A comparative regional analysis of coronary atherosclerosis and calcium score on multislice CT versus myocardial perfusion on SPECT.
Schuijf JD, Wijns W, Jukema JW, Decramer I, Atsma DE, de Roos A, Stokkel MP, Dibbets-Schneider P, van der Wall EE, Bax JJ
Unlabelled: For the noninvasive evaluation of coronary artery disease (CAD), both multislice CT and gated SPECT are available. How these 2 modalities relate, however, is yet unclear. The purpose of this study was to perform a head-to-head comparison of the results of multislice CT and gated SPECT on a regional basis (per vessel distribution territory) in patients with known or suspected CAD. Methods: One hundred forty patients underwent both multislice CT for coronary calcium scoring and coronar...

Beneficial hemodynamic and clinical effects of surgical ventricular restoration in patients with ischemic dilated cardiomyopathy.
Tulner SA, Bax JJ, Bleeker GB, Steendijk P, Klautz RJ, Holman ER, Schalij MJ, Dion RA, van der Wall EE
Background: Surgical ventricular restoration is increasingly applied in patients with ischemic dilated cardiomyopathy. Previous studies show promising results with regard to survival and clinical outcome. However, a comprehensive midterm analysis of this approach on left ventricular (LV) and right ventricular function is not yet available. We investigated biventricular function and clinical status at 6-month follow-up. Methods: We investigated the effects of surgical ventricular restoration on c...

Non-invasive visualization of the cardiac venous system in coronary artery disease patients using 64-slice computed tomography.
Van de Veire NR, Schuijf JD, De Sutter J, Devos D, Bleeker GB, de Roos A, van der Wall EE, Schalij MJ, Bax JJ
Objectives: This study was designed to evaluate the value of 64-slice computed tomography (CT) to visualize the cardiac veins and evaluate the relation between variations in venous anatomy and history of infarction. Background: Cardiac resynchronization therapy (CRT) is an attractive treatment for selected heart failure patients. Knowledge of venous anatomy may help in identifying candidates for successful left ventricular lead implantation. Methods: The 64-slice CT of 100 individuals (age 61 +/...

Impact of glomerular filtration rate on minor troponin T elevations for risk assessment in patients undergoing operation for abdominal aortic aneurysm or lower extremity arterial obstruction.
Feringa HH, Bax JJ, de Jonge R, Elhendy A, van Domburg RT, Dunkelgrun M, Schouten O, Karagiannis SE, Vidakovic R, Poldermans D
Debate surrounds the impact of renal function on the prognostic value of minor troponin T release in vascular surgery patients. The objective of this study was to assess the long-term prognostic value of minor degrees of troponin T release in patients who undergo major vascular surgery, especially those with concomitant renal dysfunction. Survivors of major noncardiac vascular surgery (n = 558) were preoperatively screened for cardiac risk factors and renal function. Serial troponin T was measur...

Extent of viability to predict response to cardiac resynchronization therapy in ischemic heart failure patients.
Ypenburg C, Schalij MJ, Bleeker GB, Steendijk P, Boersma E, Dibbets-Schneider P, Stokkel MP, van der Wall EE, Bax JJ
Unlabelled: The response to cardiac resynchronization therapy (CRT) varies significantly among individuals. Preliminary data suggest that the presence of myocardial viability may be important for response to CRT. The aim of this study was to evaluate whether the extent of viability could predict response to CRT after 6 mo. Methods: Sixty-one consecutive patients with advanced heart failure, left ventricular ejection fraction < 35%, QRS duration > 120 ms, and chronic coronary artery disease...

Sustained effect of autologous bone marrow mononuclear cell injection in patients with refractory angina pectoris and chronic myocardial ischemia: twelve-month follow-up results.
Beeres SL, Bax JJ, Dibbets-Schneider P, Stokkel MP, Fibbe WE, van der Wall EE, Schalij MJ, Atsma DE
Background: Cell therapy has recently been introduced to treat patients with refractory angina. Because most studies have only included short-term follow-up, the effects of cell therapy over a longer period are unknown. Methods: In 25 patients (mean age 64 +/- 10 years, 21 men) with refractory angina, a total of 84 +/- 29 x 10(6) bone marrow-derived mononuclear cells was injected intramyocardially in regions with ischemia on technetium-99m tetrofosmin single-photon emission computed tomography....

Implantable defibrillator early after primary percutaneous intervention for ST-elevation myocardial infarction: rationale and design of the Defibrillator After Primary Angioplasty (DAPA) trial.
Ottervanger JP, Ramdat Misier AR, Zijlstra F, Schalij MJ, Wever E, Jordaens LJ, Henriques JP, de Boer MJ, Robbe HW, Wellens HJ, DAPA Investigators
Background: It has been shown that an implantable cardioverter defibrillator (ICD) may be beneficial when added to optimal drug treatment in patients with reduced left ventricular function who survive a myocardial infarction (MI). However, it is not known whether patients with increased risk of death after primary percutaneous coronary intervention (PCI) for ST-elevation MI also have benefit of prophylactic ICD therapy to reduce sudden cardiac death. Methods and study design: The DAPA trial is d...

Fragmented, long-duration, low-amplitude electrograms characterize the origin of focal atrial tachycardia.
De Groot NM, Schalij MJ
Background: Focal atrial tachycardias (FAT) originate from areas with poor cell-to-cell coupling. Due to cellular uncoupling extracellular potentials become fractionated. The degree of fragmentation may be used to identify the site of origin of FAT prior to catheter ablation. We studied electrical fragmentation in relation to the distance to the site of earliest activity during FAT. Methods: Three-dimensional (3-D) electroanatomical activation/voltage maps obtained from patients (n = 15: 6 male,...

Right ventricular pacing can induce ventricular dyssynchrony in patients with atrial fibrillation after atrioventricular node ablation.
Tops LF, Schalij MJ, Holman ER, van Erven L, van der Wall EE, Bax JJ
Objectives: This study was designed to assess the effects of long-term right ventricular (RV) pacing on left ventricular (LV) dyssynchrony, LV function, and heart failure symptoms. Background: Atrioventricular (AV) node ablation and subsequent long-term RV pacing is a well-established treatment option in patients with atrial fibrillation (AF). Methods: In 55 patients with drug-refractory AF, AV node ablation and implantation of a pacemaker was performed. At baseline and after a mean of 3.8 +/- 1...

Changes in lamina structure are followed by spatial reorganization of heterochromatic regions in caspase-8-activated human mesenchymal stem cells.
Raz V, Carlotti F, Vermolen BJ, van der Poel E, Sloos WC, Knaän-Shanzer S, de Vries AA, Hoeben RC, Young IT, Tanke HJ, Garini Y, Dirks RW
Apoptosis is fundamental to the regulation of homeostasis of stem cells in vivo. Whereas the pathways underlying the molecular and biochemical details of nuclear breakdown that accompanies apoptosis have been elucidated, the precise nature of nuclear reorganization that precedes the demolition phase is not fully understood. Here, we expressed an inducible caspase-8 in human mesenchymal stem cells, and quantitatively followed the early changes in nuclear organization during apoptosis. We found th...

Epicardial cells of human adults can undergo an epithelial-to-mesenchymal transition and obtain characteristics of smooth muscle cells in vitro.
van Tuyn J, Atsma DE, Winter EM, van der Velde-van Dijke I, Pijnappels DA, Bax NA, Knaän-Shanzer S, Gittenberger-de Groot AC, Poelmann RE, van der Laarse A, van der Wall EE, Schalij MJ, de Vries AA
Myocardial and coronary development are both critically dependent on epicardial cells. During cardiomorphogenesis, a subset of epicardial cells undergoes an epithelial-to-mesenchymal transition (EMT) and invades the myocardium to differentiate into various cell types, including coronary smooth muscle cells and perivascular and cardiac interstitial fibroblasts. Our current knowledge of epicardial EMT and the ensuing epicardium-derived cells (EPDCs) comes primarily from studies of chick and mouse...
