To determine the early results of balloon expandable stent implantation for aortic coarctation or recoarctation.Prospective observational study.Two paediatric cardiology tertiary referral centres.17 patients, median age 17 years (range 4.4 to 45) and weight 61 kg (17 92). Six had native 11 recoarctation; 14 upper limb systolic hypertension. Of those with recoarctation, eight at least one previous dilatation attempt two these patients also further surgical interventions.Balloon Palmaz iliac...

We inserted covered Cheatham-Platinum stents in 4 patients, ranging age from 12 to 19 years, who weighed between 45 and 94 kg. All the patients had aortic coarctation, with surgical repair having been attempted previously one, balloon dilation performed as primary treatment two, resulting formation of aneurysms.

Abstract Background The clinical significance of isolated systolic hypertension with normal central blood pressure known as spurious (sHT) in adolescents and its evolution over time is not known. Methods aim this study was to analyze changes office, ambulatory (ABPM), (cSBP), hemodynamic parameters, target organ damage (TOD) a 1-year follow-up group non-obese children sHT. Results Of 294 patients referred for primary hypertension, 138 (31 girls; 22%) had confirmed by ABPM. 48/138 (35%) (7...

Abstract: The modified Blalock–Taussig shunt is a palliative operation for some congenital heart diseases. An artificial conduit with antithrombotic surface placed between the subclavian (or innominate) and pulmonary artery supplies blood to lungs in defects decreased flow. Clotting of graft main cause its failure. Stenosis arteries also observed. objective present study was investigate flow pattern possibility that clotting initiated by stimulation platelets high shear stress, possible...

Background: A Fontan-type operation, i.e. a connection of the systemic veins and pulmonary arteries without subpulmonaryventricle, with different surgical techniques, is nowadays only treatment option for patients functionally univentricularheart (UVH). Understanding development in who are considered Fontanprocedure important clinically. Aim: To evaluate univentricular circulation. Methods: Between 1995 2007, 111 underwent bidirectional Glenn procedure. In all patients,...

Background: The growing number of adults patients after the Fontan operation requires regular surveillance tests in specialized centers. Aims: Evaluation current practice care for Poland based on a multicenter survey. Methods: Eight centers were included study-5 adult congenital heart disease (ACHD) and 3 pediatric adolescents. To aim comparison between facilitate interpretation results, Surveillance Score (FSS) was developed. higher score is consistent with better care, maximum 19 points....

Atrial septal defect is the most common congenital heart lesion in adults. Although atrial closure recommended those with right enlargement or paradoxical embolism, data informing such indications adults are quite limited. This population has many unique characteristics and needs. In recent years, significant progress been made regard to diagnostic modalities that facilitate workup of these patients. However, decision‑making process, especially selected adult patients (advanced age, various...
