Weaving is a resourceful technology which offers a large selection of solutions that are readily adaptable for tissue engineering (TE) of artificial heart valves (HV). The different ways that the yarns are interlaced in this technique could be used to produce complex architectures, such as the three-layer architecture of the leaflets. Once the assembly is complete, growth of cells in the scaffold would occur in the orientation of the yarn, enabling the deposition of extra cellular matrixes proteins in an oriented manner...

Ebstein's anomaly is defined as the significant apical displacement of the tricuspid valve causing tricuspid regurgitation. Although a variety of concomitant lesions have been previously described, we herein introduce an unusual presentation. Our patient was an 86-year-old man with a primary presentation of typical chest pain in the setting of recently diagnosed coronary artery disease with concomitant Ebstein's anomaly. We found mild-to-moderate tricuspid regurgitation, bicuspid aortic valve, persistent left superior vena cava, and patent foramen ovale...

Cardiac catheterization has greatly contributed to the progress made in the management of congenital heart diseases (CHD). Initially used in diagnosis, it allowed the understanding of heart diseases, their anatomy and hemodynamics. Gradually, the development of interventional cardiology has played a major role in the management of these malformations (Patent ductus arteriosus [PDA] and atrial septal defect [ASD] closure, pulmonary dilatation, percutaneous pulmonary valve implantation…). The development of such technology was made possible through the concomitant development of imaging techniques: fluoroscopy, ultrasound, MRI and CT...

REVIEW
Elles J Dijkema, Tim Leiner, Heynric B Grotenhuis
Coarctation of the aorta (CoA ) is a well-known congenital heart disease (CHD) , which is often associated with several other cardiac and vascular anomalies, such as bicuspid aortic valve (BAV), ventricular septal defect, patent ductus arteriosus and aortic arch hypoplasia. Despite echocardiographic screening, prenatal diagnosis of C o A remains difficult. Most patients with CoA present in infancy with absent, delayed or reduced femoral pulses, a supine arm-leg blood pressure gradient (> 20 mm Hg), or a murmur due to rapid blood flow across the CoA or associated lesions (BAV)...

REVIEW
Cumara B O'Carroll, Kevin M Barrett
PURPOSE OF REVIEW: Cardioembolic stroke is common and disproportionately more disabling than nonembolic mechanisms of stroke. Its incidence is expected to rise because of the age-related incidence of atrial fibrillation and an aging population. This article summarizes the different causes of cardioembolism and outlines current management guidelines. RECENT FINDINGS: Since cardioembolic stroke is not a single disease entity, its diagnosis requires initial clinical suspicion and a comprehensive evaluation, including ECG, echocardiography, brain imaging, and cardiac monitoring...

INTRODUCTION: Ebstein's anomaly is a benign and stable congenital heart disease for asymptomatic patients. Despite a low incidence of Ebstein's anomaly (EA), patients' quality of life can be badly affected by EA without positive surgical intervention. Especially EA is associated with other congenital heart disease, such as the atrial septal defect, patent foramen ovale, and arterial embolism exclude other reasons, it is often considered to be the consequence of paradoxical embolism, and surgical intervention must be conducted...

Interventional cardiac catheterization has a major place in the management of congenital heart disease. Since the Rashkind atrioseptostomy in mid-1960s, many techniques have been developed. For some, it is necessary to close a cardiac or extracardiac shunt using occluder (double disc system, plug, coil…): closure of atrial septal defect, ventricular septal defect or patent arterial duct. For others, it is necessary to treat a valvular or vascular stenosis using a balloon catheter: dilatation of the pulmonary or the aortic valve, dilatation of aortic coarctation...

Persistent pulmonary artery hypertension (PAH) after balloon mitral valvuloplasty (BMV) is not uncommon, and is generally associated with established pulmonary vascular disease, an inadequate result, or the development of mitral regurgitation. An unfavorable mitral valve morphology with a smaller post-procedural mitral valve area is among the most common causes of the condition. While routine cardiac catheterization is no longer recommended prior to intervention in valvular heart disease, patients with persistent PAH after BMV should undergo a thorough evaluation before they are considered for repeat BMV...

BACKGROUND: The aim of the present study was to evaluate the echocardiographic follow-up of patent foramen ovale, which is considered a potential etiological factor in various diseases, and to determine the factors affecting spontaneous closure. METHODS: Between January 2000 and June 2012, records of 918 patients with patent foramen ovale were retrospectively reviewed. Patency of less than 3 mm around the fossa ovalis is called patent foramen ovale. Patients with cyanotic congenital heart diseases, severe heart valve disorders and severe hemodynamic left to right shunts were excluded from the study...

BACKGROUND: Preoperative hemoglobin A1c (HbA1c) and postoperative glycemic variability predict major adverse events (MAEs) after coronary artery bypass grafting in a protocolized glycemic control setting. However, the influence of preoperative HbA1c and postoperative glycemic variability in isolated cardiac valvular surgery is unknown. In this study, we sought to establish (a) whether preoperative HbA1c could identify patients at increased risk of MAEs and (b) whether postoperative glycemic variability was associated with MAEs after isolated cardiac valvular surgery...

Congenitally unguarded tricuspid valve (TV) orifice, a variant of TV dysplasia, is a rare malformation with protean manifestations. This report describes a symptomatic adult male with gross right heart failure and atrial fibrillation, who was found to have an unguarded TV orifice with isolation of the trabecular apical cavity of the right ventricle (RV) and muscular ridges separating outflow tract (forme-fruste of the double-chambered RV). The right ventricular outflow tract remained patent.

A Schmermund, J Eckert, S N Schelle, H Eggebrecht
For the treatment of structural heart disease, current options in the catheterization laboratory include MitraClip® implantation for treating severe mitral regurgitation, transcatheter aortic valve implantation (TAVI), closure of a patent foramen ovale (PFO) and occlusion of the left atrial appendage (LAA). These treatment options are based on a precise diagnosis provided by modern cardiac imaging, which is indispensable for treatment recommendations. Its importance for supporting the invasive procedures in the catheterization laboratory is less well known...
