Kupreishvili K, ter Weeme M, Morré SA, van den Brule AJ, Huybregts MA, Quax PH, ten Velden J, Van Hinsbergh VW, Stooker W, Eijsman L, Niessen HW
Background: Several studies have suggested an association between Chlamydophila pneumoniae (Cp) infection and atherosclerosis. A recent study detected Cp DNA in the saphenous vein of 12% of all patients before bypass grafting and in 38% of failed grafts. We used a system in which human veins were perfused with autologous blood under arterial pressure. Materials and methods: Veins were surplus segments of saphenous veins of coronary artery bypass grafting (CABG) patients. Vein grafts were perfuse...

Torcetrapib does not reduce atherosclerosis beyond atorvastatin and induces more proinflammatory lesions than atorvastatin.
de Haan W, de Vries-van der Weij J, van der Hoorn JW, Gautier T, van der Hoogt CC, Westerterp M, Romijn JA, Jukema JW, Havekes LM, Princen HM, Rensen PC
Background: Although cholesteryl ester transfer protein (CETP) inhibition is regarded as a promising strategy to reduce atherosclerosis by increasing high-density lipoprotein cholesterol, the CETP inhibitor torcetrapib given in addition to atorvastatin had no effect on atherosclerosis and even increased cardiovascular death in the recent Investigation of Lipid Level Management to Understand its Impact in Atherosclerotic Events trial. Therefore, we evaluated the antiatherogenic potential and adve...

Collective experience with hybrid procedures for suprarenal and thoracoabdominal aneurysms.
van de Mortel RH, Vahl AC, Balm R, Buth J, Hamming JF, Schurink GW, de Vries JP
Not every patient is fit for open thoracoabdominal aortic aneurysm (TAAA) repair, nor is every TAAA or juxtarenal abdominal aortic aneurysm suitable for branched or fenestrated endovascular exclusion. The hybrid procedure consists of debranching of the renal and visceral arteries followed by endovascular exclusion of the aneurysm and might be an alternative in these patients. Between May 2004 and March 2006, 16 patients were treated with a hybrid procedure. The indications were recurrent suprare...

Acute effects of alcohol septal ablation on systolic and diastolic left ventricular function in patients with hypertrophic obstructive cardiomyopathy.
Steendijk P, Meliga E, Valgimigli M, Ten Cate FJ, Serruys PW
Objective: Hypertrophic obstructive cardiomyopathy (HOCM) often leads to heart failure, severe symptoms and death. Percutaneous transluminal septal myocardial ablation (PTSMA) by alcohol injection efficiently reduces left ventricular (LV) outflow tract pressure gradient and improves symptoms. We determined acute changes in haemodynamics and systolic and diastolic LV function after PTSMA. Methods: In 17 consecutive patients with symptomatic HOCM referred for PTSMA, the target vessel was determine...

Left cardiac sympathetic denervation for catecholaminergic polymorphic ventricular tachycardia.
Wilde AA, Bhuiyan ZA, Crotti L, Facchini M, De Ferrari GM, Paul T, Ferrandi C, Koolbergen DR, Odero A, Schwartz PJ
Catecholaminergic polymorphic ventricular tachycardia is a potentially lethal disease characterized by adrenergically mediated ventricular arrhythmias manifested especially in children and teenagers. Beta-blockers are the cornerstone of therapy, but some patients do not have a complete response to this therapy and receive an implantable cardioverter-defibrillator (ICD). Given the nature of catecholaminergic polymorphic ventricular tachycardia, ICD shocks may trigger new arrhythmias, leading to t...

Reconstruction of standard 12-lead electrocardiograms from 12-lead electrocardiograms recorded with the Mason-Likar electrode configuration.
Man SC, Maan AC, Kim E, Draisma HH, Schalij MJ, van der Wall EE, Swenne CA
Electrocardiograms (ECGs) made with Mason-Likar electrode configuration (ML-ECGs) show well-known differences from standard 12-lead ECGs (Std-ECGs). We recorded, simultaneously, Std-ECGs and ML-ECGs in 180 subjects. Using these ECGs, 8 x 8 individual and general conversion matrices were created by linear regression, and standard ECGs were reconstructed from ML-ECGs using these matrices. The performance of the matrices was assessed by the root mean square differences between the original Std-ECGs...

[Torcetrapib increases mortality in patients with a high risk of cardiovascular disorders].
Rensen PC, Jukema JW
Inhibition of cholesteryl ester transfer protein (CETP) is generally regarded as a promising strategy to reduce atherosclerosis by increasing HDL cholesterol. Therefore, the potent CETP inhibitor torcetrapib was given in addition to atorvastatin in half of the 15,067 patients with a high cardiovascular risk in the randomized, double-blind 'Investigation of lipid level management to understand its impact in atherosclerotic events' (ILLUMINATE) study. Torcetrapib caused a large increase...

Nonspherical oscillations of ultrasound contrast agent microbubbles.
Dollet B, van der Meer SM, Garbin V, de Jong N, Lohse D, Versluis M
The occurrence of nonspherical oscillations (or surface modes) of coated microbubbles, used as ultrasound contrast agents in medical imaging, is investigated using ultra-high-speed optical imaging. Optical tweezers designed to micromanipulate single bubbles in 3-D are used to trap the bubbles far from any boundary, enabling a controlled study of the nonspherical oscillations of free-floating bubbles. Nonspherical oscillations appear as a parametric instability and display subharmonic behavior: t...
