The American journal of cardiology, Volume 95, Issue 1, 1 1 2005, Pages 140-142 Frequency of left ventricular dyssynchrony in patients with heart failure and a narrow QRS complex. Bleeker GB, Schalij MJ, Molhoek SG, Holman ER, Verwey HF, Steendijk P, van der Wall EE, Bax JJ
Cardiac resynchronization therapy (CRT) is considered a major advance in the treatment of patients with heart failure. The presence of left ventricular (LV) dyssynchrony seems mandatory for a positive response to CRT. Currently, only patients with wide QRS complexes are considered for CRT, although patients with narrow QRS complexes may also have LV dyssynchrony. In the present study, the incidence of LV dyssynchrony was prospectively evaluated in 64 patients with heart failure and narrow QRS co... Abstract

European journal of epidemiology, Volume 20, Issue 6, 1 1 2005, Pages 549-557 CONCOR, an initiative towards a national registry and DNA-bank of patients with congenital heart disease in the Netherlands: rationale, design, and first results. van der Velde ET, Vriend JW, Mannens MM, Uiterwaal CS, Brand R, Mulder BJ
Introduction: Survival of patients with congenital heart disease has dramatically improved after surgical repair became available 40 years ago. Instead of a mortality of 85% during childhood following the natural course, over 85% of these infants are now expected to reach adulthood. However, data on long-term outcome is scarce due to the lack of large, national registries. Moreover, little is known about the genetic basis of congenital heart defects. In 2000, the Interuniversity Cardiology Insti... Abstract

Cell biochemistry and biophysics, Volume 43, Issue 1, 1 1 2005, Pages 45-52 Angiotensin AT2 receptor deficiency after myocardial infarction: its effects on cardiac function and fibrosis depend on the stimulus. Tschöpe C, Westermann D, Dhayat N, Dhayat S, Altmann C, Steendijk P, Schultheiss HP, Walther T
Hearts of normotensive angiotensin II type 2 receptor (AT2)-deficient mice do not develop fibrosis after angiotensin II-induced chronic hypertension. Thus, the goal of our study was to clarify whether AT2 knockouts (KOs) are also characterized by altered left ventricular (LV) function and modified remodeling of the extracellular matrix (ECM) after induction of myocardial infarction (MI). MI was induced in 5-mo-old female AT2-deficient mice and controls by occlusion of the left coronary artery. T... Abstract

Journal of cardiovascular magnetic resonance : official journal of the Society for Cardiovascular Magnetic Resonance, Volume 7, Issue 2, 1 1 2005, Pages 383-389 Disparity between dobutamine stress and physical exercise magnetic resonance imaging in patients with an intra-atrial correction for transposition of the great arteries. Oosterhof T, Tulevski II, Roest AA, Steendijk P, Vliegen HW, van der Wall EE, de Roos A, Tijssen JG, Mulder BJ
Background: In patients with an intra-atrial correction for transposition of the great arteries (TGA) an abnormal response to stress testing is common. However, hemodynamic responses may vary substantially when different stress tests are used. We compared the hemodynamic response to dobutamine stress with the response to physical exercise in patients and controls. Methods: Thirty-nine patients and 25 age/sex-matched control subjects underwent either dobutamine stress (15 microg/kg/min) or submax... Abstract

European journal of echocardiography : the journal of the Working Group on Echocardiography of the European Society of Cardiology, Volume 6, Issue 4, 20 3 2004, Pages 297-300 Underestimation of severity of mitral regurgitation with varying hemodynamics. Scholte AJ, Holman ER, Haverkamp MC, Poldermans D, van der Wall EE, Dion RA, Bax JJ
Transesophageal echocardiography (TEE) is a valuable technique to assess mitral valve anatomy and the mechanism of mitral regurgitation (MR). We present the case of a 35-year-old woman with severe MR due to restrictive motion of the posterior mitral leaflet, who was referred for mitral annuloplasty. Under physiologic circumstances, a severe (grade 3+) MR was present, whereas in the operating room during general anesthesia, the MR had disappeared almost completely. The downgrading of MR due to ge... Abstract

European journal of cardio-thoracic surgery : official journal of the European Association for Cardio-thoracic Surgery, Volume 27, Issue 3, 19 3 2004, Pages 462-6; discussion 467 Accurate quantitation of regurgitant volume with MRI in patients selected for mitral valve repair. Westenberg JJ, Doornbos J, Versteegh MI, Bax JJ, van der Geest RJ, de Roos A, Dion RA, Reiber JH
Objective: Echocardiography, the currently preferred diagnostic approach for mitral valve regurgitation, cannot accurately quantify the amount of regurgitation. Flow quantification with MRI is possible, but the conventional method (1-directional velocity-encoding) acquires the flow at a fixed location during the cardiac cycle, which is not necessarily the location of the mitral valve during the whole cycle. In this study, the exact flow through the mitral valve was quantified with a 3-directiona... Abstract
