The optimal timing for pulmonary valve replacement after Tetralogy of Fallot (TOF) repair remains controversial. In this study, we estimated the feasibility of using flow energy loss (FEL) to predict right ventricular (RV) deterioration due to pulmonary regurgitation after TOF repair. We examined RV outflow tract (RVOT) flow in nine patients who underwent TOF or double-outlet right ventricle repair in the intervention group (Group I) and compared them with three healthy children in the control group (Group C)...

PURPOSE: Bowel is often the dose-limiting organ in curative pelvic irradiation because of radiation enteritis when dose exceeds 40 to 45 Gy. To limit radiation enteritis, a silicone tissue-expander prothesis (STEP) connected to a subcutaneous self-sealing valve was prospectively used in children undergoing pelvic or abdominal radiation therapy. This study reports the 15-year long-term outcomes of this prospective series. METHODS AND MATERIALS: Between 1987 and 2008, 29 children from 3 Paris institutions received pelvic radiation therapy after surgical placement of a STEP in the pelvis...

BACKGROUND: Considering the limited accuracy of clinical examination for early diagnosis of rheumatic heart disease (RHD), echocardiography has emerged as an important epidemiological tool. The ideal setting for screening is yet to be defined. We aimed to evaluate the prevalence and pattern of latent RHD in schoolchildren (aged 5-18 years) and to compare effectiveness of screening between public schools, private schools, and primary care centers in Minas Gerais, Brazil. METHODS AND RESULTS: The PROVAR (Rheumatic Valve Disease Screening Program) study uses nonexperts and portable and handheld devices for RHD echocardiographic screening, with remote interpretation by telemedicine, according to the 2012 World Heart Federation criteria...

BACKGROUND: Intraoperative transesophageal echocardiography (iTEE) is used to assess for residual left ventricular outflow tract obstruction (LVOTO) after surgical resection of subaortic membrane causing subaortic stenosis (sub-AS). We aimed to identify the iTEE features associated with recurrence of LVOTO. METHODS: We conducted a retrospective study of children undergoing sub-AS resection from June 2006 to June 2014. Doppler assessment of the flow velocity and the anatomical features of the left ventricular outflow tract were analyzed from stored echocardiograms...

Transcatheter pulmonary valve replacement is now a feasible alternative to surgical pulmonary valve replacement in children and adults with dysfunctional right ventricular outflow conduits. Currently, 2 types of valves can be used for this application. This article provides an overview of the procedure and how it is performed, indications and contraindications for transcatheter pulmonary valve replacement, and short- and long-term outcomes. Nursing considerations mainly focus on educating patients, preventing bleeding and infection, monitoring renal function, and preventing injury to the catheter insertion site...

OBJECTIVE: Clinical decision making in children with heart disease relies on detailed measurements of cardiac structures using two-dimensional and M-mode echocardiography. However, no echocardiographic reference values are available for the Chinese children. We aimed to establish z-score regression equations for left heart structures in a population-based cohort of healthy Chinese Han children. METHOD: Echocardiography was performed in 545 children with a normal heart...

We report the techniques and long-term outcome of mitral valve (MV) repair to correct congenital mitral stenosis in children. Between 1986 and 2014, 137 children (mean age 4.1 ± 5.0, range 1 month-16.8 years) underwent repair of congenital mitral stenosis (CMS). In 48 patients, CMS is involved in Shone's anomaly. The typical congenital MS (type I) was seen in 56 patients. Hypoplastic MV (type II, n = 15) was associated with severe left ventricular outflow tract abnormalities and hypoplastic left ventricular cavity and muscle mass...

Congenital mitral valve (MV) dysplasia is a relatively rare and highly complex cardiac disease. We sought to provide a comprehensive analysis of the current surgical techniques for treating mitral valve insufficiency and the results of mitral valve repair at our institution. Between 1972 and 2017, 104 consecutive patients underwent surgical repair of congenital MV dysplasia-insufficiency at our institution. Among these, 59 patients presented with MV insufficiency (or prevalent MV insufficiency) and were part of the study...

OBJECTIVES: Our goal was to investigate the outcome of the left atrioventricular valve (LAVV) after repair of atrioventricular septal defects (AVSDs) by analysing the mechanisms of LAVV failure. METHODS: A retrospective investigation of 202 children with AVSD, operated on between 1992 and 2016, was performed. Analysis focused on freedom from reoperation for LAVV dysfunction, with specific attention to the modes of failure. RESULTS: The population consisted of 129 (64%) patients with complete AVSD (cAVSD) and 73 (36%) patients with partial AVSD (pAVSD), corrected at a median age of 3...

Spacers offer a multitude of benefits by reducing the requirement to coordinate inhalation with actuation and improving inhaler technique in patients using a pressurized metered dose inhaler (pMDI). Spacers improve drug targeting by retaining within the spacer large particles normally deposited in the oropharynx, and by creating a prolonged aerosol cloud of fine particles to give the user increased time to inhale after actuation. This is particularly important in young children and the elderly to effectively deliver medication to the airways...

Narrow mitral annulus is a common situation faced in adult patients. Choice of prosthetic valve in such cases is unclear. There are reported experiences with supra-annular mitral valve, Manouguian technique, "Chimney technique" with mechanical valve and Melody valve, the latter two being in children. We report a novel "Bio-Chimney" technique in which a bioprosthetic valve of a size appropriate for the patient is sutured to a polyester vascular graft which is then implanted to the native narrow mitral annulus in an adult patient with promising initial results...

BACKGROUND: Stented bioprosthetic valves (BPVs) are commonly used for surgical pulmonary valve (PV) replacement in postoperative congenital heart disease, but develop structural failure in a time-related fashion. The Melody transcatheter PV (TPV) (Medtronic, Minneapolis, Minn) has been used to treat BPV dysfunction, but there have been few studies in this population. METHODS: We performed a retrospective, multicenter study to evaluate Melody valve function in patients who underwent TPV replacement (TPVR) into a dysfunctional pulmonary BPV...

The systemic right ventricle (SRV) is commonly encountered in congenital heart disease representing a distinctly different model in terms of its anatomic spectrum, adaptation, clinical phenotype, and variable, but overall guarded prognosis. The most common clinical scenarios where an SRV is encountered are complete transposition of the great arteries with previous atrial switch repair, congenitally corrected transposition of the great arteries, double inlet right ventricle mostly with previous Fontan palliation, and hypoplastic left heart syndrome palliated with the Norwood-Fontan protocol...

BACKGROUND: Changes in the coagulation system during pregnancy and puerperium produce a physiological hypercoagulable state. These changes are thought to be the cause of the higher rates of deep vein thrombosis, pulmonary embolism, stroke, and mechanical prosthetic valve thrombosis during pregnancy. Thrombolysis can be a treatment option in this cases. However, there are no available data from randomized controlled trials in pregnant patients and information about the security of thrombolytics in pregnancy is missing...

We report the successful surgical treatment of aortic regurgitation in a 27-year-old woman with Turner syndrome (TS) who was admitted with exacerbation of dyspnea on exertion. Echocardiography showed a bicuspid aortic valve with severe aortic regurgitation and computed tomography showed dilatation of the ascending aorta and aortic root. Due to the patient's low body surface area (due to TS), standard determination of aortic size was not possible; therefore, we used the reference curves of aortic diameters in children...

The deployment status of pediatric emergency equipment in ambulances in Japan is unknown. To investigate the status of and issues associated with prehospital emergency medical care for pediatric patients, we conducted a descriptive epidemiological study. We carried out a Web-based survey of 767 fire defense headquarters in Japan, of which 671 responded (valid response rate, 88%). Most of the fire defense headquarters equipped all of their ambulances with oxygen masks (82%), bag-valve masks (for neonates, 83%; for children, 84%), straight laryngoscope blades (for neonates, 47%; for children 68%), blood pressure cuffs for children (91%), oximeter probes (78%), and stiff neck collars (91%); but despite the need for other equipment such as nasopharyngeal and oropharyngeal airways, and Magill forceps, they were insufficiently deployed...

BACKGROUND: Our institutional approach to tetralogy of Fallot (TOF) with major aortopulmonary collaterals (MAPCAs) emphasizes unifocalization and augmentation of the reconstructed pulmonary arterial (PA) circulation and complete intracardiac repair in infancy, usually in a single procedure. This approach yields a high rate of complete repair with excellent survival and low right ventricular (RV) pressure. However, little is known about remodeling of the unifocalized and reconstructed pulmonary circulation or about reinterventions on the reconstructed PAs or the RV outflow tract conduit...
