, Volume 28, Issue 6, 8 2 2018, Pages 893-900 Prognostic Importance of Increased Right Ventricular Afterload in Orthotopic Liver Transplantation Recipients With Endstage Cirrhosis. Couperus LE, Vliegen HW, Sorgdrager BJ, den Dulk AC, Beeres SLMA, Sarton EY, Dubbeld J, Schalij MJ, Jukema JW, van Hoek B, Scherptong RWC
Background: Severely increased right ventricular (RV) afterload is considered a contra-indication for orthotopic liver transplantation (OLT). This study assesses the effects of mildly increased RV afterload on long-term outcome after OLT in relation to RV function. Methods: 139 OLT recipients (53±12years, 76% male) were included. Preoperative RV afterload was assessed invasively or, if not available, echocardiographically and categorised as normal, high-normal (mean pulmonary artery pressure [PA... Abstract

Journal of the American Heart Association, Volume 7, Issue 10, 2 1 2018, Pages e008609 Evaluation of the Impact of a Chronic Total Coronary Occlusion on Ventricular Arrhythmias and Long-Term Mortality in Patients With Ischemic Cardiomyopathy and an Implantable Cardioverter-Defibrillator (the eCTOpy-in-ICD Study). van Dongen IM, Yilmaz D, Elias J, Claessen BEPM, Delewi R, Knops RE, Wilde AAM, van Erven L, Schalij MJ, Henriques JPS
Background: Previous studies report conflicting results about a higher incidence of ventricular arrhythmias in patients with a chronic total coronary occlusion (CTO). We aimed to investigate this association in a large cohort of implantable cardioverter defibrillator patients with long-term follow-up. Methods and results: All consecutive patients from 1992 onwards who underwent implantable cardioverter defibrillator implantation for ischemic cardiomyopathy at the Leiden University Medical Center...

Pediatric cardiology, Volume 39, Issue 4, 16 3 2018, Pages 690-694 Pulmonary Valve Morphology in Patients with Bicuspid Aortic Valves. Koenraadt WMC, Bartelings MM, Gittenberger-de Groot AC, Bökenkamp R, DeRuiter MC, Schalij MJ, Jongbloed MRM
The aortic and pulmonary valve share a common developmental origin from the embryonic arterial trunk. Bicuspid aortic valve is the most common congenital anomaly and can occur isolated as well as in association with other congenital heart disease (CHD). Data on pulmonary valve morphology in these cases are scarce. In this study, we aimed to determine pulmonary valve morphology in hearts with BAV associated with CHD. In 83 post-mortem heart specimens with BAV and associated CHD, pulmonary valve m... Abstract

Heart rhythm, Volume 15, Issue 5, 8 2 2018, Pages 668-676 Fast nonclinical ventricular tachycardia inducible after ablation in patients with structural heart disease: Definition and clinical implications. Watanabe M, de Riva M, Piers SRD, Dekkers OM, Ebert M, Venlet J, Trines SA, Schalij MJ, Pijnappels DA, Zeppenfeld K
Background: Noninducibility of ventricular tachycardia (VT) with an equal or longer cycle length (CL) than that of the clinical VT is considered the minimum ablation endpoint in patients with structural heart disease. Because their clinical relevance remains unclear, fast nonclinical VTs are often not targeted. However, an accepted definition for fast VT is lacking. The shortest possible CL of a monomorphic reentrant VT is determined by the ventricular refractory period (VRP). Objective: The pur... Abstract

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

Eindhoven DC, van Staveren LN, van Erkelens JA, Ikkersheim DE, Cannegieter SC, Umans VAWM, Mosterd A, van Wijngaarden J, Schalij MJ, Borleffs CJW
Introduction: Since health insurance is compulsory in the Netherlands, the centrally registered medical claims data might pose a unique opportunity to evaluate quality of (cardiac) care on a national level without additional collection of data. However, validation of these claims data has not yet been assessed. Design: Retrospective cohort study. Methods: National claims data ('national registry') were compared with data collected by patient records reviews in four representative hospi... Abstract

Circulation. Arrhythmia and electrophysiology, Volume 10, Issue 11, 1 1 2017, Pages e005591 Localized Optogenetic Targeting of Rotors in Atrial Cardiomyocyte Monolayers. Feola I, Volkers L, Majumder R, Teplenin A, Schalij MJ, Panfilov AV, de Vries AAF, Pijnappels DA
Background: Recently, a new ablation strategy for atrial fibrillation has emerged, which involves the identification of rotors (ie, local drivers) followed by the localized targeting of their core region by ablation. However, this concept has been subject to debate because the mode of arrhythmia termination remains poorly understood, as dedicated models and research tools are lacking. We took a unique optogenetic approach to induce and locally target a rotor in atrial monolayers. Methods and res... Abstract
