5.Heterotaxy Syndrome.
Korean Circulation Journal 2011;41(5):227-232
Heterotaxy is defined as an abnormality where the internal thoraco-abdominal organs demonstrate abnormal arrangement across the left-right axis of the body. This broad term includes patients with a wide variety of very complex cardiac lesions. Patients with heterotaxy can be stratified into the subsets of asplenia syndrome and polysplenia syndrome, or the subsets of heterotaxy with isomerism of the right atrial appendages and heterotaxy with isomerism of the left atrial appendages. Treatment of patients with isomerism is determined by the nature and severity of the associated cardiac and extracardiac lesions. Most cardiac operations for patients with isomerism are palliative in nature, since normal anatomy is rarely achieved and mortality rates remain high for patients with heterotaxy syndrome. Patients with left isomerism in general have less severe cardiac malformations than those with right isomerism and, hence, more chance of biventricular repair. For almost all patients with right isomerism, and for many with left isomerism, biventricular repair will not be feasible, and all palliative protocols are then staging procedures prior to a Fontan-type repair. Recent advances in medical management, and improvements in surgical techniques have resulted in improved survival for these patients, and the surgical outcomes are comparable to those with Fontan circulation irrespective of the presence or absence of heterotaxy.

One new neolignan identified as 2, 3-( trans) -dihydro-2-(4-hydroxy-3-methoxyphenyl) -3-[(beta-D-glucopyranosyloxy) methyl]-7-methoxybenzofuran-5-propenoic acid (1) and five known steroidal glycosides namely torvoside A(2), torvoside C(3), torvoside H(4), solanolactoside A (5), (25S)-6alpha-hydroxy-5alpha-spirostan-3-one-6-0-[alpha-L-rhamnopyranosyl-(1-->3-beta3)-beta-D-D-quinovopyr-anoside] (6) were isolated from the fruits of Solanum torvum. Their structures were elucidated on the basis of 1D, 2D NMR and MS spectroscopic analysis.

OBJECTIVETo study the components in aerial part of Siegesbeckia pubescens.
METHODThe compounds were isolated and purified by silica gel, sephadex LH-20 and other column chromatography. Structures were elucidated by spectroscopic methods.
RESULTFour compounds were isolated from S. pubescens and were characterized as dimethyl-21-ethenetylene-darutigenol-3-O-beta-D-glucopyranosid (1), darutigenol (2), darutoside (3), stigmaster-3-O-beta-D-glucopyranosid (4).
CONCLUSIONCompound 1 is a new compound.

The syndromes of left atrial isomerism and right atrial isomerism, called polysplenia and asplenia syndromes, respectively, consist of congenital heart defects with disturbances in normal left right isometry, and the etiology of atrial isomerism remains unclear. Right atrial isomerism is traditionally associated with severe cardiac defects, especially complete atrioventricular septal defect, transposition of great arteries, pulmonary atresia, and total anomalous pulmonary venous return. Recently, we encountered one case of asplenia diagnosed by prenatal ultrasonography. We report a case with brief review of the literatures.

Surface ECG findings in 29 patients with left isomerism were reviewed. Among the total 46 wave axis distributions, 25(54%) were abnormal axis, not originated from sinus node. Congenital atrioventricular block was found in 2 children. 6 patients showed the bradycardia and junctional escape rhythm intermittently or persistently. 4 of them, not related with heart surgery, were much older than 2 patients who showed these ECG findings after heart surgery. These ECG findings suggested the possibility of occurrence of sinus node or subsidiary pacemaker dysfunction in the patients with left isomerism, especially in the older patients. So we thought that electrophysiologic evaluation is necessary in some patients with left isomerism.
