Dirksen MS, Lamb HJ, Doornbos J, Bax JJ, Jukema JW, de Roos A
Magnetic resonance angiography (MRA) is a promising method for noninvasive coronary artery imaging. The interesting features of coronary MRA are its non-invasive nature, the absence of ionizing radiation, and the possibility of imaging the coronary arteries without exogenous contrast. Moreover, three-dimensional volume information and tomographic image planes in any direction can be obtained. The current review presents an overview of the recent technical developments of coronary MRA and the pot... Abstract

European journal of echocardiography : the journal of the Working Group on Echocardiography of the European Society of Cardiology, Volume 3, Issue 4, 1 1 2002, Pages 301-302 Non-compaction cardiomyopathy-echocardiographic diagnosis. Bax JJ, Lamb HJ, Poldermans D, Schalij MJ, de Roos A, van der Wall EE
Non-compaction cardiomyopathy is a recently recognized disorder caused by a defect in endomyocardial morphogenesis. The disease can present with heart failure, systemic embolic events, and ventricular arrhythmias. Long-term prognosis is poor. Echocardiography is used to confirm the diagnosis; in the current case-report, we describe the typical abnormalities observed on echocardiography in a patient with non-compaction cardiomyopathy.

The accurate noninvasive diagnosis and functional evaluation of coronary artery disease is an important step in selecting the appropriate management strategy. Dobutamine stress myocardial perfusion imaging is an alternative to exercise in patients with limited exercise capacity. In many centers, the test is performed on patients who have a contraindication for vasodilator stress testing. Recent studies have shown hyperemia induced by the standard dobutamine-atropine stress test is not less than... Abstract

American heart journal, Volume 144, Issue 5, 1 1 2002, Pages 865-869 Assessment of residual myocardial viability in regions with chronic electrocardiographic Q-wave infarction. Schinkel AF, Bax JJ, Boersma E, Elhendy A, Vourvouri EC, Roelandt JR, Poldermans D
Background: Q waves on the electrocardiogram are often considered to be reflective of irreversibly scarred myocardium due to antecedent transmural myocardial infarction. However, there are some indications that residual viable tissue may be present in Q-wave-infarcted regions. It is clinically relevant to know how many Q-wave regions contain viable tissue because these patients may benefit from revascularization in terms of improvement of function and long-term survival. Methods: Patients (n = 1... Abstract
