OBJECTIVES: Ultra-high-molecular-weight polyethylene (UHMWPE) fibres are flexible, have high tensile strength, and platelet and bacterial adhesion is low. Therefore, UHMWPE may overcome limitations of current mechanical valves and bioprostheses. In this study, the biocompatibility and functionality of prototype handmade stented valves from woven UHMWPE (U-valve) was assessed in a chronic sheep model with acetylsalicylic acid monotherapy. METHODS: Native pulmonary valves of 23 sheep were replaced by U-valves ( n  = 18) or Perimount bovine bioprostheses (reference group, n  = 5)...

Chronic pulmonary insufficiency following transannular patch repair of tetralogy of Fallot may mandate restoration of a competent pulmonary valve. Pulmonary valve leaflets that are preserved at initial surgery may grow and develop normal morphology and subsequent valve repair may be possible. We reviewed our experience with native pulmonary valve restitution following transannular patch repair (2001-15). The cohort included 9 patients with a median age of 18.7 (range 10.6-31.3) years. Operative technique involved reapproximation of the anterior commissure of the pulmonary valve...

OBJECTIVE: To investigate the clinical usefulness of echocardiography in the diagnosis of infracardiac total anomalous pulmonary venous connection (ITAPVC) in neonates and infants. METHODS: Retrospective analysis on 8 patients with ITAPVC was performed using echocardiography between April 2006 and December 2016. There were 4 boys and 4 girls with a mean age of 79.8 days (ranging from 15 to 195 days). A combined scanning via parasternal, subcostal and apical acoustic windows had been employed to diagnose ITAPVC and to trace the course and site of the anomalous pulmonary venous drainage, and to confirm the direction of the inter-atrial shunt and enlargement of right atrium and right ventricle...

To explore the accuracy of main pulmonary artery (MPA) and ascending aorta (AAO) image evaluation in pediatric patients with single ventricle (SV) by comparing dual-source computed tomography (DSCT) with echocardiography. Thirty-one children with SV were retrospectively enrolled. The stenosis, dilation, and location of MPA and AAO were independently evaluated by DSCT and echocardiography. The accompanying arterial malformations were also assessed by DSCT. For 17 patients undergoing cardiac catheterization, the DSCT-based diameters of MPA and AAO were correlated with their pressures as measured by catheterization...

The case of an 11-year-old male patient with truncus arteriosus is presented. The patient has a right aortic arch, a repaired truncus arteriosus, pulmonary artery stenosis, as well as conduit stenosis, with a complex surgical plan being discussed. In order to gather additional insight into the patient's anatomy prior to the surgery and to facilitate communication with the patient's parents, a three-dimensional (3D) model of his heart and main vessels was created from computed tomography data. Feedback was collected from different stakeholders...

Endoscopic variceal sclerotherapy and ligation are standard treatment modalities used for the management of esophageal varices. Reportedly, sclerotherapy and ligation are associated with complications such as hematuria, pulmonary thrombus formation, pleural effusion, renal dysfunction, and esophageal stenosis. However, hemothorax following sclerotherapy and ligation has not yet been reported. We treated a patient who presented with liver cirrhosis and polycythemia vera and later developed hemothorax following the above-mentioned procedures...

INTRODUCTION AND OBJECTIVES: Transcatheter aortic-valve implantation (TAVI) is an accepted treatment for patients with severe aortic stenosis and high surgical risk. However, there is lack in data about TAVI in low-risk patients that are already being treated with this therapy in some clinical contexts. METHODS: A retrospective analysis of patients treated with transfemoral TAVI using Edwards Sapien prosthesis in one center was performed, classifying the patients into three groups according to the surgical risk (high/intermediate/low risk for STS score>8/4-8/<4)...

Aims: Treatment decisions in patients with scimitar syndrome (SS) are often challenging, especially in patients with isolated SS who are often asymptomatic and who might be diagnosed accidentally. We queried a large multi-institutional registry of SS patients to evaluate the natural history of this condition and to determine the efficacy of surgical treatment in terms of survival and clinical status. Methods and results: We collected data on 485 SS patients from 51 institutions; 279 (57%) patients were treated surgically (STPs) and 206 (43%) were clinically monitored (CMPs)...

Objectives A main problem with bioprosthesis used for surgical correction of congenital cardiac malformation is their tendency to shrink and to calcify. Recently, a new material i.e. de-cellularised bovine pericardium (CardioCel(®)) was introduced in clinics. It was proposed that this new patch material should not calcify and should be particularly suitable for the correction of vascular defects in inborn cardiac diseases. The aim of our chronic minipig study was to evaluate the performance of CardioCel(®) patches implanted in aortic and pulmonary artery position, respectively...

Aims: In patients with aortic stenosis (AS), risk stratification for aortic valve replacement (AVR) relies mainly on valve-related factors, symptoms and co-morbidities. We sought to evaluate the prognostic impact of a newly-defined staging classification characterizing the extent of extravalvular (extra-aortic valve) cardiac damage among patients with severe AS undergoing AVR. Methods and results: Patients with severe AS from the PARTNER 2 trials were pooled and classified according to the presence or absence of cardiac damage as detected by echocardiography prior to AVR: no extravalvular cardiac damage (Stage 0), left ventricular damage (Stage 1), left atrial or mitral valve damage (Stage 2), pulmonary vasculature or tricuspid valve damage (Stage 3), or right ventricular damage (Stage 4)...

Obstruction of the superior vena cava (SVC) is an uncommon, but potentially life-threatening condition due to likely development of edema in the head and neck and potential respiratory compromise. Less than half of those affected by SVC syndrome survive more than a year. Obstruction can be from neoplasms or secondary to benign disease. Treatment for most cases of symptomatic SVC syndrome involves placement of a stent to relieve the stenosis. Serious complications such as stent migration, pulmonary embolism, and cardiac tamponade can occur in 5% to 10% of cases, and inadequate imaging of the SVC-atrial junction by fluoroscopy contributes to these problems...
