Segment Length in Cine Strain Analysis Predicts Cardiac Resynchronization Therapy Outcome Beyond Current Guidelines

Alwin Zweerink, Daniel J. Friedman, Igor Klem, Peter M. van de Ven et autres

Background: Patients with a class I recommendation for cardiac resynchronization therapy (CRT) are likely to benefit, but the effect of CRT in class II patients is more heterogeneous and additional selection parameters are needed in this group. The recently validated segment length …

Comparison between cardiac magnetic resonance stress T1 mapping and [15O]H2O positron emission tomography in patients with suspected obstructive coronary artery disease

Henk Everaars, Pepijn A. van Diemen, P. Stefan Biesbroek, Luuk H G A Hopman et autres

AIMS: To compare cardiac magnetic resonance (CMR) measurement of T1 reactivity (ΔT1) with [15O]H2O positron emission tomography (PET) measurements of quantitative myocardial perfusion. METHODS AND RESULTS: Forty-three patients with suspected obstructed coronary artery disease underwent [15O]H2O PET and CMR at 1.5-T, including …

Myocardial adaptation after surgical therapy differs for aortic valve stenosis and hypertrophic obstructive cardiomyopathy

Rahana Y. Parbhudayal, Ahmet Güçlü, Alwin Zweerink, P. Stefan Biesbroek et autres

Surgical therapies in aortic valve stenosis (AVS) and hypertrophic obstructive cardiomyopathy (HOCM) aim to relief intraventricular pressure overload and improve clinical outcome. It is currently unknown to what extent myocardial adaptation concurs with restoration of intraventricular pressures, and whether this is similar …

Inflammation and Cardiovascular Disease: Evaluation by CMR and Histology

P. Stefan Biesbroek

Size Matters

Alwin Zweerink, Daniel J. Friedman, Igor Klem, Peter M. van de Ven et autres

BACKGROUND: In patients with left bundle branch block (LBBB), QRS duration (QRSd) depends on left ventricular (LV) dimension. Previously, we demonstrated that normalizing QRSd to LV dimension, to adjust for variations in LV size, improved prediction of hemodynamic response to cardiac resynchronization …

P5735Normalization of QRS duration to left ventricular dimension improves patient selection for cardiac resynchronization therapy

Alwin Zweerink, Daniel J. Friedman, Igor Klem, Peter M. van de Ven et autres

Background: In patients with left bundle branch block (LBBB), QRS duration (QRSd) is dependent on both myocardial conduction velocity and conduction path length. Although left ventricular (LV) dilation causes QRSd lengthening which is expected to result in more cardiac resynchronization therapy (CRT) …

Additional diagnostic value of CMR to the European Society of Cardiology (ESC) position statement criteria in a large clinical population of patients with suspected myocarditis

P. Stefan Biesbroek, Alexander Hirsch, Alwin Zweerink, Peter M. van de Ven et autres

Aims: To determine the diagnostic yield of tissue characterization by cardiovascular magnetic resonance (CMR) in a large clinical population of patients with suspected acute myocarditis (AM) and to establish its diagnostic value within the 2013 European Society of Cardiology position statement criteria …

The influence of microvascular injury on native T1 and T2* relaxation values after acute myocardial infarction: implications for non-contrast-enhanced infarct assessment

Lourens Robbers, Robin Nijveldt, Aernout M. Beek, Paul F. Teunissen et autres

OBJECTIVES: Native T1 mapping and late gadolinium enhancement (LGE) imaging offer detailed characterisation of the myocardium after acute myocardial infarction (AMI). We evaluated the effects of microvascular injury (MVI) and intramyocardial haemorrhage on local T1 and T2* values in patients with a …

P866Effects of successful percutaneous coronary intervention of chronic total occlusions on myocardial perfusion and left ventricular function

Stefan Schumacher, Wijnand J. Stuijfzand, P. Stefan Biesbroek, P. G. Raijmakers et autres

Background: Chronic total occlusions (CTO) are observed in up to 30% of patients with known or suspected coronary artery disease. Percutaneous coronary intervention (PCI) of CTO is technically challenging and its salutary effects are questioned. Purpose: The aim of the present study …
