Aims: Evidence is emerging that, in the setting of isomerism, atrial and bronchial arrangement are not always concordant, nor these patterns harmonious with abdominal organs. We aimed to evaluate concordance between features a cohort patients cardiac malformations known seeking determine whether it was feasible assess complexity on this basis, regard taking note potential value as opposed appen...

BACKGROUND Atrioventricular septal defects (AVSD) are very commonly diagnosed in utero. Heterotaxy/chromosomal abnormalities frequently coexist with AVSD. However, outcomes of fetal AVSD are not precisely known. We attempted to define mortality risk factors in AVSD. METHOD We retrospectively searched our database, electronic records, and echocardiograms with diagnosis of fetal AVSD from 2003 ...

Here we report the syntheses and crystal structures of a series of cobalt(II) and nickel(II) complexes derived from (R)NP2 ligands (where R = OMe(Bz), H(Bz), Br(Bz), Ph) bearing ethylene linkers between a single N and two P donors. The Co(II) complexes generally adopt a tetrahedral configuration of general formula [(NP2)Co(I)(2)], wherein the two phosphorus donors are bound to the metal center ...

OBJECTIVE The purpose of this study was to evaluate the accuracy of the prenatal diagnosis of left isomerism and to assess possible diagnostic and prognostic markers. METHODS We conducted a retrospective review of all previously unpublished cases of left isomerism diagnosed in the prenatal and postnatal periods in 2 tertiary referral centers in Germany over 15 years. RESULTS Among 34 fetuse...

can sense the presence of Brady’s reagent among other nitro compounds! Distortional isomer is also known as bond-stretch isomer differs only in the length of one or more bonds, which has been found to be due to crystallographic disorder in most cases, but shown to exist in Cu(II) due to its plasticity. Here we have used the term distortional isomerism to describe the structures of polyrotaxane ...

OBJECTIVES To clarify the prevalence and mechanism of supraventricular tachycardia in patients with right atrial isomerism. BACKGROUND Paired SA and dual atrioventricular (AV) nodes have been described in patients with right atrial isomerism. However, the clinical significance remains unclear. METHODS From 1987 to 1996, a total of 101 patients (61 male, 40 female) and four fetuses were iden...

BACKGROUND Supraventricular tachycardia (SVT) is common in complex congenital heart disease (CCHD) patients with single-ventricle physiology and may cause hemodynamic deterioration. We reported the outcomes of catheter ablation for such complex SVT in these single-ventricle CCHD patients. METHODS AND RESULTS Patients with single-ventricle physiology (defined as CCHD patients) who received ele...

The reactions of [(thf)2TiCl4] with sodiated 2,2’-bis[2-hydroxy-3,5-di(tert-butyl)benzylideneamino]-1,1’-biphenyl (1 a) and 2,2’-bis[2-hydroxy-3,5-di(tert-butyl)benzylideneamino]-4,4’-dimethyl-1,1’-biphenyl b) yield the corresponding Ti complexes 2 a b. Similarly, 1 reacts [(thf)2ZrCl4] to Zr derivative 3. For a, mixture cis-β trans isomers were observed in solution whereas congener exclusively...
