Relation of epicardial adipose tissue to coronary atherosclerosis.
Djaberi R, Schuijf JD, van Werkhoven JM, Nucifora G, Jukema JW, Bax JJ
Adipose tissue surrounding the coronary arteries has been suggested to induce development of atherosclerosis. We explored the relation between epicardial adipose tissue (EAT) volume and coronary atherosclerosis using multislice computed tomography. The study population consisted of 190 patients who had undergone multislice computed tomographic coronary angiography. Coronary artery calcium score was assessed. In addition, patients were classified as having (1) no atherosclerosis, (2) nonobstructi...

How do you quantify noncalcified plaque?
Schuijf JD, Bax JJ
The ability of multislice computed tomography (MSCT) to visualize not only lumen but also coronary plaques is recognized as an attractive advantage of MSCT over conventional coronary angiography. In particular, the fact that during the administration of contrast not only calcified plaques but also noncalcified plaques can be identified has received enormous interest. Retrospective studies have shown an association between plaques containing noncalcified components and presentation with acute cor...

Surgical training in the Netherlands.
Borel-Rinkes IH, Gouma DJ, Hamming JF
Surgical training in the Netherlands has traditionally been characterized by learning on the job under the classic master-trainee doctrine. Over the past decades, it has become regionally organized with intensive structural training courses, and a peer-based quality control system. Recently, the nationwide programme has been modernized further and now involves a systematic, competency-based education with structural training courses, formalized assessment and room for reflection by residents und...

Imaging in cardiac resynchronisation therapy.
Ypenburg C, van der Wall EE, Schalij MJ, Bax JJ
A substantial number of heart failure (HF) patients do not respond after cardiac resynchronisation therapy (CRT). Recent studies observed that assessment of intraventricular (LV) dyssynchrony may allow identification of potential responders to CRT. In addition, presence of scar tissue and venous anatomy may play a role in the selection of candidates. In this review, an extensive overview of the available LV dyssynchrony measurements is provided using different echocardiographic modalities. In ad...

Establishment of a porcine right ventricular infarction model for cardioprotective actions of xenon and isoflurane.
Hein M, Roehl AB, Baumert JH, Bantes B, Bleilevens C, Bernstein N, Steendijk P, Rossaint R
Background: Right ventricular (RV) function is an important determinant of post-operative outcome. Consequences of RV infarction might be limited by pre-conditioning with volatile anesthetic drugs. Therefore, we used a porcine model of RV ischemia and reperfusion (IR) injury to study the influence of isoflurane and xenon on the extent and degree of myocardial injury. Methods: IR injury was induced by a 90-min ligation of the distal right coronary artery and 120-min reperfusion in thiopental anes...

Normal limits of the spatial QRS-T angle and ventricular gradient in 12-lead electrocardiograms of young adults: dependence on sex and heart rate.
Scherptong RW, Henkens IR, Man SC, Le Cessie S, Vliegen HW, Draisma HH, Maan AC, Schalij MJ, Swenne CA
Background and purpose: Normal limits of the spatial QRS-T angle and spatial ventricular gradient (SVG) are only available from Frank vectorcardiograms (VCGs) of male subjects. We determined normal limits for these variables derived from standard 12-lead electrocardiograms (ECGs) of 660 male and female students aged 18 to 29 years. Methods: A computer algorithm was used that constructed approximated VCG leads by inverse Dower matrix transformation of the 12-lead ECG and subsequently calculated t...

Phenotypic and functional reversal within the early human hematopoietic compartment.
Knaän-Shanzer S, van der Velde-van Dijke I, van de Watering MJ, de Leeuw PJ, Valerio D, van Bekkum DW, de Vries AA
The fate of phenotypically defined human hematopoietic stem cells (hHSCs) in culture and the link between their surface marker expression profile and function are still controversial. We studied these aspects of hHSC biology by relating the expression of the early lineage markers (ELM) CD33, CD38, and CD71 on the surface of human umbilical cord blood (UCB) CD34(+) cells to their long-term nonobese diabetic/severe combined immunodeficient (NOD/SCID) mouse repopulation activity (LT-SRA). In uncult...

Enhanced airway dilation by positive-pressure inflation of the lungs compared with active deep inspiration in patients with asthma.
Slats AM, Janssen K, de Jeu RC, van der Plas DT, Schot R, van den Aardweg JG, Sterk PJ
Deep inspiration temporarily reduces induced airways obstruction in healthy subjects. This bronchodilatory effect of deep inspiration is impaired in asthma. Passive machine-assisted lung inflation may augment bronchodilation compared with an active deep inspiration in patients with asthma by either opening closed airways or by reducing fluid flux across the airway wall during deep inspiration, and thereby increasing the tethering forces on the airway wall. We recruited 24 patients with asthma [1...

Comparison between tissue Doppler imaging and velocity-encoded magnetic resonance imaging for measurement of myocardial velocities, assessment of left ventricular dyssynchrony, and estimation of left ventricular filling pressures in patients with ischemic cardiomyopathy.
Marsan NA, Westenberg JJ, Tops LF, Ypenburg C, Holman ER, Reiber JH, de Roos A, van der Wall EE, Schalij MJ, Roelandt JR, Bax JJ
Velocity-encoded magnetic resonance imaging (VE-MRI), commonly used to perform flow measurements, can be applied for myocardial velocity analysis, similar to tissue Doppler imaging (TDI). In this study, a comparison between VE-MRI and TDI was performed for the assessment of left ventricular dyssynchrony and left ventricular filling pressures. Ten healthy volunteers and 22 patients with heart failure secondary to ischemic cardiomyopathy underwent both VE-MRI and TDI. Longitudinal myocardial peak...

Negative effects of rofecoxib treatment on cardiac function after ischemia-reperfusion injury in APOE3Leiden mice are prevented by combined treatment with thromboxane prostanoid-receptor antagonist S18886 (terutroban).
van der Hoorn JW, Jukema JW, Bekkers ME, Princen HM, Corda S, Emeis JJ, Steendijk P
Objective: Selective cyclooxygenase-2 inhibition by rofecoxib was associated with increased risk of cardiovascular events. We hypothesized that concomitant treatment with thromboxane prostanoid receptor antagonist S18886 might ameliorate possible negative effects. We evaluated the effects of S18886, rofecoxib, and the interaction of both compounds in a combined treatment on myocardial infarct (MI) size and cardiac function after experimental ischemia/reperfusion injury in hyperlipidemic APOE*3Le...
