From January 1996 to April 2001, we treated eight patients with subdivided left atrium. Their ages at diagnosis ranged from newborn to 6.4 years. Prominent clinical symptoms were failure to thrive, respiratory symptoms, demand for oxygen, and congestive cardiac failure. Diagnosis was made by transthoracic echocardiography in all cases. Cardiac catheterization was necessary only in those patients who had associated cardiac anomalies, or suspected signs of pulmonary hypertension. In 7 patients, surgery was performed immediately after diagnosis, but one preterm infant died before operation due to neonatal
sepsis
and respiratory distress syndrome. In the postoperative period, one patient developed a severe capillary leak syndrome, and died due to irreversible congestive cardiac failure. The other 6 patients have all been followed up, with good results in the short- and intermediate-term at a mean of 34.3+/-20.2 months. The infants were thriving, had a reduction in the frequency of infections of the respiratory tract, no significant arrhythmias, and showed early recovery from pulmonary hypertension and right ventricular hypertrophy.

The cachexia syndrome is characterised by progressive weight loss and depletion of lean body mass and has long been recognised as a poor prognostic sign. Whilst the clinical features of the wasting process are readily apparent, its pathogenesis is complex and poorly understood. There is increasing evidence that the immune system, in particular inflammatory cytokines, may play an important role in the development of cachexia. The cytokine considered to be the most relevant to this process is tumor necrosis factor alpha (TNF), although other mediators such as interleukin (IL) 1, IL-6 and interferon gamma have also been implicated. Apoptosis represents a potential pathway by which wasting can occur in chronic diseases. Cytokines and their corresponding receptors are known to be important regulators of cell death. Apoptosis has been demonstrated in the skeletal muscle of patients with chronic heart failure (CHF) and is thought to be partly responsible for the significant impairment of functional work capacity associated with this condition. An understanding of the mechanisms that regulate muscle protein breakdown is essential for the development of strategies for treating or even preventing muscle cachexia in patients. It is the aim of this article to review the role of inflammatory cytokines, particularly TNF, in the pathogenesis of wasting and also the potential for anti-cytokine therapy. Although this review will concentrate predominantly on the syndrome of CHF, other chronic illnesses such as liver disease, cancer, and
sepsis
will also be discussed.

A 54-year-old woman with an implantable cardioverter-defibrillator was admitted because of convulsion. Previously, she had suffered methicillin-resistant Staphylococcus aureus (MRSA)
sepsis
induced by a central venous catheter. Despite removal of the central venous catheter and administration of vancomycin, fever and increased C-reactive protein level persisted. MRSA had probably infected the implantable cardioverter-defibrillator system. Gallium scintigraphy showed accumulation at the right subclaviculan area, although local inflammatory signs were absent. Intravascular ultrasonography demonstrated intravenous vegetation at the bifurcation of the right subclavian vein and right internal jugular vein. Antibiotic therapy was not curative, so she underwent extirpation of the intravenous vegetation, which cured the systemic inflammation. Intravascular ultrasonography was useful to differentiate central venous catheter-related infection from implantable cardioverter defibrillator-related infection.

Ten patients were diagnosed with coronary artery fistula (CAF) between 1991 and 1998 in our department. The ages of patients ranged from 3 days to 12 years. Five patients were male and five patients were female. Nine patients had single CAF and 1 patient had dual CAFs. CAFs of 7 patients originated from the left coronary artery, and CAFs of 3 patients originated from the right coronary artery. CAFs of 7 patients terminated at the right ventricle, CAFs of 2 patients terminated at the right atrium, and the CAF of 1 patient terminated at the pulmonary artery. Four patients were diagnosed with CAF in the neonate period. All presented with congestive heart failure. Medical therapy was successful in treating congestive heart failure in 2 of these patients, but the other 2 needed operations. One patient presented with subacute bacterial endocarditis at 12 years of age requiring surgical intervention. One patient had a large left-to-right shunt that was surgically repaired. One patient with dual CAFs underwent coil embolization and the larger CAF achieved complete embolization, but the smaller CAF failed. Follow-up data revealed that 1 patient who received an operation died of
sepsis
due to recurrent bronchiolitis 6 months later. Nine patients were asymptomatic. Because complications including endocarditis may be encountered in later life, we suggest early closure with coil embolization.

The objective of the present study was to identify the nature of a filterable cardiodepressant substance (FCS) that contributes to myocardial dysfunction in a canine model of Escherichia coli septic shock. In a previous study, it was found that FCS increased in plasma after 4 h of bacteremia (Am J Physiol 1993;264:H1402) in which FCS was identified by a bioassay that included a right ventricular trabecular (RVT) preparation. In that study, FCS was only partially identified by pore filtration techniques and was found to be a protein of molecular weight between 10 and 30 K. In the present study, FCS was further purified by size exclusion high-pressure liquid chromatography, until a single band was identified on one-dimensional gel electrophoresis. This band was then subjected to tandem mass spectrometry and protein-sequencing techniques and both techniques identified FCS as lysozyme c (Lzm-S), consistent with that originating from the canine spleen. Confirmatory tests showed that purified Lzm-S produced myocardial depression in the RVT preparation at concentrations achieved during
sepsis
in the in vivo preparation. In addition, Lzm-S inhibited the adrenergic response induced by field stimulation and the beta- agonist isoproterenol in in vitro preparations, these results suggesting that Lzm-S may inhibit the sympathetic response in
sepsis
. The present findings indicate that Lzm-S originating from disintegrating leukocytes from organs such as the spleen contributes to myocardial dysfunction in this model. The mechanism may relate to its binding or hydrolysis of a cardiac membrane glycoprotein thereby interfering with myocardial excitation-contraction coupling in
sepsis
.

A 75-year-old man had a large anterior myocardial infarction complicated by a ventricular septal defect, which was treated in the first 48 h by transcatheter closure using the Amplatzer septal occluder. Treatment was successful (with only mild residual post-procedure shunting) and coronary angioplasty with stent implantation at the point of occlusion of the middle left anterior descending artery was performed in a later intervention. However, the patient died 7 days after the procedure as a result of
sepsis
and ventricular failure.

We report the history of a 60-year-old patient with a multiple myeloma and Staphylococcus aureus associated
sepsis
to whom adenosine in a dose of 6 mg was administered, when a regular, narrow QRS complex tachycardia at a heart rate of 120 beats/minute started. Adenosine led to a complete AV-block and revealed atrial flutter. Atrial flutter waves persisted for about 15 seconds and were followed by atrial and ventricular asystole for about 20 seconds. Repeated nonsustained polymorphic ventricular tachycardias followed and after about 90 seconds sinus rhythm was restored.

The role of preoperative stress single-photon emission computed tomographic (SPECT) imaging in patients with end-stage liver disease who underwent liver transplantation is not well established. We reviewed medical records of patients who had liver transplantation at our institution between January 1998 and November 2001. During this time, 339 patients (213 men, aged 51 +/- 11 years) underwent liver transplantation. Of these, 87 patients had preoperative stress SPECT imaging. Diabetes mellitus (30% vs 11%), hypertension (26% vs 12%), and coronary artery disease (15% vs 7%) were more prevalent in those with than without SPECT (p <0.01 each). The stress SPECT perfusion images were normal in 78 patients (91%) and the left ventricular ejection fraction was 72 +/- 10%. SPECT images revealed ascites in 66% and splenomegaly in 83% of patients. There were 35 total deaths (10%) and 5 nonfatal myocardial infarctions over a mean follow-up of 21 +/- 13 months. Most deaths (32 of 35) were noncardiac and
sepsis
was the most common cause of death. A normal SPECT study had a 99% negative predictive value for perioperative cardiac events. Kaplan-Meier survival curves showed an 87% 2-year cumulative survival rate in the total group. Thus, in patients undergoing liver transplantation, 2-year survival depends on early noncardiac events. A normal stress SPECT study identified patients at a very low risk for early and late cardiac events despite a higher risk profile. SPECT images also revealed unique findings, such as ascites and splenomegaly, which could produce image artifacts and may interfere with accurate image interpretation.

Our previous studies indicate that hearts from septic rats have decreased work with oxygen wasting. The present studies test if there is energy deficit, changes in cardiac mitochondrial content and caspase activation during
sepsis
. Anesthetized, male Sprague-Dawley rats received no surgical treatment (control), laparotomy (sham), or laparotomy with cecal ligation and puncture (CLP) to induce polymicrobial septic shock. Hearts were isolated 12-14 h later. Cardiac work, oxygen consumption, substrate oxidation and energy stores were measured in perfused hearts. Normalized density of mitochondria was determined in ventricles without perfusion by morphometric analysis with electron microscopy. Citrate synthase activity was assessed in homogenates and isolated mitochondria. Cardiac work decreased significantly in CLP (47%), while oxygen consumption and glucose oxidation were unchanged compared with control or sham hearts (oxygen and substrate wasting). Tissue adenosine triphosphate, creatine phosphate and glycogen were lower in CLP hearts (energy deficit). Mitochondrial grid intersects decreased significantly from 151 +/- 8 sham to 130 +/- 4 CLP out of 361 possible intersects and autophagy was observed in CLP hearts. Total activity of citrate synthase decreased in homogenates (99 +/- 8 micromol/min/g wet weight sham vs. 62 +/- 7 CLP, P < 0.05) and in the mitochondrial fraction (27 +/- 1 micromol/min/g wet weight sham to 22 +/- 1 CLP, P < 0.05). Calculated mitochondrial content decreased from 63 +/- 4 mg protein/g wet weight sham to 46 +/- 5 CLP, P < 0.05 (mitochondrial depletion). Caspase-3 activity doubled and tumor necrosis factor alpha content tripled in CLP hearts. CONCLUSIONS. - Oxygen and substrate wasting in CLP occurs with fewer mitochondria and energy deficit, processes that are coincident with caspase-3 activation.
