Rademaker R, Kimura Y, de Riva Silva M, Beukers HC, Piers SRD, Wijnmaalen AP, Dekkers OM, Zeppenfeld K
Aims: Patients with ischaemic cardiomyopathy (ICM) referred for catheter ablation of ventricular tachycardia (VT) are at risk for end-stage heart failure (HF) due to adverse remodelling. Local unipolar voltages (UV) decrease with loss of viable myocardium. A UV parameter reflecting global viable myocardium may predict prognosis. We evaluate if a newly proposed parameter, area-weighted unipolar voltage (awUV), can predict HF-related outcomes [HFO; HF death/left ventricular (LV) assist device/hear... Abstract

Netherlands heart journal : monthly journal of the Netherlands Society of Cardiology and the Netherlands Heart Foundation, Volume 31, Issue 7-8, 28 4 2023, Pages 315-323 The arrhythmogenic cardiomyopathy phenotype associated with PKP2 c.1211dup variant. Bos TA, Piers SRD, Wessels MW, Houweling AC, Bökenkamp R, Bootsma M, Bosman LP, Evertz R, Hellebrekers DMEI, Hoedemaekers YM, Knijnenburg J, Lekanne Deprez R, van Mil AM, Te Riele ASJM, van Slegtenhorst MA, Wilde AAM, Yap SC, Dooijes D, Koopmann TT, van Tintelen JP, Barge-Schaapveld DQCM, European Reference Network for rare, low prevalence and complex diseases of the heart: ERN GUARD-Heart
Background: The arrhythmogenic cardiomyopathy (ACM) phenotype, with life-threatening ventricular arrhythmias and heart failure, varies according to genetic aetiology. We aimed to characterise the phenotype associated with the variant c.1211dup (p.Val406Serfs*4) in the plakophilin‑2 gene (PKP2) and compare it with previously reported Dutch PKP2 founder variants. Methods: Clinical data were collected retrospectively from medical records of 106 PKP2 c.1211dup heterozygous carriers. Using data from... Abstract

Europace : European pacing, arrhythmias, and cardiac electrophysiology : journal of the working groups on cardiac pacing, arrhythmias, and cardiac cellular electrophysiology of the European Society of Cardiology, Volume 25, Issue 3, 1 1 2023, Pages 1035-1040 Unipolar voltage mapping in right ventricular cardiomyopathy: pitfalls, solutions and advantages. Hoogendoorn JC, Venlet J, de Riva M, Wijnmaalen AP, Piers SRD, Zeppenfeld K
Aims: Endocardial unipolar and bipolar voltage mapping (UVM/BVM) of the right ventricle (RV) are used for transmural substrate delineation. However, far-field electrograms (EGMs) and EGM changes due to injury current may influence automatically generated UVM. Epicardial BVM is considered less accurate due to the impact of fat thickness (FT). Data on epicardial UVM are sparse. The aim of the study is two-fold: to assess the influence of the manually corrected window-of-interest on UVM and the pot... Abstract

Europace : European pacing, arrhythmias, and cardiac electrophysiology : journal of the working groups on cardiac pacing, arrhythmias, and cardiac cellular electrophysiology of the European Society of Cardiology, Volume 22, Issue 9, 1 1 2020, Pages 1376-1383 The harm of delayed diagnosis of arrhythmogenic cardiac sarcoidosis: a case series. Hoogendoorn JC, Ninaber MK, Piers SRD, de Riva M, Grauss RW, Bogun FM, Zeppenfeld K
Aims: Cardiac sarcoidosis (CS) is a known cause of ventricular tachycardia (VT). However, an arrhythmogenic presentation may not prompt immediate comprehensive evaluation. We aimed to assess the diagnostic and disease course of patients with arrhythmogenic cardiac sarcoidosis (ACS). Methods and results: From the Leiden VT-ablation-registry, consecutive patients with CS as underlying aetiology were retrospectively included. Data on clinical presentation, time-to-diagnosis, cardiac function, and c... Abstract

JACC. Clinical electrophysiology, Volume 6, Issue 9, 12 2 2020, Pages 1073-1085 RV Tissue Heterogeneity on CT: A Novel Tool to Identify the VT Substrate in ARVC. Venlet J, Tao Q, de Graaf MA, Glashan CA, de Riva Silva M, van der Geest RJ, Scholte AJ, Piers SRD, Zeppenfeld K
Objectives: This study sought to evaluate whether right ventricular (RV) tissue heterogeneity on computed tomography (CT): 1) is associated with conduction delay in arrhythmogenic right ventricular cardiomyopathy (ARVC); and 2) distinguishes patients with ARVC from those with exercise-induced arrhythmogenic remodeling (EIAR) and control individuals. Background: ARVC is characterized by fibrofatty replacement, related to conduction delay and ventricular tachycardias. Distinguishing ARVC from acqu... Abstract

JACC. Clinical electrophysiology, Volume 6, Issue 6, 29 5 2020, Pages 696-707 Electroanatomical Voltage Mapping to Distinguish Right-Sided Cardiac Sarcoidosis From Arrhythmogenic Right Ventricular Cardiomyopathy. Hoogendoorn JC, Sramko M, Venlet J, Siontis KC, Kumar S, Singh R, Nakajima I, Piers SRD, de Riva Silva M, Glashan CA, Crawford T, Tedrow UB, Stevenson WG, Bogun F, Zeppenfeld K
Objectives: This study sought to investigate the value of electroanatomical voltage mapping (EAVM) to distinguish cardiac sarcoidosis (CS) from arrhythmogenic right ventricular cardiomyopathy (ARVC) in patients with ventricular tachycardia from the right ventricle (RV). Background: CS can mimic ARVC. Because scar in ARVC is predominantly subepicardial, this study hypothesized that the relative sizes of endocardial low bipolar voltage (BV) to low unipolar voltage (UV) areas may distinguish CS fro...

JACC. Clinical electrophysiology, Volume 5, Issue 4, 27 4 2019, Pages 480-489 Entropy as a Novel Measure of Myocardial Tissue Heterogeneity for Prediction of Ventricular Arrhythmias and Mortality in Post-Infarct Patients. Androulakis AFA, Zeppenfeld K, Paiman EHM, Piers SRD, Wijnmaalen AP, Siebelink HJ, Sramko M, Lamb HJ, van der Geest RJ, de Riva M, Tao Q
Objectives: This study proposed entropy as a new late gadolinium enhanced cardiac magnetic resonance-derived parameter to evaluate tissue inhomogeneity, independent of signal intensity thresholds. This study hypothesized that entropy within the scar is associated with ventricular arrhythmias (VAs), whereas entropy of the entire left ventricular (LV) myocardium is associated with mortality. Background: In patients after myocardial infarction, the heterogeneity of fibrosis determines the substrate... Abstract

European heart journal, Volume 39, Issue 31, 1 1 2018, Pages 2867-2875 Whole human heart histology to validate electroanatomical voltage mapping in patients with non-ischaemic cardiomyopathy and ventricular tachycardia. Glashan CA, Androulakis AFA, Tao Q, Glashan RN, Wisse LJ, Ebert M, de Ruiter MC, van Meer BJ, Brouwer C, Dekkers OM, Pijnappels DA, de Bakker JMT, de Riva M, Piers SRD, Zeppenfeld K
Aims: Electroanatomical voltage mapping (EAVM) is an important diagnostic tool for fibrosis identification and risk stratification in non-ischaemic cardiomyopathy (NICM); currently, distinct cut-offs are applied. We aimed to evaluate the performance of EAVM to detect fibrosis by integration with whole heart histology and to identify the fibrosis pattern in NICM patients with ventricular tachycardias (VTs). Methods and results: Eight patients with NICM and VT underwent EAVM prior to death or hear... 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

Venlet J, Piers SRD, Kapel GFL, de Riva M, Pauli PFG, van der Geest RJ, Zeppenfeld K
Background: Low endocardial unipolar voltage (UV) at sites with normal bipolar voltage (BV) may indicate epicardial scar. Currently applied UV cutoff values are based on studies that lacked epicardial fat information. This study aimed to define endocardial UV cutoff values using computed tomography-derived fat information and to analyze their clinical value for right ventricular substrate delineation. Methods and results: Thirty-three patients (50±14 years; 79% men) underwent combined endocardia... Abstract
