Why, how and when do we need to optimize the setting of cardiac resynchronization therapy?
Bertini M, Delgado V, Bax JJ, Van de Veire NR
Current cardiac resynchronization therapy (CRT) devices allow manipulation of the atrioventricular (AV) and interventricular (VV) timings in order to maximize the left ventricular (LV) performance. Multiple echocardiographic and non-echocardiographic methods have been proposed to optimize AV and VV intervals but no consensus has been reached on which methodology should preferably be used. Furthermore, different physiologic conditions, such as rest and exercise, may markedly change LV loading con...

Preliminary insight into the age and origin of the Labeobarbus fish species flock from Lake Tana (Ethiopia) using the mtDNA cytochrome b gene.
de Graaf M, Megens HJ, Samallo J, Sibbing F
The high diversity of Cyprinid fish in Ethiopia's Lake Tana appears to be an example of ecological differentiation and assortative mating leading to rapid sympatric speciation. Lake Tana's Labeobarbus species flock consists of 15 morphological and ecological distinct species. This is the first attempt to determine the age and origin and inter-species relationships of Lake Tana's Labeobarbus species using the mtDNA cytochrome b gene. Analysis of cytchrome b sequences shows that Lak...

Xenon and isoflurane improved biventricular function during right ventricular ischemia and reperfusion.
Hein M, Roehl AB, Baumert JH, Bleilevens C, Fischer S, Steendijk P, Rossaint R
Background: Although anesthetics have some cardioprotective properties, these benefits are often counterbalanced by their negative inotropic effects. Xenon, on the other hand, does not influence myocardial contractility. Thus, xenon may be a superior treatment for the maintenance of global hemodynamics, especially during right ventricular ischemia, which is generally characterized by a high acute complication rate. Methods: The effects of 70 vol% xenon and 0.9 vol% isoflurane on biventricular fu...

Short-term hemodynamic effects of cardiac resynchronization therapy in patients with heart failure, a narrow QRS duration, and no dyssynchrony.
Williams LK, Ellery S, Patel K, Leyva F, Bleasdale RA, Phan TT, Stegemann B, Paul V, Steendijk P, Frenneaux M
Background: Cardiac resynchronization therapy produces both short-term hemodynamic and long-term symptomatic/mortality benefits in symptomatic heart failure patients with a QRS duration >120 ms. This is conventionally believed to be due principally to relief of dyssynchrony, although we recently showed that relief of external constraint to left ventricular filling may also play a role. In this study, we evaluated the short-term hemodynamic effects in symptomatic patients with a QRS duration

Usefulness of carotid intima-media thickness in patients with diabetes mellitus as a predictor of coronary artery disease.
Djaberi R, Schuijf JD, de Koning EJ, Rabelink TJ, Smit JW, Kroft LJ, Pereira AM, Scholte AJ, Spaans M, Romijn JA, de Roos A, van der Wall EE, Jukema JW, Bax JJ
Identification of asymptomatic patients with diabetes mellitus (DM) at increased risk for coronary artery disease (CAD) remains a challenge. Carotid intima-media thickness (CIMT) has been proposed as a surrogate marker for CAD but only limited data are available. The purpose of the study was to evaluate the potential of CIMT for prediction of CAD in asymptomatic patients with DM. Prospectively, CIMT of the left and right common carotid arteries was assessed by B-mode ultrasound in 150 asymptomat...

The outflow tract in transposition of the great arteries: an anatomic and morphologic study.
Lalezari S, Mahtab EA, Bartelings MM, Wisse LJ, Hazekamp MG, Gittenberger-de Groot AC
Background: Neoaortic root dilatation is observed after the arterial switch operation for transposition of the great arteries. Although structural differences in the vessel wall of these patients may be of influence, we hypothesize that a histomorphologic difference in composition and embedding of the fibrous annulus in transposition of the great arteries may play a role in neoaortic root dilatation. Methods: Two normal human hearts and two unoperated human hearts with transposition of the great...

Post-intervention IVUS is not predictive for very late in-stent thrombosis in drug-eluting stents.
Bergheanu SC, Van der Hoeven BL, Hassan AK, Dijkstra J, Rosendaal FR, Liem SS, Schalij MJ, Van der Bom JG, Jukema JW
Objectives: Stent thrombosis is a life-threatening complication associated with sudden death and acute myocardial infarction. Histopathologic studies have linked the occurrence of very late stent thrombosis in drug-eluting stents (DES) with delayed endothealisation and stent malapposition. Our aim was to investigate if late stent malapposition in DES could be predicted by immediate postintervention intra-vascular ultrasonography (IVUS). Methods and results: From our MISSION! database of 184 cons...
