Hazekamp MG, Kurvers MM, Schoof PH, Vliegen HW, Mulder BM, Roest AA, Ottenkamp J, Dion RA
Objectives: To analyze the results of pulmonary valve insertion late after initial repair of Fallot's tetralogy. Pulmonary insufficiency (PI) after correction of Fallot's tetralogy is usually well tolerated in the short term, but is associated with symptomatic right ventricular dilatation and an increased risk of ventricular arrhythmias over longer periods of time. Methods: From 1993 to July 2000, 51 patients were reoperated for PI at a mean age of 25.7+/-11.9 years. The mean age at in... Abstract

Bax JJ, Lamb H, Dibbets P, Pelikan H, Boersma E, Viergever EP, Germano G, Vliegen HW, de Roos A, Pauwels EK, Van der Wall EE
To perform a head-to-head comparison between magnetic resonance imaging (MRI) and gated single-photon emission computed tomography (SPECT) for the evaluation of left ventricular (LV) function (LV ejection fraction [LVEF], LV volumes, and regional wall motion) in patients with ischemic cardiomyopathy, we studied 22 patients with chronic coronary artery disease and LV dysfunction. Multislice, multiphase echoplanar MRI was performed with Philips Gyroscan ACS-NT15. Image analysis was performed using... Abstract

International journal of cardiac imaging, Volume 16, Issue 1, 1 1 2000, Pages 35-41 Imaging of an aneurysm of the sinus of Valsalva with transesophageal echocardiography, contrast angiography and MRI. Baur LH, Vliegen HW, van der Wall EE, Hazekamp M, Bootsma M, de Roos A, Bruschke AV
A sinus of Valsalva aneurysm is an uncommon congenital defect, which requires appropriate diagnosis with either echocardiography, magnetic resonance imaging or contrast angiography. Treatment consists of aortic valve repair. We describe a young woman with an aneurysm of the non-coronary sinus of Valsalva, an atrial septal defect and pulmonary insufficiency. The different imaging techniques and possibilities of surgical correction are described. Abstract

Magnetic resonance (MR) angiography and flow mapping have the potential to become a major noninvasive diagnostic tool for the assessment of coronary artery bypass graft morphology and function. Several MR sequences, such as conventional non-respiratory compensated methods, and phase contrast cine flow sequences have been reported for the evaluation of bypass graft patency. However the visualization of different graft segments and the detection of graft stenosis remains difficult. Recent advances... Abstract

International journal of cardiac imaging, Volume 15, Issue 3, 1 1 1999, Pages 253-8; discussion 259 Diagnosis and management of anomalous origin of the right coronary artery from the left coronary sinus. Bekedam MA, Vliegen HW, Doornbos J, Jukema JW, de Roos A, van der Wall EE
The anomalous origin of the right coronary artery (RCA) from the left sinus of Valsalva coursing between the aorta and the pulmonary artery or right ventricular outflow tract, is considered a potentially fatal abnormality which may require surgery. However, diagnosing the correct course with coronary arteriography may be difficult. Fast gradient echo magnetic resonance (MR) imaging can be helpful to identify and confirm the course of aberrant coronary arteries and their relationship to the surro... Abstract

Aim: Description of embolization as a treatment for bleeding bronchopulmonary collaterals in congenital heart disease. Methods: After palliative corrective surgery of Tetralogy of Fallot with pulmonary atresia, haemoptysis due to ruptured bronchopulmonary collaterals is a well known complication. We describe a 31 year old patient with haemoptysis after incomplete correction because of Tetralogy of Fallot with pulmonary atresia. Because supportive treatment failed, the bleeding site was localized... Abstract

Pluim BM, Lamb HJ, Kayser HW, Leujes F, Beyerbacht HP, Zwinderman AH, van der Laarse A, Vliegen HW, de Roos A, van der Wall EE
Background: The question of whether training-induced left ventricular hypertrophy in athletes is a physiological rather than a pathophysiological phenomenon remains unresolved. The purpose of the present study was to detect any abnormalities in cardiac function in hypertrophic hearts of elite cyclists and to examine the response of myocardial high-energy phosphate metabolism to high workloads induced by atropine-dobutamine stress. Methods and results: We studied 21 elite cyclists and 12 healthy... Abstract

Aim: The purpose of the study was to compare the accuracy of M-mode echocardiography and two different two-dimensional echocardiographic approaches in the assessment of left ventricular mass and volumes in endurance-trained and strength-trained athletes, using magnetic resonance imaging as reference standard.

Background: The cardiovascular applications of magnetic resonance (MR) techniques in coronary artery disease have increased considerably in recent years. Technical advantages of MR imaging are the excellent spatial resolution, the characterization of myocardial tissue, and the potential for three-dimensional imaging. These characteristics allow the accurate assessment of left ventricular mass and volume, the differentiation of infarcted from normal tissue, and the determination of systolic wall... Abstract

The American journal of cardiology, Volume 79, Issue 6, 1 1 1997, Pages 773-776 Value of fast gradient echo magnetic resonance angiography as an adjunct to coronary arteriography in detecting and confirming the course of clinically significant coronary artery anomalies. Vliegen HW, Doornbos J, de Roos A, Jukema JW, Bekedam MA, van der Wall EE
We investigated the additional value of magnetic resonance (MR) angiography in 12 patients with clinically significant coronary anomalies. In 5 patients, the referring cardiologist requested additional evaluation because coronary arteriography was inconclusive about the course of the anomaly. For comparison, 7 patients with known anomalous coronary arteries were collected from our database. In these patients, there had been no doubt about the course of the anomalous coronary arteries. MR angiogr... Abstract

We investigated whether left ventricular hypertrophy in elite cyclists is associated with functional changes or abnormal energy metabolism. Left ventricular hypertrophy is a powerful risk factor for sudden cardiac death with different prognostic significance among the various geometric forms. Cyclists may have a combination of mixed eccentric and concentric hypertrophy. Magnetic resonance imaging was used to define left ventricular mass, geometry and function. Thirteen highly trained male cyclis... Abstract

Journal of cardiovascular pharmacology, Volume 28 Suppl 1, 1 1 1996, Pages S37-44 Magnetic resonance techniques for assessment of myocardial viability. van der Wall EE, Vliegen HW, de Roos A, Bruschke AV
In general, the following three standards for myocardial viability can be used: (a) preserved coronary flow (adequate perfusion); (b) preserved wall motion (systolic wall thickening); and (c) preserved metabolism (metabolic integrity). The current magnetic resonance (MR) techniques provide a great potential to measure all three standards of viability. Adequate perfusion can be assessed by spin-echo MR imaging and/or ultrafast MR imaging, systolic wall thickening by cine MR imaging, and the prese... Abstract

To assess the accuracy of quantitative analysis of global and regional wall motion and wall thickening of the left ventricle with cine magnetic resonance (MR), images obtained in eight pigs before and after myocardial infarction were compared with those obtained using gadolinium diethylenetriaminepentaacetic acid (Gd-DTPA)-enhanced multislice spin-echo MR imaging and determination of pathology. The region with abnormal wall motion and wall thickening, as determined with cine MR imaging, identifi... Abstract
