The American journal of cardiology, Volume 93, Issue 7, 1 1 2004, Pages 860-863 Comparison of benefits from cardiac resynchronization therapy in patients with ischemic cardiomyopathy versus idiopathic dilated cardiomyopathy. Molhoek SG, Bax JJ, van Erven L, Bootsma M, Boersma E, Steendijk P, van der Wall EE, Schalij MJ
Cardiac resynchronization therapy (CRT) is a recently introduced therapeutic option for patients with severe heart failure and intraventricular conduction disturbances. However, it is estimated that 20% to 30% of patients may not respond to CRT. Patients with ischemic cardiomyopathy (IC) may respond less favorably to CRT compared with patients with idiopathic dilated cardiomyopathy (IDC). Accordingly, the beneficial effects of CRT were evaluated in 2 subsets of patients (IC and IDC). Seventy-fou... Abstract

The international journal of cardiovascular imaging, Volume 20, Issue 2, 1 1 2004, Pages 113-116 Thrombus in the left atrial appendage detected by intracardiac echocardiography. Jongbloed MR, Bax JJ, van der Wall EE, Schalij MJ
Radiofrequency catheter ablation (RFCA) at the ostium of the pulmonary veins can potentially cure atrial fibrillation. Left-sided ablation procedures may carry a risk of thrombo-embolic events. Emboli from intracardiac thrombus originate from the left atrial appendage (LAA) in a substantial number of patients. The presence of spontaneous echo contrast in the left atrium (LA) and LAA peak emptying flow < or = 20 cm/s are also significantly related to thrombo-embolic events. Evaluation of the a... Abstract

Growth hormone therapy in patients with idiopathic dilated cardiomyopathy and ischemic cardiac failure has revealed varying effects on systolic function, probably related to the response in serum insulin-like growth factor I (IGF-I) levels. As diastolic function has not been studied thoroughly, we studied the effects of 6 months of recombinant human growth hormone (rh GH) treatment on systolic and diastolic function in patients with ischemic cardiac failure, using cardiovascular magnetic resonan...

Slart RH, Bax JJ, de Jong RM, de Boer J, Lamb HJ, Mook PH, Willemsen AT, Vaalburg W, van Veldhuisen DJ, Jager PL
Unlabelled: The aim of this study was to compare left ventricular (LV) volumes and regional wall motion determined by PET with those determined by the reference technique, cardiovascular MRI. Methods: LV end-diastolic volume (LVEDV), LV end-systolic volume (LVESV), and LV ejection fraction (LVEF) were measured and regional wall motion was scored in 38 patients with chronic coronary artery disease by both gated (18)F-FDG PET and MRI. A 9-segment model was used for PET and MRI to assess regional w... Abstract

The American journal of cardiology, Volume 93, Issue 4, 1 1 2004, Pages 394-398 Comparison of functional recovery of mildly hypokinetic versus severely dysfunctional left ventricular segments after revascularization in patients with ischemic cardiomyopathy. Rizzello V, Biagini E, Schinkel AF, Bountioukos M, Boersma E, Vourvouri EC, Sozzi FB, Elhendy A, Roelandt JR, Poldermans D, Bax JJ
Dysfunctional left ventricular (LV) segments showing contractile reserve during dobutamine stress echocardiography (DSE) are considered viable myocardium; functional recovery is expected after revascularization. Many segments, however, particularly mildly hypokinetic segments, do not recover. The reason for this failure is unknown. Two-dimensional echocardiography at rest and low-high-dose DSE were performed before revascularization in 114 consecutive patients with ischemic cardiomyopathy. Two-d... Abstract

Jongbloed MR, Bax JJ, van der Burg AE, Van der Wall EE, Schalij MJ
Aims: Ventricular tachycardia (VT) frequently has an anatomical substrate. Identification of areas prone to arrhythmogenicity facilitates radiofrequency catheter ablation (RFCA). Furthermore, direct monitoring of complications potentially increases safety of RFCA. The aim of this study was to evaluate the feasibility of guiding RFCA of VT with intracardiac echocardiography (ICE), in order to improve outcome and procedural safety. Methods and results: Eleven patients (age 59 +/- 15 years) with dr... Abstract

Purpose: To assess the potential long-term beneficial effects of statin use after successful abdominal aortic surgery. Methods: Between 1991 and 2001, 570 patients underwent abdominal aortic aneurysm repair at the Erasmus Medical Center. Of the 519 patients (91%) who survived surgery beyond 30 days, 510 (98%) were followed for a median of 4.7 years (interquartile range, 2.7 to 7.3 years). These patients were evaluated for use of statins and beta-blockers, and for clinical risk factors (e.g., adv... Abstract

Journal of cardiovascular magnetic resonance : official journal of the Society for Cardiovascular Magnetic Resonance, Volume 6, Issue 4, 1 1 2004, Pages 767-776 Accurate and reproducible mitral valvular blood flow measurement with three-directional velocity-encoded magnetic resonance imaging. Westenberg JJ, Danilouchkine MG, Doornbos J, Bax JJ, van der Geest RJ, Labadie G, Lamb HJ, Versteegh MI, de Roos A, Reiber JH
A new method for quantifying the transvalvular flow through the mitral valve (MV) based on three-directional velocity-encoded magnetic resonance imaging (MRI) is presented. For thirty time phases during one cardiac cycle, the three-dimensional (3D) velocity vector field of the blood flow is reconstructed from the MRI measurement. Retrospectively, for each time phase, the MV-plane is indicated manually in the velocity data and the flow through this plane is determined, representing the MV flow. M... Abstract

Contractile function in patients with ischemic left ventricular (LV) dysfunction may improve after myocardial revascularization. Currently, the incidence of contractile function recovery after revascularization in these patients is unclear. The aim of this study was to assess the incidence of function improvement after myocardial revascularization in patients with ischemic LV dysfunction. A total of 258 consecutive patients (aged 59 +/- 12 years) with severely depressed LV ejection fractions (EF... Abstract
