    Major developments in diagnostic techniques in pre- and neonatal care have significantly reduced the rate of undetected congenital heart defects (CHD). Despite such advances, several patients with critical congenital heart defects are discharged annually from neonatal units with no proper diagnosis or treatment. We present the case of a two month-old originally asymptomatic girl who represents the perfect example of such a situation. The infant was diagnosed just after pulmonary and cardiovascular decompensation with critical, complex CHD. The absence of disease symptoms of occurred due to a rare and specific morphology of pulmonary vessels and intracardiac membranes.Ogromny rozw贸j technik diagnostycznych w opiece przed- i oko艂oporodowej znacz膮co zmniejszy艂 odsetek pacjent贸w z przeoczon膮 wrodzon膮 wad膮 serca.

    Background: Pulmonary artery stenting without a long vascular sheath has a special significance, particularly for children with low body weight. Using only a short sheath often permits the implantion of a stent of the correct size; moreover, it improves access to peripherally located stenoses. The aim of this paper is to present the results of a balloon expandable stent implantation into pulmonary arteries without using a long vascular sheath. Methods: The subjects were divided into two groups. The first group (28 patients, mean age 3.2 years) comprised patients with a single-ventricle heart after bi-directional Glenn procedure (Fontan procedure). The second group (22 patients, mean age 8.3 years) consisted of patients with a two-ventricle heart. Patients were retrospectively analyzed with regard to stenosis size widening and change in trans-stenotic pressure gradient after stenting. Results: In our data, no statistically significant differences between the two groups in terms of the number of complications and incorrect stent position following implantation were noted (3% and 4%). Good treatment results, with a decrease in trans-stenotic pressure gradient in the first group of 3.2 mm and in the second group of 13.4 mm of mercury, and a widening of the stenosis, were obtained in most cases in both groups (97% and 96%). The average change of the vessel’s diameter was in the first group 4.2 mm and in the second 5.4 mm. Conclusions: The obtained results suggest that pulmonary artery stenting with a short vascular sheath has numerous advantages and can be successfully performed in children. In the case of single-ventricle hearts after a Glenn procedure, it may indeed be the method of choice. (Cardiol J 2010; 17, 2: 149-156

    We report a case of a 19-year-old patient with double outlet right ventricle (RV) and recurrent giant RV outflow tract pseudoaneurysm, after multiple redo surgery. The patient underwent implantation of a 10 mm Amplatzer Septal Occluder to close the pseudoaneurysm. Postinterventional echocardiography revealed dislocation of the device into the cavity of the pseudoaneurysm. Consecutive computed tomography enabled three-dimensional measurements of the pseudoaneurysmand its orifice and resulted in implantation of a 20 mm occluder

    Introduction : Creation of a fenestration during completion of a total cavo-pulmonary connection (TCPC) has been associated with a reduction in early mortality and morbidity. However, the long-term benefits are negated by an associated limitation in exercise tolerance and the potential risks of thrombo-embolic complications. We sought to describe the safety and efficacy of an Amplatzer Duct Occluder II (ADO II) for transcatheter fenestration closure following TCPC. Material and methods : Between January 2000 and July 2014, 102 patients underwent percutaneous closure of extra-cardiac TCPC fenestrations with a range of devices. Patients in whom fenestration closure was performed with an ADO II and who had at least 6 months of follow-up were included in this study. Results : Forty-seven patients had successful fenestration occlusion with an ADO II. The mean oxygen saturation and mean systemic venous pressures increased from 84.8 卤6.1% before to 97.6 卤2.9% (p < 0.001) after and from 14.2 卤2.15 mm Hg before to 15.6 卤2.2 mm Hg after closure (p < 0.001). Eight patients developed heart failure symptoms, managed by optimization of medical therapy, with 1 patient requiring device removal to reopen the fenestration. Color Doppler transthoracic echocardiography demonstrated residual flow across the device in 18 (38%), 10 (22%), 5 (11%) and 4 (9%) patients before discharge, at 1 and 6 months, and at the latest outpatient visit, respectively. Conclusions : The ADO II can be safely and effectively used to close fenestrations in extra-cardiac type Fontan completions. Many of the design features of this device confer potential benefit in this population

    AbstractObjectivesThe purpose of this paper is to report our 10 years of experience of interventional treatment of patients with hypoplastic left heart syndrome and to focus on the frequency, type, and results of percutaneous interventions during all the stages of palliation, considering the different techniques, devices, and complications.BackgroundConstant progress in surgical treatment of congenital heart defects in the last decade has significantly improved the prognosis for children with hypoplastic left heart syndrome. However, morbidity and mortality remain relatively high. Modern interventional procedures complement or occasionally replace surgical treatment.MethodsBetween January, 2001 and December, 2010, 161 percutaneous interventions were performed in 88 patients with hypoplastic left heart syndrome. Patients were divided into four groups: (a) before the first surgical treatment including hybrid approach, (b) after first-stage Norwood operation, (c) after second-stage bidirectional Glenn operation, and (d) after third-stage Fontan operation.ResultsPercutaneous interventions resulted in statistically significant changes in pulmonary artery pressures, vessel diameters, and O2saturation. Complications occurred in 4.3% of interventions and were related mainly to stent implantation in stenosed pulmonary arteries.ConclusionsPercutaneous interventions may result in haemodynamic stability and reduction in the number of operations. They may result in significant changes in pulmonary artery pressures, vessel diameters, O2saturation, with a low rate of complications, which are mainly related to stent implantation in the pulmonary arteries.</jats:sec

    Background: Presence of a restrictive interatrial communication in patients with univentricular anatomy significantly affects surgical outcomes. In patients with univentricular hearts, wide open atrial communication leads to lower pulmonary artery pressure, which is one of the most important factors influencing the success of bidirectional Glenn and Fontan operations. In some patients, recurrence of restricted interatrial communication can be observed despite initially successful interventional or surgical creation of unrestrictive interatrial communication. Aim: To evaluate efficacy of stent implantation into the interatrial septum in patients with univentricular heart and a secondary restriction of interatrial communication. Methods: In 2006&#8211;2010, we created unrestrictive interatrial communication by stent implantation into the interatrial septum in 7 children with univentricular anatomy with systemic right ventricle (4 patients with hypoplastic left heart syndrome and 3 patients with mitral atresia). In all patients we diagnosed recurrent restriction of interatrial communication despite prior surgical or interventional creation of unrestrictive interatrial communication. Patient age at stent implantation was 3 to 30 months. Maximal systolic pressure gradient between the left and the right atrium was 6&#8211;29 mm Hg and left atrial pressure ranged from 20/17/19 mm Hg to 40/29/32 mm Hg. In all patients, we implanted a Palmaz-Genesis stent (length 18&#8211;29 mm) with subsequent balloon redilatation. Results: In all 7 patients, we created unrestrictive interatrial communication with mean pressure gradient reduction from 13.14 mm Hg to 0.86 mm Hg (p < 0.006). Mean interatrial communication diameter increased from 4.14 mm to 10.57 mm (p < 0.0001). Conclusions: Percutaneous stent implantation into the interatrial septum in children with univentricular heart and secondary restriction of interatrial communication is a safe and effective method.

W tej grupie pacjent贸w szerokie po艂膮czenie mi臋dzyprzedsionkowe prowadzi do obni偶enia ci艣nienia w t臋tnicy p艂ucnej, kt贸re jest jednym z najwa偶niejszych czynnik贸w warunkuj膮cych pomy艣lny przebieg zabiegu dwukierunkowego zespolenia sposobem Glenna i operacji Fontana. U niekt贸rych os贸b, mimo skutecznego, interwencyjnego (zabieg Rashkinda) lub operacyjnego wytworzenia swobodnej komunikacji mi臋dzyprzedsionkowej, wyst臋puje nawr贸t restrykcji na poziomie przegrody mi臋dzyprzedsionkowej. Cel: Celem pracy by艂a ocena skuteczno艣ci i bezpiecze艅stwa implantacji stent贸w do przegrody mi臋dzyprzedsionkowej u pacjent贸w z czynno艣ciowo pojedyncz膮 komor膮, u kt贸rych dosz艂o do wt贸rnej restrykcji po艂膮czenia mi臋dzyprzedsionkowego. Metody: W latach 2006&#8211;2010 wykonano 7 zabieg贸w przezsk贸rnego poszerzenia po艂膮czenia mi臋dzyprzedsionkowego z implantacj膮 stent贸w. Pod wzgl臋dem hemodynamicznym pacjenci reprezentowali serce czynno艣ciowo jednokomorowe, z systemow膮 komor膮 praw膮 (4 dzieci z zespo艂em niedorozwoju lewego serca, 3 pacjent贸w z atrezj膮 zastawki dwudzielnej). U wszystkich chorych narastanie restrykcji obserwowano mimo wcze艣niejszego interwencyjnego lub operacyjnego wytworzenia swobodnego po艂膮czenia mi臋dzyprzedsionkowego. Wiek dzieci w czasie implantacji stentu wynosi艂 3&#8211;30 miesi臋cy, maksymalny gradient ci艣nienia na poziomie restrykcyjnego po艂膮czenia &#8212; 6&#8211;29 mm Hg, a warto艣膰 ci艣nienia w lewym przedsionku &#8212; od 20/17/19 mm Hg do 40/29/32 mm Hg. Wszystkim pacjentom implantowano stenty Palmaz-Genesis (d艂ugo艣膰 18&#8211;19 mm). Wyniki: W grupie 7 pacjent贸w ze stentem implantowanym do przegrody mi臋dzyprzedsionkowej uzyskano obni偶enie warto艣ci gradientu lewo-prawego ze 艣rednio 13,14 mm Hg do 0,86 mm Hg (p < 0,006). Uzyskano tak偶e poszerzenie 艣rednicy po艂膮czenia mi臋dzyprzedsionkowego ze 艣rednio 4,14 mm do 10,57 mm (p < 0,0001). Wnioski: Przezsk贸rna implantacja stentu do przegrody mi臋dzyprzedsionkowej u dzieci z hemodynamicznie wsp贸ln膮 komor膮 skutecznie eliminuje wt贸rn膮 restrykcj臋 po艂膮czenia mi臋dzyprzedsionkowego, pozwalaj膮c na dekompresj臋 lewego przedsionka; zmniejsza r贸wnie偶 konieczno艣膰 dodatkowego leczenia operacyjnego. Stent implantowany do przegrody mi臋dzyprzedsionkowej mo偶e by膰 w prosty spos贸b usuni臋ty podczas kolejnego etapu leczenia operacyjnego. U pacjent贸w z czynno艣ciowo pojedyncz膮 komor膮 i wt贸rn膮 restrykcj膮 po艂膮czenia mi臋dzyprzedsionkowego implantacja stentu stanowi skuteczn膮 i bezpieczn膮 metod臋 terapii.
