Quadricuspid aortic valve (QAV) is a rare congenital heart disease. The functional status of QAV is predominantly a pure aortic regurgitation. Clinical manifestations of patients with a QAV depend on the functional status of the QAV and the associated disorders. Significant valvular regurgitation and (or) stenosis is often present with subsequent operation performed at the fifth to sixth decade of life. The functional status of QAV is predominantly regurgitant; whereas pure stenotic QAV can be as few as in only 0...

A 32-year-old pregnant woman, diagnosed with Behçet's disease 6 months earlier, presented with recent mild hemoptysis and exertional dyspnea. Transthoracic echocardiography showed an enlarged dysfunctional right ventricle. A large hypoechoic triangular-shaped mass was seen attached to the inner right ventricular wall, filling the cavity. No change in the size of the mass was noted after anticoagulant administration, and right heart failure progressed. Surgery was performed to remove the mass and repair the tricuspid valve...

The recent technical advances allow the use in practice of three-dimensional echocardiography in children especially through the new high frequency matrix probe. It is difficult or even impossible to hold breathing during children' acquisition so to avoid motion full volume artifact, one beat and live 3D modes are suitable. 3D echocardiography is more accurate than 2D to assess the size, location, and relationship with surrounding structures of atrial and ventricular septal defects and thus helps in the therapeutic decision...

Cardiac tissue engineering using biomaterials with or without combination of stem cell therapy offers a new option for repairing infarcted heart. However, the bioactivity of biomaterials remains to be optimized because currently available biomaterials do not mimic the biochemical components as well as the structural properties of native myocardial extracellular matrix. Here we hypothesized that human heart valve-derived scaffold (hHVS), as a clinically relevant novel biomaterial, may provide the proper microenvironment of native myocardial extracellular matrix for cardiac repair...

We evaluated the long-term outcomes following repair of truncus arteriosus (TA) from a single institution. We conducted a retrospective review of children (n = 171) who underwent TA repair between 1979 and 2014. Early mortality rate was 11.7% (20/171). There were 19 late deaths. Most deaths (74%, 29/39) occurred within the first year following surgery. The 1-year mortality rate in 1979-2004 was 18% (25/136) and decreased to 11% (4/35) in 2005-2014. The overall survival rate was 73.6% at 30 years. Multivariate analysis identified postoperative extracorporeal membrane oxygenation (P = 0...

BACKGROUND: Symptomatic mitral regurgitation (MR) is associated with high morbidity and mortality that can be ameliorated by surgical valve repair or replacement. Despite this, many patients with MR do not undergo surgery. Transcatheter mitral valve replacement (TMVR) may be an option for selected patients with severe MR. OBJECTIVES: This study aimed to examine the effectiveness and safety of TMVR in a cohort of patients with native valve MR who were at high risk for cardiac surgery...

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...

The function of the heart valve interstitial cells (VICs) are intimately connected to heart valve tissue remodeling and repair, as well as initiation of pathological processes. Given the complex three-dimensional VIC structure and associated biomechanical behaviors, we developed a VIC computational continuum mechanics model to determine changes in stress fibers contraction and strain rate sensitivity. Novel experimental data was acquired including stress fiber orientation, expression levels of F-actin and α-SMA, as well as microindentation studies...
