Real-time 3-dimensional echocardiography early after acute myocardial infarction: incremental value of echo-contrast for assessment of left ventricular function.
Nucifora G, Marsan NA, Holman ER, Siebelink HM, van Werkhoven JM, Scholte AJ, van der Wall EE, Schalij MJ, Bax JJ
Background: Accurate and reproducible assessment of left ventricular (LV) systolic function is important in patients with acute myocardial infarction (AMI). Real-time 3-dimensional echocardiography (RT3DE) is an accurate technique, but it relies heavily on good image quality. The aim of the present study was to evaluate the incremental value of contrast-enhanced RT3DE. Methods: A total of 140 consecutive patients (58 +/- 11 years, 78% men) with ST-elevation AMI clinically underwent nonenhanced a...

Therapeutic decisions for patients with symptomatic severe aortic stenosis: room for improvement?
van Geldorp MW, van Gameren M, Kappetein AP, Arabkhani B, de Groot-de Laat LE, Takkenberg JJ, Bogers AJ
Objective: Symptomatic severe aortic stenosis is an indication for aortic valve replacement. Some patients are denied intervention. This study provides insight into the proportion of conservatively treated patients and into the reasons why conservative treatment is chosen. Methods: Of a patient cohort presenting with severe aortic stenosis between 2004 and 2007, medical records were retrospectively analyzed. Only symptomatic patients (n=179) were included. We studied their characteristics, treat...

Left ventricular mechanical dyssynchrony is load independent at rest and during endotoxaemia in a porcine model.
A'roch R, Steendijk P, Oldner A, Weitzberg E, Konrad D, Johansson G, Haney M
Aim: In diseased or injured states, the left ventricle displays higher degrees of mechanical dyssynchrony. We aimed at assessing mechanical dyssynchrony ranges in health related to variation in load as well as during acute endotoxin-induced ventricular injury. Methods: In 16 juvenile anaesthetized pigs, a five-segment conductance catheter was placed in the left ventricle as well as a balloon-tipped catheter in the inferior vena cava. Mechanical dyssynchrony during systole, including dyssynchrony...

Mannose binding lectin deficiency and triglyceride-rich lipoprotein metabolism in normolipidemic subjects.
Alipour A, van Oostrom AJ, Van Wijk JP, Verseyden C, Plokker HW, Jukema JW, Rabelink AJ, Castro Cabezas M
Mannose binding lectin (MBL) is one of the three initiators of complement activation and is therefore closely linked to inflammation. MBL deficiency has been associated with the generation of atherosclerosis. Since atherosclerosis, the complement system and postprandial lipemia are linked to inflammation, we studied postprandial lipoprotein metabolism in MBL deficiency. An observational study was carried out in 107 volunteers (21% MBL deficient). Classical cardiovascular risk factors were not di...

Haplotype-sharing analysis implicates chromosome 7q36 harboring DPP6 in familial idiopathic ventricular fibrillation.
Alders M, Koopmann TT, Christiaans I, Postema PG, Beekman L, Tanck MW, Zeppenfeld K, Loh P, Koch KT, Demolombe S, Mannens MM, Bezzina CR, Wilde AA
Idiopathic Ventricular Fibrillation (IVF) is defined as spontaneous VF without any known structural or electrical heart disease. A family history is present in up to 20% of probands with the disorder, suggesting that at least a subset of IVF is hereditary. A genome-wide haplotype-sharing analysis was performed for identification of the responsible gene in three distantly related families in which multiple individuals died suddenly or were successfully resuscitated at young age. We identified a h...

Wall motion score index predicts mortality and functional result after surgical ventricular restoration for advanced ischemic heart failure.
Klein P, Holman ER, Versteegh MI, Boersma E, Verwey HF, Bax JJ, Dion RA, Klautz RJ
Objective: Advanced ischemic heart failure can be treated with surgical ventricular restoration (SVR). While numerous risk factors for mortality and recurrent heart failure have been identified, no plain predictor for identifying SVR patients with left ventricular damage beyond recovery is yet available. We tested echocardiographic wall motion score index (WMSI) as a predictor for mortality or poor functional result. Methods: One hundred and one patients electively operated between April 2002 an...

Double aortic arch with double aneuploidy--rare anomaly in combined Down and Klinefelter syndrome.
Gerretsen MF, Peelen W, Rammeloo LA, Koolbergen DR, Hruda J
A 14-month-old boy with double aneuploidy and a double aortic arch suffered from frequently recurrent severe feeding and respiratory problems. Chromosomal analysis showed a 48,XXY + 21 karyotype: a double aneuploidy of Down syndrome (DS) and Klinefelter syndrome (KS). Only four cases of double aneuploidy (DS + KS) associated with congenital heart defects have been published of which none had a double aortic arch. Our case report should draw attention to the possibility of a double aortic arch in...

Fusion protein is the main determinant of metapneumovirus host tropism.
de Graaf M, Schrauwen EJA, Herfst S, van Amerongen G, Osterhaus ADME, Fouchier RAM
Human metapneumovirus (HMPV) and avian metapneumovirus subgroup C (AMPV-C) infect humans and birds, respectively. This study confirmed the difference in host range in turkey poults, and analysed the contribution of the individual metapneumovirus genes to host range in an in vitro cell-culture model. Mammalian Vero-118 cells supported replication of both HMPV and AMPV-C in contrast to avian quail fibroblast (QT6) cells in which only AMPV-C replicated to high titres. Inoculation of Vero-118 and QT...

The role of speckle tracking strain imaging in cardiac pacing.
Tops LF, Delgado V, Bax JJ
In recent years, concerns have been raised about possible harmful effects of long-term right ventricular (RV) apical pacing. These detrimental effects may be related to changes in left ventricular (LV) mechanics during RV apical pacing. As a consequence, alternative RV pacing sites have been proposed, and in selected patients an upgrade from RV to biventricular pacing may be considered. Novel two-dimensional (2D) speckle tracking strain imaging allows detailed evaluation of LV mechanics, includi...

A rare cause of mental motor retardation: recessive congenital methemoglobinemia type II.
Yüksel D, Senbil N, Yilmaz D, Yarali N, Gürer YK
Recessive congenital methemoglobinemia (RCM) is a very rare disorder caused by NADH- cytochrome b5 reductase (cytb5r) deficiency. It has been classified into four types. Type I presents with mild cyanosis due to a significant deficiency of cytb5r in erythrocytes only. In type II, the deficiency occurs in all tissues and causes growth and mental retardation and other neurological impairments. RCM types I and II are caused by a defect in a single gene, which is located on chromosome 22 (locus DIA...

Tranexamic acid and aprotinin in low- and intermediate-risk cardiac surgery: a non-sponsored, double-blind, randomised, placebo-controlled trial.
Later AF, Maas JJ, Engbers FH, Versteegh MI, Bruggemans EF, Dion RA, Klautz RJ
Objective: Tranexamic acid has been suggested to be as effective as aprotinin in reducing blood loss and transfusion requirements after cardiac surgery. Previous studies directly comparing both antifibrinolytics focus on high-risk cardiac surgery patients only or suffer from methodological problems. We wanted to compare the effectiveness of tranexamic acid versus aprotinin in reducing postoperative blood loss and transfusion requirements in the patient group representing the majority of cardiac...
