Pregnancy in women with pulmonary arterial hypertension (PAH) is considered to be associated with prohibitive maternal mortality. During the past decade, new advanced therapies for PAH have emerged and progress in high-risk pregnancy management has been made. We examined whether these changes have improved outcomes in parturients with PAH. A systematic review of all cases of parturients with idiopathic pulmonary hypertension (iPAH), congenital heart disease associated with PAH (CHD-PAH), or PAH of other aetiology (oPH) published in the past decade (1997-2007) was performed. Outcome data from this study were then compared with relevant data published between 1978 and 1996. Forty-eight case reports or case series met the inclusion criteria, totalling 73 parturients with PAH. Seventy-two per cent of patients with iPAH were receiving advanced therapies, compared with 52% of CHD-PAH and 47% of oPH. Although a publication bias cannot be excluded, overall maternal mortality was significantly lower compared with previous era (25 vs. 38%, P = 0.047) and was 17% in iPAH, 28% in CHD-PAH, and 33% in oPH. Seventy-eight per cent of deaths occurred within the first month after delivery. Primigravidae and parturients who received general anaesthesia were at higher risk of death (OR 3.70, 95% CI 1.15-12.5, P = 0.03 and OR 4.37, 95% CI 1.28-16.50, P = 0.02, respectively). Maternal mortality in parturients with PAH remains prohibitively high, despite lower death rates than previous decades. Early advice on pregnancy risks, including contraception, remains paramount. Women with PAH who become pregnant warrant a multidisciplinary approach with consideration of advanced therapies.

Chronic kidney disease and elevated serum C-reactive protein (CRP) have been suggested as clinical risk factors for cardiac attacks. The present study investigated postmortem blood urea nitrogen (BUN), creatinine (Cr) and CRP levels in the peripheral blood of sudden cardiac death cases. Adult autopsy cases of ischemic heart diseases (n=153, >20 years of age), including acute myocardial infarction (AMI, n=71), recurrent myocardial infarction (RMI, n=47), acute ischemic heart disease without infarction (AIHD, n=27) and chronic ischemic heart disease (CIHD, n=8), were examined and compared with chronic congestive heart disease (CHD, n=24), spontaneous cerebral hemorrhage (SCH, n=17) and mechanical asphyxiation (n=32). BUN was slightly higher for RMI and CHD, although Cr was slightly higher for SCH. CRP was higher for AMI than for AIHD. The correlation between BUN and Cr levels was significant for AMI, AIHD and CHD, but insignificant for RMI and CIHD. Heart weight was larger for all heart diseases and SCH than for asphyxiation, and was larger for RMI and CHD but lower for AIHD and CIHD among them. Body mass index (BMI) was slightly higher for AMI, RMI, AIHD and CHD, remaining within the reference interval in most cases, but was lower for CIHD. These findings suggest different risk factors or etiologies, including active atherosclerosis, latent renal failure, dehydration and cardiac hypertrophy, for sudden deaths due to these heart diseases.

CHD is the leading cause of worldwide mortality. The prevalence of heart disease has been linked to the adoption of a sedentary lifestyle and the increased dietary dependence on saturated fats from animal sources and the intake of refined foods. Elevated blood cholesterol level is one of the major risk factors for CHD. While cholesterol-lowering drug therapy (statins) has been effective in reducing the risk of heart disease, there are those individuals who are unwilling or because of muscle pains or raised levels of liver or muscle enzymes are unable to take cholesterol-lowering medication. Fortunately, there is evidence linking a number of dietary components to CHD risk reduction. The strength of this evidence has prompted various regulatory bodies to advocate diet as the first line of defence for primary prevention of heart disease. It was therefore decided to combine four dietary components that have been shown to lower blood cholesterol concentrations (nuts, plant sterols, viscous fibre and vegetable protein) in a dietary portfolio in order to determine whether the combined effect is additive. In a metabolically-controlled setting this dietary portfolio has proved to be as effective as a starting dose of a first-generation statin cholesterol-lowering medication in reducing the risk of CHD. The dietary portfolio has also been shown to be effective in sustaining a clinically-significant effect in the long term under a 'real-world' scenario. However, success of the diet depends on compliance and despite the accessibility of the foods adherence has been found to vary greatly. Overall, the evidence supports the beneficial role of the dietary portfolio in reducing blood cholesterol levels and CHD risk.

MRI and CT perform an important complementary role to echocardiography in the initial evaluation of the neonate with congenital heart disease. This review will focus on the indications and technique of neonatal cardiac imaging with MRI and CT. It also includes a brief discussion of the role of conventional radiography in neonatal CHD and the safety of iodinated and gadolinium-based contrast agents in this age group.

A new population of patients in cardiology has been growing steadily so that the number of grown-ups with congenital heart disease (GUCH) is almost equal to those under paediatric care. The dramatic improvement in survival should lead to a larger number of GUCH patients than children with CHD in the new millennium. Although echocardiography remains the imaging modality of choice, cross-sectional imaging techniques have a decision-aiding function for the postoperative evaluation of surgical reconstructions as well as in the preparation of complex interventional procedures. Cardiovascular CT and MRI are often complementary in providing comprehensive complex anatomical evaluation, haemodynamic assessment of residual postoperative lesions and complications of surgery. A thorough understanding of postsurgical corrections is a prerequisite for choosing the optimal imaging techniques and achieving an accurate evaluation.

The aim of this prospective, multicenter study was to define the etiology and clinical features of acute kidney injury (AKI) in a pediatric patient cohort and to determine prognostic factors. Pediatric-modified RIFLE (pRIFLE) criteria were used to classify AKI. The patient cohort comprised 472 pediatric patients (264 males, 208 females), of whom 32.6% were newborns (median age 3 days, range 1-24 days), and 67.4% were children aged >1 month (median 2.99 years, range 1 month-18 years). The most common medical conditions were prematurity (42.2%) and congenital heart disease (CHD, 11.7%) in newborns, and malignancy (12.9%) and CHD (12.3%) in children aged >1 month. Hypoxic/ischemic injury and sepsis were the leading causes of AKI in both age groups. Dialysis was performed in 30.3% of newborns and 33.6% of children aged >1 month. Mortality was higher in the newborns (42.6 vs. 27.9%; p < 0.005). Stepwise multiple regression analysis revealed the major independent risk factors to be mechanical ventilation [relative risk (RR) 17.31, 95% confidence interval (95% CI) 4.88-61.42], hypervolemia (RR 12.90, 95% CI 1.97-84.37), CHD (RR 9.85, 95% CI 2.08-46.60), and metabolic acidosis (RR 7.64, 95% CI 2.90-20.15) in newborns and mechanical ventilation (RR 8.73, 95% CI 3.95-19.29), hypoxia (RR 5.35, 95% CI 2.26-12.67), and intrinsic AKI (RR 4.91, 95% CI 2.04-11.78) in children aged >1 month.

Congenital heart disease represent a large proportion of heart disease in pregnancy. With the exception of patients with Eisenmenger's syndrome, pulmonary vascular obstructive disease, and Marfan's syndrome with aortopathy, maternal death during pregnancy is rare in women with CHD but morbidity occurs such as heart failure, arrhythmias, and stroke. Echocardiography represents a milestone in diagnosis, understanding of pathophysiology, assessment of disease severity and patient monitoring in pregnant women with unoperated and post-operative congenital heart disease.

In this retrospective study, features of 47 cattle suffering from heart disease (HD) without clinical signs of heart failure (HF) were reviewed. The most common reasons for referral were respiratory problems (n =14), anorexia (n = 13), fever (n = 10), and lameness (n = 9). Thirty-nine animals were tachypneic. In 31 cases, cardiac auscultation revealed abnormalities. The final diagnoses were bacterial endocarditis (BE; n = 19), congenital heart disease (CHD; n = 18), pericarditis (n = 8), cardiomyopathy (n = 1), and lymphoma (n = 1). Echocardiography was performed in 39 cases. Gross pathology examination confirmed the echocardiographic diagnosis in 4 of 5 cases of pericarditis, 6 of 6 cases of BE, and 4 of 6 cases of CHD. Short-term prognosis was guarded with 19 cases (40.4%) being discharged. Premature death within 2 mo after discharge (n = 5), early culling because of poor breeding performance (n = 5), and normal productive life in the herd (n = 5) were observed in the cases that were followed. Echocardiography may be the most sensitive tool for the antemortem diagnosis of heart disease in cattle.

The number of women with congenital heart disease reaching childbearing age is constantly increasing due to the advances achieved in cardiac surgery during the past decades. The significant physiological haemodynamic changes and adaptations of the cardiovascular system associated with pregnancy, birth and puerperium increases the cardiovascular risk to pregnant women with congenital heart disease. It is therefore necessary not only the awareness of these haemodynamic changes and risks, but also a multidisciplinary approach that involves preconception counseling, choosing the best contraceptive method, close surveillance during pregnancy, delivery and puerperium. The purpose of this article is to review the major risks associated with pregnancy in women with CHD and to provide an indication on the best contraceptive method and cares during pregnancy in these patients.

Respiratory syncytial virus (RSV) is a main cause of hospitalization for bronchiolitis and pneumonia in infants worldwide. Children with hemodynamically significant congenital heart disease (HS-CHD), as well as premature infants are at high risk for severe RSV diseases. Mortality rates for CHD patients hospitalized with RSV have been reported as about 24 times higher compared with those without RSV infection. Recently with advances in intensive care, mortality rates in CHD patients combined with RSV have decreased below 2%. The requirements of intensive care and mechanical ventilation for CHD patients with RSV infection were still higher than those without RSV infection or with non-CHD children. RSV infection has frequently threatened CHD infants with congestive heart failure, cyanosis, or with pulmonary hypertension. As a progressive RSV pneumonitis in those infants develops, the impairment of oxygen uptake, the breathing workload gradually increases and eventually causes to significant pulmonary hypertension, even after the operation. Preventing RSV infection as much as possible is very important, especially in infants with HS-CHD. A humanized monoclonal antibody, palivizumab, has effective in preventing severe RSV disease in high-risk infants, and progressive advances in supportive care including pulmonary vasodilator have dramatically decreased the mortality (<1%). Depending on the global trend, Korean Health Insurance guidelines have approved the use of palivizumab in children <1 year of age with HS-CHD since 2009. Korean data are collected for RSV prophylaxis in infants with CHD.
