pediatric cardiology Echocardiography cardiac catheterization

BACKGROUND: Isolated left upper partial anomalous pulmonary venous connection (PAPVC) via the innominate vein to the right atrium is a rare congenital anomaly. This study was undertaken to determine the efficacy of a modified suprasternal view in transthoracic echocardiography (TTE) for the detection of left upper PAPVC. METHODS: After the incidental diagnosis of left upper PAPVC in our first patient in 2008, we added a modified suprasternal view to all TTEs performed in our pediatric cardiology clinic...

BACKGROUND: Identifying preoperative pulmonary venous obstruction in total anomalous pulmonary venous connection is important to guide treatment planning and risk prognostication. No standardized echocardiographic definition of obstruction exists in the literature. Definitions based on absolute velocities are affected by technical limitations and variations in pulmonary venous return. The authors developed a metric to quantify pulmonary venous blood flow variation: pulmonary venous variability index (PVVI)...

Single ventricle hearts palliated with the Fontan operation present complications later in life as a result of increased venous pressures and abnormal ventricle function. Wave intensity analysis uses measurements of blood velocity and pressure to represent arterial hemodynamics as summations of energy waves. This methodology could potentially be a useful tool in assessment of Fontan patients. The clinical value of wave intensity parameters was utilized to evaluate the functional performance of the single ventricle in Fontan patients...

BACKGROUND: Coronary cameral fistula (CCF), a rare abnormal coronary communication to cardiac chambers, may lead to coronary steal phenomenon and increase cardiac overload. We investigated the clinical and cardiovascular characteristics in children before and after transcatheter closure. METHODS: We retrospectively reviewed pediatric patients with CCFs diagnosed by echocardiography in a tertiary medical center between 1998 and 2019. Basic information, echocardiogram, catheterization and interventional procedures were obtained from medical charts...

Background Atrial septal defect secundum (ASD II) is the commonest of the congenital heart diseases in the adult population and the closure of ASD II causes a significant improvement in hemodynamics and the clinical status of the patient. However, it carries certain risks, especially the development of post-closure pulmonary edema and congestive cardiac failure, which may lead to death. Therefore, this study was designed to share our experience and to evaluate the immediate and short-term outcomes of percutaneous closure of ASD II in adult patients presenting at a tertiary care cardiac center in Karachi, Pakistan...

Objective: To explore the risk factors for death in patients with pulmonary arterial hypertension related to congenital heart disease (PAH-CHD) and the clinical characteristics of different subtypes in patients with PAH-CHD. Methods: It was a retrospective study. A total of 507 PAH-CHD patients, who were hospitalized in the Department of Pediatric Cardiology of Beijing Anzhen Hospital between September 2005 and May 2019, were included. Patients were divided into 4 subgroups: (1) Eisenmenger syndrome(ES) group...

The European Pediatric Pulmonary Vascular Disease Network is a registered, non-profit organization that strives to define and develop effective, innovative diagnostic methods and treatment options in all forms of pediatric pulmonary hypertensive vascular disease, including pulmonary hypertension (PH) associated with bronchopulmonary dysplasia, PH associated with congenital heart disease (CHD), persistent PH of the newborn, and related cardiac dysfunction. The executive writing group members conducted searches of the PubMed/MEDLINE bibliographic database (1990-2018) and held face-to-face and web-based meetings...

Objectives: To identify the pattern of un-operated grown up congenital heart defects at our tertiary care cardiac institute. Methods: This is a prospective observational study. All un-operated GUCH patients who presented to Faisalabad Institute of Cardiology (FIC) from May 2017 to 30th July 2017 were enrolled. Diagnosis was established on Transthoracic Echocardiography done by dedicated pediatric cardiologist at FIC. The mode of presentation, presenting complaints, type, severity, complications and co-morbid conditions of CHD were recorded...

Cardiac imaging is central to today's pediatric cardiology practice not only to diagnose structural congenital defects and delineate cardiac and extracardiac anatomy but also for determining the hemodynamic impact of the structural defects and acquired pediatric diseases. Not so long ago, clinicians had to heavily rely on angiography as the main cardiac imaging modality to visualize the heart. Particularly, the development of echocardiography in the 1970s and 1980s together with the development of magnetic resonance imaging (MRI) and computed tomography (CT) resulted in a non-invasive diagnostic revolution with diagnostic catheterization becoming obsolete apart for very specific indications...

BACKGROUND: Fontan-associated liver disease (FALD) is an important late complication involving liver dysfunction, such as liver cirrhosis (LC) and hepatocellular carcinoma (HCC), in patients undergoing the Fontan procedure. However, the prevalence, clinical manifestation, and methods of diagnosis of FALD are still not well established.Methods and Results:This study comprised 2 nationwide surveys in Japan. First, the prevalence of LC and/or HCC in patients undergoing the Fontan procedure was determined...

OBJECTIVE: Congenital cardiac malformations with high pulmonary blood flow and pressure due to left-to-right shunts are usually repaired in early infancy for both the benefits of early relief of heart failure and the fear that the concomitant pulmonary hypertension may become irreversible unless these defects are corrected at an early age. Age, however, has been a poor predictor of irreversibility of pulmonary hypertension in our experience, which is presented here. DESIGN: A retrospective observational study...

During the last 10 years, there have been major technological achievements in pediatric interventional cardiology. In addition, there have been several advances in cardiac imaging, especially in 3-dimensional imaging of echocardiography, computed tomography, magnetic resonance imaging, and cineangiography. Therefore, more types of congenital heart diseases can be treated in the cardiac catheter laboratory today than ever before. Furthermore, lesions previously considered resistant to interventional therapies can now be managed with high success rates...

This study aims to review pediatric pulmonary hypertension (PH) by comparing the guidelines of the European Society of Cardiology (ESC)/European Respiratory Society (ERS), the American Heart Association (AHA)/American Thoracic Society (ATS), and the European Pediatric Pulmonary Vascular Disease Network (EPPVDN). All three sets of guidelines define PH as having a mean pulmonary artery pressure of ≥25 mmHg and accept the validity of the World Health Organization (WHO) classification system. Every child with a high index of suspicion for PH should undergo an initial work-up of chest X-rays, electrocardiography, and echocardiography...

The transition from residency to subspecialty fellowship in a procedurally driven field such as pediatric cardiology is challenging for trainees. We describe and assess the educational value of a pediatric cardiology "boot camp" educational tool designed to help prepare trainees for cardiology fellowship. A two-day intensive training program was provided for pediatric cardiology fellows in July 2015 at a large fellowship training program. Hands-on experiences and simulations were provided in: anatomy, auscultation, echocardiography, catheterization, cardiovascular intensive care (CVICU), electrophysiology (EP), heart failure, and cardiac surgery...

PURPOSE: Transesophageal echocardiography (TEE) has a pivotal role in invasive cardiology practice in terms of guiding a variety of procedures. It is challenging to perform TEE examination with sedated patients due to difficulties in cooperation and positioning the patient properly, therefore the risk of complications is escalated. We aimed to assess the impact of pediatric TEE probe utilization on procedural success and complication rates; in comparison with conventional adult TEE probe...

Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart defect. We explore "hot topics" to highlight areas of emerging science for clinicians and scientists in moving toward a better understanding of the long-term management of patients with repaired TOF. From a genetic perspective, the etiology of TOF is multifactorial, with a familial recurrence risk of 3%. Cardiac magnetic resonance is the gold standard assessment tool based on its superior imaging of the right ventricular (RV) outflow tract, pulmonary arteries, aorta, and aortopulmonary collaterals, and on its ability to quantify biventricular size and function, pulmonary regurgitation (PR), and myocardial viability...

Interventional cardiac catheterization in children and adolescents is traditionally performed with the patient under general anesthesia and endotracheal intubation. However, percutaneous closure of atrial septum defect (ASD) without general anaesthesia is currently being attempted in a growing number of children. The study objective was to evaluate the success and complication rate of percutaneous ASD closure in spontaneously breathing children under deep sedation. Retrospective single centre cohort study of consecutive children undergoing percutaneous ASD closure at a tertiary care pediatric cardiology centre...

BACKGROUND AND AIMS: Percutaneous implantation of pulmonary valve has been recently introduced in the clinical practice. Our aim was to analyze data of patients treated in Italy by using the Melody Medtronic valve. METHODS: Prospective, observational, multi-centric survey by means of a web-based database registry of the Italian Society of Pediatric Cardiology (SICP). RESULTS: Between October 2007 and October 2010, 63 patients were included in the registry (median age: 24 years; range 11-65 years)...

The initial success seen in adult cardiac surgery with the application of available robotic systems has not been realized as broadly in pediatric cardiac surgery. The main obstacles include extended set-up time and complexity of the procedures, as well as the large size of the instruments with respect to the size of the child. Moreover, while the main advantage of robotic systems is the ability to minimize incision size, for intracardiac repairs, cardiopulmonary bypass is still required. Catheter-based interventions, on the other hand, have expanded rapidly in both application as well as the complexity of procedures and lesions being treated...

Several techniques have been applied for the assessment of severe congenital heart diseases (SCHD) including echocardiography, cardiac catheterization with angiocardiography, and more recently, cardiovascular multi detector tomography and magnetic resonance imaging (MRI). The value of gated single photon emission tomography (GSPET) myocardial perfusion imaging (MPI) and radionuclide ventriculography (RNV) for evaluating myocardial ischemia, tissue viability, and left ventricular function in SCHD is less apparent...
