BACKGROUND: Drugs acting on the cardiovascular and central nervous system often display relatively fast clinical responses, which may differ in neonates compared to children and adults. Introduction of bedside monitoring tools might be of additional value in the pharmacodynamic (PD) assessment of such drugs in neonates. METHODS: We aim to provide an overview of the frequently used monitoring tools to assess drug effects on the hemodynamic status as well as the cerebral circulation, oxygenation and cerebral metabolism in neonates...

BACKGROUND: Duodenal atresia (DA) is associated with cardiac defects that may have perioperative care implications. Standard preoperative care includes echocardiography to identify such cardiac defects, but this dogma has been challenged. We aimed to assess selective and selective strategies for preoperative echocardiography in DA patients. METHODS: Single-center retrospective review of neonates with DA over a 16-year period was performed. Data included preoperative cardiovascular and respiratory examination, chest x-ray, and echocardiography...

Bronchopulmonary dysplasia (BPD) is a form of chronic lung disease in premature infants following respiratory distress at birth. With increasing survival of extremely low birth weight infants, alveolar simplification is the defining lung characteristic of infants with BPD, and along with pulmonary hypertension, increasingly contributes to both respiratory morbidity and mortality in these infants. Growth restricted infants, infants born to mothers with oligohydramnios or following prolonged preterm rupture of membranes are at particular risk for early onset pulmonary hypertension...

Hypertension-induced left ventricular hypertrophy (LVH) is an independent risk factor for heart failure. Regression of LVH has emerged as a major goal in the treatment of hypertensive patients. Here, we tested our hypothesis that the valosin-containing protein (VCP), an ATPase associate protein, is a novel repressor of cardiomyocyte hypertrophy under the pressure overload stress. Left ventricular hypertrophy (LVH) was determined by echocardiography in 4-month male spontaneously hypertensive rats (SHRs) vs. age-matched normotensive Wistar Kyoto (WKY) rats...

BACKGROUND: Patent ductus arteriosus (PDA) ligation is usually performed by congenital cardiac surgeons. However, due to the uneven distribution of congenital cardiac surgeons in South Korea, many institutions depend solely on adult cardiac surgeons for congenital cardiac diseases. We report the outcomes of PDA ligations performed by adult cardiac surgeons at our institution. METHODS: The electronic medical records of 852 neonates at Chung-Ang University Hospital, Seoul, South Korea from November 2010 to May 2014 were reviewed to identify patients with PDA...

INTRODUCTION: Pierre Robin syndrome is a congenital condition of facial abnormalities in humans. The three main features are: cleft palate, retrognathia and glossoptosis. Rarely heart tumors are associated with syndromes, mostly are isolated. CASE REPORT: In this presentation we describe a 3-weeks-old girl with Pierre-Robin syndrome and giant left ventricle tumor, diagnosed initially by transthoracic echocardiography. The purpose of this report is to review the literature on the fetuses and neonates with cardiac tumors in an attempt to determine the various ways which cardiac tumors differ clinically and morphologically in this age group...

OBJECTIVE: To evaluate the implementation of early screening for critical congenital heart defects (CCHDs) in the neonatal intensive care unit (NICU) and potential exclusion of sub-populations from universal screening. STUDY DESIGN: Prospective evaluation of CCHD screening at multiple time intervals was conducted in 21 NICUs across five states (n=4556 infants). RESULTS: Of the 4120 infants with complete screens, 92% did not have prenatal CHD diagnosis or echocardiography before screening, 72% were not receiving oxygen at 24 to 48 h and 56% were born ⩾2500 g...

Intrauterine growth restriction in animal models reduces heart size and cardiomyocyte number at birth. Such incomplete cardiomyocyte endowment is believed to increase susceptibility toward cardiovascular disease in adulthood, a phenomenon referred to as developmental programming. We have previously described a mouse model of impaired myocardial development leading to a 25% reduction of cardiomyocyte number in neonates. This study investigated the response of these hypoplastic hearts to pressure overload in adulthood, applied by abdominal aortic constriction (AAC)...

Adenylyl cyclase type 9 (AC9) is found tightly associated with the scaffolding protein Yotiao and the IKs ion channel in heart. But apart from potential IKs regulation, physiological roles for AC9 are unknown. We show that loss of AC9 in mice reduces less than 3% of total AC activity in heart but eliminates Yotiao-associated AC activity. AC9(-/-) mice exhibit no structural abnormalities but show a significant bradycardia, consistent with AC9 expression in sinoatrial node. Global changes in PKA phosphorylation patterns are not altered in AC9(-/-) heart, however, basal phosphorylation of heat shock protein 20 (Hsp20) is significantly decreased...

Depression is generally treated with antidepressants, but may often need antipsychotics and mood stabilizers. We discuss the updated data regarding the safety in pregnancy of antidepressants and antipsychotics, except selective serotonin reuptake inhibitors, and their possible impact on the long-term development of the offspring. Several earlier studies demonstrated a slight increase in the rate of major anomalies following maternal tricyclic antidepressant treatment, but most current literature shows their relative safety in pregnancy...

BACKGROUND AND PURPOSE: Perinatal stroke, including neonatal and presumed perinatal presentation, represents the age in childhood in which stroke occurs most frequently. The roles of thrombophilia, arteriopathy, and cardiac anomalies in perinatal ischemic stroke are currently unclear. We took a uniform approach to perinatal ischemic stroke evaluation to study these risk factors and their association with recurrent stroke. METHODS: We reviewed records of perinatal stroke patients evaluated from August 2008 to February 2016 at a single referral center...

REVIEW
Hyun Suk Yang
Congenital heart disease (CHD) is now more common in adults than in children due to improvements in fetal echo, neonatal and pediatric care, and surgical techniques leading to dramatically increased survivability into adulthood. Adult patients with CHD, regardless of prior cardiac surgery, experience further cardiac problems or therapeutic challenges; therefore, a non-invasive, easily accessible echocardiographic examination is an essential follow-up tool. Among echocardiographic modalities, three-dimensional (3D) echocardiography provides better delineation of spatial relationships in complex cardiac geometries and more accurate volumetric information without geometric assumptions...

Here we report a case of fetal left ventricular non-compaction cardiomyopathy with ascites and cardiac dysfunction at a gestational age of 34(+5)  weeks. Laboratory tests did not reveal any sign of viral infection in utero. A female neonate weighing 2436 g was delivered by emergency cesarean section due to non-reassuring fetal status. Postnatal echocardiography confirmed left ventricular non-compaction cardiomyopathy with severe cardiac failure. Although she was treated effectively during the acute period by continuous flow peritoneal dialysis, surgical ligation of a patent ductus arteriosus, and inhaled nitric oxide, she died on day 41 of life...
